In the year 2013, onions cultivation in Jeonnam province suffered by frost-pillar damage. To reveal the aspects of the cause and outbreak, we surveyed those damaged areas. Usually the frost-pillar damage occurred in February. But the outbreak aspect is so unforeseeable. In 2013, the damage was shown as 10.6% in onion fields including paddy fields, but no damage was noticed in 2014. The damage was noticed as 77.8% in paddy fields and 30.1% in upland. And, by the difference of the onion transplanting date, it occurred as 0.7% by the middle of November to the early of November, 22% by the middle of November and 69.0% by the early of December. If one performed the supplementary planting at 3<SUP>rd</SUP> week of February, the highest survival percent was observed as 53.3%. If the date is early, another frost-pillar damage was occurred. If it’s late, the damaged plant was perished with dry. In any case, we found improper transplanting caused the yield decrease. Therefore, we recommend the timely transplanting is the most important way for the prevention of frost-pillar damage in the onion cultivation.

In this research, we surveyed the yield change of garlic cultivation with seed bulbs according to annual field culture after induced meristem culture. From 2007 to 2013, yearly produced seed bulbs from 2<SUP>nd</SUP> to 8<SUP>th</SUP> generation were cultivated in the Muan field. Over the generations, the general growth characteristics such as the plant height, leaf number, leaf length and stem diameter were all decreased. When we compared the conventional seed bulbs and TCR ones, the plant height and stem diameter showed bigger difference. And the TCR seed bulbs showed a week late harvest time against the conventional ones. The yield of 2<SUP>nd</SUP> generation was 72.3 g and 57.1 g for the 8<SUP>th</SUP> generation. However every generation showed higher yield than conventional seed garlic’s ones as 43.9 g. The yield index showed the same trend as 2<SUP>nd</SUP>- 8<SUP>th</SUP> to 63% to 21%. After the tissue culture of garlics, the viral infections (OYDV and GSV) of TCR was far less than that of conventional ones. In case of LYSV, the infection ratio was 6.7% at 2<SUP>nd</SUP> generation and 26% at 8<SUP>th</SUP>. However, the ratio was far less than that (80%) of the conventional ones.

Acute inhalational exposure to chlorine gas can cause reactive airway dysfunction syndrome (RADS) but only a few data are available on its long term sequelae. We experienced three cases of RADS induced by chlorine gas. Fifteen adults were accidentally exposed to chlorine gas at a local swimming pool because of an error in exchanging disinfectant. The exposure time was within 5 minutes. Most patients experienced throat irritation and sense of breathlessness. Three of them showed wheezing and obstructive patterns in pulmonary function tests and were diagnosed as RADS. Two of them received inpatient care for respiratory difficulty. Inhaled corticosteroid and bronchodilator were discontinued within a few months with resolution of obstructive lung impairment. At the 1-year follow-up, only one patient, demonstrated a positive response to the methacholine provocation test and needed anti-asthmatic medication for frequent nocturnal wheezing. After one year medication with inhaled corticosteroid and bronchodilator, he became free of symptoms and showed negative response to the methacholine provocation test. Another patients showed a borderline airway hyperresponsiveness (PC20=25 mg/mL) and the third patient had a negative test result without any symptoms. These two patients have not experienced any respiratory symptoms since they recovered from acute symptoms of RADS. (Korean J Asthma Allergy Clin Immunol 2009;29:283-288)

