Alkaline Phosphatase Activity in the Rat Uterus1

Alkaline phosphatase activity in the rat uterus.

A COMPARATIVE study of the distribution of placental scars from the first and second pregnancies in laboratory rats indicated that the most posterior scar of first pregnancy tends to be nearer to the cervix than the most posterior second pregnancy scar (Momberg & Conaway, 1956). Frazer (1955) in an earlier study observed that more embryos implanted in the caudal half of the uterus of the rat th...

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...

Cholesterol modulates alkaline phosphatase activity of rat intestinal microvillus membranes.

Experiments were conducted, using a nonspecific lipid transfer protein, to vary the cholesterol/phospholipid molar ratio of rat proximal small intestinal microvillus membranes in order to assess the possible role of cholesterol in modulating enzymatic activities of this plasma membrane. Cholesterol/phospholipid molar ratios from 0.71 to 1.30 were produced from a normal value of 1.05 by incubati...

Functional interrelationships in the alkaline phosphatase superfamily: phosphodiesterase activity of Escherichia coli alkaline phosphatase.

Escherichia coli alkaline phosphatase (AP) is a proficient phosphomonoesterase with two Zn(2+) ions in its active site. Sequence homology suggests a distant evolutionary relationship between AP and alkaline phosphodiesterase/nucleotide pyrophosphatase, with conservation of the catalytic metal ions. Furthermore, many other phosphodiesterases, although not evolutionarily related, have a similar a...
