Guinea pigs infected with 9-mile phase I strain of Coxiella burnetii had increased blood glucose concentrations; alkaline phosphatase (ALP), glutamic-oxalacetic transaminase (GOT), alpha-hydroxybutyrate dehydrogenase (alpha-HBDH), and creatine phosphokinase (CPK) activities; and bilirubin value. Hypocalcemia and hypophosphatemia were evident in the latter days of infection. At necropsy of the guinea pigs, necrotic foci were in liver, spleen, and heart. Seemingly, the major pathophysiologic changes in infected guinea pigs were the direct result of lesions in liver, spleen, and heart in which rickettsial bodies were readily observable with histologic staining procedures. The guinea pig may serve as an animal disease model for Q fever.

We have recently utilized a prototype model of the Beckman Enzyme Activity Analyzer System-TR in our laboratory measuring various serum enzyme activities which include: alkaline phosphatase (ALP), E.C.3.1.3.1; creatine kinase (CK), E.C.2.7.3.2; hydroxybutyrate dehydrogenase (HBD), E.C.1.1.1.30; lactate dehydrogenase (LD), E.C.1.1.1.27; aspartate transaminase (AST), E.C.2.6.1.1; and alanine transaminase (ALT), E.C.2.6.1.2. Precision was found to be good. Sample activities could be measured as high as 1000 IU/1. The carryover studies fell within 2 SD of the means of the enzyme control studies. Coefficients of variation for ALP and CK were in the ranges of 0-40-2-14% and 0-52-4-30%, respectively. Correlation studies were done with GemSAEC and Gilford 300 N Spectrophotometer and the results were accurate, precise, and reproducible.

Doping with tranquilizers has appeared recently in horse-back riding sports. In this paper we study the effects of acepromazine, one of the main tranquilizers used, on various physiological and biochemical aspects of muscular activity (cardiac and respiratory rhythms, seric rates of glucose, urea, protein, creatine phosphokinase, glutamate oxalacetate transaminase, alkaline phosphatase). A low dose (0.02 mg/kg) of acepromazine is injected; the evolution of the variables is studied before and after a standardized effort. After the effort and during recuperation, acepromazine administration causes: -- a decrease of respiratory rhythm and seric protein rats, -- an increase of creatine phosphokinase rate. A discussion of these results suggests that acepromazine depresses the respiratory centers and has a possible toxic effect on the muscle cell.

In a study of 4-hr hemorrhagic hypotension in dogs, the plasma levels of the lysosomal enzymes, cathepsin (CATH) and acid phosphatase (AP) showed early and progressive increases in activity. The plasma levels of the intestinal fraction of alkaline phosphatase (IAkP) and aspartate aminotransferase (AAT) were increased after 2 hr of hypotension and the liver specific enzyme, ornithine carbamyltransferase (OCT), and creatine phosphokinase (CPK), after 3 hr. All of the enzymes showed large increases after 4 hr of hypotension. The plasma levels of CATH showed the earliest and largest relative increase indicating that with the shock model used, this enzyme was the most sensitive indicator of shock severity. The increase in plasma enzyme levels was probably the result of tissue damage in the splanchnic region but the elevation of plasma CPK, a muscle specific enzyme, indicates some muscle cell damage as well. While the increase in the plasma enzyme activity is probably due, in large part, to cellular damage, it is likely that a decreased enzyme removal rate--resulting from a hypofunctional RES--also contributes to the elevated plasma enzyme levels during hemorrhagic hypotension.

The activities of aspartate aminotransferase (GOT), alanine aminotransferase (GPT), alkaline phosphatase (alkP), creatine kinase (CPK), and ornithine carbamoyltransferase (OCT) were determined in liver, heart, skeletal muscle, brain, kidney, lung, spleen, adrenals, pancreas, thyroid, thymus, and red cells of 56 bovine fetuses varying in gestational age from 115 to 255 days. The tissue aminotransferase activities were the most variable with gestational age. The GPT activity of liver, kidney, spleen, and red cells and the GOT activity of red cells decreased with fetal age. The GPT activity of heart, brain, and skeletal muscle and the GOT activity of adrenal, brain, and skeletal muscle increased with fetal age. Increasing activities were also described for adrenal and brain alkP and for brain and skeletal muscle CPK. In contrast, the OCT activities were fairly constant for each tissue as a function of gestational age.

