| lipid transport systems: some recent aspects in swine, cattle and trout during development. | lipids such as triacylglycerols, free and esterified cholesterol and phospholipids are essentially insoluble in water; lipoproteins, which are complex macromolecules of pseudomicellar structure, have evolved to ensure their efficient transport in the vascular system of vertebrates. plasma lipoproteins are operationally classified according to their relative lipid and protein contents and thus according to density. the protein components, i.e. apolipoproteins, have a highly specialized structure ... | 1985 | 3887526 |
| nucleoside transport and metabolism in erythrocytes from the yucatan miniature pig. evidence that inosine functions as an in vivo energy substrate. | erythrocytes from the yucatan miniature pig, like those from the normal domestic pig, lack functional glucose transporters and were unable to utilize plasma glucose as an energy source. in contrast, inosine and adenosine entered the cells rapidly. the nucleoside transporter responsible for this uptake was identified as a band 4.5 polypeptide (5000 copies per cell; apparent mr 45 000-66 000). inosine concentrations in the physiological plasma range (1.6-2.5 microm) were found to maintain normal e ... | 1985 | 3902093 |
| [animal experiment studies on the healing of bone transplants by clamping plate fixation following hyperthermic denaturation]. | the re-use of resident bone transplants after hyperthermic denaturalization is demonstrated in radiologically, clinically, and histologically in the lower jaw of the domestic pig. periosteal and enosteal osteogenic effect is induced. | 1985 | 3909673 |
| influence of light and photoperiodicity on pig prolificacy. | in the wild pig mating activity is seasonal. the main breeding period is in late autumn but a second period may occur around april. it is known from other species that seasonal variations in breeding activity are mainly regulated by photoperiod. in the domestic pig seasonal influences on prolificacy still exist: for example, ai boars not only show decreased steroid synthesis, sperm counts and libido in summer compared with the optima which occur in winter but also a biphasic pattern with a trans ... | 1985 | 3910824 |
| the epidemiology of african swine fever: the role of free-living hosts in africa. | the known distribution of african swine fever (asf) virus in africa is reviewed in relation to the distributions of its free-living hosts as are the infection rates of these species in different localities in southern africa. mechanisms by which asf virus is maintained in its sylvatic state and ways in which the infection may enter domestic pig populations are discussed. | 1985 | 3911134 |
| [in vitro oxidation of [u-14c] palmitate, [1-14c] and [6-14c] glucose in newborn and adult rats and pigs]. | studies have been made on the intensity of oxidation of [u-14c]-palmitate, [1-14c]- and [6-14c]-glucose by slices of the liver and skeletal muscles of new-born, 1-day, 5-day and adult wistar rats and domestic pigs. it was found that the level of 14co2 production from these substrates is higher in tissues of rats than in those of pigs. at early stages of ontogenesis, in tissues of both species intensive oxidation of glucose is observed together with oxidation of fatty acids. in the course of onto ... | 1985 | 3920843 |
| measurement by electrical impedance aggregometry of porcine platelets response to selected physiological agonists. | although the domestic swine is commonly employed for physiological studies of the coronary circulation, there is relatively little data available concerning the responsiveness in whole blood of normal porcine platelets to standard physiological agonists. such information is essential if the domestic swine is to be used as an animal model for studying potential interactions between platelets and the coronary circulation. accordingly, the present study was undertaken to characterize the responses ... | 1985 | 3923491 |

| regeneration of epidermis by cells grown in tissue culture. | pig epidermal cells were grown in vitro for 21 to 180 days, forming multilayered sheets of epidermis varying from thirteen to forty layers. for an evaluation of their use in wound coverage, they were transplanted onto surgically prepared full-thickness wound beds on domestic swine. autologous epidermal cells were studied on twenty-five of the animals, and allogeneic epidermal cells were studied on thirteen. autologous epidermal cells grown in vitro provided functional wound coverage 10 to 15 day ... | 1985 | 3973141 |
