Forty-six cats with clinical haemobartonellosis were studied; 75 per cent of the cats of known age were two-and-a-half years old or younger, 50 per cent were intact males and 19.5 per cent were castrated males. The predominant signs of the disease were tachypnoea, lethargy, depression, anorexia, infestation with fleas, pale mucous membranes, icterus, emaciation, dehydration, splenomegaly, anaemia, leucocytosis, increased activities of alanine aminotransferase and aspartate aminotransferase, and azotaemia. Thirty-eight per cent of the cats that were tested for feline leukaemia virus (FeLV) antigen were positive, and 22 per cent of those tested for feline immunodeficiency virus (FIV) antibodies were positive. The prevalence of both FeLV and FIV was much higher than in the general Israeli cat population. The cats infected with both Haemobartonella felis and FeLV had a significantly lower body temperature, were more anaemic and the mean cell volume of their erythrocytes was greater than in the cats with haemobartonellosis alone.

This study was aimed to determine whether administration of an inhibitor of caspase-3 protects hepatocellular function in rats with hemorrhagic shock and whether caspases are important pharmacological targets in attenuating liver injury induced by hemorrhagic shock and resuscitation. Male adult rats were subjected to hemorrhagic shock by bleeding to a mean arterial blood pressure of 35-40 mmHg for 1 h and were then resuscitation with 60% shed blood and lactated Ringers solution. A subgroup of animals was injected i.v. with 2 mg/kg caspase inhibitor, Z-DEVD-FMK, prior to blood withdrawal. Fas ligand expression was markedly elevated and caspase-3 activity increased by 3-fold in hemorrhagic untreated rats. The increase in caspase-3 activity was prevented by administration of Z-DEVD-FMK prior to shock and resuscitation. Poly (adenosine diphosphate ribose) polymerase proteolysis was reduced in rats treated with the caspase-3 inhibitor compared with hemorrhagic untreated animals. Plasma aspartate aminotransferase and alanine aminotransferase values showed a significant increase at 6 h of shock in untreated animals (+360% and +515% as compared with sham-operated animals, respectively). Administration of the caspase-3 inhibitor did not prevent the increase in plasma transaminases. The cytosolic concentration of thiobarbituric acid-reactive substances (TBARS) and the oxidized:reduced glutathione ratio increased in the animals with hemorrhagic shock (+94% and +170%, respectively). These parameters were not significantly modified by pretreatment with Z-DEVD-FMK. It appears that caspase inhibition does not attenuate hepatocellular depression and liver injury induced by hemorrhagic shock and resuscitation.

A 37-year-old woman presented with increasing abdominal pain and jaundice. Six weeks before admission, she developed persistent diarrhea and jaundice of the skin. She also bruised easily, and her gums bled. In the subsequent weeks, her appetite decreased, she was fatigued, and she had nausea, vomiting, and abdominal distension. She had a history of drinking 1 quart of vodka every day for 20 years, with brief periods of abstinence; she stopped consuming alcohol 11 days before admission because it no longer provided symptomatic relief. Her past medical history was also notable for depression, including a suicide attempt 4 years earlier. She did not smoke, use illicit drugs, or have unprotected sexual intercourse. She had received no blood transfusions and had not traveled recently. She took no medications, except for occasional ibuprofen. On physical examination, she was thin and deeply jaundiced, and she trembled and responded slowly to questions. She was afebrile but tachypneic, and she had orthostatic hypotension. Her HEENT examination was notable for scleral and sublingual icterus, as well as crusted blood on her gums and teeth. The jugular veins were flat. The cardiac examination revealed tachycardia (heart rate, 103 beats per minute) without murmurs, rubs, or gallops. The abdomen was nontender and protuberant, with hypoactive bowel sounds; the spleen was not palpable, and there was no fluid wave or caput medusae. The liver percussed to 18 cm, with a smooth edge extending 10 cm below the costal margin. She had cutaneous telangiectases on her chest and bilateral palmar erythema. There was no peripheral edema. The neurologic examination was notable for asterixis. Her stool was guaiac positive. Laboratory studies revealed the following values: hematocrit, 21.2%; white blood cells, 17,310/mm(3); ammonia, 42 micromol/L; serum creatinine, 3.9 mg/dL; serum urea nitrogen, 70 mg/dL; albumin, 2.1 g/dL; total bilirubin, 26.8 mg/dL; alanine aminotransferase, 14 U/L; aspartate aminotransferase, 77 U/L; alkaline phosphatase, 138 U/L; prothrombin time, 103 seconds (international normalized ratio, 10.6); and urinary sodium, <5 mg/dL. Urinalysis revealed an elevated specific gravity and numerous muddy granular casts. Hepatitis A, B, and C serologies were negative. On abdominal ultrasound examination, there was no ascites, and the liver was echogenic. The portal and hepatic veins were patent, and the hepatic arteries were normal. The spleen measured 14 cm. What is the diagnosis?

