The author reviewed the medical records of 96 typhoid fever patients who were diagnosed, admitted, and treated at Sea grave Memorial Hospital from January 1 , 1973 through August 31, 1975. Diagnosis was determined by clinical observation, aerology and bacteriology, eighty patients were treated medically, the remaining 16 patients required surgical intervention. The following results were obtained: 1) The age distribution of the patients revealed that 33.3% wert between 10 and 19 years old 21.9% were between 20 and 29, and 19.8% were between 30 and 39. The majority of patients were from these more active age groups. Male to female sex ratio was 1.3 : 1 2) Seasonal distribution was observed. Most illness occurred in the summer and autumn month 5. 3) 84. 3%of the patients came from farm families. 4) Duration between onset and admission averaged 16.0 days. The group without compilations was admitted after an average of 15. 1 days; The group with complications was ad-matted after an average of 19.4 days. 5) Methods of treatment before admission were as follows: 10.4% at medical clinics, 61, 5% at pharmacies (antibiotics 47.9%, other. drugs 13.5%), 7.3% by herb medications, 20.8% had no treatment. 6) Main clinical symptoms were as follows: fever 93.8%, headache 47.9%, abdominal pain 47.9%, chills 38.5%, cough 36.5%, general weakness 26.0%, nausea e vomiting 24.0% and generalized pain 21.9%. 7) Temperature of patients on admission: 22.9% were 39f or more, 67.6% were between 37℃ and 38℃, and 9.4% were 37℃ or less. 8) Occurrence of intensional bleeding after onset of disease averaged 9.3 days; perforation occurred at an average of 19. 1 days. 9) Interval between onset of major complication and surgical intervention averaged 2.8 days. 10) Among the 68 patients who underwent the bacteriological test the positive rate was 44.1% (30). The positive ,ales to, each separate culture method were as follows: 20.4% in the blood culture, 40.4% in the stool culture and 6.7% in the urine culture. Among these bacteriological positive patients 15 patients had a negative results or less than 160 titer of vidal reaction. 11) The initial vidal test of the total group showed a counts of 160 titer or more in 60.4% and less than 160 titer in 39.6%, 12) W. B. C. Counts in the uncomplicated group indicated that 32.5% were 6,000/㎣ or less, 47.5% were between 6,000 and 10,000, arid 20.0% were 10,000/㎣ or more. In the complicated group, 37.6% were 6,000/㎣ or less, 25,0% were 6,000-10,000/㎣ and 37.6% were 10,000/㎣ or more. 13) Duration of hospital stay of the patients averaged 6.4 days in the uncomplicated group and 12.7 days in the complicated group. 14) Subdiaphragmatic free air simple X-ray was found in 91.7% of the perforated cases. 15) Duration of antibiotic therapy until an febrile state was attained averaged 4.8 days in the uncomplicated group and 6.5 days in the complicated group. 16) Operative procedures were as follows: one layer simple closure of their perforation with or without debasement in 56.3%, drainage only in 6.3%, small bowel resection with primary anastomosis in 18.8% , externalization in 6.3%, cholecystectomy in 6.3%, The clinical findings of this study suggest the following recommendations. According to Top's report; 1% of typhoid fever patients treated with chlorarnphenicol and 2% of patients treated with other drugs become chronic carriers. Therefore, importance should be given to the strict control of these carriers. Immunization, improvement of sanitation and living standards are all needed for the prevention and treatment of disease, but a more serious problem is a lack of knowledge on the part of patients and their families. Thus it is most urgent to enlighten the citizens about the transmission and hygiene related to contagious disease. Legal restriction of sale of antibiotics at drug stores without a physician's prescription is an urgent matter for public health administrators. An even more important nursing responsibility is the reemphasis on health education both in the clinical setting and in the home.

