effect of dietary fat on individual long-chain fatty acyl-coa esters in rat liver and skeletal muscle.the effect of dietary fat on the long-chain acyl-coa ester profile of liver and skeletal muscle was investigated by feeding weanling rats 12%-fat diets composed of high-linoleic safflower oil (73% 18:2n-6), high-oleic safflower oil (70% 18:1n-9) or olive oil (70% 18:1n-9) for six and ten weeks. approximately 50% of both hepatic and skeletal muscle acyl-coa esters comprised linoleoyl-coa or oleoyl-coa with high-linoleic or oleic feeding, respectively. total hepatic acyl-coa ester concentration wa ...19892761358
effect of dietary alpha-linolenate/linoleate balance on collagen-induced platelet aggregation and serotonin release in rats.male sprague-dawley rats at 3 weeks of age were weaned to a diet supplemented either with perilla seed oil [alpha-linolenic acid (alpha-lna)/linoleic acid (la) = 3.66] or with safflower seed oil (alpha-lna/la less than 0.01) for 5-6 weeks. the eicosapentaenoic acid (epa)/arachidonic acid (aa) ratio in platelet phospholipids was much higher in the perilla oil group than in the safflower oil group. platelet aggregability determined turbidometrically varied greatly among individual animals, and the ...19892776241
determination of oil oxidation by an aldehyde-requiring mutant of luminous bacteria.a simple, rapid bioluminescence test (bt) for the determination of lipid oxidation is described. the test utilizes an aldehyde-requiring dark mutant of vibrio harveyi (m42) that emits light in the presence of long chain (c8-c16) aliphatic aldehydes. the procedure consists of treating the oil or fat with co2+ ion in ethanolic medium at alkaline ph. this treatment facilitates the decomposition of the hydroperoxides into long-chain aldehydes, part of which is used by the bacteria to produce light. ...19892782108
attenuation of the febrile response in guinea pigs by fish oil enriched diets.the influence of dietary lipid manipulation on the fever response to an injection of murine recombinant interleukin-1 (ril-1) in guinea pigs was examined. the animals were fed diets identical except for the lipid source for periods of 5 and 6 wk. in vitro thromboxane b2/b3 (txb2/b3) production in collagen-stimulated whole blood was also measured. one diet was enriched with menhaden oil, high in the omega-3 series of fatty acids. the other diet contained safflower oil, consisting primarily of the ...19892785221
lack of an influence of dietary fat on murine natural killer cell activity.the influence of the degree of saturation and the concentration of dietary fat on murine natural killer (nk) cell activity was investigated using c3h/hen and c57bl/6n mice. mice were fed purified diets containing either 0% fat (fat free), 5 or 20% safflower oil or 5 or 20% palm oil. safflower oil and palm oil were used because they are comparable in carbon chain length but vary in the amount of linoleic acid [18:2(n-6)]. cytotoxicity of splenic nk cells from mice stimulated or unstimulated by th ...19892795245
effect of acidic ph on the protein carmin from safflower seed (carthamus tinctorius).the effect of a decrease in ph on the structural integrity of carmin has been monitored by a variety of biophysical techniques. the protein undergoes initial dissociation up to ph 3.5-4.0 without any significant denaturation. below this ph the process of dissociation and denaturation appears to be simultaneous. further, in the ph range of 2.5-1.6 the protein reassociates to probably a different polymer resulting from possibly, an entropically driven hydrophobic interaction. the process of dissoc ...19892803516
hypotriglyceridemic effect of dietary n - 3 fatty acids in rats fed low versus high levels of linoleic acid.the effect of dietary alpha-linolenic acid (linseed oil) or eicosapentaenoic acid (fish oil) on serum and liver triacylglycerol levels in rats fed diets rich in saturated fatty acids (hydrogenated beef tallow) versus high in linoleic acid (safflower oil) was examined. feeding fish oil with hydrogenated tallow lowered the serum triacylglycerol concentration while the combination of fish oil and safflower oil failed to do so. inclusion of fish oil in the hydrogenated tallow diet lowered the triacy ...19892804063
the effects of dietary fish oil on hepatic high density and low density lipoprotein receptor activities in the rat.rats were fed either a standard ration diet or that diet supplemented with 8% by wt of a marine fish oil or safflower oil. after 10 days, plasma triacylglycerols, total cholesterol, high density lipoprotein (hdl) cholesterol, hepatic cholesterol and fatty acid synthesis and hepatic low density lipoprotein (ldl) receptor activity were significantly depressed while hdl receptor activity was significantly increased in rats fed fish oil. fish oil-induced effects on cholesterol metabolism in the rat ...19872820793
effect of a fish-oil-supplemented diet on inflammation and immunological processes in rats.the effect of a diet enriched in fish-oil-derived fatty acids including eicosapentaenoic acid (epa) and docosahexaenoic acid (dcha) in inflammation and immunological processes in rats has been investigated. rats on a normal chow diet were given 500 mg/kg/day epa and 333 mg/kg/day dcha by gavage over a period of 50 days. control groups received water, oleic acid or safflower oil. acute and chronic phases of inflammation induced by antigenic challenge with bovine serum albumin were examined in the ...19872820885
