摘要:

目的:观察邻苯二甲酸二丁酯(DBP)对雄性小鼠生殖系统的脂质过氧化作用和对抗氧化酶活性的影响,探讨其对雄性小鼠生殖系统的可能作用机制。方法:40只健康雄性ICR小鼠随机分为对照组和200、400和800 mg·kg-1DBP组,每组10只。各剂量DBP组小鼠连续灌胃给予DBP,灌胃剂量分别为200、400和800 mg·kg-1·d-1,对照组小鼠仅给予玉米油溶剂。于染毒满2和4周时各组分别处死5只小鼠,收集睾丸,并测定睾丸组织中丙二醛(MDA)水平及谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)活性。结果:染毒2周后,400和800 mg·kg-1 DBP组小鼠MDA水平明显高于对照组和200 mg·kg-1 DBP组(P<0.05);400和800 mg·kg-1 DBP组小鼠睾丸组织中SOD活性低于200 mg·kg-1 DBP组(P<0.05);各剂量DBP组小鼠睾丸组织中GSH-Px活性均明显低于对照组(P<0.05)。染毒4周后,400和800 mg·kg-1 DBP组小鼠睾丸脏器系数低于对照组和200 mg·kg-1DBP组(P<0.05);400和800 mg·kg-1 DBP组小鼠睾丸组织中MDA水平均高于对照组(P<0.05),200 mg·kg-1 DBP组小鼠睾丸组织中MDA水平低于对照组(P<0.05);800 mg·kg-1 DBP组小鼠睾丸组织中SOD活性明显低于对照组和200、400 mg·kg-1 DBP组(P<0.05);各剂量DBP组小鼠睾丸组织中GSH-Px活性均明显高于对照组(P<0.05)。结论:DBP可诱导小鼠睾丸产生脂质过氧化反应,诱导氧化应激,导致睾丸抗氧化能力下降,造成生殖功能障碍。

Abstract:

Objective To observe the lipid peroxidation of dibutylphthalate(DBP) on the reproductive system of the male mice and its influence in the antioxidant enzyme activities, and to investigate the possible mechanism of DBP to the reproductive system of the male mice. Methods 40 healthy male ICR mice were randomly divided into control group, 200 mg·kg-1 DBP group, 400 mg·kg-1 DBP group, and 800 mg·kg-1 DBP group(n=10).The mice in DBP groups were administrated with 200, 400 and 800 mg·kg-1·d-1 DBP by gavage.The mice in control group were only received corn solvent.5 mice in each group were sacrificed respectively 2 and 4 weeks later, and their testis were collected.The malondialdehyde (MDA) levels, activities of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) in testis tissue of the mice in various groups were detected. Results Two weeks after exposure, the MDA levels in testis tissue of the mice in 400 and 800 mg·kg-1 DBP groups were significantly higher than those in control group and 200 mg·kg-1 DBP group(P<0.05);the SOD activities in 400 and 800 mg·kg-1 DBP groups were lower than that in 200 mg·kg-1 DBP group (P<0.05).Four weeks after exposure, the testis organ coefficients in 400 and 800 mg·kg-1 DBP groups were lower than those in control group and 200 mg·kg-1DBP group (P<0.05);the MDA levels in 400 and 800 mg·kg-1 DBP groups were higher than that in control group (P<0.05), and the MDA level in 200 mg·kg-1 DBP group was lower than that in control group (P<0.05).The SOD activity in testis tissue of the mice in 800 mg·kg-1DBP group was significantly lower than those in control group, 200 mg·kg-1 DBP group and 400 mg·kg-1 DBP group (P<0.05);the GSH-Px activities in testis tissue of the mice in DBP groups were significantly higher than that in control group (P<0.05). Conclusion DBP can induce the lipid peroxidation of the mouse testis and induce oxidative stress, and lead to the descending of testicular antioxidant capacity, then Results in reproductive dysfunction.
