Abstrakt: The hypocholesterolemic activity of a number of natural and synthetic steroids was determined in a 3-day oral assay using male rats with hypercholesterolemia of dietary origin. The reduction in serum cholesterol was linearly related to the log dose of the administered natural or modified estrogen; the effect was evident 6hr. after oral administration and had reached a maximum in 24 to 30hr. Active steroids lowered the elevated serum phospholipids, cholesterol/phospholipid ratios, triglycerides, αand βlipoproteins, and β/αlipoprotein ratios, but not the elevated serum globulins. The effect of the steroids on body weight permitted a semiquantitative estimation of feminizing activity.
