The effectiveness of levamisole hydrochloride as a microfilaricidal agent when used 3 weeks after thiacetarsamide sodium therapy for canine dirofilariasis, was studied in 6 experimental dogs and 20 clinical cases. The drug, when administered orally in gelatine capsules daily, cleared microfilariae from the circulation in the experimental dogs in 7 to 11 days. A dose rate of 10mg/kg appeared as effective as 15mg/kg. In the clinical group 70% of dogs had zero microfilarial counts after 4 to 8 doses at 10mg/kg daily. Vomiting, diarrhoea and inappetence were observed in some animals, but were not a significant problem. Elevations in plasma GPT and AP levels were recorded during the administration of levamisole in some dogs while GOT levels rose in 1 dog only. Urea and creatinine levels were unaffected in all dogs. The only haematological parameter affected was the eosinophil count which rose during levamisole administration. All levamisole-treated animals, were successfully commenced on daily DEC, as a prophylactic measure, while an anaphylactic-type reaction occurred when this drug was administered to 1 of the 2 control animals.

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.

Blood samples were collected from 91 rusa deer (Cervus timorensis russa), immediately after being shot. Serum mean biochemical values from shot deer are presented for blood urea nitrogen, creatinine, creatine kinase, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin, total protein, albumin, calcium, and phosphorus. Mean total protein and albumin increased with age. There was an age-associated increase of gamma globulins. Mean creatine kinase activity and creatinine, albumin and phosphorus concentrations were higher in stags than in hinds. Pregnant hinds had lower mean creatine kinase activity and phosphorus and higher mean alanine aminotransferase and total protein than non-pregnant hinds. Mean calcium concentration increased when deer were agitated before bleeding.

The critical difference, which may help to judge whether the difference between two consecutive analytical results may be safely ascribed to natural variation or not, was calculated for 12 clinical chemical components determined in blood samples collected once a week for 5 consecutive weeks from 19 clinically healthy Red Danish dairy cows. For each clinical chemical component, the total variance of the analytical results was divided into the component of variance between cows (S2Inter), the component of variance for weeks within cows (S2Intra) and the component of variance for measurements (S2Anal) using nested analysis of variance. The critical difference calculated in absolute values from S2Intra and S2Anal was 0.15 mu kat per 1 for alanine aminotransferase, 0.55 mu kat per 1 for aspartate aminotransferase, 0.57 mu kat per 1 for alkaline phosphatase, 0.14 mu kat per 1 for gamma-glutamyltransferase, 1.95 mu kat per 1 for creatine kinase, 2.23 mmol per 1 for urea, 22 mu mol per 1 for creatinine, 2.4 g per 1 for albumin, 10.0 g per 1 for serum protein Total, 0.71 mmol per 1 for glucose, 0.54 mmol per 1 for calcium and 0.25 mmol per 1 for magnesium. These critical differences may be used as guidelines to evaluate the difference between two consecutive analytical results in cows. However, the analytical results should not be assessed by the critical differences alone, but should also be compared with the corresponding reference intervals.

