A possible mechanism of the protective effect of Triton WR1339 during chronic CC14-hepatitis was considered. Supposing that the improvement of the process was due to the intensification of the lysosome heterophage function the authors studied the intensity of the C14-albumin uptake by the liver and its subcellular distribution in the liver of rats in the administration of the detergent to the animals with chronic CCI4-hepatitis, Preliminary administration of the detergent failed to influence the intensity of C14-albumin uptake; subsequent administration of triton WR1339 to rats with toxic hepatitis decrease the protein uptake which reached the values in intact rats. In chronic hepatitis C14-albumin was concentrated in the lysosome fraction. Administration of trition WR1339 to CCI4-treated animals was not accompanied by any coincidence in the peaks of labeled protein and lysosome enzymes. The selective participation of lysosomes of the Kupffer cells providing a more rapid restoration of the liver in chronic hepatitis is discussed.
研究了吐温WR1339在慢性四氯化碳性肝炎期间保护作用的可能机制。假设病情改善是由于溶酶体异噬功能增强,作者研究了慢性四氯化碳性肝炎大鼠在给予去污剂时肝脏对C14-白蛋白的摄取强度及其在肝脏亚细胞中的分布。预先给予去污剂未能影响C14-白蛋白的摄取强度;随后给中毒性肝炎大鼠给予吐温WR1339可降低蛋白质摄取,使其达到正常大鼠的水平。在慢性肝炎中,C14-白蛋白集中在溶酶体部分。给四氯化碳处理的动物给予吐温WR1339后,标记蛋白峰和溶酶体酶峰未出现任何重合。讨论了枯否细胞溶酶体的选择性参与在慢性肝炎中使肝脏更快恢复的作用。
