Serum albumin, pseudocholine-sterase, and transaminases in the assessment of liver function before and after venous shunt operations.

This paper records biochemical and follow-up observations on 153 patients with cirrhosis who have had a shunt operation. The experience confirms that no shunt operation should be undertaken on a patient whose serum albumin level is less than 3.2g.%. Low pseudocholinesterase levels are of help diagnostically but the main value of this test is in indicating whether or not liver function will deteriorate after a shunt operation in any given patient.

Observations on the effect of magnesium on blood coagulation.

Previous observations on the effect of oral magnesium and peptone on thrombin generation time are examined. The smallest amounts of magnesium and peptone regularly producing a significant shift demonstrable after one hour are 0.25 g. magnesium and 15 g. peptone. The oral effect can be reproduced by the intravenous injection of magnesium. The minimum amount required is 50 mg. The effect is transient, and after 30 minutes can no longer be demonstrated. Amounts of magnesium of the same order as those acting on intravenous injection can produce a shift of thrombin generation time in vitro. This action of magnesium in vitro can be antagonized by the addition of calcium.
