본 연구는 아토피피부염을 가지고 있는 아동과 정상 아동의 식습관, 식품섭취양상 및 영양소섭취상태 비교를 위해 서울 소재 1개교와 울산의 2개 초등학교에 재학 중인 5, 6학년 388명을 대상으로 설문지를 이용하여 실시되었다. 조사는 2008년 7월 7일부터 7월 18일까지 총 2주간 실시하였으며, 조사대상자 중 아토피피부염군은 16.7%(65명), 정상 아동군은 83.3%(323명)로 나타났다. 아토피피부염 아동군은 남학생 29명, 여학생 36명으로 남아보다는 여아에게서 더 호발 되었으며 대부분 7-13세에 아토피피부염이 유발된 것으로 나타났다. 아토피피부염 아동군 중 병원치료를 받고 있는 경우는 20.0%였고 아토피피부염 유발에 영향을 주는 식품인 튀김, 패스트푸드, 우유 등의 섭취를 제한하고 있었다. 식습관의 경우, 아토피피부염 아동군이 정상 아동군에 비해 식습관이 불규칙적인 것으로 나타났으며(p<0.05), 아토피피부염의 유발과 연관 있는 식품 중 우유, 돼지고기, 게, 메밀, 닭고기, 고등어, 복숭아, 토마토의 섭취량이 정상 아동군에 비해 아토피피부염 아동군에서 높게 나타났다. 또한, 아토피피부염 아동군이 열량(p<0.001), 총 단백질(p<0.05), 식물성 단백질(p<0.001), 당질(p<0.001), 식이섬유소(p< 0.01), 칼륨(p<0.05), 아연(p<0.001), 비타민 B1(p<0.001), 나이아신(p<0.01), 비타민 C(p<0.05) 및 엽산(p<0.01) 등의 섭취량이 정상 아동군에 비해 유의적으로 적었다. 본 연구결과 아토피피부염 아동은 정상아동에 비해 식습관이 불규칙적이고, 아토피피부염 유발식품의 섭취량은 많았으며, 대부분의 영양소 섭취량이 정상아동에 비해 적었다. 이러한 결과는 식품과 연관성이 높은 소아 아토피피부염에 부정적인 영향을 줄 수 있을 것으로 보이며, 아토피피부염 아동에 대해 적절한 식품의 선택과 균형 잡힌 식생활 및 식습관 교정의 필요성이 매우 절실한 것으로 판단된다. 따라서 아토피피부염을 악화시키는 원인식품의 섭취를 제한하는 것과 더불어 올바른 영양교육 및 지도가 이루어져야할 것으로 생각된다.

연구배경 : Plasminogen activator inhibitor-l(PAI-1) 항원은 섬유소 용해에 관여하는 tissue type plasmingen activator(t-PA)를 억제하여 흉막액에 존재하는 섬유소가 용해되는 것을 억제하며 결국 흉막액의 응고를 촉진하게되며 패혈증 환자의 혈장에서 PAI-1 항원과 관계된 섬유소 용해능의 활성용 업종의 정도와 관계가 알려져 있슴으로 본 연구에서 흉막액내 염증 정도와 흉막액의 섬유소 용해 및 응고농 간의 상관관계를 알아보고자 하였다. 방 법 : 첫 흉막천자 후 얻어지는 검체와 검사 당일 환자의 혈액 3.8% citrate tube에 모은 후 즉시 2,000 rpm에서 30분간 원심 분리하였고 상층액을 분리하여 검사할 때까지 영하 $20^{\circ}C$에 보관하였다. 흉막액내 염증을 나타내는 지표로 흉막액의 포도당, LDH, pH, 총 단백질을, 염증세포의 침윤 정도를 나타내는 지표로 다형핵 백혈구, 림프구 및 총 백혈구를 측정하였고 혈액의 염증을 나타내는 지표로 호중구, 피브리노겐을 측정하였다. 흉막액의 섬유소 용해 및 응고능을 측정하기 위하여 D-dimer, PAI-1 항원, 트롬빈-항트롬빈 III 복합체를 측정하였으며 상관관계를 분석하였다. 결 과 : 대상환자는 30예 이었고 평균 연령은 51.4세 이었다. 흉막액의 원인 질환으로는 결핵성 흉막액 : 14예, 악성 흉막액 : 10예, 부폐렴성 흉막액 : 6예 이었다. D-dimer, PAI-1 항원, 트롬빈-항트롬빈 III 복합체는 흉막액에서 혈장치 보다 의의있게 높았으며 혈장치와 유의한 상관관계는 없었다. 혈장 PAI-1 항원과 트롬빈-항트롬빈 III 복합체는 원인질환 간에 차이를 보이지 않았다. 흉막액의 D-dimer와 트롬빈-항트롬빈 III 복합체는 원인에 따른 차이가 없었으나 흉막액 PAI-1 항원은 결핵성 흉막액에서 악성 및 부폐렴성 흉막액 보다 의의있게 높았다. 흉막액 염증의 경중에 따른 D-dimer(p=0.85), PAI-1 항원 (p=0.35) 및 트롬빈-항트롬빈 III 복합체(p=0.66)의 차이는 없었다. 흉막액 다형핵 백혈구, 림프구 및 총 백혈구수와 흉막액 트롬빈-항트롬빈 III 복합체는 부분적으로 유의한 상관관계를 보였다. 결 론 : 흉막 염증시 PAI-1 항원의 국소적 생성 가능성이 높았으며, 흉막액 염증 정도와 흉막액 D-dimer, PAI-1 항원 및 트롬빈 항트롬빈 III 복합체의 농도는 차이를 보이지 않았으며 흉막 염증시 흉막내로 유입된 염증 세포는 PAI-1 항원과는 무관하게 섬유소 용해 및 응고 과정에 관여한다고 생각된다. 흉막액 D-dimer와 흉막액 PAI-1 항원은 유의한 상관관계를 보이지 않아 이는 PAI-1 항원 이외의 다른 요인이 섬유소 용해 및 응고에 관여하고 있음을 암시하여주는 소견으로 생각된다.

Purpose: Lingual nerve (LN) damage may be caused by either tumor resection or injury such as wisdom tooth extraction, Although autologous nerve graft is sometimes used to repair the damaged nerve, it has the disadvantage of necessity of another operation for nerve harvesting. Moreover, the results of nerve grafting is not satisfactory. The nerve growth factor (NGF) is well-known to play a critical role in peripheral nerve regeneration and its local delivery to the injured nerve has been continuously tried to enhance nerve regeneration. However, its application has limitations like repeated administration due to short half life of 30 minutes and an in vivo delivery model