<P>Sophorae Radix (<I>Sophora flavescens </I>Aiton) has long been used in traditional medicine in East Asia due to the various biological activities of its secondary metabolites. Endogenous contents of phenolic compounds (phenolic acid, flavonol, and isoflavone) and the main bioactive compounds of Sophorae Radix were analyzed based on the qualitative HPLC analysis and evaluated in different organs and at different developmental stages. In total, 11 compounds were detected, and the composition of the roots and aerial parts (leaves, stems, and flowers) was significantly different. trans-Cinnamic acid and<I> p</I>-coumaric acid were observed only in the aerial parts. Large amounts of rutin and maackiain were detected in the roots. Four phenolic acid compounds (benzoic acid, caffeic acid, ferulic acid, and chlorogenic acid) and four flavonol compounds (kaempferol, catechin hydrate, epicatechin, and rutin) were higher in aerial parts than in roots. To identify putative genes involved in phenolic compounds biosynthesis, a total of 41 transcripts were investigated. Expression patterns of these selected genes, as well as the multiple isoforms for the genes, varied by organ and developmental stage, implying that they are involved in the biosynthesis of various phenolic compounds both spatially and temporally.</P>

연구배경 : 허혈성 심자병 환자가 사망하는 것은 주로 심실성 부정맥에 의한 돌연사라고 알려져 있으며 드물게 운동과 연관되어 나타난다고 한다. SA-EKG는 일반 심전도로 기록할 수 없는 심장의 미소한 전기적 활성을 기록하기 우해 개발되었는데 지금까지 심장의 돌연사 위험을 평가하는 비관혈적 방법으로 이용되어 왔으나 운동이 여기에 미치는 영향에 대한 연구는 비교적 적다. 방법 : 협십증과 심근 경색증 환자에게 안정시 SA-EKG 소견을 관찰하고 이들 소견의 운동후의 변화를 평가하기 위하여 대조군 189명, 협심증군 82명, 심근경색증 49에서 운동부하 검사 전후에 SA-EKG를 기록하여 f-QRS, RMS, HFLA 변화를 비교분석하였다. 결과 : 1) 대조군에서 운동후 평방근평균전위(RMS)는 의의있게 증가했고 고주파 저전위의 기간 (HFLA)은 의의있게 감소했다(p<0.05). 2) 운동전 지연전위가 양성이었던 예가 운동후 음성으로 변화한 경우는 대조군 52.4%, 협심증군 37.5%, 심근경색증군 40.0%이었고, 비정상 SA-EKG가 운둥후 정상으로 변화한 경우는 대조군 48.3%, 협심증군 22.2%, 심근경색증군 45.5% 이었으며 각 군간에 유의한 차이는 없었다. 3) 운동전 지연전위가 음성이었던 예가 운동후 양성으로 변화한 경우는 대조군 2.4%, 협심증군 6.1%, 심근경색증군 2.6%이었고, 정상 SA-EKG가 운동후 비정상적으로 변화한 경우는 대조군 1.9%, 협심증군 4.7%, 심근경색군 2.6% 이었으며 각군간에 유의한 차이는 없었다. 결론 : 허혈성 심장병의 동반 유무에 상관없이 등장성 운동후에 국소심근에 존재하는 전도지연이 개선될 수 있음을 시사하였다. Background: Major cause of sudden death in patients with ischemic heart disease is ventricular arrhythmia and associated with exercise. Recently signal averaged EKG (SA-EKG) is developed to record microelectrical potential that can t be detected in surface EKG and have been used evaluating the risk of sudden death in patients with ischemic heart disease, but few studies are reported for the effect of exercise on this. Method : To investigate the findings of signal averaged EKG (SA-EKG) in normal subjects(n=189), angina pectoris paitents(n=82) and myocardial infarction patients(n=49) and the effect of isotonic exercise on them, we analysed SA-EKG s recorded before and after treadmill exercise test. Result : In group A root mean square voltage (RMS) was significantly increased (p< 0.05) while duration of high frequency low amplitude activity (HFLA) was significantly decreased (p<O. 05) after exercise and duration of filtered QRS (f-QRS) was insignificantly decreased. In group B and group C, f-QRS and HFLA were insignificantly decreased while RMS was increased insignificantly. In considerable proportion of the subjects, the positive late potential (LP) was converted to negative LP after exercise, i.e. 52.4% in group A, 37.5% in group B, and 40.0% in group C and also the abnormal SA-EKG converted to normal SA-EKG, i.e. 48.3% in group A, 22.2% in group B, and 45.5% in group C. On the contrary in smaller proportion of the subjects the negative LP was converted to positive LP after exercise, i.e. 2.4% in group A, 6.1% in group B, and 2.6% in group C, and the normal SA-EKG converted to abnormal SA-EKG, i.e. 1.9% in group A, 4.7% in group B, and 2.6% in group C. There was no significant differences among groups in the conversion rates of SA-EKG findings after exercise. Conclusion : Slow conduction demonstrated by SA-EKG could be improved after isotonic exercise whether it is associated with ischemic heart disease or not.

In 2019, ‘Bodeuremi’ was developed as a high-yielding sweetpotato variety with good palatability. It was derived from a cross between ‘MI2006-58-02’ with high yield and ‘Beniharuka’ (IT309504) with good palatability. The storage roots of ‘Bodeuremi’ have a red skin, light orange flesh, and an ovate shape. When steamed, ‘Bodeuremi’ storage roots exhibit a moist texture and are more tender than those of the check variety ‘Pungwonmi’. The sugar content of steamed ‘Bodeuremi’ storage roots was 33.4 mg/100 g dw, which was 6.0% higher than that of ‘Pungwonmi’. The marketable yield of ‘Bodeuremi’ storage roots was 30.3 MT/ha in the early season culture, which was 4.5% higher than that of ‘Pungwonmi’ with high yield in the early season culture. ‘Bodeuremi’ is resistant to root-knot nematode and moderately resistant to Fusarium wilt. ‘Bodeuremi’ is expected to contribute to increased income of sweetpotato growers as it has high cultivation stability and can be shipped at a time when the market price is high owing to its high yield in the early cultivation.

‘Dahomi’, a new sweetpotato variety, was developed for table use by the sweetpotato breeding team of Bioenergy Crop Research Institute, National Institute of Crop Science (NICS), RDA in 2012. This variety was derived from the cross between ‘Muan4’ and ‘Jinhongmi’ in 2005. The seedling and line selections were performed from 2007 to 2008, preliminary and advanced yield trials were carried out from 2009 to 2010, and the regional yield trials was conducted at five locations from 2011 to 2012 and it was named as ‘Dahomi’. This variety has three or five lobes leaf, green leaf, stem, and petiole. Storage root of ‘Dahomi’ was elliptic, red skin, light orange flesh. This variety is resistant to fusarium wilt, but susceptible to root-knot nematode. Texture of steamed storage root was intermediate, and degree Brix of steamed storage root was 24.8 °Brix. The total sugar content of raw and steamed storage root was 9.7, 32.0/100 dry weight (g), respectively, which was higher than that of ‘Yulmi. Storage root yield of ‘Dahomi’ was 26.3 MT/ha under the early seasonal cultivation, which was 52% higher than that of ‘Yulmi’. Storage root yield of ‘Dahomi’ was 21.9 MT/ha under the optimum and late seasonal cultivation, which was 35% higher than that of ‘Yulmi’. The number of storage roots over 50 g per plant was 2.8 and the average weight of storage root was 138 g under the optimum and late seasonal cultivation.
