Objective: The present study aimed to assess of four liver enzymes, Alanine Aminotransferase (ALT), Aspartate Transaminase (AST), Alkaline Phosphatase (ALP) and Gamma-Glutamyl Transpeptidase (GGT). Material and Methods: Based on periodontal clinical parameters, sixty four patients with chronic periodontitis (CP) and twenty four controls were enrolled in the study. Saliva and serum samples were collected and Automated Chemistry Analyzer AU 480 was employed to assess levels of enzymes. Results: Compared to healthy controls, the levels of the four enzymes were significant increased in serum of patients, especially in the severe group while in the saliva a significant increase observed only in the level of AST. Moreover, Alanine Aminotransferase (ALT), Aspartate Transaminase (AST), Alkaline Phosphatase (ALP) and Gamma-Glutamyl Transpeptidase (GGT) the levels of these enzymes in serum were significantly higher than those in saliva. Conclusion: ALT, AST, ALP and GGT serum levels are suggested to be important indicators for disease progression as well as predict the liver health.

Abstract Serum γ-glutamyl transpeptidase (GGT), leucine aminopeptidase, alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase activities were assayed in controls and in patients with liver, pancreatic, or bone disease. GGT activity was above normal in all forms of liver disease studied (viral hepatitis, cirrhosis, cholecystitis, metastatic carcinoma to liver, pancreatic carcinoma, liver granuloma, and acute pancreatitis). GGT more sensitively indicated hepatic disease than did alkaline phosphatase, much more so than did leucine aminopeptidase. GGT was disproportionately more active in relation to the transaminases in cases of intraor extrahepatic biliary obstruction; the reverse was true in cases of viral hepatitis. GGT activity was normal in children, adolescents, and pregnant women, and in cases of bone disease and renal failure. Kinetic measurement of GGT activity offers a simple, sensitive, and direct means for distinguishing whether bone or liver is the source of increased serum alkaline phosphatase activity. Activity was highest in obstructive liver disease.

Results of many studies, summarized in this review, support the hypothesis that carcinogen-induced hepatocellular carcinomas develop from phenotypically-altered hyperplastic hepatocellular nodules; these in turn apparently arise from smaller focal collections of hyperplastic cells referred to as hepatocellular islands. The very recent recognition that phenobarbital, when administered after carcinogens, fosters the outgrowth of hepatocellular islands and carcinomas, now provides the means for studying stages of initiation and promotion in hep-atocarcinogenesis. In addition, the recognition that enzymatic alterations, particularly the acquisition of canalicular gamma glutamyl transpeptidase activity, loss of ATP'ase activity, and loss of glucose-6-phosphatase activity that characterize many islands, have been particularly useful for measuring and evaluating the growth kinetics and heterogeneity of the islands. Evidence is presented that periportal gamma glutamyl transpeptidase positive hepatocytes are considerably more abundant after four weeks of feeding .02% 2-acetyl-aminofluorene to young rats than in control animals, and that the outgrowth of these cells is fostered by a distinctive type of periportal reparative hyperplasia. The cells appear to arise from a pool of cells that are normally abundant in periportal location in young growing rats. The studies suggest that it may now be possible to develop short term in vivo bioassays for initiators, promoters, and complete carcinogens in the rodent liver.
