The diagnosis of Duchenne Muscular Dystrophy (DMD) is typically achieved through blood cell analysis. However, this method can be invasive, leading to discomfort and the risk of infection. Moreover, in certain cases, collecting blood samples might prove challenging depending on the patients' condition. To address these concerns and enhance the convenience and safety of sample collection, this study aims to explore the use of non-invasive gargle samples for diagnosis. Gargle samples were collected from 22 healthy males and females, utilizing 10 mL of saline. The DNA extracted from the gargle samples underwent PCR amplification, focusing on exons 49 and 50, which are known for their high deletion frequency among the DMD genes. Subsequently, the nucleotide sequences of the amplified exons were confirmed. The PCR reaction product's sizes were found to be 439 bp in exon 49 and 271 bp in exon 50, which corresponded precisely with the results from the blood tests. Confirmation of the nucleotide sequences was performed through sequencing and was found to exactly match the corresponding exons. As a result, it was concluded that the diagnosis of DMD can be effectively achieved not only through the conventional invasive blood collection method but also through the non-invasive oral gargle method. This suggests that genetic diseases can be diagnosed in patients who might face challenges with blood sample visibility or experience a burden during blood collection by utilizing non-invasive methods.

듀센느근이영양증(DMD)의 진단은 일반적으로 혈액세포를 이용하여 이루어진다. 채혈은 침습적이며 불쾌감 과 감염의 위험이 있다. 또한 환자의 상태에 따라 채혈이 어려운 경우가 있다. 따라서, 본 연구는 검체 채취의 편의성 과 안전성을 도모하기 위해 비침습적인 방법으로 구강 가글액을 채취하여 예비 진단하고자 한다. 건강한 성인 남녀 22명을 대상으로 10 mL의 생리식염수를 이용하여 가글액을 채취하였다. 가글액 검체에서 DNA를 추출하고 DMD 유전자 중 결실빈도가 높은 49번과 50번 엑손을 PCR 방법으로 증폭한 후 염기서열을 확인하였다. PCR 반응산물의 크기는 49번 엑손에서 439 bp, 50번 엑손에서 271 bp로 나타났으며 이는 혈액검사에서 나타난 것과 동일한 결과를 나타냈다. 염기서열분석은 DMD 유전자 중 49번, 50번 엑손과 정확하게 일치하였다. DMD의 진단은 침습적인 채혈 방법뿐만이 아니라, 비침습적 구강 가글액 방법으로도 진단이 가능하다는 결론을 얻었다. 상대적으로 혈관이 잘 보이 지 않거나 혈액채취에 부담이 되는 환자들의 유전질환 진단은 비침습적인 방법으로도 가능할 것으로 사료된다.

Ever since next generation convergence technology became one of the most important industries in the nation, computing professionals have encountered a growing number of challenges. Along with scholars and colleagues in related fields, they have gathered in avariety of forums and meetings over the last few decades to share their knowledge, experiences and the outcome of their research. These exchanges have led to the founding of the International Next-generation Convergence technology (INCA) on December 1, 2015. INCA was registered as an incorporated association under the Ministry of Information and Communications. The main purpose of the organization is to improve our society by achieving the highest capability possible in next generation convergence technology.
