Apgar score is most widely used evaluating indicator of newborn health, but it is very Subjective. Umbilical cord blood gas analysis is more objective and effective than Apgar score in evaluation of newborn status. Cord blood gas was changed slightly by processing of time after fetal birth. This study was undertaken to observe objectiveness and effectiveness of umbilical arterial blood gas analysis and effects of time interval of cord clamping to newborn health with 122 pregnant women and their babies. We observed following results : 1. There were poor correlation between Apgar score and umbilical cord arterial blood analysis in evaluating of newborn health (P>0.05). 2. There was no clinical significance of Apgar score or umbilical arterial blood gas analysis as single indicator in evaluating of newborn health (P>0.05). 3. Gas analysis and pH of umbilical arterial blood was more helpful in evaluating of newborn health than Apgasr score. 4. There were no significant effects of time interval of umbilical cord clamping to newborn health. 5. If there were no indications of early umbilical cord clamping, cord blood sampling at immediately after birth without cord clamping was more effective to evaluate newborn status.

Neonatal coagulation disorders and thromboembolism require timely management. Failure to treat these conditions at the appropriate time may lead to death or the development of significant long-term sequelae. However, most current guidelines for managing neonatal coagulation disorders and thromboembolism are empiric and not based on randomized clinical trials. Thus, it is not easy to choose an appropriate management strategy for these conditions in clinical settings. In this review, therapeutic guidelines currently utilized in clinics and novel therapeutic options still under investigation are presented and reviewed.

To evaluate the effects of pregnancy-induced hypertension (PIH) to the iron status of fetuses, umbilical cord blood of 35 newborn infants borne by PIH mothers and of 37 normal term infants delivered at Yeungnam University Hospital from September 1, 1993 to September 30, 1994, were studied. The serum hemoglobin concentration of women with PIH was significantly higher than normal full-term pregnant women. There was no significant difference in serum hemoglobin concetration between women with PIH and normal full-term pregnant women and their newborn infants. There was no significant difference in serum hemoglobin concentration beween infants of women with PIH and normal full-term infants. The serum iron concentration of newborn infants of women with PIH was higher and the serum ferritin concentration of newborn infants of women with PIH was lower than normal full-term infants, but there were no significant difference between the two groups. The serum total iron-binding capactity and unsaturated iron-binding capacity of infants of women with PIH were significantly higher than normal full-term infants. The newborn infants of PIH women seemed that they might have occult depletion of iron store and need meticulous follow up during early neonatal period.

목적 : 한의학 분야에서 육계(CCE: Cinnamomum cassia)는 혈류 순환이 저하된 상태에 널리 쓰이는 약재이다. 이 연구에서는 CCE와 그 활성 혼합물인 cinnamic acid가 in vitro와 in vivo에서 발휘하는 신생혈관 형성 작용에 대해 알아보고자 한다. 방법 : CCE와 CA의 신생혈관형성 작용을 알아보기 위하여 Human unbilical endothelial cells(HUVECs)와 Bovine arterial endothelial cells(BAECs) 그리고 Matrigel assay를 이용하였다. 결과 : In vitro에서 CCE와 그 활성 혼합물은 HUVEC 증식, 이동, 모세혈관-유사 관 형성을 유도한다. CCE에서의 25-50% 증가(1 또는 10ng/ml 용량에서)는 CA에서 증식과 유사하게 나타났다. HUVEC에서는 증식이 뚜렷하게 나타났으나 BAEC에서는 증식이 뚜렷하게 나타나지 않아 증식 효과는 내피세포의 기원에 따라 다른 것으로 나타났다. BAEC는 CCE와 CA에서 증식은 보이지 않았지만 이동과 모세혈관-유사 관 형성 또는 분화를 보였다. 또한 CCE와 CA는 HUVEC에서 VEGF 발현과 Flk-1/KDR 발현을 각각 2.2배와 2.5배 증가시켰다. 결론 : CCE와 그 활성 혼합물은 in vivo와 in vitro에서 혈관 내피세포의 VEGF 발현을 통하여 신생혈관 형성 작용을 유도하며 이는 앞으로 다른 한약 추출물의 신생혈관형성 촉진 작용 연구에 모델을 제시할 것으로 보인다.

Purpose : We aimed to examine the effect of rooming-in care on newborn infants emotional stability by comparing them with those cared for in a nursery. Methods : Forty-eight full-term newborn infants born at Cheil General Hospital between July 1 and October 31, 2007, were enrolled. Twenty-four newborn infants were roomed-in in their mothers rooms (rooming-in group), and 24 newborns were cared for in the hospital nursery (the nursery group) for the first 3 days of their lives. Those with perinatal problems that required medical treatment were excluded. By using Brazeltons neonatal behavior assessment scale, we measured irritability and self-quieting as well as the duration of crying after heel-stick puncture for the newborn metabolic screening test. Results : The rooming-in group had a higher irritability score than the nursery group ($6.8{\pm}1.7$ vs. $4.2{\pm}2.1$, P<0.001), thereby suggesting stable behavior against external irritation; the former also had a higher self-quieting activity score ($5.9{\pm}0.3$ vs. $4.5{\pm}1.8$, P=0.001), thereby suggesting that stability was reached quickly from the irritated state. Time taken to stop crying after the heel-stick puncture was significantly shorter in the rooming-in group than in the nursery group ($17{\pm}15.1$ seconds vs. $115.3{\pm}98.5$ seconds, P<0.001). Conclusion : These results show that newborn infants in the rooming-in group exhibit more stable behavior against external irritation and can be stabilized from an irritated state more quickly than infants cared for in the nursery, even after a few days of rooming-in care.

