  • Circulatory arrest under deep hypothermia is an important auxiliary means for cardiac surgery, especially useful in pediatric patients. However, its clinical safety, particularly with regard to the neurologic outcome after long duration of circulatory arrest, is still not established. This study is a review of the eight years'clinical experience of hypothermic circulatory arrest at the Seoul national University Children's Hospital. During an eight-year period from January 1986 through December 1993, a total of 589 consecutive cardiac operations were done using circulatory arrest under deep hypothermia. Among them, 434 consecutive patients, in whom the duration of arrest was 20 minutes or more, are the subject of this study. The duration of arrest ranged from 20 minutes to 82 minutes (mean = 38.7 minutes) under rectal temperature in the range from 12.5$^{\circ}C$ to 25.8$^{\circ}C$. Early neurologic abnormalities occurred in 47 patients : seizure attacks in 28 patients, motor paralyses with or w thout seizure in 12, blindness in 2, and no recovery of consciousness in 5 patients. The rate of incidence of early neurologic abnormalities was calculated at 15.7%. 25 patients showed late neuropsychologic sequelae, such as motor paralysis (9 patients), recurrent seizures (6), developmental delay (8), and definitely low intelligence (2). The rate of incidence of late neurologic sequelae was 8.5%, By statistical analysis, the following factors were identified as the risk factors for post-arrest neurologic abnormalities ; 1) long duration of circulatory arrest, 2) lower-than-ideal body weight, 3) preexisting neurological abnormalities, 4) associated non-cardiovascular congenital anouialies, and 5) low blood pressure during the early post-arrest period. It is concluded that circulatory arrest under deep hypothermia is a relatively safe means for pediatric cardiac surgery with acceptable risk. However, to warrant maximal safety, it is desirable to limit the duration of arrest to less th n 40 minutes. In addition, it is our contention that the early post-arrest period is a very critical period during which maintenance of adequate perfusion pressure in important for the neurologic outcome.

  • Objectives: A vertebral compression fracture (VCF) is characterized by back pain and fracture of a vertebral body on spinal radiography. VCFs of the thoraco lumbar spine are common in the elderly. In general, appropriate analgesics should be prescribed to reduce pain and, thus, promote early mobilization. The ideal treatment approach for VCFs has not been determined. In Korea, acupuncture and herbal medication have been used to treat VCFs for many years. There is empirical evidence that acupuncture might benefit patients with a VCF. However, no randomized, controlled, clinical trials evaluating the efficacy and the safety of acupuncture for treating a VCF have been published. Therefore, we designed a randomized, controlled, pilot, clinical trial to obtain information for the design of a further full scale trial. Methods: A five week protocol for a randomized, controlled, pilot, clinical trial is presented. Fourteen patients will be recruited and randomly allocated to two groups: a control group receiving interlaminar epidural steroid injections once a week for three weeks, and an experimental group receiving interlaminar epidural steroid injections plus acupuncture treatment (three acupuncture sessions per week for three weeks, nine sessions in total). The primary outcomes will be the pain intensity (visual analogue scale and PainVision$^{TM}$ system). The secondary outcome measurements will be the answers on the short form McGill pain questionnaire and the oswestry disability index. Assessments will be made at baseline and at one, three, and five weeks. The last assessment (week five) will take place two weeks after treatment cessation. This study will provide both an indication of feasibility and a clinical foundation for a future large scale trial. The outcomes will provide additional resources for incorporating acupuncture into existing treatments, such as nonsteroidal anti-inflammatory medications, narcotics and vertebral augmentation. This article describes the protocol.