must allow for direct and local delivery. The aim of this study was to construct a well-functioning $rhNGF-{\beta}$ adenovirus for the ultimate development of improved method to promote peripheral nerve regeneration with enhanced and extended secretion of hNGF from the injured nerve by injecting $rhNGF-{\beta}$ gene directly into crush-injured LN in rat model. Materials and Methods: $hNGF-{\beta}$ gene was prepared from fetal brain cDNA library and cloned into E1/E3 deleted adenoviral vector which contains green fluorescence protein (GFP) gene as a reporter. After large scale production and purification of $rhNGF-{\beta}$ adenovirus, transfection efficiency and its expression at various cells (primary cultured Schwann cells, HEK293 cells, Schwann cell lines, NIH3T3 and CRH cells) were evaluated by fluorescent microscopy, RT-PCR, ELISA, immunocytochemistry. Furthermore, the function of rhNGF-beta, which was secreted from various cells infected with $rhNGF-{\beta}$ adenovirus, was evaluated using neuritogenesis of PC-12 cells. For in vivo evaluation of efficacy of $rhNGF-{\beta}$ adenovirus, the LNs of 8-week old rats were exposed and crush-injured with a small hemostat for 10 seconds. After the injury, $rhNGF-{\beta}$ adenovirus($2{\mu}l,\;1.5{\times}10^{11}pfu$) or saline was administered into the crushed site in the experimental (n=24) and the control group (n=24), respectively. Sham operation of another group of rats (n=9) was performed without administration of either saline or adenovirus. The taste recovery and the change of fungiform papilla were studied at 1, 2, 3 and 4 weeks. Each of the 6 animals was tested with different solutions (0.1M NaCl, 0.1M sucrose, 0.01M QHCl, or 0.01M HCl) by two-bottle test paradigm and the number of papilla was counted using SEM picture of tongue dorsum. LN was explored at the same interval as taste study and evaluated electro-physiologically (peak voltage and nerve conduction velocity) and histomorphometrically (axon count, myelin thickness). Results: The recombinant adenovirus vector carrying $rhNGF-{\beta}$ was constructed and confirmed by restriction endonuclease analysis and DNA sequence analysis. GFP expression was observed in 90% of $rhNGF-{\beta}$ adenovirus infected cells compared with uninfected cells. Total mRNA isolated from $rhNGF-{\beta}$ adenovirus infected cells showed strong RT-PCR band, however uninfected or LacZ recombinant adenovirus infected cells did not. NGF quantification by ELISA showed a maximal release of $18865.4{\pm}310.9pg/ml$ NGF at the 4th day and stably continued till 14 days by $rhNGF-{\beta}$ adenovirus infected Schwann cells. PC-12 cells exposed to media with $rhNGF-{\beta}$ adenovirus infected Schwann cell revealed at the same level of neurite-extension as the commercial NGF did. $rhNGF-{\beta}$ adenovirus injected experimental groups in comparison to the control group exhibited different taste preference ratio. Salty, sweet and sour taste preference ratio were significantly different after 2 weeks from the beginning of the experiment, which were similar to the sham group, but not to the control group.