| effects of calcium entry blockers on coronary constriction and myocardial ischemia due to leukotriene d4. | recent studies show that leukotrienes (lts) produce profound coronary artery constriction. although calcium entry blockers are commonly used to remedy coronary vasospasm, their capacity to interfere with lt-mediated coronary constriction is unknown. therefore, we compared effects of intracoronary ltd4 before and during treatment with calcium entry blockers in the in situ, blood-perfused hearts of domestic pigs. intravenous administration of verapamil (0.1-1.6 mg/kg), nifedipine (10 or 100 microg ... | 1985 | 3981457 |
| notes on placentation in the suina. | we examined the gross and microscopic anatomy of placental tissues and umbilical cords from six species representing the three living families of the suina. these species included, of the suidae, the wart hog (phacochoerus aethiopicus), the giant forest hog (hylochoerus meinertzhageni), the domestic pig (sus scrofa), and the banded pig of malaysia (sus scrofa vittatus); of the tayassuidae, the white-lipped peccary (tayassu pecari); of the hippopotamidae, the hippopotamus (hippopotamus amphibius) ... | 1985 | 3991477 |
| group r streptococci: wild boars as a second reservoir. | group r streptococci have caused many cases of septicaemia and meningitis in patients handling live or slaughtered pigs which were the only known reservoir of group r streptococci. a human case, due to a wild boar, is reported here and it is therefore concluded that there exist both a domestic (pig) and a wild (wild boar) reservoir of group r streptococci. | 1985 | 3992197 |
| trichinella spiralis: acquired immunity in swine. | the ability of domestic pigs to develop protective immunity to trichinella spiralis in response to inoculation with different doses of muscle larvae was assessed. adult worms developing from the inoculations of 112, 500, and 10,000 larvae were expelled from the intestine about 6 weeks after inoculation. inoculation with 25,000 larvae, however, resulted in more rapid intestinal worms expulsion, indicating that gut expulsion is dose dependent. secondary expulsion also tended to be dependent upon p ... | 1985 | 3996525 |
| comparison of lung antioxidant levels in humans and laboratory animals. | basal lung concentrations of ascorbic acid (aa), nonprotein sulfhydryls (npsh), and alpha-tocopherol (alpha-t) were determined in rabbits, guinea pigs, rats, hamsters, mice, domestic pigs and sheep, and in human lung samples obtained from cancer surgery patients. significant differences were found among the laboratory animals: aa levels ranged from 25.6 mg% (mg/100 g wet weight) in hamsters to 41.7 mg% in mice, npsh from 50.9 mg% in rats to 84.7 mg% in rabbits, and alpha-t from 1.01 mg% in hamst ... | 1985 | 4003918 |
| histologic and temperature alterations induced by skin refrigerants. | the histologic alterations induced by spray refrigerants independent of and in combination with dermabrasion were studied with the use of the domestic pig as a model. tissue injury was found to be a function of spray duration and freeze intensity. both preabrasion freezing and postabrasion refreezing could produce damage additive to that of mechanical planing. skin surface and intradermal temperature variations during refrigeration were recorded. the possible implications of these findings as th ... | 1985 | 4008684 |
| peripheral plasma prolactin concentrations during oestrous cycles in different types of primitive gilt. | plasma prolactin concentrations were determined by radioimmunoassay during oestrous cycles and around the time of oestrus in different types of primitive gilts: vietnamese, zlotnicka and wild-boar x domestic pig hybrids. the animals were bled without stress from an indwelling arterial catheter. the following results were obtained: (1) in all gilts the main prolactin peak was observed at day 15 or 16 of the oestrous cycle; (2) vietnamese and hybrid gilts showed a second smaller prolactin surge af ... | 1985 | 4038515 |
| assignment of the porcine major histocompatibility complex to chromosome 7 by in situ hybridization. | the major histocompatibility complex (sla) of the domestic pig (sus scrofa) was regionally mapped to 7p12----q12 by in situ hybridization with an sla class i-specific recombinant dna probe. this localization contradicts linkage data suggesting a possible assignment of the sla locus to porcine chromosome 15. | 1985 | 4042688 |
| topical chemotherapy of intradermal walker 256 carcinosarcoma with diaziquone and doxorubicin in the rat. | a model for metastatic skin cancer using intradermal injection of walker 256 carcinosarcoma has been developed in the rat. using this model, antitumor activity of topically applied doxorubicin and diaziquone in vanicream, plastibase, and dimethyl sulfoxide (dmso) as vehicles was compared with intraperitoneal injection of the drugs at the same doses beginning 4 days after injection of tumor cells. doxorubicin applied topically at 0.5 mg/day for 4 days in vanicream or plastibase exhibited no antit ... | 1985 | 4053022 |
