Fibroblasts could be considered as connective tissue cells that are morphologically heterogeneous with diverse functions depending on their location and activity. These cells play critical role in health and disease such as cancer and wound by Production of collagen, fibronectin, cytokines and growth factors. Absence of insulin and other growth factors in serum deprivation condition and similar...

THIRTY STRAINS OF HUMAN ORAL ANAEROBIC SPIROCHETES WERE ISOLATED IN THREE DIFFERENT MEDIA: veal heart infusion-ascitic fluid, Spirolate-Brain Heart Infusion-rabbit serum, and supplemented PPLO broth. The morphological and biochemical characteristics of the isolates permitted their differentiation into three distinct species: Treponema denticola, T. macrodentium, and T. oralis (proposed new spec...

Diagnosis of injury to the myocardium is facilitated by information on the activities of creatine kinase (EC 2.7.3.2) MB isoenzyme (CK-MB) and lactate dehydrogenase (EC 1.1.1.27) isoenzyme 1 in serum, these isoenzymes being present in higher activities in the myocardium than in other tissues or in normal serum. The temporal relationships of these isoenzymes, total creatine kinase, total lactate...

BACKGROUND Mitochondrial toxicity was described in infants exposed to long-term antiretroviral regimens containing nucleoside analogues for the prevention of mother-to-child transmission of HIV. We measured the serum lactate levels in children born to HIV-1 infected African women receiving short-term antiretroviral prevention of mother-to-child transmission of HIV regimens. METHODS A prospect...

We were interested to read the article by Manini et al. (1), which confirmed previous observations that a severe ethylene glycol poisoning may lead to falsely elevated lactate levels (2). High lactate levels were indeed measured by enzymatic spectrophotometry (Integra analyzer) but excluded by a specific GC analysis. A linear correlation was nicely demonstrated between the serially determined b...

Dichloroacetate (DCA) is known to prevent the phosphorylation of the pyruvate dehydrogenase complex (PDHC) by blocking the action of PDH kinase. This action allows the active PDHC to exert its effect on the metabolism of glucose, lactate and alanine to acetyl CoA. DCA has been shown to reduce serum lactate levels in humans and animals in such conditions as diabetes, phenformin-induced hepatic f...

BACKGROUND The aim of this study was to determine if the post-operative serum arterial lactate concentration is associated with mortality, length of hospital stay or complications following hepatic resection. METHODS Serum lactate concentration was recorded at the end of liver resection in a consecutive series of 488 patients over a seven-year period. Liver function, coagulation and electroly...

OBJECTIVE To assess the value of sequential lactate measurement in predicting postoperative mortality after surgery for complex congenital heart disease in children. DESIGN Prospective observational study. SETTING Sixteen bedded paediatric intensive care unit (PICU). SUBJECTS Ninety nine children (90 survivors, nine non-survivors). MEASUREMENTS Serum lactate and base deficit were measur...
