Background: While the perinatal outcomes of active maternal smoking are well documented, results of the effects of environmental tobacco smoke (ETS) exposure during pregnancy are inconsistent. We aimed to examine the effect of ETS exposure, assessed by maternal hair nicotine levels at $35^{th}$ week of gestation, on birth weight and the risk of small for gestational age (SGA) and low birth weight (LBW). Materials and Methods: A total of 871 non-smoking healthy pregnant women were recruited by one Korean hospital between 1 October 2006 and 31 July 2007. Hair samples were collected and anthropometric questionnaires administered at $35^{th}$ week of gestation. The primary outcome was birth weight and secondary outcomes were the risk of babies being SGA and LBW. Results: Log-transformed hair nicotine concentrations were inversely related with birth weight after adjusting for confounding variables (${\beta}=-0.077$, p=0.037). After stratifying hair nicotine levels by tertiles (T1, low [0.0-0.28 ng/mg]; T2, medium [0.29-0.62 ng/mg]; and T3, high [0.63-5.99 ng/mg]), the mean birth weight in each groups were 3,342g (T1) 3,296g (T2) and 3,290 g (T3), respectively. However the difference between groups was not statistically significant by analysis of co-variance (ANCOVA) adjusting for covariates (p=0.062). In logistic regression analysis, the risk of SGA was higher in the T3 (OR=1.59, 95%CI 1.05-2.42) than in the reference group (T1), after controlling for confounding variables. The risk of low birth weight (<2,500g, LBW) was not significantly higher (OR=1.44, 95%CI 0.95-2.19), but the risk of babies being below 3,000g birth weight was increased in the T3 group (OR=1.53, 95%CI 1.00-2.36) compared with that in the T1 group. Conclusions: Maternal ETS exposure during pregnancy was inversely related with birth weight. The risk of SGA increased in the highest ETS exposure group compared with in the low exposure group. To prevent ETS exposure during pregnancy, more comprehensive tobacco control policies are needed.

Extract of Lentinula edodes mycelia (LEM) is currently utilized as an oral biological response modifier (BRM) medicine for cancer patients. However, its effectiveness for breast cancer patients with postoperative adjuvant hormone therapy has not yet been scientifically verified. In this study, we investigated the influence of LEM on the quality of life (QOL) and immune response in breast cancer patients undergoing postoperative adjuvant hormone therapy. Twenty patients were studied in total. They received only hormone therapy in the first 4 weeks followed by hormone therapy and LEM during the next 8 weeks. Laboratory tests, QOL score and peripheral blood cytokine production levels were evaluated during the study period. No changes in QOL or cytokines were noted after the first 4 weeks. In contrast, during the following combined therapy period, improvements were noted in QOL and cytokine levels. Although a future large-scale investigation is necessary to confirm these results, these data suggest that the concomitant use of LEM with postoperative adjuvant hormone therapy improves the QOL and immune function of patients.

The occurrence of functional gastrointestinal disorders (FGIDs) is a formidable challenge for infants, parents, and healthcare professionals. Although data from the Middle East are scarce, experts consider FGIDs a prevalent condition in everyday clinical practice. The new Rome IV criteria revisited the definitions from a clinical perspective to provide a practical and consistent diagnostic protocol for FGIDs. However, the treatment practices for functional disorders vary considerably among Middle Eastern countries, often resulting in mismanagement with unnecessary investigations and treatments. In addition, the role of various treatment modalities, including probiotics such as Lactobacillus reuteri DSM 17938, in FGIDs requires further discussion and evaluation. During a consensus meeting, a locally relevant approach for treating common FGIDs such as infant regurgitation, infant colic, and functional constipation was discussed and approved by regional experts. The participants suggested a simplified treatment plan and protocol for general pediatricians and other primary care physicians managing FGIDs. This easy-to-follow standardized protocol will help streamline the initial management of this complex disorder in the Middle East region and even globally.