Eleven native sheep, 1-2 years old, of both sexes were randomly divided into two groups, 6 sheep being allocated to the experimental group and 5 serving as controls. The sheep in the experimental group were fed 80% Tribulus terrestris and 20% alfalfa hay and wheat straw, while the control sheep were given a mixture of 40% alfalfa hay and 60% wheat straw. Clinical signs of hepatogenous photosensitivity were observed from day 11, including reddening and crust formation on the muzzle, nose, ears and eyelids, depression, weight loss, icterus, conjunctivitis, and yellow discoloration of the urine. Laboratory findings on weekly samples indicated significant differences (p < 0.05) in white blood cell count, total plasma protein and fibrinogen, total and direct bilirubin, blood urea nitrogen and creatinine concentrations, and aspartate aminotransferase and alkaline phosphatase activities. There were no significant differences in the packed cell volume, in the neutrophil, lymphocyte or eosinophil counts, or in the serum calcium, phosphorus, potassium, sodium or chloride concentrations. At necropsy of the experimental animals, there were various degrees of generalized icterus and the livers were swollen and discolored by bile pigment. Histopathological examination revealed varying amounts of crystalloid material in the bile ducts and renal tubules, hepatocellular degeneration, biliary fibrosis and proliferation, renal tubular necrosis and focal necrosis of cardiac muscle.

A study was conducted to evaluate the effects of ochratoxin A (OA) on Escherichia coli-challenged broiler chickens. Day-old broiler chicks were separated into two groups of 92 chicks each, with one group fed a control mash diet, and the other fed a mash diet containing 2 ppm OA. On day 14, each group was further separated into two groups, with one group inoculated with E. coli O78 (1 x 10(7) colony-forming units/0.5 ml), whereas the other group was not inoculated with E. coli. After E. coli inoculation on day 14, four birds from each group were euthanatized at 1, 2, 3, 5, 7, 10, 14, and 21 days postinoculation. Escherichia coli infection caused dullness, depression, huddling, and diarrhea. Mortality was 14.3% in chicks infected with E. coli but fed no OA. Mortality increased to 35.7% in chicks fed OA and infected with E. coli. Decreased body weight and reduced feed intake were observed in chicks fed OA, and the effects were more pronounced in chicks fed OA and infected with E. coli. Increased serum levels of aspartate aminotransferase, alanine aminotransferase, uric acid, and creatinine and decreased levels of total proteins, albumin, globulins, calcium, and phosphorus were observed in OA-fed birds. Escherichia coli infection did not cause significant alteration in any of the serum biochemical parameters. The presence of OA in poultry rations increased mortality and the severity of an E. coli infection.

The ethanolic rhizome extract of Kaempferia galanga L. (Zingiberaceae) was studied by conventional pharmacological methods including the Hippocratic screening test, and acute and subacute toxicities in rats. The hexane fraction was tested for dermal irritation in rabbits. The ethanolic extract, when tested by the Hippocratic screening test, demonstrated signs that indicated CNS depression such as a decrease in motor activity and respiratory rate, and a loss of screen grip and analgesia. In the acute toxicity test, oral administration of 5 g/kg of Kaempferia galanga produced neither mortality nor significant differences in the body and organ weights between controls and treated animals. Moreover, both gross abnormalities and histopathological changes were not comparatively detectable between all controls and treated animals of both sexes. In subacute toxicity studies, no mortality was observed when varying doses of 25, 50 or 100 mg/kg of ethanolic Kaempferia galanga extract were administered orally per day for a period of 28 days. There were no significant differences in the body and organ weights between controls and treated animals of both sexes. Hematological analysis showed no differences in any of the parameters examined (WBC count, platelet, hematocrit and hemoglobin estimation) in either the control or treated groups of both sexes. However, the differential leukocyte counts showed a slight but significant decrease of lymphocyte count in the 50 and 100 mg/kg male rat groups. In the blood chemistry analysis, no significant change occurred in the blood chemistry parameters, including glucose, creatinine, blood urea nitrogen (BUN), aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (Alk-P), total protein and albumin of both sexes. Pathologically, neither gross abnormalities nor histopathological changes were observed. No sign of irritation was observed during the dermal irritation test of the hexane fraction of Kaempferia galanga.

