Abstract

This study was conducted to determine the antiseptic effect of stabilized chlorine dioxide (S-$ClO_2$) on muscle tissue of rats. Skeletal muscle of 8-week old Sprague-Dawley rats was used. Light and transmission electron microscopic findings were observed in the control group, which was not treated with stabilized chlorine dioxide, and in the experimental group, which was treated with a stabilized chlorine dioxide powder in aqueous solution. According to the LM and TEM observations, the day 1 control group showed the initiation of endomysium collapse resulting in an unclear boundary of muscle fibers, and partial collapse of the mitochondrial membranes. All endomysium had collapsed, and bacteria were observed among muscle fibers in the day 2 and later groups. Shapes of muscles were not distinguishable in day 3 or later groups. In contrast, the day 1 and 3 experimental groups revealed detailed structure of typical muscles, but partial collapse of the mitochondrial membranes was observed in the day 3 and later groups. Subsequently, connective tissues collapsed and structures in the shape of concentric circles were observed. In summary, the day 1 control group showed the initial collapse of tissues, and shapes were not distinguishable in the day 3 and later groups because most of the tissues had collapsed. In contrast, the day 3 experimental group showed partial collapse, but the overall shapes of muscles were maintained as time went on, confirming the antiseptic effect of stabilized chlorine dioxide on muscles.

강한 산화력과 소독효과로 인해 광범위하게 사용되고 있는 안정화 이산화염소(S-$ClO_2$)의 근육조직에 대한 부패억제 효과를 알아보고자 본 연구를 수행하였다. 본 실험을 위해 8주령 SD계 흰쥐 골격근(skeletal muscle)을 사용하였고, 안정화 이산화염소를 처리하지 않은 대조군과, 안정화 이산화염소의 분말과 수용액을 처리한 실험군으로 분류하여 광학 및 투과전자현미경으로 관찰하였다. 광학현미경 관찰 결과, 대조군 1일부터 근섬유막이 분리되기 시작하였고 핵의 붕괴가 관찰되었다. 2일군에서는 근섬유막이 붕괴되어 근섬유의 형태만 남아 있었고, 근원섬유도 붕괴되는 양상을 나타내었다. 3일군 이후 대조군의 경우는 대부분의 근섬유막과 결합조직의 붕괴로 근섬유의 구분이 불분명하였다. 실험군의 경우, 3일군에서 근섬유 사이 결합조직의 부분적인 붕괴가 관찰되었다. 그러나 4, 5일군에서도 3일군과 유사한 양상을 나타내었다. 한편, 전자현미경적 소견은 대조군의 경우 1일군부터 근섬유막의 붕괴로 근섬유의 경계가 불분명하였고, 미토콘드리아막도 부분적인 파괴가 관찰되었다. 2일째부터 근섬유막이 모두 붕괴되었고 근섬유 사이에서 세균이 관찰되었다. 3일군 이후는 근육의 형태를 구별할 수 없었다. 그러나 실험군의 경우, 1일과 2일군은 전형적인 근육의 미세구조를 관찰할 수 있었고, 3일군부터 부분적인 미토콘드리아막의 붕괴가 관찰되었다. 이후 시간경과에 따라 결합조직이 붕괴되어 동심원상의 구조물이 일부 관찰되었다. 따라서 본 연구결과, 대조군은 1일군부터 조직의 붕괴가 시작되어 3일군 이후는 대부분 붕괴되어 형태를 구분할 수 없었으나, 실험군의 경우는 3일군부터 부분적인 붕괴가 시작되었고 이후 시간이 경과되어도 전체적인 근육의 형태가 유지되어 안정화 이산화염소가 근육에 부패억제 효과가 있는 것으로 확인되었다.
