Korean Journal of Veterinary Research.2012;52(4):285-288.

Salmonella I 4,[5],12:i:- was a monophasic variant of Salmonella (S.) Typhimurium and notorious for re-emerging candidate which would replace S. Typhimurium DT104 for antibiotic resistance. Recently, isolation rate was increased on human and industrial animals but there was no case in domestic animals but human in Korea. This was first isolation case from domestic animals in Korea. The five isolates from feces of duck (n = 3), chicken (n = 1), and wild bird (n = 1) showed antibiotic resistance against cephems and aminoglycosides. These means that the spread of emerging bacterial pathogens to domestic animals and the need of systemic management for Salmonella I 4,[5],12:i:-.

Korean Journal of Veterinary Research.2012;52(4):281-283.

An 8-year-old female, German Shepherd dog was presented with history of dyspnea and seizure. One Year Previously a lumpectomy had been performed for surgical resection of mammary mass. In serum chemistry, severe hypoglycemia and elevation of aspartate aminitransferase and creatine kinase were shown. In thoracic radiography, there were variable sized nodules in the overall lung field. On computed tomography examination, the mass was shown in left longissimus lumborum muscle. Histopathological examination revealed adenocarcinoma derived from the mammary gland. Muscular metastasis of mammary gland tumor is uncommon. This is a rare observation and could easily be overlooked or misinterpreted.

Korean Journal of Veterinary Research.2012;52(4):275-280.

The kiwi (Actinidia deliciosa) is well known to contain anti-oxidants. In this study, we investigated the anti-oxidant effects of kiwi extract on carbon tetrachloride (CCl4) induced liver injury in BALB/c mice. The radical scavenging effect of 80% methanol extract of Halla-Gold kiwi was observed. For the animal study, mice were randomly divided into four groups: normal group, CCl4-induced model group, kiwi extract administered group, and silymarin treated group. The kiwi extract was provided daily for 10 days. At the 24 h after last administration, CCl4 was injected. The kiwi extract showed strong inhibitory effect of DPPH radicals and superoxide scavenging. In animal study, administration of CCl4 resulted in significantly elevated plasma levels of ALT and AST but they decreased in kiwi-extract pretreated group. Anti-oxidant enzymes such as GSH-px and GSH-rd were restored in the kiwi extract treatment group. Histopathological degeneration was also prevented in the kiwi extract treated group compared with of the control group, which exhibited CCl4-induced hepatotoxicity. On the basis of the obtained results, it can be concluded that kiwi extract showed protective effects, not only as anti-oxidant effects, but also in the protection of hepatotoxicity in CCl4-intoxicated mice.

Two Korean black goat (approx. 2 and 3 years old) showing diarrhea and chronic weight loss were submitted to Animal and Plant Quarantine Agency. At necropsy, there were thickening of small intestine and enlargement of mesenteric lymph nodes. Microscopically, they had granulomatous enteritis in the small and large intestine and granulomatous lymphadenitis. By polymerase chain reaction (PCR) and acid fast stain, strong positive reaction and acid-fast rod bacteria were detected. According to the result of histopathology and PCR, we confirmed this case as Johne's disease. As far as we know, this is the first report of Johne's disease in Korean black goat.

Korean Journal of Veterinary Research.2013;53(4):269-271.

Here, we report the poisoning case of 10 cows. Several distinct clinical signs such as convulsion, excessive salivation, circling, lateral recumbency, and death were observed. Necropsy and histopathological examination did not reveal any significant abnormal findings. Moreover, no bacteria or viruses were detected in tissue, blood, and feeding food. However, endosulfan was detected from the stomach contents and microbials. Our results strongly suggest that death of cows may be closely associated with endosulfan poisoning.

Korean Journal of Veterinary Research.2013;53(4):265-267.

