[Quantitative histochemical study of alkaline phosphatase isoenzymes in the uteri of ovariectomized golden hamsters during estrogenization].

The activity of two isoenzymes of alkaline phosphatase was studied in the uteri of ovariectomized golden hamsters. Animals belonging to different groups were daily injected with 10 micrograms of estrogen (octoestrol) once, for 4 and 16 days. The estrogen did not affect the overall activity lf alkaline phosphatase in the uterine luminal epithelium, but decreased the enzyme activity in stroma. Moreover, it was found that prolonged estrogen treatment increases significantly the proportion of alkaline phosphatase isoenzyme of the intestinal type in the uterine luminal epithelium.
