In this paper studies on the chronic toxicity and curative effect of Tilorone were Carried out. Tilorone was given to experimental silicotic dogs in two dosages (20mg/kg, 10mg/kg) a week for six months. Resalts showed that the silicotic lesions in treated dogs were much railder than those of the Controls. The differences of collagen contents of whole lung and hilar lymph nodes between treatment and control groups were significant.Silicotic lesions in treatment groups consist of large foam-like cells aggragated...

In this paper studies on the chronic toxicity and curative effect of Tilorone were Carried out. Tilorone was given to experimental silicotic dogs in two dosages (20mg/kg, 10mg/kg) a week for six months. Resalts showed that the silicotic lesions in treated dogs were much railder than those of the Controls. The differences of collagen contents of whole lung and hilar lymph nodes between treatment and control groups were significant.Silicotic lesions in treatment groups consist of large foam-like cells aggragated in the nodules. Cell necrosis in the lesions were rarely observed. Results obtained indicated that Tilorone possesses a good curative effect on the experimental silicosis in dogs.No alterations in hematologic examination and function of liver and kidney were foud in each treatment groups. Close relationship between the chronic toxic effects and drug accumulation was shown. The main organs damaged were liver and kidney. After administration, the contents of Tilorone accumlated in animal bodies and lesions caused by Tilorone were reduced.

本文旨在探讨梯络龙对狗实验性矽肺疗效及慢性毒性作用。实验分为大(20mg/kg)、小(10mg/kg)剂量组及矽肺对照组,疗程6个月。实验结果表明:治疗组的全肺及肺门淋巴结的胶原蛋白含量均明显低于矽肺对照组。矽结节病变主要由泡沫样细胞及纤维细胞组成,坏死细胞较少,梯络龙对实验性矽肺具有明显抑制病变进展的作用。梯络龙对血象及肝、肾功能未见异常影响。其慢性毒性作用与其在体内的蓄积作用有密切关系。主要受损的器官是肝及肾。于停药后,梯络龙在体内的存留量与其引起的病变有不同程度的下降和减轻。