| effects of different-shaped tissue expanders on transluminal pressure, oxygen tension, histopathologic changes, and skin expansion in pigs. | this study, performed on domestic pigs, was designed to show whether the shape and size of a tissue expander influences the amount of surface area increase. when a defect is irregular, a larger custom-fitted implant is more efficient than several smaller expanders. oval implants gained 5 percent more skin using 50 percent less time and almost 20 percent less intraluminal pressure, while u-shaped implants yield 2.2 percent more skin in 10 percent less time with 35 to 50 percent less pressure when ... | 1985 | 4059413 |
| reperfusion before global ischemic arrest improves the salvage of infarcting myocardium. | to study the effect of hypothermic global ischemic arrest on an evolving myocardial infarction and of perfusion of the ischemic zone or region at risk before global ischemia, 62 farm pigs underwent 15, 30, or 60 minutes of reversible coronary occlusion. twenty-eight of these animals served as controls: reflow to the region at risk was established by removal of the coronary occluder without the addition of global ischemia. another 26 animals had similar periods of coronary occlusion and then were ... | 1985 | 4062403 |
| a four-year survey of african swine fever in malawi. | a serological survey of free-ranging domestic pigs in the central and southern regions of malawi, together with laboratory data on confirmed cases of african swine fever (asf) and data from interviews with pig owners, undertaken over a four-year period from 1981-4, has enabled the asf enzootic area of malawi to be identified. the area covers much of the western part of the central region and includes mchinji district and parts of kasungu, ntchisi, dowa and lilongwe districts. mortality is substa ... | 1985 | 4067292 |
| [effect of sodium selenite on the course of acute experimental myocardial infarct]. | the effect of sodium selenite on experimental myocardial infarction was investigated in 47 domestic pigs, with a major emphasis on the hemodynamic antiarrhythmic effects of selenium. intravenous sodium selenite administered in a dose of 1-2 mg/kg body weight produced a favorable pharmacologic effect. the hemodynamic action consisted in an increase of heart rate, and the maximum aortic flow rate, cardiac output, minute volume of the heart and coronary flow, as well as a decrease in total peripher ... | 1985 | 4079230 |
| [mathematical formulations of the fetal mass growth in cattle]. | after a short review of investigations into fetal weight growth of cattle, the first mathematical treatment of values gained by swett and collaborators (1948) and approximated by simple power functions after a proposal from bereskin and touchberry (1967) is recalled. thereafter values for the weight of fetus and uterus with content as summarized by huth (1962) are approximated with growth functions applying nonlinear regressions. the 6 functions taken into consideration range from classical to q ... | 1985 | 4096405 |
| endoscopic treatment of bronchus stump fistulae following pneumonectomy with fibrin sealant in domestic pigs. | occlusion of the transected bronchus after pneumonectomy was achieved by transthoracic fibrin sealing in 14 domestic pigs. in 9 additional animals standardized bronchus stump fistulae could also be closed with fibrin sealant which was applied through a flexible bronchoscope. an average of 1 ml of fibrin sealant containing 500 units of thrombin and 3500 units of aprotinin was necessary to achieve bronchial closure and to prevent early dissolution of the sealant. endoscopic closure of a bronchus f ... | 1985 | 2417369 |
| the oxygen affinity of mammalian hemoglobins in the absence of 2,3-diphosphoglycerate in relation to body weight. | we studied the oxygenation of mammalian hemoglobins: mouse (mus musculus molossinus), rabbit (oryctolagus cuniculus domesticus), japanese monkey (macaca fuscata), man (homo sapiens), sheep (ovis aries), llama (lama glama), pig (sus scrofa domesticus), cow (bos taurus domesticus) and horse (equus caballus), in the absence of 2,3-diphosphoglycerate (dpg) and compared their oxygen affinity in relation to the body weight. the negative correlation between body weight and the oxygen affinity of the wh ... | 1985 | 2866879 |
| ontogeny of neuropeptidergic systems: luteinizing hormone releasing hormone (lhrh); somatostatin (srif) and neurophysin (nf) in the hypothalamus of the domestic pig by immunocytochemistry. | the ontogenic development of some hypothalamic neuropeptides: luteinizing hormone releasing hormone (lhrh); somatostatin (srif) and neurophysin (nf) and their localization in the hypothalamus of fetuses in different stages of the fetal life were studied by immunoperoxidase method. it was found that differentiation of the neurons which produce the examined hormones begins in the midstage of pregnancy. lhrh is stored in the nerve terminals of the median eminence (me) and organum vasculosum of the ... | 1985 | 2867938 |
