The study is to reveal what the married women has experienced while they were on the contraception. Data were gathered for four mothers beginning on October, 1996. Interviewees were 22 women. Data were analyzed by Colaizz's phenomenological data analysis method. Three basic structures of contraception experience were derived. Those are 'Conflict in choosing contraceptive methods', 'Dilemmar in sexual relationship', and 'Responsibility concerning contraception'. Contraception was a major task of the married women, and they difficulties, because sexual relation was usually initiated by husband and contraception by husband was negatively perceived in Korea culture. Conflict were caused by inavailability of information, side effects of contraceptive methods, and limitation of the contraceptive methods. Interviewees perceived that responsibility of contraception was on them, but they expressed feeling of anger against they burden by contraception. Most interviewees took initiation of contraception to keep their body healthy. Some of the interviewees got husband's cooperation through negotiation and shared responsibility with husband. Suggestions were as follows ; (1) Sex education, especially on communication about sex, is necessary to the married women. (2) Informations on contraception should be provided in the private environment. (3) Studies on husband's contraception experience are required to promote husband's cooperation.

A maternity ward in a hospital in Seoul has an educational program for postpartal mothers since its opening, but evaluation on the program has not been done. This study was to find whether the educational program contributed to increase of knowledge and confidence of the post-partal mothers in the area of postpartal self-care and the newborn baby care or not. This study aimed at improvement of the educational program for posrpartal mothers and the newborn babies. Subjects were 40 primiparae who were admitted to the obstetric ward in a general hospitals in Seoul from August 20th to September 10th, 1995. Subjects were those who had no labor pain at the admission time, had no complications during labor and delivery, gave a birth to a healthy baby, and agreed to participate in this study. All subjects were well educated and were in well-to-do group. Most of them received antenatal care adequately. They were tested on knowledge and self-confidence in the area of postpartal self-care and infant care two times, one at the admission time and the other prior to discharge. After the first test, nurses in a maternity ward and nursery taught them on postpartal self-care and infant care. Education consisted of a 1 hour planned program and incident teachings done at bed side. Four tools were developed by authors based literature review. The test tool for knowledge of postpartal self-care consisted of 15 items which included the definition of postpartum, dangerous symptoms in postpartum, lochia, time to begin coitus, postpartum exercise, sitz-bath, and perineal care. The test tool for self-confidence in postpartal self-care included such items as emergency care on dangerous symptoms in postpartum, sexual life and contraception after postpartum, self-confidence in postpartum exercise and perineal care. The test tool for knowledge of newborn baby care consisted of 18 items which included bathing, umbilical cord care, vaccination, breast feeding, abnormal symptoms of neonate. The test tool for self confidence in the newborn baby care included umbilical cord care, vaccination, breast feeding, emergency care for baby. Analysis of demographic data were analyzed with calculation of percentage. Score differences between the first test and the second test were analyzed with paired t-test. SAS / PC (Release 6.04 for DOS) program are as follows. 1. Mothers' knowledge of postpartal self-care increased significantly after education (t=10.04, df=38, p=0.0001). 2. Mothers' self-confidence in postpartal self-care increased significantly after education (t=6.53, df=38, p=0.0001). 3. Mother's knowledge of the newborn abay care increased significantly after education (t=9.74, df=38, p=0.0001). 4. Mothers' self-confidence in the newborn baby care increased significantly after education(t=8.22, df=38, p=0.0001) Suggestions for further studies and nursing practice were as follows. 1. We suggest studies by randomized control-group pretest-posttest design or nonequivalent control group pretest-posttest design will be done. 2. We suggest follow-up studies to find if mothers's confidence will last or not after discharge. 3. We suggest general hospitals to establish a phone-counseling system.

