A 4-year-old cat was examined because of anorexia and lethargy. The cat became icteric within 3 days of admission. Values for aspartate transaminase, alanine transaminase, total bilirubin, alkaline phosphatase, and cholesterol were higher than normal. Radiography revealed hepatomegaly, with loss of detail in the cranioventral portion of the abdomen. Further diagnostic procedures were not permitted, and the cat was euthanatized. At necropsy, cholecystitis, cholangitis, and numerous choleliths were found. Cholelithiasis is a rare cause of obstructive jaundice in the cat.

Clinicians and nurses should obtain a history of antecedent illness occurring within 2 weeks of the onset of vomiting. Ninety percent of school-age children will give a history of an antecedent illness (varicella or influenza-like respiratory illness) within 1 week of the onset of vomiting. The vomiting of Reye's syndrome is usually persistent, lasting for 24 to 96 hours before the onset of serious brain signs. We believe that any child with the history of flu or chickenpox within 1 week of the onset of vomiting, which lasts for more than 12 hours, and is unusually severe or is associated with lethargy, should have an SGPT (alanine aminotransferase). This laboratory measure is clearly elevated in most cases of Reye's syndrome.

Groups of 8 male crossbreed domestic goats were given 3 dosage levels of aflatoxin B1 [(AFB1) mg/kg of body weight/day] orally: 0.1 for 34 days; 0.2 for 18 days; or 0.4 for 10 days. Clinical condition, feed consumption, and selected blood values were determined. Clinical signs of toxicosis included decreased feed consumption, slight-to-moderate loss of body weight, mucopurulent nasal discharge, dyspnea, coughing, lethargy, icterus, diarrhea (4 goats), and subnormal body temperature 24 to 48 hours before death. Clinicopathologic changes included increases in total RBC count, PCV, hemoglobin concentration, serum bilirubin concentration, and serum activities of aspartate aminotransferase, isocitric dehydrogenase, and ornithine carbamyl transferase. Goats given the 2 smaller dosage levels of AFB1 had slight increases of serum total protein (TP) concentration compared with control goats, but goats given the larger dosage levels of AFB1 initially had a slight decrease in TP. Aflatoxin had little effect on total WBC count. Serum alanine aminotransferase (ALT) activities in goats given the 2 larger dosage levels of AFB1 were similar to those of control goats, but goats given the smallest dosage level of AFB1 had increased serum ALT activities. Aflatoxin did not produce consistent dose-related changes in serum alkaline phosphatase activities. Seemingly, goats are susceptible to aflatoxin. Onset of clinical signs was dose-related. Onset and magnitude of increases in PCV, hemoglobin concentration, serum bilirubin concentration, and activities of serum aspartate aminotransferase, ornithine carbamyl transferase, and isocitric dehydrogenase were dose-related. Changes in TP and activities of serum ALT and alkaline phosphatase were neither dose-related nor were they potentially useful indicators of toxicosis.

Bile duct obstruction was induced in 6 cats by surgical ligation and transection of the common bile duct. Clinical and laboratory changes were monitored weekly for 25 to 54 days. Clinical signs of obstruction were similar in all cats and included anorexia, pyrexia, lethargy, intermittent vomiting, weight loss, palpable gallbladder, hepatomegaly, and bleeding tendencies. Tissue jaundice and acholic feces were evident grossly as early as postsurgical day (PSD) 4 with a mean onset of jaundice at PSD 5.3 +/- 0.4. Hematologic changes were initially characterized by a mild neutrophilic leukocytosis that increased with the chronicity of bile duct obstruction. Regenerative anemia developed in 4 cats associated with gastrointestinal blood loss. Acute serum biochemical changes were characterized by a marked increase in the mean values of aspartate aminotransferase, alanine aminotransferase, total cholesterol, and copper. Comparatively, only moderate increases in mean serum alkaline phosphatase activity were observed. Mean total bilirubin values increased remarkably at postsurgical week (PSW) 1, reaching a maximal value of 23.1 +/- 4.4 mg/dl at PSW 3 with 71.6 +/- 2.7% direct bilirubin. With chronicity of bile duct obstruction ranging from PSW 3 to PSW 7, the mean serum values of aspartate aminotransferase, alanine aminotransferase, total cholesterol, serum alkaline phosphatase, and total and direct bilirubin stabilized and then declined, whereas the increased mean serum copper values persisted. At PSD 25 to 54, hepatic copper values and serum bile acids were markedly increased. Seemingly, clinicopathologic changes of induced cholestatic hepatic injury depended largely on the duration of biliary obstruction.(ABSTRACT TRUNCATED AT 250 WORDS)