  • Objectives: This study estimated the association of cardiovascular health behaviors with the risk of all-cause and cardiovascular disease (CVD) mortality in middle-aged men in Korea. Methods: In total, 12 538 men aged 40 to 59 years were enrolled in 1993 and followed up through 2011. Cardiovascular health metrics defined the following lifestyle behaviors proposed by the American Heart Association: smoking, physical activity, body mass index, diet habit score, total cholesterol, blood pressure, and fasting blood glucose. The cardiovascular health metrics score was calculated as a single categorical variable, by assigning 1 point to each ideal healthy behavior. A Cox proportional hazards regression model was used to estimate the hazard ratio of cardiovascular health behavior. Population attributable risks (PARs) were calculated from the significant cardiovascular health metrics. Results: There were 1054 total and 171 CVD deaths over 230 690 person-years of follow-up. The prevalence of meeting all 7 cardiovascular health metrics was 0.67%. Current smoking, elevated blood pressure, and high fasting blood glucose were significantly associated with all-cause and CVD mortality. The adjusted PARs for the 3 significant metrics combined were 35.2% (95% confidence interval [CI], 21.7 to 47.4) and 52.8% (95% CI, 22.0 to 74.0) for all-cause and CVD mortality, respectively. The adjusted hazard ratios of the groups with a 6-7 vs. 0-2 cardiovascular health metrics score were 0.42 (95% CI, 0.31 to 0.59) for all-cause mortality and 0.10 (95% CI, 0.03 to 0.29) for CVD mortality. Conclusions: Among cardiovascular health behaviors, not smoking, normal blood pressure, and recommended fasting blood glucose levels were associated with reduced risks of all-cause and CVD mortality. Meeting a greater number of cardiovascular health metrics was associated with a lower risk of all-cause and CVD mortality.

  • 한국의 주요 고문헌 기관과 이들 기관이 소장한 고문헌이 디지털화 된 진도와 그 내용을 분석하였다. 이 고문헌을 이용하기 위한 연합조직을 검토하였다. 국가의 고문헌 디지털화를 위한 정책과 향후계획을 파악하였다. 고문헌의 디지털화를 위한 절차와 필요조건을 제안하였다. (1) 1980년대에 추진하기 시작한 국가도서관 대학도서관 문도서관 등의 도서관 관리 검색 이용 시스템의 디지털화는 이미 상당한 수준에 도달하였다. 고문헌의 소장량은 상당히 많고 내용적 가치도 높다. 일부 디지털화 된 자료는 이미 Internet을 통하여 제공되고 있다. 그러나 전반적으로 고문헌의 디지털화 된 수준은 아직도 궤도에 오르지 못한 상태로 분발이 요구된다. (2) 이미 제공되고 있는 디지털 고문헌의 Data Base는 목록정보 DB 목차와 해제정보 DB 전문정보 DB로 구분할 수 있으며, 국내외 자료를 포함하고 있다. 그 수량은 본문의 서술과 같다. (3) 디지털 고문헌의 유형은 고서 고문서 Micro 책판 등을 포함하고 있다 (4) 디지털 고문헌 DB의 입력 방법은 Text Image PDF 형태 등이다. (5) 고문헌의 연합조직을 구축하여 중복 투자를 피하고 봉사 효율을 높이고 있다. 고문헌의 이상적인 디지털화를 위하여 갖추어야 할 점을 제안하면 다음과 같다. (1) 우선 고문헌 디지털화 업무의 통정기구를 조직하여, 일정한 수준의 권한을 부여하고 종합적 계획을 수립한 후 추진하여야 한다. (2) 장단기 계획을 세워서 여러 디지털화 업무의 성격을 분석하고, 점진적으로 추진하여야 한다 (3) 고문헌 자료의 전문가를 양성하여 DB를 구축하고 관리하여야 한다.

