桂枝茯苓胶囊对实验性大鼠前列腺增生的影响

目的观察桂枝茯苓胶囊对丙酸睾丸素致大鼠前列腺增生症的影响。方法大鼠去睾丸7d后,sc丙酸睾丸素(3mg/kg)建立大鼠前列腺增生症病理模型,同时连续ig桂枝茯苓胶囊(2.16、1.08、0.54g/kg)30d,末次给药后1h,处死动物,取前列腺称质量,测定体积并进行病理学检查。结果桂枝茯苓胶囊给药组大鼠前列腺质量和体积均低于模型组(P<0.05,0.01);病理镜检显示桂枝茯苓胶囊给药组前列腺腺腔组织扩张较轻,且增生腺上皮高度较模型组低,尤以大、中剂量组最为明显(P<0.05,0.01)。结论桂枝茯苓胶囊可明显抑制大鼠前列腺组织增生。

Effects of Guizhi Fuling Capsule on prostatic hyperplasia in experimental rats

Object To observe the effect of Guizhi Fuling Capsule (GFC) on prostatic hyperplasia in rats induced by testosterone propionate. Methods Seven days after the male rats were castrated, testosterone propionate (3 mg/kg) was sc injected in rats. Meanwhile, the rats were administered GFC (2.16, 1.08, 0.54 g/kg) once a day, and the treatment continued for 30 d. An hour after the final administration, the rats were put to death, and the weight and volume of prostates were measured. The construction of prostate cells was also observed under light microscope. Results In the GFC group, the weight and volume of prostate was significantly decreased compared with that in the model group (P<0 05, 0.01). The atrophy of the prostatic gland was found under the microscope in the GFC group (P<0 05, 0.01). The epithelial cell height was lower than model group, with the significance of large and middle dose groups. Conclusion GFC can inhibit prostatic hyperplasia in rats significantly.