Adult female mink (Mustela vison) were fed a diet that contained Fusarium moniliforme culture material that provided dietary concentrations of 89 ppm fumonisin B1, 21 ppm fumonisin B2, and 8 ppm fumonisin B3 for 87 days. During the trial, there was mild lethargy in the mink fed fumonisins, but no other clinical signs or differences in feed consumption (measured during the first two weeks), body weights, or survivability were observed between the fumonisin-treated and control mink. Several hematologic parameters (mean corpuscular hemoglobin concentration, plasma total solids, and lymphocyte concentration) and serum chemical concentrations (globulin, phosphorus, potassium, blood urea nitrogen, creatinine, bilirubin, and cholesterol) and activities (alkaline phosphatase, alanine aminotransferase, amylase, and aspartate aminotransferase) were greater in the mink fed fumonisins than in the controls. Serum albumin/globulin and sodium/potassium ratios and chloride concentrations were lower in the fumonisin-fed mink than in the controls. The concentrations of free sphinganine and the ratio of free sphinganine to free sphingosine in the liver and kidneys of the fumonisin-treated mink were greater than in the control mink. No histopathologic alterations were associated with fumonisin treatment. These results indicate that long-term dietary exposure to F. moniliforme culture material containing 118 ppm total fumonisins is not lethal to adult mink, but can produce adverse physiological effects in the animals.

Erythema multiforme major and disseminated intravascular coagulation developed in a dog 24 hours after exposure to a d-limonene-based insecticidal dip. Clinical signs included severe lethargy and weakness, ulceration of the oral mucosa, and erythematous serpiginous, annular, and arciform lesions on the head, trunk, and limbs. Clinicopathologic abnormalities included leukocytosis with neutrophilia, normocytic normochromic anemia, thrombocytopenia, prolongation of prothrombin and partial thromboplastin times, increased fibrin degradation products, hypoproteinemia, hyponatremia, hypochloremia, azotemia, high serum alanine aminotransferase and alkaline phosphatase activities, and high serum bilirubin concentration. Despite intensive supportive care, the dog developed severe intrathoracic and abdominal hemorrhage and died. Necropsy revealed severe diffuse epidermal necrosis and widespread hemorrhage within organs. Insecticidal dips containing d-limonene have the potential to induce various toxic effects, including, possibly, erythema multiforme major, and should be used cautiously.

The medical and necropsy records of 41 cats diagnosed with nonlymphomatous hepatobiliary (NLHB) masses, including neoplasia and cysts, were reviewed. Overall, benign masses (n = 27) were more common than malignant ones (n = 14). The single most common malignancy was cholangiocellular carcinoma. The median age at diagnosis was significantly lower (P < .01) for cats with malignant rather than benign disease. Clinical signs associated with hepatobiliary neoplasia were usually vague and included lethargy, vomiting, and anorexia, often present for at least 2 weeks before presentation. Benign masses were an incidental finding in significantly more (P < .01) of the cases than were malignant masses. Median values for alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin were significantly higher (P < .05) in cats with malignant versus benign masses. The prognosis for malignant disease was poor, with 86% of the cats dying or being euthanatized during hospitalization. Cats with benign disease that underwent exploratory celiotomy were more likely to recover and warranted a more favorable prognosis than cats with malignant tumors. Factors associated with malignancy included age at presentation, presence of clinical signs at presentation, and specific serum chemistry changes.