significance of eicosapentaenoic acid (epa) in nutritional support.changes in the fatty acid profile of plasma total lipids in patients maintained on tpn were determined in 2 studies. in the first study, 20 newborns, 2-25 days of age, receiving comparable nitrogen, calories and fat were divided into 2 groups of 10 in each. a safflower oil emulsion (liposyn 20%) containing no alpha-linolenic acid was given to the group 1 subjects, while a modified emulsion containing 3% of alpha-linolenic acid in safflower oil supplying 5.6% of total calories was given to those ...19872824378
the effect of dietary eicosapentaenoic acid on arachidonic acid incorporation and metabolism in rat leukocytes.arachidonic acid (aa) released from membrane phospholipids by phospholipase a2 during cell activation is the major polyunsaturated fatty acid precursor in mammals for the cyclooxygenase and lipoxygenase pathways. eicosapentaenoic acid (epa), a major polyunsaturated fatty acid in fish oils competes with aa for these enzymes. the resulting products from epa are generally less potent than the corresponding aa metabolites which may explain the beneficial effects of this oil in reducing thrombotic an ...19872829281
membrane handling of calcium in essential hypertension.several abnormalities have been described in the blood-cell handling of calcium in patients with hypertension and rats with genetic hypertension. we have suggested elsewhere that the multiple abnormalities of monovalent and divalent ion handling by blood cells in hypertension, which are loosely and variably associated with blood pressure, reflect a global variability of cell membrane lipids. in the light of this suggestion we tested the relevance of decreased membrane binding of calcium by exami ...19872831320
gammalinolenic acid-enriched diet alters cutaneous eicosanoids.there are reports that vegetable oils containing gammalinolenic acid (gla) may exert beneficial effects on inflammatory skin disorders. to determine whether or not dietary gla exerts any modulatory role on cutaneous eicosanoids, guinea pigs were fed either a control diet containing safflower oil (less than 0.5% gla) or borage oil, a gla-rich diet containing 25% gla. after an 8-week feeding period, epidermal samples from both animal groups were analyzed for fatty acid composition and tissue eicos ...19882841938
fish oil reduces cholesterol and arachidonic acid content more efficiently in rats fed diets containing low linoleic acid to saturated fatty acid ratios.rats were fed diets containing a high level of saturated fatty acids (hydrogenated beef tallow) versus a high level of linoleic acid (safflower oil) at both low and high levels of fish oil containing 7.5% (w/w) eicosapentaenoic and 2.5% (w/w) docosahexaenoic acids for a period of 28 days. the effect of feeding these diets on the cholesterol content and fatty acid composition of serum and liver lipids was examined. feeding diets high in fish oil with safflower oil decreased the cholesterol conten ...19882844278
effect of varying concentrations of linoleic acid on alpha-adrenoceptor responses in spontaneously hypertensive rats.the effect of increased intake of linoleic acid on the alpha-adrenergic system was assessed by safflower oil supplementation to spontaneously hypertensive rats. linoleic acid-enriched intake at 5%, 15% and 30% by weight of total food intake for 12 wk was associated with a reduction in resting arterial blood pressure, while heart rate and heart to body weight ratios were similar to control group values. a dose-response analysis to norepinephrine bitartrate administered intravenously indicated a s ...19882845438
reversal of epidermal hyperproliferation in essential fatty acid deficient guinea pigs is accompanied by rapid generation of inositol triphosphate.this study probes the extent of coupling between the reversal of epidermal hyperproliferation induced by essential fatty acid (efa) deficiency in guinea pigs, the hydrolysis of epidermal phosphatidylinositol 4,5-bisphosphate (ptdins4,5p2), and the rapid formation of inositol triphosphate (insp3). our data revealed that the incorporation of free [3h]-inositol into phosphatidylinositol 4p and ptdins4,5p2 of microsomal preparations from hyperproliferative epidermis was markedly elevated when compar ...19882845870
effect of dietary fish oils on the formation of leukotriene b4 and b5, thromboxane and platelet activating factor by rat leukocytes.1. this study investigates the effect of dietary eicosapentaenoic acid (epa), in the form of 'max epa' fish oil, on leukotriene b4 (ltb4) production in ionophore-stimulated rat leukocytes. male wistar rats (200-250 g) were fed for 3 weeks on a synthetic chow supplemented with either 10% by weight max epa oil or a coconut oil/safflower oil mixture. 2. the epa-rich diet significantly increased the epa content of leukocyte phospholipids and decreased the arachidonic acid level by 35% (p less than 0 ...19882856061
effect of dietary alpha- and gamma-linolenic acid on tissue fatty acids in guinea pigs.guinea pigs were fed regular chow diets supplemented with 5% (by weight) safflower oil, evening primrose oil, or linseed oil for 6 weeks. the unsaturated fatty acid content of these oils was 78.9% of 18:2n6, 74.1% of 18:2n6, and 9.2% of 18:3n6, or 21.5% of 18:2n6 and 46.9% of 18:3n3, respectively. in comparison with 18:2n6, dietary supplementation with 18:3n6 significantly increased the tissue levels of 18:3n6 and 20:3n6, whereas dietary 18:3n3 significantly elevated the levels of 18:3n3 in plas ...19852857052
