[role of alimentary hyperglycemia in the pathogenesis of several disorders of lipid metabolism].alimentary hyperglycemia in rabbits was found to be accompanied by increase in cholesterol level, as well as in the amount of triglycerides in the blood sera. progressive increase in the serum concentration of pre-beta lipoproteids (serving as endogenous tryglyceride carrier) has also been demonstrated. a short-term feeding with cholesterol against the background of hyperglycemia in rabbits appeared to result in early marked atherosclerotic changes, as compared to those in control group of normo ...1976182301
avian leukosis viruses of different subgroups and types isolated after passage of rous sarcoma virus-rous-associated virus-0 in cells from different ring-necked pheasant embryos.avian leukosis viruses of subgroups a and f (rav-a and rav-f) arose at a low rate after passage of rous sarcoma virus-rous-associated virus-0, which is subgroup e, in cells from ring-necked pheasant embryos. in cells of two embryos, all of the viruses isolated after virus passage were rav-f. however, in cells of a third embryo, both rav-a and rav-f were isolated. in addition, there sometimes were type-specific differences among the different isolates of rav-a and rav-f from the cells of single e ...1976183006
[herpesvirus-induced autoantibodies in animals (author's transl)].after immunization with autologous testicle cells which were infected with herpes virus hominis type 1 or 2, histologically homogeneous, eosinophilie pas-positive substances could be detected in five out of six rabbits, mainly within the interstitium. these substances have been found by immunofluorescence microscopic techniques to be antibodies against testicle tissue.1976183633

studies on in vitro carcinogenesis. i. autoradiographic and biochemical study on the incorporation of labelled methylcholantrene into mouse embryonic cells.the incorporation of radioactive labelled methylcholanthrene into cba/t6t6 mouse embryonic fibroblast cultures was studied by using light and electronmicroscopic autoradiographic and also liquid scintillation counting techniques. during 24 hrs treatment time at the applied methylcholanthrene concentrations (0.01-2.5 mug/ml) the proportion of cells labelled with 3h-methylcholanthrene and the number of grains above the cells showed a relationship with the duration of treatment and also with the do ...1976130740
[influence of microflora on the metabolism of l-threonine at the level of the rat digestive tract].intestinal tissues are found to incorporate l threonine 14cu at faster rate in the absence of microflora. most of the radioactivity of the digestive contents occurs in the tca soluble compounds, except in the coecum and large intestine of the conventional rats where the microflora synthetized its own proteins from the labelled digestive material. free threonine is the main labelled soluble compound in the conventional rats digestive contents. in the other hand, in the germfree rats digestive con ...1976134804
[synchronous electric activity with inspiration in the vastus lateralis muscle of the anesthesied dog breathing spontaneously].in the dog, under chloralose or pentobarbitone anesthesia and breathing spontaneously, a muscular electrical activity of low voltage synchronous with respiration was observed in m. vastus lateralis. the mean maximum amplitude of this activity is inversely linked with respiratory rate. when the respiratory frequency is equal or exceeds 25 cycles per minute this activity disappears. such a phenomenon seems to be related to the activity of the respiratory centre.1976134813