Megaesophagus was diagnosed in 9 adult ferrets. Clinical history of the ferrets included regurgitation, difficulty in swallowing, partial anorexia, and lethargy. Cachexia, dehydration, weakness, and ptyalism were observed on physical examination. Radiography revealed the esophagus of each ferret to be dilated in the thoracic and cervical regions. Of 4 ferrets that had lymphocytopenia, 2 had concurrent leukopenia. Serum biochemical analysis revealed high activity of alanine transaminase (4 ferrets) and aspartate transaminase (3), and hypoglycemia (4). Treatment included administration of fluid, antibiotics, and agents directed against possible primary causes of megaesophagus. Treatments were ineffective, and all of the ferrets died or were euthanatized. All 6 ferrets that were submitted for necropsy had bronchopneumonia, hepatic lipidosis, mild esophagitis, and gastritis. The etiopathogenesis of megaesophagus in the ferrets was not determined.

Cytauxzoonosis is a rapidly and highly fatal disease in cats that is caused by the protozoan Cytauxzoon felis, which may be transmitted by Ixodid ticks (Dermacentor variabilis) from parasitemic bobcats (Lynx rufus). During an 8-year period, cytauxzoonosis was diagnosed in 8 cats, 7 cats within 14 months. Risk factors for these cats were warm weather, access to a wooded environment, and exposure to ticks. The most consistent clinical signs were acute lethargy, anorexia, decreased response to external stimuli (depression), icterus, dehydration, and capillary refill time > 2 seconds. Pertinent clinicopathologic findings were normocytic normochromic anemia, leukopenia, and thrombocytopenia; high serum concentrations of total bilirubin and glucose, low serum concentrations of albumin and potassium, high serum alanine transaminase activity; and, bilirubinuria. Confirmation of cytauxzoonosis was made by cytologic or histologic identification of the C felis organism. Splenic, lymph node, and bone marrow aspirates can provide an antemortem diagnosis when the number of parasitized erythrocytes is low on blood smears. Supportive treatment of 6 cats was temporarily palliative in some, but all 8 cats either died (3) or were euthanatized (5) when they became moribund. Survival time from observed onset of illness to death was < 5 days. Necropsy of 4 cats revealed predominately pulmonary involvement with venous congestion. Histologic examination revealed venous occlusion by parasitized mononuclear phagocytes in all tissue specimens, but only minimal inflammatory infiltrates.

1. GR95030X, a potent inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, was administered daily to marmosets by gavage. In a Maximum Repeatable Dose (MRD) study, doses of up to 30 mg kg-1 day-1 were administered for 49 days. In a chronic study, animals received dosages equivalent to 0, 1, 2.5, 7.5 and 20 mg kg-1 day-1 for 204 or 205 days. Some animals were maintained without treatment for a recovery period of 29 or 30 days. 2. Clinical signs included poor coat condition, weakness with impaired coordination, lethargy and other behavioural changes. There was also alimentary disturbance, and some deaths occurred at doses of 20 mg kg-1 day-1 and above. 3. Adverse effects upon body weight were seen although some recovery was apparent after the cessation of treatment. 4. Serum cholesterol concentrations were reduced. Very large increases in serum ALT, AST and CK activities were recorded with CK-MM isoenzymes accounting for 80% or more of the total CK enzyme activity. 5. Treatment was associated with muscle fibre atrophy and a sarcolemmal response with little evidence of regeneration. Histological examination revealed vascular changes, glial proliferation and cell death in the brain, with no consistent distribution. Alveolar capillary congestion and alveolar proteinosis indicated that there may have been a reduction in cardiac function. 6. HMG-CoA reductase inhibitors have evident potential to cause myopathy in marmosets. This is believed to be the first report of such an effect.