comparison of the clinical and biochemical effect of increased alpha-linolenic acid in a safflower oil intravenous fat emulsion.we report the results of a randomized comparison of two intravenous safflower oil (fat) emulsions in neonates who required total parenteral nutrition. the fat emulsions differed only in their content of alpha-linolenic acid: in one emulsion the alpha-linolenic acid content of the oil was 0.1% of fatty acids, while in the other emulsion the alpha-linolenic acid content of the oil was 3.0 +/- 1.5% (sd) of fatty acids. group 1 and 2 patients received the "low" and "high" alpha-linolenic acid emulsi ...19852859362
influence of dietary lipids on the effect of chlorpromazine on membrane properties of rabbit red cells.the effect of diets containing different types of common natural oils on physical properties of red cells was investigated by using rabbits. the rabbits were fed for 18 months on a standard diet in which 8% of its energy content was provided by safflower oil and 32% energy by either more safflower oil or fish oil, linseed oil, olive oil or palm oil. erythrocyte deformability was significantly decreased by the fish oil diet compared with each of the other diets. osmotic fragility was significantl ...19862870499
inhibition of liver lipogenesis by dietary polyunsaturated fat in severely diabetic rats.diabetic and nondiabetic rats were used to ascertain if dietary polyunsaturated fats inhibited hepatic acetyl-coa carboxylase and fatty acid synthetase in insulin-insufficient rats as had been previously shown for normal rats. male rats were rendered diabetic (400-600) mg glucose/100 ml blood) with streptozotocin and were fed a high fructose fat-free diet. safflower oil or palmitate (or tallow) was added to the basal fructose diet at a level to supply 12,24 or 36% additional digestible energy. c ...19862876068
effect of dietary alpha-linolenate/linoleate balance on brain lipid compositions and learning ability of rats.spontaneously hypertensive rats (shr) and normotensive control, wistar/kyoto (wky) rats through two generations were fed a semipurified diet supplemented either with safflower oil (rich in linoleate) or with perilla oil (rich in alpha-linolenate). the cerebral lipid contents and phospholipid compositions did not differ between the two dietary groups of shr rats. there were also no differences in the unsaturated/saturated ratios of individual phospholipids or the proportions of plasma-logens. how ...19872883248
impaired platelet aggregation and thromboxane generation in essential fatty acid-deficient rats.adp-induced platelet aggregation and thrombin-induced thromboxane b2 generation in diluted whole blood from rats fed a fat-free diet supplemented with 10% (by weight) hydrogenated coconut oil [essential fatty acid (efa) deficient] were significantly lower than that in animals fed 10% safflower oil [(sfo) rich in linoleic acid] or 10% marine oil (rich in eicosapentaenoic acid and docosahexaenoic acid). plasma fibrinogen levels were significantly lower and liver function was impaired in the efa-de ...19872888839
selective incorporation of n-3 and n-6 fatty acids in essential fatty acid deficient rats in response to short-term oil feeding.essential fatty acid deficient male sprague dawley rats were fed for 7 days a fat-free semi-synthetic diet supplemented with 10% by weight of different oil supplements. the oil supplement was a mixture of olive, safflower and linseed oils prepared at different proportions so the dietary n-9/n-6/n-3 ratios were approximate 2/1/1, 1/2/1, 1/1/2, and 1/1/1. the fatty acid compositions of plasma and liver lipids were then examined. our results show polyunsaturated n-6 and n-3 fatty acids were selecti ...19872898942
effect of the dietary alpha-linolenate/linoleate balance on lipid compositions and learning ability of rats. ii. discrimination process, extinction process, and glycolipid compositions.donryu strain rats through two generations were fed semi-purified diets supplemented with safflower seed oil (rich in linoleic acid) or with perilla seed oil (rich in alpha-linolenic acid), or a conventional laboratory chow (normal control diet). brightness-discrimination learning ability was determined to be the highest in the perilla oil-fed group, followed by the normal group, and then by the safflower group, extending our earlier observation in a different strain of rat that alpha-linolenic ...19882903207
differential effects of dietary linoleic and alpha-linolenic acid on lipid metabolism in rat tissues.comparative effects of feeding dietary linoleic (safflower oil) and alpha-linolenic (linseed oil) acids on the cholesterol content and fatty acid composition of plasma, liver, heart and epididymal fat pads of rats were examined. animals fed hydrogenated beef tallow were used as isocaloric controls. plasma cholesterol concentration was lower and the cholesterol level in liver increased in animals fed the safflower oil diet. feeding the linseed oil diet was more effective in lowering plasma choles ...19882903427
effects of dietary alpha- and gamma-linolenic acid on lipid metabolism in young and adult rats.the effect of age on lipid metabolism was studied in rats fed diets containing safflower oil (sfo, 78% linoleic acid), evening primrose oil (epo, 9.4% gamma-linolenic acid and 70% linoleic acid) or the mixture of safflower and linseed oil (slo, 10.2% alpha-linolenic acid and 68% linoleic acid). the activity of hepatic hmg-coa reductase declined with age in all groups. in adult rats, the reductase activity was high in the epo group and low in the slo group. the activity of hepatic cholesterol 7 a ...19882903713