an investigation of the homology of guanylate kinase isozymes in mammals and further evidence for multiple guk gene loci.guanylate kinase in the red cells of 63 different mammalian species was studied by electrophoresis and multiple molecular forms of the enzyme were found in all species. two species were investigated in more detail. using molecular weight estimates as a criterion of homology, the fallow deer and the chinese hamster were found to have isozymes that corresponded to isozyme e, f, and g of man. variation in the guanylate kinase isozymes was detected in a small population of orangutans. results sugges ...1977201245
electron microscopic studies on equine infectious anemia virus (eiav). brief report.morphological studies of eiav reveal knobs on the surface of the particles, conically and tubularly shaped cores, budding particles with dense crescents directly underlying the plasma membrane, and distinct intracytoplasmic structures in infected cells.1977202230
vitamin d metabolism.during the past decade, an explosion of information has become available on the metabolism and function of vitamin d which is of great importance to clinicians in the treatment of metabolic bone disease. we have learned that vitamin d is the precursor of at least one hormone and that this hormone carries out functions in calcium and phosphorus metabolism bringing about mineralization of bone on one hand, and the prevention of hypocalcaemic tetany on the other. it may also function in the prevent ...1977203416
the influence of crude cottonseed oil in the feed on the blood and egg yolk lipoproteins of laying hens.lipovitellin, very low density lipoproteins (vldl), low density lipoproteins (ldl), high density lipoproteins (hdl), and proteins of d greater than 1.20 were isolated from blood plasma and egg yolks obtained from hens fed a normal diet or one containing 2.5% of crude cottonseed oil. the amounts and compositions of each fraction were determined. hen blood plasma and egg yolk vldl and ldl obtained from hens fed a normal diet contained similar levels of lipid, and the fatty acid compositions of tho ...1977203909
ecophylaxis: preventive treatment with gentamicin of rabbit lincomycin-associated diarrhea.in rabbits the oral or parenteral administration of lincomycin result in a severe and usually fatal form of diarrhea. the rabbits treated simultaneously with lincomycin and gentamicin do not present any sign of disease and behave exactly, therefore, as the control subjects. the same occurs in subjects treated with gentamicin alone. in all the subjects which died with diarrhea there was a marked alteration of the intestinal bacterial flora. among the aerobic bacteria there was an overgrowth of co ...1977350739

studies on the occurrence of peptococcus indolicus and corynebacterium pyogenes in abscesses in swine, and on the occurrence of pc. indolicus in apparently normal skin and mucous membranes of piglets.pc. indolicus was isolated from 42.7% and cb. pyogenes from 48.7% of 150 pus-samples from abscesses in pigs (slaughter-house material, table i). in 41 specimens the two organisms were found together. further, pc. indolicus was demonstrated in 22.4% of 290 swabs from apparently normal skin and mucous membranes of piglets (autopsy material, table ii). by gel diffusion analysis the strains of pc. indolicus were referred to the serotypes b, c, d, e, or f. the type distribution (table iii) possibly r ...197898755
[immunological relations between mother and child during pregnancy (author's transl)].the relations between the maternal and foetal organisms during pregnancy are partly very complicated and remain inexplicable. blastocyst, trophoblast, embryo and foetus have membrane antigens at a very early stage, and the immunocompetence of the foetus develops already during the second third of the pregnancy period. many non-specific factors are involved in preventing the castingoff reaction of the foetal organism. the trophoblastic tissue is probably of central importance. the focal point of ...197898927
interferon inducing activity of polyinosinic acid.although poly(i) is generally considered to be inactive as an interferon inducer, we have found several authentic poly(i) preparations to be effective inducers. their interferon inducing ability varied considerably from one cell system to another. in human diploid fibroblasts, primed with interferon and superinduced by cycloheximide and actinomycin d, all active poly(i) samples proved nearly as effective in inducing interferon as poly(i).poly(c). in primary rabbit kidney cell cultures, the activ ...197899486