본 연구는 환경 문제점으로 대두되고 있는 슬러지의 효과적인 저감을 위한 방법으로서 효소를 이용하여 슬러지상 유기물의 가용화율을 높여서 소화조 내에서 미생물의 소화효율을 높이기 위한 것이다. 효소에 의한 슬러지의 가수분해 효율을 높이기 위하여 소량의 오존 (0.02 g $O_3$/g SS, 0.03 g $O_3$/g SS)으로 슬러지를 처리한 후 다양한 효소로 슬러지의 가수분해를 유도함으로써 슬러지의 SCOD를 높여 유기물의 가용화를 향상 시켰다. 여러 가지 효소 중 (Protease, $\alpha$-amylase, glucosidase, lipase)에서 protease가 가장 높은 슬러지의 가수분해 효율을 나타내었다. 오존과 효소로 전처리를 실시한 경우 오존 처리만 한 슬러지에 비해 SCOD 증가량이 높게 나타났으며, 단일 효소보다는 복합 효소를 사용했을 때 유기물의 가용화에 더 효과적임을 확인할 수 있었다. 또한, 효소 전처리시, 효소의 최적온도 조건 (50-6$0^{\circ}C$)을 맞추어 주었을 경우가 상온에서 효소 전처리를 실시했던 경우에 비해 SCOD값이 1.5-2배 정도 증가하여, 더 높은 가수분해 효율을 보였다. 반면, 소화반응에 있어서는, 효소 전처리를 실시한 슬러지와 효소 전처리를 실시하지 않고 오존전처리만을 실시한 슬러지의 소화반응을 비교해 본 결과, 효소전처리를 실시한 슬러지의 SCOD 및 TCOD의 감소량이 오존처리만 실시한 슬러지에 비해 높게 나타났으며, 단일효소보다도 복합효소에서 높은 SCOD와 TCOD의 감소량을 나타내었다. 따라서, 슬러지를 효소로 전처리하는 것은 슬러지 저감에 효과적으로 작용할 수 있을 것으로 기대되며, 이러한 슬러지의 효소 전처리 방법은 다양한 다른 슬러지 처리방법과 함께 슬러지 처리효율을 향상시키기 위한 방법으로 유용하게 이용될 수 있으리라 기대된다. 건전한 환경관리를 위한 유역관리기술 개발의 방향 등을 정리하도록 한다.O와 DABA에 반응하는 자외선 조사에 따른 $^1O_2$의 생성은 taurine의 영향을 받지 않았다.

