A 5-year-old, 6.2 kg male mixed dog was presented to local animal hospital with a 6-month history of swelling, pain, inflammation, and lameness in the 5th digit of right hind limb. And a 7-year-old, 2.7 kg male Maltese dog was also presented to animal hospital with a 2-month history of nail deformities in the 5th digit of left hind limb. Abnormal growth or degeneration of the distal phalanges was observed at the 5th digit of hind limb in two dogs using radiographic examination. The masses in the digit were excised completely under local anesthesia. On histological examination of the digit masses, large well-circumscribed, unencapsulated round or irregular cystic neoplasms with/without inflammation were occupied in or adjacent area of the distal phalanx. These cysts were lined by stratified squamous epithelium that occasionally had a prominent granular cell layer. Based on the history, clinical signs, radiographic, gross and histopathologic features, these cases were diagnosed as nailbed epithelial inclusion cysts in the digit of dogs.

The purpose of this study was is to investigate the arthritis treatment and prevention of the effects the herbral administration to experimental animals induces arthritis 4 weeks for medicinal herbs (Scutellaria baicalensis Georgi, Acanthopanacis cortex, Achyranthis Radix). To investigate the prevention of histopathological examination and molecular biological examinations for arthritis improvement in vivo New Zealand, white rabbits were divided into a normal (Normal, n = 7), or a collagen-induced arthritis (CIA, n = 7), or a collagenase injection and medicinal herbs (SAA, n = 7). It was confirmed that induced arthritis was treated with Gross examination, and the measurement of average arthritis index (MAI) and improved arthritis by medicinal herbs. TNF-${\alpha}$ and IL-$1{\beta}$ were significantly increased in the CIA and SAA groups, compared to the normal group (p < 0.05). MMP-1 and TIMP-2 were significantly increased in the CIA, compared to the other groups (p < 0.05). MMP-1 and TIMP-2 were significantly decreased in the SAA group, compared to the CIA group (p < 0.05). As a result, Herbal administration used in this study might be able to help in the treatment of arthritis induced by inflammatory and immunosuppressive effects, that which can be expected.

Two female Yorkshire terrier was referred to Veterinary Medical Teaching Hospital, Seoul National University. In case 1, clinical signs were vomiting, anorexia and weight loss. Cystic intraabdominal mass was identified in radiographic and ultrasonographic examination. In case 2, clinical sign was abdominal distension. In radiographic and ultrasonographic examination, cellular ascites and bilateral intraabdominal masses next to kidneys were observed. Many clusters of glandular epithelial cells with anisocytosis, anisokaryosis, high N:C ratio coarse chromatin and prominent nucleoli were shown in cytologic examination of sanguineous ascites. In all two cases exploratory laparotomy was performed and enlarged ovaries were observed (Rt: 6$\times$5$\times$5 cm and Lt: 3$\times$2$\times$1 cm in case 1 and 3$\times$2$\times$1 cm bilaterally in case 2). After ovariohysterectomy histopathologic examinations were performed. Histopathologically the masses were diagnosed as ovarian adenocarcinoma and ovarian cystadenocarcinoma in case 1 and case 2, respectively. In both dogs no further chemotherapy was carried out. These two dogs had no gross evidence of tumor recurrence at the time of 3 months after tumor resection, but long-term follow-up might be needed.

DA-3585, a biosynthetic recombinant human erythropoietin has been developed as a treatment for anemia associated with chronic renal failure in Dong-A pharmaceutical Co. Ltd. This study was carried out to assess its acute and subacute toxicities in rabbits. DA-3585 was intravenously administered to rabbits at dose levels of 6250, 12500 or 25000 lU/kg for single dose toxicity study and at dose levels of 100, 500 or 2500 lU/kg/day for 4-week repeated dose toxicity study. In the acute toxicity study, dose up to 25000 lU/kg had no adverse effect on the behavior or body weight gain. Pathological examinations revealed no abnormal gross lesions related to DA-3585. In the subacute toxicity study, all animals survived until termination of treatment. DA-3585 had no influence on clinical signs, food and water intake or on body weight changes. Hematological examination showed increases in the number of RBC, hemoglobin contents and hematocrit values with a dose dependent manner in the animals treated with DA-3585. Histopathological examination revealed erythroid hyperplasia in the bone marrow and extramedullary hematopoiesis in the liver. The changes detected in the hematological and histopathological examination presumably represent exaggerated pharmacological effects of erythropoietin. The NOAEL (no-observed-adverse-effect-level) of DA-3585 was estimated to be 100 lU/kg/ day under this study condition.