behaviour of solute and particle markers in the stomach of sheep given a concentrate diet.1. fistulated sheep given a concentrate diet were used to study the behaviour of solute ([51cr]edta) and particle ([103ru]phenanthroline) markers in the stomach under conditions of continuous feeding. 2. an injection of a mixed dose of [51cr]edta and [103ru]phenanthroline was given into the rumen and the time course of marker concentrations in the rumen and the abomasum was recorded. the curves were analysed on the assumption that the stomach of the sheep could be represented as two mixing compa ...197896850
[antimicrobial activities of two strains of streptomyces albus isolated from african soils].the antibiotic activity of these two strains of s. albus is facilitated by culture on slices of potatoes. streptomyces extracts show an antibiotic activity against gram-positive and gram-negative bacteria and an antifongic activity aginst nearly all aspergillus. these antimicrobial effects bring hope of a utilization against some mycotoxin pollution, or mold attacks.197896972
[nature of the mutations that determine the ability of bacillus subtilis a-50 to sporulate at high glucose concentrations in the medium].the ability of bacillus subtilis a-50 to sporulate in the medium containing high glucose concentrations is caused by at least two mutation types: pts mutations and cat (or tgl) mutations, both of them affecting differently the level of alkaline proteinase synthesis. the decrease of the level of enzyme activity in the case of pts mutation (glur3 mutant) occurs at the expense of glucose transport disturbance. the mutation cat (tgl) (mutant glur5) causes the increase in enzyme synthesis at the expe ...197897172
evidence that spo0a mutations are recessive in spo0a-/spo0a+ merodiploid strains of bacillus subtilis.the spo0a locus contains two types of closely linked mutations that block sporulation at stage 0: spo0a mutations (the most pleiotropic of the stage 0 markers) and spo0c mutations. it was previously thought that spo0a mutations were dominant in merodiploids of bacillus subtilis, whereas spo0c mutations were recessive. we have shown that spo0a mutations were recessive when spo0a-/spo0a+ merodiploids were made in the genetic backgrounds of strains that were resistant to antibiotic produced by the ...197897278

radical scavenging as the mechanism for stimulation of prostaglandin cyclooxygenase and depression of inflammation by lipoic acid and sodium iodide.certain radical-trapping reducing agents have been shown to stimulate prostaglandin biosynthesis in vitro (1--6) and to depress phorbol myristate acetate-induced mouse ear edema (16). the increased prostaglandin synthesis resulted from influences on the cyclooxygenase. to ascertain whether these alterations were due to direct interaction with the enzyme or to indirect scavenging of the oxidant released during pgg2 reduction, we report the effects of lipoic acid and sodium iodide. both of these a ...1978107544
a three month inhalation toxicity study in the squirrel monkey (saimiri sciureus) with terbutaline sulfate (bricanyl).a study of the subacute toxicity of inhaled terbutaline sulfate was performed in the squirrel monkey (saimiri sciureus). 3 groups of monkeys were exposed 1 h daily 7 days/week for 3 months to terbutaline sulfate aerosols at concentrations of 0.039, 0.185 and 0.799 mg terbutaline/litre of air respectively. a fourth group was a chamber control receiving air only. the following clinical parameters were evaluated: physical appearance and behavior, weight gain, ophthalmoscopic appearance, electrocard ...1978107616
experimental transmission of wuchereria bancrofti to monkeys.infective larvae of wuchereria bancrofti from laboratory-raised culex pipiens fatigans and aedes togoi mosquitoes fed on human volunteers in jakarta, indonesia (j strain) and kinmen island, china (k strain) were introduced into taiwan monkeys (macaca cyclopis) by subcutaneous inoculation, by foot puncture, or by permitting infected mosquitoes to feed weekly on the monkeys. some animals were splenectomized and others were treated with varying regimens of immunosuppressants. necropsy was done on m ...1979107818
mechanism of folate transport in lactobacillus casei: evidence for a component shared with the thiamine and biotin transport systems.lactobacillus casei cells have been shown previously to utilize two separate binding proteins for the transport of folate and thiamine. folate transport, however, was found to be strongly inhibited by thiamine in spite of the fact that the folate-binding protein has no measurable affinity for thiamine. this inhibition, which did not fluctuate with intracellular adenosine triphosphate levels, occurred only in cells containing functional transport systems for both vitamins and was noncompetitive w ...1979108244
demonstration and characterization of specific binding sites for factor viii/von willebrand factor on human platelets.the presence of specific factor viii/von willebrand factor (fviii/vwf) binding sites on human platelets has been demonstrated by using 125i-fviii/vwf and washed human platelets. binding is ristocetin-dependent and increases in proportion to the concentration of ristocetin from 0.2 to 1 mg/ml. binding of 125i-fviii/vwf to platelets can be competitively inhibited by unlabeled human or bovine fviii/vwf, but not by human thrombin, fibrinogen, alpha 2-macroglobulin, equine collagen, or a lectin of ri ...1979108291
microscopic changes in rat tongue following experimental cryosurgery.histological changes were studied in the rat tongue for varying periods of time up to 14 days following the application of a cryoprobe to the dorsal surface of rat tongue. within minutes of the application, focal subepithelial vesiculation and hyperemia occurred. at 3 h there was evidence of damage to capillary walls, resulting in hemorrhage. arterioles and venules were thrombosed and there were degenerative changes in the muscle layer of their walls. at 6 h ventral epithelium showed evidence of ...1979108379
probenecid-induced increase of 5-hydroxytryptamine synthesis in rat brain, as measured by formation of 5-hydroxytryptophan.probenecid blocks the efflux of 5-hydroxyindole acetic acid (5-hiaa) from the central nervous system, and has therefore been used for turnover measurements of central 5-hydroxytryptamine (5-ht). this substance also elevates tryptophan (tp) levels in rat brain. in this investigation, the time courses of probenecid and tp levels in rat serum and brain after administration of probenecid were studied. maximal levels of probenecid were reached within 15 min, followed by 50% decrease of serum tp and a ...1979108699
feeding parameters with two food textures after chlordiazepoxide administration, alone or in combination with d-amphetamine or fenfluramine.chlordiazepoxide (5.0, 10.0 mg/kg) reduced the rate of eating and extended the duration of feeding in a 10 min feeding test. it also reduced the latency to feed. both fenfluramine (1.0 mg/kg) and d-amphetamine (0.25 mg/kg) acted to reduce food intake, but by differing mechanisms. fenfluramine reduced eating rate without affecting eating duration, whilst d-amphetamine reduced eating duration without reducing eating rate. the effects of chlordiazepoxide on feeding parameters were generally additiv ...1979111292
[oculomotor reflex evoked by vibrassae stimulation in the cat].the oculomotor effects of vibrissae stimulation have been studied in the "encéphale isolé" non-anaesthetized cat. intracellular recording of lateral rectus motoneurones showed an excitatory projection via the ipsilateral infraorbital nerve to these motoneurones. the afferent fibers are type a alpha, recuited with a low threshold (0.2-0.5 ma) and convey information about vibrissae displacement.1979120789