| detecting changes of arterial and venous blood flow in flaps. | island skin flaps based on the latissimus dorsi muscle were raised in domestic pigs. simultaneous recordings of laser doppler flowmetric and laser photometric values were made on the skin in the middle of the flap. occlusion of either the artery or the vein of the pedicle was accompanied by very low laser doppler flow values. in laser photometry the total intensity of backscattered light remained unchanged or was sightly increased during arterial occlusion. in response to venous occlusion, howev ... | 1985 | 2935062 |
| comparison of intraosseous, central, and peripheral routes of sodium bicarbonate administration during cpr in pigs. | obtaining venous access continues to be one of the most difficult problems faced by a physician caring for the pediatric patient in cardiac arrest. our study examined the use of the intraosseous route (through the bone) to obtain venous access for sodium bicarbonate administration in a cardiac arrest model. ventricular fibrillation was induced in 23 domestic swine. cardiopulmonary resuscitation was performed for five minutes and sodium bicarbonate (1 meq/kg) was administered through a peripheral ... | 1985 | 2998236 |
| substance k: vascular and cardiac effects in rat and pig. | the effects of substance k (sk), a newly discovered tachykinin, on the cardiovascular and sympathetic system were evaluated in the pithed rat preparation and in the in situ domestic pig heart. in pithed rats, sk (10 nmol/kg, iv) produced a triphasic mean blood pressure (map) response: short depressor, short pressor (+11 +/- 1 mmhg), and prolonged depressor phase (-9 +/- 1 mmhg, n = 9-24, p less than 0.001). neither effect was significantly affected by pretreatment with propranolol (2 mg/kg) or p ... | 1985 | 3001674 |
| strain-specific 1.7 kilobase repetitive deoxyribonucleic acid sequence family in trichinella spiralis. | eco ri digestion of bulk dna from trichinella spiralis p1, an isolate from domestic pig, reveals the presence of families of repetitive sequences. one of the most prominent of these has a monomer size of 1.7 kb, which exists in minimally dispersed direct tandem arrays, with a copy number of about 2800, and represents 2% of the genome. although there is evidence that the eco ri site is missing in some of the family members and that a 1.9 kb variant of the sequence also occurs, the family is highl ... | 1986 | 3027555 |
| protective immunity to ascaris suum: analysis of swine peripheral blood cell subsets using monoclonal antibodies and flow cytometry. | outbred domestic swine or sla inbred miniature swine were exposed to ascaris suum either naturally on contaminated lots or by inoculation with uv-irradiated attenuated eggs. both inbred and outbred swine developed virtually complete protection to a challenge of 10 000 eggs after natural exposure, but inbred swine were less resistant than outbred swine after uv-egg exposure. flow cytometric analysis of peripheral blood mononuclear cells from these animals, performed to determine changes in cell s ... | 1986 | 2939618 |
| a preliminary comparison of trypanosoma simiae and t. congolense by isoenzyme electrophoresis. | trypanosoma simiae, although similar to t. congolense in morphology and mode of development in the tsetse vector, is regarded as a separate species mainly because it is highly pathogenic to the domestic pig and fails to infect rodents. to establish whether the two species are distinct biochemically, we compared by isoenzyme electrophoresis 2 isolates of t. simiae with 7 stocks of t. congolense, together with one of t. brucei. all isoenzyme patterns of the 6 enzymes examined differed in t. simiae ... | 1986 | 2872783 |

| production and evaluation of specific antisera against sera of various vertebrate species for identification of bloodmeals of glossina morsitans centralis. | specific antisera against sera of 46 species of vertebrates were prepared. the antisera to 21 bovidae species were raised in goats except the antiserum to goat serum which was raised in sheep. the antisera to 3 suidae species were produced either in domestic pigs or warthogs, while antisera to most of the other vertebrate species were raised in rabbits. the antisera were used in an enzyme-linked immunosorbent assay (elisa) to identify the source of bloodmeals ingested by teneral and non-teneral ... | 1986 | 2882665 |
| similar epidermal changes in hyperkeratotic scabies of humans and pigs. | we compared some morphological and biochemical aspects of the epidermal changes occurring in hyperkeratotic scabies in humans and domestic pigs. clinically and histologically, pig skin alterations look very similar to those observed in humans, i.e., brittle hyperkeratosis with parakeratotic crusting and thickening of the epidermis. parakeratosis seems to correspond to previous passage of scabies mites through the incompletely differentiated layers of the epidermis. indeed, by serial sectioning w ... | 1986 | 2425653 |
