A 1-week-old, male Korean native calf with acute clinical signs of depression, mild diarrhea, ataxia, recumbency and tremor was referred to Chonbuk Veterinary Medical Center of Chonbuk National University. Vision loss and cornea edema were also observed on physical examination. The patient had been deteriorated with nystagumus, strabisumus and opisthtonus. Blood cell count test and blood biochemistry test revealed remarkable leukocytosis, and hypoalbuminemia and increased blood urea nitrogen. No remarkable findings were observed on radiography. On magnetic resonance imaging study, there were enlarge lateral, third, and forth ventricles. The cortical grey and subcortical white matter of left temporal lobe showed hypointense on T1-weighted images and hyperintense on T2-weighted images, and slightly enhanced on contrast-enhanced T1-weighted images. Escherichia coli strain was identified from cerebrospinal fluid sample. Palliative treatment was attempted but the neonatal calve was expired three days after admission. Severe multifocal fibrino-suppurative meningitis with Escherichia coli infection was confirmed histopathologically.

Colibacillosis in pigs remain a major swine industry bruden worldwide. Although some progress has been made in treating collibacillosis in pigs by using biosecurity and antimicrobials, it still remain a considerable problem. The use of host-specific bateriophages as a biocontrol is one possible alternative. The purpose of this study was to evaluate the effect of bacteriophage against enterotoxigenic Escherichia coli (ETEC) K88 infection in piglets. Twenty-eight piglets were randomly divided into four groups and each group was allocated with 7 pigs. Group B, C and D were inoculated with 5 ml of ETEC K88 ($1{\times}10^8$ CFU/ml) per head of piglet via oral. Group C and D were fed with bacteriophages (Group C, $1.0{\times}10^6$ PFU/g; Group D, $1.0{\times}10^8$ PFU/g; CJ CheilJedang Corp., Korea) orally as treatment. In piglets administrated bacteriophages and challenged with ETEC K88 (Group C and D), Clinical signs and the growth performance were improved and antibody titers were maintained low level compared with piglets challenged with ETEC K88 (Group B, P<0.05). Group B were shown high pH in the alimentary tracts compared with other piglets (P<0.05). In quantitative analysis by real-time PCR, the results of Group C and D were lower than those Group B in faecal and intestinal samples (P<0.05). Severe villus atrophy and crypt hyperplasia were observed in Group B consequently V/C ratio increased, compared with other piglets. These results indicate that feeding with bacteriophage has effect to prevent ETEC K88 infection in piglets and suggest that use of bacteriophage can be considered a valid antibiotic alternative.

Two dogs referred to Veterinary Medical Center, Chungbuk National University diagnosed as multiple extrahepatic portosystemic shunt were reported. The first dog was a 20-month-old, 8 kg, male Cocker spaniel with history of peritoneal effusion, diarrhea, anorexia and stunted growth. The second dog was a 3-year-old, 13.4 kg, male Jindo with a history of severe depression. Hematologic examination of first dog revealed mild microcytosis and nonregenerative anemia. All of 2 cases, serum chemical values showed increase of serum ammonia, ALP, r-GTP and glucose. In survey radiography, microhepatia was apparent. In the color Doppler ultrasonographic examination, the first dog revealed a dilated tortuous vein communicating with caudal vena cava was observed near the left kidney and the second dog revealed numerous shunting vessels ventral to L5 and L6. Transcolonic portal scintigraphy of the first dog confirmed the presence of portosystemic shunt. In intraoperative jejunoportography, the first dog showed single congenital extrahepatic portosystemic shunt and multiple acquired extrahepatic portosystemic shunts. The second dog showed multiple acquired extrahepatic portosystemic shunts. In these dogs, the presence of congenital and acquried portosystemic shunts and histopathologic findings were considered to represent a combination of multiple extrahepatic portosystemic shunts and noncirrhotic portal hypertension or portal vein hypoplasia.

