Comparative properties of high potassium and low potassium sheep erythrocyte membrane sodium-activated adenosine triphosphatase.
A comparative study of the Na+-stimulated adenosine triphosphatase system in high potassium (HK) and low potassium (LK) sheep red cell membranes was carried out. For HK:LK activity, the approximate ratios were as follows: 10 for Na+-ATPase, 13 for Na+, K+-ATPase, and 2.7 for [%+ ADP-ATP exchange activity; the ratio of Na+-stimulated membrane phosphorylation was approximately 7. With Na+ present...
متن کاملAssociation of the whole blood potassium polymorphism with resistant to saline in two sheep breeds of different climates of Iran
Abstract The whole blood potassium concentration has shown the bimodal distribution in sheep, which has been classified into LK and HK types; HK allele is recessive to LK with a single gene inheritance. This polymorphism showed different behavior in different environment, which could be due to adaptation process. This research was conducted on the Zel and kermani breed research station, which...
متن کاملThe potential of bacteria isolated from ruminal contents of seaweed-eating North Ronaldsay sheep to hydrolyse seaweed components and produce methane by anaerobic digestion in vitro
The production of methane biofuel from seaweeds is limited by the hydrolysis of polysaccharides. The rumen microbiota of seaweed-eating North Ronaldsay sheep was studied for polysaccharidic bacterial isolates degrading brown-seaweed polysaccharides. Only nine isolates out of 65 utilized >90% of the polysaccharide they were isolated on. The nine isolates (eight Prevotella spp. and one Clostridiu...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Changes in erythrocyte potassium concentration in Goldblatt hypertension of the rabbit.
Changes in potassium (K) concentration in erythrocytes (RBC) were investigated during the early developing stage (1 and 2 weeks after) and the chronic established stage (12 to 16 weeks after the renal artery constriction) in two-kidney (group 2H) and one-kidney Goldblatt hypertension (group 1H) of the rabbit. In both group 2H and group 1H, blood pressure was already elevated significantly durin...
