Sheep received a single intragastric dose of 0.5, 1.0, 1.5, or 2.0 mmol F-/kg. Mild signs occurred at 1.5 mmol F-/kg and the animals recovered 2 days later. With the 2.0 mmol F-/kg dose all animals showed dullness, anorexia, and mild diarrhea which decreased from the third day. Dose-related congestion of duodenum, liver, kidney, and lung was observed in all animals. For the two higher doses kidney degeneration and tubular necrosis were associated with glomerular inflammation. Serum fluoride had a dose-related increase and was still significantly elevated on Day 7 for sheep given doses higher than or equal to 1.0 mmol F-/kg. Serum calcium and glucose levels were significantly lowered for all doses on the first day and the decrease was dose-related. In sheep given 2.0 mmol F-/kg total proteins and sodium were significantly lowered, whereas potassium and urea were increased (p less than 0.05); alkaline phosphatase (ALP) and lactic dehydrogenase (LDH) were both lowered (p less than 0.01) on the first day and ALP was still lowered on Day 7. For the highest dose glutamate dehydrogenase (GDH) was increased on Days 1 and 7 and gamma-glutamyl transferase (GGT) was increased on Day 1 and lowered on Day 7. Diuresis was increased for the two higher doses in Day 3 or 4 following dosage. A dose-related increase of daily fluoride excretion occurred for all doses on Day 1 and fluoride excretion was still significantly elevated on Day 7 except for the lowest dose.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty cows from a dairy herd consisting of 60 healthy, lactating Holsteins developed clinical signs of anorexia, mental derangement, dehydration, recumbency, and ruminal atony after ingesting water containing blue-green algae. Of the 20 cows, 9 died. The algal bloom, which developed in a stagnant pond during hot, dry weather, was identified as the cyanobacterium Microcystis aeruginosa, a potentially hepatotoxic algae. One week after the onset of toxicosis, affected cows seemed healthy, although liver-associated enzyme activities (alkaline phosphatase, gamma-glutamyl transferase, aspartate transaminase, and lactate dehydrogenase) were increased. Intraruminal administration of the intact wet bloom to a healthy 125-kg Angus heifer was followed by hepatic necrosis and death. The liver was large, friable, and gun-metal blue, with microscopically evident hepatocyte dissociation, degeneration, and necrosis. The ingesta of the heifer contained typical clumps of cells that were identified as M aeruginosa. The intraperitoneal administration of lyophilized cell material from that bloom to 18 mice caused marked hepatic enlargement. The intraperitoneal median lethal dose of the dried bloom was estimated to be 10 mg/kg of body weight. A cyclic peptide toxin purified from the algae seems to be similar structurally to toxins from other characterized hepatotoxic blooms of M aeruginosa.

One splenectomized and 6 intact coyotes (Canis latrans), and 2 coydogs were experimentally inoculated with a recent isolate of Babesia gibsoni. The disease was mild in intact animals, was fatal in the splenectomized coyote, and was characterized by a regenerative hemolytic anemia with the PCV decreasing to 16% in intact animals and to 6% in the splenectomized coyote. Peak parasitemia ranged from 3% to 21% of erythrocytes infected and was inversely correlated to PCV. Serum lactate dehydrogenase, bilirubin, and globulin concentrations were increased in all infected animals. Three weeks after inoculation, specific antibody titers increased to 1:65,536 and remained elevated in the chronically infected animals. The splenectomized coyote had progressive weakness until death, 24 days after inoculation. Intact animals had splenomegaly and anorexia at the height of infection. The splenectomized coyote had generalized edema, omental petechiae, renal and hepatic degeneration, membrano-proliferative glomerulonephritis and congestion, extramedullary hematopoiesis, lymphoid hyperplasia, and severe hemosiderosis in an accessory spleen. The only consistent change in the intact animals was splenomegaly.

Infectious bursal disease in 35-day-old specific-pathogen-free (SPF) chickens was characterized clinically by its acute onset and brief duration. Clinical signs included depression, anorexia, diarrhea, and polyuria. A detectable precipitin antibody response occurred between 3 and 5 days postinoculation. Evaluation of pooled serum samples obtained from infectious bursal disease virus (IBDV)-infected chickens revealed transient changes in potassium, cholesterol, uric acid, lactate dehydrogenase, serum glutamic-oxalic transaminase, and serum proteins. Individual serum samples analyzed for uric acid concentration indicated that several IBDV-infected chickens had serum uric acid concentrations above the normal comparison range. Histopathologic examination of lymphoid and nonlymphoid tissues from IBDV-infected SPF chickens affirmed that the predominant lesion was lymphoid necrosis in the bursa of Fabricius. Other lymphoid organs were much less severely affected and possessed greater regenerative potential. Nonspecific and relatively mild changes were found in the liver and kidney: hepatic lipidosis and necrosis, renal intratubular crystalline deposits (probably urates), and increased ectopic lymphoid foci. There was no evidence of immune-complex-mediated arteritis/vasculitis in the sartorius muscle or any other tissue examined. Histopathologic and ultrastructural evidence of glomerulonephritis was rare but compatible with acute immune complexemia.

A 50-year-old black female developed hepatic dysfunction secondary to captopril therapy, 25 mg tid for one month. Liver biopsy showed primarily cholestasis, with secondary hepatocellular elements. Symptoms consisted of jaundice, pruritus, anorexia and weight loss, hepatomegaly, and abdominal tenderness. Total bilirubin, alkaline phosphatase, lactate dehydrogenase (LDH), and serum glutamic-oxaloacetic transaminase (SGOT), reached highs of 506 mumol/L, 737 U/L, 319 U/L, and 100 U/L, respectively. Recovery was slow, but complete, after discontinuation of the drug.

