Abstract:
Objective:To study the effects of the Gekko gecko ethanol extract on granular cells apoptosis of rat ovaries.Methods :3 month and 6 month female Wistar rats were taken in this study, and 20 rats were in each age group.Each age group were randomly divided into two groups(experimental group and control tragastric administration in experimental group, corresponding volume of 0.9% sodium chloride was given in control group by the same way.Apoptosis of granular cells and distribution of cell cycle in rat ovary were measured by terminal-deoxynucleotidyl transferase mediated d-UTP nick end labeling (TUNEL) and propidi-um iodide(PI) staining, AnnexinV/PI double labelling staining by flow cytometry (FCM) after administration for 15 days.Re8utts:The apoptosis numbers of granular cells in 3 month and 6 month age experimental group were 34 ±7 and 53 ±11, in control group were 48±9 and 76±17 respectively by TUNEL.There was signrficantly statistic difference (P <0.01).The apoptosis rates in 3 month and 6 month age experimental group were(6.06 ±2.01)% and (12.16 ±3.26) % , in the control group were (8.23±2.13) % and (23.69 ±6.28)% respectively by PI staining.There was significantly statistic drfference (P <0.05).However, no significant difference was found between two groups in cellular cycle distribution (P > 0.05).Early apoptosis rates in 3 month and 6 month age experimental group were (6.71±3.11) % and (23.74±6.28) % , in the control group were (19.05 ±5.78) % and (36.55± 8.35) % respectively by AnnexinV/PI double labelling staining FCM.There was significantly statistic difference (P <0.01).The apoptosis of granular cells were sig-nificantly less in experimental groups comparing wrth control groups both in 3 month and 6 month age group (P<0.01 or P<0.05).Conclusions :The ethanol extract of gekko gecko can inhibit the apoptosis of granu-lar cells in rat ovary, then improves the ovary function and delay ageing of rat.
