[first results of experimental animal studies on pervascular effects of indwelling intravasal catheters upon free tissue grafts. first communication (author's transl)].this is the first in a series of two papers reporting first results of studies made to set up a basic model of intraarterial perfusions in free tissue grafts. epidermal tissue grafts were obtained from thirty-two domestic pigs prior to slaughtering and pervascularly perfused for twelve to ninety-six hours. histological examinations showed that it is possible for tissue necrosis to be arrested as a prerequisite of subsequent in vivo experiments performed with the object of pervascularly supportin ...1979160152
evolution of type c viral genes: preservation of ancestral murine type c viral sequences in pig cellular dna.domestic pigs (sus scrofa) and other members of the family suidae have multiple copies of type c viral gene sequences in the cellular dna of all their tissues. partially homologous viral gene sequences are also found in cellular dna of rodents, particularly muridae. the results lead to the conclusion that type c viral genes were introduced into the suidae lineage as a result of trans-species infection by an ancestral xenotropic murine virus. the rate of evolution of the virogene sequences in the ...1975172895
factors influencing the lipolytic response of swine (sus domesticus) adipose tissue: ontogeny.swine adipose tissue was not responsive to glucagon at any age and only marginally to adrenocorticotropin (acth). the latter response could be greatly magnified and the sensitivity increased by addition of theophylline (theo). the maximal lipolytic activity (max) obtained with acth plus theo was minimal in the newborn, greatly increased in young animals, and reduced during the growing period; however, the sensitivity did not change. the max for theo (plus low epinephrine) yielded a pattern simil ...1976179622
[improved demonstration of normal lymph nodes in lymphangiograms (author's transl)].lymphography with lipiodol ultra fluid was carried out in eight domestic pigs. the purpose of the experiment was to obtain even distribution of the oil in normal lymph nodes in order to improve its diagnostic value. this was attempted by changes in pressure, temperature and by the addition of benzopyrone. by increasing injection pressure from 0.4 to 0.8 atmospheres, using a pump, it was possible to show more of the lymphatic tissue. whether this would be possible in man is still not certain. the ...1976186372
an isoelectric focusing study of acid phosphohydrolases in liver lysosomes of higher vertebrates.1. the multiple forms of acid phosphohydrolases in liver lysosomes of sus scrofa domesticus and gallus gallus domesticus were studied by use of isoelectric focusing. 2. acid phosphatase was resolved into two forms in g. gallus domesticus and three forms in s. scrofa domesticus. especially, two forms of g. gallus domesticus were different from each other in their enzymatic properties. 3. the pi values of acid atpase agreed with those of acid phosphodiesterase in g. gallus domesticus. according to ...1979318407
[histochemical investigation on the parenchyma cells of the epiphysis cerebri of cattle (bos taurus domesticus) and pig (sus scrofa domesticus) (author's transl)].the parenchyma cells of the pineal organ from 20 cattle (10 week-old female calfs, from one year to several years of age female and male cattle) and 14 pigs (8- to 9-month-old female pigs) were investigated with histochemical methods. carbohydrates are evident in a insignificant quantity. the content of lipids is very high, according to the age the quantity varying. proteins are evident, but only in small quantities. the content of ribonucleic acid is very high.1977415484

mononuclear cell infiltration of the aortic intima in domestic swine.the preparation of thick endothelial "häutchen" from microscopically lipid-free areas of the thoracic and abdominal aorta of 22 domestic pigs proved that there is a surprisingly frequent penetration of mononuclear blood cells into the subendothelial space. they are deposited on the intima in a diffuse or focal distribution as dense epi-, inter- and subendothelial cell infiltrates.1979446590
experimental infection of domestic pigs with the virus of peste des petits ruminants.pigs could be subclinically infected with pprv by inoculation or contact with infected goats. there was no evidence that the virus could spread to uninfected pigs or goats and pigs are not considered important in the epidemiology of pprv.1979462558
isolation of a new porcine enterovirus in the united states.a cytopathogenic virus isolated from an iowa farm pig with diarrhea was identified as a member of group 5 of the porcine enteroviruses. clinical signs observed in other pigs in the herd were diarrhea, debilitation and gauntness. morbidity and mortality rates were approximately 50% and 3% respectively.a group 5 porcine enterovirus had not been previously isolated in north america according to the western hemisphere committee on animal virus characterization.1977198077