  • To develop a sustained-release preparation containing ketorolac tromethamine, two sustained-release pellet formulations were evaluated with a pharmacokinetic study as compared with a conventional commercial tablets (10 mg $Tarasyn^{TM}$, Roche Korea Ltd.). Two sustained-release formulations were as follows; formulation A was composed of an inner layer containing 75% of drug coated with $Eudragit^{TM}$ RS 100 membrane and an outer layer containing 25% of drug mixed with $Eudragit^{TM}$ NE30D, and formulation B was composed of only an inner layer containing 100% of drug coated with $Eudragit^{TM}$ RS 100 membrane. The dissolution test was performed for two formulations. In case of conventional tablets, 2.5 mg of drug per a dose was administered orally into male Albino rabbit (2.0-2.3 kg of body weight) 3 times at intervals of 4 hours. In case of two sustained formulations, 7.5 mg of drug was administered once orally. Blood samples were withdrawn periodically after the administration, and the blood concentration was determined by HPLC. The conventional tablets showed very high peak-trough fluctuation between administered doses, but two sustained formulations showed less fluctuation. Formulation A with the loading dose showed the time to reach minimum effective concentration (MEC) i.e. the onset time was less than 20 min, while Formulation B had more than 1 hr of the onset time. Formulation A had the more constant plasma level than formulation B. However, formulation B had a time lag, so the plasma level was less than MEC for an initial period of 1 hr. In formulation A, the plasma level was maintained within the therapeutic window $(0.3-5\;{\mu}g/ml)$ for a long period. Formulation A was thought to be an ideal sustained-release formulation for ketorolac tromethamine oral delivery system.

  • Two experiments were conducted to determine the standardized ileal digestible (SID) lysine (Lys) requirement and the ideal SID threonine (Thr) to Lys ratio for finishing barrows. In Exp. 1, 120 barrows with an average body weight of $72.8{\pm}3.6$ kg were allotted to one of six dietary treatments in a randomized complete block design conducted for 35 d. Each diet was fed to five pens of pigs containing four barrows. A normal crude protein (CP) diet providing 15.3% CP and 0.71% SID Lys and five low CP diets providing 12% CP with SID Lys concentrations of 0.51, 0.61, 0.71, 0.81 and 0.91% were formulated. Increasing the SID Lys content of the diet resulted in an increase in weight gain (linear effect p = 0.04 and quadratic effect p = 0.08) and an improvement in feed conversion ratio (FCR) (linear effect p = 0.02 and quadratic effect p = 0.02). For weight gain and FCR, the estimated SID Lys requirement of finishing barrows were 0.71 and 0.71% (linear broken-line analysis), 0.79 and 0.78% (quadratic analysis), respectively. Exp. 2 was a 26 d dose-response study using SID Thr to Lys ratios of 0.56, 0.61, 0.67, 0.72 and 0.77. A total of 138 barrows weighing $72.5{\pm}4.4$ kg were randomly allotted to receive one of the five diets. All diets were formulated to contain 0.61% SID Lys (10.5% CP), which is slightly lower than the pig's requirement. Weight gain was quadratically (p = 0.03) affected by SID Thr to Lys ratio while FCR was linearly improved (p = 0.02). The SID Thr to Lys ratios for maximal weight gain and minimal FCR and serum urea nitrogen (SUN) were 0.67, 0.71 and 0.64 using a linear broken-line model and 0.68, 0.78 and 0.70 using a quadratic model, respectively. Based on the estimates obtained from the broken-line and quadratic analysis, we concluded that the dietary SID Lys requirement for both maximum weight gain and minimum FCR was 0.75%, and an optimum SID Thr to Lys ratio was 0.68 to maximize weight gain, 0.75 to optimize FCR and 0.67 to minimize SUN for finishing barrows.

  • The present study was to investigate the nutritional status and factors related to malnutrition in end-stage renal disease (ESRD) patients requiring hemodialysis (HD) in South Korea. Subjects were ESRD outpatients from general hospitals or HD centers in Seoul referred to the dialysis clinic for maintenance HD care. A total of 110 patients (46 men and 64 women; mean ages $58.6{\pm}1.0y$) were eligible for this study. The family history of chronic renal failure (CRF) was considered positive if a patient reported having either a first-degree or second-degree relative with CRF. Malnutrition was defined as a triceps skinfold thickness or mid-ann muscle circumference below the fifth percentile for age and sex and forty-seven of the 110 patients were malnourished. Almost all (94%) patients had anemia (hemoglobin: <13 g/dL for men and <12 g/dL for women). Energy intake was below the recommended intake levels of energy [30-35 kcal/kg ideal body weight (IBW)] and protein (1.2 g/kg IBW) in 60% of patients. The duration of HD was longer in malnourished HD patients (P=0.0095). Malnutrition was more prevalent in women (P=0.0014), those who never smoked (P=0.0007), nondiabetic patients (P=0.0113), and patients with bone diseases (P=0.0427), adequate HD (spKt/$V{\geq}1.2$) (P=0.0178), and those with a family history of CRF (P=0.0255). Multiple logistic regression was used to examine the relationship between malnutrition and potential risk factors. After adjusting for age, sex, and other putative risk factors for malnutrition, the OR for malnutrition was greater in HD patients with a family history of CRF (OR, 3.290; 95% CI, $1.003{sim}10.793$). Active nutrition monitoring is needed to improve the nutritional status of HD patients. A family history of CRF may be an independent risk factor for malnutrition in Korean HD patients. A follow-up study is needed to investigate whether there is a causal relationship between a family history of CRF and malnutrition in Korean ESRD patients.

