윤미자(Mi-Ja Yun),오세인(Se-In Oh),이미숙(Mee Sook Lee) 한국식품영양과학회 2009 한국식품영양과학회지 Vol.38 No.1

식용 및 약용으로 예로부터 널리 이용하는 양송이버섯 추출물의 생리적 기능에 대한 활성을 탐색하기 위하여 양송이 버섯(Agaricus bisporus)의 에탄올 추출물의 항산화 효과와 Ames test를 통한 돌연변이 유발 억제능을 탐색하였다. 지질과산화물에 대한 단백질 보호효과를 알아본 결과, 양송이 버섯 에탄올 추출물은 MDA와 BSA의 교차결합 형성을 100㎎/assay이었을 때 72.21% 저해하였다. Fe²?에 의해 유도된 지질의 과산화에 대한 저해율은 2.0 ㎎/assay일 때 24.96%였으며, DPPH 라디칼 소거 활성을 측정한 결과 1.0 ㎎/assay일 때 52.75%의 저해율을 보였으며 처리농도가 증가할 수록 저해율은 증가하였다. IC?? 값으로 항산화능의 상대적 비교를 하였을 때 양송이버섯 추출물은 DPPH 라디칼 소거활성이 가장 강하였으며, 그 다음은 지질과산화 억제능이었고 MDA와 BSA의 교차결합 억제능이 가장 낮았다. Ames test를 이용하여 돌연변이 유발 억제능을 알아본 결과, 양송이버섯 에탄올 추출물은 Salmonella Typhimurium TA98 및 TA100 두 균주에서 직접작용 돌연변이능을 각각 100% 저해하여 매우 효과적이었다. 간접작용 돌연변이능 저해효과는 Salmonella Typhimurium TA98에서 86.09%, Salmonella Typhimurium TA100에서는 81.93%로 나타나 양송이버섯 에탄올 추출물은 직접, 간접작용 돌연변이능에 대한 저해효과가 우수하다고 사료된다. 본 연구 결과를 종합해 볼 때, 양송이버섯은 항산화성과 항돌연변이성이 우수하므로 기능성식품으로 개발할 수 있는 가능성이 있다고 본다. This study was performed to investigate the antioxidative effects such as the inhibition of malondialdehyde (MDA) and bovine serum albumin (BSA) conjugation reaction, inhibition of Fe²?-induced lipid peroxidation and the scavenging effect on 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical, as well as antimutagenic capacities as Ames test in ethanol extracts of Agaricus bisporus. Agaricus bisporus ethanol extracts inhibited Fe²?-induced lipid peroxidation and scavenged DPPH radical. The IC?? of Agaricus bisporus ethanol extracts were 78.63 ㎎/assay for inhibition of MDA with BSA conjugation reaction, 4.06 mg/ assay for inhibition of Fe²?-induced lipid peroxidation and 1.08 ㎎/assay for scavenging effect on DPPH radical. So, among the methods used in this study, the most effective antioxidative capacity in ethanol extracts of Agaricus bisporus was the scavenging effect on DPPH radical. The indirect and direct antimutagenic effects of ethanol extracts of Agaricus bisporus were examined by Ames test using Salmonella Typhimurium TA98 and TA100. The inhibitory effects on direct mutagenicity mediated by sodium azide in Salmonella Typhimurium TA100 and 2-nitrofluorene in Salmonella Typhimurium TA98 were 100%. The inhibition rates on indirect mutagenicity mediated by 2-anthramine were 86.09% in the Salmonella Typhimurium TA98 and 81.93% in the Salmonella Typhimurium TA100. The ethanol extracts of Agaricus bisporus showed considerable antioxidative activity and strong antimutagenic capacity.

