A Pacific white-sided dolphin (Lagenorhynchus obliquidens) developed clinical signs, serum biochemical values, and serologic viral markers consistent with chronic persistent hepatitis caused by a hepatitis B-like virus. The hepatitis had a sporadic cyclical pattern of lethargy, inappetance, and icterus, with leukocytosis and increased serum activities of alanine transaminase, aspartate transaminase, and gamma-glutamyltransferase. The serum from this dolphin contained hepatitis B virus core antibodies, hepatitis B surface antibodies, and hepatitis B viral DNA. Supportive treatment consisted of administration of antibiotics, cimetidine, menadiol sodium diphosphate, and vitamin/dextrose supplementation. A clinically normal killer whale (Orcinus orca) housed in the same pool had serum hepatitis B surface antibodies, suggesting immunologic responsiveness and that this disease was not species-specific.

Portosystemic shunt was diagnosed in a 6-month-old Quarter Horse filly with acute onset of apparent blindness and a 3-month history of depression, lethargy, and ataxia. Clinicopathologic test results indicated slightly high gamma-glutamyl transpeptidase activity and serum total bilirubin concentration. Sulfobromophthalein half time was prolonged, and plasma ammonia and serum bile acid concentrations were high as well. Histopathologic findings of percutaneous liver biopsy included widespread hepatocyte atrophy and numerous prominent small arterioles in the area of the portal triad. On the basis of history, clinical findings, and clinicopathologic abnormalities, a presumptive diagnosis of portosystemic vascular anomaly was made. To confirm the tentative diagnosis, nuclear hepatic scintigraphy and operative mesenteric portography were performed. Medical treatment was unsuccessful, and the foal was euthanatized. Portosystemic shunts have been described in dogs and cats, but few cases have been reported in large animal species. Other, more common causes of neurologic abnormalities in foals, such as trauma, vertebral body abscesses, brain abscesses, and meningitis, must be ruled out before portosystemic shunt is considered.

1. At 30 weeks of age, homozygote diabetic C57 BL KsJ (db/db) mice were grossly obese, lethargic and displayed moderate hair loss relative to heterozygote control C 57 BL KsJ (db/+) mice. 2. In diabetic mice, compared to control, the total body weights, liver weight: body weight ratios, and blood glucose levels were increased 2.3 fold, 20% and 3.1 fold, respectively. 3. Analysis of plasma membranes isolated from control and diabetic mouse liver established that comparable purity levels were achieved since relative specific activities of the plasma membrane markers 5'-nucleotidase and gamma-glutamyltranspeptidase were similar: 10.2 and 11.4 fold with respect to 5'-nucleotidase in control and diabetic states respectively; and 8.0 and 8.3 fold with respect to gamma-glutamyltranspeptidase in control and diabetic states respectively. 4. A select effect of diabetes on gamma-glutamyltranspepetidase, however, was observed. The activity of this enzyme was found to be reduced 16% in diabetic liver compared to control liver. 5. Assessment of [3H]prazosin and [3H]dihydrolalprenolol binding to mouse liver plasma membranes indicated that although there was no difference in beta-adrenergic receptor binding in control and diabetic states, alpha 1-adrenergic receptor binding was found to be reduced 43% in diabetic mouse liver plasma membranes. 6. Scatchard analyses of kinetic studies indicate that the reduction is a reflection of decreases in alpha 1-adrenergic receptor numbers with no change in alpha 1 receptor affinity in the diabetic state: since for diabetic and control liver plasma membranes, Kd values were 3.41 +/- 0.02 nM and 3.40 +/- 0.01 nM respectively; and Bmax were 650.12 +/- 16.44 fmol mg-1 and 380.76 +/- 12.92 fmol mg-1, respectively.

