Introduction: Placenta previa is a condition in which the placenta implants in the poorly vascularized lower uterine segment, which may result in inadequate uteroplacental perfusion, in turn, adversely affect the neonatal outcome. Abnormal placentation may also lead to severe postpartum hemorrhage as placenta separation proceeds. We aimed to evaluate the differences in placental histopathology and perinatal outcomes in pregnancies complicated with placenta previa and controls. Methods: We undertook a retrospective case-control study of 93 pregnancies with placenta previa and 81 controls between 2011 and 2017. Results: Gross findings of the placenta showed that the placentas in placenta previa had significantly higher mean large chorionic plate diameters (18.5 ± 3.2 vs 17.5 ± 2.6 cm, P = .0298), chorionic plate areas (218.4 ± 62.9 cm2 vs 198.7 ± 56.0 cm2, P = .0344), and marginal cord insertion (19.8% vs 8.6%, P = .0411) than control groups. Placental histopathological findings showed that placentas in placenta previa was significantly associated with maternal underperfusion, including villous infarction (50.5% vs 25.9%, P = .0009) and increased intervillous fibrin deposition (38.7% vs 7.4%, P < .0001). Also, women in the placenta previa group had a higher rate of abnormally invasive placenta and severe postpartum hemorrhage. However, placenta previa was not associated with the increased risk of neonatal mortality and morbidity. Conclusion: Abnormal placentation into the poorly vascularized lower uterine segment induces compensatory placental growth and increased surface area in response to reduced placental perfusion, which was consistent with the histopathological findings of coagulative necrosis of chorionic villi and fibrin deposition in the intervillous space. The morphological changes occurring in placenta previa may have important roles in maintaining adequate uteroplacental-fetal perfusion, which may prevent adverse neonatal outcomes.

연구배경: COPD에서 보이는 호흡곤란의 주된 원인이 폐의 과팽창이고 이 과팽창을 치료하는 것이 호흡곤란의 향상에 중요한 것으로 밝혀지고 있다. 그러나 FEV1, FVC만으로는 호흡곤란의 정도와 과팽창을 정확히 측정할 수 없다. 따라서 단순 흉부 방사선에서 관찰되는 폐의 과팽창의 정도와 고해상도흉부 단층촬영에서 폐기종의 정도가 호흡곤란을 객관적으로 알 수 있는 지표가 되는 지를 알아보고자 하였다. 방법: COPD로 진단 받은 50명(평균 연령 69세, 남자 47명, 여자 3명)을 대상으로 하였다. 폐의 종축, 흉골 뒤 공간, 횡격막의 높이를 각각 측정하여 총 0에서부터 3까지로 폐의 과팽창 정도(chest score)를 측정하였고, 고해상도 흉부단층 촬영에서 폐기종의 정도(HRCT score)를 구하여 이를 환자의 호흡곤란의 정도 및 폐용적 검사를 비롯한 폐기능 검사와의 상관관계를 구하였다. 결과: 호흡곤란의 지수(Borg scale)는 폐기능 검사의 지표인 FVC, FEV1, FEV1/FVC, RV, RV/TLC, DLCO와 유의한 상관관계가 관찰되었다. Borg scale은 HRCT score와 상관관계가 있었으나, chest score와는 상관관계가 없었다. 그리고 Borg scale은 체질량 지수와 역 상관관계가 있었다. 결론: 고해상도 흉부 단층촬영의 폐기종의 정도는 COPD 환자에서 호흡곤란의 정도를 알 수 있는 객관적 지표가 될 수 있다. Background: A lung hyperinflation, or air trapping, caused by expiratory flow-limitation contributes to dyspnea in patients with chronic obstructive pulmonary disease (COPD). Forced expiratory volume in 1 second (FEV1) has served as an important diagnostic measurement of COPD, but does not correlate with patient-centered outcomes such as dyspnea. Therefore, this study was performed to investigate the role of radiologic quantity in evaluating the dyspnea in patients with COPD by measuring lung hyperinflation in chest x-ray and high resolution chest tomography (HRCT). Methods: Fifty patients with COPD were enrolled in this study. Their subjective dyspnea score (modified Borg scale dyspnea index), spirometry, and lung volume were measured. Simultaneous hyperinflations of chest x-ray score (chest score) and degree of emphysema of HRCT (HRCT score) were measured. The chest score were composed of lung length, retrosternal space width, and height of the arc of the diaphragm and HRCT score were composed of severity and extent of emphysema. Results: The mean age of patients was 69 years old and their mean FEV1 was 51.7%. The Borg score significantly correlated with parameters of spirometry and lung volume, including FVC, FEV1, FEV1/FVC, RV, RV/TLC, and DLCO. The Borg score correlated well with HRCT score, but did not correlate with chest score. Also, the Borg scale correlates inversely with body mass index. Conclusion: The quantity of emphysema on chest HRCT may serve as an objective marker of dyspnea in patients with COPD.

