Hepatitis in children with acquired immune deficiency syndrome. Histopathologic and immunocytologic features.

abstract：BACKGROUND & AIMS:Studies in gastrin-deficient mice have demonstrated critical roles for gastrin peptides in the regulation of gastric acid secretion, but the relative contributions of amidated (G-17) and glycine-extended (G17-Gly) gastrin remain unclear. We examined the effects of these 2 forms of gastrin on acid secr...