docosahexaenoic acid and other dietary polyunsaturated fatty acids suppress leukotriene synthesis by mouse peritoneal macrophages.the efficacy of individual omega-3 polyunsaturated fatty acids (pufa) in altering eicosanoid synthesis in peritoneal macrophages was studied by feeding mice for 10 days a diet containing 2 wt % fat, which included 0.5 wt % ethyl esters of eicosapentaenoic acid (epa), docosahexaenoic acid (dha) or linolenic acid (lna). upon stimulation with calcium ionophore a23187, macrophages from these animals produced significantly lower amounts of leukotriene c4, leukotriene b4 and 12-hydroxyeicosatetraenoic ...19882904636
effect of dietary alpha-linolenate/linoleate balance on mean survival time, incidence of stroke and blood pressure of spontaneously hypertensive rats.following the suckling period, stroke-prone spontaneously hypertensive rats (shr-sp) were fed semi-purified diets supplemented either with safflower seed oil (rich in linoleic acid) or with perilla seed oil (rich in alpha-linolenic acid). the mean survival time of male shr-sp fed the perilla diet was longer than that fed the safflower diet by 17% (p less than 0.001) while the difference was 15% in female shr-sp (p less than 0.05). the mean survival times of female shr-sp were more than 40% longe ...19882905408
modulation of hepatic ferrochelatase activity by dietary manipulation of mitochondrial phospholipid fatty acyl groups.ferrochelatase is an enzyme bound to the inner mitochondrial membrane, which is important in heme biosynthesis. activity of purified ferrochelatase is affected by the presence of certain fatty acids. in the present study, we examined whether the activity of ferrochelatase is altered by dietary manipulation of the composition of mitochondrial membrane phospholipid fatty acyl groups. rats were fed diets containing triolein, safflower or menhaden oil as 5% (w/w) of the diet. after 3 weeks, the anim ...19892925161
preference for high carbohydrate over various high fat diets by diabetic rats.streptozotocin-diabetic male rats were hyperphagic relative to nondiabetic controls when offered only high carbohydrate (cho) laboratory chow. diabetics and controls ate about the same amount of high fat diets made from 67% w/w chow and 33% either coconut oil (saturated) or safflower oil (unsaturated). however, when offered a simultaneous choice of high fat diets and chow, nondiabetics and low dose (35 mg/kg) streptozotocin-diabetics showed a preference for the high fat diet: in contrast the hig ...19852933752

essential fatty acids in the liver and adipose tissue of genetically obese mice: effect of supplemental linoleic and gamma-linolenic acids.genetically obese mice (ob/ob) and their lean litter-mates were given diets iso-energetically supplemented with sucrose, hydrogenated coconut oil, safflower oil or evening primrose (oenothera biennis) oil. weight gain over 15 weeks was significantly greater in the evening primrose oil-supplemented obese mice than in the other groups. in all the groups of obese mice, liver total phospholipids contained proportionally less linoleic acid and more dihomo-gamma-linolenic acid and arachidonic acid tha ...19852998443
abnormal essential fatty acid composition of tissue lipids in genetically diabetic mice is partially corrected by dietary linoleic and gamma-linolenic acids.genetically diabetic mice (db/db) and their non-diabetic litter-mates were maintained for 15 weeks on diets supplemented with safflower oil or evening primrose (oenothera bienis) oil, both essential fatty acid (efa)-rich sources, or hydrogenated coconut oil (devoid of efa). plasma glucose was higher in the diabetic mice supplemented with the oils than in the unsupplemented diabetic mice. in the oil-supplemented non-diabetic mice, plasma glucose did not differ compared with the unsupplemented non ...19852998444
the chloroplast genome of carthamus tinctorius.a physical map of safflower (carthamus tinctorius l.) chloroplast dna has been generated using sali, psti, kpni and hindiii restriction endonucleases. southern blots to single and double digests by these enzymes were hybridized with 32p-dctp nick-translated kpni probes, which were individually isolated from agarose gels. the plastid genome was found to be circular (151 kbp), to contain a repeated sequence of about 25 kbp, and to have small and large single copy regions of approximately 20 and 81 ...19853001501
effect of dietary saturated fatty acids on hormone-sensitive lipolysis in rat adipocytes.the objective of this work was to examine the mechanism by which dietary saturated fatty acids, as compared with polyunsaturated fatty acids, lower hormone-sensitive lipolysis in rat adipocytes. rats were fed a purified diet containing 14% of a fat with a high concentration of either saturated fatty acids (coconut oil or beef fat) or polyunsaturated fatty acids (safflower oil) as a control. in addition, each diet contained 2% corn oil. the animals were fed these diets for 4 wk. norepinephrine-st ...19863014093
the importance of lipid type in the diet after burn injury.the effects of different types of dietary lipids were tested in burned guinea pigs. all diets were identical except for the type of lipid, with total energy intake from lipids equaling 10%. all animals received a 30% total body surface area (tbsa) flame burn and were fed identically by pump-controlled gastrostomy feedings for 14 days. when compared to safflower oil (74% linoleic acid) as well as linoleic acid alone, fish oil (18% eicosapentaenoic acid or epa) administration resulted in less weig ...19863015058
