[Importance of carcinoembryonic antigen, alpha-fetoprotein and cholylglycine in differential diagnosis of viral hepatitis B and mechanical jaundice].

Fifty-four patients with viral hepatitis B (VHB) were examined at the height of the disease as were 30 patients with mechanical jaundice (MJ) of tumorous etiology and 19 normal persons. Mechanical jaundice was mainly characterized by a considerable growth of the concentration of carcinoembryonic antigen, whereas VHB by an increase of the cholylglycine level. Concomitant detection of those markers can be used in differential diagnosis of parenchymatous jaundice and mechanical jaundice of tumorous etiology.

[A clinical evaluation of enzymologic methods for the differential diagnosis of viral hepatitis and subhepatic jaundice].

Enzymological examination of 113 patients with A and B viral hepatitis (VH) and 41 with obstructive jaundice of tumor origin and 32 with chronic cholecystitis during exacerbation showed an increase of activity of blood serum lactate dehydrogenase (LDG), gamma-glutamyltranspeptidase (GGTP), alkaline phosphatase. The GGTP/LDG ratio is of differential-diagnostic value. Ratio values of 0.
