목적: 거대세포바이러스(Cytomegalovirus [CMV])는 정상 면역을 가진 사람에서는 대부분 불현성 감염이지만, 면역저하자 또는 태아의 선천 감염의 경우 위중한 합병증을 유발한다. 본 연구는 21년 동안의 시기 및 연령에 따른 CMV 항체 양성률을 조사하였다. 방법: 1995년 1월부터 2015년 12월까지 성균관대학교 의과대학, 삼성서울병원에서 CMV immunoglobulin G (IgG) 검사를 시행한 환자를 대상으로 하였다. 검사 결과는 성별, 연령별, 전국 지역별로 분석하였고, 두 시기에 따른 (1995-2005년; 1기, 2006-2015년; 2기) 항체 양성률의 변화를 분석하였다. 결과: 총 11,584명의 환자 중 CMV IgG 양성결과를 보인 총 환자는 10,900명 (94.1%)이었다. 전체 환자에서 두 시기에 따른 CMV 양성률의 차이는 없었다 (94.2% vs. 94.1%) (P=0.86). 10년 간격으로 비교를 했을 때 다른 연령군은 유의하지 않았으나 11-20세의 연령군의 CMV 양성률은 1기에 비해 2기에 더 낮았다 (P<0.001). 이 연령에 따른 항체 양성률 분석에서 31-40세 연령군의 항체 양성률 (97.4%)은 이보다 어린 연령군에 비하여 유의하게 높았으며 (P<0.001, odds ratio [OR]<1), 더 높은 연령군에 비하여 유의하게 낮았다 (P< 0.001, OR >1). 가임기 여성은 총 2,441명이었으며 (15-49세) 이 중 CMV IgG 양성률은 2,367 (97%)명이었다. 해당 연령군의 시기별 항체 양성률의 유의한 차이는 없었다. 가임기 여성 중 20-24세의 연령군은 해당 연령의 남자에 비하여 유의한 높은 항체 양성률을 보였다 (97.6% vs. 85.6%, OR, 6.78; 95% CI, 1.585-28.968; P=0.0028). 지역별 항체 양성률의 큰 차이는 보이지 않았다. 결론: 본 논문은 한국인의 전 연령의 CMV 항체 양성률 변화에 대한 조사를 시행한 최초 논문이며 전체적으로 약 94%의 높은 CMV 항체 양성률과 가임기 여성은 97%의 항체 양성률을 보이는 것으로 관찰되었다. 향후, 가임기 여성을 포함한 한국인의 CMV 항체 양성률의 변화 추세에 대한 모니터링과 국내 임산부에서의 CMV 감염에 대한 연구가 필요할 것으로 사료된다. Purpose: Cytomegalovirus (CMV) infection is mostly asymptomatic but can be detrimental to certain hosts. We investigated changes of CMV seroprevalence in Koreans before and after the year 2000. Methods: We reviewed laboratory values of patients who were tested for CMV immunoglobulin G (IgG) at Samsung Medical Center, Seoul, Korea, from January 1995 to December 2015. Changes in seroprevalence were analyzed by gender, age, region, and tested year period (period 1, 1995-2005 vs. period 2, 2006-2015). Results: Overall CMV seropositivity was 94.1% (10,900/11,584). There was no significant difference for CMV seropositivity among the two periods (94.2% vs. 94.1%) (P=0.862). CMV seropositivity in the 11 to 20-year age group in period 2 (78.8%) was significantly lower than that of period 1 (89.9%) (P=0.001). The seropositivity of individuals aged 31-40 years (97.4%) was significantly higher than that of younger age groups (P<0.001) and lower than that of older age groups (P<0.001). Of 2,441 females of reproductive age (from 15 to 49), CMV seropositivity was 97% (2,467/2,441). The seropositivity in women aged 20-24-years was higher than that of men in the same age group (97.6% vs. 85.6%, P=0.003). No significant difference was observed among different regions. Conclusions: Overall CMV seropositivity of Koreans was estimated to be 94% and the average seropositivity of reproductive women was 97%. Monitoring of the changes in seroprevalence including the reproductive age group is needed in the future.

Heading time is important element for yield and quality in crops. Among day length and temperature which influence on heading, temperature effect has not been investigated well. To investigate temperature effect on heading, heading date and plant growth characters were checked under the low and high temperature conditions in short day length. Analyzing heading date of six Korean varieties under the high and low temperature condition, heading date of varieties were delayed under low temperature. In the low temperature condition, dry weight and area of leaf were reduced. Varieties showing more delay of heading under low temperature also showed more reduction in leaf area. After selecting three varieties showing significant difference in leaf growth and heading date under different temperature conditions, nutrient contents of plant were analyzed. Nitrogen content was reduced in leaf and shoot under the low temperature condition. OsNRT2.3, nitrate transporter, was significantly down regulated in varieties showing more heading delay. Available phosphate content was decreased in leaf, but increased in shoot due to reduction of phosphate mobility. OsPT1, phosphate transporter regulating phosphate uptake, was more down regulated in varieties showing more heading delay. OsPT6, phosphate transporter regulating phosphate transport in plant, was also significantly down regulated in those varieties. With these data, we expected that active nitrogen and available phosphate uptake and transport in plant would increase leaf growth then might reduce heading delay under the low temperature condition.