Biochemical variables have been measured in a group of volunteers during and after a long-distance run. Plasma glucose levels remained relatively constant and a significant decrease in plasma bicarbonate was noted. Plasma sodium, chloride, total protein, albumin and calcium showed significant increased of an order compatible with water losses occurring during the run. Plasma potassium, urea, creatinine, uric acid, phosphate and bilirubin all show much more marked and variable increases. The plasma enzymes alkaline phosphatase, lactate dehydrogenase, aspartate aminotransferase and creatine kinase likewise increased significantly throughout the run. Whilst most constituents showed a tendency to return to normal at 20-30 hours after the run, gross increases were observed for aspartate aminotransferase and creatine kinase.

Thirty patients are described who developed jaundice during the course of severe bacterial infection. Although the infecting organism was variable, as was the site of infection, the patients were generally ill and pyrexial. The group had a very high mortality rate (43%). A positive blood culture was obtained in 11 patients. Biochemical abnormalities noted were those of an increased concentration of conjugated bilirubin in the serum with only a modest increase in alkaline phosphatase and transaminase levels. Serum cholesterol was found to be normal. The mean serum urea level was significantly elevated, as were creatine phosphokinase and lactic dehydrogenase. Most patients exhibited a neutrophil leukocytosis and an elevated sedimentation rate, and the mean hemoglobin level was low. Liver histology was studied in 13 patients. There was evidence of mild bile stasis in 5 and moderate bile stasis in 2. Findings were otherwise nonspecific and were characterized by fatty change and/or inflammatory cells in the portal areas. There was no correlation between degree or duration of juandice and prognosis, although all patients who died remained jaundiced until death. It is suggested that this syndrome is not one of true cholestasis in that all biliary substances were not shown to be elevated in the serum, but that it is rather a selective defect in the excretion of conjugated bilirubin.

Blood samples were collected from 91 rusa deer (Cervus timorensis russa), immediately after being shot. Serum mean biochemical values from shot deer are presented for blood urea nitrogen, creatinine, creatine kinase, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin, total protein, albumin, calcium, and phosphorus. Mean total protein and albumin increased with age. There was an age-associated increase of gamma globulins. Mean creatine kinase activity and creatinine, albumin and phosphorus concentrations were higher in stags than in hinds. Pregnant hinds had lower mean creatine kinase activity and phosphorus and higher mean alanine aminotransferase and total protein than non-pregnant hinds. Mean calcium concentration increased when deer were agitated before bleeding.

The critical difference, which may help to judge whether the difference between two consecutive analytical results may be safely ascribed to natural variation or not, was calculated for 12 clinical chemical components determined in blood samples collected once a week for 5 consecutive weeks from 19 clinically healthy Red Danish dairy cows. For each clinical chemical component, the total variance of the analytical results was divided into the component of variance between cows (S2Inter), the component of variance for weeks within cows (S2Intra) and the component of variance for measurements (S2Anal) using nested analysis of variance. The critical difference calculated in absolute values from S2Intra and S2Anal was 0.15 mu kat per 1 for alanine aminotransferase, 0.55 mu kat per 1 for aspartate aminotransferase, 0.57 mu kat per 1 for alkaline phosphatase, 0.14 mu kat per 1 for gamma-glutamyltransferase, 1.95 mu kat per 1 for creatine kinase, 2.23 mmol per 1 for urea, 22 mu mol per 1 for creatinine, 2.4 g per 1 for albumin, 10.0 g per 1 for serum protein Total, 0.71 mmol per 1 for glucose, 0.54 mmol per 1 for calcium and 0.25 mmol per 1 for magnesium. These critical differences may be used as guidelines to evaluate the difference between two consecutive analytical results in cows. However, the analytical results should not be assessed by the critical differences alone, but should also be compared with the corresponding reference intervals.

Ubiquinol-1 in aerated aqueous solution inactivates several enzymes--alanine aminotransferase, alkaline phosphatase, Na+/K(+)-ATPase, creatine kinase and glutamine synthetase--but not isocitrate dehydrogenase and malate dehydrogenase. Ubiquinone-1 and/or H2O2 do not affect the activity of alkaline phosphatase and glutamine synthetase chosen as model enzymes. Dioxygen and transition metal ions, even if in trace amounts, are essential for the enzyme inactivation, which indeed does not occur under argon atmosphere or in the presence of metal chelators. Supplementation with redox-active metal ions (Fe3+ or Cu2+), moreover, potentiates alkaline phosphatase inactivation. Since catalase and peroxidase protect while superoxide dismutase does not, hydrogen peroxide rather than superoxide anion seems to be involved in the inactivation mechanism through which oxygen active species (hydroxyl radical or any other equivalent species) are produced via a modified Haber-Weiss cycle, triggered by metal-catalyzed oxidation of ubiquinol-1. The lack of efficiency of radical scavengers and the almost complete protection afforded by enzyme substrates and metal cofactors indicate a 'site-specific' radical attack as responsible for the oxidative damage.
