ACTH-producing pheochromocytoma.

A benign adrenal medullary tumor that secreted adrenocorticotropic hormone (ACTH) was associated with bilateral adrenocortical hyperplasia and clinically evident Cushing syndrome. The clinical and chemical features were those usually associated with pituitary Cushing disease, including partial suppression of urinary OH steroids after administration of 8 mg of dexamethasone. The fractionization of the tumor's ACTH revealed 70% little "biologically active" ACTH, which is usually found in this concentration only in pituitary tissue.

T rosettes in alcoholic cirrhosis of the liver.

Thirty patients with alcoholic cirrhosis of the liver were studied for in vivo and in vitro correlates of cellular immunity. Seventy-seven percent failed to be sensitized to dinitrochlorobenzene, indicating impairment of the in vivo cellular immune response. A significant decrease in the number of T-rosette-forming cells was observed in this group of patients (.01 smaller than P smaller than .025). This finding suggests that the active T-rosette test is a valuable tool in detecting partial alterations in cell-mediated immunity in alcoholic cirrhosis of the liver. Our results also suggest that rosette formation is a more sensitive indicator of cell-mediated immunity than phytohemagglutinin-stimulated blastogenesis in patients with alcoholic cirrhosis of the liver.
