探讨混苯对接触男工精子顶体酶活力和副性腺功能的影响，对２３名从事混苯作业的男工进行生物材料混苯分析及精子顶体酶活力、精浆γ－ＧＴ活性和果糖含量的测定。结果接触组顶体酶活力、精浆γ－ＧＴ活性和果糖含量分别为１８．０２±７．２４Ｕ／Ｌ、１７１４．４３±８７３．８８Ｕ／Ｌ、３．０９±２．０５ｇ／Ｌ，而对照组则分别为３０．７４±１０．０５Ｕ／Ｌ、２４１８．９７±４１１．９２Ｕ／Ｌ、２．０３±０．７４ｇ／Ｌ。表明混苯可引起男工精子顶体酶活力下降（Ｐ＜０．００１），精浆γ－ＧＴ活性显著低于对照组（Ｐ＜０．０５），而精浆果糖含量两组间未见差别。精子顶体酶活力与接触工龄、精浆γ－ＧＴ与精浆中苯及血液中甲苯等呈负相关。混苯在一定程度上可影响男工生育力和副性腺功能。
To investigate the effect of mixed benzene on sperm acrosin activity and para-gonadal function in male sperm, 23 male workers who mixed benzene were analyzed for benzene mixed material and sperm acrosin activity, seminal plasma γ-GT activity and fructose Determination of content. Results The acrosin activity, the activity of seminal plasma γ-GT and the content of fructose were respectively 18.02 ± 7.24U / L, 1714.43 ± 873.88U / L and 3.09 ± 2.05g / L in the contact group The control group was 30.74 ± 10.05U / L, 2418.97 ± 411.92U / L and 2.03 ± 0.74g / L, respectively. (P <0.001), but the γ-GT activity of seminal plasma was significantly lower than that of the control group (P <0.05), while the fructose content of seminal plasma did not show any significant difference between the two groups difference. Sperm acrosin activity and contact length of service, seminal plasma γ-GT and seminal plasma benzene and blood toluene was negatively correlated. Mixed benzene to a certain extent, can affect male fertility and vice gonadal function.
