Biliary excretion of bromosulfthalein in rabbit.

The effect of bromosulfthalein (BSP) infusions at different doses on bile secretion was investigated in anaesthetized rabbits. The patterns of biliary excretion were found to be similar to other mammals, maximal biliary excretion being achieved by an infusion of 0.50 mg X kg-1 body weight X min-1. Bromosulfthalein administered at low doses under the maximum hepatic transport capacity resulted in a clear increase of bile flow which was mainly due to an osmotic mechanism. Supramaximal doses produced no effect on bile flow.

Influence of bile salts on the endogenous excretion of bile pigments.

Effect of the infusion of glycodeoxycholate (GDC), taurocholate (TC) and dehydrocholate (DHC) on bile flow and on bile salt, biliary lipid and bile pigment secretion, has been studied in pentobarbital-anesthetized rabbits. GDC increased bile flow the most, while DHC increased it more than TC. The different choleretic actions of these bile salts cannot be explained by means of variations in their capacity to form micelles. Only GDC and TC were able to stimulate biliary lipid secretion, which suggests that both bile salts increase the formation of mixed micelles. GDC and TC to a lesser extent increased bile pigment excretion, DHC being without effect. These results favour the hypothesis that micellar binding could be an important factor responsible for the effect of bile acids on bile pigment excretion and should not be completely ruled out.

[Histopathological aspects of chromium ulcers].

The authors describe two cases of "cromeholes". Both patients were working in electroplating. The pathology of these lesions demonstrate that it refers to caustic ulcers with necrosis of the epidermis and superficial dermis, with tendency to hyperplasia of neighbouring epidermis and important infiltration of the vessels and specially of the sweat glands.

Duodenal gallstone ileus producing Boerhaave's syndrome.

A case of duodenal obstruction by biliary calculus associated with esophageal rupture is described. CT demonstrated air in the gallbladder, an impacted gallstone in the duodenum, pneumomediastinum, and hydropneumothorax. The present report describes the CT findings of these two rare conditions in the same patient.
