Investigations were carried out on the serum enzymes, total proteins and some electrolites (potassium and sodium) in eight spleenectomized sheep experimentally infected with Babesia organisms. It was found that babesiasis in sheep was accompanied by a considerable rise in the activity of GOT and GPT (from 80JU up to 260IU and from 4 IU up to 19 IU). The amount of inorganic phosphorus dropped, and that of potassium sodium and alkaline phosphatase showed no changes. It is believed that the changes in the activity of GOT, GPT and inorganic phosphorus depend on the gravity and the duration of the disease and can be used as a criterion in determining the pathologic process.

In the serum of 40 male and 40 female rats the following parameters were determined: Sodium, potassium, creatinine, chloride, calcium, inorganic phosphorus, glucose, urea, protein, cholesterol, bilirubin, lipids, alanine amino-transferase, alkaline phosphatase and leucine arylamidase. The analyses were carried out in the same rats both after continuous feeding, and after a 24-hour fasting periods spaced at intervals of 3- to 4-weeks. The concentration of glucose and the activities of alanine aminotransferase and alkaline phosphatase were higher after feeding than after fasting, and in most cases these differences were statistically significant. The concentration of lipids tended towards increased values. The other parameters examined were slightly or not influenced by the time of the foregoing feeding.

We sought to determine if there were any differences in the results of clinical laboratory tests between blood samples collected from the orbital venous plexus and the posterior vena cava of adult male rats. Thirty healthy adult male Sprague Dawley rats were anesthetized by ether inhalation, and blood samples were collected successively from the orbital venous plexus (OVP) and the posterior vena cava (PVC) for hematologic (n = 10), serum chemistry (n = 10), and coagulation (n = 10) analyses. The prothrombin and partial thromboplastin times of samples from the OVP were prolonged (17% and 288%, respectively) when compared with samples from the PVC. Respective hematologic biases were as follows: red blood cell count (7%), hemoglobin (6%), hematocrit (5%), mean corpuscular volume (-3%), mean corpuscular hemoglobin (-1%), mean corpuscular hemoglobin content (1%), white blood cell count (13%), and platelet count (-7%). Respective serum chemistry biases were as follows: sorbitol dehydrogenase (-7%), glucose (-7%), blood urea nitrogen (-10%), creatinine (-2%), total protein (4%), albumin (2%), globulin (9%), alkaline phosphatase (5%), lactate dehydrogenase (-6%), aspartate aminotransferase (-5%), alanine aminotransferase (-2%), total bilirubin (0%), direct bilirubin (0%), magnesium (-17%), sodium (4%), potassium (0), chloride (4%), calcium (-2%), phosphorous (-17%), cholesterol (3%), triglycerides (24%), creatinine kinase (-8%), 5'nucleotidase (0%), and total bile acids (4%). For hematologic testing, there were no biologically significant differences between samples collected from the OVP and PVC. The coagulation times and serum Mg and P showed biologically significant differences between samples collected from the OVP and PVC.(ABSTRACT TRUNCATED AT 250 WORDS)

The normal values (clinical references range) of the laboratory tests differs among hospitals due to the differences in: (1) the kinds of instruments and reagents used, (2) how the population for study was selected and the size of the population was, (3) when the specimens were taken, (4) how they were stored until use, and (5) how the data obtained were calculated and (6) who evaluated the results. In this study, questionnaires regarding the above-mentioned points were sent to the heads of the clinical laboratories in 80 university hospitals in Japan. Answers were received from 71 laboratories (the rate of recovery was 88.8%). The normal range of potassium, uric acid, total cholesterol, enzyme activities [ALP, LDH, CHE, AST (GOT) and ALT (GPT)] in the university hospitals in Japan varied. It is not ideal to use different reference values in different hospitals. However, it is impossible to prepare a standard manual to obtain the normal range at present. When the inter-hospital differences become small enough to obtain one normal range for the Japanese peoples, a standard manual for normal values should be made.