| conservation of diagnostic antigen epitopes among biologically diverse isolates of trichinella spiralis. | crude and immunoaffinity-purified excretory-secretory antigens derived from a domestic pig isolate of trichinella spiralis were used in an enzyme-linked immunosorbent assay to test serum from mice infected with 25 different pig and wild animal isolates of t. spiralis sspp. all of the sera were found positive by elisa using either of the antigen preparations, indicating all isolates shared certain antigen epitopes. excretory-secretory antigens were prepared from 3 distinct isolates of t. spiralis ... | 1986 | 2434638 |
| [effect of iloprost on aggregation behavior in kidney conditioning and changes in iloprost concentration in kidney preservation]. | the conditioning of the donor by 1.0 microgram/kg x min iloprost over 15 minutes leads to a considerable inhibition of the aggregation of thrombocytes in the domestic pig. 160% more adp had to be added than before the application of iloprost. when 0.5 microgram/ml iloprost are added to the perfusion fluid and to the reperfusion fluid 0.22 microgram/ml and 0.27 microgram/ml, respectively, are to be proved in the venous efflux. whether or not the difference is absorbed or metabolized must remain o ... | 1986 | 2437731 |
| comparison of experimental hypercholesterolemia and atherosclerosis in göttingen mini-pigs and swedish domestic swine. | mini-pigs of the göttingen strain and domestic swine of the swedish landrace were compared with respect to their susceptibility to alimentary hypercholesterolemia and experimental atherosclerosis. hypercholesterolemia was produced in both strains by adding 11.2% egg yolk and 0.5% cholesterol to the diet. the plasma cholesterol rose significantly faster and reached a higher level in the mini-pigs than in the domestic swine. in both strains most of the elevated plasma cholesterol was found in the ... | 1986 | 3964345 |
| assignment of the major histocompatibility complex to the p1.4----q1.2 region of chromosome 7 in the pig (sus scrofa domestica l.) by in situ hybridization. | the pig major histocompatibility complex (sla) was mapped by in situ hybridization. the probe used was a human cdna containing most of the coding sequence for hla-b7. the sla complex was localized to the region p1.4----q1.2 on chromosome 7. | 1986 | 3082605 |
| [epidemiologic survey of the cysticercosis endemic on réunion island]. | the high incidence of cysticercosis was underestimated in reunion island before computed tomography (january, 1984). in 1974, soulayrolles et boyer-vidal found that cysticercosis was responsible for 0.5 p. 100 of the cases of epilepsy. in hospitalized people, routine cranial and muscles radiographies detected: 1/among 242 epileptics: 183 men: 36 positive (19.67 p. 100); 59 women: 9 positive (15.25 p. 100), 2/among 166 non epileptic-related neurological disorders: 106 men, 6 positive (5.66 p. 100 ... | 1986 | 3797934 |
| storage of pathogenic leptospires in liquid nitrogen. | the virulence and viability of various serovars of leptospira interrogans were successfully preserved by storage in liquid nitrogen. dimethyl sulphoxide at a final concentration of 2.5% (v/v) was added as cryoprotectant to a culture of leptospires grown in ellinghausen-mccullough-johnson-harris medium. ampoules were cooled at a controlled rate of 1 degree-3 degrees c/min to -70 degrees c, then transferred to the liquid phase of a liquid nitrogen storage unit. glycerol was discounted as a cryopro ... | 1986 | 3804861 |
| electrophoretic polymorphism of erythrocyte leucine aminopeptidase in the wild boar, sus scrofa. | an erythrocyte leucine aminopeptidase (rbc lap) electrophoretic polymorphism was detected in italian wild boars, sus scrofa. such a polymorphism has not previously been reported in the domestic pig. it is suggested that this locus could be a marker for genetic differences between the domestic and the wild forms of sus scrofa. | 1986 | 3826759 |
| morphological characteristics of the gyrus dentatus in some animal species and in man. | comparative anatomical investigations have been carried out on the gyrus dentatus of rat, fox, cattle, domestic pig, monkey (cercopithecus sabeus) and man. after removal of the brain stem and scaling off the brain substance from the medial aspect towards the lateral aspect, the gyrus dentatus was preserved and its relation with regard to the hippocampus, the fimbria hippocampi and the gyrus parahippocampalis was studied. a rat's gyrus dentatus occupies a rather wide zone on the medial aspect of ... | 1986 | 3717598 |