[dynamics and karyotyping of a population of wild boar with clear colored fur].the population of wild boars living in the wood of chize contains 25 % of animals having a clear coloured fur. chromosomal study of these, don't reveal any anomaly of number or structure of their chromosomes. this modification seems be due to a genic mutation and not to an eventual hybridization with domestic pigs.1977143995
natural history of autologous blood clot embolization in swine.previous studies of the natural history of embolized clots in dogs have demonstrated rapid lysis, presumably because the canine fibrinolytic system is very active. the fibrinolytic activity in swine, however, is similar to humans, and for this reason the pig was chosen for our study. the gluteal branches of the external iliac artery in nine domestic swine were embolized with either unmodified or modified (heat-formed, amicar) autologous clot. in addition, three pigs were embolized with unmodifie ...1976134002
magnitude, direction and location of the resultant dipole moment of the pig heart.vectorcardiograms were obtained from 50 young domestic pigs using the nelson lead system. compensation for body size and shape is achieved and the resultant dipole moment magnitude reflects heart size. a strong relationship was found between heart size and maximum magnitude. dipole moment magnitude increased as four pigs increased from five to ten weeks of age. the dipole moment during qrs is considered in light of known pig heart excitation pattern. dipole locations during qrs, calculated by co ...1976131171
the distribution of enzymes in the epidermis of the domestic cat.with the help of enzyme histochemical methods, the distribution and activities of several oxidative and hydrolytic enzymes in the epidermis of the densely-haired domestic cat have been studied. distinct oxidative enzyme activity could be demonstrated in all epidermal layers except the stratum corneum. among the hydrolytic enzymes investigated, strong reactions for non-specific esterases were visible especially in the str. granulosum and the basal lamellae of the str. corneum. positive reactions ...197722312
saturnine gout: lead-induced formation of guanine crystals.intravenous injection of a sublethal dose of lead acetate into a domestic pig resulted in a 4.5-fold increase of guanine in the urine, indicating an impairment in the conversion of guanine to xanthine. this impairment is probably due to the inhibition of guanine aminohydrolase (guanase), since the activity of this enzyme is inhibited by pb2+ (the inhibition constant being 3.0 x 10(-6)m). postmortem histological examination revealed concretions of crystalline material in the epiphyseal plate of t ...1978622568
isolation of san miguel sea lion virus from samples of an animal food product produced from northern fur seal (callorhinus ursinus) carcasses.a virus was isolated from california sea lions (zalophus californianus californianus) and northern fur seals (callorhinus ursinus) in 1972. it was later named san miguel sea lion virus (smsv). state and federal livestock disease control agencies became concerned, because smsv was found to be indistinguishable from vesicular exanthema of swine virus and to cause (in laboratory trials) clinical signs in swine similar to those produced by vesicular exanthema of swine virus. ground carcasses of nort ...1978629435
sylvatic trichinosis in british columbia: potential threat to human health from an independent cycle.the results of a 3-year study of trichinosis in british columbia wild-life, based on the testing of more than 9,000 tissue specimens from a large variety of animal species, indicated that trichinosis is widespread among wild mammals in the southern and central parts of british columbia. this continuing survey has established that the disease is carried by at least 15 species of terrestrial mammals including 3 species of rodents. the finding of trichinella spiralis in ground squirrels and nonsyna ...1978635095

course of antibiotic sensitivities in escherichia coli and staphylococcus aureus from animals.in order to establish the evolution of resistance against the common antibiotics from the beginning of their use up to the present time, the sensitivity of escherichia coli isolated from the cecum of wild boars was determined. the mic's of e. coli from these animals in a zoological garden was examined for comparison. the samples from the wild boars were collected in five forests in the belgian ardennes. the mic's obtained (table 1) are comparable to the mean values given in the early literature ...1979397700
precautions in the application of immunohistochemical techniques to tissues of the pig hypothalamo-neurohypophysial system.immunohistochemical procedures were used to localize neurophysin in the hypothalamo-neurohypophysial axis of the domestic pig. the topographical distribution of neurophysin as revealed by the immunofluorescence "sandwich" technique was similar to that found when either the immunoglobulin-peroxidase bridge method or the peroxidase-labeled gamma-globulin technique was employed. however, application of the peroxidase-anti-peroxidase (pap) complex procedure resulted in nonspecific staining of the ma ...1977319165
ontogenic development of swine (sus domesticus) adipose tissue lipases.1. the in vitro activities of lipoprotein lipase (lpl) and hormone sensitive lipase (hsl) were examined in adipose tissue preparations from pigs 0-150 days of age. 2. the activities of both lpl and hsl increased 3- to 4-fold between birth and day 2 postpartum, remained at relatively high levels through weaning, and fell sharply in the oldest animals (150 days). 3. the decline in enzyme activities at older ages could partially be attributed to an increase in adipocyte size.1978318233

