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