A 3-month-old, intact male French bulldog was suspected of deafness. The dog was irresponsive to environmental noises generated out of sight, but normal responses were noted for visual stimuli. No abnormalities were observed on the neurological, otoscopic, radiographic, and blood examinations. To diagnose the apparent deafness, brainstem auditory evoked potential (BAEP) was recorded in the presented dog together with a normal dog. While the BAEP from the control dog showed a normal wave consisting of 5 peaks, absence of all peaks was noted in the suspected deaf dog. Therefore the dog was definitively diagnosed as bilaterally congenital sensorineural deafness.

Korean Journal of Veterinary Research.2013;53(4):263-264.

A 6 year-old, spayed female, Maltese dog was presented with precordial thrill and mild coughing. Thoracic auscultation revealed a grade V/VI systolic murmur with maximal intensity over the left apex characterized by musical murmur. Echocardiography revealed mild myxomatous degeneration of mitral valve and ruptured chordae tendineae. Musical murmur was produced due to the vibration of ruptured piece of chordae tendineae along with regurgitant flow. After treatment with furosemide and ramipril, clinical signs resolved and precordial thrill reduced. This case report describes typical clinical signs and phonocardiogram of musical murmur in a dog with acute chordae tendineae rupture.

Korean Journal of Veterinary Research.2013;53(4):257-261.

This study evaluated two different surgical techniques for the treatment of palmar annular ligament desmitis (PAL) in horses. The group 1 (G1) consisted of 11 Thoroughbred submitted to desmotomy, and G2 of 22 horses that underwent PAL desmectomy. There was no statistically significant difference between mean palmar annular ligament thickness in both groups evaluated (p = 0.800). In this study, the horses of G1 had 12 times more chance to return to physical activity, when compared to animals of G2 (p = 0.033; O.R. = 12.0; C.I.95% = 1,142 - 126,122). Desmectomy was more efficient in promoting the resolution of the injury and the return to sports activity.

Korean Journal of Veterinary Research.2013;53(4):253-256.

An 8-year-old, castrated male, Schnauzer dog was presented for evaluation of gradually worsening erythematous papules. Physical examination revealed multiple erythematous papules having a firm, gritty texture located in bilateral ears, dorsal midline, perianal and inguinal area. Skin biopsy revealed aberrant structure, characterized by atrophic epidermal-dermal layer structure with granular materials which was presumed as calcinosis cutis secondary to iatrognic hyperadrenocotricism. By initiating minocycline for 14 days, there was reduction in size, number of calcium deposit with remarkably decreased erythema. This case report presents the clinical trial of minocycline as a potential agent in treating dogs with calcinosis cutis.

Pathologic studies in lymph nodes of pigs infected with porcine circovirus type 2, porcine reproductive and respiratory syndrome virus.

Ji Youl JUNG ; Jae Hoon KIM

Korean Journal of Veterinary Research.2013;53(4):245-251.

Porcine circovirus type 2 (PCV2) and porcine reproductive and respiratory syndrome virus (PRRSV) have been suspected to have immunosuppressive effects on pigs. To investigate the correlation between these virus infection and the lesions of lymph nodes including sub-mandibular and inguinal lymph node, 44 pigs (PCV2 single, n = 14; PRRSV single, n = 10; PCV2/PRRSV, n = 14; negative control, n = 6) were examined by histopathology and immunohistochemistry. Histopathologically, granulomatous lymphadenitis characterized by lymphoid depletion with histiocytic cells infiltration was observed in PCV-2 single and PCV-2/PRRSV group. Immunohistochemically, there were significant reduction of B and T lymphocytes in lymph nodes of these groups, while the number of macrophages was increased. In only PRRSV infected group, germinal center hypertrophy and lymphoid necrosis were observed. Immunohistochemically, the number of CD3+ T lymphocytes was slightly increased. Severe lymphocytic depletion in PCV-2 infection-related lymph nodes might be associated with producing immunocompromised state in pig. Comparing with PCV-2 infected group, PRRSV produced minor effects on the changes in immune cell population in the lymph nodes of pigs. PRRSV may increase susceptibility of the disease in pigs by disruption of the first defense lines in target organs, such as the alveolar macrophages in lungs.