| porcine coccidia in papua new guinea. | faecal samples from 232 domestic pigs raised on concrete, 98 free-ranging village pigs, and five wild boar showed 46.6 (108/232), 54 (53/98) and 80% (4/5) prevalence of coccidian oocysts, respectively. eight species of eimeria, and isospora suis, were recovered. in their descending order of predominance in the pigs raised on concrete, the species of coccidia were e. debliecki (26.7%), e. scabra (22.4%), e. neodebliecki (19.8%), e. porci (15.5%), e. suis (11.6%), e. polita (8.6%), e. perminuta (7 ... | 1986 | 3727342 |
| chromosomal localization of leukocyte interferon gene in the pig (sus scrofa domestica l.) by in situ hybridization. | using as a probe pig genomic dna, including the complete interferon alpha gene, we have mapped the leukocyte interferon gene on pig chromosome 1 by in situ hybridization. a total of 196 silver grains were noted on the 106 metaphases scored: 31% of the grains were observed on chromosome 1, and 67% of these were localized in the region 1q2.2----q2.7. | 1986 | 3731881 |
| [individual variability and inheritance of the number and size of the nucleolar organizer regions in chromosomes of domestic swine]. | individual variability of the number and size of silver-staining nucleolar organiser regions (nor) was studied in 76 pigs of semirechenskaya, big white and duroc breeds. the variability of the nor number is exclusively caused by the presence of the 8nor- allele (the chromosomes of the 8th homologous pair lacking the silver-staining nor). concentration of the 8nor- allele is about 0.7 in the average for all three breeds. all 7 offsprings from the homozygous parents male 8nor- /8nor- and female 8n ... | 1986 | 3732795 |
| polygraphic analysis of the sleep-wake states and the rem sleep periodicity in domesticated pigs (sus scrofa). | electrocorticography and concurrent electromyography were used during a total of nineteen 24 hr periods in three juvenile pigs in order to establish the quantitative duration of the sleep-wake states and the rem sleep cycles. wakefulness (w), drowsiness (dr), slow-wave sleep (sws) and paradoxical sleep (rem) occupied respectively 46.5%, 15.9%, 26.7% and 10.9% of the 24 hr period. mean duration of episodes was 4.1 min for dr, 6.2 min for sws and 3.3 min for rem. sleep cycles (sc) duration was 13. ... | 1986 | 3737741 |
| [unsaturated fatty acids in the lipids of the spermatozoa of ovis amon aries l. and sus scrofa domestica l]. | spectrophotometric investigations were carried out with five unsaturated fatty acids found in the composition of spermatozoid lipids of animals belonging to four breeds of ovis amon aries l. parallel comparative analysis were made of the fatty acids in the lipids extracted from spermatozoa of landrace swine of the sus scrofa domestica l. species. differences were established as to the percent content of fatty acids, having low points of freezing. it is believed that the criterion of cold resista ... | 1986 | 3765375 |
| the analgesic effect of buprenorphine, etorphine and pethidine in the pig: a randomized double blind cross-over study. | in order to find a suitable analgesic for the treatment of postoperative pain in pigs the analgesic effect of buprenorphine, etorphine and pethidine has been compared in 8 domestic pigs. for assessment of the analgesic action on thermal (hot plate) and two mechanical (cannulation of ear vein, needle prick) noxious stimuli have been employed. in a pilot experiment on 2 pigs in which methadone was included the maximal effective doses were estimated for each drug. methadone was found unsuitable bec ... | 1986 | 3766147 |
| povidone-iodine in polyethylene oxide hydrogel dressing. effect on multiplication of staphylococcus aureus in partial-thickness wounds. | we studied the ability of a polyethylene oxide hydrogel dressing (vigilon) containing povidone-iodine to prevent staphylococcus aureus proliferation in partial-thickness wounds. we previously reported that a single application of povidone-iodine on wounds challenged with 2 x 10(6) s aureus was not effective in reducing the number of s aureus after 24 hours. it was therefore hypothesized that povidone-iodine might be effective if it was available continuously and applied to wounds containing a sm ... | 1986 | 3767400 |
| effect of a reduction in blood viscosity on maximal myocardial oxygen delivery distal to a moderate coronary stenosis. | this study tested the hypothesis that a reduction in blood viscosity by means of isovolumetric hemodilution will permit an increase in maximal oxygen delivery to myocardium distal to a moderate coronary arterial stenosis. it is known that blood viscosity is a determinant of resistance to blood flow at both the stenotic and the arteriolar levels. accordingly, a reduction in blood viscosity could exert a favorable influence on maximal myocardial oxygen delivery in the setting of stenosis, provided ... | 1986 | 3769166 |
