Current belief that vitamin B6 deficiency causes depletion of muscle phosphorylase in animals appears to be erroneous. We present evidence that vitamin B6 deficiency is ineffective in reducing total phosphorylase in gasttocnemius muscle of young rats over a period of at least 8 weeks. Rats that had accumulated high levels of muscle phosphorylase while ingesting diets containing normal or excess amounts of the vitamin retained their phosphorylase after transfer to a vitamin B6 deficient diet. Prolonged deficiency did ultimately lead to enzyme depletion but this was after anorexia had developed and weight loss had occurred. When rats were partially starved for 1 to 4 days (fed 10% of normal energy intake) they lost muscle phosphorylase while retaining alanine and aspartate aminotransferases. When totally starved, the rats lost more phosphorylase than during partial starvation, but completely retained alanine aminotransferase, and lost some aspartate aminotrasferase. We conclude that the behavior of muscle phosphorylase is consistent with the Krebs-Fischer proposal that it acts as a reservoir for vitamin B6 and that starvation, but not vitamin B6 deficiency per se, causes depletion of muscle phosphorylase. It appears that phosphorylase may function as an adjunct ot adipose tissue necessary for the animal to efficiently meet the exigencies of starvation.

Urethral obstruction induced in adult male cats caused clinical signs identical with those observed in naturally occurring disease. Central nervous system depression, anorexia, dehydration, vomiting, muscle weakness, and hypothermia occurred. Weight loss (due to water loss and catabolism), metabolic acidosis, mild hyponatremia, hyperkalemia, hypermagnesemia, hypocalcemia, hyperphosphatemia, hyperglycemia, azotemia, and hyperproteinemia were also observed. Serum amylase, alkaline phosphatase, and alanine aminotransferase activities were normal. Ten of 13 cats (group 1), with 72 hours' induced obstruction but not treated with parenteral fluids, died either before the obstruction was relieved or within 8 days afterward. Eight cats (group 2) with induced obstruction for 49 to 98 hours developed severe clinical and biochemical alterations. Treatment with a multiple-electrolyte solution, in addition to relief of urethral obstruction, resulted in favorable clinical and biochemical responses. These cats survived and were clinically healthy at 9 to 10 days after relief of obstruction. It was concluded that use of a multiple-electrolyte solution to correct acidosis, restore circulatory volume, and enhance renal excretion of potassium was effective supportive therapy after urethral obstruction was removed.

Simian hemorrhagic fever (SHF) virus and a new strain of Ebola virus were isolated concurrently in recently imported cynomolgus monkeys (Macaca fascicularis) being maintained in a quarantine facility. Ebola virus had never been isolated in the U.S. previously and was presumed to be highly pathogenic for humans. A chronology of events including measures taken to address the public health concerns is presented. The clinicopathologic features of the disease were abrupt anorexia, splenomegaly, marked elevations of lactate dehydrogenase, alanine aminotransferase, and aspartate aminotransferase, with less prominent elevations of blood urea nitrogen, creatinine, and other serum chemistry parameters. Histologically, fibrin deposition, hemorrhage, and necrosis of lymphoid cells and reticular mononuclear phagocytes were present in the spleens of SHF and of Ebola virus-infected animals. Intravascular fibrin thrombi and hemorrhage were also present in the renal medulla and multifocally in the gastrointestinal tract. Necrosis of lymphoid and epithelial cells was occasionally noted in the gastrointestinal tract. The histopathologic findings considered specific for Ebola virus infection include hepatocellular necrosis, necrosis of the zona glomerulosa of the adrenal cortex, and interstitial pneumonia, all of which were generally associated with the presence of 1 to 4 mu intracytoplasmic amphophilic inclusion bodies. The disease spread within rooms despite discontinuation of all direct contact with animals, and droplet or aerosol transmission was suspected. Antibody to Ebola virus developed in animal handlers but no clinical disease was noted, suggesting a less virulent strain of virus.(ABSTRACT TRUNCATED AT 250 WORDS)

