Objective: To investigate the effects of Yangyin Shugan granule(YYSG) on ovarian function in rats with diminished ovarian function
and explore its effect on B-cell lymphoma-2 (Bcl-2)
Bcl-2 associated X protein (Bax)
and cysteine-aspartic acid protease-3(Caspase-3) protein expression.Method: SD female rats with estrous cycle rules were selected
10 used as blank group
and the others were used to establish diminished ovarian function model by injecting 160 mg·kg-1 4-vinylcyclohexenediepoxide (VCD) into enterocoelia. 56 model rats with diminished ovarian function were randomly divided into 5 groups:model group
low-
middle-
high-dosage YYSG groups
and Kuntai capsule group
n=11 on each group (n=12 in model group). The YYSG groups (2.1
4.2
8.4 g·kg-1) and Kuntai capsule group had intragastric administration for 4 weeks after the model establishment. Then the ovarian weight was measured and follicle count was calculated. The levels of serum sex hormones[follicule-stimulating hormone (FSH)
estradiol (E2)
and anti-mullerian hormone (AMH)] were detected by enzyme-linked immunosorbent assay (ELISA). The expression levels of Bcl-2
Bax
Caspase-3 in ovarian tissue were detected by Western blot.Result: As compared with the normal group
the ovary weight and ovary index were decreased (P<0.01)
Atresia follicle count was decreased (P<0.01)
FSH level was increased (P<0.01)
E2 and AMH levels were decreased (P<0.05)
Bcl-2 protein expressions were decreased (P<0.01)
and Bax and Caspase-3 protein expressions were increased(P<0.01) in model group. As compared with the model group
the ovary weights of YYSG groups were increased(P<0.05
P<0.01); YYSG granule and Kuntai capsule could increase the ovarian index(P<0.05
P<0.01); YYSG granule could reduce the numbers of atresia follicles(P<0.05); YYSG granule and Kuntai capsule could decrease FSH level but increase E2 and AMH levels(P<0.05)
increase the expression of Bcl-2 protein(P<0.01)
and decrease the expression levels of Bax
Caspase-3 protein(P<0.01).Conclusion: YYSG could improve the ovarian function of rats with diminished ovarian function and the mechanisms may be associated with anti-apoptosis.
