The effect of short-term intragastric arterial infusion of pentagastrin and methacholine on histamine and N tau-methyl histamine secretory rates was evaluated in mongrel dogs in vivo. Doses of pentagastrin and methacholine were chosen that stimulate gastric acid secretion equivalently. Histamine

We have previously demonstrated that both pentagastrin and methacholine can stimulate histamine release from the canine stomach during short term administration of the secretagogues into the gastrosplenic artery. In this study we tested the hypothesis that gastric histamine release determines

A method for the determination of histamine N-methyltransferase (HMT) activity by high-performance liquid chromatography based on post-column derivatization with omicron-phthalaldehyde is described. The determination involves the separation of the substrate, histamine, from its product. N tau-methylhistamine, using a weak cation
Rapid and highly sensitive high-performance liquid chromatographic method for the determination of histamine and 3-methylhistamine in biological samples using fluorescamine as the derivatizing agent.

In order to trace the loss of N tau-methylhistamine, a principal metabolite of histamine, during extraction and purification from human plasma and urine samples, N tau-[3H]methylhistamine was prepared in two steps from N alpha t-butoxycarbonylhistamine (II). In the first step
