Serum bile acids in liver disease

Serum bile acids have been measured in patients with a wide variety of liver diseases using a technique which separates the major individual conjugated and free bile acids. Total serum bile acids may be elevated up to 100 times the normal concentration in patients with liver disease and this increase consists largely of conjugated bile acids. The ratio of glycine-conjugated to taurine-conjugated bile salts is low in all types of liver disease and this is found particularly in the serum of patients with obstructive jaundice. There is a decrease in the ratio of trihydroxy:dihydroxy cholanic acid in patients with cirrhosis.

Abnormal lactic dehydrogenase isoenzyme patterns in ulcerative colitis with precancerous change

The isoenzyme pattern of lactic dehydrogenase was measured in rectal biopsies from six patients with ulcerative colitis in whom precancerous histological changes had been independently recognized. There was a highly significant increase in the ratio of isoenzymes IV + V to I + II. This suggests that lactic dehydrogenase isoenzyme measurement may prove a valuable addition to histology in the recognition of precancer in ulcerative colitis.

Determination of individual bile acids in biological fluids by thin-layer chromatography and fluorimetry

A method is described for the separation and determination of individual bile acids in serum and in intestinal contents, employing thin-layer chromatography and fluorimetry. The mean recovery from intestinal juice was 94% and from serum 82%. Normal values for the individual bile acids of serum and examples of clinical applications of the method are given.

Paltiel: a note

A good deal of effort and ingenuity has been devoted to the problem of establishing the historical identity of Palṭiel, an enigmatic figure in the eleventhcentury chronicle of Ahima'as. In this work, the author relates what purports to be the history of his family over the previous two centuries and gives pride of place to one Palṭiel ben Shefaṭyah, an astrologer who rose to high office under the Fṭimid Caliph al-Mu'izz in Tunisia and Egypt. The family, according to Ahima'aṣ, had lived in Oria, in southern Italy, for generations. Then came the Fṭimid raids on the Italian mainland. With al-Mu'izz as their commander, 'they devastated the entire province of Calabria, and reached Oria, on the borders of Apulia; they besieged it, defeated all its forces; so that the city was
