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

The modified drug sensitivity test for the shortening of detection time and clinical application was evaluated. Inhibitory zone in 6 strains of Staphylococcus and Escherichia coli tested to sensitivity test were reached at 100% between 2 and 6 hrs. The sensitivity test of Staphylococcus A.B and E. coli No. 2, No. 3 to antibacterial injection drugs in 6hrs after treatment were strongly positive (+++), and Staphylococcus A. A. and E. coli No. 1 were moderately positive (++). This modified method detected 86% degree of sensitivity between 7-12hrs after treatment

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

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

The histopathological changes in the mammary gland of lactating rats and rabbits injected with dexamethasone were observed. In the mammary glands of rats, the microscopic findings encounted were decrease of milk in the alveolar lumina, necrosis and dequamation of epithelial cells, atrophy of alveoli, proliferation of fibroblasts and thickness of alveolar walls, destruction of alveoli, presence of fat droplets within the glandular epithelial cells, infiltration of mononuclear cells and proliferation of adipose tissue, which were relative to the dose and duration of injection

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
