Rectal reaction to injected ulcerative colitis leucocytes and plasma.

PATIENTS Seventeen ambulatory adult males with wellestablished diagnoses of chronic ulcerative colitis were studied. Rectal biopsies were compatible in each case. Patients were chosen who were in clinical remission, and without friable or ulcerating mucosa at the time of the investigation. Fifteen patients had been taking salicylazosulphapyridine (Azulfidine) for six to 24 months. None had been taking adrenal steroids during the preceding three months (Table I). Four patients with Laennec's cirrhosis and three with duodenal ulcer were also tested.
