  • In acute pancreatitis group, all the dogs are showed increase of amylase and lipase after the 1st day of surgery, and amylase and lipase activity were significantly more increased than those of control group. The methemalbumin was increased significantly after the 2nd day of surgery in the acute pancreatitis group. In pancreatitis group, ultrasonographic findings included thickened duodenal wall and poorly circumscribed hyperechoic lesion of pancreatic mass after the 2nd day of surgery. And the lesion was exacerbated until the 4th day and reduced after the 6th day of surgery. To identify the lesion of pancreas, it is considered that transverse view is more useful Than sagittal view. Gross findings showed increase of pancreatic parenchymal consistency, surface nodule, and extensive pancreatic necrosis. Necrosis of peripancreatic fat tissue was also a prominent feature. The microscopic appearance of the pancreas was characterized by pancreatic acinar cell necrosis, hemorrhage, infiltration of the inflammatory cell and fat necrosis and saponification were also observed.

  • Avian reovirus (ARV) and fowl adenovirus (FAdV) were evaluated for pathogenicity in specific pathogen free (SPF) chickens. ARV was isolated from the broilers with history of malabsorption syndrome (MAS). FAdV was isolated from the layer breeders with inclusion body hepatitis and hydropericardium syndrome. Total 6 inoculated groups including 1 un-inoculated group were organized and inoculated with the ARV and/or FAdV by oral route. The minimal pathological lesions and lower viral gene detection rates were present in the ARV inoculated groups compared to those of FAdV or ARV/FAdV inoculated groups. Common gross lesions in the ARV inoculated group were distended intestine with foamy contents and in the FAdV group there were foamy cecal contents and hydropericardium among the evaluation methods such as gross and histological lesion, viral gene detection, body weight and serum chemistry, histopathological lesion score was reliable especially in the liver lesions such as hepatic necrosis and lymphocytic infiltration. However, we did not success to evaluate the synergetic effect of mixed infection of ARV and FAdV in this study. Therefore, we need further study to reproduce malabsorption syndrome of ARV infection using different viral agent such as rotavirus and using different dose of virus.

  • Porcine respiratory disease complex (PRDC) continues to be a significant economic problem to the swine industry. In order to elucidate the etiology of PRDC including porcine circovirus type 2 (PCV2), porcine reproductive and respiratory disease syndrome virus (PRRSV), swine influenza virus (SIV), Mycoplasma hyopneumoniae (MH), Pasteurella multocida (PM) and Actinobacillus pleuropneumoniae (APP) in Namwon, the 455 lung samples were randomly collected from slaughtered pigs, examined gross lesions indicative of respiratory disease of lung and classified the lung lesion according to the severity of lung lesions. Two hundred pigs lung tissues with pneumonic lesions were examined for pathogen by PCR. As a result, the numbers of pneumonic lesions were 357 (78.5%), mean pneumonic score ($mean{\pm}SD$) was $2.03{\pm}0.90$ and the highest gross lesion according to stages was 1 (11~20%). In detection of pathogens, PCV2, PRRSV, SIV, MH, APP and PM were positive in 76.5%, 5.0%, 6.0%, 9.0%, 4.5% and 6.0%, respectively and PCV2-MH was the most detected causative pathogens of PRDC in co-infection. In the serological test for PRRSV, PCV2, MH, APP2, APP5, HP and PM, showed high antibody positive rates 93% or more.

  • Objectives : The water extract of Sopung-tang (SPT) has been traditionally used in the treatment of acute stroke in Oriental Medicine. Pro-inflammatory cytokines play a critical role in the onset of post-ischemic inflammatory cascades. The present study was designed to investigate the effects of SPT on pro-inflammatory cytokine production in a photothrombotic ischemia mouse model. Methods : After SPT oral administration to the mice for five days, with using Rose Bengal and cold light, photothrombotic ischemia lesion was induced in stereotactically held male BALB/c mice. Also, results including, gross finding lesion size, histopathological finding changes, and inflammatory cytokine expression changes from the photothrombotic ischemia mouse model were observed. Results : The photothrombotic ischemia lesion was decreased by the oral injection of SPT. Also, SPT inhibited the expression of TNF-$\alpha$, IL-$1{\beta}$, IL-6, the active form of caspase-3 protease, and transglutaminase-2 in the photothrombotic ischemia lesion. Conclusions : These results suggest that SPT protects the ischemic death of brain cells through suppression of the production of anti-inflammatory cytokines and catalytic activation of caspase-3 protease in the photothrombotic ischemia mouse model.

