Trace amounts of volatile sulfur compounds were determined in the expired alveolar gas by gas chromatography. Among these sulfur containing substances, methyl mercaptan and dimethyl sulfide were quantitatively analyzed in 116 subjects; 53 normal, 13 acute hepatitis, 11 chronic hepatitis, 20 hepatic cirrhosis, and 19 stomach ulcer and/or biopsy of gastric mucosa. Fasting level of dimethyl sulfide in cirrhotics was 4.05 +/- 1.06 ng/dl, significantly elevated by comparison with normal controls (1.54 +/- 0.09 ng/dl) (P less than 0.05). In contrast, methyl mercaptan did not show a statistically significant rise in this study. The implications of the significant increase in dimethyl sulfide concentration in liver cirrhosis are discussed.

We evaluated whether assay of tissue polypeptide antigen (TPA) in sera is valuable for the determination of cancer stages compared to other tumor markers such as CEA, AFP, beta2-microglobulin, ferritin, and elastase-1. The study population consisted of cancer patients (33 gastric cancers, 7 colo-rectal cancers and 15 hepatomas), 169 patients with benign gastro-enteric diseases and 72 healthy volunteers. The percentage of positive cases for TPA (higher than 200 u/l) was 61% in gastric cancer, 71% in colo-rectal cancer and 87% in hepatoma. In certain non-cancerous conditions, such as gastric ulcer (active stage), acute hepatitis and chronic hepatitis, the TPA levels were increased over the level of healthy volunteers. There was no significant correlation between TPA and the other tumor markers. Our study suggests that TPA may be useful in the identification and evaluation of cancer patients.
