The amino-terminal peptides of type III procollagen (PIIIP) in the urine of 40 patients with various liver diseases were determined with a commercial radioimmunoassay kit. The level of urinary PIIIP (uPIIIP) was correlated well with serum PIIIP (sPIIIP) in 9 patients, the coefficient of correlation being r = 0.836 (p less than 0.01) and the regression line being y = 1.42x + 24. Urinary PIIIP consisted of at least 4 different molecular species with molecular weights of 49 k, 18 k, 10 k and 4.6 k as estimated by column chromatography on Sephadex G-100. Furthermore. uPIIIP was found to be significantly elevated in acute hepatitis, chronic hepatitis, liver cirrhosis, hepatocellular carcinoma and other liver diseases, in which the elevation of sPIIIP has been reported by others. The mean values +/- standard deviations of uPIIIP were 44.0 +/- 32.0, 60.4 +/- 32.0, 62.0 +/- 46.5, 53.0 +/- 27.1 and 48.1 +/- 22.8 ng/ml for the respective liver diseases, and 13.2 +/- 4.5 for the non-hepatic disease group
