Chemical parameters comprising urea and creatinine nitrogen, cations (Na+, K+, and Ca2+), chloride, phosphorus, protein, cholesterol and enzymes, aminotransferases, alkaline and prostatic acid phosphatases, gamma-glutamyltransferase, creatine kinase, and lactate dehydrogenase were ascertained for semen from groups A (vasectomized), B (oligospermic), and C (normospermic) men, 19 to 55 years of age. Of the parameters, the vasectomized group underwent definite depressions in potassium ion, alkaline phosphatase, aspartate aminotransferase, gamma-glutamyltransferase, and lactate dehydrogenase as compared with the normospermic group; the last three enzymes and, possibly, the urea-creatinine ratio were decreased for the oligospermic group vs. the normospermic men. In the comparison of groups A and B, only the decrements in alanine aminotransferase and lactate dehydrogenase were statistically significant. In corroboration of past reports, CK-BB comprised the main isoenzyme of semen creatine kinase.

727 consecutive drunken drivers were studied for laboratory markers of excessive alcohol consumption. Serum gamma-glutamyltransferase and alanine aminotransferase showed no differences and aspartate aminotransferase and blood alcohol concentration only small differences between groups of first and repeating drunk driving offenders. The best laboratory test to differentiate the repeating offenders with probably more serious alcohol problems from the first offenders was in our material serum acetate, the mean serum acetate level of the repeating offenders being highly significantly (P less than 0.001) higher than that of the first offenders or nonalcoholic controls. Serum acetate also differentiated first offenders from nonalcoholic controls (P less than 0.001). Our results suggest that serum acetate could be used for the screening of problem drinking among drunken drivers.

Concentrations of sodium, potassium, chloride, inorganic phosphorus, total magnesium, total calcium, iron, urea, creatinine, total protein, albumin, total bilirubin, alkaline phosphatase (ALP), alanine transaminase (ALT), lactate dehydrogenase (LD), creatine kinase (CK), gamma-glutamyltransferase (GGT) and aspartate transaminase (AST) were determined in serum specimens collected from 53 free-ranging mountain reedbuck (Redunca fulvorufula) during live capture using nets. Considerable variations in the concentrations of the enzymes ALP, LDH, CK, GGT and AST were found as well as in the concentrations of creatinine, bilirubin and iron. This wide variation in results seriously questions the usefulness of similar blood investigations on heterogenous groups of mechanically restrained animals.

Concentrations of sodium, potassium, chloride, inorganic phosphorus, total calcium, total magnesium, albumin, total protein, cholesterol, urea, creatinine, cortisol as well as the activities of alkaline phosphatase, alanine transaminase, aspartate transaminase, gamma-glutamyltransferase, creatine kinase and lactate dehydrogenase were determined in serum specimens collected from 100 free-ranging warthogs Phacochoerus aethiopicus within five minutes after they were killed with a shotgun. Average concentrations for the following chemical constituents were found: sodium (145 mmol l-1), potassium (8.6 mmol l-1), chloride (102.5 mmol l-1), phosphorus (2.31 mmol l-1), calcium (2.93 mmol l-1), magnesium (1.23 mmol l-1), albumin (26.4 g l-1), serum proteins (62.2 g l-1), cholesterol (1.82 mmol l-1) and urea (8.74 mmol l-1). The cortisol concentrations ranged from 55-340 nmol l-1 (n = 30). Wide variations were recorded in the concentration of creatinine as well as in the activities of the various enzymes.

The authors evaluated the Cobas FARA centrifugal analyzer with respect to pipetting precision and accuracy, instrument temperature, spectrophotometric response, and analytic performance for the assay of five serum enzymes and glucose. Spectrophotometric response, temperature response, pipetting precision, and accuracy were satisfactory. However, sufficient time must be allowed for cuvet contents to reach a stable temperature before measurements are made. Total day-to-day imprecision (within plus between run) was less than 5% (coefficient of variation) for aspartate and alanine aminotransferases (AST; Enzyme Commission classification number [EC] EC 2.6.1.1; and ALT; EC 2.6.1.2); alkaline phosphatase (AP; EC 3.1.3.1); gamma-glutamyltransferase (GGT; EC 2.3.1.2); lactate dehydrogenase (LD; EC 1.1.1.17); creatine kinase (CK; EC 2.7.3.1); and glucose assays. Results compare well with those obtained with other current clinical chemistry analyzers; correlation coefficients were greater than 0.993. Sample-to-sample carryover was negligible, and method linearity was satisfactory for all tests.

A rapid selective method for measuring the activity of lactate dehydrogenase isoenzyme LD-1 in serum by using 1,6-hexanediol as an inhibitor of the M-subunit was developed. Hexanediol was added to serum at a final concentration of 0.7 mol/l. After incubation at 30 degrees C for 15 min, the activity was measured with an automatic analyser. The inter-assay coefficient of variation was 6.9% for the lactate dehydrogenase isoenzyme LD-1 measurement. The results obtained from the sera of 100 patients analysed by the proposed selective method and by the conventional electrophoretic method, respectively, showed an excellent correlation. This selective method was used to determine the lactate dehydrogenase isoenzyme LD-1 activity of sera from patients with acute myocardial infarction, and the results were correlated well with those obtained by the immunological, Roch Isomune method. Addition of 1,6-hexanediol did not affect the measurement of activities of other enzymes such as alkaline phosphatase, gamma-glutamyltransferase, aspartate aminotransferase and alanine aminotransferase.

Using fully mechanized analytical equipment, interference by haemolysis in the determination of 26 clinical chemical parameters was determined quantitatively by adding haemolysate to serum. Haemoglobin concentrations up to 6.6 g/l caused essentially no interference in the following determinations: albumin (immuno-nephelometric), alpha-amylase, calcium, chloride, cholesterol, cholinesterase, creatinine, iron, glucose, glutamate dehydrogenase, uric acid, urea, sodium, inorganic phosphate, total protein, transferrin and triglycerides. In the presence of haemoglobin, erroneously high values were found for: lactate dehydrogenase (haemoglobin higher than 0.2 g/l), aspartate aminotransferase, potassium and acid phosphate (haemoglobin higher than 1.5 g/l), creatine kinase (haemoglobin higher than 2.5 g/l) and alanine aminotransferase (haemoglobin higher than 3.4 g/l). Erroneously low values were found for bilirubin (haemoglobin higher than 0.8 g/l), alkaline phosphatase and albumin (by electrophoresis) (haemoglobin higher than 1.5 g/l) and gamma-glutamyltransferase (haemoglobin higher than 3.0 g/l).

Previous observations that valproic acid (VPA) causes hepatic damage prompted us to investigate the effect of large doses of the drug (0.6, 1.2 and 1.8 mmol/kg/day) on a number of liver enzymes located on different subcellular fractions. In mitochondria, glutamate dehydrogenase, aspartate aminotransferase and ornithine carbamoyltransferase were significantly increased (1.8 mmol/kg/day). In microsomes, gamma-glutamyltransferase activity increased significantly (1.8 mmol/kg) and cytochrome P-450 content decreased significantly (1.2 and 1.8 mmol/kg). In cytosol, both aspartate and alanine aminotransferase activities were increased at all dose levels. These results indicate that VPA induces dose-dependent changes in some liver enzyme activities.
