Background: A perioperative myocardial infarction(PMI) is one of the major complications after CABG. Among diagnostic methods of PMI, CK-MB activity assays have been increasingly replaced by CK-MB mass assays, which have more sensitive, simple measurement. Also, new cardiac-specific and -sensitive marker, cardiac troponin I(cTnl), has been shown to be a marker of myocardial infarction. We report our evaluation of clinical significance of CK-MB mass and cTnl as a marker of PMI after CABG. Material and Method: We studied 32 patients who underwent CABG at Kangdong Sacred Hospital between April 2000 and April 2001. Postoperative serum CK-MB activity level, serum CK-MB mass, cTnl, electrocardiogram, echocardiogram, and clinical data were recorded prospectively The diagnosis of PMI was defined as positive 2 among 3 or all of the following , by a new Q wave on the electrocardiogram, by serum CK-MB activity higher than 200 lU/L within 72 hours after operation, and by new regional wall motion abnormality on the echocardiogram. Result: After CABG, 3 patients had sustained a PMI according to current diagnostic criteria. As serum CK-MB activity time course, a level of CK-MB activity 12 hours after CABG had very linear correlated significance with serum CK-MB mass 24hours(R=0.946) and cTnl 48 hours(R=0.933) after CABG(p=0.000). As we used a receiver operating characteristics curve(ROC curve) for a diagnostic cutoff value in patients with PMI, serum CK-MB mass levels higher than 30.05 ug/L 24 hours after CABG detected the presence of PMI with an area under the ROC curve of 1.0, a sensitivity of 100%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 100%. Also serum cTnl levels higher than 17.15 ug/L 48 hours after CABG detected the presence of PMI with an area under the ROC curve of 0.98, a sensitivity of 100%, a specificity of 96.6%, a positive preclictive value of 75%, and a negative predictive value of 100% Conclusion: We concluded that both the measurement of CK-MB mass and cTnl are the easier, accurate methods as a diagnostic marker of PMT after CABG, also as a proposal of diagnostic cutoff value enables to an early detection of PMI. However, a 1arger number of patient will be needed because of statistic limitation that a small number of participating patients, a small number of PMI.

패션프루트(Passiflora edulis)는 브라질이 원산지이며 아열대와 열대지역에서 재배되고 있는 다년생 상록덩굴식물로 시계꽃과(Passifloraceae) 시계꽃속(Passiflora)에 속한다. 전 세계적으로 500여종이 분포하고 그 중 10여종은 식용, 나머지는 관상용으로 이용되고 있다. 지구온난화로 인한 기온상승으로 전남지역 재배에 적합한 대체 아열대과수 개발이 필요하다. 패션프루트는 겨울 최저온도가 $3^{\circ}C$이상 조건에서 재배 가능하여 남부 지역는 무가온 하우스재배를 하고 있지만 시설내 6월 하순부터 8월 중순까지 $35^{\circ}C$ 이상 고온이 지속되어 과실을 볼 수 없다. 8월 하순부터 피는 꽃은 인공수분으로 착과되어 11월부터 수확이 가능하지만 이후에 낮은 온도($10^{\circ}C$이하)로 착색이 진행되지 않아서 동해피해로 수확을 포기해야 한다. 어느 시기까지 인공수분을 해야 당년에 안정적인 수확이 가능한지를 알아보고자 패션프루트의 후기(2차) 개화시기 중에서 8월 30일, 9월 10일, 9월 20일, 9월 30일에 인공수분 하여 11월 하순에 착색이 정상적으로 진행되는 처리를 조사한 결과 8월 30일 처리구만 11월 21일 착색이 되었다. 미착색과에서 내용물이 진노랑색으로 진행되면 후숙하여 상품과로 판매가 가능하기 때문에 진노랑색에 도달한 시기를 조사하였다. 조사에서 9월 10일까지 인공수분 처리한 과실은 후숙하여 상품과로 판매가 가능하였다.

To study for proper growing conditions of Hydrangea macrophylla var. acuminata, used as ornamental trees or sources of natural sweetenings and biological active compounds, two-year-old cuttings of the plant were subjected to different conditions, light intensity, watering, and fertilizing levels. Photosynthetic rates measured on October 2 differed significantly between two light intensity regimes, but the values measured on September 3 were not significantly different. Mean photosynthetic rates on the plot watered three times a week were higher than the cuttings on the plot watered once a week. Mean photosynthetic rates on the plot fertilized 200grams/cuttings were slightly higher than those of the cuttings on the control plot. Chlorophyll contents measured on August 2 and on September 3 were significantly different between the light intensity regimes. Chlorophyll contents measured on August 2 were significantly different between the moisture regimes, but not significantly different between the fertilizing levels. Means of leaf growth(length and width) measured the highest values on the plot watered three times a week, and on the plot in full-sun lighted.