본 연구에서는 노루궁뎅이 버섯균사체를 비타민나무 잎에 배양하여 조제한 노루궁뎅이 버섯균사체-비타민나무 발효물 열수 추출물이 생체고분자의 산화적 손상과 세포사멸을 보호할 수 있는지를 관찰하였다. 노루궁뎅이 버섯균사체-비타민나무 발효물의 항산화 활성을 DPPH radical, ABTS radical, peroxyl radical 소거활성 측정을 통해 알아보았다. 그 결과 노루궁뎅이 버섯균사체-비타민나무 발효물을 처리한 DPPH radical 소거활성은 500 μg/mL 농도에서 65.06%, ABTS radical 소거활성은 50 μg/mL 농도에서 98.83%, peroxyl radical 소거활성은 100 μg/mL 농도에서 44.03%로 높은 항산화 활성을 나타내었다. 노루궁뎅이 버섯균사체-비타민나무 발효물은 DNA의 산화적 손상을 효과적으로 억제하였다. 노루궁뎅이 버섯균사체-비타민나무 발효물 역시 사람의 혈청단백질과 Cu,Zn-SOD의 산화적 손상을 억제하였다. 세포에 H₂O₂를 처리하였을 때 세포생존율에 비하여 발효물을 100 μg/mL 농도로 전 처리한 세포생존율은 21.59% 높게 증가되었다. 또한 발효물을 50 μg/mL 농도로 처리했을 경우 세포 내 ROS의 축적이 유의적으로 감소되었다. 따라서 노루궁뎅이 버섯균사체-비타민나무 발효물은 항산화 활성뿐만 아니라 산화적 스트레스에 의해 야기되는 세포 독성에 대한 보호 작용이 뛰어난 것으로 사료된다. In this study, hot water extract from sea buckthorn (Hippophae rhamnoides L.) leaves fermented with Hericium erinaceum mycelium (SBT-HE) was assessed for protection against oxidative modification of biological macromolecules and cell death. Antioxidant activity of SBT-HE was evaluated based on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, 2,2"-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical, and peroxyl radical scavenging assays. SBT-HE showed 65.06% DPPH radical scavenging activity at 500 μg/mL, 98.83% ABTS radical scavenging activity at 50 μg/mL, and 44.03% peroxyl radical scavenging activity at 100 μg/mL. SBT-HE significantly inhibited DNA strand breakage induced by peroxyl radical. SBT-HE also prevented peroxyl radical-mediated human serum albumin modification. SBT-HE effectively inhibited H2O2-induced cell death and significantly increased cell survival by 21.59% at 100 μg/mL. SBT-HE also reduced intracellular reactive oxygen species levels in H₂O₂-treated cells. The results suggest that SBT-HE can contribute to antioxidant activity and protect cells from oxidative stress-induced cell injury.

The hot water extract from Artemisia capillaris fermented with Hericium erinaceum mycelium (AC-HE) were assessed for the protection against oxidative modification of biological macromolecules and cell death. Antioxidant activity of AC-HE evaluated using 2,2-diphenyl-1-picrylhydrazyl radical, 2,2 -azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical and peroxyl radical scavenging assays. AC-HE showed 61.73% DPPH radical scavenging activity at 500μg/mL, 97.39% ABTS radical scavenging activity at 250 μg/mL, and 44.18% peroxyl radical scavenging activity at 100 μg/mL. AC-HE were shown to significantly inhibited DNA strand breakage induced by peroxyl radical. AC-HE also prevented peroxyl radical-mediated human serum albumin modification. AC-HE effectively inhibited H2O2 induced cell death and significantly increased of the 11.47% cell survival at 100 μg/mL. AC-HE also decreased intracellular reactive oxygen species (ROS) levels in H2O2-treated cells. The results suggested that AC-HE can contribute to antioxidant and protected cells from oxidative stress-induced cell injury. 노루궁뎅이 버섯균사체(Hericium erinaceum)를 인진쑥(Artemisia capillaris)에 배양하여 조제한 AC-HE 열수 추출물이 생체고분자의 산화적 손상과 세포사멸을 보호할 수 있는 지를 관찰하였다.