Nonhematopoietic hepatic neoplasms (n = 25) were diagnosed in 21 cats during a 5.5-year period. Thirteen of the neoplasms were benign bile duct adenomas and 12 were malignant, 6 of which were bile duct adenocarcinomas. All cats were greater than or equal to 10 years old, and 14 were male. Main clinical signs were anorexia and lethargy, and 15 of 21 cats had hepatomegaly. All 21 cats were feline leukemia virus-test negative. Although there was a trend toward high activities of serum alanine transaminase and aspartate transaminase, neither clinical signs nor enzyme activity were specific for diagnosis of hepatic neoplasia in the cats of this study.

The combination therapy with natural type human tumor necrosis factor (n-TNF; MHR-24) and human lymphoblastoid interferon-alpha (n-IFN-alpha; MOR-22) was investigated for antitumor effect against renal cell carcinoma in a multiclinic cooperative study throughout Japan. The "Response criteria of Japan Society for Cancer Therapy" were followed for the handling of subjects and the evaluation of antitumor effect. MHR-24 was administered at a daily dosage of 5,000-10,000 JRU by intravenous drip and MOR-22 at a dosage of 5,000,000 IU daily was administered intramuscularly at the same time. Both drugs were administered for 4 weeks or longer. A total of 36 patients were enrolled as subjects in the study. None of them were classified as ineligible. Five patients, were classified as imperfectly evaluable, and 31, as evaluable for the results of treatment. The responses in the evaluable patients were partial response (PR) in 4 patients, minor response (MR) in 3 patients, no change (NC) in 14 patients and progressive disease (PD) in 10 patients, with a response rate of 12.9%. Adverse reactions to the therapy were investigated in all 36 patients. The frequent subjective and objective reactions that occurred were fever, rigors and shivering, anorexia, and generalized malaise, and the frequent abnormal laboratory findings were leukopenia, thrombocytopenia, elevation of GOT, and elevation of GPT.

The characteristics of liver damage associated with the use of diclofenac, a popular nonsteroidal anti-inflammatory drug, were investigated by reviewing adverse drug reaction reports for Australia. Twenty six patients were reported for whom diclofenac was the sole suspected drug cause of their liver damage. The average age of the patients was 64 years (range 37-84 years); 19 (70%) were women. The most common clinical features were jaundice, hepatomegaly, anorexia, and nausea. Features of drug hypersensitivity were not reported. Duration of treatment with diclofenac before the onset of the illness ranged from 6-417 days (median 76 days). The most prominent biochemical abnormalities were raised serum aspartate transaminase and alanine transaminase activity of up to 30 to 40 times the upper limit of the normal range. Recovery generally started soon after withdrawal of diclofenac and the decrease in aspartate transaminase and alanine transaminase for the group was exponential, with half lives of around 13 days. The average total dose taken by 18 patients for whom accurate data were available was 8.7 g (range 1.4-63.5 g) and, unexpectedly, there was a significant relation between the logarithm of the dose of diclofenac and the logarithms of the peak and mean transaminase levels. Hepatocellular damage during treatment with diclofenac seems to be a rare event. From this analysis of Australian reports it seems that in a small subgroup of patients liver injury may be a direct toxic effect of diclofenac or a metabolite.

