Abstract

This study was designed to evaluate the effects of altered reticuloendothelial function on the formation of nospecific reactive hepatitis in rats. Increased activity of reticuloendothelial system was evoked by methylcellulose treatment (20 mg/100 g). Partial depression of reticuloendothelial system was induced by splenectomy. Experimental nospecific reactive hepatitis was made by Escherichia coli treatment, artificial stomach perforation ileum ligation, respectively. The nonspecific reactive hepatitis thus made evaluated by liver function tests such as AST ALT and alkaline phosphatase. Histological and electron microscopical observation were also done. The results obtained were as follows: 1. Functional and histological changes of nospecific reactive hepatitis deffered with the disign employed. 2. Partial reduction of reticuloendothelial activity by splenectomy didn't influence the serverity of nonspecific reactive hepatitis. 3. Increase of reticuloendothelial activity by methylcellulose treatmetns reduced the severity of nonspecific reactive hepatitis lesion developed by E. coli treatment and stomach perforation, both functionally and morphologically. 4. Changes of nonspecific reactive hepatitis by lieum ligations, however, were aggrevated by increased recticuloendothelial activity. These results showed the divers effect of altered reticuloendothelial function on the degree of nonspecific reactive hepatitis according to the employed experimental designs.