fat induced hypertension in rabbits: the effects of dietary linoleic and linolenic acid.it has been suggested that dietary linoleic and gamma-linolenic acid may be hypotensive. fat enriched diets increase blood pressure, and the effects of linoleic and linolenic acids on this increase have been investigated. after a control period on a low fat diet, rabbits were given four fat enriched diets containing different proportions of linoleic, gamma-linolenic and alpha-linolenic acids for 8 weeks, and returned to the low fat control diet for 3 weeks. blood pressures were measured non-inva ...19863029216
influence of dietary fats on cell populations of line 168 mouse mammary tumors: a morphometric and ultrastructural study.the effect of dietary fat concentration and saturation on cell composition and structure of line 168 mouse mammary tumors in vivo was studied using morphometry and electron microscopy. both the concentration and saturation of fat fed to mice had a significant influence on the volume ratio of mast cells infiltrating line 168 tumors. tumors of mice fed diets containing a high concentration (20%) of either safflower oil (so) or palm oil (po) had 2-3 times the volume ratio of mast cells than mice fe ...19873036343
fatty acid intake and kupffer cell function: fish oil alters eicosanoid and monokine production to endotoxin stimulation.diets high in n-3 fatty acids appear to have an anti-inflammatory effect, which is thought to be due to decreased macrophage prostaglandin (pg) and thromboxane (tx) production after incorporation of these fatty acids into cell membrane phospholipids. the effect of n-3 fatty acids incorporation on macrophage monokine release in response to septic stimuli is not well established. kupffer cells, the fixed macrophages of the liver, were obtained from rats fed diets with fat sources derived from corn ...19883041642
lipodystrophic diabetes mellitus. investigations of lipoprotein metabolism and the effects of omega-3 fatty acid administration in two patients.we investigated the metabolic effects of omega-6 (safflower oil) and omega-3 (fish oil) fatty acid-enriched diets (65% carbohydrate, 20% fat) in two patients with a syndrome of diabetes mellitus, lipodystrophy, acanthosis nigricans, chylomicronemia, and abdominal pain. 3h-glycerol was used to evaluate triglyceride-rich lipoprotein-triglyceride (trlp-tg) metabolism, and changes in glucose and insulin dynamics were also studied. on the omega-6 diet, both subjects demonstrated four- to five-times n ...19883050365
effects of omega-3 fatty acids in hypertriglyceridemic states.in the experimental studies reported in this review, dietary omega-3 fatty acids from fish and fish oil had profound hypolipidemic effects in normal subjects and in hypertriglyceridemic patients with combined hyperlipidemia (type iib) and type v hyperlipidemia. in these studies, 68 adults participated in carefully controlled metabolic experiments. in all subjects and patients, there were marked reductions in plasma cholesterol and triglyceride concentrations, with triglyceride lowering being esp ...19883051392
cholesterol levels and eicosanoid production in rats fed phosphatidylinositol or soybean lecithin.male young rats were fed 8% corn oil diets supplemented either with 2% phosphatidylinositol (pi) from safflower seeds or soybean lecithin (sl) for 22 days. other groups of rats were fed 10% corn oil diets with or without (control) 0.3% inositol (in, equivalent to the inositol moiety of the pi diet). the plasma cholesterol level was low in the sl group whereas liver triglyceride was low in all supplemented groups. the aortic production of prostacyclin tended to be high in rats fed the control die ...19883054022
novel triglycerides for special medical purposes.the clinical use of intravenous lipid emulsions have been routine for over 25 years. for most of that time period the use of the vegetable oils, soybean and safflower, were the exclusive lipid source for these emulsions. recently intravenous medium-chain triglycerides have been commercially available. this review will discuss several important new research developments coming from the laboratory which should prove to enhance the nutritional effectiveness as well as minimize the adverse effects o ...19883063836
the effect of diet on the spontaneous insulin dependent diabetic syndrome in the rat.we have fed rats prone to developing spontaneous insulin dependent diabetes mellitus (iddm) defined diets in which casein was the sole source of protein and the fat content was either menhaden oil, safflower oil, or corn oil. the incidence of iddm was compared to that in litter mates fed rat chow. animals receiving the defined diets had a lower frequency of overt iddm than did animals receiving rat chow. the effect was seen only when the diet was introduced before the animals had reached the age ...19883073033
stability of liposyn ii fat emulsion in total nutrient admixtures.compatibility and safety of a safflower oil-soybean oil lipid emulsion (liposyn ii, abbott) with amino acids and dextrose in total nutrient admixtures (tnas) were studied. sixty-two admixtures representing 31 different combinations of fat emulsion, amino acid injection, and dextrose injection were tested. both 10% and 20% concentrations of the fat emulsion and three concentrations each of amino acid injection and dextrose injection were used; the core admixture components were placed in empty fl ...19863087165
effects of dietary triglycerides on serum and liver lipids and sterol excretion of rats.the effects of several highly purified simple and mixed dietary triglycerides (tgs) on serum and liver cholesterol and on sterol excretion were studied in rats. the tgs contained 4- to 18-carbon fatty acids with melting points of -75 to 63.5 degrees c. ratios of polyunsaturated to saturated fatty acids ranged from 0.1 to 105. ratios of total unsaturated to saturated fatty acids ranged from 0.1 to 115. all diets contained 8% tg plus 0.82% safflower oil. sterols were quantified directly by a new a ...19863088226
