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.

Several clinical chemical blood variables were compared, in order to evaluate the differences between Na heparinized plasma and serum samples. Samples from 45 healthy horses were used. No differences between the two sample substrates were found for aspartate aminotransferase, lactate dehydrogenase, lactate dehydrogenase-isoenzymes, creatine kinase, alkaline phosphatase, bilirubin, cholesterol, urea, total protein, alpha-globulin, gamma-globulin, albumin, calcium (Ca), phosphate (P), sodium (Na) and potassium (K). gamma-Glutamyltransferase and beta-globulin were significantly higher in heparinized plasma than in serum (each p less than 0.05) while magnesium (Mg) was lower (p less than 0.05). From the horse group used for the study, thoroughbreds in racing condition had significantly higher aspartate aminotransferase, gamma-glutamyltransferase, alkaline phosphatase, bilirubin, P and Mg as well as lower Ca and K values than riding horses, irrespective of the sample substrate used. It was concluded that expect for gamma-glutamyltransferase, beta-globulin and Mg, there was no significant difference between the clinical chemical variables of Na heparinized plasma and serum samples.

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)

These studies were designed to determine if macular mutant mouse, which is a proposed animal model of Menkes' kinky-hair disease, is sensitive to the acute toxic effect of Cu as compared to normal and heterozygote mice. Single sc injection of Cu were administered to 6- to 8-day-old mice, and mortalities were recorded for 30 days. The copper treatment at high doses (12 to 25 mg Cu/kg) was very toxic to mutant mice as compared to normal mice, and almost all mutant mice died within 10 days after injection. The effect of Cu toxicity on heterozygote mice was intermediate. The LD50 values 3 days after injection of Cu were 29.5 mg Cu/kg for normal mice, 23.5 mg Cu/kg for heterozygote mice, and 15.5 mg Cu/kg for mutant mice. In Cu-injected mutant mice (11 and 18 mg Cu/kg), significant elevations in serum aspartate aminotransferase and lactate dehydrogenase activity occurred as compared to Cu-injected normal and heterozygote mice. However, no significant elevations in serum creatinine and urea nitrogen contents in Cu-injected mutant were observed as compared to normal and heterozygote mouse. No significant differences in hepatic metallothionein(MT) and MT-1 mRNA, and serum ceruloplasmin oxidase activity levels were observed between Cu-injected normal and mutant mouse. These results indicated that macular mutant mice was sensitive to the acute toxic or hepatotoxic effects of Cu as compared to normal and heterozygote mice.

At sublethal concentrations, cypermethrin caused a decrease in total proteins and an increase in free amino acids, protease, alanine aminotransferase and aspartate aminotransferase in liver, brain and gill tissues of Tilapia mossambica. Nitrogen metabolic profiles like ammonia, urea and glutamine were also elevated in all the tissues as a consequence of cypermethrin toxicity. Glutamate dehydrogenase, AMP deaminase and adenosine deaminase activity was also increased in the present study.

To study the potential of multivariate classification methods in order to obtain more insight into abnormal laboratory data from patients with sickle cell disease, we investigated standard haematological and clinical chemical variables of 18 controls and 37 apparently healthy persons with heterozygous sickle cell disease (Hb AS), all women, using both univariate and multivariate classification methods. In the univariate method, those with Hb AS showed decreased serum log aspartate aminotransferase (log AST) activity, mean corpuscular volume and mean corpuscular haemoglobin (MCH) and increased sodium concentration. The multivariate method identified sodium, potassium, urea, uric acid, log AST, alanine aminotransferase and MCH as the variables that produced maximal separation between persons with Hb As and controls. It increased the 'non-error rate' for classification of persons with Hb AS by 16.4% compared with classification based on the variable, MCH, that produced maximal separation by the univariate method. The frequency distribution of percentage Hb S in the Hb AS group proved bimodal with maximal separation at 37.0% Hb S. The subgroup with 37.0% or less (n = 16) was considered to have concomitant heterozygous alpha-thalassaemia-2. In the univariate method the subgroup characterized by greater than 37.0% Hb S (n = 21) had increased serum sodium and uric acid concentrations, perhaps related to sickle cell nephropathy, whereas the subgroup with less than or equal to 37% Hb S did not. The multivariate method added information to the univariate method by additionally identifying abnormalities in serum potassium and urea concentrations in the former subgroup.(ABSTRACT TRUNCATED AT 250 WORDS)