임상연구 : 소아의 편도와 아데노이드 적출술 시 Clonidine 정맥 전투약의 효과

윤미자 ( Mi Ja Yun ) 대한마취과학회 2003 Korean Journal of Anesthesiology Vol.45 No.6

Background: Clonidine, a prototype α₂-adrenoreceptor agonist, has been shown to be effective as a preanesthetic medication in adults. Many authors have reported the effects of intravenous clonidine pretreatment on the hemodynamic responses to tracheal intubation, on the anesthetic requirements during the operation and on postoperative analgesia in adults. The current study was designed to investigate the efficacy of two doses of intravenous clonidine as premedicants. Methods: In a prospective, randomized, double-blind, controlled clinical trial, 60 children, aged 5-12 years, undergoing an elective adenotonsillecctomy received saline, 1 ㎍/㎏ clonidine or 2 ㎍/㎏ clonidine intravenously. These agents were administered 10 minutes before the estimated time of induction of anesthesia with intravenous atropine 0.01 ㎎/㎏. A blinded observer noted the childrens` levels of sedation, the quality of separation from parent, and degree of acceptance of mask application during the inhalation of 100% oxygen just after pentothal sodium injection. Hemodynamic changes after tracheal intubation were compared among the three groups. Results: Clonidine produced significant sedation, and this effect were dose related. The clonidine administered groups provided a better quality of separation than the control group. Amnesia about mask application was significantly higher in the clonidine 2 ㎍/㎏ administered group. These doses of clonidine did not attenuate increases in blood pressure and heart rate after tracheal intubation. No consistent differences in the blood pressure or heart rate after tracheal intubation were observed in the three groups. No clinically significant perioperative hypotension or bradycardia was observed. Conclusions: These data indicate that, the combination of intravenous 1 ㎍/㎏ clonidine or 2 ㎍/㎏ clonidine with atropine 0.01 ㎎/㎏ is an effective form of premedication in pediatric surgery. However, the optimal dose of clonidine for both sedation and hemodynamic stability after tracheal intubation in this setting remains to be determined. (Korean J Anesthesiol 2003; 45: 715∼719)

상호작용놀이 집단상담이 초등학교 아동의 자아존중감과 사회성에 미치는 영향

윤미자 ( Mi Ja Yun ),안경한 ( Kyoung Han An ) 아시아문화학술원 2016 인문사회 21 Vol.7 No.3

본 연구는 상호작용놀이 집단상담이 초등학교 아동의 자아존중감과 사회성 향상에 미치는 효과를 알아보고자 홍천군 소재 초등학교 4학년 147명 아동 중 자발적신청자 중에서 실험집단 13명, 통제집단 13명을 선정, 매주 2회, 60분씩 12회기 진행 한후 결과를 통계적으로 분석하였다. 연구 결과는 다음과 같다. 첫째, 상호작용놀이를 통한집단상담 프로그램은 아동의 자아존중감 향상에 효과가 없는 것으로 나타났다. 둘째, 상호작용놀이를 통한 집단상담 프로그램은 초등 4학년 아동의 사회성 향상에 효과가 있는 것으로 나타났다. 이와 같은 결과는 학교장면에서 아동들의 사회성을 향상시키고자 할 때 상호작용놀이 집단상담을 적용한다면 도움이 된다는 점과 자아존중감을 향상시키고자 할때 프로그램의 타당도와 하위변인의 고른 포함, 자아존중감 향상을 매개하는 변인 연구가 필요함을 시사한다 The purpose of this study is to verify the effects of interaction-playgroup-counseling on elementary school children``s improvement for self-esteem and sociality. For that, there are two hypotheses set in this study. One is that the self-esteem of experimental group taken by interaction-play group-counseling will be improved to the significant standard more than that of control group not taken. The other is that the sociality of experimental group taken by interaction-playgroup-counseling will be improved significantly more than that of control group nottaken. For verifying the hypotheses, the study is conducted for 1 hour per a time, 2times every week and total 12 times, with a supporter, which aims at 26 students participating voluntarily of 147 students who are in 4th grade in elementary schools. They are divided into 2 group, one of which consists of 13 students, an experimental group. The other 13 students consist of a control group. The inspecting tools used in this study are questionnaires measuring self-esteem for which existing researches used. For the data processing analysis, independent sample verification with SPSS Win 12.0 program is used for analyzing the homogeneity and ANCOVA for examining the effects on self-esteem and sociality. The results in this study follows. Firstly, it shows that the interaction-playgroup-counseling program doesn’t have any effects on self-esteem improvement of4th graders in elementary school. Secondly, the interaction-play group-counseling program has partial effects on sociality improvement of 4th graders in elementary school. These results imply that the program used in this study has to be completed and modified to improve self-esteem of children, and that the interaction-playgroup-counseling will be helpful if intending to improve sociality in school life

