JOURNAL FREE ACCESSPoor appetite, polydypsia and emaciation were observed in a yearling heifer of the Japanese Black breed. The urine was acid, ketonuric, and glycosuric. Blood chemical studies indicated hyperglycemia (230 mg/dl) and a high level of plasma NEFA (1.051 mEq /l).
The glucose tolerance test (GTT) was performed and characterized by glucose intolerance with an abnormally long half time. The plasma glucose recovered its initial level (300 mg/dl) after 6 hours. There was no rise in plasma insulin level (less than 6 μU/ml) in response to GTT.
Xylitol which is highly effective to activate insulin secretion was administered, but there was no rise in plasma insulin, either. When 200 units of lente insulin was administered, plasma insulin was raised to the level of more than 200μU/ml up to 6 hours and caused a decrease of plasma glucose to half of its initial level.
At necropsy, the pancreas was grossly normal. Microscopically, chronic pancreatitis was observed with lymphocytic infiltration into the interlobular and perivascular tissue and areas assumed to be pancreatic islets. As a result, most of the islets were atrophic to disappear eventually. Chronic glomerular and interstitial nephritis and central fatty degeneration of the liver were also found microscopically.
These findings showed that this case was a juvenile type of spontaneous diabetes mellitus in a cow.View full abstractDownload PDF (6008K) -

JOURNAL FREE ACCESSTrimelarsen (potassium pentyl thiarsaphenylmelamine) was tested for toxicity on adult dogs and mice. A total of 43 mice of the IVCE strain (9-11 weeks old) and 9 dogs (2-3 years old) were injected subcutaneously, intramuscularly or intravenously with 5 or 10mg/kg/day of trimelarsen in solution for 2 days. They were sacrificed 1, 2, 3 or 4 weeks after injection to prepare histological sections of the testes, which were stained with hematoxylin and eosin.
Degeneration of seminiferous epithelial cells and impediment of spermatogenesis were seen in about 50% of animals sacrificed 2 weeks after injection No histopathological changes were found in any seminiferous epithelial cell 3 weeks after injection.
These results suggest that trimelarsen may have an undesirable effect on the reproductive function in dogs. It seems advisable to inhibit the clinical use of trimelarsen in dogs for at least 4 weeks before mating.View full abstractDownload PDF (7606K) -

JOURNAL FREE ACCESSThree outbreaks of infectious bursal disease (IBD) were observed in a district of Kumamoto Prefecture from september to November in 1977. Symptoms and lesions were of IBD and specific antigen and antibody detected.
Respiratory symptoms, however, appeared in 2 outbreaks within 10 days after the first infected bird was recognized. In these outbreaks the duration of disease was prolonged and the fatality rate increased. Aspergillus fumigatus was isolated from the lungs and tracheas which had inflammatory and tuberculous lesions.
The significance of IBD as a predisposing factor of aspergillosis was discussed.View full abstractDownload PDF (3175K) -

JOURNAL FREE ACCESSIn June, 1976, male calves of a dairy breed were suffering from diarrhea on a farm. One of them manifested Symptoms of encephalitis. Salmonella enteritidis was isolated from its brain. Based on its clinical and pathological findings a diagnosis of meningoencephalomyelitis due to Salmonella infection was made on this calf. Sal.typhimurium, as well as Sal. enteritidis, was isolated from feces excreted by other calves on the same farm.View full abstractDownload PDF (4002K) -

JOURNAL FREE ACCESSIn this study 10μg/ml of nalidixic acid (NAD) was used singly, as well as a combination of 5μg/ml of NAD and 0.1% sodium deoxycholate or 1/100, 000 brilliant green dilution. Sodium deoxycolate and brilliant green were employed as inhibitors of aerobic Gram-positive bacteria.
There were differences in sensitivity to these agents among the strains of venereal type examined. The recovery rates were about 70 % or less of that determined with control medium. Two strains were inhibited on combined medium. These media must be examined in future for availability for isolation from natural outbreaks.View full abstractDownload PDF (3189K) -

JOURNAL FREE ACCESSA 2-year-old male shepherd was examined with an abnormal increase in appetite, emaciation, and persistent diarrhea as chief complaints. It had undigested fat and muscle fibers in feces and showed a negative trypsin test, a decrease in blood amylase and cholesterol level, and an increase in GPT. Abnormal results were obtained from fat absorption test and starch and glucose tolerance test. A diagnosis of chronic pancreatic insufficiency was made on this dog. The substitution treatment with pancreatic enzyme preparation had an effect in this case to improve clinical and hematological findings and the nature of feces rapidly and bring about a gradual increase in body weight.View full abstractDownload PDF (4680K) -