도시기후와 같은 소기후를 연구하기 위하여는 도시는 물론 그 주변의 농촌지역에 이르기까지 조밀한 기상관측망이 필요하다. 그러나 한국에서 뿐만 아니라 선진제국에서도 기상관측망의 밀도가 도시기후를 파악하기에 충분할 만큼 조밀하지 못한 실정에 있다. 이러한 상항하에서 도시기후에 관하여 연구하려면 기초자료부터 측정하여야하는 어려움이 있으며, 따라서 그 연구의 필요성은 절감하면서도 실제적인 연구는 극히 부진하여 그 범위도 대단히 한정되어 있다. 1960년에 TIROS 1호가 미국에서 발사된 이래 다수의 기상위성이 궤도상에서 선회하며 많은 기상정보를 지상으로 보내주고 있다. 그리하여 현장관측이 어려운 각종 기상현상에 관한 정보를 짧은 시간안에, 그리고 경우에 따라서는 적은 비용으로 입수할 수 있게 됨으로써 기상연구에 박차가 가하여지게 되었다. 특히 최근에는 컴퓨터 프로그램의 발달과 더불어 해상력이 1km인 AVHRR의 영상을 대축척으로 확대하여 사용할 수 있게 되는 한편 여러가지 오류도 수정할 수 있게 되었다. 그리고 이들 위성으로부터 관측된 열적외선 영상은 도시열섬을 나타내는데 있어서 중용한 자료로 사용할 수 있게 되었다. 본 연구에서는 원격탐사 기법에 의한 도시열섬 연구의 가능성을 타진하여 보고자 NOAA AVHRR 영상을 이용하여 남한지역의 도시열섬의 존재와 수도권지역 열섬의 강도 및 형태를 알아보고 나아가 도시열섬과 여러 도시현상간의 관계를 밝혀 보고자 한다.

This study aims to provide the fundamental data for substantial nursing intervention in the elderly through a comparative appreciation on family support, self-esteem, and health status between the institutionalized elderly people and the home-staying ones. The subjects of this study are the institutionalized 108 elderly people of E and C Public Homes and the home-staying 109 elderly ones of O-Nho In Jeong(a kind of public recreational facilities for the aged) over the age of 65. The instruments for this research are based upon the tool(11 items, 5 points for each) for measuring family support developed by Choi, Young Hee(1984), a self-esteem scale done by Rosenberg (1965), the tools(20 items) for checking the health status of the elderly done by Lee, Young-Ja(1989). The sampling for this study has been carried on from July, 2000 until November, 2000. Questionnaire data were drawn up by personal interviews. The analyses of collected data are based on general characteristics calculated at the rate of 100 percentage to the average, t-test, ANOVA(some difference on a level with p<.05 being subsequently confirmed by DMR) for family support, self-esteem and health status, and Pearson Correlation to verify the hypothetical correlation among the subjects' family support, self-esteem and health status. The results of this study are as follows: 1. The difference between two groups in the light of family support, self-esteem and health status. (1) Family support - The rate of the family support that the institutionalized elderly people perceive turned out to be 22.13, that of the home-staying ones 30.99. (2) Self-esteem - The rate of the self-esteem that the former perceives proved to be 25.59, that of the latter 32.28. (3) Health Status - The rate of the health status that the former perceives turned out to be 39.67, that of the latter 51.60. 2. Family support, self-esteem, health status in terms of demographic characteristic (1) Family support - The group of institutionalized elderly people shows a tendency to be chiefly influenced by the death or life of the spouse and the number of the children; the group of the home staying ones to be chiefly influenced by the educational level (2) Self-esteem - The group of institutionalized elderly people shows a tendency to be chiefly influenced by educational level; the group of the home staying ones to be chiefly influenced by the amount of pocket money, the pocket money provider and the family main supporter. (3) Health Status - The group of institutionalized elderly people shows a tendency to be chiefly influenced by educational level; the group of the home staying ones to be chiefly influenced by age, the death or life of spouse, religion, and the educational level. 3. Correlation among family support, self-esteem, and health status The rate of correlation between family support and health status proved to be the highest (r=.549). After came the rate of correlation between health status and self-esteem, which turned out to be(r=.506). The last came the rate of correlation between family support and self-esteem, which proved to be(r=.406). According to this study, there is a conspicuously close correlation among family support, self-esteem, and health status for the elderly. Thus, it would be indispensable to seek out a variety of nursing intervention ways how the elderly could promote family support, self-esteem, and health status.

