摘要
为探讨镉对附性腺和睾丸细胞的影响 ,采用WHO推荐的方法 ,测定镉接触工人精浆果糖和精浆转铁蛋白 ,结果 ,接触组的果糖和转铁蛋白含量均显著低于对照组 (P <0 0 5 ,P <0 0 1) ,但不同血镉浓度组间的果糖和转铁蛋白含量无明显差异。随着精浆镉浓度的升高 ,精浆果糖含量有下降趋势 (P >0 0 5 ) ,而精浆转铁蛋白含量则显著降低 (P <0 0 5 )。精浆转铁蛋白含量随着接镉工龄的延长显著降低 (P <0 0 1) ,而精浆果糖含量各工龄组间无明显差异。相关分析表明 ,精浆果糖、转铁蛋白含量与精子畸形率呈显著负相关。
To study the effects of cadmium on frucose and transferrin in seminalplasma from occupationally exposed workers, the general conditions of workers were investigated with the questionnaire. The determination of frucose was carried out using the methods that WHO recommended, and transferyin was assayed by using kit.The results showed that the amount of fructose and transferrin was significantly lower in the exposed group than that in the control group (P<0.05, P<0.01), but no significant difference was found in the content of fructose and transferrin anlong different blood cadmium groups. There was a decreasing trend of the concentrations of fructose and transferrin as the increase of seminal plasma cadmium concentration.The content of transferrin in seminal plasma was reduced significantly by prolonged cadmium exposure period (P<0.01), but the content of ructose among different cadmium exposure period showed no significant difference. Comelation analysis indicated that a negatively conelative relationship between the fmctose, transferrin in the seminal plasma and the rate of malformation sperm (P<0.05).These findings suggested that the secretive functions of the testicular cell can be affected by occupational cadmium exposure.