high density lipoprotein accumulation in perfusates of isolated livers of african green monkeys. effects of saturated versus polyunsaturated dietary fat.to determine whether altered hepatic secretion of hdl is part of the mechanism by which polyunsaturated fat lowers plasma hdl concentration, we have studied hdl secretion in the isolated perfused livers of african green monkeys fed an atherogenic diet containing either safflower oil as the polyunsaturated fat or butter as the saturated fat. during recirculating perfusion with a lipoprotein-free medium, livers from safflower oil-fed animals produced 21% less hdl mass on the average than those fro ...19863090181
partial correction by exogenous lipid of abnormal patterns of polyunsaturated fatty acids in plasma phospholipids of stressed and septic surgical patients.polyunsaturated fatty acid (pufa) profiles are abnormal in a variety of clinical conditions that are commonly seen in the surgical intensive care unit. pufa profiles in the serum phospholipids were studied by capillary gas chromatography in 22 critically ill, hypermetabolic surgical intensive care unit patients. all patients received continuous total parenteral nutrition (tpn) by central vein with trace elements and vitamins. eleven patients received daily supplementation with 50 gm of safflower ...19863094185
medium chain triglycerides and structured lipids.lipids are an essential component of our body composition and necessary in our daily food intake. conventional fats and oils are composed of glycerides of long chain fatty acids and are designated as long chain triglycerides (lct). body fat as well as the fats and oils in our daily intake fall into this category. in enteral and parenteral hyperalimentation, we can identify such lct fats and oils. soy, corn, safflower and sunflowerseed oils are typical of the lct oils. in the search for alternati ...19873112486
medium chain triglycerides and structured lipids as unique nonglucose energy sources in hyperalimentation.this brief review will discuss recent work concerning new intravenous lipid emulsions for future use in clinical patients. intravenous lipid emulsions currently available in the united states are derived from soybean or safflower oils and serve as sources of nonglucose, nitrogen-sparing calories and the essential fatty acid linoleic acid. because of concerns that much of the infused long chain triglyceride is not oxidized readily and that there may be some immune system impairment, newer emulsio ...19873112487
cutaneous application of safflower oil in preventing essential fatty acid deficiency in patients on home parenteral nutrition.essential fatty acid deficiency (efad) is observed in patients with massive bowel resection who are placed on home parenteral nutrition (hpn). we investigated the use of cutaneously applied safflower oil to prevent efad. five subjects on hpn supplemented with intravenous (iv) fat emulsions underwent a three-phase study: 1) no iv fat emulsions for 4 wk; 2) cutaneous safflower oil for 4-6 wk; 3) oral safflower oil for 4 wk. fatty acid profiles (fap) of plasma were obtained during each phase. signi ...19873115080
toxicity of palmitoyl glycerol to mice: depression of thyroid function.mice given propylthiouracil, a thyroid inhibitor, and fed a diet containing a nontoxic level of rac-1(3)-palmitoyl glycerol showed the hypothermia and mortality expected for a toxic dose, but did not show these signs when linoleate or oleate was added to the diet. loss of radioiodine from the whole animal and thyroid gland was slower when mice were fed the toxic palmitoyl glycerol diet than when fed the same diet containing 4% safflower oil. however, mice fed the two diets did not differ in the ...19873117986
increased vascular reactivity induced by essential fatty acid deficiency in rat autoperfused hindquarters.the effects of essential fatty acid deficiency (efad) on vascular reactivity to vasoconstrictor stimuli were studied in rat autoperfused hindquarters. weanling male sprague-dawley rats (aged 21 days) were fed diets containing 8% (weight/weight) of stearax plus 2% safflower oil (control diet) or 10% stearax (efad diet) for 8 weeks. there was no difference in systemic blood pressure or body weight between the two groups. basal production of immunoreactive 6-keto-pgf1 alpha by aortic segments was m ...19883127460
effects of dihydrotestosterone administration with and without estradiol pretreatment on gonadotropin secretion in ovariectomized pony mares.twenty ovariectomized pony mares were used to determine if dihydrotestosterone propionate (dhtp) administration, with or without estradiol benzoate (eb) pretreatment, would have the same effects on follicle stimulating hormone (fsh) and luteinizing hormone (lh) secretion as testosterone propionate (tp) administration. all mares were given an initial injection of gonadotropin releasing hormone (gnrh) to characterize their lh and fsh response, and then two groups of mares (n = 4/group) were admini ...19873149231

enhanced survival to endotoxin in guinea pigs fed iv fish oil emulsion.improved survival to endotoxin has been demonstrated in rats pretreated with cyclooxygenase inhibitors or made essential fatty acid deficient, implying that excessive omega 6 fatty acids, possibly through their eicosanoid products, contribute to mortality. following endotoxin administration, we also have shown improvement in survival with oral diets supplemented with fish oil. this study sought to explore whether parenteral fish oil ameliorates the adverse impact of endotoxin. male hartley-strai ...19883172993
