Abstract

Enterosgel effect on morphofunctional indices of the small intestine has been ascertained in experiments on animals, histochemical, electron-microscopic and morphometric methods being used. Enterosorbent in the dose of 0.3 g/kg body weight was injected orally to the guinea-pigs for 14 days. The results of the investigations prove the severe burn traumas to result in sufficient structural changes in the small intestine wall which causes impairment of membranous digestion processes and absorption of nutrients. It is to be noted that the developing burn disease results in the increase of changes severity and reaches the highest values at the stage of septicotoxemia. The enterosorbent assessed positively affects morphofunctional values of the small intestine. The enterosorbent does not enhance conventional development of the pathologic process but considerably decreases its manifestation. The enterosgel promotes the improvement of membranous digestion and absorption in the small intestine, increasing alkaline phosphatase action and rising the number of endocellular vesicles in epitheliocytes having brush margins.

摘要

在动物实验中,采用组织化学、电子显微镜和形态测量方法,已确定肠凝胶对小肠形态功能指标的影响。以0.3 g/kg体重的剂量给豚鼠口服肠吸附剂,持续14天。研究结果证明,严重烧伤创伤会导致小肠壁出现充分的结构变化,从而损害膜消化过程和营养物质的吸收。需要注意的是,正在发展的烧伤疾病会导致变化严重程度增加,并在败血症毒血症阶段达到最高值。所评估的肠吸附剂对小肠的形态功能值有积极影响。肠吸附剂不会促进病理过程的常规发展,但会显著降低其表现。肠凝胶促进小肠膜消化和吸收的改善,增加碱性磷酸酶活性,并增加具有刷状缘的上皮细胞内细胞囊泡的数量。
