A male Beagle dog weighing 9.5kg and estimated to be 5 years of age was presented to the authors' clinic in July, 1971. Paralysis appeared in its hind quarters in September, 1969. It cut itself by selfabuse in such manner in December, 1969, that it had no portion distal to the middle of the metatarsus of the right leg. The cut wound had been healed and locomotion was possible. Physical examination revealed a decrease in skin temperature in the lower portions of both legs. No pulse was felt at the femoral artery. Roentgenography disclosed arterial embolemia in the leg. The intradermal test was positive. In conclusion, the dog was diagnosed as a case of inveterate paradoxical embolemia caused by canine filariae and accompanied by an open condition of the foramen ovale. The diagnosis was verified by autopsy and histopathological examination.
A total of 286 samples of chopped meat were collected from meat shops in Tokyo. The viable bacterial count (72-hour value at 25°C) was in the order of 105 Or higher. It was 107 Or higher in almost 80% of the samples. Proteolytic bacteria occhpied almost 10% of all the viable bacteria. Fluorescent Pseudomonas was detected from all the samples, although rather low in count. In spite of such marked contamination, nothing abnormalw as revealed in the organoleptic test. Salmonella was detected from 17.1% of the samples. Contamination with it was the most frequent in pork, but not so intense in chicken. The most predominant were serotype B and Salmonella typhimurium. Almost 70% of the samples, particularly chicken samples, were contaminated with Staphylococcus aureus.
A needleless syringe (panjet by proprietary name) was used satisfactorily for inoculation of pigs with swine erysipelas vaccine, since a constant amount of bacteria was inoculated with certainty by means of it.
A tumor was found in the third-molar region of the left maxilla in a steer about 21 months old. Swelling occurred to the left maxilla. With bad prognosis, the steer was condemned. The tumor was about 11cm in diameter, showing a cauliflower-like appearance. It contained a hard bone-like structure, presenting odontogenesis. More than 10 hairs were grown in it. Its surface was affected with suppurative inflammation and had a cavity in it. Histological examination revealed adamantinoma originated from outer and inner enamel epithelium, odontoma accompanied by odontogenesis, and mesodermal fibromatous proliferation. As a result, this case was diagnosed as ameloblastic fibroodontoma.
A pH-telemeter was used to determine the hydrogenion concentration in the digestive tract of the dog continually. When a dog was starved, the pH ranged from 1.4 to 2.0 and from 5.5 to 7.9 in the stomach and intestine, respectively. When feed was given to this dog, the pH increased to 4.3 in the stomach, but showed no marked changes in the intestine. It also remained unchanged in the intestine even when a starved dog was fed after the radio capsule had been moved to this organ. This capsule stayed longer in the stomach when a dog was fed than when it was starved.