effects of dietary fish oil on platelet function and plasma lipids in hyperlipoproteinemic and normal subjects.we studied the effects of dietary supplementation with an encapsulated fish oil concentrate (maxepa) on platelet function, fibrinolysis, and plasma lipids and lipoproteins in 9 normal subjects, 10 patients with type iv hyperlipoproteinemia, and 6 with type iib hyperlipoproteinemia. after a baseline period, the subjects crossed over randomly between treatment periods with maxepa (providing 3.24 g eicosapentaenoic acid and 2.16 g docosahexaenoic acid per day) and safflower oil (used as a control), ...19883178928
effect of fish oil concentrate on lipoprotein composition in niddm.non-insulin-dependent diabetes mellitus (niddm) is associated with elevated very-low-density lipoprotein (vldl) triglyceride concentrations and abnormalities of low-density lipoprotein (ldl) composition. because fish oil supplementation may favorably affect lipid and lipoprotein concentrations in nondiabetic subjects, we determined the effect of fish oil concentrate on plasma lipids and lipoprotein composition in patients with niddm. dietary-supplementation 1-mo periods of 4.0 and 7.5 g of omega ...19883181646
dietary manipulation of macrophage phospholipid classes: selective increase of dihomogammalinolenic acid.because alterations in the dietary content of fatty acids are an important method for modulating macrophage eicosanoid production, we have quantitated the levels of n-6 and n-3 polyunsaturated fatty acids in peritoneal macrophage individual phospholipids from mice fed diets (3 wk) with either safflower oil (saf), predominantly containing 18:2n-6, borage (bor) containing 18:2n-6 and 18:3n-6, fish (mfo) containing 20:5n-3 and 22:6n-3, and borage/fish mixture (mix) containing 18:2n-6, 18:3n-6, 20:5 ...19883185109
linoleic acid-induced fatty acid changes in platelet and aorta of the rat: effect of age and cholesterol.the influence of age and cholesterol on polyunsaturated fatty acids (pufa) levels was studied in young and old male sprague-dawley rats. animals were fed a fat-free diet supplemented with 10% (by wt) safflower oil with or without 1% cholesterol for 8 wk. as a result of cholesterol feeding, proportions of linoleic acid (18:2n-6) and dihomo-gamma-linolenic acid (20:3n-6) were increased and that of arachidonic acid (20:4n-6) was decreased in the liver and platelet phospholipids in 64-wk-old rats, s ...19883185125
the effects of omega 3 and omega 6 fatty acid-enriched diets on plasma lipoproteins and apoproteins in familial combined hyperlipidemia.there is abundant evidence that dietary omega 3 fatty acids effect a favorable change in lipoprotein profiles of normolipidemic individuals. however, there is relatively little information available on the lipoprotein responses of hyperlipidemic individuals at risk for premature coronary artery disease. we studied a group of subjects with familial combined hyperlipidemia (fchl), as well as a group of normal controls, on three rigidly controlled diets differing primarily in their fatty acid compo ...19883185285
effects of type of dietary fat on indices of immune status of rabbits.we have compared the effects of dietary saturated and unsaturated fats of the n-6 and n-3 types on the immune status of male new zealand white rabbits. four groups of rabbits (n = 8) were fed purified diets containing one of the following fats (7.6% w/w, 23 kcal%) for 5 mo, hydrogenated soybean oil (hso); safflower oil (sfo); linseed oil (lso); or menhaden oil (mho). in vitro proliferation of peripheral blood lymphocytes (pbl) cultured with t-cell mitogens was significantly higher in the lso gro ...19883193254
toxicity of rac-1(3)-myristoyl glycerol to mice.when a diet containing 30% rac-1(3)-myristoyl glycerol was fed to mice, they developed hypothermia and death occurred within a few days. if 4% safflower oil was added to the diet containing the myristoyl glycerol, hypothermia did not develop and the mortality decreased. there was a pronounced effect of ambient temperature on the toxic effects of rac-1(3)-myristoyl glycerol. overall, the effects of feeding rac-1(3)-myristoyl glycerol paralleled the previous findings with rac-1(3)-palmitoyl glycer ...19883210075
carnitine supplementation vs. medium-chain triglycerides in postburn nutritional support.the effect of dietary supplementation of carnitine on protein metabolism was studied in a burned guinea-pig model. animals bearing a 30 per cent total body surface area burn were enterally infused with three isocaloric and isonitrogenous diets via gastrostomy feeding tubes for 14 days. two diets contained safflower oil (long-chain triglycerides, lct) and another diet contained medium-chain triglycerides (mct) as their lipid sources (30 per cent of total calories as lipid). l-carnitine was added ...19883228696

association-dissociation and denaturation-renaturation of high-molecular-weight protein: carmin from safflower seed (carthamus tinctorius l.) in alkaline solution.the effect of alkaline ph on the association, dissociation, and denaturation of carmin, the high-molecular-weight protein from safflower seed was investigated in the ph range 7-12, using various biophysical techniques. the results indicate that the multimeric protein carmin dissociates at ph 8.0 where denaturation has not set in. the association-dissociation of the protein can be represented schematically as 11s in equilibrium 7s in equilibrium 4s----2s. above ph 10, the protein undergoes simult ...19883252893