allometric radial growth in muscle, comparing fibres with strong and with weak adenosine triphosphatase activity.a large flock of male and female white turkeys (meleagris gallopavo) was reared for 22 weeks after hatching. at two weeks intervals small groups of birds were removed from the flock and killed. samples of sartorius muscles were taken from the bird nearest the mean weight for its group. transverse frozen sections were tested for atpase activity by calcium method at ph 9.4. fibres were separated into two categories (strong-atpase and weak-atpase) and their mean minimum diameters were measured with ...1979161561
the spontaneous rate of tumours in the laboratory rat: strain chbb: thom (spf).the aim of this investigation was to examine the time relationship of the rate of development of spontaneous tumours in the rat, strain chbb: thom (spf). the rats were divided into 6 groups, each of which consisted of 100 male and 100 female animals. the first group was killed at the age of 15 months, and the last group when aged 2 1/2 years. thus the time interval between sacrificing the individual groups was 3 months. spontaneous tumours seldom appear in animals up to 15 months of age except i ...1979161861
the fate of transplanted pancreatic islets in the rat.syngeneic pancreatic islets transplanted into the liver or the spleen reverse streptozotocin-induced diabetes in the rat, but allogeneic islets function only briefly and are rejected. shortly after transplantation, thrombi often form around transplanted tissue, particularly around nonislet tissue that contaminates islet preparations. these thrombi are a source of transient liver injury in recipients of intrahepatic grafts. a few days after transplantation, syngeneic islets injected into the port ...1979104625
implications for adult roles from differential styles of mother-infant bonding: an ethological study.ethological observations of maternal and infant behaviors of nine vervet monkey pairs (cercopithecus aethiops sabaeus) showed the effects of differential styles of early maternal responsiveness on later infant competence. those infants receiving the least amount of maternal responsiveness and the most time-off the mother in the first 3 months of development were more socially competent at 6 months of age. the results are discussed within current ethological "attachment" theories. the detachment ...1979105083
polychlorinated biphenyl-induced morphologic changes in the gastric mucosa of the rhesus monkey.the early morphologic events in polychlorinated biphenyl-induced lesions of the gastric mucosa of immature male rhesus monkeys (macaca mulatta) were studied in serial biopsies taken during consumption of diets containing 3, 10, 30, and 100 mg. per kg. (p.p.m.) of aroclor 1242. the severity of the lesions correlated directly with both the duration and the level of exposure. the first changes were seen after ingestion of 30 and 100 mg. per kg. for 2 weeks; changes were not seen until 10 weeks at 3 ...1979106183
[isolation and general characteristics of a group of pseudomonas aeruginosa temperate phages].eighteen temperate phages were isolated from 38 natural strains of pseudomonas aeruginosa. the phages belong to five heteroimmune groups according to the ability of lysogenic variants of the strains pao1 and pat2 to exclude the growth of the superinfecting phage. phages of the ii and v immunity groups are serologically similar; the remaining phages are not inactivated by antisera against phages b26 (ii group) and k1338 (v group). prophages of the ii, iv, and v groups are induced by uv for vegeta ...1979106221

