transaminase

 [trans-am´ĭ-nās]
any of a group of enzymes that catalyze the reversible transfer of an amino group from a donor, usually an amino acid, to an acceptor, usually a 2-keto acid. Most use pyridoxal phosphate as a coenzyme.

From interpretation of data obtained in this study, evaluation of plasma levels of hepatic enzymes such as Lactate and Glucose-6-phosphate-dehydrogenases, Acid and Alkaline Phosphatases, Alanine and Aspartate Transaminases in Nigerians affected with hematological malignancies could assist in studying the prognostication of hematological malignancies.
Leukopenia is found in 60%-70% of patients, thrombocytopenia in 60%, and mild to moderate elevation of serum transaminase levels in 80%-90% (4,5).
Table: Changes in mean serum bilirubin and alanine transaminase (ALT) from day 0 to day 19 in different animal groups.
Based on the collective evidence available from various sources, it is clear that only very rarely elevations in transaminase levels seen in low to moderate dosages of statins progress to liver failure.
Since, several HCV reports have described normal transaminase levels in about 25%-30% of chronic HCV patients, there may be a potential advantage in assessing serum direct fibrosis markers that do not involve transaminases [27], of which ITIH4 can be considered as one.
Hematological and serum biochemical profiling Hematological parameters viz., blood glucose level, mean corpuscular volume (MCV), packed cell volume (PVC), total red (TRBC) and white blood cell (TWBC) count and serum biochemical parameters such as cholesterol, aspartate transaminase (ASAT), alanine transaminase (ALAT), high density lipoprotein (HDL), low density lipoprotein (LDL), total protein and triglycerides were determined in blood samples by using Hitachi 902 automatic analyzer (Japan) following Khan et al.
Estimations of Aspartate transaminase 12, 13, 14 Alanine transaminase 13, 15, 16 Gamma glutamyl transferase 17, 18 were done by IFCC recommended methods on Dimension Clinical chemistry system (auto analyzer).
Linear regression models were fitted for In-transformed values of alanine transaminase (ALT), [gamma]-glutamyltransferase, and direct bilirubin on PFOA, PFOS, and potential confounders, and logistic regression models were used to compare deciles of PFOA or PFOS in relation to high biomarker levels.
Blood parameters did not differ between males and females, except for aspartate transaminase values, which were significantly higher in females than males.
