目的 :研究吸烟对雄性大鼠性功能影响状况。 方法 :用人工呼吸器造成大鼠被动吸烟 ,测定大鼠尿、血、睾丸组织镉 (Cd)含量 ,T、LH值及观察酶组织化学 β SHDH变化 ,睾丸病理改变 ,阴茎海绵体变化。 结果 :实验组血、尿、睾丸Cd值高于正常对照组 ,而T、LH值和 β SHDH酶低于正常对照组。实验组睾丸组织水肿、瘀血、炎性改变 ,电镜观察到阴茎海绵体血管壁增厚。 结论 :吸烟引起大鼠性功能降低。
Objective: To study the effect of smoking on the sexual function of male rats. Methods: Passive smoking was induced in rats by artificial respirator. Cadmium (Cd), T, LH and histochemical changes of β SHDH in the urine, blood and testis of rats were determined. Pathological changes of the testis and changes of the penis were observed. Results: The Cd of blood, urine and testis in the experimental group was higher than that in the normal control group, while the T, LH and β SHDH enzymes were lower than those in the normal control group. The testicular tissue edema, blood stasis and inflammatory changes were observed in experimental group. The thickening of blood vessel wall of penis was observed by electron microscope. Conclusions: Smoking causes decreased sexual function in rats.
