Sera components of dairy cows slaughtered as worthless were biochemically analysed, revealing deceased levels of albumin (Alb) and increased levels of glucose (Glu), aspartate aminotransferase (AST) and non-esterified fatty acid (NEFA), as compared to the levels of clinically healthy cows. The results suggested that these parameters were useful for the judgement of prognosis in dairy cows. By the cononical discriminant analysis, the worthless cows were shown to have physical conditions with specific AST, NEFA, and creatine kinase (CK) levels as well as nutritional conditions with specific Alb and total cholesterol (Tcho) levels.
Blood chemical values including ketone bodies were measured before and after surgical operation in 6 each Holstein-Friesian cows with abomasal displacement. The increased and decrecased levels of aspartate aminotransferase (AST), non-esterified fatty acid (NEFA) and ketone bodies (3-hydroxybutyric acid and acetoacetic acid) were observed before and after operation, respectively, suggesting that the onset of abomasal displacement was closely related to the increase of serum ketone bodies and NEFA. Total cholesterol level was unchanged before and after operation, and no definite tendency could be found in γ-glutamyl transpeptidase levels.
Using a commercially available kit, ID test · HN-20 Rapid, 18 hr cultures of 48 out of 54 (88.9%) Haemophilus somnus isolates from calves with pneumoniae or thromboembolic meningoencephalitis were correctly identified.
Four cats showing the estrous signs and behaviour after ovariohysterectomy were examined for the peripheral levels of estradiol-17β and progesterone by RIA during and after estrus. The changes of both steroid levels in all the cases examined were similar to those in normal female cats. In one case treated with human chorionic gonadotrophin (hCG) and chlormadinone acetate (CMA), the estrous behaviour was effectively controlled.
A 8-month-old Shiba dog with chronic anorexia and vomition was shown to have hepatomegaly by radiography and cystic dilation of the intrahepatic bile ducts by cholangiography. Contrast medium was accumulated within the renal medulla on intravenous urography, and ultrasonography revealed protrudent blood vessels within the dilated and cystic bile ducts. After euthanasia hyperplasia of cholangioepitheliocytes, hepatic fibrosis and dilation of the uriniferous tubules were observed histologically. These findings were similar to those observed in human Caroli desease.
The total tooth extraction was performed in 3 cats with gingivo-stomatitis. Radiographically no significant mandibular bone atrophy was seen at 1, 3 and 5-years after the treatment, and all the three cases showed normal eating behabior without any complications.
An epidemiological analysis of enterohemorrhagic E. coli from human cases in Yamaguchi Prefecture in 1996 was done using drug susceptibility patterns, plasmid profiles and pulsed-field gel electrophoresis (PFGE). Of 27 isolates, one was resistant to ABPC, SM and TC, while the other two were to TC and CP, respectively. By combination of PFGE and plasmid profile analysis, the isolates could be divided into 16 patterns, revealing that PFGE using several restriction endonucleases was useful for discrimination of different batcterial strains. Fifteen PFGE patterns were further divided into three groups, and 24 of 27 isolates were of the PFGE group I, suggesting that a single bacterial clone widely spread with variation in PFGE patterns.
In August 1984, a 6-year-old female Japanese cat, weighting 3.5 kg and kept in Yamaguchi City, was shown to have 7 eye worms on the conjunctiva, mostly in the conjunctival sac under the nictitating membrane. The cat developed no eye discharge, lacrimation, photophobia, conjunctivitis nor corneitis. All the worms were female and morphologically identified as Thelazia callipaeda.
