Objective: To explore the mechanism of acupuncture for treatment of perimenopausal syndrome.
Methods: The rats of perimenopausal syndrome were randomly divided into 3 groups, including an acupuncture group treated with acupuncture, a medication group with Gengnian'an, and a perimenopausal control group, with young rats used for a control group. Granulocyte apoptosis and expressions of Bcl-2 and Fas proteins in the ovary of the rat were detected.
Results: Granulocyte apoptosis increased significantly (P < 0.01), expression of Bl-2 proteins decreased significantly (P < 0.01) and expression of Fas proteins increased significantly (P < 0.01) in the ovary of perimenopausal rats as compared with the young rats; after acupuncture treatment, granulocyte apoptosis decreased significantly (P < 0.05), expression of Bel-2 proteins increased significantly (P < 0.05) and expression of Fas proteins decreased significantly (P < 0.01); after treatment of Gengnian'an, granulocyte apoptosis did not significantly change (P > 0.05), expression of Bcl-2 prteins increased significantly (P < 0.05) and expression of Fas proteins decreased significantly (P < 0.01).
Conclusion: Acupuncture can inhibit granulocyte apoptosis, up-regulate expression of Bcl-2 proteins and down-regulate expression of Fas proteins in the ovary of the perimenopausal rat.
