RESUMO
OBJECTIVE: To study the mechanisim of Yi Qi Tong Lin Chingji in treating benign prostatic hyperplasia. METHOD: The expressions of VEGF, bFGF and TGF beta 1 in prostatic hyperplasia model rats were examined by immunohistochemistry. 8 rats were in contrastive group, 24 influenced by Yi Qi Tong Ling Chingji and Prostacar. RESULT: The expressions of VEGF and bFGF were significantly difference, but the expression of TGF beta 1 was not significant. (P < 0.01). The expression of VEGF and bFGF were significant in contrastive group to the high-dose of Yi Qi Tong Ling Chingji and Prostacar group (P < 0.05) but were not significant to the low-dose of Yi Qi Tong Ling Chingji group. There was no significant difference between high-dose of Yi Qi Tong Ling Chingji and Prostacar group and three growth factors. CONCLUSION: Yi Qi Tong Ling Chingji inhibit the expression of VEGF and bFGF in BPH so as to decrease the volume of prostate.
