In this study, the author intended to examine the validity of the inhaled hydrogen gas clearance method (i-H2) for determination of the hepatic blood flow (HBF), and also to show some applicabilities of the method in experimental animals and patients with liver diseases. Simultaneous determinations of HBF by i-H2 and electromagnetic flowmetry in rabbits revealed an excellent correlation between the values obtained by the two methods. Moreover, HBF in rabbits measured by i-H2 varied in parallel with that by thermocouple flowmetry or laser Doppler velocimetry after administration of norepinephrine, propranolol or glucagon. In carbon tetrachloride-treated rats, HBF measured by i-H2 correlated better with the severity of damage in the sinusoidal structure than the severity of hepatic cell injury or the serum levels of transaminases. HBF as determined by i-H2 was significantly decreased in acute hepatitis (AH), chronic inactive hepatitis (CIH), chronic active hepatitis (CAH), liver cirrhosis (LC) and fatty liver. Reduced HBF in AH returned to normal during recovery of the disease. The ratio of HBF in tumor/normal tissue was greater than 1.0 for hepatocellular carcinoma in contrast to the ratio of less than 1.0 for metastatic liver carcinoma. Propranolol caused a decrease in HBF by 31%, and vasopressin by 39% in patients with CIH or LC. In contrast, glucagon induced its increase by 65%, 35% and 17%, respectively, in patients with CIH, AH and LC.

The influence of 1000 ml of 0.9% NaCl infusion induced hypervolemia on the water-electrolyte and hormonal balance was investigated in HBV-infected patients with chronic persistent hepatitis, chronic active hepatitis and compensated cirrhosis. All examined patients showed higher concentrations of vasopressin and atrial natriuretic peptide and the increased activity of RAA system before the trial. The induced hypervolemia caused the decrease of RAA system's activity and vasopressin concentration and increase of atrial natriuretic peptide's secretion, different in every group of patients. The latent deficiency of calcium and magnesium was found, too. The results showed that all determined patients had water-electrolyte and hormonal disorders, significantly increased in patients with chronic active hepatitis.
