  • A 8 months old, female domestic Shorthair cat with long-term signalment of anorexia, lacrimation, uveitis and coughing was submitted to the Pathology and Diagnosis Reference Division, NVRQS, Korea, for necropsy. Main gross lesions were characterized by ascities, some grayish-white nodular formation and fibrous adhesion on the surface of visceral organs including liver and kidney. Principle histopathological findings were fibrinous serositis, multifocal granuloma and necrosis, vasculitis, perivasculitis in various pharenchymal organs. Paraffin-embedded tissue sections taken from most of organs with granulomatous lesions were confirmed specific reaction to the monoclonal antibody of feline infectious peritonitis virus in the cytoplasm of many infiltrating macrophages by immunohistochemistry. The report was to describe the pathological lesions of the first naturally-occuring FIP case in companion cat of Korea.

  • The single dose toxicity of Hwangiaegongjinbo, an invigorator developed by Korea Medical Science Institute was evaluated in ICR mice and Sprague-Dawley rats. The aqueous solution of freeze-dried powder of Hwangiaegongjinbo or its original solution was once administrated orally to both sexes of mice and rats at dose of 2000 mg/kg, the recommended upper limit dose for acute toxicity. Water was administered to another group as control. after single adminstration, sign of toxicity were observed every hour for the first 6 hours and every day for 14 days. Neither sign그cant toxic sign nor death was observed during the observation period. In addition, no pathological changes were noticed in macroscopic examination at necropsy in those treated group. These results indicated that $LD_{50}$ of Hwangiaegongjinbo is greater than 2000 mg/kg in ICR mice and Sprague-Dawley rats.

  • KH-502 (Flupyrazofos), a new organophosphorus insecticide synthesized by Korea Re-search Institute of Chemical Technology, was found to be effective against diamond-back moth(Plutella xylostella). This study was carried out to determine the acute toxicity of KH-502 in Sprague-Dawley rats and ICR mice. The test article was orally or dermally administered to the animals. Death, tremors, salivation, lacrimation, abnormal gait and corneal opacity were observed. Decrease in body weight gain was observed in all treatment groups. At necropsy, dark red coloration of lung, enlargement of adrenal glands and atrophy of spleen were observed. The oral $LD_{50}$ value was 372 mg/kg in male rats, 605 mg/kg in female rats, 186 mg/kg in male mice, and 115 mg/kg in female mice. And the dermal $LD_{50}$ was 4086 mg/kg in male and 3881 mg/kg in female rats.

  • The effects of continuous administration of tiletamine-zolazepam(T-Z) on the blood, liver and kidney of dogs were evaluated. The drug was repeatedly administered into ten mongrel dogs intramuscularly at dose of 10mg/kg for every seven days. Hematology(PCV, WBC, RBC, TP, Fibrinogen) and serum chemistry(ALT, AST, BUN, Creatinine) were monitored for 14 days postinjection. No significant changes in PCV values, total RBC counts and plasma total protein values was found. Total WBC counts and fibrinogen values were significantly increased from 2 days to 7 days postinjection. There was no significant change in ALT, AST, BUN and creatinine levels. All animals were euthanized and necropsied at 14 days postinjection. No gross lesion and pathologic lesion was found on liver and kidney in necropsy finding.

  • Objectives: This study was performed to examine the single-dose toxicity of Samgihwalryeok pharmacopuncture. Methods: Forty six-week-old Sprague-Dawley (SD) rats were divided into four groups of 10 rats each; each group was then sub-divided into two smaller groups, one of five males and the other of five females. Group 1 (G1, control) received 1.0 mL of normal saline solution, while group 2 (G2, low-dose group), group 3 (G3, mid-does group, and group 4 (G4, high-dose group) received 0.1, 0.5, and 1.0 mL of Samgihwalryeok pharmacopuncture, respectively. Results: No mortalities or clinical signs were observed in the four groups. Also, no significant changes in body weights were observed among the group, and no significant differences in hematology/biochemistry, necropsy, or histopathology results were noted. Conclusion: The above findings suggest that treatment with Samgihwalryeok pharmacopuncture is relatively safe. Further studies on this subject are needed.

