摘 要:目的探讨氟硒及其联合作用对雄性大鼠生殖的影响。方法将64只Wistar大鼠随机分为四组:氟、硒、氟+硒及对照组;染毒3个月后处死动物,测定睾丸组织γ-GT、SDH活性和MDA含量;并计精子总数、存活率和畸形率等。结果实验和对照组动物睾丸重量、横径及脏器系数经统计学处理无显著意义;3ppm的亚硒酸钠可使γ-GT活性明显升高,SDH活性显著下降,与MDA水平升高结果相符;50ppm的氟化钠可使精子总数减少、存活率降低。当两者联合作用时,上述作用均有不同程度的减轻。结论采用安全剂量的氟或硒,可减轻慢性硒或氟中毒对雄性大鼠生殖系统的影响。Objective For studying the effects of fluoride and selenium on reproductive system of male rats. Motheds 64 male Wistar rats were randomly divided into 4 groups:NaF group,Na2SeO3(Se)group,NaF+Se group and control group.All the experimental animals were treated with the chemicals respectively for 3 months,then the activities of γglutamyltranferase(γGT),sorbitol dehydrogenase(SDH) in testicles tissues,the content of malonic dialdehyde(MDA),the amount,mortality and abnomality rate etc were determined. Results The results showed that there were no significant differences in testicles weights and diameters,in organ coefficient between experimental animals and controls.But there was an increase in activity of γGT and content of MDA and a decrease in activity of SDH in the group of 3ppm Se,and there was a remarkable decrease in amount of sperm in the group of 50 ppm NaF.However,all the above effects were weakened by combined administering of fluoride and selenium. Conclusions It is suggested that the safe dosage of fluoride or selenium respectively,may prevented the harmful effect on male reproductive system from chronic poisoning of selenium or fluoride.