A survey was performed on the outbreak of listeriosis in a Korean native goat in Animal Breeding Station of Gyeongsang National University, Chinju, Korea. Clinical signs in the affected goat were fever, dullness, inappetence, nasal discharge, slobbering, dysphagia, circling, incoordination, recumbency, unilateral facial paralysis, torticollis, dyspnea, spasmodic paddling movement of the limbs and death at 6 days after onset. No significant gross lesions were seen. The histopathological lesions were consisted of perivascular edema and cuffs by round cells and microabscess with infiltration of neutrophils, lymphocytes and macrophages in the cerebrum. Gram-positive organism was observed in the microabscess lesions. Listeria monocytogenes was isolated exclusively from the brain tissue by cultural examination and the lesions induced by experimental infection with the isolate were characterized by severe conjunctivitis in rabbit and hepatic necrotic foci in mouse. This seems to be the first report of listeriosis in Korean native goat.

We know that the Hurst Exponent (HE) is a real number in [0, 1] which denotes randomness of time series. in this research, we suggest non-linear analysis of human biological signals through HE. The feasibility of human biological signals using inductive incitement provides Some diagnosis for active treatment. In our experiment, we measured the heartbeat through the MCG, 29 healthy and 34 abnormal subjects ostensibly. The raw data of acupuncture incitement are supported by opinions of gross examination and pathological diagnosis. The mean values of HE are 0.345, 0.755 and 0.805 for the periods of before, during and after acupuncture treatment, respectively in case of abnormal subjects. On the other hand, the mean values, 0.808, 0.797 and 0.785 are for normal cases, correspondingly. From this data, we show that HE is very significant in abnormal controls according to an acupuncture incitement, and the incitement effect is evidently extracted in abnormal subjects. But, in normal subjects, the incitement effect is meaningless.

Daily oral administration to Sprague Dawly rats for 4 weeks of DWP-301, at doses of 0, 500, 1000, 2000 mg/kg presented following results; 1) No animals died and there were no significant differences in general signs, body weight, food consumption, urinalysis haematological, biochemical, gross pathological and histopathological examination between control and treated rats. 2) Water consumption, pH-, protein- urobilinogen-, ketone-values in urine were significantly increased in the treated male and female rats. It is supposed that these differences in animals are a consistent feature of repeated overdosage with test suspensions. The results indicate that the non toxic dose of test compounds in rats is over 2000 mg/kg in this test system.

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.

A 9 year-old male Maltese with dysuria, pollakiuria, and stranguria was brought to the Veterinary Teaching Hospital, Chonnam National University. A right lateral abdominal radiograph was shown that 3 uroliths existed at the caudal aspect of the os penis and 5 uroliths existed in the passage of os penis. Uroliths were extracted by voiding urohydropropulsion and cystotomy in Maltese dog. The complication of cystotomy was hematuria, which might persist up to 2 days postoperatively but dysuria was not observed. So we applied voiding urohydropropulsion and cystotomy, and got a good prognosis. Gross examination of extracted uroliths were separated one from another but it was identified the same componet of calcium oxalate by stone quantitative analysis.

This study was performed to evaluate repeated-dose toxicities of STB-HO-BM in Sprague-Dawley rats. STB-HO-BM was administered orally to rats at dose levels of 0, 100, 300 and 1,000 mg/kg/day for 13 weeks. In recent study, there were no dose related changes in mortality, clinical signs, body weight changes, food and water consumption, opthalmoscopy, organ weights, urine analysis, hematological findings, and biochemical examination of all animals treated with STB-HO-BM. Gross and histopathological findings revealed no evidence of specific toxicity related to STB-HO-BM. These results suggest that the oral no observed adverse effect level (NOAEL) of STB-HO-BM may be over 1,000 mg/kg in rats.
