Hepatic zinc content in patients with various stages of alcoholic liver disease and in patients with chronic active and chronic persistent hepatitis.

The hepatic zinc content was determined in liver biopsies of patients with alcoholic and nonalcoholic liver disease using proton-induced X-ray emission. The values obtained in postmortem specimens of the liver from 27 patients with no evidence of acute or chronic liver disease served as controls. The mean value and the range of the zinc content in the controls (75 +/- 24 ppm wet weight) are in good agreement with those reported in the literature. The hepatic zinc content in the control group showed no significant age or sex dependence. The mean zinc content was significantly decreased in all groups of patients with alcoholic liver disease. The decrease was comparable in biopsies from patients with alcoholic fatty liver (-56.7%, n = 12), mild alcoholic hepatitis (-50.5%, n = 6) and alcoholic cirrhosis (-45.6%, n = 10). The hepatic zinc content was also distinctly reduced in patients with chronic active hepatitis (-60.3%, n = 15) and in those with chronic persistent hepatitis (-44.9%, n = 8). The estimation of the zinc content in subcellular fractions of the liver performed in postmortem specimens from seven patients with alcoholic liver cirrhosis and in six controls revealed a significant reduction in the zinc content in the fraction containing cell nuclei and membranes and in the mitochondrial fraction. A similar decrease was seen in the 100,000 g supernatant; however, the difference did not attain statistical difference. The zinc content of the microsomal fraction in the controls was lower than in the other three cell fractions.(ABSTRACT TRUNCATED AT 250 WORDS)

Endotoxaemia in patients with liver cirrhosis and upper gastrointestinal bleeding: detection by the chromogenic assay with plasma Tween 80 pretreatment.

A recently developed chromogenic endotoxin assay with plasma Tween 80 pretreatment was compared with the conventional dilution and heating method. Plasma endotoxin was measured in patients with liver cirrhosis and upper gastrointestinal (GI) bleeding by these methods. Plasma endotoxin concentration was calculated from an individual internal standard curve by adding three different standard endotoxin solutions to each sample. By the conventional heating method, added standard endotoxin gave different OD values in each sample and the slope of the standard curve showed interindividual variations. When sample plasma from chronic alcoholics was pretreated with 1% Tween 80 and ultrasonification after heating, the slope of standard curves was somewhat increased and interindividual variation was minimized. Significantly higher plasma endotoxin levels in cirrhotics with upper GI bleeding compared with those without upper GI bleeding was detected by this Tween 80 method. There was a strongly positive correlation between the endotoxin levels determined by this method and those determined by the perchloric acid method and endotoxin-specific substrate in patients with upper GI bleeding. Endotoxin levels, which were elevated 1-2 days after the bleeding, tended to decrease as patients recovered. In summary, the recovery of endogenous and exogenous endotoxin from plasma sample was increased by adding Tween 80 before the chromogenic substrate assay. Transient elevation of plasma endotoxin was demonstrated by this Tween 80 method in patients with liver cirrhosis and upper GI bleeding.
