  • The Korea chinese chives are a major edible vegetable and they are traditionally been used as a folk medicine. However recently studies on the Allium tuberosum are mainly on the morphological property and the chemical constituent. There are no reports concerning hematological changes in dogs administrated ethyl acetate extracts of Korea chinese chive. This experiment was conducted to investigate the hematological changes in dogs administrated ethyl acetate extracts of the Korea chinese chives($5m{\ell}/mg$) for 6 days. During administration blood samples were collected at 3h, 6h, 12h and then on daily basis until day 6. Blood samples were analyzed red blood cell(RBC), packed cell volume(PCV), hemoglobin concentration(Hb), mean corpuscular volume(MCV), mean corpuscularl hemoglobin concentration(MCHC), reduced glutathion(GSH), and met-hemoglobin concentration. The RBC count was significantly(p<0.01, p<0.05) decreased during experimental periods. Packed cell volume, hemoglobin concentration were not showed significantly difference during experimental periods. The MCV was significantly(p<0.01, p<0.05) increased from 3 hours after administration to day 4. The MCHC was significantly(p<0.05)decreased on day 6. GSH concentration was not showed significant difference during experimental periods and the met-hemoglobin concentration was significantly(p<0.05) increased on day 3.

  • This is a case report on the occurrence of caprine arthritis-encephalitis (CAE) disease among dairy goats in a local farm located in Yeongdong-gun, Chungbuk. Previously, it was reported that the farm experienced intermittent deaths numbering 15 of the 97 goats raised for 5 months. Most of the goats less than 6 months of age were suffering from ataxia and posterior paresis, body tremor and abnormal head posterior. Affected animals frequently had stunted growth and had a rough coat. Goats more than 6 months of age were affected with an insidious, chronic arthritis characterized by articular swelling ('big knee') of the carpal, hock, and stifle joints. Necropsy revealed severely swollen mesenteric lymph nodes, under- flow of 2-3ml synovial fluid in the articular space and fibrous proliferation of synovial membrane. Histopathological examination showed perivascular accumulations of mononuclear inflammatory cells in the white matter of the brain, proliferative synovitis characterized by villous hypertrophy, synovial cell hyperplasia and infiltration by mononuclear inflammatory cells. Pulmonary lesions consists of patchy interstitial pneumonia with hyperplasia of lymphoid tissues and an extensive mononuclear inflammatory cell infiltration into the alveolar septa. Confirmation by nested PCR involves amplification of a 296 bp (lst PCR) and 184 bp (2nd PCR) fragments corresponding to the gag region of the CAE virus. This is the first time CAE has been reported in a local farm in Korea and emphasizes the importances of developing preventive measures against CAE.

  • Porcine proliferative enteritis (PPE) is a transmissible gastroenteric disease caused by Lawsonia intracellularis. Clinically, PPE causes hemorrhagic diarrhea and sometimes death in growing pigs, but when the disease progresses to a chronic phase, the infected pig no longer displays significant symptoms. The purpose of the present studies were carried out to determine L. intracellularis in the pig farms and slaughter house, in Gyeongnam area. A survey of proliferative enteritis in pig was conducted using polymerase chain reaction (PCR) testing method, total 1,495 samples. PCR products showed a specific band at the 210bp, 329bp in the specimens of feces and mucosal scraping. Of 420 fecal specimens, 113 (26.9%) were identified as positive to PPE. Of 1,075 mucosal scraping specimens, 109 (10.1%) were identified as positive to PPE. Of total 1,495 specimens, 222 (14.8%) were identified as positive to PPE.

  • This study was attempted to survey the prevalence of heartworm infection among 253 dogs (male 167, female 86) on the 16 breeding farms in southern Gyeongnam area in May to December 2007. The results obtained from this experiment were summarized as follows; Fifty seven (22.5%) of the 253 examined dogs were heartworms-antigen positive, while twenty five dogs were Microfilaria positive by the modified Knott's method. The regional infection rates were of 25% in Tongyeong and 21% in Goseong, and on the breeding environment aspects, infection rates were lower in rural area than urban area farms. The infection rates were higher in female (26/86, 30.2%) than male dog (31/167, 18.6%). The infection rates by breeding size of farms were 31% (11/35) at <20 head, 26%(35/135) at 20~50 head and 13% (11/82) at >50 head. The infection rates of heartworm in examined dogs at the age of <2, 2~4 and >5 were 10.7% (8/75), 26% (40/154) and 37.5% (9/24), respectively. In the microfillaria-infected 25 dogs, identified Dirofilaria immitis of 21 (84%) using PCR. The dogs infected with heartworm showed the increased number of eosinophil.