Seven horses developed clinical or subclinical hepatitis 48 to 87 days after administration of tetanus antitoxin. One horse had mildly high hepatic enzyme activity 120 days after inoculation with tetanus antitoxin. The first horse developed signs of depression, lethargy, and anorexia. During hospitalization, signs of hepatoencephalopathy were noticed, and laboratory data were consistent with hepatic disease. Another horse that was found dead had gross and histologic lesions compatible with serum hepatitis. Screening of serum gamma-glutamyltransferase (GGT) and aspartate transaminase activities were used to investigate the remaining horses in the herd. High GGT activities (71 to 206 IU/L) were detected in 5 additional herd members. These horses appeared clinically normal, apart from 2 reports of nasal photosensitization and an aborted fetus. In 3 horses, high serum GGT activity persisted over a 44-day testing period. All affected horses had been given tetanus antitoxin within 12 hours of parturition, and a common source of vaccine was identified for 7 horses. Findings in this group of horses indicate that clinical and subclinical serum hepatitis can develop after administration of tetanus antitoxin.

A mouse mutant with glutathionuria was discovered by screening for amino acidurias in the progeny of ethylnitrosourea-mutagenized mice. Total glutathione concentration was increased in both blood and urine but decreased in liver homogenates from affected mice. Glutathionuric mice exhibited lethargy, severe growth failure, shortened life spans and infertility. gamma-Glutamyl transpeptidase activity was deficient in kidney homogenates of glutathionuric mice. The glutathionuric phenotype in these mice is inherited as an autosomal recessive trait. This mouse mutant will be a useful animal model for the study of gamma-glutamyl transpeptidase physiology and glutathione metabolism.

Three red kangaroos (Megaleira rufus), an adult male, an adult female, and a yearling, were exposed in bedding and food to coastal bermuda hay that contained the toxic plant Lantana camara. The adult male exhibited signs of anorexia, depression, lethargy, and jaundice. The adult female was presented dead. After 1 wk, following exposure to sunlight, the adult male and a yearling joey developed exudative dermatitis of the ear margins, eyelids, muzzle, and scrotum and opacity of the corneas. The adult male had a leucocytosis, anemia, bilirubinemia, bilirubinuria, hyperproteinemia, and elevated alanine aminotransferase, gamma glutamyl transpeptidase, alkaline phosphatase, and bile acid serum levels. Postmortem examination of the adult male revealed jaundice, and the liver was swollen, mottled, and pale yellow to reddish yellow. The gall bladder was markedly distended. Histopathologically, there was hepatocellular enlargement with vesiculation of the nuclei and sporadic feathery degeneration of the cytoplasm. The yearling joey survived and was treated symptomatically with i.v. fluids and antibiotics. The history, clinical signs, diagnostic findings, necropsy findings, and exposure to the toxic plant Lantana camara support the diagnosis of secondary photosensitization and hepatoxicity.

Following intravenous inoculation with horse blood-infected with the agent of human granulocytic ehrlichiosis (HGE) from a human fatality, two rhesus macaques (Macaca mulatta) exhibited pyrexia and lethargy on days 4-12 postinfection (PI). Hematology revealed neutropenia, thrombocytopenia, and anemia, with ehrlichial morulae in monocytes and neutrophils on days 4-12. Blood was polymerase chain reaction (PCR)-positive on days 4-12 and bone marrow was PCR-positive on day 11. There was a minor increase in gamma-glutamyl transpeptidase on day 12 and serum interferon-gamma levels increased by day 18. Seroconversion occurred on day 20 PI to a titer of 100 by day 22. Western blot bands characteristic of HGE included 25-, 44-, 80-, 94-, 105-, and 125-kD bands. There was generalized lymphohistiocytic infiltration in the liver, spleen, lymph nodes, and other tissues. The liver had focal hepatocyte apoptosis. There was HGE DNA (by PCR) only in the spleen. Comparable findings were not observed in a monkey that received uninfected horse blood as a control. This animal model of human disease is important for further studies of HGE diagnosis, management, and pathogenesis.