목적: 본 연구는 파종성혈관내응고(disseminated intravascular coagulation, DIC)에 대한 점수체계를 이용하여 중증패혈증 및 패혈증쇼크 환자에게서 파종성혈관내응고의 발생률과 예후를 확인하고자 하였다. 방법: 2008년 3월부터 2009년 2월까지 중증패혈증 및 패혈증쇼크으로 일개 3차 의료기관의 내과중환자실에 입원한 환자들을 대상으로 하였다. DIC 점수체계는 ISTH (International Society on Thrombosis and Haemostasis)를 이용하였으며, 연구기간 동안 각각 Day 0, Day 1, Day 2의 세 시점에서 계산 하였다. 결과: 총 111명의 환자 중에서 제외기준에 해당하는 22명을 제외하고, 89명의 환자가 연구에 포함되었다. 환자의 평균 DIC score는 3.3±1.3였으며, 입원 초기 48시간 동안에 현성 DIC (overt DIC; DIC score ≥ 5)의 발생 빈도는 33.8% (27/89)였다. Sequential Organ Failure Assessment (SOFA) score는 DIC score와 유의한 상관관계를 보여주었고, 현성 DIC 군에서 다른 환자군 보다 높은 점수를 보여주었다(p<0.05). 중환 자실 사망과 병원 사망, 28일 사망률은 현성 DIC 군에서 각각 63.0%, 66.7%, 63.0%이었고, 이는 현성 DIC에 해당되지 않은 환자에 비해 통계적으로 유의하게 높았다. 다변량 분석에서는 Simplified Acute Physiology Score (SAPS) II가 병원 사망과 유의한 관련성을 보여주었고(p=0.002), 현성 DIC의 발생은 경계선상의 관련성을 보여주었다(p=0.043). 결론: DIC 진단을 위해 ISTH criteria를 사용한 경우, 중증 패혈증 및 패혈증쇼크 환자에서 현성 DIC의 빈도는 33.8% 이었고, 현성 DIC의 발생은 높은 장기부전 점수 및 병원 사망률과 관련이 있었다. Background/Aims: We investigated the incidence and prognosis of disseminated intravascular coagulation (DIC) using DIC scoring system in patients with severe sepsis or septic shock. Methods: Patients admitted to the intensive care unit (ICU) in a tertiary hospital for severe sepsis or septic shock were enrolled from Mar. 2008 to Feb. 2009. Using the International Society on Thrombosis and Haemostasis (ISTH) criteria, we calculated DIC score at three time points (Day 0, Day 1, and Day 2). Results: Among 111 patients with severe sepsis or septic shock, 89 (severe sepsis, 8; septic shock, 81) were enrolled. Mean DIC score at ICU admission was 3.3±1.3 and the incidence of overt DIC (DIC score ≥ 5) during the first 48 hours was 33.8% (27/89). Sequential Organ Failure Assessment (SOFA) score was well correlated with DIC score and was higher in patients with overt DIC than in those without. The ICU, hospital and 28-day death rates in patients with overt DIC were 63.0%, 66.7%, and 63.0%, respectively, which were significantly higher than in those without overt DIC. In multivariate analysis, Simplified Acute Physiology Score (SAPS) II was significantly associated with hospital death (p=0.002), and the occurrence of overt DIC showed a borderline significance (p=0.053). Conclusions: Using the ISTH criteria for DIC, the incidence of overt DIC was 33.8% in patients with severe sepsis or septic shock. The occurrence of overt DIC was associated with a higher organ failure score and hospital outcomes. (Korean J Med 79:526-535, 2010)

Variceal bleeding occurs primarily in the esophagus or stomach in patients with liver cirrhosis, but can also occur rarely in the duodenum. Duodenal variceal bleeding has a high mortality and poor prognosis due to heavy blood flow originating from the portal vein (PV) and the technical difficulty of hemostatic procedures. Treatments including endoscopic sclerotherapy, endoscopic ligations, endoscopic clipping and transjugular intrahepatic portosystemic shunt have been tried, with only moderate and variable success. A percutaneous transsplenic approach offers another way of accessing the PV. Here we report a case of successfully treated duodenal variceal bleeding by percutaneous transsplenic embolization.

Paclitaxel takes effects as an anti-neoplastic agent by interfering with microtubules and then blocking cell growth. It has been used to treat patients with lung, ovarian, breast, head and neck cancer, and advanced forms of Kaposi`s sarcoma. Along with its reputation as an effective chemotherapeutic drug, paclitaxel has numerous adverse effects. Among them, cutaneous adverse effects of paclitaxel include pruritis, bullous fixed eruption, onycholysis, and transient erythrodysesthesia. Only several cases of scleroderma- like lesions have been reported throughout the world, and in Korea, only one case of paclitaxel induced scleroderma has been reported in 2006. We report a case of paclitaxel induced scleroderma in an 83-year old woman with ovarian cancer. After administration of paclitaxel and cisplatin, the patient presented with edema in both brachial areas, Raynaud`s phenomenon, and sclerotic skin lesions in both extremities.
