본 연구는 사상의학의 객관화 및 그 임상활동에 관한 유용한 자료를 제공함을 목적으로, 사상체질진단법에 의해서 분류된 태음인, 소양인, 소음인 그룹에 대하여 현재 유전적 분석 연구에 많이 사용되는 Amp-FLP법을 이용하여 VNTR인 MCT118(D1S80)과 STR중 3종의 locus (THO1, vWA, CSF1PO)를 대상으로 alleledistribution을 조사 작성하였다. 그리고 이러한 결과들은 Chi-square test를 통하여 통계학적인 유의성이 검토되었다. MCT118과 THO1은 각 체질별 집단의 특이성을 대변할 만한 유의적인 요소가 없는 것으로 나타났으나, vWA의 경우는 각 체질집단 중 소양인(0.002056)과 소음인($2.41{\times}10^{-10}$) 집단이 유의수준인 0.05보다 현저히 낮은 p-value를 나타내었다. 또한, CSFIPO에서도 소음인 집단이 $4.65{\times}10^{-17}$의 매우 낮은 p-value를 나타내었다. 따라서, 유의성 있는 차이를 보여준 vWA와 CSF1PO의 경우, 충분한 크기의 표본을 가지고 유전자 분석을 실시하여 위와 통일한 결과를 얻는다면 체질간 유전적 차이를 보여주는 지표로 사용될 수 있을 것으로 기대된다.

This study was carried out for the objectification and clinical application of the Sasang Constitutional Medicine(四象醫學). So, the Taeum Soyang, Soum groups were classified by diagnostic rules of Sasang constitution, and investigated by Amp-FLP method far genetic difference. The Amp-FLP was one of the most frequently used human genetic analysis methods which adopts STR typing. In this study, 100 genomic DNA samples of Taeum, Soyang, Soum constitution group were analysed by Amp-FLP method. Allele frequencies of four tetrameric short tandem repeat(STR) loci(TPOX, LPL, D21744, and D13S317) were determined in Taeum, Soyang, Soum groups. The heterozygosities and the polymorphism information content(PIC) values of forur STR loci were 0.812 and 0.789 in D3S1744, 0.811 in D13S317, 0.466 and 0.417 in LPL, and 0.625 and 0.561 in TPOX, respectively. The allele distribution of four STR loci was statistically evaluated. It was found out that the allele distribution of four STR loci was not significantly different among different constitutions. But all loci were found to be highly polymorphic in Taeum, Soyang, Soum groups. It was found out in this study that Taeum, Soum groups are genetically more related each other than they are related to Soyang groups.

최근까지 개인 식별 검사는 주로 단백질의 다형성을 보는 것이었으나, 분자생물학의 발달로 개인 식별 분야에도 DNA를 이용한 분석이 가능하게 되었다. 본 실험에서는 Thyroid Peroxidase(TPO)유전자의 다형성을 개인 식별 및 친자감별검사에 이용하기 위하여 그 기초조사로 한국인에서 TPO유전자의 대립유전자 발현빈도와 돌연변이율 등을 포함한 평가실험을 실시하였다 실험대상으로는 혈연관계가 없는 123명을 대상으로 말초혈액에서 DNA를 추출하고 PCR(중합효소연쇄반응)을 이용한 Amp-FLP방법을 이용하여 TPO 유전자를 증폭하였으며, polyacrylamide gel로 확인하였다. 그 결과 10개의 대립유전자와 29개의 유전형이 구분되었고, 이형접합성(Heterozygosity)은 70.7%였으며 돌연변이율은 0.075였고, 혈연 관계가 전혀 없는 두 사람이 동일한 유전자형 을 가질 가능성(Probability)은 14.6$\times10^{-2}$이었다. 또한 $x^2$=4.48, 0.05

The highly polymorphic variable number of tandem repeat (VNTR) loci in the human genome are informative markers for the genetic characterization of individuals in the paternity test and forensic science as well as for the study of human disease. In this study, VNTR loci D1S80 and D2S123 have been amplified by PCR and the amplified length polymorphic alleles were detected with a discontinuous vertical PAGE system and silver staining. For explicit DNA typing, PCR optimization, in which amplification efficiencies are similar over a wide range of allele sizes, non-specific amplifications are minimal, and new longer alleles have high amplification efficiency, has been performed by changing the PCR reaction buffer composition and thermal cycling conditions. It turned out that adding an appropriate amount of Tween 20 and NP40 to the PCR reaction buffer and raising the annealing temperature to $68^{\circ}C$ in thermal cycling made it possible for optimal VNTR loci amplification. A modified PAGE system for VNTR separation was established. Under these conditions, new longer alleles in the 01580 locus were discovered and 025123 pattern changes in colorectal tumors were observed. These technical tips are valuable for detecting various amplified fragment length polymorphisms.

Conventionally, identification and classification methods of natural products include the morphological survey and assay of chemical disposition, sing these methods, however, is not satisfying for the precise identification of natural products because they are often valiable in the compositions and morphology To standardize the natural products identification and classification, genomic DNA analysis such as RAPD, RFLP and Amp-FLP can be adopted for this purpose. In this study, various ginsengs and bear gall bladder were tested for the development of genetic identification and classification method. Varieties of ginsengs such as, P. ginseng, P. quinquefolium, P. japonicus and P. notoginseng, were genetically analyzed by RAPD. Also, DNA isolated from Bear blood and gall bladder, Ursus thibetanus, Ursus americanus and Ursus arctos, were analyzed by the same method. The results demonstrated that the identification and classification of bear gall bladder and various ginsengs were possible by RAPD analysis. Therefore, this method was thought to be used as a additional method for the identification and classification of other natural products.