It is the purpose of this study to make clear the way in which people can lead a more desirable human life, that is, to ascertain the method of achieving therapeutic change through transaction between nurses and psychiatric patients. The various problems proposed by th9 above-stated aims of study can be shown, such as: What kind of influences does the method of a nurse′s communication have upon the response of psychiatric patients? 1) What are the general methods of communication used by the nurses? 2) Are there any differences between the control group and experimental group in the patients′ "Child" response? 3) Are there any differences between the control group and experimental group in the Patients "Adult" response? 4) What is the most desirable method of communication for therapeutic change in the patients? In an effort to solve the above questions this study attempted and managed to draw a random sampling of 200 patients being accommodated in the National Mental Hospital by dividing them into two groups, experimental groups and control groups, and recording the transactions between nurses and patients. In the course of carrying,: out this study, the experimental group was interviewed by the nurses specially trained In the P.A.C theory. and the control group interviewed at random by the nurses with no special training in communication. Further, the communication between nurses and patients in a free, relaxed atmosphere was allowed only for 15 minutes, whereupon the nurses were requested to make process-recording according to her memory of nurse patient transaction. The process-recording which recorded a series ol transactions between the nurses and the patients was analyzed according to Berne and Harris′transactional Analysis Standard. Through this standard, the writer of this study examined the significance of difference to compare the transactions brought forth between the experimental group and the control group. The following is a summary of the study which the writer of this thesis undertook. Hypothesis to The method of communication which the nurses usually apply to the patients will be higher in "Parent" than in "Adult". The communication which the nurses carried out in the control group turned out to be not significant between "Adult" and "Parent" Accordingly hypothesis 1. carne to be rejected. Hypothesis 2. The patients "Adult" response will be higher in the experimental group than in the control group. According to the result of a CR examination, as the communication showed a significant difference on P〈.01 level′ hypothesis 2 became affirmative. Hypothesis 3. The patients′"Child" response will be higher in the control group than in the experimental group. Hypothesis 3 proved affirmative since it showed an significant degree on P〈.01 level according to the result of a CR examination. Hypothesis 4 "Adult" response of the patient will be higher in frequency by nurses′"Adult" stimulus than nurse′s "Parent" stimulus Chi-square examination revealed significant difference on P〈.05 level. Hypo. 4 is affirmed. The following conclusions are drawn out based on the result of this study. 1) The generally used method of communication stimulus used by nurses for patients proved to be "Adult" and "Parent" in similar proportion. 2) The group in which the nurses could increase the patients "Adult" response proved to be higher in the experimental group than in the control group. Therefore, the communication (or stimulus) which has been applied in the experimental group can be said to be possible method of achieving therapeutic change. 3) Since the patients′"Child" response were higher in the control group than in the experimental group the communication method used In the control group was suggested as the less agreeable method of achieving therapeutic change than that used in the experimental Group. 4) "Adult" response of patient was elicited in significantly greater percentage when the "Adult" stimulus was used by the nurse. Therefore the most desirable method of-communication to give therapeutic change definitely was shown to be the "Adult" stimulus. Recommendations for further studies are as follows: 1) Studies on nurses′role perception in nurse-patient relationships. 2) Studies on patients′response to the method of communication used by nurses according to variables such as sex, social status, educational background, state of health. 3) Application of T.A, method to various groups of patients. 4) Study of various methods to improve student skill in use of process recording.

This research have been made to define how the IADL (Instrumental Activity of Daily Living) performance and the subjective health index of the Aged are affected by their residential circumstance, gender and age, and how deeply these two factors are related and interact. For the period of June 1 to July 31, 2000, we had conducted a questionnaire and direct interview with 693 persons over age sixty-five (65) in Daejon and in other adjacent area, grouping into three different residential types The Aged living at home, The Aged living at welfare facilities and The Aged living alone, and studied on how the IADL performance and the subjective health index of the Aged are influenced and interact as per their characteristics, daily activity and mentality. We had analyzed all the data obtained through this research by the method of : - analysis of frequency as per specific factors by SPSS 1O.0/PC+, - $x^2$ test, - t-test, - ANOVA, - multiple regression analysis by factors. The research concludes followings : a. It appears that the three (3) factors such as gender, age and residential circumstance of the Aged deeply affect the IADL performance and subjective health index of the Aged. (p<0.01) b. With regard to IADL performance of the Aged by the gender, it was analyzed that the female-Aged gains 23.8 point on average, which shows the performance of the female-Aged is less independent. (p<0.01). In addition, it was also found that the IADL performance is becoming less and less independent following their age increasing. In analyzing IADL performance by the residential type, it appears that the Aged living at welfare facilities gains the lowest 21.5 points and is least independent. It was also found that the Aged living at welfare facilities need some assistances from others for their performing IADL. (20-24 point) (p<0.001) c. With regard to the subjective health index of the all-Aged participated in this research, the analysis indicates 8.8 point and this is considered as a point of general standard (7-10 point). In analyzing this index by the gender, the female-Aged gains only 8.6 point which explains a lot of female-Aged consider they are not really healthy. (p<0.001) In analyzing this index by the residential type, the Aged living at welfare facilities and the Aged living alone gain the comparatively lower point, - respectively 8.4 point for the Aged living at welfare facilities and 8.8 point for the Aged living alone. The Aged living at these two residential types express they are obviously in a bad situation of health. (p<0.001) d. With regard to the factors affecting the IADL performance and the subjective health index of the Aged, it was analyzed that the IADL performance can largely be affected by the factors such as depression, frequency of going-out and age rising, and that the subject health index can also deeply be affected by depression, pain and by how much they are satisfied with their current living conditions. e. It was analyzed that the interacting between the IADL performance and the subjective health index is not that strong but even weak. As a result, we were able to conclude that the IADL performance is less independent in case of the female-Aged, the Aged living at welfare facilities, and following the age rising. As for the subjective health state the Aged themselves are aware of, we concluded that the female-Aged, the Aged living at welfare facilities and the Aged living alone, are more critical about their health. From this research, we were able to realize that, when the OMT (Orthopedic Manual Therapy) needed, the physical therapists are really required to have a correct and cautious understanding of the situation in which the aged persons are, and take care of them with more concerns and more improved treatment.

