以剂量为１００ｍｇ／ｋｇ体重、５００ｍｇ／ｋｇ体重的硝基苯（ＮＢ）分别给雄性小白鼠经口染毒。染毒２天后，各染毒组的睾丸组织中Ｇ－６－ＰＤ、ＬＤＨ－ｘ、ＳＤＨ的活性均明显低于对照组。染毒４天后，染毒组Ｇ－６－ＰＤ活性恢复到对照水平；ＬＤＨ－ｘ的１００ｍｇ／ｋｇ体重组恢复到对照水平，而５００ｍｇ／ｋｇ组仍明显低于对照组；ＳＤＨ活性染毒组仍低于对照组。ＬＰＯ值在染毒２天、４天后与对照组相比均无显著差异。
Male mice were orally exposed to nitrobenzene (NB) at a dose of 100 mg / kg body weight and 500 mg / kg body weight, respectively. After 2 days of exposure, the activity of G-6-PD, LDH-x, and SDH in testis tissue of each exposure group was significantly lower than that of the control group. After 4 days of exposure, the activity of G-6-PD in the exposed groups returned to the control level; the 100 mg / kg body weight of LDH-x returned to the control level, while the 500 mg / kg group was still significantly lower than the control group; Still lower than the control group. There was no significant difference in LPO between two days and four days after exposure.
