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...

Differential diagnosis of acute viral hepatitis, persistent chronic hepatitis, aggressive chronic hepatitis, and post-necrotic cirrhosis can reasonably be achieved on the basis of three well-known liver-function tests: aspartate aminotransferase, alanine aminotransferase, and glutamate dehydrogenase. With use of principal-component analysis, these four liver diseases can be characterized by two...

OBJECTIVE To determine the effect of low dose interferon alfa (human lymphoblastoid interferon) on aminotransferase activities in chronic non-A non-B hepatitis. DESIGN Prospective randomised controlled parallel group study of active treatment versus no treatment carried out over 16 weeks and preceded by baseline measurements at weeks 8 and 4 and time zero. SETTING HEPATOLOGY outpatient clin...

Rat liver tyrosine aminotransferase (L-tyrosine:2oxoglutarate aminotransferase; EC 2.6.1.5.) has been studied thoroughly with respect to its inducibility by various hormones. Recently, it has been shown that this enzyme can be stimulated by cyclic AMP 1 and by theophylline 2, which is capable of elevating intracellular levels of cyclic purine nucleotides. Moreover, this enzyme was shown to be i...
