Cím:	Effects of anandamide (endogen cannabinoid) on anterior pituitary hormone secretion in adult ovariectomized rats / Wenger T., Tóth B. E., Martin B. R.
Dátum:	1995

Megjegyzések:	It has been shown that the main psychoactive component of marihuana, delta 9-tetrahydrocannabinol (THC) has mainly inhibitory effects on pituitary luteinizing hormone (LH), prolactin (PRL) and growth hormone (GH) and has no or little effect on follicle stimulating hormone (FSH) secretion. Recently the purification and availability of the putative endogenous ligand for the cannabinoid receptor, anandamide (arachidonyl ethanol-amide, anandamide) (ANA) provided us the opportunity to compare the effects of THC and ANA on the female neuroendocrine system in ovariectomized (OVX) rats. OVX was performed three weeks prior to the experimental period to avoid cyclic differences. OVX rats were injected i.p. with either THC or ANA (0.02 mg/kg.b.w./day, respectively) or vehicle for two weeks. The results show that both ANA and THC decrease serum LH level although THC with a higher degree. No significant differences were observed in serum FSH level. Both drugs decreased serum PRL. Serum GH was increased after THC administration and significantly decreased after ANA. The results indicate that ANA and THC alter pituitary hormone secretion, mainly by inhibitory action. The site of action requires further investigations.