  • Objectives : We recently have reported that constituents of OMC-2010 have an immuno-modulatory effects via inhibiting tumor necrosis factor (TNF)-alpha and interleukin (IL)-5. In this study, based on previous data, we investigated the effects of combinations with each OMC constituents on splenocyte cytotoxicity, cytokine productions, and ovalbumin (OVA) induced experimental allergic asthma. Methods : Mouse splenocytes were pre-treated with ethanol extract of constituents of Rehmannia glutinosa (RG), Pinellia ternata (PT), Schisandra chinensis (SC). We made 4 combinations using RG, PT, and SC (A;1:1:1, B;2:1:1, C;1:2:1, D;1:1:2). The cells were pretreated with A, B, C, or D for 1 h, then stimulated with lipopolysaccharide (LPS, $1{\mu}g/ml$) for 48 h. Then the cells were harvested for real-time reverse transcription polymerase chain reaction to detect cytokine productions. Then using effective combination from RG, PR and SC, we administrated the combination orally, then challenged with OVA to induce asthma. Then we analyzed the airway hyper-reactivity (AHR), lung histology and lung TNF-${\alpha}$ and IL-5 mRNA. Results : A. B. C. and D did not showed significant cytotoxicity on splenocytes. Pre-treatment of A inhibited the expression of TNF-${\alpha}$ and IL-5 significantly, but not B, C, and D. In experimental asthma, administration of A significantly inhibited the increase of AHR, lung damage, TNF-${\alpha}$ and IL-5 expression. Conclusions : Theses results could suggest that inhibitory effects of the ideal combination with RG, PT and SC (1:1:1) could be applied to treatment of asthma and study of asthma mechanisms.

  • 녹차는 생리활성의 촉진작용뿐아니라 항암, 항산화, 고혈압 억제효과, 체중조절 등 다방면의 약리효과를 보이는 것으로 보고되고 있다. 아울러, 녹차의 항균 및 항진균 작용에 관한 연구결과도 발표되고 있으나, 항균작용 기작에 접근한 기초 연구는 별로 많지 않다. 본 연구는 식품변패미생물에 대한 녹차추출물의 항균작용을 구명하는 기초자료를 획득하는데 그 목적이 있다. 녹차추출물의 항균력을 조사한 결과, $500{\mu}g/mL$ 이상의 농도에서 뚜렷한 항균활성을 보였고, 광역의 병원성 및 부패성 미생물들에 대하여 항균활성을 나타내었다. 또한, 녹차추출물의 항균물질은 넓은 범위의 온도($40{\sim}150^{\circ}C$) 및 pH($3{\sim}11$)에서 안정성을 나타냈다. 따라서 녹차추출물의 항균물질은 항균활성이 높고, 항균 대상 미생물의 분야가 광범위할 뿐아니라, 넓은 범위의 온도 및 pH에 안정하여 이상적인 천연 항균제로서의 개발가능성을 제시하였다. 아울러, 녹차추출물의 항균작용을 알기 위하여, 녹차추출물 처리가 미생물 세포막 기능에 미치는 영향을 조사한 결과, 녹차추출물의 주요 작용기작은 세포막 perturbation에 기인한 것으로 사료되었다.
