본 연구는 chitosan-ascorbate (CA) 첨가(0.1%)가 물김치의 숙성에 미치는 영향과 고콜레스테롤식이 흰쥐의 혈청지질에 미치는 효과를 조사하였다. CA첨가 물김치는 무첨가에 비하여 탁도가 낮고, 보존성이 높으며, glucosamine함량이 무첨가에 비하여 배, SOD활성이 로 높았으며 2025 kDa의 chitosan으로 제조한 CA2025가 가장 양호하였다. 동물실험은 SD계 흰쥐로 정상식 이군(NC), 고콜레스테롤 식이군(HC

다량의 페놀류 2차 대사산물과 다당류가 포함된 녹두 종자의 RNA를 Tris-buffer와 guanidium thiocyanate 용액을 이용하여 손쉽고 간편하게 고순도의 RNA를 분리하는 방법을 확립하였으며, 우리의 분리 방법을 이용하여 추출한 RNA를 사용하여 RT-PCR과 유전자 클로닝 등의 분석시험에 이용할 수 있었다.

It is important to understand pedigree of rice cultivars commonly used for breeding. In this paper, pedigree tables for tracking the pedigree of 17 representative rice cultivars recommended by Rural development Adminstration (RDA) were completed and analyzed using two kinds of web database system; 'IRIS' and 'RRDB'. Seven cultivars, namely, 'Sangmibyeo', 'Ilpumbyeo', 'Saegewhabyeo', 'Surabyeo', 'Shindongjinbyeo', 'Ilmibyeo' and 'Jungwhabyeo' had 'Koshihikari' on the pedigree of their ancestor. Besides 'Koshihikari', the most feguently used ancestral germplasms among the high quality rice cultivars were 'Fujisaka 5', 'Kameno o' and 'Asahi', 'Fujisaka 5' was used as ancestral parent in 12 out of 17 cultivars. Interestingly, 'Kameno o' was used in pedigree of 16 out of 17 high quality varieties and 'Asahi' was used in the ancestral pedigree of all 17 varieties. 'Hwayeongbyeo' was used as one of parent in the breeding of 'Dongjin 1', 'Hwabongbyeo', 'Saegewhabyeo' and 'Junambyeo'. 'Ilpumbyeo' was used in the breeding pathway of 'Junambyeo' and 'Saegewhabyeo', 'Mangeumbyeo' itself was not enlisted as one of high quality rice cultivars, but was used as a breeding parent of three high quality varieties, namely, 'Saegewhabyeo', 'Hwabongbyeo' and 'Nampyeongbyeo'. Incorporated with evaluation data, pedigree will provide a valuable chance to genealogical tracking of agronomic traits such as disease resistance, grain quality and etc.