Osteoporosis is the disease that is the most controversial issue with the aging tendency in 1990. It is an important issue in dealing with the health management for women in middle life. This study is designed to determine the relationships among the level of the knowledge of osteoporosis, the health promoting behaviors and the quality of life. The test has conducted a questionnaire survey of women with osteoporosis. This is a study that focused an interrelation of above issues and its purpose is to gain a foundation of a nursing intervention that can help to improve the qualify of life of an osteoporosis patients. The method of collecting data is collecting a questionnaire survey, individual interviews and records and the collected 123 questionnaire surveys are utilized for an data analysis. Questionnaire surveys are conducted in K and S Universities infirmaries and K general hospital in Seoul and C and J general hospital in near Seoul area from Sep. 27th to Nov. 4th, 2000. The instruments of this study were as follows: Yoon's used the revised and supplemented instrument to test the level of the knowledge of osteoporosis and she referred to the substance of Cassells & Knotz. Lee's revised and supplemented the instrument called Health Promoting Life style Profile that were invented by Walker, Sechrist & Pender and she used it to test the health promoting behaviors with the questionnaires added by this researcher. They are not related to the quality of life but relevant to the patients. Ro's tested the quality of life with the instrument that was invented by herself. The results of this study were as follows. 1. The general characteristics of this study subjects showed that the age of the patients was concentrated from 50 to 59. The periods after menopause was mainly from 6 to 10 years. Subjective symptoms that patients usually complain were musculoskelectal symptoms. 2. The results of measuring the level of the knowledge of osteoporosis, the health promoting behaviors and the quality of life were following. The level of the knowledge was the score 19.83 and it was above middle score out of the score 27 as full marks. In the result of the health promoting behaviors test, the score average was 2.58 with 4 point rating scale and it was about middle score. The quality of life test showed that average score was 2.92 with 5 point rating scale and it indicated that the quality was also around middle score. 3. The statistical test in the activities for promoting health according to the general characteristics of the patients showed that only monthly income has statistically significant difference(F-4.761, p=.004). The same test for the qualify of life indicated that the quality of life was higher from 1 to 5 years after menopause but it was not meaningful statistically. 4. In the correlation among the level of knowledge of osteoporosis, the health promoting behaviors and the qualify of life of the patients, showed a relationship between the health promoting behaviors and the qualify of life. The higher the health promoting behaviors, it was also higher the quality of life. But it was statistically significant with significant positive correlation.

The initial events required for periodontal regeneration is the attachment, spreading, and proliferation of appropriated cells at the healing sites. These have been reported that minocycline stimulates the attachment of periodontal ligament cells, and also $TGF-{\beta}1$ enhances the proliferation of periodontal ligament cells. The purpose of the present study was to evaluate the effects of $TGF-{\beta}1$ on the cellular activity of minocycline treated human periodontal ligament cells. Periodontal ligament cells were obtained from the explants of healthy periodontal ligaments of extracted 3rd molars or premolar teeth extracted from the patients for orthodontic treatment. The cells were cultured in minimal essential medium(${\alpha}-MEM$) supplemented with 10.000units/ml penicillin, $10,000{\mu}g/ml$ streptomycin and 10% FBS(fetal bovine serum) at $37^{\circ}C$ in a humidified atmosphere of 5% carbon dioxide and the 5th to the 8th passages of the cells were used. To evaluate the effect of minocycline on cell attachment, the cells were seeded at a cell density of $1.5{\times}10^4$ cells/well in 24-well culture plates and treated with $20{\mu}g/ml$ and $100{\mu}g/ml$ of minocycline for 1.5 h. After trypsinization, the cells were counted with hemocytometer and were taken photographs for observation of cellular morphology. To evaluate the effect of $TGF-{\beta}1$ on minocycline-pretreated periodontal ligament cells, the cells were seeded at a cell density of $1{\times}10^4$ cells/ well in 24-well culture plates and treated with $20{\mu}g/ml$ and $100{\mu}g/ml$ of minocycline for 1.5 h. After incubation, 1 and 10ng/ml of $rh-TGF-{\beta}1$ were also added to the each well and incubated for 1 and 2 days, respectively. Then, MTT assay, DNA synthesis($^3H-thymidine\;assay$), and protein and collagen assay(3H-proline assay) were carried out. In the MIT assay, after 200ul MTT solutionlconeentration of 5mg/ml) were added to the each well of the 24-well plates and incubated for 3 hours, and 200 ul DMSO were added so as to dissolve insoluble blue formazan crystals which was formed in incubated period. Then it read plates on a ELISA reader. For mitogenic assay, 1 uCi/ml $^3H-thymidine$ was added to each well for the final 2 hours of the incubation periods. After labeling, the wells were washed 3 times with ice cold PBS and 4 times with 5% TCA to remove unincorporated label and precipitate the cellular DNA. DNA, with the incorporated $^3H-thymidine$, was solubilized with 500 ul of 0.1% NaOH/0.1% SDS. A 250 ul aliquot was removed from each well and placed in a scintillation vial with 4ml of scintillation cocktail. Using an liguid scintillation counter, counts per minute(CPM) were determined for each samples. 3 uCi/ml $^3H-proline$ was added to each well for the final 4 hours of the incubation periods and total protein and percent collagen synthesis were carried out. The results indicate that minocycline treated group with $100{\mu}g/ml$ concentration for 1.5 hours significantly increased than that of control in cell attachment, and cell process is also evident compared with that of control in cell morphology, and the cellular activity and DNA synthesis rate of cells treated minocycline and $TGF-{\beta}1$ significantly increased than that of control values, but were below to values of the $TGF-{\beta}1$ only treated group in MIT assay and $^3H-thymidine\;assay$, and the total protein synthesis of minocycline and $TGF-{\beta}1$ treated group also significantly increased than that of control values, but the percent collagen synthesis of tested group significantly decreased to compared with control. On the above the findings, the tested group of minocycline and $TGF-{\beta}1$ did not increase the effect on the cell activity than $TGF-{\beta}1$ only tested group and the tested group of minocycline inhibited cell activity. This results indicate that minocycline was effective on cell attachment in early stage, but it is harmful to cell activity, that inhibitory effect of minocycline was compensated with stimulatory effect of $TGF-{\beta}1$.

