title: [Alkaline phosphatase activity and properties in the organs of cattle and sheep].
abstract: Alkaline-phosphatase activity and the physico-chemical properties of the liver, lung, spleen, kidney, intestine, bone and placenta of 25 clinically healthy cattle and 30 clinically healthy sheep were investigated. High alkaline phosphatase activity was detected in kidneys and intestines. The alcaline phosphatase of cattle and sheep liver, spleen, kidney, lung, bone and placenta was thermo-labile and sensitive to l-arginine, l-homoarginine and imidazole, but was not sensitive to l-phenylalanine. Bone phosphatase of cattle and sheep was sensitive to urea. Intestinal phosphatase of cattle proved thermostable, sensitive to l-phenylalanine and not sensitive to l-arginine, l-homoarginine, imidasol and urea. Agarose gel electrophoresis of alkaline phosphatase indicated the presence of one fraction only and liver alkaline phosphatase proved to be the fastest. Sheep liver alkaline phosphatase had two fractions while sheep intestinal and placental alkaline phosphatase had three fractions and some of them were faster than liver alkaline phosphatase.