Clinical sarcocystosis was studied in 37 goats after inoculation with graded doses of sporocysts of Sarcocystis capracanis. Eight uninoculated goats served as controls. Clinical response varied with the dose. Goats inoculated with 10-40 million sporocysts died between 11 and 13 days after inoculation (DAI), from interstitial pneumonia, vasculitis, and necrosis of mesenteric lymph nodes. All goats inoculated with 100,000 or 1 million sporocysts died between 19 and 23 DAI; clinical signs were anorexia, fever (40-41 C), anemia, and weight loss. Four of 4 goats inoculated with 50,000 sporocysts and 1 of 4 inoculated with 10,000 sporocysts died 24, 28, 39, 68, and 61 DAI, respectively. Goats inoculated with 1,000 sporocysts and uninoculated goats remained clinically normal. After day 18 and before day 68, packed cell volume and hemoglobin content decreased to as low as 11% and 3.6 g/dl, respectively. Alanine aminotransferase and lactic dehydrogenase activities were inconsistently increased. Blood urea nitrogen and bilirubin values were increased, reaching as high as 63 mg/dl and 10 mg/dl, respectively. Histologically, thymic atrophy, vasculitis, hepatitis, cholangitis, myocarditis, generalized myositis, and encephalomyelitis were the main microscopic findings. The cause of the anemia in goats that died after day 19 was not determined.

The medical records of 52 patients from the University of Wisconsin Hospital and Clinics with carcinoma of the gallbladder were examined retrospectively. The cases were reviewed for factors in their medical history, presenting physical examination, laboratory data, therapy, pathological grade, and histology that might effect median survival. Only a prior complaint of anorexia, an elevated lactic dehydrogenase (LDH), or advanced pathologic stage at time of diagnosis provided significant prognostic information. Combining pathologic stage and histologic grade additively provided the most significant prognostic information [1]. Division of gallbladder carcinoma patients in future clinical trials by this combined (stage and grade) stratification scheme may prove helpful in assessing the efficacy of new therapies. The knowledge that anorexia and elevated LDH are poor prognostic findings may assist physicians in counseling patients with this malignancy.

A 2-year-old spayed female Siamese cat was presented with clinical liver disease characterized by anorexia; depression; elevations in serum levels of alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase; hyperbilirubinemia; and icterus. Liver biopsy diagnosed hepatocellular degeneration with marked centrilobular hepatocellular accumulation of rhodanine-positive brown granules. Subsequent postmortem examination revealed similar granular material in the epithelium of the proximal convoluted tubules and collecting ducts of the kidney and alveolar epithelium and macrophages in the lung. The liver and kidney copper concentrations were 4,074 and 792 ppm dry weight, respectively. Hepatic degeneration in this cat apparently was due to excessive accumulation of copper.

We described a case of adult T cell leukemia (ATL) not associated with human T-cell leukemia virus type I (HTLV-I), a clinical entity that was first reported by Shimoyama et al. A 79-year-old male was admitted with anorexia and fever in October, 1989. Physical examination revealed marked hepatosplenomegaly and superficial lymphadenopathies. Hematological examination revealed marked leukocytosis (136,300/microliters) with abnormal lymphoid cells showing highly lobulated nuclei. Hypercalcemia (11.2 mg/dl) and elevation of lactic dehydrogenase were also recognized. Surface marker analysis showed that the abnormal lymphoid cells in the peripheral blood were positive for CD2 and CD4 but negative for CD8. Southern blot analysis of the DNA from peripheral blood leukemic cells revealed monoclonal rearrangement of T-cell receptor beta-chain gene. The clinical and hematological findings of the patient were compatible with those of acute type ATL, however, serum anti-HTLV-I antibody was negative and HTLV-I proviral DNA was not detected in the leukemic cells by Southern blot analysis. Furthermore, the polymerase chain reaction showed no integration of the HTLV-I proviral DNA in the leukemic cells.

A 78-year-old woman was admitted to our hospital because of disorientation and fever on January 21, 1992. Two days before admission she experienced vomiting, anorexia and general malaise. Laboratory examinations on admission disclosed a hemoglobin level of 11.1 g/dl and a platelet count of 8,000/microliters. The peripheral blood smear revealed anisocytosis with numerous schistocytes and poikilocytes. Polychromatophilic and nucleated red blood cells were also seen, and the reticulocyte count was 38/1000. Her serum lactate dehydrogenase (LDH) value was 2,977 WU and the total serum bilirubin level was 3.5 mg/dl with 2.7 mg/dl indirect reacting fraction. Serum creatinine was 4.7 mg/dl. Her consciousness became semicomatose after a systemic seizure which lasted approximately 15 seconds and her hemoglobin level decreased to 8.5 g/dl on hospital day 2. Therefore, we diagnosed her as having thrombotic thrombocytopenic purpura (TTP) because of the presence of all 5 features, that is, thrombocytopenia, microangiopathic hemolytic anemia, fluctuating neurologic abnormalities, renal dysfunction and fever. A plasmapheresis with fresh frozen plasma (FFP) replacement was begun on that day. She was also treated with anti-platelet agents, 80 mg/day aspirin, and 300 mg/day dipyridamole. Moreover, packed red blood cells (PRC) were infused. While also receiving diphenylhydantoin and phenobarbital to prevent convulsions, status epilepticus developed on day 3. Because of inhibited spontaneous respiration which was an adverse effect derived from diazepam and sodium thiamylal administered intravenously to treat the status epilepticus, an artificial respiration was initiated.(ABSTRACT TRUNCATED AT 250 WORDS)
