Jatropha curcas seed was fed to six calves at doses of 2.5, 1 and 0.25 g/kg once and to two other calves at 0.025 g/kg up to 14 days. The onset of toxic manifestations in the six calves was rapid and death occurred within 19 hours of administration. The two calves that received daily the lowest dose of J. curcas showed signs of poisoning and died within 10 to 14 days. The clinical signs of diarrhoea, dyspnoea, dehydration and loss of condition were well correlated with the pathological findings. There was an increase in aspartate aminotransferase, ammonia and potassium and a decrease in total protein and calcium in the serum of jatropha-poisoned calves.

The delay between the onset of symptoms and the call for help is the longest single component of the time taken for patients with acute myocardial infarction to come under coronary care and receive thrombolytic therapy. In order to investigate factors influencing patient delay, visual analogue scores for pain, shortness of breath, and anxiety were obtained retrospectively from 250 patients with acute myocardial infarction, for the time of onset of symptoms, and for the time of the call for help. The predominant symptom was chest pain, followed by anxiety and breathlessness. Although all symptoms increased in severity after their onset, the initiation of a call was largely unexplained in terms of worsening symptoms. Patient delay had a skewed distribution with modal, median and mean values of up to 1 h, 1.5 h, and 11 h respectively. Patient delay was negatively correlated with the pain score at the time of calling, but most of the variance of patient delay could not be explained in terms of symptom scores. However, patient delay was independently and negatively related to maximum serum aspartate aminotransferase. During acute myocardial infarction, patients with higher cardiac enzyme levels experience more pain and delay less. This tendency for patients with more severe infarction and a greater risk of death to call for help sooner is an added reason for administering thrombolytic treatment at the first opportunity: those patients who call early have most to gain from prompt therapy.

Effects of a single IM injection of selenium-vitamin E (Se-E; 5 mg of Se + 68 IU of alpha-tocopherol/60 kg of body weight) as a pretreatment 14 days before an oral dose of aflatoxin B1 (1.0 mg/kg) were studied in 24 dairy calves. Treatment groups were designated as follows: group 1 = no Se-E or aflatoxin B1 (control); group 2 = Se-E supplementation only; group 3 = aflatoxin B1 dose only; and group 4 = Se-E supplementation before aflatoxin B1 dose. Clinical signs of toxicosis in aflatoxin B1-treated calves included anorexia, ataxia, rough haircoats, increased respiration rates, dyspnea, dehydration, and nasal discharge. Packed-cell volume, RBC, WBC, and hemoglobin were increased in aflatoxin-treated calves. Significant increases in serum aspartate aminotransferase (P less than 0.05) and gamma-glutamyl-transferase (P less than 0.001) activities and prothrombin times (P less than 0.001) were observed in aflatoxin-treated calves, indicating that there was hepatic involvement. Although aflatoxin exposure caused a significant decrease in body weight (P less than 0.01) and feed intake (P less than 0.001) in treatment groups 3 and 4, Se was demonstrated to interact significantly (P less than 0.001) with aflatoxin B1 for feed intake, causing an improved feed intake in treatment group 4 calves.

A 7-year-old adult male ferret had progressive hair loss that was bilaterally symmetric. Also clinically evident were severe dehydration, polydipsia, muffled heart sounds, weak femoral pulses, hepatomegaly, lethargy, weakness, temporal muscular atrophy, dyspnea, and weakness. The blood profile of the ferret indicated profound leukopenia, eosinopenia, and high phosphorus, BUN, creatinine, and potassium concentrations, as well as high aspartate transaminase activity; the albumin concentration was low. The serum cortisol concentration was 8.1 micrograms/dl. Necropsy and histologic findings confirmed a diagnosis of hyperadrenocorticism, complicated by dilatative cardiomyopathy, chronic active hepatitis, and renal disease.

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.

Diarrhea, dyspnea, tympany, arching of the back, loss of condition, and loss of hair from the back were the prominent signs when Aristolochia bracteata was given orally to goats. The main lesions were hemorrhages in the lungs, heart, and kidneys, fatty change and congestion in the liver, mucoid abomasitis and enteritis and straw-colored fluid in serous cavities. An increase in aspartate aminotransferase activity, ammonia and urea concentrations and a decrease in the concentrations of total protein and magnesium were detected in detected in the serum.