The medical records of 7 hypercalcemic cats with primary hyperparathyroidism were evaluated. Mean age was 12.9 years, with ages ranging from 8 to 15 years; 5 were female; 5 were Siamese, and 2 were of mixed breed. The most common clinical signs detected by owners were anorexia and lethargy. A cervical mass was palpable in 4 cats. Serum calcium concentrations were 11.1 to 22.8 mg/dl, with a mean of 15.8 mg/dl calculated from each cat's highest preoperative value. The serum phosphorus concentration was low in 2 cats, within reference limits in 4, and slightly high in 1 cat. The BUN concentration was greater than 60 mg/dl in 2 cats, 31 to 35 mg/dl in 2 cats, and less than 30 mg/dl in 3 cats. Abnormalities were detected in serum alanine transaminase, aspartate transaminase, and alkaline phosphatase activities from 2 or 3 cats. Parathormone (PTH) concentrations were measured in 2 cats before and after surgery. The preoperative PTH concentration was within reference limits in 1 cat and was high in 1 cat. The PTH concentrations were lower after surgery in both cats tested. A solitary parathyroid adenoma was surgically removed from 5 cats, bilateral parathyroid cystadenomas were surgically resected in 1 cat, and a parathyroid carcinoma was diagnosed at necropsy in 1 cat. None of the cats had clinical problems with hypocalcemia after surgery, although 2 cats developed hypocalcemia without tetany, one of which was controlled with oral administration of dihydrotachysterol and the other with oral administration of 1,25 dihydroxyvitamin D. All 5 of the cta that underwent removal of an adenoma were alive at least 240 days after surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

We conducted clinical studies on fleroxacin (FLRX), a new pyridone carboxylic acid derivative, for the treatment of periproctal abscess, secondary infections (due to wounds, burns or surgical operations), mastitis or areolitis and others with once daily dose of 200 mg or 300 mg. We obtained the following results. Clinical efficacy was evaluated in total 27 cases including periproctal abscess 11, secondary infection 8, mastitis or areolitis 6, phlegmon 1 and infected atheroma 1. Clinical efficacies were rated as excellent in 14, good in 9, fair in 4 cases. The overall efficacy rate was 85.2%. Bacteriological studies identified 14 strains of aerobic Gram-positive organisms, 12 of aerobic Gram-negative organisms and 6 of anaerobic organisms. The overall bacteriological efficacies were: eradicated in 26 strains, unchanged 2 and unidentified 4, hence the eradication rate was 92.9%. As for side effects, anorexia and nausea were observed in one of the 27 cases. In clinical laboratory tests, slight elevations of GPT and BUN were observed in 1 case each. We consider FLRX to be a useful antimicrobial agent at once daily dose for surgical infections.

A 49 year old female was started on disulfiram. Six weeks later she was given naproxen because of epicondylitis. After 5 days' treatment with naproxen she complained of nausea, anorexia and jaundice. At admission, bilirubin was 452 mumol/l, aspartate aminotransferase (ASAT) 1925 U/I, alanine aminotransferase (ALAT) 2815 U/I and prothrombin time measured as Normotest was 27%. The patient developed a fulminant hepatitis and died in hepatic coma almost four weeks after the introduction of naproxen. Postmortem examination disclosed a small liver (1,100 g) and histological examination showed massive necrosis and collapse of the lobules. The naproxen was the most probable cause of death, but it is impossible to exclude disulfiram as causative agent.

Okinawa prefecture is well known as an endemic area of Strongyloides stercoralis infection, and its recent infection rate was reported 6.2%, which was investigated by a new technique to detect S. stercoralis, agar plate method. Traditional treatment with thiabendazole was temporarily effective for S. stercoralis, but the recurrence rate was extremely high. We tried the new treatment for the purpose of complete eradication of the parasite. The patients were divided into two groups, who were given 500 mg of thiabendazole three times daily for 5 days and not medicated for the following 9 days. The medication was repeated 3 times in group 1 which consisted of 92 patients and 4 times in group 2 which consisted of 70 patients. Obtained results were as follows: 1) Six months after treatment, the cure rate was 89.5% in the only one course treatment, and 100% in more than 2 course treatments. 2) Side effects such as nausea, vomiting, anorexia or general fatigue were noted in 67.5% of all the patients after initial treatment, and 45.1% of the patients were dropped out of this trial. The dose of the drug was reduced in 32.1% of the patients, and only 22.8% were treated with full course of the regimen. 3) The elevation of S-GPT was observed in 33.8% of all patients. After initial treatment the rate was only 8.1%, but after 3 or 4 repeated course of treatments the rate was elevated to 39.0% and 45.4%, respectively. The liver injury was closely related to the total dose of thiabendazole and the period of the medication.(ABSTRACT TRUNCATED AT 250 WORDS)