  • Effects of ($\pm$)-camphor on liver cytochrome P450 enzymes were investigated in male ICR mice. Mice were treated intraperitoneally with 0, 200, 400 and 800 mg/kg of ($\pm$)-camphor in corn oil for 3 consecutive days. Twenty four hr after the final treatment, the animals were subjected to necropsy. The activities of serum aspartate aminotransferase and serum alanine aminotransferase were slightly changed by the treatment with ($\pm$)-camphor at the doses used. Administration of ($\pm$)-camphor to mice significantly induced the hepatic activities of pentoxyresorufin O-depentylase and benzyloxyresorufin O-debenzylase and weakly induced ethoxyresorufin O-deethylase in dose-dependent manners. The present results suggested that ($\pm$)-camphor might act as a relatively specific inducer of hepatic cytochrome P450 2B in male ICR mice.

  • The subacute toxicity of combined antibiotics, SP-102 (Sulbactam.Piperacilline), was examined in S.D.rats. Four groups of rats were administered intraperitoneally with 0, 512, 1280 and 3200 mg/kg/day of SP-102 for 30 days. Hain clinical sign related to the compound was soft stool. The body weight gain was slightly decreased in male rats treated with 1280, 3200 mg/kg and in female rats treated with 1280 mg/kg of SP-102. Water consumption was significantly increased in rats administered with SP-102. There were no dose-related changes of urinalysis, biochemical examination and hematological findings in all the groups treated with SP-102. Gross necropsy and histopathology revealed no evidence of specific toxicity related to SP-102. Our data indicate that no-observed effect level of SP-102 is below 512 mg/kg in male and female rats. Maximum tolerated dose of SP-102 was estimated to be above 3200 ma/kg in this study.

  • DA-125, a new anthracycline antitumor antibiotic, was administered to Sprague-Dawley rats intravenously for 4 weeks to investigate the repeated dose toxicity Focal alopecia was noted in three female rats receiving 1.0mg/kg/day. In rats receiving 1.0 mg/kg/day, weight gain decreased in both sexes after first or second week. Hematological examination revealed lower counts of total leukocyte and increased numbers of platelet after second week. At terminal necropsy, atrophy of thymus and spleen was observed. Lymphocytic depletion of thymus and atrophy of white pulp in spleen were observed microscopically. A decrease in the number of hematopoietic cells in the bone marrow and degeneration of germinal epithelia in testes were also observed. These treatment-related effects were mainly confined to rats receiving 1.0 mg/kg/day. And toxic effects with microscopic changes were not observed in rats receiving 0.2 mg/kg/day or 0.04 mg/kg/day.

  • A 3-year-old female jaguar (Panthera onca onca) died after having 1 day history of respiratory failure. At necropsy, the pericardial sac contained large amounts of cloudy fluid enriched with fibrin. Numerous yellowish nodules, which are variable in size and often confluent, are randomly scattered throughout the myocardium. Pasteurella haemolytica was isolated from the pericardial sac and myocardium. In the lung, severe pulmonary congestion, edema and vasculities with intralesional presence of heartworm were found. Therefore the cause of death in this jaguar is believed to be due to respiratory failure following concurrent heartworm infection and bacterial pericarditis and myocarditis.

  • A necropsy of a primiparous, 4-year-old, Himalayan tahr (Hemitragus jemlahicus) was performed in September 8, 2009. Typical appearances of ovaries, oviducts, uterine horns, cervix and caruncles were well shown. Five cervical folds were present in the cervix. Cervical opening can be reached in the length of less than 15 cm from the entrance of vagina. Development of two follicles was found in the left ovary even though breeding season of this species naturally starts in late November. The reproductive organs of a primiparous, 3-year-old, Corriedale sheep showed that differences in the length and morphological appearance of cervix exist between two species. Comparative understanding of reproductive systems in Himalayan tahr and Corriedale sheep could help advancing assisted reproductive technologies in feral goats.
