In order to assess the diagnostic aid of serum gammaglutamyl transpeptidase values in hepatitis, obstructive jaundice and pancreatitis, four groups of 14 health dogs were subjected to the gastric intubatin of CCl₄(1.5㎖/㎏ of body weight), the ligation of common bile duct, the ligation of pancreatic ducts and the injection of chloroform(0.2㎖/㎏ of body weight) in the parenchyma of the pancreas.
Some serum enzymes serum glutamic pyruvic transaminase(SGPT), serum glutamic oxalacetic transaminase(SGOT), total bilirubin, amylase and lipase known to be indicative of hepatic and pancreatic diseases were monitored. In comparision of these enzymes, gamma-glutamyl transpeptidase(GGTP) valuers were determined in these dogs before and after the experimental procedures. The results were summarized as follows :
1. In CCl₄ intoxication gorup, there were no significant changes in serum GGTP activities(mean: 6.0∼14.6 IU/L).
2. In bile duct ligation group, serum GGTP activities shelved marked increases, beginning at postsurgical day 1 and rose the highest mean value(342.7 IU/L) on day 12. Then the activities never approached to the base-line values.
3. After the ligation of pancreatic ducts and the injection of chloroform in the pancreas, serum GGTP activities did not rise throughout the experiment.
4. SGPT : GGTP ratio did not increase in bile duct ligation group, but increase markedly in ccl₄intoxication group.
5. The results indicated that serum GGTP values or SGPT : GGTP ratio could provide valuable indicators for differential diagnosis between hepatobiliary obstruction and hepatocellular disease.
