Effects of administration of triflupromazine were evaluated in 11 adult domesticated camels (Camelus dromedarius) weighing 403 +/- 29.5 kg (Mean +/- SE). Six camels were used to evaluate sedative properties of the drug and its effects on haematological and blood biochemical parameters. In the remaining 5 camels, effects on haemodynamics, acid base status and blood gases were studied. In all the animals triflupromazine was administered intramuscularly in the gluteal region at the rate of 2 mg/kg. Camels voluntarily sat down 48.9 +/- 5.4 min after administration of the drug but stood up again if disturbed. Drowsiness, drooping of lower lip and salivation were evident. The animals stood on their own and started walking with ataxia after 159 +/- 7 min and recovered completely from the effect of drug within 259 +/- 23 min. The drug caused a significant tachycardia and a moderate hypotension. The decrease in central venous pressure was also significant. Rectal temperature, respiratory rate, acid base status, blood gases, haemoglobin concentration, packed cell volume, total erythrocyte count, total leucocyte count, differential leukocyte count, blood urea nitrogen, plasma alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, alkaline phosphatase, blood glucose and plasma concentrations of sodium, potassium, chloride and inorganic phosphate were not significantly affected by triflupromazine.

Blood and milk samples were taken at first insemination in 352 dairy cows from 18 herds for charting the relation between clinico-chemical parameters and fertility rate. Neither total protein, albumin, globulin, AST, bilirubin, bile acids, calcium, magnesium and phosphorus in blood nor urea in milk was significantly related to the rate of pregnancy. On the other hand, there was a significant difference for plasma glucose between cows that became pregnant and those that did not. Cows with low plasma glucose concentrations at first insemination also had low values four and seven weeks after calving, indicating that it is primarily cows with chronically low blood glucose which are likely to have reduced fertility. At first insemination there was no increase in the concentration of acetone in milk of cows with reduced fertility. However, they had had increased milk acetone concentrations three to five weeks after calving. It therefore seems possible to evaluate the risk of reduced fertility by measuring either blood glucose or milk acetone some weeks after calving. Owing to the difficulties associated with the sampling and laboratory techniques for glucose, analyses of milk acetone are more suitable under field conditions.

Milk production of dairy cows in six herds was increased by approximately 15% by the administration of recombinantly derived bST in a sustained-release vehicle (somidobove, Eli Lilly/Elanco, Indianapolis, IN) at 28-d intervals, which commenced at 52 to 104 d postpartum. Milk composition, acidity, flavor, and growth of commercial lactic acid starter cultures were unaffected by somidobove treatment. No adverse effect upon health (metabolic diseases, mastitis) and reproduction was noted. Blood glucose, FFA, aspartate aminotransferase, alanine aminotransferase, Ca, Na, and K were unaffected by the application of somidobove. Somidobove did not affect the appearance of the organs of cows at slaughter; however, somidobove-treated cows had less subcutaneous and omental adipose tissue than controls. Cultured explants of subcutaneous adipose tissue of treated cows showed significantly lower lipogenesis from acetate than controls. The release of FFA was not affected by treatment. Recombinantly derived somidobove has been judged in Czechoslovakia to be effective and safe for cows and the environment. Edible products from the treated cows are safe for human consumption.

The rapid weight decrease at the beginning of strict slimming regimens leads often to an inconsiderate shortening of these cures. Our long-term experience with a slimming regimen lasting 13 days based on diet (3.7 MJ) and 4 hours of supervised exercise of low to moderate intensity was omitted by the organizers. They shortened the cure to 8 days. We checked therefore a group of obese women on the first, eight and twelfth day in the course of this regimen. A statistically significant decrease of serum insulin, growth hormone, triiodothyronine and cholesterol was observed on the twelfth day. These trends were not significant on the eighth day. On the other hand, the step-test revealed on the eighth day a reduction of the heart rate during recovery. Nevertheless, a higher level of significance was obtained after 12 days. No significant response to the regimen was obtained in the case of blood glucose, thyroxine, cortisol, uric acid, AST and ALT. The advantages of the 12-day regimen are discussed--especially the decrease of insulinemia, because hyperinsulinemia is responsible for several complications of obesity. The importance of the decrease of cholesterolaemia and the modification of heart rate after a load was also stressed. These favourable effects are not depreciated by a smaller weight loss in the second week due to an enhanced protein synthesis, stimulated by exercise and supported by a decrease of T3 which protects the organism against energy deficit.

In this study we have investigated the effects of hepatocytes glycogen storage on the quality of livers for transplantation. Rats were fed or fasted for 24 h and hepatocytes isolated and cold stored in UW solution for 24 and 48 hours. Viability of the cells was analyzed by LDH release after 2 hours incubation in L15 with O2. Also, rabbits were fed, fasted (48 h) or glucose fed (48 h) and livers cold stored for 6, 24 and 48 h in UW solution. Functions of the livers were analyzed by isolated perfusion for 2 hours. Hepatocytes from fasted rats released significantly more LDH than hepatocytes from fed rats after 24 and 48 h cold storage. In rabbit livers, fasting depleted glycogen by 85% but had no effect on ATP or glutathione concentration. Livers from fasted rabbits produced similar amount of bile, released similar concentrations of lactate dehydrogenase and aspartate transaminase into the perfusate, maintained similar concentrations of glutathione after 24 hours preservation when compared to fed animals. After 48 h preservation livers from fasted animals were less viable than livers from fed animals and the decrease of liver functions in livers from fasted animals preserved for 48 hours was prevented by feeding glucose. This study shows that liver glycogen storage in hepatocyte is an important metabolite for successful liver preservation. Glycogen may be a source for ATP and antioxydant synthesis during the early period of reperfusion.

