چکیده

Electrophoresis of some serum samples on polyacrylamide gel, followed by staining for alkaline phosphatase (EC 3.1.3.1), produces a band of activity at the gel origin. This high-Mr band consists of liver membrane fragments containing alkaline phosphatase and other enzymes. Alkaline phosphatase is closely associated with phosphatidylinositol in liver plasma membranes, and we have found that phospholipase C (EC 3.1.4.3) from Bacillus cereus, known to possess some phosphatidylinositol specificity, was able to release liver alkaline phosphatase from the high-Mr band. Two preparations of phospholipase C from Clostridium perfringens, however, which has no phosphatidylinositol specificity, had no effect on the alkaline phosphatase activity in the high-Mr band.

Effect of albumin on results of an "improved" analog-type assay for free thyroxin.

The paper by Sykes et al. (1) on the effect of phospholipase C on high-molecular-mass alkaline phosphatase in serum contains nomenclatural errors. In the Abstract, an Enzyme Comnussion number (EC 3.1.4.3) is given for the phospholipase C of Bacillus cereus; this is not the Enzyme Commission number of the phospholipase C responsible for the effect reported (i.e., the release of liver alkaline ph...

The 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...

High-molecular-mass alkaline phosphatase in serum and bile: nature and relationship with lipoprotein-X.

Using immunoelectrophoresis and other techniques, we have demonstrated an association between lipoprotein-X and (a) alkaline phosphatase and (b) other enzymes originating from the hepatocyte membrane, namely gamma-glutamyltransferase and leucine aminopeptidase. The high-molecular-mass forms of these enzymes, in both serum and bile, were precipitated by lipoprotein-X antiserum but not by antiser...

Background: Studies show that aerobic exercise prevents osteoporosis in menopause by stimulating osteoblastic cells. Therefore, the purpose of this study was to investigate the effect of 12 weeks of moderate-intensity aerobic exercise on alkaline phosphatase gene expression, serum levels of alkaline phosphatase, parathyroid hormone, and calcium in sedentary women. Methods: T...
