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