Since the occurrence of rhabdomyolysis may elevate the serum concentration of potassium, hypokalemia as a cause of rhabdomyolysis often goes unrecognized in many instances. We undertook this study to evaluate the occurrence and determinants of rhabdomyolysis in the hypokalemic state. To identify patients with a hypokalemic state, we reviewed medical admissions for the period January 1988 through December 1989. A total of 120 patients (42 men and 78 women) were included in the present study. Thirty-eight hypokalemic patients showed biochemical evidence of rhabdomyolysis (serum creatine phosphokinase greater than 244 IU/l). The clinical and biochemical characteristics of the patients with rhabdomyolysis (group I) and the hypokalemic patients without rhabdomyolysis (82 patients, group II) were compared. There was no difference in age, sex and race of the patients of group I vs. group II. The mean serum values for potassium, bicarbonate, chloride, blood urea nitrogen, glucose, lactate dehydrogenase and uric acid were also not different between the two groups. The mean serum osmolality was higher (p less than 0.001) in patients with rhabdomyolysis (297.6 +/- 4.3 mosm/kg) than in those without rhabdomyolysis (283.5 +/- 5.0 mosm/kg). The levels of serum glutamic-oxaloacetic transaminase were elevated (p less than 0.001) in group-I patients (69.6 +/- 8.4 IU/l) but not in group-II patients (36.7 +/- 3.5 IU/l). The concentrations of serum creatinine were also higher (p less than 0.05) in patients with rhabdomyolysis (1.4 +/- 0.2 mg/dl) than in those without rhabdomyolysis (1.0 +/- 0.1 mg/dl). The mean values for serum sodium were higher (p less than 0.02) in group-I patients when compared to group-II patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Hydrated sodium calcium aluminosilicate (HSCAS), an anticaking agent for mixed feed, was added to the diets of growing wethers (mean body weight, 34.0 kg) and was evaluated for its ability to diminish the clinical signs of aflatoxicosis. The experimental design consisted of 4 treatment groups of 5 wethers each, consuming concentrations of 0 g of HSCAS and 0 g of aflatoxin (AF)/kg of feed (control; group 1); 20 g of HSCAS/kg (2.0%; group 2), 2.6 mg of AF/kg (group 3); or 20 g of HSCAS (2.0%) plus 2.6 mg of AF/kg (group 4). Wethers were maintained in indoor pens, with feed and water available ad libitum for 42 days. Lambs were observed twice daily and weighed weekly, and blood samples were obtained every 2 weeks for hematologic and serum biochemical analyses and for measurement of mitogen-induced lymphocyte-stimulation index. At the termination of the study, wethers were euthanatized and necropsied. Body weight gain was diminished significantly (P less than 0.05) by consumption of 2.6 mg of AF/kg of feed, whereas body weight of lambs consuming HSCAS plus AF did not differ from that of control wethers. The AF-alone treatment increased serum aspartate transaminase and gamma-glutamyltransferase activities, prothrombin time, and cholesterol, uric acid, and triglyceride values and decreased albumin, glucose, and urea nitrogen values, and urea-to-creatine ratio.(ABSTRACT TRUNCATED AT 250 WORDS)

Plasma components of 6 to 12-month-old beagles were examined using a Technicon auto-analyzer. Age-related changes were noted for 8 of the 21 components: the levels of total protein (T. Pro) and iron (Fe) gradually increased while those of alkaline phosphatase (ALP), creatine phosphokinase (CPK) and inorganic phosphorus (Pi) persistently decreased in both sexes. Triglyceride (Trigly) in female dogs, glutamic-pyruvic transaminase (GPT) and urea nitrogen (Urea-N) in male dogs tended to increase. The following thirteen components showed no significant variation during the period of observation: glucose (Glu), lactic dehydrogenase (LDH), albumin (Alb), creatinine (Crea), glutamic-oxaloacetic transaminase (GOT), leucine aminopeptidase (LAP), total bilirubin (T. Bil), amylase (Amy), total cholesterol (T. Chol), sodium (Na), potassium (K), chloride (Cl) and calcium (Ca). Our results generally agree with the reported findings on beagles from various institutions.

The laboratory contribution in the care of a seriously ill child is essential to plan and organize the therapy after the first-step emergency care and to know the aethiology of the illness. The most acute syndromes in pediatric emergency care are: coma, convulsions, dehydration, metabolic disequilibrium, hypovolemic or anaphylactic shock, serious infectious diseases and chemical or drug poisoning. The laboratory tests which have to be available within few minutes are blood cell count, hemogasanalysis, sodium, potassium and calcium, glucose. Total proteins, serum creatinine and urea, bleeding tests, blood smear, sedimentation rate, ALT, AST, osmolality, urinary electrolytes and creatinine and cerebrospinal fluid examination should be available within sixty minutes. New accurate and rapid techniques and instrumentations make easier the diagnostic and therapeutical approach to pediatric emergency.

We reviewed the results of preoperative screening laboratory tests in asymptomatic healthy patients who underwent elective surgical procedures at our institution in 1988. Substantially abnormal results were found in 160 of 3,782 patients. All such abnormalities involved five tests: aspartate aminotransferase, glucose, potassium, platelet count, and hemoglobin. Thirty of the abnormal test results were predictable on the basis of the history or physical examination. The abnormal test result prompted further assessment in 47 patients. No surgical procedure was delayed, and no association was noted between adverse outcome and any preoperative laboratory abnormality. Because of our findings in this analysis and similar studies on specific tests from other institutions, we no longer require preoperative laboratory screening tests for healthy patients.
