Vibrio fluvialis는 바닷물 또는 해산물에서 발견되는 호염성 그람음성 간균이며 주로 설사 및 위장관염을 일으킨다. 저자들은 71세 남자가 2주 전 해산물을 먹은 후 V. fluvialis에 의한 균혈증으로 내원한 드문 증례를 경험하였기에 보고하는 바이다. 그는 발열을 주소로 내원하여 혈액배양 검사에서 V. fluvialis가 확인되었고 수액 및 항생제 치료로 호전되어 내원 11일째 퇴원하였다. Vibrio fluvialis is a halophilic gram-negative bacilli usually found in sea water or seafood, and mainly cause gastroenteritis and diarrhea illness. We present a rare case of bacteremia caused by V. fluvialis in 71-years old man who has a history of sea food ingestion 2 weeks ago. He was admitted because of fever and V. fluvialis was isolated from blood. The patient was cured with fluid and antibiotics therapy and discharged after 11 days.

In this study, it will discuss the status of social conflict in the agricultural sector, the mixed-up state of positive and negative functional aspects of social conflict, and the policy issues regarding conflict management to increase positive functional aspects, based on literature review and survey of the interested parties. This study would suggest structural alternatives regarding the management of the latent or existent social conflict in the agricultural sector.

Sphingolipids play important roles in cell regulation and signal transduction. Recently, a sphingomyelin cycle has been described in which activation of neutral sphingomyelinase leads to the breakdowm of sphingomyelin and the generation of ceramide. Ceramide, in turn, has emerged as a candidate intracellular mediator for the action of certain cell agonists and has multiple biologic actions. Ceramide is a potent suppressor of cell growth and an inducer of apoptosis. The present studies show that exposure of IM-9 cells to ceramide resulted in internucleosomal cleavage of DNA, yielding laddered patterns of oligonucleosomal fragments characteristic of apoptosis. DNA fragmentation induced by ceramide was also confirmed by diphenylamine assay. The effect of ceramide on cell cycle progression was also studied. The addition of ceramide increased G1 phase distribution in cell cycle, Cell cycle-related cyclin D1 gene expression was decreased in a time-dependent manner. These results suggest that apoptosis induced by ceramide is related to cell cycle associated with the alteration of cell cycle in IM-9 cells.
