This study was performed to evaluate antimicrobial resistance of food-borne pathogens isolated from retail meat in Korea. A total of 157 samples of beef, pork, and chicken were collected and analyzed for E. coli, Salmonella, Campylobacter. Resistances to tetracycline were declined in accord with reduced usage of tetracycline in live stock production. E. coli stains from chicken meat had higher multi-drug resistance ratio than strains from other meat. One extended spectrum beta lactamase (ESBL) producing E. coli and two ESBL producing Salmonella were identified in this study. ESBL producing Salmonella strains were confirmed to carry CTX-M-1 type genes.

부비장은 정상인의 약 10%에서 발견되고 약 16%에서 췌장에서 발견되는 것으로 알려져 있다. 그러나 췌장 내의 부비장에서 발생한 유표피 낭종은 극히 드물고 특이적 방사선 소견이 없어 진단하기 매우 어려워 췌장의 낭성 종양으로 오진하기 쉽다. 저자들은 우연히 발견된 췌장 미부의 낭성 종괴에 췌장 낭성 종양 의심하에 원위부 췌장절제술을 시행하였으나 수술 후 병리학적인 검사상 췌장 내 부비장에서 발생한 유표 피 낭종으로 진단된 증례를 2예를 경험하였기에 문헌고찰 과 함께 보고하는 바이다. 췌장 내 부비장의 유표피 낭종은 영상학적인 검사나 임상양상을 통해서는 다른 췌장의 낭성 종양과 쉽게 구분할 수가 없으며 따라서 췌장 낭성 종양에 대한 감별진단으로 췌장 내 부비장의 유표피 낭종의 가능성도 고려가 필요하겠다.

New balloon flower (Platycodon grandiflorum) variety, ‘Jangbaek’, had been developed by pureline selection from some native cultivars collected in Milyang by the medicinal crops research team of the National Yeongnam Agricultural Experiment Station at 200

A new soybean variety “Geomjeongkong 3” was released by the National Crop Experiment Station, RDA, in 2001. This variety was derived from the cross between Shinano-kuro and SNU78010, the elite breeding line with large seed, in the summer season, 1990. The