Intraventricular hemorrhage (IVH) is a serious concern for preterm infants and can predispose such infants to brain injury and poor neurodevelopmental outcomes. IVH is particularly common in preterm infants. Although advances in obstetric management and neonatal care have led to a lower mortality rate for preterm infants with IVH, the IVH-related morbidity rate in this population remains high. Therefore, the present review investigated the pathophysiology of IVH and the evidence related to interventions for prevention. The analysis of the pathophysiology of IVH was conducted with a focus on the factors associated with cerebral hemodynamics, vulnerabilities in the structure of cerebral vessels, and host or genetic predisposing factors. The findings presented in the literature indicate that fluctuations in cerebral blood flow, the presence of hemodynamic significant patent ductus arteriosus, arterial carbon dioxide tension, and impaired cerebral venous drainage; a vulnerable or fragile capillary network; and a genetic variant associated with a mechanism underlying IVH development may lead to preterm infants developing IVH. Therefore, strategies focused on antenatal management, such as routine corticosteroid administration and magnesium sulfate use; perinatal management, such as maternal transfer to a specialized center; and postnatal management, including pharmacological agent administration and circulatory management involving prevention of extreme blood pressure, hemodynamic significant patent ductus arteriosus management, and optimization of cardiac function, can lower the likelihood of IVH development in preterm infants. Incorporating neuroprotective care bundles into routine care for such infants may also reduce the likelihood of IVH development. The findings regarding the pathogenesis of IVH further indicate that cerebrovascular status and systemic hemodynamic changes must be analyzed and monitored in preterm infants and that individualized management strategies must be developed with consideration of the risk factors for and physiological status of each preterm infant.

This study was carried out to assess the problems with the pregnant women, and check out the risk-factors in the high-risk pregnancies, using a simplified antepartum risk-scoring system, which was revised from Edwards' scoring system to be suitable for Korean situaition. This instrument was included 4 categories, demographic, obstetric, medical and miscellaneous factors. This survey was based on the 1300 pregnant women who were admitted, $x^2$-test, F-test, Pearsons correation, using statistical package SAS in NAS computer system, KIST. The results of the study were as follows; 1. 1313 infants were deliveried of these 560 infants(42.7%) were born to mothers with risk-scores > 7, and 753 infants(57.3%) were born to mothers risk-scores <7. 2. Maternal age" parity, education level, of the demographic factors were significant relation statistically to identify the high risk pregnancies($X^2$=20.88, 42.87, 15.60 P < 0.01). 3. C-section, post term, incompetent cervix, uterine anomaly, polyhydramnios, congenital anomaly, sensitized RH negative, abortion, preeclampsia, excessive size infant, premature, low birth weight infanl, abnormal presentation, perinatal loss, multiple pregnancy, of the obstetric factors were significant relation statistically to identify the high risk-pregnancies. ($X^2$ = 175.96, 87.5, 16.28, 21.78, 9.46, 8. 10, 6.75, 22.9, 64.84, 6.93, 361.43, 185.55, 78.65, 45.52, P < 0.01). 4. Abnormal nutrition, anemia, UTI, other medicalcondition(pulmonary disease, severe influenza), heart disease, V.D., of the miscellaneous and medical factors, were significant relation statistically to identify the high risk-pregnancies. 5. Premature, low birth weight infant, contracted pelvis, abnormal presentation, of the risk factors were significantly related with Apgar score at 1 '||'&'||' 5 minute after birth and neonatal body weight. 6. Apgar score at 1 '||'&'||' 5 minute after, birth and neonatal body weight were significantly negative correlated with risk-score. 7. There were statistically significant difference between risk-score and Apgar score at 1 '||'&'||' 5 minute after birth, 3 group(0-3, 4-6, above 7), and neonatal body weight, 2 group(below 2.5kg, the other group) (F=104.65, 96.61, 284.92, P<0.01). 8. Apgar score at 1 '||'&'||' 5 minute after birth(below 7), and neonatal body weight(below 2.5kg), were significant relation statistically with risk score.($x^2$=65.99, 60.88, 177.07, P<0.01) were 60.8 %, 60% . 9. Correct classifications of morbid infants(l '||'&'||' 5 minute Apgar score < 7) were 77.8%, 83.8% and that of nonmorbid infants(l '||'&'||' 5 minute Apgar score > 7) were 60.8%, 60%. 10. There were statistically significant difference between dislribution of maternal risk-score among the morbid infants(l '||'&'||' 5 minute Apgar score < 7) and non morbid infants(l '||'&'||' 5 minute Apgar score> 7) ($x^2$=64.8, 58.8, P < 0.001). 11. There were statistically significant difference between distribution of morbid infants(l '||'&'||' 5 minute Apgar score < 7) and fetal death. 12. The predictivity for classifying high.risk cases was 12 % and for classifying low-risk cases was 98.3 % in 5 minute Apgar score. Suggestions for further studies are as follows; 1. Contineous prospective studies, using this newly revised scoring system are strongly recommended in the stetric service. 2. Besides risk facto~s used in this study, assessmenl of risks by factors in another scoring system and paralled studies related to perinatal outcome are strongly recommended.

