Effect of beta-sitosterol on uterine biochemistry: a comparative study with estradiol and progesterone.

Abstract

Administration of estradiol/progesterone to ovariectomized animals significantly increased the uterine weight, RNA, DNA and protein concentrations. Similarly, administration of beta-sitosterol alone or in combination with estradiol caused a marked increase in the above parameters and the maximum influence was evident only after median and high dose treatments. However, administration of median/high dose of beta-sitosterol along with progesterone accentuated only the RNA and protein concentrations but exerted an inhibitory effect on sitosterol-induced increment in uterine weight and DNA concentrations.