Objective: Our present studies were conducted to examine more effective isolating method of preantral follicles from mouse ovaries. Methods: ICR mice (3-6 weeks old) were sacrificed through cervical dislocation and their ovaries were removed and put into watch glasses containing Hams F-10 supplemented with 10% fetal bovine serum (FBS). Preantral follicles were isolated by three different methods; 1) enzymatical method and 2) mincing method, and 3) scraping method. Enzymatical method was carried out as following. Ovaries were bisected with a pair of fine 30G needles. Bisected ovaries were incubated at $37^{\circ}C$ and 5% $CO_2$ incubator in 2-well dish containing Hams F-10 supplemented with collagenase 600 lU/ml and DNAse 20 lU/ml. After 20 min., follicles were isolated by repeated pipetting. Isolated preantral follicles were collected, and the remnant of tissues was placed in incubator and previous procedure was repeated. Mincing method was carried out with a pair of fine 30G needles attached to 1 ml syringes and minced ovary. Scraping method was carried out with a pair of fine 30G needles and scratched to surface of ovary. The differences between isolating methods were analyzed using Student's t-test and Chi-square. Results were considered statistically significant when ${\rho}$ value was less than 0.05. Results: In handling time, mincing or scraping method ($28{\pm}3.42$ min or $16{\pm}1.58$ min) were significantly (p<0.00001) shorter than enzymatical method ($72{\pm}1.69$ min), and scraping method was significantly (p<0.01) shorter than mincing method. Total number of isolated follicles was significantly (p<0.0001) higher in enzymatical method ($49.8{\pm}3.91$) than in mincing or scraping method ($25.3{\pm}2.33$ or $20.5{\pm}1.75$). Isolated follicles in ${\leq}$90${\mu}m$ were significantly (p<0.005) higher in enzymatical method ($15{\pm}1.71$) than in mincing or scraping method ($7.8{\pm}0.98$ or $8.1{\pm}1.31$). In 91~130 ${\mu}m$, isolated follicles were significantly (p<0.0005) higher in enzymatical method ($33{\pm}3.27$) than in mincing or scraping method ($16.3{\pm}1.82$ or $10.7{\pm}1.38$). In ${\geq}$ 131 ${\mu}m$, isolated follicles were not significantly differences between all groups. In equal sizes, the rate of isolated follicles in ${\leq}$ 90 ${\mu}m$ was highest in scraping method (39.6% vs. enzymatical method: 30.1%, p<0.05; mincing method: 30.9%, p=0.11719, NS). Rate of follicles in $91{\sim}130$ ${\mu}m$ was significantly (p<0.05) lower in scraping method (52.7%) than in enzymatical or mincing method (66.3% or 64.5%). Rate of follicles in ${\geq}$131 ${\mu}m$ was highest in scraping method (8.3% vs. enzymatical or scraping method: 3.6%, p<0.05 or 4.6%, p=0.19053, NS). Conclusions: This study suggests that scraping method is simple and useful for isolation of preantral follicles, because this method reduced handling time and recovered enough follicles. The recovered rate of isolated follicles in diameter of 91 ~ 130 ${\mu}m$ was highest in all methods.
