呋喃丹对大鼠睾丸组织标志酶活性影响的动态观察

为探讨农药呋喃丹对雄性大鼠睾丸组织的损害作用 ,以低、中、高剂量 (0 3、1 5和 3 0mg kgBW)经口连续染毒 77天 ,分别于染毒第 7、35和 77天检测大鼠血清及睾丸组织匀浆中 β-葡萄糖苷酶 (β-G)、葡萄糖 - 6 -磷酸脱氢酶 (G - 6 -PD)、乳酸脱氢酶同工酶X(LDHx、)的活性。结果显示 ,染毒第 7天大鼠 3个染毒组血清中 β -G活性显著低于对照组 (P <0 0 5) ,低剂量组睾丸组织匀浆中 β -G活性高于对照组、而高剂量组低于对照组 (P <0 0 5) ;染毒第 77天中高剂量组血清中G - 6 -PD活性 ,高剂量组睾丸组织匀浆中LDHx活性均低于对照组 (P <0 0 5) ,其它指标及时段未见明显改变。提示呋喃丹对大鼠睾丸组织有一定损害作用。

Dynamic observation of carbofuran on symbolic enzymes in testis of rats

To examine the effects of carbofuran on the testis of male rats. The activities of beta-glucuronidase (beta-G), glucose-6-phosphate dehydrogenase(G-6-PD) and lactate dehydrogenase isoenzyme-x (LDHx) in serum and testis homogenate were determined for the rats given carbofuran at the dises of 0.3, 1.5 and 3.0 mg/kg orally for 7, 35 and 77 days. The results showed that after 7 days, the activities of beta-G in serum in all exposed groups were lower than those in control (P < 0.05). The activities of beta-G in testis homogenate in 0.3 mg/kg and 3.0 mg/kg were higher or lower than those in control (P < 0.05), respectively. After 77 days, the activities of G-6-PD in serum both in 1.5 mg/kg and 3.0 mg/kg were lower than those in control (P < 0.05). The activities of LDHx in testis homogenate in 3.0 mg/kg were lower than those in control (P < 0.05). It suggested that exposure to carbofuran could testis damage.