The purposes of this study were to identify responses of nursing students following clinical maternity nursing practice, to develop data of further effective clinical maternity nursing practice, to understand nursing students perceive the natural maturation process toward pregnancy delivery and puerperal process, to help the nursing students achieve personality growth and development through clinical maternity nursing practice. The subjects were 35 senior nursing students from the Department of Nursing Science of Chung-Ang University. The data were collected from the 1st semester (Feb.22$\sim$June 9) to the 2nd semester(Aug.23$\sim$Nov.10), 1993 through self-reporting using an open ended questionnaire about perception and feelings regarding the normal delivery process. The data analysis used descriptive method. Results of the study were as follows : 1. Following clinical practice in maternity nursing, the responses of the nursing students were collected included both positive and negative aspects. The positive responses were classified in to four categories and each category included subgroups. One group, labelled as $\ulcorner$The birth of noble life$\lrcorner$ had a subgroup, (I felt the mystery and wonder of life), another group, $\ulcorner$After delivery, comfort and satisfaction$\lrcorner$ with the subgroup (I can bear to see the comfort and relief beyond pain) (C/S is better than vaginal delivery) (Very easy), the 3rd group, $\ulcorner$ I realized family friendship and support$\lrcorner$ with subgroup (Honorable, Magnificient) (I thank my parents ) (It's good to looking at my husband's support), and the 4th group, $\ulcorner$The birth of a healthy baby$\lrcorner$, with its subgroup, (baby looks pretty and healthy). 2. The negative responses were classified in eight categories and each category included subgroups. One group labelled as $\ulcorner$Fear$\lrcorner$, had subgroups of (Terrible, Horrible) (Shock) (Dread), another group, $\ulcorner$Tension$\lrcorner$, and its subgroup, (I became tense about stories heard before clinical practice), the 3rd group, $\ulcorner$surprise$\lrcorner$ and its subgroup (I was surprised at the delivery process), the 4th group, $\ulcorner$Power lessness$\lrcorner$ and its subgroup, (I watched the labor pain impatiently), the 5th group $\ulcorner$Apathy$\lrcorner$ ; and its subgroup, (I didn't feel the empathy for the labor pain of the pregnant women), the 6th group, $\ulcorner$Disgust$\lrcorner$ and its subgroup, (Disgust, Embarrassed), the 7th group, $\ulcorner$Inevitable destiny$\lrcorner$ and its subgroups (necessity of self-sacrifice and difficulty) (I accepted it as a women's destiny) (I can't do it), the last group, $\ulcorner$There seems to be trouble$\lrcorner$ and its subgroup, (It seems to have been a little too hard for mother and baby). Suggestions for further studies are as follows : 1. Nursing students should receive intensive education about $\ulcorner$The birth of noble life$\lrcorner$ $\ulcorner$After delivery, comfort and satisfaction$\lrcorner$ $\ulcorner$I realized family friendship and support$\lrcorner$ $\ulcorner$The birth of a healthy baby$\lrcorner$, so that a more positive attitude can be developed before clinical maternity nursing. 2. Nursing students should be given an orientation which is reality based and related clinical maternity nursing (using for A.V. Materials), so that they will not feel they tension, of the negative categories. 3. Nursing students should be received articles on Pain Relief Method, so that they will be prepared activie and positive in the clinical practice, and therefore they will not feel the powerlessness, of the negative categories. 4. F/U for responses of nursing students should be checked following clinical maternity nursing to evaluate the effects of the instruction.