Ammi visnaga seeds and Artemisia herba-alba shoots were fed to 7-d-old Bovans chicks at 2% and 10% of diet for 9 w. The 10% A visnaga seed was toxic but not lethal to chicks and caused a consistently reduced body weight gain, inefficient feed utilization, enterohepatonephropathy, anemia, and alterations of serum aspartate transaminase and creatine kinase activities and cholesterol, total lipid and uric acid concentrations. The depression in growth and damage to vital organs of chicks fed 10% A herba-alba shoots 2% A visnaga seed, or 2% A herba-alba shoots were less marked.

Recent evidence indicates that activators of the serine/threonine kinase pathway protect against ischaemia/reperfusion. Here, we investigate the effects of renal ischaemia/reperfusion on the degree of renal dysfunction and injury with urocortin in rats. Rats treated with urocortin or its vehicle (saline) were subjected to bilateral renal artery occlusion (45 min) and reperfusion (6 h). At the end of experiments, the following indicators and markers of renal injury and dysfunction were measured: plasma urea, creatinine and aspartate aminotransferase, urine flow and creatinine clearance. Urocortin (1 or 15 microg/kg i.v.), administered 5 min prior to reperfusion, was not able to significantly reduce plasma urea, creatinine and aspartate aminotransferase indicating a non-protective effect on the renal dysfunction and reperfusion-injury caused by ischaemia/reperfusion. In addition, 15 microg/kg urocortin significantly depressed urine flow and creatinine clearance, which was associated with a significant depression in mean arterial pressure, indicating reduced renal perfusion. Thus, we propose that the pharmacological application of urocortin does not reduce the renal injury caused by bilateral renal ischaemia/reperfusion.

A 3-year-old Thoroughbred filly was referred to the Equine Hospital, Korea Racing Association for evaluation of hematuria, inappetite, weight loss and depression. From 25 days prior to admission, the horse was treated for right carpal lameness with 20 mg intramuscular administration of triamcinolone acetonide per day for consecutive 10 days by a local veterinarian. Clinical and laboratory findings included vaginal hyperemia, flare in bladder wall, neutrophilia, lymphopenia, polyuria, polydipsia and laminitis in the end. High activities of aspartate transaminase and gamma glutamyltransferase and high concentration of total bilirubin indicated hepatopathy. Further hematology, serum biochemistry and urinalysis did not reveal any abnormalities. Medical history, physical and clinicopathologic findings suggest that the laminitis and hepatopathy in this horse were most likely induced by repeated administration of exogenous corticosteroid. However, guarded prognosis of treating laminitis undermined the benefit of improvement of hematuria following electroacupuncture stimulation. The combined stimulation of kidney related acupoints (Shen Peng, Shen Shu), lumber related acupoints (Yao Qian, Yao Zhong) and associate acupoints (Guan Yuan Shu, Bai Hui) at 5Hz, 1-2V, for 40 minutes was of value in the treatment of hematuria. This case shows that horses under steroids may exhibit laminitis and steroid hepatopathy. Early recognition and good management of laminitis are important in the limitation of complications.

Ribavirin has recently been demonstrated to be efficacious in combination with interferon (IFN) alpha-2b for the treatment of relapsed hepatitis C infections. The aim of this study was to evaluate the relationship between the pharmacokinetics and adverse reactions of ribavirin when ribavirin plus IFN alpha-2b were administered to patients affected with chronic hepatitis C. Nineteen patients received intramuscular IFN alpha-2b at a dose of 6 or 10 million units and oral ribavirin at 600 mg or 800 mg daily for 24 weeks. The pharmacokinetic profiles of ribavirin were assessed by the measurement of plasma concentrations. Twelve patients were continuously given both ribavirin and IFN alpha-2b, whereas in 7 patients the therapy was discontinued due to severe adverse drug reactions such as skin eruption, anemia and depression. There were no significant differences in ribavirin dose, Hb, ALT and AST values between the continued and the discontinued therapy groups. In contrast, the pretreatment platelet level and patient age of the discontinued therapy group were significantly different to the continued group. The trough plasma concentration of ribavirin in the discontinued therapy group was significantly higher than that in the continued group at week 1. These results suggest that the monitoring of plasma ribavirin concentrations may be valid for predicting the early phase of adverse drug reactions, thereby providing useful information for the adjustment of the ribavirin dosing for each patient.
