Abstract
BACKGROUND
Picralima nitida seed extract (PNE) has aphrodisiac and contraceptive effect.
AIM
To investigate the effect of PNE on reproductive hormones.
MATERIALS AND METHODS
The size and length of the combs of white leghorn day-old chicks treated with testosterone (0.5-1.5 mg/kg), cyproterone (3-30 mg/kg), or PNE (50-500 mg/kg) for 7 days, as well as cyproterone (10, and 30 mg/kg) on PNE-induced, and PNE (50-500 mg/kg) on testosterone-induced comb growth, were measured in the chick comb test. The effect of PNE the percentage change in an oviduct-chick weight ratio of Rhode Island Red layer day-old chicks treated with 17-β-estradiol (0.1-0.9 µg), PNE (30-300 mg/kg) or vehicle, for 6 days, was determined in the chick uterotrophic assay. Liver and kidney function was well lipid, and hematological profile tests were conducted to assess safety.
RESULTS
7-day treatment with PNE and testosterone increased significantly (P ≤ 0.01-0.001) while cyproterone significantly decreased (P ≤ 0.001) comb growth dose-dependently. Qualitatively, testosterone and PNE treatment resulted in relatively brighter red combs. Cyproterone caused significant inhibition (P ≤ 0.001) of both testosterone and PNE-induced comb growth. Co-administration of testosterone and PNE suppressed comb growth significantly (P ≤ 0.001). Administration of 17-β estradiol and PNE increased (P ≤ 0.001) oviduct-chick weight ratio dose-dependently. No significant changes were observed in assessing liver and kidney function, lipid profile, and hematological parameters.
CONCLUSION
PNE exhibits both androgenic (partial testosterone agonist) and estrogenic activity. It has no detrimental effects on the blood, liver, and kidney tissue with prolonged use.