This is a study which attempt to analyze changing patierns of economic active popu-lation, t o estimato- future patterns, and exa- mine vartons problems arises by changing c ire u mst ances of t he labor force market in- clunging soici al, economic ic, heathl th and demoi-graph ic aspects. We have constructed series of wotking life table which are useful in syt uiolyioig the lirocess of growth and structural change of labor force. Work i ng life tables represent ihie life eyele of econrmic' activity in hi ypothetical cohorts, that is. gen-erat i on of men Sn bject at eat' b period ot f their lives th given ra to's o mor tali it y and of par-- tici pation in economic activities. The tabloes prot' ide measorues of the alvet'age he ng t able of economically aeti \- e life. and agespecific rates of en trannee' into and retirement from the hahn' force. In const routing working life tables, age-specific activity rates and life tabole popula- titoto which represents contemporary condi-tions of moortality in Korea au'e the basic' maltoerials. We have derived the age-specific rates foorm economically active population survey, whoich were conducted by the Bureau of Statistics, Economic Planning Borard of the Korean government. Working life tables are constructed for men wtable these materi- als in the year of 1970, 1980 and 1988 by a modified Wolfbein-Wool's method. Some of the findings may be summerized as follow : 1) A central part of constructing working life table is calculation of stationary' economic active population, which represents the number of men in the stationtary population extoected to be in the labor force at each age group in the life span. The stationary economic active population by age have generally a universal pattern, where they rise sharply in the early twenties, approach its' peak in the thirties decline thereafter. at first graolually and then more rapidly at an advanced age. Korean men show the same general pa ttern of age distribution of stationary eco-- nomic active population with sharp increase hegining from the age interval of 20 to 24, reaching to maximum level at older age. The population. however, presumably, increased substantially due to increaseing school atte endance rates. Another difference exiSts in the youngest age groups, that is the activity rate in the year of 1988 is lower than that of Japan. The table shows an analysis of changes in the age distrihution of labor force between 1970, 1980 and 1988. 2) It was shown an analysis of changes in the age distribution and cause of separation from labor force. The entrance rate to labor force has increased from 18~\5 persons to 299 persons per 1000 head of stationary population between that of 1980 than that of 1988 for Korean men in 20~24 age group. The entrace rate to labor force shows a rapid entrance appearance concentrated on the 15~24 age group. The separation rate from labor force by retirment in Korea in the year of 1988 shows a great difference of the about four times as much as that of Japan. 3) The functions of table illustrate the patterns of working life of males in Korea in 1970, 1980 and 1988. The average remaining number of economically active years, e at age 15 in 1988 is 46.39 which is 2.12 years of increase compared with that of at age 15 in 1970,1980 and 1988 are 43.90,44.27 and 46.39 respectively, showing steadily increase dur- ing the past double decade the increase in the length of economically active life various age may be considered to have come both from extention of general life expectancy and from increasing entrance rate to economic activity in high age that of working is far greater in 1988 than that of 1980. The gaps between expectation of life and average remaining years of economically active widened due to rapid improvement of mortality level in Ko- rea. This observation together with the population pressure by the appearance of a group of younger population implies that constant increase of economically inactive population among older age group.

기존의 용융탄산염 연료전지용 연료극인 Ni-Cr전극은 제조과정이 복잡하며, 운전조건에서 전극의 소결과 creep현상으로 인하여 전극의 기공률과 두께가 감소하는 문제점이 있어 상용화에 걸림돌이 되고 있다. 이에 본 연구에서는 Ni-Cr계 전극보다 creep저항성이 우수하다고 알려져 있는 Ni-Al계 합금을 사용하였다. 또한 공정의 단순화로 비용을 절감시키기 위해, 소성과정을 제외하고 tape casting과 건조과정을 거친 green sheet를 단위전지에 장착하여 전처리 과정 중에 소결시키는 in-situ 소결법에 대해 연구하였다. 그러나 기존의 전처리 방법을 이용한 단위전지 평가에서 Ni-Al 합금의 상분리 현상으로 인해 기대하였던 creep저항성 향상을 확인하지 못했고, 운전중 Ni-Al합금 연료극에 단위전지의 구성요소인 matrix 기공크기보다 작은 기공(${\leq}0.4{\mu}m$)이 다량 생성되어 전해질 재분배를 일으켜 성능이 하락하는 문제점이 나타났다. 따라서 이러한 문제점을 해결하고자 전처리 조건을 변화시키며 실험을 수행하였다. 그 결과, 비활성 기체인 질소를 일정한 구간에 사용함으로써 기존 전처리에서 발생하였던 Ni-Al 합금의 상분리 현상을 억제할 수 있었으며 이로 인해 creep저항성 또한 향상시킬 수 있었다. 그러나 운전 중 생성되는 matrix기공크기보다 작은 기공(${\leq}0.4{\mu}m$) 형성비율은 억제할 수 없었다. 위의 전처리 조건을 가지고 단위전지 운전실험을 하였고, 전해질 함침비율을 조절함에 따라 성능을 향상시킬 수 있었으며 2000시간 동안 일정하게 유지함을 확인하였다. 이로부터 기존의 소성전극과 비교하여 많은 장점을 가지고 있는 in-situ 소결법의 가능성을 확인할 수 있었다.