Hypothyroidism was diagnosed in 50 dogs and excluded in 86 dogs suspected of hypothyroidism, on the basis of the results of bovine thyrotropin response tests. Breed, pedigree, sex or neutering status did not significantly influence the likelihood of the dogs being hypothyroid. The hypothyroid dogs were significantly older than the non-hypothyroid dogs referred to the University of Glasgow during the same period. However, when dogs under two years of age were excluded from the statistical analyses there was no significant difference in age between the two groups. The most common clinical characteristics associated with hypothyroidism were metabolic signs (84 per cent of cases), particularly lethargy (76 per cent), obesity or weight gain (44 per cent), and exercise intolerance (24 per cent); and dermatological abnormalities (80 per cent), including alopecia (56 per cent), poor coat quality (30 per cent) and hyperpigmentation (20 per cent). When compared with the laboratory reference limits the most common biochemical and haematological abnormalities were increased concentrations of triglycerides (88 per cent), cholesterol (78 per cent), glucose (49 per cent), and fructosamine (43 per cent), and increased activities of creatine kinase (35 per cent), and decreased concentrations of inorganic phosphate (63 per cent), and a low red blood cell count (40 per cent). When compared with reference limits derived from the euthyroid dogs the most common abnormalities were increased concentrations of gamma-glutamyltransferase (21 per cent), cholesterol (18 per cent), and aspartate aminotransferase (15 per cent) and a decreased red blood cell count (29 per cent), and decreased neutrophils (18 per cent) and decreased activity of creatine kinase (15 per cent). Assessment of cholesterol, creatine kinase, aspartate aminotransferase, gamma-glutamyltransferase, and red blood cell and neutrophil counts may be particularly useful in distinguishing hypothyroid dogs from euthyroid animals with similar clinical signs.

Gadobenate dimeglumine formulation (E7155), at doses of 0 (physiological saline), 0.25, 0.5, 1 and 2 mmol/kg/day of body weight, was administered intravenously to male and female beagle dogs once daily for 4 consecutive weeks in order to evaluate the subacute toxicity of the test article. Reversibility of toxicity was evaluated during a 4-week recovery period at 1 and 2 mmol/kg/day. No toxicologically significant changes were observed at 0.25 and 0.5 mmol/kg/day. In animals receiving 1 or 2 mmol/kg/day, transient swelling and redness of the facial and eye areas, lethargy, decreased activity, emesis, retching, watery or unformed stool, decreased body weight or body weight gain, decreased food consumption, decreased hematocrit and hemoglobin concentration, increased APTT, increases in plasma ALP, GPT or gamma-GT, decreased plasma inorganic phosphorus, total protein or albumin, increased liver or kidney weight, subacute inflammatory infiltrates, loss of centrilobular hepatocytes or hepatocellular cytoplamic vacuolation in the liver, vacuoles in the epithelial cells of the renal tubles and/or hypocellularity in the bone marrow were seen. The results of toxicokinetic analysis showed that systemic exposure was similar in males and females, and there was no accumulation of the test material over the treatment period, although AUC tended to be enhanced by slightly more than the proportionate dose increase. These effects were recovered or tended to be reversed after a post-dosing period for 4 weeks. In conclusion, the No Observed Adverse Effect Level (NOAEL) was 0.5 mmol/kg/day.

A 10-year-old spayed female mixed-breed dog was presented to the Purdue University Veterinary Teaching Hospital (PUVTH) with complaints of persistent anemia with occasional exacerbations, anorexia, and lethargy. The dog had been presented to the referring veterinarian 2 months prior with multiple bite wounds received during a fight with 3 Pit Bull Terriers. The dog was discharged after the wounds were cleaned and surgically closed. Upon admission to the PUVTH, blood was collected for a complete blood count and biochemical analysis. Microscopic examination of peripheral blood smears revealed intraerythrocytic protozoal parasites consistent with Babesia gibsoni. Molecular analysis confirmed that the organism was B. gibsoni and that its 18S ribosomal RNA sequence was identical to that of other B. gibsoni isolates from Oklahoma, North Carolina, and Okinawa, Japan. Hematologic changes included moderately severe, regenerative, macrocytic, normochromic anemia, with poikilocytosis, polychromasia, anisocytosis, and a marked increase in nucleated RBCs. Biochemical changes included increased serum alanine aminotransferase, alkaline phosphatase, and gamma-glutamyltransferase activities. The dog was treated with imidocarb, but despite initial clinical improvement, the dog died 2 weeks after the first dose. A necropsy was not performed. The infection in this dog is the first reported case of B. gibsoni infection in Indiana. Because of the widespread geographical distribution of the organism, veterinarians and veterinary clinical pathologists throughout the United States should carefully examine Romanowsky-stained blood smears from patients with acute hemolytic anemia for small intraerythrocytic babesial parasites.
