  • The incidence rates of postharvest fruit rots of four kiwifruit cultivars which were cultivated under rain-proof tunnel house at a same orchard were examined. Among them, 'Halla-Gold', 'Jecy-Gold' and 'Jecy-Sweet' were new cultivars bred in Korea. The disease incidence was varied with cultivars; 74.8%, 65.3%, 57.1% and 16.2% for 'Hayward', 'Halla-Gold', 'Jecy-Sweet' and 'Jecy-Gold' cultivars, respectively. Two hundred and eighteen isolates were obtained from diseased fruits and identified by mycological and molecular biological methods. Three fungi, Botryspheria dothidea, Diaphorthe actinidiae and Botrytis cinerea, were identified as pathogens of the postharvest fruit rots with detection rates of 95.4%, 4.6% and 2.3%, respectively.

  • In this study, viral disease samples were obtained between 2006 and 2010 from pepper fields in 11 major pepper-growing districts in Gangwon-do, and in 83 areas from other provinces, with the exception of Gyeongsangnam-do and Jeju island in Korea. In order to assess the type of infection, field surveys were conducted with regard to viral disease severity and virus type, based on typical symptoms on leaves. The means of single and mixed-virus infections were 46.6% and 48.0%, respectively, during those periods, suggesting that viruses are the agents that most severely decrease pepper production in field cultivation in Korea. In terms of single infection, Cucumber mosaic virus (CMV) was the most prevalent virus based on its disease severity ratings (34.8%). Next, Pepper mild mottle virus (PMMoV) and Pepper mottle virus (PepMoV) were shown to cause severe viral diseases in pepper, with disease severities of around 5-10%. On the other hand, Tomato spotted wilt virus (TSWV) occurs in a limited area in Chungcheongnam-do and Jeollanam-do. Thus, the viral disease caused by CMV, PMMoV, and PepMoV in pepper can be severe, and these virus types should remain considered critical reasons for decreased pepper production in field cultivation in Korea. In addition to single infection, mixed infections are frequently observed in collected pepper samples from all areas. The ratios of mixed infection were therefore studied to evaluate the disease severity of mixed infections and to define individual virus types. These data showed that different types of viruses were present, and CMV was the most abundant virus for mixed infection, as in the case of single infection. Among mixed infections, the highest disease severity was seen with CMV+Broad beam wilt virus 2 (BBWV2), followed by other types of mixed infection such as CMV+PepMoV and CMV+PMMoV. However, further work is needed to reduce the severe damage caused by viruses and to assess mixed infection types involving three or more viruses.

  • 최근 급속한 산업화와 경제발전으로 인해 소득수준이 향상되면서, 고단백질 및 고지방질 식품의 섭취 및 운동부족으로 인한 성인병, 특히 비만증, 고지혈증, 당뇨병 및 심장순환기계질환이 급속히 증가되어 사회문제로 대두되었고, 한국을 포함한 선진각국의 고지혈증 및 심장순환기계질환의 발병빈도가 여전히 증가추세에 있다. 보건위생의 여건이 좋아지면서 전염성질환이 줄어들었으나, 심장 순환기 질환의 발병률은 계속 증가추세에 있고, 순환기질환은 고지혈증에 의하여 발병되며 이 질환의 사망률은 전체 사망률 중 상위를 차지하고 있다. 인간은 고지혈증에 의한 동맥경화로 인한 사망률은 전체 사망률 중에서 상위를 차지하고 있으며, 그에 따른 의약품의 개발이 요구되고 있고, 현재 임상적으로 사용되고 있는 고지혈증 치료제로는 체내의 cholesterol 생합성 저해제가 있으나, 보다 제한사항이 없고, 작용기작이 확실하며 부작용이 적은 새로운 고치혈증 치료제의 개발이 요구되고 있다. 콜레스테롤은 세포막의 구성과 스테로이드 호르몬의 전구체로서 생체를 구성하는데 필수적인 요소이지만 과다하게 공급되었을 경우 동맥경화와 같은 심혈관계 질환을 유발할 수 있다. 체내에 콜레스테롤의 공급은 체외 음식물로부터 섭취하는 방법과 체내에서 생합성에 의해 공급되는 방법이 있는데, 서로 유기적인 보완관계를 유지하면서 필요한 콜레스테롤의 양을 유지한다. 그러나, 현대인의 식생활이 급격한 서구화로 체외로부터 필요량 이상으로 콜레스테롤이 유입되어 각종 성인병 발명의 상승 요인이 되고 있다.

  • 혈관은 혈액을 온몸으로 순환시키는 관으로 인체의 모든 장기는 혈관을 통해 영양을 공급받는다. 그러므로 혈관 내에 찌꺼기가 쌓이고 두꺼워지면 심근경색, 뇌졸중, 혈류장애 등과 같은 혈관질환 발병률을 높이고 최악에는 사망으로 이어진다. 통계청의 자료에 의하면 작년 한 해 뇌혈관질환이 사망률 2위, 심장질환이 3위를 차지하면서 한국인의 사망원인 대다수가 혈관질환과 관련 있는 것으로 나타났다.

  • In order to select the optimum rice cultivars for the use in processing of eco-friendly-grown germinated brown rice (GBR), disease incidences and yields in rice cultivars bred in National Institute of Crop Science were investigated in eco-friendly paddy fields (Gokseong, Jeonnam Province, Korea) during the years 2009-2011. The incidences of rice sheath blight and blast on the cultivar Samgwang were higher than those on one reference cultivar Chucheong, but much lower than those on the other reference cultivar Gosihikkali. The cultivars Keunnun and Haiami selected as special rices showed disease incidences and yields similar to the reference rice cultivars Chucheong and Gosihikkali. These results indicated that the cultivars Samkwang, Keunnun, and Haiami can be selected as rice cultivars for the use of in processing of eco-friendly grown GBR because their disease incidences and yields in Gokseong may be similar to the reference cultivars.