cytofluorometric and cytochemical comparisons of normal and abnormal human cells from the female genital tract.acridine orange staining of exfoliated cells from epithelial tissues facilitates discrimination between normal and abnormal cells: abnormal cells develop highly elevated nuclear fluorescence. comparisons of acridine orange (ao) staining with propidium iodide (pi) or feulgen staining have shown that: (a) pi staining also provides highly elevated nuclear fluorescence from abnormal cells; (b) the distributions of nuclear fluorescence following ao or pi staining were usually not significantly differ ...197986579
the puzzle of "urethral syndrome": a possible answer?82 strains of slow-growing, co2-dependent, gram-positive organisms have been isolated from the urine of 9 male and 73 female patients. 100% of the men and 93% of the women had urinary symptoms at the time of isolation, and 66% of the specimens showed pyuria. these organisms might account for the urinary symptoms of some patients previously diagnosed as having "urethral syndrome". preliminary data show that, if appropriate antibacterial treatment is given, most of these patients become symptom-fr ...197986778

antigenic correlation between rat brain synaptic vesicles and rat bone marrow b lymphocytes.rabbit anti-rat brain synaptic vesicle serum reacted with thymocytes and b lymphocytes in cytotoxicity and immunofluorescence assays. quantitative absorption analysis revealed that this antiserum contained antibodies specific for antigenic determinants on the surface membrane of a subpopulation of rat bone marrow b lymphocytes.197991533
generation of a fibroblast chemotactic factor in serum by activation of complement.when serum complement is activated by either the classical or alternative pathways, a factor with an apparent 80,000 mol wt is generated that is chemotactic for human dermal fibroblasts. the origin of this serum-derived chemotactic factor (sdcf) is not known; however, it may be a cleavage product from c5 because it is inactivated by monospecific antiserum to human c5, and it is not generated when the complement system is activated in human serum deficient in c5. sdcf is not chemotactic for human ...197991624
human lung tumor-associated antigens of 32,000 daltons molecular weight.lung tumor-associated antigens of approximately 32,000 daltons were recognized by the use of sensitive radioimmunoassays and rabbit antisera, one raised against an extract of pooled human malignant lung tissues and another raised against a cell line derived from a human squamous cell carcinoma of the lung. these antigens differ from antigens described previously, including carcinoembryonic antigen and alpha-fetoprotein. the antigens were detected on 13 of 13 lung tumors (of all histologic types) ...197991695

