Light- and electron-microscopical study of a case of gold salt-induced hepatotoxicity.

A 56-yr-old woman with long-standing rheumatoid arthritis exhibited jaundice, pruritus and abdominal discomfort after 8 yr of periodic gold sodium thiomalate injections amounting to a cumulative dose in excess of 2.5 gm. Histopathological examination of the liver biopsy specimen showed submassive loss of parenchyma, collapse of reticulin and mixed cellular inflammatory infiltrates.

Chromium 51-ethylenediaminetetraacetate test: a useful test in the assessment of inflammatory bowel disease.

We evaluated the usefulness of urinary excretion values in assessing mucosal damage in inflammatory bowel disease after administration of chromium 51-labeled EDTA either orally or rectally. In the oral study, 19 controls, 18 patients with Crohn's disease, and 13 patients with ulcerative colitis were given 100 microCi 51Cr-EDTA by mouth. The amount of 51Cr-EDTA in a 24-hour urine collection was expressed as a percentage of the ingested dose.

Antibody-dependent cell-mediated cytotoxicity in serum samples from patients with ulcerative colitis. Relationship to disease activity and response to total colectomy.

A group of six medically treated patients with ulcerative colitis were followed for up to 30 months along with eight additional patients who underwent proctocolectomy. Patients were examined frequently, and serum samples were collected for antibody-dependent cell-mediated cytotoxicity studies. Clinically active disease was substantiated by history, physical examination, laboratory investigations, proctoscopy and, when feasible, by rectal and/or colonic biopsy specimens.
