The variation of lactate dehydrogenase, peroxidase, acid and alkaline phosphatase isoenzymes was studied in VERO cells inoculated with infectant and UV-inactivated herpes simplex virus type 1 (HSV--1). Infectant HSV--1 induced quantitative and qualitative modifications in isoenzyme patterns within the first 4 hours post inoculation (p.i.). The modifications caused by the UV-inactivated HSV--1 were similar, but appeared 8 hours p.i. The possibility of using isoenzyme modifications as rapid, sensitive and specific biochemical tests for virus detection and differentiation between infectant and inactivated virus is discussed.

Twelve pigs which averaged 13.7 kg were randomly allotted from litters to a corn-soybean meal grower diet containing 0, 20, or 200 ppm of polybrominated biphenyls (PPB). During a 16-week growth trial, average daily gain (kg), average daily feed (kg) and feed/gain for pigs on diets containing 0, 20, or 200 ppm of PBB, respectively, were 0.82, 2.45, 2.99; 0.67, 1.88, 2.79; 0.45, 1.23, 2.70. Mean daily gain differences between all lots were highly significant (p < 0.01). Blood from each pig was withdrawn biweekly through the first 8 weeks of the trial and at 4 week intervals thereafter. Hemoglobin and hematocrit differed significantly only at the 6 weeks bleeding, being reduced in pigs receiving 200 ppm of PBB. Erythrocyte reduced glutathione concentration and glutathione peroxidase activity were not significantly influenced by level of dietary PBB. Serum lactic dehydrogenase activity was significantly higher in control pigs than in either PBB supplemented lots at 16 weeks. There was no significant influence of PBB upon serum glutamic oxaloacetic transaminase, serum alkaline phosphatase or serum creatine phosphokinase. Based on these enzyme assays, PBB produced no evidence of significant necrosis of liver, myocardium, or skeletal muscle. There was no consistent effect of dietary PBB upon total serum protein concentration or electrophoretic profile. Pigs on either level of PBB did not have overt clinical signs of toxicity during the 16-week test period with the exception of a dermatosis on the ventral surface of two of the pigs receiving 200 ppm of PBB. There was a marked increase in liver weight of pigs receiving either level of dietary PBB. Heart, kidney, and adrenals of pigs receiving either level of dietary PBB were heavier as a percent of body weight than that of control pigs. Fat retention of PBB and urinary and fecal PBB excretion were significantly affected by dietary PBB level. Grossly, the glandular portion of the stomach appeared somewhat hyperplastic in pigs on 200 ppm of PBB. Two pigs which had received 200 ppm of PBB were placed on the control diet and over the next 14 weeks normal growth rate occurred. One of these pigs was killed and organ weights were normal. The other pig, a gilt, came into estrus. She was bred and conceived. At the end of gestation, four pigs were born. Three survived and grew normally; the one death at birth examined at gross necropsy did not reveal changes in organ size or other tissue alterations.

Histological studies showed that the administration of p-nitrophenylarsonic acid to rats resulted in renal tubular necrosis. The nephrotoxin was administered intraperitoneally and doses greater than 30 mg/kg were found to be fatal. The severity of the renal lesion depended on the amount of the nephrotoxin used. Elevated serum urea levels, urinary protein and volume were recorded over an 8-day period following the injection of the nephrotoxin. These changes were paralleled by an increase in the activity of lactate dehydrogenase, acid and alkaline phosphatase, N-acetyl-beta-glucosaminidase and beta-glucosidase in the urine. beta-Glycosidase activities increased in kidney homogenates, immediately after the injection of the nephrotoxin, but this eventually fell to well below the normal range. Subcellular fractions were prepared from sucrose homogenates by differential centrifugation and beta-glycosidases and cytochrome oxidase were used as enzyme markers. Only minor changes in the activity of cytochrome oxidase activity resulted from the administration of p-nitrophenylarsonic acid. One of the earliest indications of renal damage was a decrease in lysosomal latency. The activities of the lysosomal and soluble enzymes were elevated above normal during the first two days after the injection of p-nitrophenylarsonic acid, but they fell to values, significantly lower than normal, on the third day. The isoenzymic forms of beta-galactosidase, beta-glucosidase and N-acetyl-beta-glucosaminidase in normal and damaged kidneys were studied, using starch gel electrophoresis. The activities of both the lysosomal and the soluble forms of these enzymes decreased following the injection of the nephrotoxin, confirming the results obtained with whole homogenates. The relationship between the changes in renal enzyme activity and urinary enzyme excretion during the nephrotoxic process is discussed.

Lactate dehydrogenase and alkaline phosphatase activities in the same medium can be determined simulataneously, at 350 and 550 nm, with a vidicon spectrometer. Substrate concentrations and ph have been made optimum for the combined analysis. These conditions result in activities for lactate dehydrogenase that are equivalent to those found by methods in common use, and activites for alkaline phosphatase that are about 31% below the maximum values that could be obtained with its substrate used at the same ph and temperature in the absence of NAD+ and lactate. However, activites measured by the simultaneous analysis were proportional to those obtained by other methods used in clinical laboratories, and the coefficients of variation were 2.3% for lactate dehydrogenase and 3% for alkaline phosphatase.

