This review describes the usefulness of monitoring the activity level of lactate dehydrogenase (LDH) and its isoenzyme pattern as indicators of pathological conditions in the lungs, such as cell damage or inflammation. Cytoplasmatic cellular enzymes, like LDH, in the extracellular space, although of no further metabolic function in this space, are still of benefit because they serve as indicato...

In this study, oxidative energy metabolism was determined in 5 captive bottlenose dolphins (Tursiops truncatus), and subsequently compared to 6 Thoroughbred riding horses, and 12 lactating Holstein cows in order to assess symmorphosis of each animal species. Plasma metabolites profile, plasma MDH (M) and LDH (L) activities, M/L ratio, and plasma LDH isoenzyme distribution patterns were all exam...

Low lactate dehydrogenase (LD; EC 1.1.1.27) activity and an abnormal LD pattern in electrophoretograms of LD isoenzymes in the sera of two patients were caused by inhibition of LD by immunoglobulin G. One of these showed inhibitor activity in the serum upon direct analysis, while the other showed activity only after the immunoglobulin was stripped from the LD. As judged from the LD isoenzyme pa...

Serum lactate dehydrogenase (LDH) activity, a marker of cell damage, is increased in several pulmonary disorders, especially when fibrosis is involved. In rats exposed to silica, high levels of LDH activity were found. A rise of serum LDH3 has been associated with lung tissue injury. The aim of this study was to investigate the serum LDH isoenzyme pattern after coal-dust exposure and the possib...

Thirteen electrophoretic bands of lactate dehydrogenase isoenzyme activity were detected in the serum of a 69-year-oldNegro woman who died of pseudomonas pneumonia. No evidence of tumor was found at necropsy, and additional studies of the enzymatic activity of crude extracts of liver, lung, spleen, kidney, brain, skeletal muscle, lymph node, and heart revealed 1, 2, 3, 4, and 5 separate lsoenzy...

The electrophoretic pattern (in polyacrylamide gel) for acid phosphatases in the prostate gland was compared with that for other tissues. lsoenzyme 2 predominates in the prostate. The isoenzyme was isolated from the prostate and its biochemical properties were compared with those of acid phosphatases isolated from spleen. lsoenzyme 2 has a molecular weight of about 100,000. Its optimum pH is be...

Urinary N-acetyl-beta-glucosaminidase (NAG) and its isoenzymes (NAG A and NAG B) in samples from 87 type 1 diabetic patients and 40 apparently healthy reference subjects were studied with enzyme immunoassays. The diabetic patients had higher concentrations of urinary NAG than did the control subjects (P less than 0.01), but the isoenzyme pattern did not differ. There was a positive correlation ...
