Synergistic effects of probucol and cholestyramine to lower serum cholesterol.

Ten men with hypercholesterolemia were treated sequentially with a fat-modified diet, a diet plus probucol (1 Gm/day), and a diet plus probucol plus cholestyramine (16 Gm/day). Each treatment period was 12 weeks. Diet alone reduced mean serum cholesterol by 1.0 per cent. Diet plus probucol caused a mean 7.7 per cent reduction in serum cholesterol below the baseline values (P = 0.001 compared to diet). Adding cholestyramine to probucol and diet resulted in a mean 18.2 per cent reduction in serum cholesterol below baseline values (P = 0.001 compared to probucol and diet). The treatment was well tolerated.

High density lipoprotein cholesterol and body composition of female runners.

Twenty-two women participating in an endurance running program had determinations of body composition, of plasma total cholesterol (TC) and HDL cholesterol (HDLC) concentrations before and after increasing their running by 30 miles/wk. Mean total body weight, fat weight and relative body fat showed significant decreases, while mean lean weight significantly increased. Mean HDLC increased 5 mg/dl (p less than 0.01). Although increases of HDLC correlated with increases in lean weight, exercise per se appears to increase HDLC of women.

Chronic ethanol ingestion enhances GnRH-stimulated LH responses of castrated male dogs.

Dogs were given no ethanol, 1.28 g ethanol/kg and 1.92 g ethanol/kg daily for 4 weeks immediately after castration. Plasma LH concentrations, basal and in response to 100 micrograms GnRH, were measured before and at 2 and 4 weeks after castration. Basal LH levels after castration increased significantly (P less than 0.005) within each group but were not significantly different between groups. GnRH-stimulated LH responses were similar before and at 23 weeks after castration, but at 4 weeks the dogs given 1.92 g ethanol/kg had a significantly (P less than 0.05) greater response than did the control dogs. It is concluded that daily ethanol ingestion in the amounts employed in this study does not impair hypothalamic--pituitary function in male dogs.

Reserpine, hydrochlorothiazide and pituitary-gonadal hormones in hypertensive patients.

Sex histories and serum samples were obtained from 27 hypertensive men before and after 3 months of therapy with either 100 mg of hydrochlorothiazide or 0.25 mg of reserpine daily. Sera were analyzed for testosterone, dihydrotestosterone, estradiol, luteinizing hormone and prolactin. Both drugs effectively lowered pressure. The incidence of impaired sexual performance was low and insignificantly different in the two treatment groups. There were no significant changes in serum hormone concentrations as a result of drug therapy.

Testosterone secretion by the isolated canine testis after controlled infusions of HCG.

A technique is described for perfusion of isolated canine testes. Infusing the testes with various amounts of hCG identified a rate of 0.075 i.u./min as one which reliably increased testosterone secretion into the spermatic venous effluent without producing maximal testosterone production.
