The effects of three widely spaced levels of bacterial contamination of reagent water on several chemistry, radioimmunoassay, and coagulation procedures were studied. These included determinations of lactate dehydrogenase, creatine kinase, aspartate transaminase, alkaline phosphatase, blood urea nitrogen, total protein, thyroid-stimulating hormone, digoxin, thrombin time, activated partial thromboplastin time, and prothrombin time. Statistical analyses included calculations of means and coefficients of variation, and analysis of variance, as well as correlation coefficients for test results versus logarithm of bacterial contamination. Statistically and clinically significant differences occurred together only for an elevated level of creatine kinase.

Normal values for 13 chemical constituents of plasma were estimated from results for 837 presumably healthy children. Ninety microliters of specimen was analyzed for lactate dehydrogenase, aspartate aminotransferase, alkaline phosphatase, inorganic phosphorus, total calcium, total cholesterol, total proteins, albumin, uric acid, urea nitrogen, alanine aminotransferase, total bilirubin, and glucose. We used two Abbott ABA-100 Bichromatic Analyzers interfaced directly to the ABA Data Management System. For each test age- and sex-related variations were assessed and normal values were estimated for six different age groups.

In order to verify the influence of sampling time on blood constituents, populations of supposedly healthy subjects were grouped according to age, sex, deviation from their ideal weight, state of fasting or nonfasting, and time of sampling. Each fasting subject in one group underwent two samplings during the course of a morning: the first at 08.00 and the second between 09.00 and 12.00. In the second group, the first was taken at 13.00, and the second between 14.00 and 16.00. Subjects in the second group had eaten a standard meal of 700 calories at 12.00. Differences between the paired samples from a given individual are discussed with respect to the time of sampling for plasma urea, creatinine, proteins, albumin, calcium, sodium, potassium, cholesterol, uric acid, chloride ions, phosphate, bilirubin, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, creatine phosphokinase, alkaline phosphatase, hemoglobin and erythrocyte and leukocyte counts. Variations due to the time of sampling were large for phosphorus, bilirubin, and leukocyte count.

The Olympus "Quickrate", a photometer built for both kinetic and end point analysis was evaluated in this laboratory. Aspartate transaminase, lactate dehydrogenase, hydroxybutyrate dehydrogenase, creatine kinase, alkaline phosphatase and gamma glutamyl transpeptidase were measured in the kinetic mode and glucose, urea, total protein, albumin, bilirubin, calcium and iron in the end point mode. Overall, good correlation was observed with routine methodologies and the precision of the methods was acceptable. An electrical evaluation was also performed. In our hands, the instrument proved to be simple to use and gave no trouble. It should prove useful for paediatric and emergency work, and as a back up for other analysers.

The intermethod analytical variability of 59 commercially available control sera was compared with that of patient sera. For this purpose, patient and control sera were assayed with respect to ten constituents (albumin, alkaline phosphatase, alpha-amylase, cholesterol, glucose, iron, lactate dehydrogenase, creatinine, protein, and urea), each with two analytical methods. Only 6 of the 59 control materials showed an intermethod analytical variability comparable to that of the patient sera for all of the determinations. The use of patient sera for the calibration of routine analytical methods is recommended.

Hematological and biochemical parameters in five Thoroughbred foals during the first six months of life are reported. The samples were analyzed for red blood cell, packed cell volume, hemoglobin, platelet, white blood cell, absolute number for leukocytes, and erythrocyte fragility and serum calcium, inorganic phosphorus, sodium, potassium, chloride, magnesium, alkaline phosphatase, icterus index unit, bilirubin, blood urea nitrogen, nonprotein nitrogen, blood glucose, lacticdehydrogenase, glutamic pyruvic transaminase, glutamic oxalacetic transaminase, total protein, albumin, globulin, and A/G. The changes of these parameters are presented in relation to age after birth.

The effect of cadmium (1, 10, or 100 ppm) administered to male rats in drinking water for 13 weeks on body weight and mineral disposition (Cd, Mg, P and Zn) in several body tissues was examined. Most alterations observed in these parameters occurred only at the 100 ppm dose of Cd. Terminal body weight was decreased by 10% in rats ingesting Cd at 100 ppm resulting from decreased food intake since weight gain/food consumption ratio was the same for all treatment groups. In serum, cadmium ingestion resulted in an inhibition of alkaline phosphatase activity at all concentrations and phosphorous was elevated only in animals receiving 100 ppm Cd. No changes were observed in Ca in urea. In bone, Cd decreased zinc content, increased Ca content, but did not influence bone ash, Mg or P and roentgenographic examination revealed no bone abnormalities. In both liver and kidney, cadmium ingestion did not influence intestinal absorption of Ca, Mg, P, or Zn or the renal excretion of Ca, P, or urea. The results of this study indicate that alterations in body weight and tissue mineral disposition resulting from chronic Cd ingestion are dose-related.

Isatin has been found to inhibit rat testicular alkaline phosphatase (EC 3.1.3.1) uncompetitively. The hyperbolic curve relating inhibition as a function of substrate concentration; the persistence of inhibition after the tertiary structure of the enzyme has been altered by heat denaturation, exposure to urea or papain digestion; the small changes in entropy, free energy and enthalpy in the presence of isatin, and the number of isatin molecules (n = 1.29) combining with one molecule of enzyme indicate the non-allosteric nature of inhibition.

Eight weeks following pinealectomy in adult male Wistar rats, zinc levels of various tissues were found to be significantly altered: zinc in thoracic aorta was significantly increased, and in serum, pituitary, adrenal, heart, lung, and body hair, it was decreased. Serum biochemical analysis indicated that there was a significant elevation of cholesterol, alkaline phosphatase, sodium, urea, and creatinine in serum from pinealectomised rats. Liver, spleen, and thymus weights were lower following pinealectomy, although hearts were increased. The effects of pinealectomy on zinc levels in serum and tissues and on serum cholesterol and alkaline phosphatase may be related to its effects on vascular reactivity and liver fibrosis.

Alkaline-phosphatase activity and the physico-chemical properties of the liver, lung, spleen, kidney, intestine, bone and placenta of 25 clinically healthy cattle and 30 clinically healthy sheep were investigated. High alkaline phosphatase activity was detected in kidneys and intestines. The alcaline phosphatase of cattle and sheep liver, spleen, kidney, lung, bone and placenta was thermo-labile and sensitive to l-arginine, l-homoarginine and imidazole, but was not sensitive to l-phenylalanine. Bone phosphatase of cattle and sheep was sensitive to urea. Intestinal phosphatase of cattle proved thermostable, sensitive to l-phenylalanine and not sensitive to l-arginine, l-homoarginine, imidasol and urea. Agarose gel electrophoresis of alkaline phosphatase indicated the presence of one fraction only and liver alkaline phosphatase proved to be the fastest. Sheep liver alkaline phosphatase had two fractions while sheep intestinal and placental alkaline phosphatase had three fractions and some of them were faster than liver alkaline phosphatase.
