The creatine kinase and lactate dehydrogenase isoenzyme pattern were determined in the serum of normal and untreated rats, rabbits, dogs, monkeys and pigs. The relative distribution of all isoenzymes in the serum and an electrophoretic pattern for each animal species are presented. The isoenzyme serum pattern showed a great variation between the species. The diagnostic value of serum creatine k...

Abnormal electrophoretic pattern of serum lactate dehydrogenase isoenzyme is shown. In this case electrophoretic pattern showed a sharp single band between lactate dehydrogenase 4 and lactate dehydrogenase 5 and broad band between lactate dehydrogenase 2 and lactate dehydrogenase 4. This abnormality was suggested to be caused by the presence of lactate dehydrogenase and immunoglobulin G (kappa ...

CD4+ T cells are sensitive to peripheral changes of cytokine levels and metabolic substrates such as glucose lactate. This study aimed analyze whether factors released after exercise alter parameters human cell metabolism, specifically glycolysis oxidative phosphorylation. We used primary activated in the presence autologous serum, which was collected before (CO) a 30-min intervention (EX). In ...

OBJECTIVES To test for structural and functional contribution of mitochondrial dysfunction to neurodegeneration in multiple sclerosis (MS). A visual pathway model void of MS lesions was chosen in order to exclude neurodegeneration secondary to lesion related axonotmesis. METHODS A single-centre cohort study (230 MS patients, 63 controls). Spectral domain optical coherence tomography of the re...

BACKGROUND AND AIMS An association of high lactate levels with mortality has been found in adult patients with septic shock. However, there is controversial literature regarding the same in children. The aim of this study was to find the correlation of serum lactate levels in pediatric septic shock with survival. SETTINGS AND DESIGN This was a prospective observational study at PICU of a tert...

OBJECTIVE To assess the correlation between plasma lactate concentrations in the first 6 hours of life and early neonatal mortality. METHODS The patients were divided in 2 groups based on the cutoff point, obtained from a receiver operating characteristic (ROC) curve, of the plasma lactate concentration that best predicted neonatal mortality during the first 3 days of life. The differences be...

AIM To investigate whether the short-term prognosis of hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) could be improved by using a modified model for end-stage liver disease (MELD) including serum lactate. METHODS This clinical study was conducted at the First Affiliated Hospital, Fujian Medicine University, China. From 2009 to 2015, 236 patients diagnosed with HBV-rela...

We describe the use of a continuous-flow clinical analyzer with an immobilized coupled-enzyme nylon tube reactor and an immobilized single-enzyme nylon tube reactor for routine estimation of lactate and pyruvate in serum. These reactors are incorporated into the flow system of a modified continuous-flow analyzer (Technicon AutoAnalyzer). Results for serum lactate and pyruvate by this method are...

Lactate dehydrogenase (LD: EC 1.1.1.27) is the most important clinically of several dehydrogenases occurring in human serum. Lactate dehydrogenase is cytoplasmic in its cellular location and in any one tissue is composed of one or two of five possible isoenzymes. While many of its clinical applications involve quantification of one or more specific serum isoenzymes, an estimate of total LD is r...