증례보고 : 상부기관협착증을 가진 환자의 기관절제와 단단문합술에서의 후두마스크를 사용한 마취관리

권태명 ( Tae Myoung Kwon ),윤미자 ( Mi Ja Yun ),강종만 ( Jong Man Kang ),오아영 ( Ah Young Oh ) 대한마취과학회 2006 Korean Journal of Anesthesiology Vol.51 No.4

Tracheotomy and end-to-end anastomosis is a relatively rare operation, but it is one of the most challenging for anesthesiologists. During surgery, the principal anesthetic consideration is to maintain the ventilation and oxygenation throughout the procedure. We experienced anesthetic management of a 49-year-old man with upper tracheal stenosis after long-term intubation and ventilation care. The stenotic lesion was located at 2 cm below the vocal cords, and the length of the stenotic segment was about 2 cm. The anesthesia was induced and maintained with intravenous propofol and alfentanil. The airway was managed with LMA and distal tracheal intubation on the surgical field and we were able to maintain adequate ventilation and oxygenation throughout the operational period.

사각근간법에 의한 상완 신경총 차단후 발생한 횡격막 신경마비

강훈,임승운,윤미자 대한마취과학회 1995 Korean Journal of Anesthesiology Vol.29 No.5

Interscalene bracheal plexus block has became a popular method of anesthesia for surgical operation on the upper extremities. Possible complications are subarachnoid block, epidural block, phrenic nerve block, vagus or recurrent laryngeal nerve block, sympathetic nerve block, intravascular injection. But reported complications has been few and generally without prolonged effects. The following describes a patient who developed signs and symptoms suggestive of inadvertent phrenic nerve block and epidural anesthesia as complications of interscalene bracheal plexus block The complications were attributed to using of inferomedially directed 5 cm needle and then additional blind block of the brachial plexus with 5 or 6 times. We emphasize that if the appropriate length of needle and technique are not used, phrenic nerve paralysis and serious complications including total spinal or epidural block can occur as a result of a medially misdirected needle.

레이저 수술용 금속 기관내 튜브를 이용한 기관내 삽관후 발생한 기종격증과 피하기종

박종연,황재현,윤미자 대한마취과학회 1998 Korean Journal of Anesthesiology Vol.34 No.5

We report a case of pneumomediastinum, subcutaneous emphysema, and mild pneumothorax that occurred after endotracheal intubation with a metallic endotracheal tube for the laser operation. Fortunately, pneumomediastinum and subcutaneous emphysema were self-limited. But potentially life-threatening events such as upper airway obstruction, tension pneumothorax, pneumopericardium, mediastinitis might be possible. These complications may result from mucosal perforation of upper airway. The use of a tube with rigid and relatively narrower internal diameter than polyvinylchloride endotracheal tube, tough endotracheal intubation technique, high peak inspiratory pressure, suction technique and negative pressure are included as complication factors.

단일관튜브를 이용한 일측폐 마취시 발생한 좌측 폐출형 우측 폐로의 흡인과 저산소혈증

이정민,강봉진,윤미자 대한마취과학회 2000 Korean Journal of Anesthesiology Vol.38 No.2

The leading cause of death of massive hemoptysis is the aspiration of blood into the contralateral normal lung resulting in asphyxia. The management of massive hemoptysis can be performed by the evacuation of the blood, and the protection and ventilation of the uninvolved lung from aspiration. Double-lumen endotrachea1 tubes provide lung isolation, the ability to ventilate one or both lungs, and suction in case of acute endobronchial hemorrhage. We report a case of blood aspiration and hypoxemia which occurred during one long ventilation using single lumen endotracheal tube for left pneumonectomy. The patient was treated with a supplement of 100% oxygen, continual suctioning, and positive-pressure ventilation. If we had used a double-lumen endotrachal tube, it would have enabled us to separate both lungs, to clear the left lung, and to apply ventilatory support on the contralateral lung.