정은정(Eun-Jung Chung),김수연(Soo-Yeon Kim),남영주(Young-Ju Nam),박정화(Jung-Hwa Park),황혜진(Hye-Jin Hwang),이양자(Yang-Cha Lee-Kim) 한국식품영양과학회 2005 한국식품영양과학회지 Vol.34 No.8

녹즙분말과 콜레스테롤 첨가식이로 8주간 사육한 흰쥐의 혈중 지질, 호모시스테인 및 엽산수준에 미치는 효과를 관찰한 결과는 다음과 같다. 흰쥐의 혈중 총 콜레스테롤 농도는 녹즙이나 콜레스테롤 보충에 의해 유의한 영향을 받지 않았으나 중성지질 농도는 녹즙군에서 낮았다(p<0.001). HDL-콜레스테롤과 LDL-콜레스테롤의 경우, 식이 콜레스테롤의 영향을 받아, HDL-콜레스테롤은 콜레스테롤군보다 무콜레스테롤군에서 높았으며(p<0.001), LDL-콜레스테롤은 콜레스테롤군에서 높았다(p<0.05). HDL-콜레스테롤 수준은 녹즙군에서 높았으며(p<0.05), LDL-콜레스테롤 농도는 콜레스테롤과 케일의 상호효과가 나타나 무콜레스테롤군에서만 녹즙에 의한 감소효과를 보였다. HDL/LDL 비율은 콜레스테롤 보충군에서 낮았으며(p<0.05), 녹즙보충군에서 높았으나 통계적으로 유의한 결과를 나타내지 못하였다. 혈청 엽산, 비타민 B₁₂ 및 혈장 호모시스테인 농도는 녹즙분말이나 콜레스테롤 보충에 의해 영향을 받지 않았다. 혈중 엽산과 비타민 B₁₂ 농도사이에는 유의한 양의 상관성(r=0.5632, p< 0.001)이 관찰되었으나, 혈중 호모시스테인 농도는 혈중 엽산, 비타민 B₁₂ 및 콜레스테롤 농도 사이에는 모두 유의한 상관성이 관찰되지 않았다. 본 연구결과를 종합하여 보면, 엽산이 충분히 공급되는 경우, 녹즙보충시 나타나게 되는 심혈관계질환 예방효과는, HDL 농도의 증가 및 중성지방 농도의 감소에 의한 것이며, 녹즙내 엽산보충에 의한 호모시스테인 농도 변화와는 관련이 적은 것으로 사료된다. The purpose of this study was to investigate the effects of green vegetable (kale) juice powder supplementation on lipid profiles, plasma homocysteine, folate and vitamin B₁₂ in rats fed cholesterol (Chol.) or Chol. free diet. 7-week old male Sprague Dawley rats (n=40) were divided into 4 groups, and experimental diets containing control diet group (CO), control diet plus 0.5 wt% Chol. (CC), control diet added with 5 wt% kale (KO), control diet added with 5 wt% kale plus 0.5 wt% Chol. (KC) were fed for 8 wks. Plasma homocysteine level was examined by amino acid analyzer and serum folate and vitamin B₁₂ level were measured by competitive radioimmunoassay methods. In various serum lipid profiles, TG level was lower in kale juice powder groups (KO, KC) compared to the corresponding groups (CO, CC) (p<0.001). In Chol. supplemented groups (CC, KC), HDL-Chol. level was lower (p<0.001) and LDL-Chol. level was higher (p<0.05) than Chol. free diet. HDL-Chol. level was higer (p<0.05) in kale juice powder groups. HDL/LDL ratio was lower in Chol. supplemented groups (CC, KC) and tended to be higher in kale juice powder groups (KO, KC). Serum folate and vitamin B₁₂ levels were not affected by dietary Chol. and kale juice powder supplementation. Plasma homocysteine level was not affected by dietary Chol. and kale juice powder supplementation, too. Serum folate level was positively correlated with serum vitamin B₁₂ level (r=0.5632, p<0.001), but plasma homocysteine level was not significantly correlated with any serum folate, vitamin B₁₂ and Chol. levels, respectively. In summary, kale juice powder supplementation have improved serum lipid profiles by increasing the HDL level and decreasing the TG level and have not altered homocysteine level under the sufficient supply of folate and vitamin B complex relating with the homocysteine metabolism.

This study attempted to provide implications for the design of an effective nail service marketing program after analyzing nail service users’ characteristics and the effects of appearance-related attitude andsocio-psychological traits on nail service use patterns. Regarding nail salon preference attributes, the group of ‘appearance orientation’ was greater than the group of ‘price’ with statistical significance among appearance-related attitudes in the group of ‘quality of service’. In the group for which a downtown area was chosen as the preferred location of a nail salon, appearance conformity, desire to show off and self-esteem showed statistical significance in appearance-related attitudes and socio-psychological traits. In terms of the factors affecting use frequency and costs with statistical significance, expenses were higher among singles and those with high monthly household income. In addition, the expenses further increased as achievement desire was weaker, and a desire to show off was stronger. User satisfaction was higher as the perception of appearance values increased among appearance-related attitudes. The said results show that for effective nail service marketing, it is necessary to clarify the target group and provide customized services after analyzing target customers’ socio-psychological traits.