suramin: a potent inhibitor of the reverse transcriptase of rna tumor viruses.suramin--a well-known antitrypanosomal agent--was found to exert a strong inhibitory effect on the rna-directed dna polymerase (reverse transcriptase) activity of several oncornaviruses such as moloney murine leukemia virus, murine rauscher leukemia viruses, moloney murine sarcoma virus and avian myeloblastosis virus. inhibition of enzyme activity was obtained with both endogenous viral rna and (a)n . oligo(dt) as the template-primer. suramin effected a 50% inhibition of the reverse transcriptas ...197992362

study on the significance of bronchial hyperreactivity in the bronchus obstruction after inhalation of cat dander allergen.the role of bronchial hyperreactivity in the process that leads to bronchial obstruction after inhalation of an allergen was investigated. in 30 asthmatic children selected because of a positive skin test to cat dander allergen, we measured the histamine threshold, the reaction after allergen inhalation, the allergen-specific ige concentration in serum, the lowest allergen concentration to which the intracutaneous skin test was positive (skin titer), and the histamine release of leukocytes after ...197992487
macrophage oxygen-dependent antimicrobial activity. i. susceptibility of toxoplasma gondii to oxygen intermediates.a sensitive method for evaluating extracellular parasite viability was used to determine the in vitro susceptibility of virulent toxoplasma gondii to selected oxygen intermediates. by acridine orange fluorescent staining criteria, toxoplasmas were resistant to up to either 10(-3) m reagent h2o2 or h2o2 generated by glucose-glucose oxidase. in keeping with a lack of sensitivity to h2o2, toxoplasmas contained endogenous catalase (5.7 x 10(-4) baudhuin units/10(6) organisms). the addition of a pero ...197992521
the zinc iodide-osmium (zio) reaction in the central nervous system: localization and relations to functional activity.the fine structural characteristics of zio reaction was studied in the cerebral and cerebellar cortex and olfactory bulb of the rat and in synaptosomes prepared from rat cerebellar cortex. it was concluded that: 1. organelles of different nerve cell types exhibit different zio reactions provided that the impregnation was carried out under standardized conditions. 2. 6...10 times more synaptic vesicles were stained by zio in the inhibitory terminals than in the excitatory ones. 3. zio positivity ...197992863

histochemical reactions of gastrointestinal mucosubstances with high iron diamine after prior oxidation and methylation of tissue sections.high iron diamine reactions after the prior methylation and oxidation of tissue sections with performic acid or potassium permanganate (metox-hid or ox-met-hid) in epithelial mucosubstances and in mucosal mast cells were studied in tissue samples from the human gastrointestinal tract and were compared with reactions with high iron diamine without any pretreatment (hid) and high iron diamine with the prior methylation (met-hid). high iron diamine reactions after the prior oxidation (met-ox-hid, o ...197993103
analysis of vibrio parahaemolyticus soluble antigens by employing passive hemagglutination.the passive hemagglutination assay was explored as a sensitive test of immunological reactivity of endotoxin and other antigens prepared from selected strains of vibrio parahaemolyticus. the tannic acid procedure for passive hemagglutination, commonly used with protein antigens, was the only procedure yielding good results with v. parahaemolyticus protein extracts, endotoxins, and related preparations. these results were probably due to the presence of large amounts of protein in the v. parahaem ...197993111
pneumococcal infections and the possible need for a vaccine.antibiotics and chemotherapeutics have been available for about 40 years, but still bacterial infections constitute some of the greatest problems in medicine. pneumococci causing pneumonia, bacteremia, meningitis and otitis are a leading cause of illness and death. the exact incidence and lethality of pneumococcal infections is not known, however, since they are not reportable diseases in most countries and since microbiological diagnosis is difficult. in the latest years some significant progre ...197993308
relationship of seminal volume to size and disease of the prostate in the beagle.the seminal volume of young adult beagles was correlated with the size of and disease in their prostates. the ejaculate volume of naturally collected semen increased in a linear manner with prostatic weight in dogs with normal or glandular hyperplastic prostates. this correlation was not observed in the dogs with cystic hyperplasia, in which there was a reduction in volume of 50% in the semen produced for each gram of prostate. there were no significant differences in other seminal characteristi ...197993426
