본 발명은 아크리딘 오렌지형광염색을 이용한 방사성 고사세포 신속검출방법에 관한 것으로서 보다 상세하게 기술하면 다음과 같다. 먼저, 감마선 발생장치를 이용하여 조사된 림프구를 원심분리 배양하고, 슬라이드를 제작한 후 고농도아크리딘 오랜지 보존액(0.1%)을 소렌센 인산완충용액으로 희석한 다음 슬라이드에 떨어뜨리고, 커버글라스 포배하여 고사세포 사멸체를 형광현미경으로 확인하는 것이다. 본 발명의 결과로 살아있는 세포와 고사세포 그리고, 괴사세포로 명확하게 구분이 가능하고, 단시간에 다량의 세포를 분석할 수 있게 되어 경제적이면서 작업시간을 대폭 줄일 수 있는 아크리딘 오렌지형광염색을 이용한 방사성 고사세포 신속검출방법에 관한 것이다.The present invention relates to a method for rapid detection of radioactive apoptosis cells using acridine orange fluorescence staining. First, the lymphocytes irradiated with a gamma ray generator were centrifuged and cultured. After the slides were prepared, the diluted acryldin orange stock solution (0.1%) was diluted with Sorensen phosphate buffer solution, dropped on the slides, and cultivated with cover glass. Apoptotic apoptosis is confirmed by fluorescence microscopy. As a result of the present invention, it is possible to clearly distinguish between living cells and apoptosis cells and necrotic cells, and to analyze large amounts of cells in a short time using acridine orange fluorescent staining, which is economical and can significantly reduce working time. It relates to a method for rapid detection of radioactive dead cells.

일반적으로 방사선에 대한 생물학적 영향, 특히 인체영향을 판단하는데 있어서 혈액이나 조직세포의 형태ㆍ조직학적 변화를 관찰하는 방법이 이용되고 있는데, 관찰방법 중 검출 예민도가 높은 염색법이 선택되어 활용된다. 이런 측면에서 볼 때, 기존에 개발되어 이용되고 있는 생물학적 선량-반응 측정법들은 염색체 이상을 기준으로 보다 간편하고, 짧은 시간에 대량의 시료를 분석하고자 노력한 산물이라고 할 수 있다.In general, a method of observing the morphological and histological changes of blood or tissue cells is used to determine biological effects on radiation, in particular, human effects. Among the observation methods, a staining method having a high detection sensitivity is selected and used. In this respect, the existing biological dose-response assays that have been developed and used are simpler, based on chromosomal aberrations, and are the product of efforts to analyze large samples in a short time.

그러나, 이들 방법들을 이용하여 세포 형태학적 변화를 관찰하는 경우에는 전문적인 지식과 고가의 장비, 시간적 소용이 없이는 분석이 어려웠을 뿐만 아니라 다량의 시료를 처리하는데 한계를 보였다. 다시 말해서, 선량-반응관계를 관찰하기 위해서는 민감성이 높고, 간편하면서 빠른 시간에 대량의 시료를 처리할 수 없는 문제점이 있었다.However, when observing cell morphological changes using these methods, the analysis was difficult without the expert knowledge, expensive equipment, and time use, and showed a limitation in processing a large amount of samples. In other words, in order to observe the dose-response relationship, there is a problem that a large amount of samples cannot be processed in a high sensitivity and simple and fast time.

한편, 현재 세포고사기전의 증명을 위하여 사용되고 있는 방법론으로는 유세포 분석기 활용법, in situ DNA결합법, 전기영동에 의한 DNA단편물 확인법 등이 단독 또는 혼용되어 이용되고 있으나, 유세포 분석기를 이용하는 경우에는 데이터의해석에 개인적인 주관이 개입될 수가 있고, in situ DNA결합법과 전기영동법 등을 활용하는 경우에는 시약 및 기구가 고가일 뿐 아니라 관찰자의 전문적인 지식이 요구되기 때문에 방사선에 대한 피폭선량 평가나 생물학적 인체영향 평가를 위하여 요구되는 신속, 정확, 간편이라는 충족요건을 만족시키기에는 많은 불편한 점이 있었다.On the other hand, as the methodology currently used for the demonstration of cell death mechanism, flow cytometry, in situ DNA binding, electrophoresis and DNA fragment identification method are used alone or in combination, but in the case of using flow cytometry, Individual subjects can be involved in the seat, and in situ DNA binding and electrophoresis methods require reagents and instruments to be expensive, and require expert knowledge of the observer. There have been many inconveniences in meeting the requirements for speed, accuracy and simplicity required for impact assessment.

이를 개선하기 위한 본 발명의 목적은 방사선에 대한 생물학적 영향을 세포수준에서 정밀하게 해석하기 위해서는 기존에 개발되어 활용화되고 있는 방법론들에 비교하여 간편하면서 장소에 구애를 받지 않고, 누구나 손쉽게 이용할 수 있으면서 관찰오차를 줄이는 데 있다.The purpose of the present invention to improve this is to compare the methodologies that have been developed and utilized in order to precisely interpret the biological effect on radiation at the cellular level, it is simple and can be used anywhere, and can be easily used by anyone. To reduce observation errors.