  • Total 160 head of porcine kidneys were examined for gross and histopathological lesions and polymerase chain reaction (PCR) for porcine circovirus type 2 (PCV-2), porcine parvovirus (PPV), Leptospira species and porcine reproductive and respiratory syndrome virus (PRRSV). Grossly, 137 kidneys (85.6%) had lesions characterized by the presence of the scattered white foci. Microscopically, multifocal interstitial nephritis, which classified into 4 grades such as, no lesion (Score 0), mild lesion (Score 1), moderate lesion (Score 2) and severe chronic lesion (Score 3) with fibrosis, was observed in 159 cases (99.4%). The histopathologic mean score for multifocal interstitial nephritis was significantly different (P<0.05) between the cases of PCV-2 single infection and the cases of co-infection with PCV-2 and PPV. According to PCR evaluation, PCV-2 were detected in 73.8% (118 cases), PPV were in 66.9% (107 cases), however Leptospira spp. and PRRSV were negative in all kidneys. Both PCV-2 and PPV were detected in 52.5% (84 cases). In 84 cases co-infected with PCV-2 and PPV, the occurrence of lymphoid follicle and vasculitis were observed as 65.5% (55 cases) and 26.2% (22 cases), respectively. These results revealed that PCV-2 and PPV were major infectious agents for interstitial nephritis in slaughtered pigs, Jeju. And the histopathologic lesions of multifocal interstitial nephritis were more severe in the case co-infected with PCV-2 and PPV.

  • Purpose : Banhasasim-tang (BHSST) has been applied for treating the symptom of gastric stuffiness, which is similar to dyspepsia. The object of this study was to observe the healing effect of BHSST on the indomethacin (IND)-induced gastric ulcer in rats. Methods : Three different dosages of BHSST (400, 200 and 100 mg/kg) were orally administered 30 min before IND treatment; 6 hrs after IND treatment, the changes on the gross lesion scores, fundic histopathology, myeloperoxidase (MPO) activity, lipid peroxidation and antioxidant defense system (glutathione contents, catalase (CAT) and superoxide dismutase (SOD) activities) were observed, and compared with the activity of the synthetic anti-ulcer drug, a representative proton pump inhibitor omeprazole (OME) 10 mg/kg. Results : All three different dosages of BHSST treatment in the IND-induced gastric ulcer rats, significant and dose dependent decreased gastric damages - hemorrhagic gross lesions, gastric mucosa MPO levels and histopathological gastric ulcerative lesions - were detected as compared with the IND treated control rats. BHSST also strengthened the antioxidant defense systems - decreased the level of lipid peroxidation and CAT activity but increased the level of GSH and SOD activity, and BHSST 200 mg/kg showed similar anti-ulcerative effect as compared with OME 10 mg/kg. Conclusions : The results obtained in this study suggest that BHSST has favorable effects against IND-induced gastric damages, through significant and dose-dependent decreasing gastric damages and the strengthening of the body's antioxidant defense systems with direct anti-inflammatory effects.

  • Respiratory diseases are common in swine industry and have great economic importance. Respiratory disorders cause substantial losses to the swine industry. Losses associated with respiratory disease vary considerably between herds and seasons. In a survey was carry out to investigate the lesion of red internal organs in slaughtered pigs and provided assistant data which are useful for each farm. From november 2012 to december 2013, 1,680 pigs out of 84 farms were sampled in Jeonbuk province. Gross lesions such as swine enzootic pneumonia (SEP), pleuritis, pleuropneumonia, pericarditis, liver milk spot were examined for the pigs. Overall prevalence of SEP was 55.7%. According to season, the incidence occurred higher in fall than winter, spring, and summer. The mean SEP score was 0.91, the highest incidence occurred in fall. The prevalence of pleuropneumonia, pleuritis, pericarditis, and milk spot was 36.4%, 49.7%, 2.3%, and 8.8%, respectively. The positive rate of PRRS and PCV2 was 2.9% and 70.0% by PCR analysis.

  • 색소 융모 결절성 활액막염(pigmented villonodular synovitis, PVNS)은 병인이 밝혀지지 않은 증식성 질환으로, 병변의 범위에 따라 국소형과 미만형으로 분류되며, 조직학적으로 양성이지만 파괴적인 성향을 보이므로 연골의 파괴나 주위 조직으로 광범위한 침윤이 가능한 질환이다. 활액막 절제술이 일차적인 치료방법이지만 미만형인 경우에는 주위 조직을 침윤하는 성향 때문에 재발률이 높다. 재발이 반복된 후에는 수술적 절제가 어려워져서 병변부위의 절단이 필요하게 되므로, 광범위한 병변인 경우, 수술이 용이하지 않은 경우, 또는 불완전 절제가 시행된 경우 등에서 방사선치료를 시행하여 재발을 방지할 수 있다고 보고되고 있다. 저자들은 무릎관절의 미만형 색소 융모 결절성 활액막염으로 관절경을 이용한 육안적 활액막 전 절제술 후 방사선치료를 시행한 2예를 경험하였기에 문헌고찰과 함께 보고하고자 한다.
