RESUMO
Objective To observe the effects ofJingui Shenqi Pills on the expressions of TGF-β1, CYP19, sex hormone level and sperm quality;To discuss its mechanism for the treatment of male sterility.Methods Forty adult male SD rats were randomly divided into normal group, model group, retardant group andJingui Shenqi Pills group, 10 rats in each group. Except for the normal group, adenine was used to induce healthy rats to kidney yang deficiency and sterility model rats. Normal group was given normal saline for gavage;retardant group was injected with testicular mesenchyme TGF-β1;Jingui Shenqi Pills group was givenJingui Shenqi Decoction for gavage. Blood was taken through caudal vein. Immunohistochemical, radioimmunoassay and electron microscopy observation were used to detect the expressions of TGF-β1, CYP19, sex hormone level, sperm density and motility rate and testicular morphological changes.Results Compared with normal group, the expression of TGF-β1 in the model group increased and CYP19 decreased (P<0.05). Compared with model group, the expression of TGF-β1 decreased and the expression of CYP19 increased (P<0.05). Compared with normal group, the number of sperm quantity was small and paramorphia in model group (P<0.05). Compared with model group, T, E2, sperm density and motility rate increased significantly inJingui Shenqi Pills group and retardant group (P<0.05). There was no statistical significance among indexes in retardant group andJingui Shenqi Pills group.ConclusionJingui Shenqi Pills can improve sperm quality and sex hormone level of model rats with kidney-yang-deficiency, which mechanism is probably realized by inhibiting the expression of TGF-β1R and promoting the expression of CYP19 in testis to effect development and proliferation of sperm.
