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

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

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 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 clarify the presence or absence of isohemagglutinin and isohemolysin in the formosan deer. Using 4 rabbit immune sera to different deer blood cells following blood types were recognized among 30 heads of deer. These are by hemagglutination test (A: positive to all 4 immune sera (13 heads)), of 1BS and 3BS (8 heads), C: positive to the sera of 3BS, 7BS and 8BS but negative to that of 1BS (9 heads)), by hemolysis test (A: positive to all 4 immune sera (24 heads), B: positive to the immune sera of 7BS and 8BS but negative to those of 1BS and 3BS (3 heads)), C: positive to the sera of 3BS, 7BS and 8BS but negative to that of 1BS (3 heads))

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