An epidemic outbreak of food poisoning due to enterohemorrhagic Escherichia coli(EHEC) occurred throughout Korea from May to September, 2003. Patients infected via contaminated school lunch foods were found mainly in Seoul and Gyeonggi province. As a result of this food poisoning, 36 patients were diagnosed as hemolytic uremic syndrome(HUS) up to mid-September, 2003 and five of them visited our hospital. Before the outbreak this year, we had experienced only 23 cases of HUS, including diarrhea associated (D+) and atypical (D-) forms, for the last 14 years, and there had been no case with pancreatic enzyme elevation. Unlike the past HUS cases, those of this year presented with severe abdominal pain and spiking elevation of pancreatic enzyme levels in 2 cases. We report 2 cases of transient pancreatitis combined with HUS in children during the epidemic outbreak in 2003 with a brief review of related literatures.

We examined total body irradiation (TBI)-induced effects by complete blood count (CBC) and fluorescence-activated cell sorter analysis (FACS) in the piglet following radiation irritation. A CBC included red blood cell count, white blood cell count, and platelet cell count. Four piglets were examined in this study and each piglet was divided by irradiation dose, two piglets with 4 Gy, two with 6 Gy, one with 8 Gy. All piglets showed leukopenia, thrombocytopenia after irradiation. In 6 and 8 Gy group, three piglets showed severe hemostatic disorder and gastrointestinal disorder suchas diarrhea and anorexia, and they died between 10 and 15 days after radiation irritation. In 4 Gy, two piglets showed no clinical sign after radiation injury, but persistent leukopenia was shown in blood examination. We suggest that a single TBI dose less than 6 Gy is adequate for conditioning piglet for bone marrow transplantation.

The present study aimed to investigate the comparative evaluation of pharmacological efficacy between sulfasalazine alone and combination with herbal medicine on dextran sodium sulfate (DSS)-induced UC in mice. Balb/c mice received 5% DSS in drinking water for 7 days to induce colitis. Animals were divided into five groups (n = 9): group I-normal group, group II-DSS control group, group III-DSS + sulfasalazine (30 mg/kg), group IV-DSS + sulfasalazine (60 mg/kg), group V-DSS + sulfasalazine (30 mg/kg) + Radish Extract mixture (30 mg /kg) (SRE). DSS-treated mice developed symptoms similar to those of human UC, such as severe bloody diarrhea and weight loss. SRE supplementation, as well as sulfasalazine, suppressed colonic length and mucosal inflammatory infiltration. In addition, SRE treatment significantly reduced the expression of pro-inflammatory signaling molecules through suppression both MAPK) and nuclear factor-kappa B (NF-${\kappa}B$) signaling pathways, and prevented the apoptosis of colon. Moreover, SRE administration significantly led to the up-regulation of anti-oxidant enzyme including SOD and Catalase. This is the first report that Radish extract mixture combined with sulfasalazine protects against experimental UC via the inhibition of both inflammation and apoptosis, very similar to the standard-of-care sulfasalazin.

Objectives: Rotavirus is one of the main causes of severe diarrhea in children under five. Two types of rotavirus vaccines [$Rotarix^{(R)}$ (RV1) and $Rotateq^{(R)}$ (RV5)] have been introduced and its administration was optional in South Korea. A systematic review (SR) on economic evaluation (EE) of RV was conducted to examine whether the introduction of rotavirus vaccine to national vaccine program (NIP) is cost-effective. Methods: Previous SR studies of EE for RV were searched in August 2017 through databases such as MEDLINE and EMBASE. Additional search was performed to include literatures published after or unincluded in the previous SR studies. Among the 11 SR studies identified, 2 studies were reviewed via inclusion/exclusion criteria. A previous SR study including 104 original articles was selected by A MeaSurement Tool to Assess systematic Reviews. Among the 36 original articles identified through additional search, 10 were selected, resulting in 114 studies included in our analysis. Results: RV1-only, RV5-only, and evaluating-both studies account for about 44%, 22%, and 33%, respectively. Among RV1-only, RV5-only, or evaluating-both studies, 90%, 64%, or 68% of the studies concluded RV as being cost-effective, respectively. RV5-only studies were usually executed in high-income countries (68%), whereas RV1-only studies were executed mostly in lower (32%) and upper (26%) middle-income countries. When classifying studies by their funding sources, RV1-only studies (82%; 28 of 34 studies specifying funding sources) were chiefly supported by non-profit organization, and 100% of these studies were concluded as being cost-effective. RV5-only studies were mostly supported by profit organization (68%; 13 of 19 studies specifying sources), and 92% of these studies concluded as being cost-effective. Conclusion: By reviewing global EE studies for RV, we have learned that about 70% of these studies was shown to be cost-effective and RV1 appeared to be more cost-effective than RV5.

