title: Comparative study of the effects of beta-sitosterol, estradiol and progesterone on selected biochemical parameters of the uterus of ovariectomised rats.
abstract: A comparative study was made of the effects of beta-sitosterol, estradiol-17 beta and progesterone, individually and in combinations, on certain biochemical parameters important to carbohydrate metabolism in the uteri of adult ovariectomised rats. beta-Sitosterol (SITO), estradiol (E2) and combined treatment (SITO + E2) induced significant increases in glycogen concentration and the activities of glucose-6-phosphate dehydrogenase (G6PDH), phosphohexose isomerase (PHI) and total lactate dehydrogenase (LDH). Progesterone (P) administration however, raised only the uterine PHI and LDH activities. Co-administration of P with beta-sitosterol (P + SITO) suppressed the SITO-induced increase in glycogen concentration and G6PDH activity. On the other hand, combined treatment (P + SITO) augmented total LDH activity.
