Lymphocyte and macrophage subpopulations in pelvic ileal pouches.

Mucosal characteristics of pelvic ileal pouches.

This study aimed to investigate the degree of colonic metaplasia in ileo - anal pouches. Biopsy specimens from 25 patients with functioning pouches, eight of whom had pouchitis, were studied using routine histology, mucosal morphometry, mucin histochemistry, and immunoperoxidase staining with monoclonal antibodies directed towards a 40kD colonic protein and a small bowel specific disaccharidase...

ALTERATION OF T-LYMPHOCYTE SUBPOPULATIONS IN SUBACUTE AND CHRONIC BRUCELLOSIS

Human brucellosis is a major health problem in developing countries. A number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. Since the pathophysiology of this change is not well understood, we studied the T-cell subsets during the acute, subacute and chronic forms of human brucellosis. In this study we found alterations...

Ki-67 and p53 expression in ileal pouches.

Development of dysplastic lesions that may potentially lead to cancer is sometimes reported within the ileal pouches. Dysplasia is in turn associated with increased expression of proliferation indices. The goal of this study was to evaluate the mitotic activity and possible expression of p53 in the epithelium within the ileal pouches in patients with chronic ulcerative colitis. The study invol...

Lymphocyte subpopulations.

T-lymphocyte subpopulations in uveitis.

Following an inconclusive study of differential lymphocyte counts in uveitis in which the peripheral blood was examined only once in the course of each case a longitudinal study has been carried out in patients with acute anterior uveitis. Venous blood lymphocytes were examined at intervals throughout the course of the illness, from presentation until six months later. No changes in E-rosetting...