Fifteen Slovak Merino sheep were included in the experiment. The animals weighing 21-28 kg were divided into three groups per five animals. In a six-week feeding experiment the animals of group I were given 50 mg supermethrin per kg live weight per day while those of group II received 200, and from week four of the experiment 300 mg supermethrin per kg live weight per day. During the experiment changes of aspartate aminotransferase (EC 2.6.1.1), alanine aminotransferase (EC 2.6.1.2), acetylcholine esterase (EC 3.1.1.7), urea und creatinine levels in blood serum were observed. Six weeks after supermethrin treatment the sheep were slaughtered and histochemical evaluation of alkaline phosphatase (EC 3.1.3.2), acid phosphatase (EC 3.1.3.1) and non-specific esterase (EC 3.1.1.1) was carried out in liver, kidney, duodenum, jejunum and ileum. In the course of the experiment changes of the enzymatic activities of aspartate aminotransferase observed in both experimental groups of sheep were similar to those seen in the control group of animals (Tab. I). As compared to the starting values, no significant changes in the activity of alanine aminotransferase were observed in group II of the experiment and in the controls. However, a significantly decreased alanine aminotransferase activity could be seen in the blood serum of sheep of group I (Tab. II). In both experimental groups of animals no significant changes in the acetylcholine esterase could be seen (Tab. III). As compared to the starting values, no significant changes were observed in creatinine levels of the control and the 1st experimental group of sheep (Tab. IV). In the sheep of the 2nd group a temporary significant decrease (p < 0.05) in creatinine levels was seen. The dynamics of urea levels was similar to starting values in all animals throughout the experiment Tab. V). In the control group of animals (Fig. 1) the high density of reaction product of alkaline phosphatase was determined in the microvilli of enterocytes of the small intestine. In the small intestine of the animals of both experimental groups, the activity of this enzyme was shown to be located in the same zone (Fig. 2). In all experimental animals in the parenchyma of the liver and kidney no significant changes could be observed. In both experimental and control animals the high activity of acid phosphatase was demonstrated to be located especially in the cytoplasma of enterocytes. The activity of non-specific esterase was located in the cytoplasma of enterocytes of the small intestine, in the intestinal crypts its activity was slight up to high.(ABSTRACT TRUNCATED AT 400 WORDS)

Simian hemorrhagic fever (SHF) virus and a new strain of Ebola virus were isolated concurrently in recently imported cynomolgus monkeys (Macaca fascicularis) being maintained in a quarantine facility. Ebola virus had never been isolated in the U.S. previously and was presumed to be highly pathogenic for humans. A chronology of events including measures taken to address the public health concerns is presented. The clinicopathologic features of the disease were abrupt anorexia, splenomegaly, marked elevations of lactate dehydrogenase, alanine aminotransferase, and aspartate aminotransferase, with less prominent elevations of blood urea nitrogen, creatinine, and other serum chemistry parameters. Histologically, fibrin deposition, hemorrhage, and necrosis of lymphoid cells and reticular mononuclear phagocytes were present in the spleens of SHF and of Ebola virus-infected animals. Intravascular fibrin thrombi and hemorrhage were also present in the renal medulla and multifocally in the gastrointestinal tract. Necrosis of lymphoid and epithelial cells was occasionally noted in the gastrointestinal tract. The histopathologic findings considered specific for Ebola virus infection include hepatocellular necrosis, necrosis of the zona glomerulosa of the adrenal cortex, and interstitial pneumonia, all of which were generally associated with the presence of 1 to 4 mu intracytoplasmic amphophilic inclusion bodies. The disease spread within rooms despite discontinuation of all direct contact with animals, and droplet or aerosol transmission was suspected. Antibody to Ebola virus developed in animal handlers but no clinical disease was noted, suggesting a less virulent strain of virus.(ABSTRACT TRUNCATED AT 250 WORDS)

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)

Twenty-six 3-week-old genetically obese pigs were fed in two experiments to determine the serum chemistry profile during severe protein malnutrition and repletion. Severe protein deficiency was produced in pigs fed the high-fat, low-protein diet (growth failure, rough hair, low serum total protein and albumin). In Experiment 1, blood was sampled from the anterior vena cava of each pig five times during depletion and three times during repletion to determine serum total cholesterol, high density lipoprotein (HDL)-cholesterol, triglycerides, total protein, albumin, glucose, Ca, inorganic P, Mg, Na, K, Cl, total bilirubin, urea N, creatinine, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyltransferase. In Experiment 2, blood was sampled weekly for 8 weeks for serum total cholesterol, HDL-cholesterol, triglycerides, albumin, glucose, Ca, P, Mg and alkaline phosphatase. HDL-cholesterol was increased (P less than 0.01) and albumin was decreased (P less than 0.01) in protein-deficient pigs in both experiments. Creatinine, total bilirubin, gamma-glutamyltransferase, alanine aminotransferase, and aspartate aminotransferase were elevated in protein-deficient pigs compared with controls after 7 weeks of depletion. Inorganic P (P less than 0.01), Ca (P less than 0.01), and Mg (P less than 0.05) concentrations were depressed in protein-depleted pigs compared with controls in both experiments. After 8 weeks of repletion in Experiment 1, all elements except inorganic P were similar in the two groups. Short-term, severe, protein malnutrition affected lipid, electrolyte, and structural mineral metabolism and indices of liver function in the absence of parasites, diarrhea, and infection. The effects were reversed after 8 weeks of repletion. We conclude that the elevated serum cholesterol in protein deficiency is related primarily to an increase in the HDL fraction.

