| Abstract: | Activity of oxidative enzymes in the epithelium lining the uterine cavity and in the glandular epithelium of ovariectomized rats in the period of climacteric disorders was investigated by a comparative microphotometric method. An increase in lactate dehydrogenase (LD) and glucose-6-phosphate dehydrogenase (G6PD) activity and a decrease in succinate dehydrogenase (SD) and NAD- and NADP-diaphorase activity were found in the epithelial cells lining the uterine cavity. LD activity was increased in the glandular epithelium but SD, and NAD- and NADP-diaphorase activity was sharply reduced. Injection of testosterone propionate caused a marked increase in the activity of the oxidative enzymes studied in the endometrial epithelium of the rats compared with their activity in control rats and in rats not receiving the hormone.Research Institute of Human Morphology, Academy of Medical Sciences of the USSR, Moscow.