This report discusses a unique drug-induced hepatotoxicity in cynomolgus monkeys treated orally with a novel potassium sparing experimental diuretic, [2,6-bis(4-chlorophenyl)-4-pyridinecarboxylic acid]. Groups of 6 adult male and female monkeys were treated orally with vehicle diluent, modified vehicle #122 or a suspension of the drug at 5.0, 12.5, or 32.0 mg/kg/day for 2 weeks. Another group of 5 monkeys were treated orally with 25.0 mg/kg/day of the drug for 2 weeks. Disposition of the drugs was evaluated in 2 monkeys in the later group that received 27.4 mg/kg of radiolabelled drug on the 1st and last day of dosing. Hepatic toxicity was characterized biochemically, light and electron microscopically, histochemically, immunocytochemically, and toxico-kinetically. Conjugated serum bilirubin, alanine transaminase, and aspartate transaminase levels were increased in monkeys treated with over 12.5 mg/kg/day of the diuretic. The periacinar hepatic plates of monkeys treated with 25.0 or 32.0 mg/kg/day were distorted by accumulation of PAS and oil red-O positive multinucleated Kupffer cells. The cytosol of these cells was expanded by phagolysosomes containing granular materials of varying electron densities. Granular electron dense materials were also in endothelial cells and bile canaliculi. Fatty change, cholestasis, and rare piecemeal hepatic necrosis were minimal. The drug was primarily excreted through urine. Plasma concentration and half life of the drug were increased with multiple dosing. The highest concentration of unexcreted parent drug was in the liver. Drug-induced noninflammatory hepatic microgranulomatosis, apparently caused by sequestered drug-lipid/mucopolysaccharide complex in the phagocytic cells of the liver, can occur in any species, including humans, if orally administered xenobiotics are presented to the liver in particulate form.

Twenty-three biochemistry parameters and hematocrit were followed during 10 days in a 13 months old Arabian Oryx (Oryx leucoryx) during capture myopathy. An increase was found in bilirubin, creatine-kinase, alanine aminotransferase, and aspartate aminotransferase levels, but not in potassium level. Most of the parameters analyzed were the first given for this species.

Biochemical and metabolic indicators were monitored in a group of volunteers suffering from a variety of chronic illnesses participating in a week's course on a special uncooked vegetable diet, known as "living food". Unmatched healthy controls ate the same diet cooked for 2 min in a microwave oven. After 1 week on the regimen, serum protein and urea contents decreased and alanine aminotransferase (ALAT) activity increased in both groups, although all within the normal range. Blood glucose increased in both groups to slightly above normal limits but total serum cholesterol dropped about 1 mmol/l from normal starting levels. Serum tocopherol and retinol increased only in the group eating the uncooked diet. In both groups urinary sodium dropped drastically without a significant change in potassium. Serum and urinary phenol and p-cresol diminished also significantly. It is concluded that this vegetable diet may be of some benefit in the short term but any longer-term use requires evaluation.

Serum chemistry values were obtained from 64 adult San Joaquin kit foxes (Vulpes macrotis mutica) in western Kern County, California (USA). The goal of the study was to establish normal chemistry values for this endangered species. No significant differences were found for mean values of alanine aminotransferase (217.1 IU/l), alkaline phosphatase (44.2 IU/l), cholesterol (145.6 mg/dl), total protein (5.8 g/dl), creatinine (0.63 mg/dl), calcium (8.2 mg/dl), albumin (3.0 g/dl), glucose (129.2 mg/dl), amylase (196.8 IU/l), sodium (153.7 mEq/l) and phosphorus (5.42 mg/dl) between sexes or seasons. Significant differences were noted for aspartate aminotransferase, blood urea nitrogen and potassium between seasons. Possible disturbances in normal hepatic and renal functions were noted.

Monitoring of biochemical constituents in serum is an important component in revealing potential toxicity in humans and experimental animals due to exposure to a variety of xenobiotic agents. The relative toxicity of pure compounds, usually at large doses, has helped elucidate the mode of action of these compounds and their relative risk. However, most actual cases of environmental exposure present an extensive range of components and the potential for synergistic or inhibitory interactions. In this paper we review two such environmental cases: The Love Canal chemical dump site in Niagara Falls, NY, and the transformer fire at the State Office Building in Binghamton, NY. We focus on the clinical laboratory measurements obtained in these studies (including serum glucose, triglycerides, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyltransferase, lactate dehydrogenase, sodium and potassium), their usefulness, limitations, and application to such cases. Significant alterations in serum triglyceride and alanine aminotransferase levels were found in guinea pigs due to exposure to dioxins. These two tests were useful in estimating the 'equivalent' concentration of 2,3,7,8-tetrachlorodibenzo-p-dioxin in complex chemical mixtures.

Leakage of intracellular potassium and GPT in normal rat hepatocytes exposed to 10, 15 and 20 mmol/L of carbon tetrachloride (CCl4) in vitro was determined at 5, 10, 15 and 20 min after cell intoxication. Both of the intracellular potassium and GPT were clearly dose- and time-dependent with CCl4, but the leakage of intracellular potassium is a more sensitive index to indicate cell injury than the later. The percent change of intracellular potassium in regenerating rat hepatocytes 20 min after CCl4 (15 mmol/L) intoxication was markedly reduced than that in normal rat. This finding indicates that regenerating hepatocytes are resistant to CCl4 hepatotoxicity in vitro, and its mechanism presumably is due to a higher stability of regenerating liver cell membrane.