We analyzed the demand of competent authorities requiring adequate technical information for initial investigation of chemical accidents. Reflecting technical reports on chemical accident response by environmental agencies in the U.S. and Canada, we presented information on environmental diffusion and toxic effects available for the first chemical accident response. Hydrogen fluoride may have the risk potential to corrode metals and cause serious burns and eye damages. In case of inhalation or intake, it could have severe health effects. The substance itself is inflammable, but once heated, it decomposes producing corrosive and toxic fume. In case of contact with water, it can produce toxic, corrosive, flammable or explosive gases and its solution, a strong acid, may react fiercely with a base. In case of hydrogen fluoride leak, the preventive measures are to decrease steam generation in exposed sites, prevent the transfer of vapor cloud and promptly respond using inflammable substances including calcium carbonate, sodium bicarbonate, ground limestone, dried soil, dry sand, vermiculite, fly ash and powder cement. The method for fire fighting is to suppress fire with manless hose stanchions or monitor nozzles by wearing the whole body protective clothing equipped with over-pressure self-contained breathing apparatus from distance. In case of transport accident accompanied with fire, evacuation distance is 1,600m radius. In cae of fire, fire suppression needs to be performed using dry chemicals, CO₂, water spray, water fog, and alcohol-resistance foam, etc. The major symptoms by exposure route are dyspnoea, bronchitis, chemical pneumonia and pulmonary edema for respiration, skin laceration, dermatitis, burn, frostbite and erythema for eyes, and nausea, diarrhea, stomachache, and tissue destruction for digestive organs. In atmosphere, its persistency is low, and its bioaccumulation in aquatic organism is also low.

Purpose : A wide, epidemic outbreak of M. pneumoniae pneumonia occurred throughout Korea in late 2003. Compared with previous years, the 2003 outbreak resulted in more severe cases and in an increased incidence of extrapulmonary symptoms and/or complications. We compared the clinical characteristics for M. pneumoniae pneumonia of 2003 to those of the past years. Methods : One hundred six children diagnosed with M. pneumoniae pneumonia by serologic tests at Bundang Cha General Hospital between Aug 2003 to April 2004 were enrolled. Medical records were reviewed retrospectively, for clinical, laboratory and radiological aspect as well as complications. The pleural effusions of 3 patients who underwent thoracentesis were also analyzed. Results : The duration of fever, cough, rhinorrhea, and sore throat was $8.2{\pm}4.7$, $22.1{\pm}4.8$, $8.4{\pm}2.1$, $4.3{\pm}1.2$ days, respectively. The incidence (percentage) and duration of abdominal pain, vomiting, diarrhea, headache, skin rash, arthralgia was $5.1{\pm}2.5$ (21.9%), $3.4{\pm}2.1$ (17.1%), $4.3{\pm}1.8$ (16.2%), $3.5{\pm}2.1$ (14.4%), $5.5{\pm}0.7$ (5.9%) and $4.6{\pm}1.3$ days (4.9%), respectively. The mean duration of admission and treatment were $7.4{\pm}4.3$ days and $21.6{\pm}11.1$ days. Higher values of CRP and ESR on admission were positively correlated with the duration of fever and length of admission. The findings of pleural effusion were similar to those seen in TB pleurisy. Complications, including myocarditis (2 cases), arthritis (3 cases), vasculitis (5 cases), asthma (3 cases), ARDS (1 case), and DIC (2 cases) were observed in 14.1% of patients. Conclusion : We found a number of characteristics of M. pneumoniae pneumonia among cases from late 2003 that were different from those of previous years. This outbreak resulted in more severe cases and in an increased incidence of extrapulmonary symptoms and/or complications. A multicenter study is needed to verify the changes in clinical characteristics observed during the 2003 outbreak from previous ones.
