title: [Immune complex in the wall of the gallbladder in patients with cholelithiasis: deposition and its pathological significance].
abstract: The gallbladder specimens from 53 patients with cholelithiasis were studied by immunohistochemical method. Deposition of immune complex (IC) was observed on the mucosal and glandular epithelium in 84% of patients with gallstones and 47% of patients with choledocholithiasis. IgG and C3 were the most frequent complement component demonstrated at the site of IC deposition, but Clq, factor B and C4 were also present in many cases, suggesting the local complement activation. We conclude that IC may play a pathogenetic role in the injury of the mucosa and tissue of gallbladder in patients with cholelithiasis.
