Phosphatase activity in the ocular tissues.
This specific phosphatase is a 5-nucleotidase; it differs from the alkaline phosphatase in its range of action and in its optimal pH. Whereas alkaline phosphatase, which is non-specific, hydrolyses a great variety of phosphoric esters, the 5-nucleotidase hydrolyses only nucleotides with the phosphate group attached to the fifth carbon of the pentose, that is, muscle adenylic acid (adenosine-5-m...
متن کاملLymphocyte-stimulating activity of ocular tissues in sympathetic ophthalmia.
Blastogenic activity of ocular tissue extracts was elicited in lymphocyte cultures from peripheral blood of two of four patients with sympathetic ophthalmia. Retinal pigment epithelium, retina, and lens were mitogenic, while choroidal antigen was usually inactive. There was no evidence of cellular hypersensitivity to ocular tissue in several other forms of uveitis. The problems in interpreting ...
متن کاملResidual deformations in ocular tissues.
Residual deformations strongly influence the local biomechanical environment in a number of connective tissues. The sclera is known to be biomechanically important in healthy and diseased eyes, such as in glaucoma. Here, we study the residual deformations of the sclera, as well as the adjacent choroid and retina. Using freshly harvested porcine eyes, we developed two approaches of quantifying r...
متن کاملThe effects of chromium and cadmium on the activity of alkaline phosphatase lsoenzmes in rats
The aim of this study was to Investigate the toxic effects of chromium and cadmium on the activity of two isoenzymes of alkaline phosphatase in vitro and in vivo experiments. Oral administration and peritoneal injection of CdCl2 or CrCl3 in rats reduced serum alkaline phosphatase by 21.5℅ and 25.5℅ respectively. At the same time high molecular weight alkaline phosphatase was elevated by 138℅ a...
متن کاملSome factors involved in the effect of x-irradiation on the phosphatase activity of hematopoietic tissues.
By EDWIN M. UYEKI AND PAUL R. SALERNO A NUMBER of enzymes from hematopoietic tissues have been studied with respect to their altered activities after exposure to x-irradiation. Among the enzymes found to be significantly different in x-irradiated animals are adenosine triphosphatase,1 5-nucieotidase1 and adenylate kinase.2 Concomitant with the changes in phosphatases, a decrease in the adenosin...
