The histopathological changes on the cardiac and skeletal muscles, and liver of rabbits fed commercial ration were observed. In the skeletal muscle, light microscopic changes observed were cloudy swelling, hyaline degeneration, atrophy, fragmentation and coagulative necrosis of muscle fibers, and proliferation of fibroblasts and infiltration of mononuclear cells. In the myocardium, loss of muscle fibers with necrosis and vacuolization, hyaline degeneration, hemorrhage and congestion were noted

This study was conducted to determine variations in the synthesis of DNA in the nuclei of various elements of the golden hamster (Mesocricetus auratus) placenta with increasing gestational age from the 8th day post coitum to parturition. The mitotic activities of the endodermal cells of the visceral yolk sac and of the parietal yolk sac, the trophoblastic cells of the labyrinth and the trophospongium and the giant cells were decreased with increasing gestational age. The placentation was nearly completed by 13 day of pregnancy and the increase in size of labyrinth was by appositional growth from the trophospongial cells

This study was conducted to investigate in the infection rate of common internal parasites in dogs in Kwangju area (Korea R.) from January to March, 1982. Dog's stools were collected from veterinary hospitals, houses, intensive dog-rearing places and sidewalks. On the basis of egg counting, of 464 fecal samples, 73.5% were appeared as positive. Dogs from veterinary hospitals and intensive dog-rearing places have higher infection rates than others. Of the parasites detected, Toxocara canis was the most commonly encountered (23.7%). Ascarids, flukes and coccidia were more prevalent in pups than in mature dogs, whereas hookworms were detected less often in young dogs than in older ones. There were significant (p0.01) differences among age categories for all parasites except tapeworms

An adult male rhesus monkey (Macaca mulata) developed anorexia, ataxia, dullness, coughing, and some elevated body temperature and ided a week after the initiation of such symptoms. Body weight was 18.3 kg and the only notable gross lesion was the appearance of acute pneumonia with multiple nodules. Histopathologic observation of the tissues obtained from this animal revealed the features of acute primary pulmonary blastomycosis

This study determines the diagnostic aid of serum gamma-glutamyl transpeptidase values in hepatitis, obstructive jaundice and pancreatitis in dogs. In CCl4 intoxication group, there were no significant changes in serum GGTP activities (mean:6.0-14.6IU.L). In bile duct ligation group, serum GGTP activities showed marded increases, beginning at postsurgical day 1 and rose to the highest mean value (342.7IU/L) on day 12. The activities never approached to base-line values. SGPT:GGTP ratio did not increase in bile duct ligation group, but increased markedly in CCl4 intoxication group

Paravertebral anesthesia for the operation of the abdominal wall in Korea [R.] cattle was effectively accomplished with a certain technique. The site of injection for blocking of ventral branches of the 13th thoracic nerve were approximately 5 cm lateral to the midline from the posterior edge of spinous process of the 13th thoracic vertebra and about 10ml of local anesthesia was injected immediately anterior to the transverse process of the first lumbar vertebra through this site. The block of ventral branches of the 1st and 2nd lumbar nerves were obtained by injecting 10ml of local anesthesia immediately below the posterior edge of transverse process of the 2nd and 4th lumbar vertebra, respectively