Nineteen purebred Beagles of various ages (4, 5, 13, and 47 weeks) were inoculated with North American Trypanosoma cruzi isolates obtained from an opossum (Tc-O), an armadillo (Tc-A), or a dog (Tc-D). Dogs were grouped on the basis of clinical outcome of infection. During the acute stage of disease, dogs of group 1 (n = 7 inoculated with Tc-O or Tc-A) died or were euthanatized because of the severity of disease. Dogs of group 2 (n = 5 inoculated with Tc-O or Tc-A) developed acute disease, but survived to develop chronic disease. Dogs of group 3 (n = 7 Tc-D-inoculated dogs) developed neither acute nor chronic disease. Dogs of group 4 (n = 4--2 dogs 13 weeks old and 2 dogs 47 weeks old) served as noninoculated controls. Clinical signs associated with severe acute myocarditis developed in dogs of groups 1 and 2 between postinoculation day (PID) 15 and 28. Generalized lymphadenopathy and lymphocytosis were observed in all dogs of groups 1, 2, and 3 between PID 14 and 17. Serum alanine transaminase and aspartate transaminase activities and urea nitrogen concentration were high, and glucose concentration was low prior to death of dogs in group 1. Serum activities of isoenzymes of creatine kinase were significantly (P less than 0.05) high in only 1 dog (group 1), whereas serum lactate dehydrogenase isoenzyme activities were not significantly high in any dog.(ABSTRACT TRUNCATED AT 250 WORDS)

Abomasa from 912 randomly selected cows were examined; specimens were obtained at the local slaughter house on 35 days spread over one year. Abomasal lesions were assessed macroscopically and histologically. Additionally, haematological and blood chemistry (urea, aspartate aminotransferase, potassium, chloride, calcium) evaluations and the determination of rumen chloride concentration were performed. Of the 912 abomasa examined, 187 (20.5%) had ulcerative lesions of the mucosa. Lesions were classified from 1 to 4 based on severity as described by Whitlock (1980). All ulcers were classified as type 1 (erosions and non-perforating ulcers); thus, further division into four subtypes 1 a, 1 b, 1 c and 1 d was carried out. Fifty-six abomasa had minimal mucosal defects which were classified as type 1 a. Deeper erosions combined with local hemorrhage, classified as type 1 b, were observed in 54 abomasa. Type 1 c were crater-like ulcers and were seen in 61 abomasa. Sixteen abomasa had type 1 d ulcers which included two forms: ulcers with radial wrinkles converging on a central point, and ulcers with perforated folds. Types 1 a and 1 c occurred mainly in the pyloric region, and types 1 b and 1 d were observed mainly in the fundic region. Type 1 abomasal ulcus could not be diagnosed based on alterations in haematological or blood and rumen chemistry values.

Twenty-five transhepatic embolization procedures were carried out between 1984 and 1989 on 24 patients with life-threatening haemorrhage from gastric or oesophageal varices after conservative methods had failed. There were two deaths related to the procedure and another 17 patients died during the following year. There were five survivors at 1 year, four are alive and well 4 years later, the fifth was lost to follow-up at 2 1/2 years. Survival at 1 year was not affected by a number of factors present at the time of embolization including the underlying liver pathology, the patient's age, platelet count, blood urea, serum bilirubin or the embolization technique. However, survival at 1 year was related to more normal coagulation values (international normalized ratios, INR) P less than 0.005, normal serum aspartate aminotransferase levels (P less than 0.025) and Pugh's grade A (P less than 0.01). We conclude that this procedure can prolong the survival of a small proportion of good risk patients.

Changes in the protein metabolism of gill, kidney and intestine of freshwater fish, Cyprinus carpio exposed to 1, 15 and 30 days to sublethal concentration (0.1 mg/l) of mercury were studied. The total, soluble and structural protein contents recorded the depletion followed by progressive increase in accumulation of free aminoacids. Concurrently, the activity of protease in the tissues was also increased. A steady enhancement in the activities of aspartate aminotransferase and alanine aminotransferase paralleled the elevation of glutamate dehydrogenase activity in the organs studied. Levels of ammonia and urea have also reported elevation. All these changes clearly documented the induction of severe proteolysis. The magnitude of these changes increased overtime. These changes were more in the gill at the initial periods of exposure (1 and 15 days), but as the period of exposure increased, these changes were more pronounced in the kidney at 30 days of exposure to sublethal concentration of mercury.