For the extended duration of the coronavirus disease 2019 (COVID-19) pandemic, reports emerged that mother-to-child transmission rates were low. However, the pandemic protocols including strict isolation, testing for severe acute respiratory syndrome coronavirus 2, and negative pressure isolation remained in Korea. Recently, the guideline for the management of neonates born to mothers with COVID-19 have been revised based on guidelines in other countries. Here, we introduce this newly developed guideline and review the foreign guidelines that were used for reference.

Purpose : The relationship between chest X-ray findings and respiratory indices, including the arterial-alveolar oxygen partial pressure ratio($a/APO_2$) and the ventilatory index(VI), indicators of the clinical respiratory status in neonates with respiratory distress syndrome(RDS), was examined in the present study. Methods : The records of 50 neonates, randomly chosen from 174 neonates treated with pulmonary surfactant(PS) in the Neonatal Intensive Care Unit of Kyunghee University Hospital from 1996 to 2000 were analyzed retrospectively. Chest radiographs taken at the time after birth were classified into four groups according to Bomsel's classification. The $a/APO_2$ and VI values were calculated and compared with the corresponding chest radiographs. Results : Among the 50 cases of RDS examined, three cases were classified into grade I(6%), eight cases into grade II(16%), 20 cases into grade III(40%), and 19 cases into grade IV(38%). The mean $a/APO_2$ of the cases classified into grades I or II was 0.32 and the mean $a/APO_2$ of those classified into grades III and IV was 0.18 and 0.09, respectively. The mean VI was 0.049 for the cases classified into grades I or II and 0.076 and 0.161 for those classified into grades III and IV, respectively. Conclusion : The severity of RDS according to chest X-ray findings correlate to the values of respiratory indices, $a/APO_2$ and VI.

Purpose: The purpose of this study was to compare the neonatal birth weight, birth height, Apgar scores, sucking power, and digestion difficulties between smoking and non-smoking women following cesarean birth. This study analyzed the effects of smoking on the neonatal health status in pregnant women to provide fundamental data for smoking prevention education for women of childbearing ages and non-smoking practice protocols for pregnant women with smoking. Methods: A comparative survey design was used. Fifty-four newborn infants of pregnant women with smoking and seventy-four newborn infants of pregnant women with non-smoking participated in this study. The scores of neonatal birth weight, birth height, Apgar scores, sucking power, and digestion difficulties were assessed. Data were analyzed using SPSS Windows 15.0 program. Results: Smoking in pregnant women leads to the decrease of birth weight (F=4.75, p=.030) and birth height (F=14.19, p<.001), negative effects on the Apgar scores (F=36.02, p<.001) and sucking power (t=-4.26~-5.60, p<.001), and digestion difficulties ($x^2$=6.72, p=.010) of neonates. Conclusions: This study demonstrated that smoking in pregnant women leads to the decrease of fetus development. These findings would be utilized for the development of not only smoking prevention programs for women of childbearing ages but also prenatal education programs for pregnant women.

The current study is the first paper on FPT(failure of passive transfer) of horse population in Korea. The object of this study was to comparison of immune status normal and patient horses. Failure of passive transfer is the most common immunodeficiency disorder of horses. Twenty-two foals and 18 horses from Jeju of the equine hospital were diagnosed with the SNAP Foal IgG Test Kit. All adult horses had normal immune functions (≥800 mg/dl). Thirteen of the 22 newborn babies (59%; ∠800 mg/dl) had a weak immune function but recovered and survived after treatment. Nine of these 22 are horses with strong immunity (≥800 mg/dl), indicating that high IgG concentrations in the blood can cause infectious diseases. There were a total of six dead, four of which were infectious diseases. In addition, early identification of infectious diseases in newborn foals is expected to help prepare systematic health management measures for the development of the disease.

Invasive infection of the Streptococcus bovis group in a neonate is rare. In cases reported to date, the pathogen of neonatal S. bovis infections is usually Streptococcus gallolyticus subsp. pasteurianus (S. bovis biotype II/2). Streptococcus lutetiensis (S. bovis biotype II/1) was identified using 16S rRNA and tuf gene sequence analysis of the isolates from blood and cerebrospinal fluid (CSF) of a fever-presenting 28-day-old male. Blood culture analysis was performed using automatic equipment (VITEK 2) and identified Streptococcus infantarius supsp. infantarius, yet we were unable to get accurate results from the CSF culture. The fever subsided on the second day of hospitalization, and the patient was discharged without neurologic complication after 14 days of antibiotic therapy. In this case, we were able to accurately identify the pathogen using molecular genetic methods. To our knowledge, this is the first case of late onset neonatal bacteremia and meningitis caused by S. lutetiensis.