This study evaluated long-term effects of 12 weeks of supervised training, of at least 45 minutes duration with two sessions per week, on physical performance and psychological well-being after myocardial infarction (MI). Sixty-nine patients were randomized to either an exercise or a nonexercise group. Maximum exercise capacity 6 weeks post-MI was inversely related to the acute peak aspartate aminotransferase values in serum, as an index of infarct size. One year post-MI, the increase in level of fitness (10%) in the training group did not significantly exceed (p = .10) that of the controls (2%). No intergroup differences were registered in self-rated psychological well-being and physical scores or in the return to work rate. In the training group, but not in the controls, the change in perceived dyspnoea at leisure-time activities was positively related to the objectively measured peak exercise capacity. We conclude that after MI only marginal improvements in physical performance are achieved 6 months after training is finished, with no long-term psychological benefits apparent versus a usual care program. The adaptive implications of supervised conventional exercise programs post-MI are therefore questioned.

An aqueous suspension of air-dried, hammer-milled leaf of Terminalia oblongata (yellow-wood) was administered to sheep by gavage, as a single dose of 5 to 20 g (dry weight)/kg body weight. Doses of 15 g/kg, or more, caused depression, inappetence, abdominal pain and reduced ruminal movements within 24 to 48 h and some sheep also showed dyspnoea, opisthotonus and champing of the jaws. Haematology and blood gas and acid-base measurements were unaffected. In sheep given a dose of 12.5 g/kg, or more, plasma osmolality, aspartate aminotransferase activity and potassium and bilirubin concentrations increased while plasma total protein markedly decreased and plasma sodium concentration and alkaline phosphatase activity remained normal. Most sheep were necropsied 48 h after dosing. The liver showed zonal hepatocellular necrosis, the pattern of which varied with the dose given. No renal lesions were observed, although one sheep given a very high dose became azotaemic and hyperkalaemic. Hydrothorax, hydropericardium and ascites developed in sheep given doses of 15 or 20 g/kg.

A total of 22 patients with superficial transitional cell carcinoma of the bladder, uncontrolled cystoscopically and unsuitable for or having failed intravesical therapy, received 50 mg. oral methotrexate per week for 12 months. Of the patients 7 (32%) achieved or remained in complete remission and 5 achieved a partial response, while 4 remained stable, 3 had progression and 3 were not evaluable. Patients who were still alive had a median followup of 2.5 years. Two patients with complete remission had relapse at 16 and 26.4 months, and 5 were disease-free at 34.5, 31.3, 18.6, 17.8 and 16.8 months, respectively. The methotrexate was generally well tolerated but 2 patients discontinued therapy because of dyspnea (1 subsequently died of respiratory failure that was possibly related to the methotrexate) and 1 because of persistent grade 2 mucositis. Grade 3/4 toxicities occurred in 3 patients: 1 each with reversible increases in creatinine and aspartate aminotransferase, and 1 with gastric bloating. There was little hematological toxicity. Reversible skin lesions developed in 4 patients. This oral treatment may provide an effective alternative to intravesical therapy but can be associated with severe toxicity.

A total of 42 birds from a flock of 104 farmed ostriches showed signs of toxicity after the accidental inclusion of monensin in their concentrate ration. The initial clinical signs were muscle weakness and ataxia which progressed to recumbency, dyspnoea and death, despite intensive supportive therapy. The serum activity of the enzymes creatine kinase, aspartate aminotransferase and lactate dehydrogenase was high in the affected birds, indicating significant muscle pathology. Few gross lesions were identifiable postmortem, but widespread lesions of degenerative myopathy were present at the histopathological level. However, these degenerative changes were restricted to the skeletal muscle and there was no evidence of cardiomyopathy in any of the birds examined. The birds were fed a ration which contained 215 to 224 ppm monensin for 13 days. New clinical cases ceased to occur shortly after the withdrawal of the source of monensin, but all the individuals which showed clinical signs of toxicity died or were euthanased on humane grounds.
