In order to investigate whether the urinary excretion of 1-methylhistidine (1MH) might serve as an objective indicator of meat ingestion and exogenous 3-methylhistidine (3MH) intake, healthy subjects were fed an ovolactovegetarian diet. At five-day intervals they were given meat of

This investigation was undertaken to determine the splanchnic exchange of 3-methylhistidine (3MH) in infection. Hepatic vein, femoral vein, and radial artery catheterizations were performed in 12 febrile patients with infections of varying severity. Differences in arteriovenous 3MH, analyzed by high-performance

A reversed-phase high-performance liquid chromatographic method is described for the determination of 3-methylhistidine content in human urine using pre-column derivatization with phenylisothiocyanate, isocratic elution with 15 mM sodium acetate-acetonitrile (92:8, v/v) and electrochemical detection. The limit of quantitation was 0.1

Metabolism: clinical and experimental, 38(1), 23-29 (1989-01-01)
The present investigation was undertaken in order to determine the release of 3-methylhistidine (3MH) from the splanchnic region and from the leg, and the contributions these make to the increase in urinary 3MH excretion in infection. Thirteen febrile patients with