percutaneous cardiac puncture in domestic pigs.blood sampling by percutaneous cardiac puncture was carried out in 69 domestic pigs. the procedure was shown to be safe and to produce reproducible data. the technique can be carried out without anaesthesia. repeated sampling is possible over minutes, hours or days, and a wide range of sample volumes can be achieved by this technique.1977921641
[in vitro incorporation of (33p)orthophosphate into the erythrocyte membrane phospholipids of newborn and adult domestic pigs].phosphate turnover of erythrocyte membrane phospholipids, judged by [33p] incorporation, was investigated with phosphatidylethanolamine, lecithin, sphingomyelin, phosphatidylserine, phosphatidylinositol, and phosphatidic acid in newborn and adult domestic pigs. a new micromethod is described in detail using between 10(9) to 10(10) cells, both for quantitative determination of phospholipids and tracer incorporation studies in erythrocyte membrane phospholipids. erythrocyte phospholipid values are ...1976998113
14c-glucose and 35s-metabolism of pig epiphysial cartilage and its variations after osteotomy.on in vitro incubation of articular and epiphysial cartilage of the ulna of the domestic pig 70 to 80 per cent of [u-14c] glucose was metabolised to 14c-lactate, but cartilage of the epiphysial plate produced up to five times as much 14c-co2 as articular cartilage, and the specific radioactivity of 14c(or 35s)-chondroitin 4(6)-sulphate isolated from epiphysial cartilage (following 35s-sulphate incorporation) was about twice as high as that of articular cartilage. six weeks after an osteotomy on ...19751194320
[etiology of benign papillary stenoses].in domestic pigs repeated applications of gastrointestinal hormones (pancreozymin, secretin) as well as cholecystectomy lead to histologic transformation of the epithelium in the area of the papilla of vater and to inconstant pressure changes in the common duct.19761031785
investigations of ultrastructure of the adenohypophysis in the domestic pig (sus scrofa domestica). part ii: "dark cells" in the pars anterior.the investigations were done on 34 hypophyses of the pig embryos aged c. 46-79 days of pregnancy. the name "dark cells" was given to one of the type of differentiated cells of the pars anterior which were characterized by intense electron density of the basic cytoplasm. the cells correspond to the "follicular cells" and the "stellate cells" described in many species of adult vertebrates. probably the dark cells have supporting function, as they originate a system of nets and tubular structures w ...1978744536
ontogenesis of enzyme systems deaminating different monoamines.1 a detailed investigation into the postnatal development of the activity of the enzyme monoamine oxidase (mao) in the rat and domestic pig was carried out. 2 mao activity was measured in littermate male rats aged between 3 and 122 days belonging to six breeding colonies. the tissues studied were three brain regions in which monoamines may play a role in neuronal transmission (septum, hypothalamus, corpus striatum) and, for comparison, in the cerebellum. liver, heart and adrenal glands were the ...1976938797

distribution of the dental lamina and deciduous tooth development in the mandible of the domestic pig.specimens of known age, weight, and crown-rump length were used to characterize the distribution of the dental lamina and deciduous tooth development in the mandible of the domestic pig.19751054333
investigation of ultrastructure of the adenohypophysis in the domestic pig (sus scrofa domestica). part iii. capillary vessels of the pars anterior.the investigations were carried out on 34 hypophyses of pig embryo aged c. 46--79 days of fetal life. capillary vessels of the glandular part have the three-layer structure, and this structure is in general similar to the one of the capillaries of adult vertebrates. in the investigated stages of the fetal life the structure undergoes certain modifications; pores with septa (so called fenestra) occur in the cytoplasms of the endothelial cells, microvilli protruding to the lumen of the vessels dis ...1978744537
the gene for dominant white color in the pig is closely linked to alb and pdgrfra on chromosome 8.white is a widespread coat color among domestic pig breeds and is controlled by an autosomal dominant gene i. the segregation of this gene was analyzed in a reference pedigree for gene mapping developed by crossing the european wild pig and a large white domestic breed. the gene for dominant white color was shown to be closely linked to the genes for albumin (alb) and platelet-derived growth factor receptor alpha (pdgfra) on chromosome 8. an unexpected phenotype with patches of colored and white ...19921362182
experimentally induced steroid atrophy in the domestic pig and man.a histological method of ranking topical steroid preparations according to the degree of epidermal thinning they cause in pig skin has been shown to be applicable to human skin. a 0-05% ointment of the new compound, clobetasone butyrate (molivate), has been shown to cause less thinning than either fluocinolone acetonide 0-025% (synalar) or flurandrenolone 0-0125% (haelan) when applied without the use of occlusive dressings for 3 weeks to the human forearm.19761268070
