Prevention of gallstone formation in rabbits by the oral administration of kanamycin.
Rabbits fed a diet containing 40 per cent casein, 15 per cent oleic acid and 45 per cent laboratory pellets developed glycoallodeoxycholic acid and glycodeoxycholic acid gallstones. The oral administration of kanamycin prevented allo bile acid stone formation in the oleic acid fed rabbit without leading to cholesterol gallstone formation. Kanamycin reduced the concentration of allodeoxycholic acid in the bile of oleic acid fed rabbits from 16.6+/-4.1 per cent of total bile acids to 1.1+/-1.1 per cent, with a reciprocal increase in deoxycholic acid concentration. The allodeoxycholate concentration was far below that found in control bile samples, 10.2+/-2.3 per cent. If the effect of kanamycin on the bile composition is by its antibiotic action, this eliminates the importance of a hepatic contribution to allodeoxycholate stone formation.