protection of the rat myocardium from ischemic injury by dietary lamprey oil.the lamprey (entosphenus japonicus martens) has been recommended in japan as an efficacious diet for curing some of chronic inflammatory disorders. fresh lamprey is rich in n-3 unsaturated fatty acids (e.g., eicosapentaenoic and docosahexaenoic acids) with minimal seasonal variation. the dietary effect of lamprey oil on acute myocardial ischemia was therefore investigated. rats were fed a control diet or a diet supplemented with 5% safflower oil (so) or 5% lamprey oil (lo) for 4 weeks. after cor ...19883273220
effects of various combinations of omega 3 and omega 6 polyunsaturated fats with saturated fat on serum lipid levels and eicosanoid production in rats.the effects of varying the ratio of polyunsaturated/saturated fatty acids (p/s) and omega 3/omega 6 polyunsaturated fatty acids (pufa) of dietary fats on lipid metabolism were studied in rats using safflower oil (sfo), linseed oil (lso), palm oil (plo), and a 1:1 combination of these oils. the hypocholesterolemic and hypotriglyceridemic effects depended on the p/s ratio of dietary fats, lso (omega 3 pufa) being more effective than sfo (omega 6 pufa). a similar pattern of the response was observe ...19883292727
fish oil prevents insulin resistance induced by high-fat feeding in rats.non-insulin-dependent diabetes mellitus is an increasingly prevalent disease in western and developing societies. a major metabolic abnormality of non-insulin-dependent diabetes is impaired insulin action (insulin resistance). diets high in fat from vegetable and nonaquatic animal sources (rich in linoleic acid, an omega-6 fatty acid, and saturated fats) lead to insulin resistance. in rats fed high-fat diets, replacement of only 6 percent of the linoleic omega-6 fatty acids from safflower oil wi ...19873303333
effect of dietary fats and carbohydrate on blood pressure of mildly hypertensive patients.the effect on blood pressure (bp) of replacing dietary saturated fat with either polyunsaturated fat (linoleic acid) or carbohydrate was studied in 21 untreated mildly hypertensive patients. in a randomized, double-blind, crossover protocol, all subjects received dietary supplements of cream, safflower oil, and carbohydrate in random sequence, each prepared in flavored yogurt or milk. each supplement was administered for 6 weeks and followed by a 4-week washout period of no supplementation. diet ...19873308702
dietary suppression of prostaglandin synthesis does not accelerate doca/salt hypertension in rats.1. this study investigated the effects of dietary modification of prostaglandin (pg) synthesis on blood pressure regulation in doca/salt-treated rats. 2. after an initial 4 week period on either a 2-series pg 'inhibitory' diet of fish oil (max epa), a 'stimulatory' diet of safflower oil or a control diet of saturated fat, three groups of rats were placed on a doca/salt regimen for a further 4 weeks. another group on the saturated fat diet continued their diet without doca/salt administration. 3. ...19873315335
diacylglycerol acyltransferase in maturing safflower seeds: its influences on the fatty acid composition of triacylglycerol and on the rate of triacylglycerol synthesis.diacylglycerol acyltransferase in a particulate preparation from maturing safflower seeds showed no strict selectivity for acyl-coa when acyl-coa substrates were administered as mixtures. this suggested that the fatty acid composition of position 3 in safflower triacyl-sn-glycerol exclusively depends on the acyl-coa composition in the cell. the specific activity of the acylation was approximately 3 nmol/min per mg protein of the preparation under the optimum assay conditions. this low activity a ...19883334861
preferential metabolism by macrophages of conditioned rabbit hypercholesterolemic remnant lipoproteins.rabbits were fed a diet containing 1% cholesterol, and lipoproteins were isolated from their plasma by sequential ultracentrifugation. lipoprotein remnants (d = 1.019-1.063) were conditioned by incubation with bovine aortic smooth muscle cells for 24 h and then incubated for 4 h with j774 cells or mouse peritoneal macrophages. conditioning of remnants and low-density lipoproteins resulted in enhancement of their uptake and metabolism by the macrophages in culture. the macrophages metabolized con ...19883349092
repression of pentose phosphate pathway dehydrogenase synthesis and mrna by dietary fat in rats.we have studied the effects of polyunsaturated fatty acid and its metabolism on the activity, relative synthesis and mrna levels for rat hepatic glucose-6-phosphate dehydrogenase (g6pd) and 6-phosphogluconate dehydrogenase (6pgd). rats were meal-fed high carbohydrate diets containing either no fat, 5% safflower oil or 5% safflower oil + eicosa-5,8,11,14-tetraynoic acid (tya). hepatocytes were isolated and used as a source of rna, de novo radiolabeled protein and postmitochondrial supernatant for ...19883351636
polyunsaturated fatty acids and protection of newborn rats from oxygen toxicity.to test whether polyunsaturated fatty acids (pufa) might be associated with protection against oxygen toxicity in newborn experimental animals, we performed two series of experiments. in the first series, adult female rats were fed one of three diets--regular rat chow, a high-pufa (safflower oil-based) diet, or a low-pufa (palm oil-based) diet--for several weeks before and throughout pregnancy and lactation. newborn offspring of the three diet groups had similar antioxidant enzyme activities and ...19883351690
