In-vitro studies of gallstone dissolution: the effect of added heparin in bile salt solutions. 1977

C M Furnival, and W Burnett, and M K Green, and N C Selvage, and G Cavaye, and I R Hardie

The dissolving effect of four bile salt solutions (sodium cholate, sodium taurocholate, sodium deoxycholate and sodium chenodeoxycholate) upon gallstones was tested in an in-vitro preparation, using 226 stones from 38 patients. The effect of each solution was measured by recording weight loss in the gallstone at the end of a ten-day period of immersion in the bile salt solution. Sodium deoxycholate and sodium chenodeoxycholate produced the greatest average weight loss in the groups of stones tested with pure bile salt solutions, but the addition of heparin to solutions of sodium cholate and sodium deoxycholate produced a significant increase in weight loss in these solutions. This effect of heparin in the presence of bile salts, in comparison with the failure of heparinized saline to induce weight loss in gallstones, is discussed. Sodium chenodeoxycholate cannot be recommended for clinical use on the grounds of its toxicity, and in view of the possible toxicity of sodium deoxycholate it is concluded that a combination of sodium cholate with heparin is the optimum solution for the dissolution of retained intraduct calculi in vivo.

D006493 Heparin A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.

D001647 Bile Acids and Salts Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones. Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
