Lactate production in skeletal muscle has now been studied for nearly two centuries and still its production and functional role at rest and during muscle contraction is a subject of debate. Historically, skeletal muscle was seen mainly as the site of lactate production during contraction and lactate production associated with a lack of muscle oxygenation and fatigue. Later, it was recognized t...

Distribution of lactate dehydrogenase (LDH) and succinic dehydrogenase (SDH) in the ovary of mice treated with two chronic doses of sodium fluoride (NaF), for five days, in drinking water. LDH histochemical reactivity was observed following Hess et al., (1958) technique and SDH histochemical reactivity was obtained using the method of Nachlas et al., (1957). A decreasing trend of enzyme reactiv...

The diagnosis of Creutzfeldt-Jakob disease (CJD) is still made by exclusion of other dementias. We now evaluated lactate dehydrogenase (LDH) in the cerebrospinal fluid (CSF) as a possible additional diagnostic tool. CSF LDH levels of patients with CJD (n = 26) were compared with those in other dementias (n = 28). LDH isoenzymes were determined in a subset (n = 9). Total LDH and isoenzyme LDH-1 ...

Streptococcus mutans JC 2 produced mainly lactate as a fermentation product when grown in nitrogen-limited continuous culture in the presence of an excess of glucose and produced formate, acetate, and ethanol, but no lactate, under glucose-limited conditions. The levels of lactate dehydrogenase (LDH) in these cultures were of the same order of magnitude, and the activity of LDH was completely d...

Objective: Meningitis is life-threatening condition and examination of the Cerebrospinal fluid (CSF) may not give a precise diagnosis and prognosis of different types of meningitis. Bacterial meningitis is still a very common problem especially in many developing countries. The aims of study are to estimate the importance and significance of Lactate Dehydrogenase (LDH), protein...

the present study was aimed to evaluate the therapeutic potential of pimpinella tirupatiensis (pt) by assaying the activities of selective mitochondrial enzymes in streptozotocin induced diabetic rats. diabetic rats showed a significant (p < 0.01) reduction in the activities of oxidative enzymes succinate dehydrogenase (sdh), malate dehydrogenase (mdh), glutamate dehydrogenase (gdh) and isocitr...

In the asexual stages, Toxoplasma gondii stage converts between acute phase rapidly replicating tachyzoites and chronic phase slowly dividing bradyzoites. Correspondingly, T. gondii differentially expresses two distinct genes and isoforms of the lactate dehydrogenase enzyme, expressing LDH1 exclusively in the tachyzoite stage and LDH2 preferentially in the bradyzoite stage. LDH catalyzes the in...

A study was conducted to evaluate the effects on blood lipids and lipoproteins of feeding 21 healthy volunteers, 40-60 yr old, foods commonly eaten in the United States for two 40-day periods. Activities of lactate dehydrogenase (LDH) and LDH isoenzymes, lactate, and pyruvate were monitored. Results showed that LDH activity was significantly lower in all subjects at the end of the 25% fat-calor...

Here, we report a 28-year-old woman who transiently showed lactate dehydrogenase (LDH)-linked immunoglobulin during postpartum thyroiditis. She demonstrated high levels of serum LDH (794 IU/l) and thyroid hormones 7 months after delivery. Electrophoretic isoenzyme analysis of LDH showed an abnormal broadband caused by LDH-linked immunoglobulin (IgG-kappa). Transient thyrotoxicosis due to postpa...
