The spermatic cords of 120 adult male rats were injected with long effec-tive procaine. Ten days after the injection, the structure of the seminiferoustubules of testes was markedly changed, and spermatogenesis was severelyimpaired. Most of the primary spermatocytes and the spermatids became defor-med and lost; but the spermatogonia and sertoli cells in the seminiferous tubules,and interstitial cells and small blood vessels in the interstitial tissue showednormal structures. The epididymides showed no significant...

The spermatic cords of 120 adult male rats were injected with long effec-tive procaine. Ten days after the injection, the structure of the seminiferoustubules of testes was markedly changed, and spermatogenesis was severelyimpaired. Most of the primary spermatocytes and the spermatids became defor-med and lost; but the spermatogonia and sertoli cells in the seminiferous tubules,and interstitial cells and small blood vessels in the interstitial tissue showednormal structures. The epididymides showed no significant changes. Ninetydays after the injection, the injured seminiferous tubules can, be returned tonormal. The mentioned above result and the possible mechanism was furtheranalysed and discussed in this paper.

在120只雄性成年大鼠精索内注入长效普鲁卡因,10天以后显示睾丸内曲精小管有明显变化,精子发生受到严重干扰,主要表现为大多数初级精母细胞和精子细胞发生变性、脱落;但曲精小管内的精原细胞和支持细胞保持不变,间质组织中的间质细胞和小血管结构正常。附睾无明显变化。注药90天以后,受损坏的曲精小管可恢复正常。本文对上述实验结果和可能性机理作了进一步分析和讨论。

105 rats were given T2 toxin 0.6-0.9 mg/kg sc.More than 50% animals died within 20 h after intoxication,thereafter death occurred rarely. At necropsy, the major gross changes of 26 rats killed 6 h after sc T2 0.6-2.4 mg/kg were hemorrhages in small intestine and spleen and atrophy of thymus. Histopathological observation revealed a radiomimetic damage of intestinal mucosa, lymphoid organs, hematopoietic tissue and testicular spermatogenic tissue. The featuresof T2-induced lesion were as follows: digestive tract...

105 rats were given T2 toxin 0.6-0.9 mg/kg sc.More than 50% animals died within 20 h after intoxication,thereafter death occurred rarely. At necropsy, the major gross changes of 26 rats killed 6 h after sc T2 0.6-2.4 mg/kg were hemorrhages in small intestine and spleen and atrophy of thymus. Histopathological observation revealed a radiomimetic damage of intestinal mucosa, lymphoid organs, hematopoietic tissue and testicular spermatogenic tissue. The featuresof T2-induced lesion were as follows: digestive tract lesion occurred early and repaired rapidly; bone marrow lesion might associate with proliferation of bone tissue; testes lesion involved not only the seminiferous tubules but also the interstital tissue,hepatic cell injuries might be observed within 24 h after intoxication.

105只大鼠0.6—0.9mg/kgT2毒素sc给毒,半数以上动物在给毒后20h内死亡,此后死亡动物很少。26只大鼠0.6—2.4mg/kg T2sc给毒后6h活杀尸检,肉眼所见的主要病变为小肠和脾出血及胸腺萎缩。病理组织学观察可见肠粘膜、淋巴器官、造血组织和睾丸造精组织的拟放射损伤。T2引起的病变特点是:消化道病变发生早,修复快;骨髓损伤可伴有骨组织增生;睾丸损伤不仅累及曲精小管,而且还累及间质;给毒后24h内可查见肝细胞损伤。

After the spermatic cords of 13 rhesuses were injected with long effectiveprocaine, the testes of the rhesuses changed markedly. The changed degree of semini-ferous tubules of testes and the length of recovery to normal structure varied withdifferent dosages. No remarkable changes were observed in interstitial cells. Thesecreted testosterone did not decreased. There was no toxic reaction. This studyhas significance in clinical application of male contraception and theoreticalresearch of reproduction.

在13只恒河猴精索内注射长效普鲁卡因后睾丸发生明显变化,给药剂量不同,睾丸曲精小管生精细胞改变的程度和恢复正常的时间亦不同。睾丸间质细胞无明显变化,睾酮分泌不减少,无毒性反应。对临床节育应用及生殖理论研究均具有重要价值。