  • Mycobacterium avium subsp. paratuberculosis is the pathogen of paratuberculosis called Johne's disease. Johne's disease is hardly eliminated because of its long latent period and continuous dissemination, so it is found in ruminants worldwide and can cause substantial economic losses in cattle. It has been reported in many studies on the distribution of Johne's disease in some provinces of Korea that not many, but noticeable numbers of infected cows have been detected since the first detection in 1984. The aims of this study was to investigate the prevalence of Johne's disease obtained from slaughtered cattle in central area of Gyeongnam province, Korea. In this study, the ELISA serum antibody test and PCR were employed on a total of 240 blood and ileac substrate samples from slaughtered cattle in two slaughtering and wholesale centers in Gyeongsangnam-do Livestock Veterinary Research Institute Central Branch. Out of the entire 240 blood samples, three (1.3%) were positive by ELISA, while five (2.1%) were suspected cattle. But ileac substrate samples, eight (3.3%) were positive by PCR. By breeds, positive rates of ELISA and PCR in Korean native cattle were 1.3% and 3.5%, respectively, but no positive cows were found in dairy cattle. By provinces, sero-positive rates of Gyeongnam and Gyeongbuk were 1.6% and 1.3%, respectively. And PCR positive rates of Gyeongnam, Gyeongbuk and other provinces were 2.4%, 5.0% and 2.8%, respectively. These results indicate that it requires the nationwide monitoring test and measure to deal with subclinically infected slaughtering cows.

  • It's introduced a BLA(Branch Loop Antenna) that is modified from conventional loop, and verified antenna performances for applying to mobile handset. Branch elements are added to a rectangular loop, and low resonance is obtained by the length of the branch line. When resonance frequency of a single loop is 2.5GHz, BLA had near 900 MHz under the same antenna size. Multiple resonances are established by the locations of branch connection and their lengths. By the implementation and measurement for the dual band BLA, it's showed 75MHz -10dB bandwidth and -3.03~-1.46dBi average gains with 49.73~71.39% efficiencies at GSM900 band, and 90MHz -6dB bandwidth and -8.14~-2.17dBi average gains with 15.34~60.62% efficiencies at DCS1900 band. And H-plane radiation patterns were omni-directional. These performances are good for the mobile handset antenna.

  • Background: Incidence and mortality rates for cancer have increased dramatically in the recent 30 years in Taiwan. However, not all patients receive treatment. Treatment refusal might impair patient survival and life quality. In order to improve this situation, we proposed this study to evaluate factors that are related to refusal of treatment in cancer patients via a cancer case manager system. Materials and Methods: This study analysed data from a case management system during the period from 2010 to 2012 at a medical center in Northern Taiwan. We enrolled a total of 14,974 patients who were diagnosed with cancer. Using the PRECEDE Model as a framework, we conducted logistic regression analysis to identify independent variables that are significantly associated with refusal of therapy in cancer patients. A multivariate logistic regression model was also applied to estimate adjusted the odds ratios (ORs) with 95% confidence intervals (95%CI). Results: A total of 253 patients (1.69%) refused treatment. The multivariate logistic regression result showed that the high risk factors for refusal of treatment in cancer patient included: concerns about adverse effects (p<0.001), poor performance(p<0.001), changes in medical condition (p<0.001), timing of case manager contact (p=.026), the methods by which case manager contact patients (p<0.001) and the frequency that case managers contact patients (${\geq}10times$) (p=0.016). Conclusions: Cancer patients who refuse treatment have poor survival. The present study provides evidence of factors that are related to refusal of therapy and might be helpful for further application and improvement of cancer care.

  • Objectives : The purpose of this study is to investigate the effect of Chuna treatment for neck pain patients caused by traffic accident. Methods : 64 patients were divided into two groups, experimental group and control group, of 32 patients each. Control group was treated with general korean medical treatment three times per week for 2 weeks. Experimental group was treated with Chuna treatment and general korean medical treatment three times per week for 2 weeks. We evaluated the treatment effect of each group with the visual analog scale(VAS) and neck disability index(NDI). Results : 1. In both two groups, VAS were decreased significantly in statistics after treatment. 2. In both two groups, NDI were decreased significantly in statistics after treatment. 3. There were significant reduction of the VAS in experimental group than control group, but, there were not significant reduction of the NDI in experimental group than control group. Conclusions : We suggest that Chuna treatment could be recommended as a useful therapy to neck pain patients caused by traffic accident.

  • This study was investigated to diagnose pathogenic organisms of atrophic piglets in northern area of the Gyeongnam province, Korea. Samples such as feces, blood and necropsy specimens of 42 atrophic piglets (${\leq}10$ weeks old) were taken from May to December 2013 for this survey. Samples were examined by reverse transcriptase-polymerase chain reaction (RT-PCR) assay and bacteria isolation for detection of pathogenic agents. 93 pathogens were isolated from 42 samples can be classified into ll groups. We identified bacterial agents in 56 cases (60.2%) and viral agents in 31 cases (33.3%). However, 6 cases (6.5%) were undetected. Among these pathogens, the most prevalent disease were porcine reproductive and respiratory syndrome (PRRS) in 22 cases (23.7%). The major diseases were Colibacillosis in 15 cases (16.1%), Glasser's disease in 12 cases (12.9%), and porcine epidemic disease (PED) in 9 cases (9.7%). Mixed infections were accounted for 77.8% of atrophic piglets. In particular, the rate of mixed infections with PRRS virus showed the highest frequency (71.4%). In addition, there is a seasonal variation. Viral pathogens were dominantly detected in winter, but in the rest of the season bacterial agents were mainly detected. Gastrointestinal diseases occurred mainly in the pre-weaning piglets, the respiratory diseases and wasting diseases occurred mainly in the post-weaning piglets.
