Abstract
Analysis of the bilirubin lime stone and cholesterol-bilirubin lime stone of the Japanese was performed and the following results were obtained.
1. As a component of the gall stone, palmitic acid was found in relatively greater quantity in the bilirubin lime stone than in the cholesterol-bilirubin lime stone. The former stone contains palmitic acid ester of cholesterol.
2. Desoxycholic and chenodesoxycholic acids were found as components of each type stone but no cholic acid was found. The bilirubin lime stone contains chenodesoxycholic acid 3.5 times as much as desoxycholic acid.