A subacute toxicity study of pentavalent antimony (Sb) compounds, sodium stibogluconate (SSG) and meglumine antimoniate (MA) was carried out in rats. Three groups of 10 rats each were treated with saline (control group), 300 mg Sb kg-1 d-1 or 900 mg Sb kg-1 d-1 of SSG for 30 d. A parallel study of similar type was conducted for MA. Compared with controls, drug-treated rats showed an impairment of feeding habits and retardation of weight gain (P less than 0.01) during the treatment period. In both SSG- and MA-treated rats there was a dose-related reduction in haemoglobin concentration (P less than 0.001), and hematocrit (P less than 0.001). Red cell count was reduced in SSG-treated rats only. Both drugs, however, significantly raised the white cell count (P less than 0.05). These changes were more pronounced with SSG them with MA. There was no change in MCV, MCH and MCHC. SSG, 900 mg Sb kg-1 d-1, significantly raised AST (P less than 0.005), ALT (P less than 0.01) and alkaline phosphatase activity (P less than 0.01). SSG-treated rats also had raised BUN (P less than 0.01) and creatinine (P less than 0.001), but no significant change in bilirubin levels. MA significantly raised AST (P less than 0.01), ALT (P less than 0.01), BUN (P less than 0.001) and serum creatinine levels (P less than 0.001), but had no appreciable effect on bilirubin and alkaline phosphatase levels. Both SSG and MA decreased blood glucose levels (P less than 0.01) and induced proteinuria.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of selenite coadministration on the toxicity and antitumor activity of repeated treatment with high doses of cis-diamminedichloroplatinum (cis-DDP) was examined in mice. Sodium selenite was injected s.c. into separate abdominal sites of mice together with cis-DDP at a molar ratio of 1:3.5 (selenite to cis-DDP) on day 0. The same amount of selenite was given daily for 4 subsequent days (days 1-4). This fixed administration schedule was repeated weekly for a total of 7 weeks. Under the experimental conditions used, the lethal toxicity, renal toxicity [indicated by an increase in blood urea nitrogen (BUN) and plasma creatinine levels], hepatic toxicity (indicated by an increase in plasma GPT and GOT activity), and myelotoxicity (indicated by a decrease in the numbers of leukocytes and platelets) observed in mice given repeated doses of cis-DDP alone (15 or 25 mumol/kg, s.c.) were significantly depressed by the coadministration of sodium selenite. Treatment with cis-DDP alone (15, 20, or 25 mumol/kg, s.c.) resulted in some dose-dependent prolongation of the life span of mice transplanted either s.c. with colon adenocarcinoma 38 (colon 38) or i.p. with P388 leukemia (P388) but did not completely depress the tumor growth, and the animals died of either progressive disease or cis-DDP-induced toxicity. However, following the coadministration of 7.1 mumol/kg selenite with 25 mumol/kg cis-DDP, all of the mice transplanted either s.c. with colon 38 or i.p. with P388 survived for as long as 4 months after the end of the treatment and showed no evidence of malignancy. These results indicate that selenite coadministration enables the use of increasing doses of cis-DDP and, consequently, enhances the antitumor effect of cis-DDP by depressing its side effects.
