The reversibility of the effect of gossypol on testicular histology and fertility was studied in rats. Adult males of proven fertility were treated orally with gossypol acetic acid (15 mg/kg) for 9 or 16 weeks (groups 1 and 2, respectively). Another groups of animals (group 3) was given gossypol (15
The late stage of dry age-related macular degeneration (AMD), or geographic atrophy (GA), is characterized by extensive retinal pigment epithelial (RPE) cell death, and a cure is not available currently. We have recently demonstrated that RPE cells die from necrosis in response to oxidative stress,
To determine the effects of gossypol, a male antifertility drug, on the eyefluke, P. gralli, this chemical was administered orally to chickens in long-term and short-term regimens. Gossypol acetic acid (GAA), fed to juvenile chickens from 1 to 35 days, caused a decreased weight gain when compared to
Conventionally housed 130-160 g adult male Japanese quail were given gossypol acetic acid (gossypol) im at 25 mg/kg in 0.5 ml of 10% EtOH for 12 and 24 days (Groups 1 and 2), respectively. One day after treatment was terminated they were allowed to mate with laying females individually for 20 days.
Gossypol acetic acid (GAA) displays anti-fertility and antioxidant behavior. The efficacies of different doses of gossypol acetic acid were investigated in male albino rats. Rats were allocated into four groups: control group and three GAA-treated groups (2-4), that were injected with GAA (5, 10,
The effect of gossypol on thyroid structure and function was examined. Groups of young male rats were subcutaneously injected daily with 0.2 ml gossypol acetic acid in doses of 1, 5, or 10 mg per kg body weight. Control rats were injected with vehicle only. At the end of the 15-day treatment, there
Adult male Wister rats when administered with 15 mg/kg body weight/day of gossypol acetic acid proved to be sterile by 10 weeks of treatment. The weight of the whole epididymis did not deviate from the controls but when the caput, corpus and cauda epididymidis were considered separately, the cauda
Reversible male antifertility activity was obtained with orally administered gossypol acetic acid in rats at 20 mg/kg/day and in hamsters at 10 mg/kg/day but not in mice at dosages up to 40 mg/kg/day. An increased number of degenerating spermatocytes was found in the testicular tubular lumens of
Gossypol treatment of endometriosis and uterine myomas in 15 cases was started with a daily dose of 20 mg of gossypol-acetic acid twice a day for 20 days as a loading dose, followed by 40 mg (20 mg twice weekly). A maintenance dose of 20 mg was given weekly. The total course of treatment lasted
The effects of gossypol acetic acid (GAA) were compared with those induced by estradiol-17 beta (E2), testosterone, and a combination of these steroids. GAA was administered s.c. to adult rats at doses of 25 to 30 mg . kg BW . day for 30 days, while steroids in polydimethylsiloxane tubing of various