The need of oriental nursing role is recently increasing. The implication of this trend is enormous not only for the need of independent of independent oriental nursing intervention. Hence, this study was designed to describe the characteristics of oriental nursing activity and identify the meaning of nursing activity in oriental hospital. A total of 24 nurses were selected by convenience sampling from eight units at one oriental hospital. A total of 168 data were collected using minute-by-minute recording during nurse s work shift. The data were analyzed using nova and scheffe method as post-hoc test The results of this study are as follows; 1. the category of nursing activity in oriental hospital 74.4% of nursing activity was the patient-oriented nursing care. The nursing activity included others (18.28%), the function-oriented nursing care (7.07%), and staff-oriented care (0.2%). 29.1 % of the patient-oriented nursing care was the direct care, and 24. 5 % of the patient-oriented nursing care was the indirect care. There was a lack of patient education and the communication patient. 2. Nursing activity in oriental hospital by characteristics 1) Nursing activity by unit For patient-oriented nursing care, there was a statistically significant difference among 8 units. In the critical care unit, the patient-oriented nursing care was mostly performed. For function-oriented nursing care, there was statistically significant difference among 8 units. In the physical therapy unit, the function-oriented nursing care was mostly performed. 2) Nursing activity in oriental hospital For all kinds of nursing activity, there was a statistically significant difference between shifts. In night shift patient-oriented nursing care, function-oriented nursing care, and other kinds of nursing care was mostly performed. Patient-oriented nursing care included indirect care, treatment set management, and the breaktime. In day shift, staff-oriented nursing care was performed. 3) Nursing activity in oriental hospital For all kinds of nursing activity, there was not a statistically significant difference by day. The day has not impact on nursing activity. 3. the meaning of activity in oriental hospital The results of this study show that the patient-oriented care was vital check, input! output check, medication, bedsore prevention, nasogastric feeding, oral care, catheterization care, perinatal care, nursing care associated with acupuncture and moxacautery, observation (fever, sweating), heat and cold application communication with patent and family, and patient room management In conclusion, two issues associated with the findings of the research appeated to be involved in the difficulty of nursing activity in hospital. The first issue was the nursing care in oriental hospital provided by nurses who have a limited understading of the principles of oriental medicine. The second issue was the deficiency of systematic guideling for oriental nursing activity. The findings suggest the need to develop the systematic guideline for oriental nursing activity. The need of continuing education for nurses who work in the oriental hospital, and the need of nursing education including oriental nursing are critical.

