摘要:

【摘要】 目的 测定室内条件下棉酚对布氏田鼠的不育效果。方法 采用一次性定量灌胃法测定该药对试鼠精子品质及睾丸、附睾组织的作用。结果 棉酚可对精子细胞和精母细胞造成损害,并损伤睾丸组织。剂量在20~100 mg/kg时,睾丸和附睾脏器系数明显下降;高于20 mg/kg的剂量导致精子密度下降、精子畸形率明显增加;剂量高于60 mg/kg对布氏田鼠有致死作用。结论 20~100 mg/kg剂量的棉酚对雄性布氏田鼠有明显的抗生育效果,且高剂量的棉酚对布氏田鼠有致死作用。

Abstract:

【Abstract】 Objective To study the anti?fertility effect of gossypol to Lasiopodomys brandtii. Methods The effect of gossypol to sperm quality, testis and epididymis tissues of L.brandtii was tested with one?off quantitative gastric gavages. Results Gossypol did harm to spermatids, spermatocytes and testis tissue lesions. Testis and epididymis tissues coefficient decreased obviously at the dosage of 20-100 mg/kg, and sperm concentration reduced and sperm malformation increased at 20 mg/kg. It leaded to the death of L.brandtii when the dosage exceeded 60 mg/kg. Conclusion The gossypol had significant anti?fertility effect on male L.brandtii at the concentration of 20-100 mg/kg, but it was lethal at high concentrtion.
