Two-micrometer sections of methacrylate-embedded kidney were used to investigate the enzymatic activities of mouse kidney where the proximal tubule and Bowman's capsule from the same corpuscle were viewed in the same section. Alkaline phosphatase, acid phosphatase, 5'-nucleotidase, gamma-glutamyl transpeptidase, N-acetyl-beta-glucosaminidase, leucine aminopeptidase, alpha-naphthyl butyrate esterase, and adenosine triphosphatase activities were observed in the proximal tubule, but only 5'-nucleotidase, alpha-naphthyl butyrate esterase, and alkaline phosphatase were observed in the squamous portion of the parietal epithelium of Bowman's capsule. The use of methacrylate-embedded tissue allowed more precise localization of enzymatic activity than is possible with most frozen sections. This may provide interesting applications not only for characterization of kidney diseases but also for characterization of other normal and abnormal tissues.

Cholestasis is a multifactorial disorder with various biological, infectious, toxic, genetic and metabolic manifestations, its principal feature presented as reduced bile flow or abnormalities in bile formation. It has lately been accepted that some specific biological markers would shorten the period needed to establish a positive diagnosis, as currently it is necessary to navigate through a complex diagnostic protocol for this disorder. The purpose of this study was to establish some biological parameters and biomarkers useful for cholestasis management in children. Two hundred thirty-two children with cholestasis were selected, during a six-year study. The biological indicators followed were serum bilirubin, gamma-glutamyl transpeptidase, aspartate transaminase, alkaline phosphatase, lactate dehydrogenase, serum cholesterol and triglycerides. Our data showed that certain biological parameters are more often involved in the various forms of cholestasis, and the conclusions of this study could be useful in the early detection of cholestasis and appropriate disease management.

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.
