A 60-days feeding trial was conducted to study the effect of higher temperature (32°C) in comparison to ambient temperature (24.5°C) on different metabolic enzyme namely, aspartate aminotransferase (AST), alanine aminotransferase (ALT), adenosine triphosphatase (ATPase), acid phosphatase (ACP) & alkaline phosphatase (ALP) activities in different tissues of Pangasianodon hypophthalmus. AST activ...

SUMMARY Three pa ticnts admitted because of slightly increased serum amino trans fcrases were found to have Addison's disease. A review of 16 other patients with addison 's disease who had serum aminotransferase activity (aspartate aminotrans­ferase (ASAT) and alanine aminotransferase (ALAT) J determined prior to treatment revealed one more patient with slightly increased aminotransferase acti...

In order to examine the effect of exogenous melatonin on selected blood indices, dairy goats were given pineal gland hormone at a dose of 0.1 mg/kg body weight. Next, one and four hours after the melatonin had been administered, blood samples were collected from the goats in the control and treated groups in order to determine the levels of glucose, total cholesterol, triacyloglycerides, free f...

  The aims of the present study were to determine the best time for egg stripping after ovulation and to study oocyte over-ripening in the Caspian brown trout (Salmo trutta caspius). Eggs were retained in the female abdominal cavity for 40 days post ovulation (DPO). Partial volumes of eggs stripped from 10 individually identified females at 10 days intervals and fertilized with a pool of semen ...

Wolf et al. (1) found little or no serum aspartate aminotransferase (EC 2.6.1.1) activity in the sera of 11 of 19 patients undergoing long-term hemodialysis. The authors concluded that low aminotransferase (transaminase) activities seen in these patients may have been due to loss of the enzyme and (or) to pynidoxine depletion during long-term dialysis. We recently examined the sera of 54 long-t...

AIM To provide a simple surrogate marker predictive of liver cirrhosis (LC). METHODS Specimens from 302 patients who underwent resection for hepatocellular carcinoma between January 2006 and December 2012 were retrospectively analyzed. Based on pathologic findings, patients were divided into groups based on whether or not they had LC. Parameters associated with hepatic functional reserve were...

We measured the activities of two mitochondrial enzymes, the mitochondrial form of aspartate aminotransferase (EC 2.6.1.1) and glutamate dehydrogenase (EC 1.4.1.2), in the serum of apparently healthy persons (n = 84) and patients suffering from chronic liver diseases (n = 43). The distribution of activities for glutamate dehydrogenase, but not mitochondrial aspartate aminotransferase, was sex-d...

Following major tissue injury, hyaluronic acid production increases as a rapid response survival mechanism. Increased hyaluronic acid production and turnover are often associated with increased hyaluronidase activity, the enzyme that degrades hyaluronic acid. We investigated whether hyaluronic acid and hyaluronidase can be used as non-invasive markers of acute disease activity in hepatitis C by...

We investigated the enzyme activity of the blank in the spectrophotometric determination of the aminotransferase activities and aspartate aminotransferase activity. 6 lactate dehydrogenase and 3 malate dehydrogenase preparations from different manufactures and from different organs showed additional and contaminating activity. The additional activity depends upon the 2-oxoglutarate concentratio...
