title: Factors affecting C3 in intestinal schistosomiasis.
abstract: Complement component C3 was investigated in sera of a group of schistosomal patients free from obvious nephritis. C3 was studied in relation to S. mansoni egg count, presence of HBsAg, and liver functions. C3 level was low in schistosomal patients than normal individuals. Levels were low in both HBsAg --ve and HBsAG +ve schistosomal patients. No significant difference was found between HBsAg --ve and HBsAg +ve in one hand, and between patients with egg counts more than 400 and those with egg counts less than 400 eggs/1 gr as regards level of C3 on the other hand. Presence of ascites did not affect C3 concentration. Positive correlation was found with Serum albumin, but not with prothrombin concentration serum alkaline phosphatase or serum transaminases.