A cumulative evidence indicates that consumption of tea catechin, flavan-3-ol derived from green tea leaves, lowers the risk of cardiovascular diseases. However, a precise mechanism for this cardiovascular action has not yet been fully understood. In the present study, we investigated the effects of different green tea catechins, such as epigallocatechin-3 gallate (EGCG), epigallocatechin (EGC), epicatechin-3 gallate (ECG), and epicatechin (EC), on angiotensin II (Ang II)-induced hypertrophy in primary cultured rat aortic vascular smooth muscle cell (VSMC). [$^3H$]-leucine incorporation was used to assess VSMC hypertrophy, protein kinase assay, and western blot analysis were used to assess mitogen-activated protein kinase (MAPK) activity, and RT-PCR was used to assess c-jun or c-fos transcription. Ang II increased [$^3H$]-leucine incorporation into VSMC. However, EGCG and ECG, but not EGC or EC, inhibited [$^3H$]-leucine incorporation increased by Ang II. Ang II increased phosphorylation of c-Jun, extracellular-signal regulated kinase (ERK) 1/2 and p38 MAPK in VSMC, however, EGCG and ECG , but not EGC or EC, attenuated c-Jun phosphorylation increased by Ang II. ERK 1/2 and p38 MAPK phosphorylation induced by Ang II were not affected by any catechins. Ang II increased c-jun and c-fos mRNA expression in VSMC, however, EGCG inhibited c-jun but not c-fos mRNA expression induced by Ang II. ECG, EGC and EC did not affect c-jun or c-fos mRNA expression induced by Ang II. Our findings indicate that the galloyl group in the position 3 of the catechin structure of EGCG or ECG is essential for inhibiting VSMC hypertrophy induced by Ang II via the specific inhibition of JNK signaling pathway, which may explain the beneficial effects of green tea catechin on the pathogenesis of cardiovascular diseases observed in several epidemiological studies.

목 적 : 자간전증은 임신부와 신생아의 사망 및 이환의 주된 원인으로 유전적 소질과 환경적 요인에 의해 발생하는 다요인성 질환이다. ET-1은 강력한 혈관수축 펩티드로 ET-1 시스템 내의 변경이 자간전증에서의 혈관수축을 자극하는 것으로 생각되고 있다. 본 연구에서는 정상 임신부와 자간전증 임신부에서 ET-1 유전자의 4가지 단일염기다형성들(c.1370T>G, c.137_139delinsA, c.3539+2T>C, and c.5665G >T)의 양상을 조사하여 비교함으로써 이러한 유전자 다형성들과 한국인 자간전증의 연관성에 대하여 알아보고자 하였다. 방 법 : 자간전증 임신부 206명과 임신기간 동안 자간전증이 발생하지 않은 정상 임신부 216명의 혈액으로부터 DNA를 추출하고 ET-1 유전자 다형성들의 양상을 SNapShot kit와 ABI Prism 3100 Genetic analyzer를 사용하여 분석하였다. 결 과 : 자간전증 환자군에서 ET-1 유전자의 4가지 단일 염기다형성 각각의 유전자형 및 대립유전자의 빈도는 대조군과 유의한 차이가 없었다. 또한 자간전증 환자군에서 3가지 일배체형(TDTG, GDCT, and TICT)의 빈도도 대조군과 유의한 차이가 없었다: 61%(TDTG), 13%(GDCT), 13%(TICT) vs. 62%, 14%, 12%. 나이, 미산부률, 분만주수, 신체질량지수 등의 자간전증 발생요인을 공변량으로 하여 유전자형과 자간전증 발생의 위험도 사이의 연관성을 확인하기 위해 다중회귀분석을 시행한 결과 열성모델과 우성모델에서 모두 ET-1 유전자의 단일염기다형성들에 대한 자간전증 발생의 위험도가 증가하지 않았다. 결 론 : 한국인 임신부에서 ET-1 유전자의 4가지 단일염기 다형성들은 자간전증 발생과 연관이 없는 것으로 사료된다.
