Abstract
This study aimed at investigating the effect of different sources of dietary fibre on gallstone formation in hamsters. The substances studied were pectin, lignin and psyllium hydrocolloid. The two latter compounds protected hamsters against cholesterol gallstone formation. Lignin resulted in a decrease of the deoxycholic acid concentration and in a rise of the cholic/chenodeoxycholic acid ratio. These changes which are similar to those observed with cholestyramine suggest that lignin acts as a bile acid sequestrant. Psyllium hydrocolloid effected a similar shift of the cholic/chenodeoxycholic acid ratio but it also resulted in a rise of the deoxycholic concentration. This latter finding is not compatible with a bile acid sequestering role of this compound. The addition of alcohol to the drinking-water resulted in the formation of stones rich in pigment. Under these conditions the tendency to form such stones was not checked by either of the investigated substances. Das Ziel dieser Unterredung war, den Einfluß verschiedener Volumen von vergrößernden Stoffen der Diät auf die Gallensteinbildung beim Hamster zu studieren. Dabei wurden die Substanzen Pectin, Lignin und Psylliumhydrokolloid benützt. Die zwei letzteren schützten die Hamster gegen die Bildung von Cholesteringallensteinen. Lignin bewirkte eine Verminderung der Konzentration von Deoxycholsäure und eine Steigerung in der Chol-/Chenodeoxycholsäure-Konzentration. Ähnliche Veränderungen findet man bei Zufuhr von Cholestyramine, was für eine Bindung von Gallensäure bei Lignin sprechen könnte. Psylliumhydrokolloid bewirkte eine ähnliche Steigerung der Chol-/Chenodeoxycholsäure-Konzentration, aber auch eine Steigerung der Deoxycholsäurekonzentration. Der letztere Befund von Psylliumhydrokolloid ist nicht mit einer Bindung von Gallensäure zu vereinbaren. Bei Zugabe von Alkohol zum Trinkwasser wurden pigmentreiche Steine gebildet. Unter diesen Bedingungen wurde die Bildung von solchen Steinen bei keiner dieser angewandten Substanzen vermieden.This publication has 13 references indexed in Scilit:
