In the RA-1000, a random-access discrete analyzer, an inert fluorocarbon fluid is used to prevent interaction and carryover. Production-model instruments were evaluated in two laboratories with respect to determination of glucose, creatinine, total protein, inorganic phosphorus, cholesterol, alkaline phosphatase, lactate dehydrogenase, creatine kinase, gamma-glutamyltransferase, and aspartate and alanine aminotransferases. Within-run, among-run, and day-to-day (for 15 days) precision was assessed, and results were correlated with those obtained by the methods routinely in use in our departments. Precision was excellent, correlation acceptable.

We determined normal reference values from data on sera of 2099 outpatient children (ages one week to 14 years) at our institution. Using a continuous-flow instrument (SMAC, Technicon), we determined the following analytes in each serum sample: glucose, creatinine, uric acid, inorganic phosphorus, sodium, potassium, chloride, total CO2, iron, cholesterol, triglycerides, total protein, albumin, total bilirubin, creatine kinase, lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, and calcium. The resulting data were coded and subsequently processed in an IBM 370 computer, and the reference values (3rd and 97th percentiles) were defined for each analyte. A two-way analysis of variance was also done to determine the influence of age and sex on results of these 20 biochemical tests.

Clinical and clinicopathologic features of transport tetany in 9 feedlot lambs were investigated. The lambs became recumbent within 10 days after arrival in the feedlot. The mean serum calcium concentration, mean magnesium concentration, and calcium:phosphorus ratio were significantly (P less than 0.01) less in affected lambs than in 6 unaffected lambs from the same feedlot. The mean serum phosphorus concentration was significantly (P less than 0.05) greater in the group of affected lambs. High activities of serum glutamic oxalacetic transaminase, creatine kinase, and lactate dehydrogenase in the serum of affected lambs indicated muscle necrosis, which was confirmed by histologic examination. Blood pH, HCO-3, and total carbon dioxide were significantly greater in affected lambs (P less than 0.01) than in unaffected lambs.

Postmortem chemical analysis of vitreous humor from Sudden Infant Death Syndrome (SIDS) infants was done. The results were compared to a pediatric control group. The concentrations of potassium, calcium, phosphorus, glutamic oxaloacetic transaminase, glutamic pyruvate transaminase, creatinine phosphokinase, and lactate dehydrogenase were all significantly different from the pediatric control group. Thus it appears that SIDS infants are a different population from the pediatric control group.

Turkey poults were fed diets containing oosporein at concentrations of 0, 500, 1,000, and 1,500 micrograms/g from hatching until three weeks of age. Low feed consumption resulted in poor growth rates at every dietary level of oosporein; however, a dose-related increase in water consumption was observed. The most significant effect of dietary oosporein was severe visceral and articular gout, with death ensuing in 24 and 52% of the poults at the 1,000 and 1,500 micrograms/g levels, respectively. Gout and mortality were absent at 0 and 500 micrograms/g. In addition to tissue urate deposition, necropsies revealed dehydration, swollen pale kidneys, hemorrhagic proventriculitis with mucosal necrosis, gizzard enlargement and lining discoloration, an increase in gall bladder size, and focal hepatic necrosis. The relative weights of the kidney, liver, proventriculus, gizzard, and pancreas were increased in a dose-related fashion; spleen and bursa weights were unaffected. Among plasma constituents, uric acid, urea, and the activities of glutamic-oxalacetic transaminase and lactic dehydrogenase were elevated in response to dietary oosporein; albumin, potassium, phosphorus, and calcium were decreased. The toxin had no effect on plasma total protein, sodium, glucose, cholesterol, triglycerides, alkaline phosphatase, or creatine phosphokinase. These data substantiate the original classification of oosporein as a nephrotoxin and etiologic agent of gout in avian species.

Venous blood values were determined on 19 Southdown sheep (9 adult ewes and 10 wether lambs). Principal sheep were given 12.5 ml of 3.3M urea solution/kg of body weight, which produced acute ammonia toxicosis. Whole blood ammonium-nitrogen was determined by ion exchange; venous blood gases and pH were measured with a pH blood gas analyzer; and 23 serum chemical analyses were obtained with a sequential multiple autoanalyzer computer. Analysis of variance for the data revealed significant changes for 20 values. The values are presented and discussed with regard to those that changed beyond acceptable limits (whole blood ammonium-nitrogen, venous blood pH, serum glucose, serum lactate dehydrogenase, serum alkaline phosphatase, serum creatine kinase, serum urea nitrogen, serum inorganic phosphorus, serum sodium, and serum potassium), those that changed within acceptable limits (PVo2, PVco2, serum triglycerides, serum free fatty acids, plasma volatile fatty acids, serum aspartate aminotransferase, serum total protein, serum albumin, serum creatinine, urea nitrogen-creatinine ratio, serum uric acid, serum cholesterol, serum low-density lipoproteins, serum calcium, serum iron and serum chloride), and those with no change (total and direct serum bilirubin and albumin-globulin ratio). Metabolic consequences of ammonia toxicosis are considered with regard to energy, lipid , protein, and acid-base and electrolyte balances. Blood values having possible laboratory diagnosis value and considerations for therapeutic adjustment are discussed.

The chemical measurements on our Technicon SMAC of lipemic sera before and after clearing lipemia by ultracentrifugation showed that uric acid, creatinine, carbon dioxide, calcium, phosphorus, potassium, and alkaline phosphatase were not affected significantly by lipemia, whereas sodium, urea, glucose, chloride and total protein showed small but significant increases with averages of less than 1.9 percent. Albumin showed a significant decrease of 1.2 percent. In contrast, the results for the enzymes, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) showed striking differences between pre- and post-centrifuged sera in a number of specimens. With lactate dehydrogenase, thirty-two of fifty specimens registered an increase in activity while with the aminotransferases, thirty-five and forty-one out of fifty specimens showed a decrease in aspartate aminotransferase and alanine aminotransferase activities, respectively. Although much of the lipemic interference can be explained by the volume displacement of serum by lipids or by interference by lipemia with colorimetry, the anomalous effects observed with the enzymes indicate the possibility of other, as yet, undetermined factor(s).

Monensin fed to beef cows at levels of 50, 200 or 300 mg daily during late gestation and early lactation induced feed savings of 3.2, 10.5 and 13.5%, respectively, when feed intakes were regulated to produce similar changes in cow weights, condition scores and weight to height ratios during the 168-day feeding period. Feed dry matter intakes were different (P < .05) for the orthogonal single degree of freedom comparisons that were made. The monensin treatments and the adjustments in feed intake associated with them had no apparent effect on (1) calf birth weights, (2) adjusted 205-day weaning weights or (3) first-service conception rates for the cows. Monensin increased (P < .05) the proportion of propionate and the ratio of acetate to propionate in rumen samples taken prepartum, but not in samples taken postpartum. Blood samples obtained at the same time that rumen samples were obtained showed no treatment effects on serum creatinine, lactic dehydrogenase, alkaline phosphatase, inorganic phosphorus, calcium, creatine phosphokinase, glutamic-pyruvic transaminase or total protein.

Fallow deer (Dama dama) were captured in an enclosure trap in southern New South Wales. Blood samples were collected for determination of haematological and biochemical values after capture and in one group after 3 h of transportation. Results were compared between fawns and does, transported and non-transported fawns, and transported and non-transported does. Fawns had higher haemoglobin, total red cell count, packed cell volume and lymphocyte numbers, but lower red cell indices and eosinophil numbers than does. Fawns also had lower levels of serum globulin than does, resulting in a higher albumin/globulin ratio in the former. The fawns had higher inorganic phosphorus, alkaline phosphatase and creatine kinase but lower glucose and urea nitrogen. There were only minor differences in red cell parameters and indices between transported deer but there were significant differences in the differential leucocyte counts, with the former having a relative neutrophilia with left shift, lymphopaenia and eosinopaenia. The effects of transport were also reflected in higher activities of the muscle enzymes aspartate aminotransferase, creatine kinase and lactate dehydrogenase. The non-transported deer had higher total white cell counts and higher lymphocyte and eosinophil counts than have been found previously in fallow deer.

The numerous physiological and nutritional factors which influence the concentration of serum calcium are considered. The causes of hypercalcaemia and hypocalcaemia are briefly discussed, with particular reference to the clinical symptoms and pathology. The effect of the acid-base status on the serum-ionized calcium level is stressed. The causes of changes in the serum concentrations of phosphorus and magnesium are briefly reviewed, along with the abnormalities of lactate, pyruvate, and hydrogen ion concentrations. The kidney function tests, blood urea nitrogen, serum creatinine, and the renal clearance tests are discussed, with emphasis placed on correlating their results with the findings from repeated urinalyses. The important physiologic influences and pathological processes which result in changes in the concentrations of these parameters are delineated. The causes of increases in the serum enzymes, alkaline phosphatase, alanine transaminase, asparate transaminase, lactic dehydrogenase, sorbitol dehydrogenase, glutamic dehydrogenase, gamma glutamyl transpeptidase, creatinine phosphokinase, amylase and lipase are discussed. The changes in serum bilirubin concentration and its components are fully described, with emphasis placed on the correlation of the findings with urinalysis data and the complexities resulting from the numerous pathologic conditions causing jaundice. These conditions are listed for each of the domestic animals. The other liver function tests, bromosulphthalein dye retention or excretion, serum uric acid and blood ammonia concentration are briefly considered. All the tests described are very useful, and frequently essential, in aiding the veterinary practitioner to arrive at a diagnosis and prognosis, but they never replace clinical acumen.