In 30 patients with histologically verified malignant liver processes, the authors have examined the value of the serum activity of liver lactate dehydrogenase (LDH), alkaline phosphatase and gamma-glutamyltranspeptidase and in a number of patients, 5'-nucleotidase. These values were compared with the findings received from scintigraphy of the liver. Based on the results obtained, the authors have concluded that the activities of the gamma-glutamyltranspeptidase (gammaGT), 5'-nucleotidase and liver lactate dehydrogenase are more significantly increased in malignant processes of the liver than scintigraphy of the liver could register.

The effect of boseimycin on the in vitro activity and in vivo synthesis of alkaline phosphatase, aconitase and lactate, isocitrate, glutamate and alanine dehydrogenases was studied in Bacillus subtilis. At a subinhibitory concentration, synthesis of glutamate dehydrogenase was stimulated but alkaline phosphatase, lactate dehydrogenase and aconitase synthesis was inhibited. On the contrary, boseimycin inhibited slightly the activity of lactate dehydrogenase in cell-free extracts. Glutamate dehydrogenase and aconitase activities were not affected.

56 human liver biopsy specimens with insignificant or no histological changes, but with abnormally strong canalicular alkaline phosphatase activity, were studied histochemically for other enzyme changes. In comparison with normal specimens, more extensive and increased canalicular activity of gamma-glutamyl transferase, and increase of canalicular leucine aminopeptidase, was found, while the sinusoidal activity of the latter enzyme was decreased. Staining for adenosine triphosphatase regularly desclosed the normal pattern of sinusoidal and canalicular activity. The lysosomal enzymes, acid phosphatase and beta-glucuronidase, stained more intensely than ordinarily, while the reactions for enzymes present in the cytosol (lactic dehydrogenase), in the mitochondria (succinic dehydrogenase, imonoamine oxidase) and in the endoplasmic reticulum (glucose-6-phosphatase) were normal.

A case of fatal viscerotropic Rocky Mountain spotted fever with virtual absence of cutaneous lesions was diagnosed at autopsy by specific immunofluorescent demonstration of Rickettsia rickettsii in spleen, kidney, epididymis and skin. The clinical presentation was that of insidious onset of fever, renal failure, hypotension, hyponatremia and obtundation over a 10 day period. The patient had respiratory insufficiency, hypocalcemia, increases in creatinine phosphokinase (CPK), serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), lactic dehydrogenase (LDH), alkaline phosphatase, billirubin and serum phosphate, grand mal seizure, myalgia and unremitting shock with death occurring on day 12 of illness. Postmortem examination revealed severe vasculitis with interstitial nephritis and multifocal tubular necrosis, pericholangitis with bile stasis, glial nodules in the brain, multifocal rhabdomyonecrosis, interstitial pneumonitis and mild interstitial myocarditis. Risk factors which this patient shared with other patients with fatal Rocky Mountain spotted fever were failure to recognize a rash, failure to obtain a tick bite history, male sex, black race and age greater than 30 years.

In recent years the determination of serum enzyme activities has played an increasing role in clinical chemical diagnosis. Because the enzyme composition of single organs is qualitatively and, to a certain extent, quantitatively similar, the diagnostic value of enzyme activity determinations is often diminished. Each serum enzyme can be separated into isoenzymes which stem from different organs and make specific organ diagnoses possible. This separation is possible through chemico-physical and immunological methods. Electrophoretic, chromatographic and immunological methods for the determination of creatine phosphokinase isoenzymes the immunological method is superior to the electrophoretic method in precision and accuracy. Artefacts through storage do not occur in the immunological method. New aspects of the clinical value of the determination of isoenzymes of alkaline phosphatase (AP, E.C. 3.1.3.1), creatine phosphokinase (CK, E.C. 2.7.3.2) and lactate dehydrogenase (LDH, E.C. 1.1.1.27) were studied in the following 8 patient groups: 1. The value of AP isoenzymes for determining liver damage due to chronic alcoholism. 2. The distribution of AP isoenzymes in dialysis patients with special regard to the intestinal isoenzyme. 3. The immunological demonstration of carcino-placental antigen of AP in tumours of the lung. 4. The demonstration of intestinal isoenzymes of AP in chylous effusions. 5. The profile of LDH isoenzymes in pulmonary alveolar proteinosis in serum and in lung lavage-fluid. 6. The usefulness of CK-MB isoenzyme as proff of cardiotoxicity of pharmaceuticals. 7. The profile of CK isoenzymes in central and peripheral nervous system diseases, especially the appearance of CK-BB in serum and the behaviour of CK at the blood spinal fluid barrier. 8. The appearance of unusual isoenzyme patterns in newborn infants and in pregnant women in comparison with normal adults. The determination of isoenzymes is of great clinical importance, even if the total serum activity of the particular enzyme is not elevated.

1. The activity of dopamine-beta-hydroxylase (DBH) was assayed in the serum of 102 patients, mostly with varying degrees of hepatic dysfunction. 2. DBH activity was not elevated in those with liver disorder and did not correlate with serum bilirubin, transaminase, lactic dehydrogenase, alkaline phosphatase or creatine phosphokinase. 3. It is concluded that the liver is not necessarily involved in the inactivation of DBH.
