Abstract

Ethylene glycol (EG) is the most commonly used for automotive antifreeze, and it's easily misuseful for human. EG poisoning occurs in suicide attempts and infrequently, either intentionally through misuse or accidentally because of sweet taste. Though EG itself is mild toxic to the human body, it becomes higher toxic organic acids by in vivo broken down that are responsible for extensive cellular damage in various tissues caused principally by the metabolites. It is already well known that various cellular stresses induce gene expression of endoplasmic reticulum (ER) chaperones and ER stress sensors. This study demonstrated that regulation of gene expression of ER chaperones and ER stress sensors was induced by EG in rat tissues, and in tissues histological changes are also detected by both staining H&E and immunofluorescent.

에틸렌 글리콜(ethylene glycol)은 자동차 부동액 주성분으로 우리 실생활에 널리 쓰이고 있다. 접근이 용이하고 달콤한 맛 때문에 자살목적이나 보관 및 사용 시 의도적으로 또는 실수로 인한 오용사고가 자주 발생한다. 에틸렌 글리콜은 그 자체로는 인체의 독성이 낮지만 생체에서 대사과정을 거치면서 독성이 높아진 유기산을 만들어 다양한 조직에서 광범위한 세포손상을 유발한다. 다양한 세포 스트레스가 소포체(ER) 샤페론과 소포체 스트레스 센서의 유전자 발현을 유도하는 것은 이미 알려져 있다. 본 연구에서는 rat 조직에서 소포체 샤페론과 소포체 스트레스 센서 유전자의 발현 조절이 에틸렌 글리콜에 의해 유도되고, 조직학적 변화도 H&E 염색 및 면역 형광염색에 의해 확인하였다.