목적: 혈관내피성장인자(VEGF)와 그 수용체는 종양의 성장과 전이에 매우 중요한 역할을 한다 3개의 수용체가 알려져 있는데 그 중에서도 VEGFR2 (Flk-1/KDR)가 종양 angiogenesis에 매우 밀접하게 관련한 것으로 알려져 있다. 본 연구에서는 마우스 Flk-1 항체로 알려진 DC101에 I-131을 표지하여 매우 공격적인 종양으로 알려진 흑색 종의 치료 정도를 확인해 보고자 하였다. 방법: 하이브리도마 세포에서 Flk-1 항체인 DC101을 분리하여 western blot, ELISA, maldi-tof 방법을 이용하여 순도를 확인하고 항체 에 chloramin T를 이용하여 I-131을 표지하였다. 누드마우스에 B16F10세포를 주사하여 흑색종 모델을 만들고 평균 $200-250\;mm^3$으로 키워 $^{131}I$-DC101을 주사하여 영상과 시간별 장기섭취율(%ID/g)을 비교하고, 종양내 Flk-1 발현을 확인하기 위하여 면역염색 등을 시행하였다. 흑색종 동물모델을 5개 군으로 나누어 각각 치료를 시행하였다. 1군은 PBS만을, 2군은 $^{131}I$-DC101 $50\;{\mu}g(200\;{\mu}Ci)$을, 3군은 DC101 $50\;{\mu}g$을, 4군은 $^{131}I$-DC101 $30\;{\mu}g(200\;{\mu}Ci)$을, 5군은 $^{131}I$-DC101 $15\;{\mu}g(200\;{\mu}Ci)$을 각각 매 3일 ${\sim}$ 4일마다 주사하고 전체 5회를 주사하였고 종양볼륨을 측정하였다. 결과: $^{131}I$-DC101을 흑색종 모델에 정맥주사하고 78시간까지 영상을 얻은 결과 시간에 따라 종양섭취가 증가 하는 영상을 보였다. 시간대별 장기섭취를 정확히 확인하기 위하여 1시간, 6시간, 24시간, 48시간, 72시간 장기섭취율을 비교한 결과 시간에 따라 혈액내 방사능치가 서서히 감소하였고 다른 장기의 섭취도 시간에 따라 감소하였고 종양의 섭취는 48시간까지 증가하였다가 그 이후는 감소하였다. 흑색종 동물모델에 $^{131}I$-DC101 치료를 시행한 결과 3번째 주사까지는 각군간의 유의한 차이를 보이지 않다가 4번째 주사를 시행한 때부터 1군과 2군, 또는 1군과 4군간의 유의한 차이를 보이기 시작했다. 또한 5번째 주사 이후에는 5군에서도 유의한 차이를 보여 I-131 에 의한 효과가 뚜렷해짐을 확인하였다. 결론 마우스 Flk-1 항체로 알려진 DC101을 흑색종 모델에 정맥내 주사하였을 때, 종양성장억제 효과를 보이지 않는 항체양에서도 I-131을 표지하여 치료를 시행했을 경우에는 효율적인 종양성장억제 효과를 보였다.

본 실험은 육계에서 생균제 Streptococcus faecium C-68(SF)과 항생제 colistin (Col)의 단독 또는 혼합 급여가 증체율과 장내 세균총 변화에 미치는 영향을 조사하기 위하여 실시하였다. 암수 동수의 초생추 252수를 공시하여 Col과 SF를 첨가하지 않은 기초사료구(대조구), 기초사료＋Col 10ppm첨가구, SF 0.04%구, SF 0.04%＋col 10ppm구, SF 0.08%구, SF 0.08%＋col 10ppm구 등 6개 처리구를 두었다. SF 0.04%구와 SF 0.08%구의 Streptococcus faecium 생균수는 사료 g당 각각 7$\times$10난, 1.4$\times$10개가 되도록 하였고, 사료는 옥수수와 대두학을 주원료로 하여 7주간 급여하였다. 사양실험이 진행되는 동안 처리구별로 분내 세균총의 변화를 알아보기 위하여 매주 말 신선한 분을 사료로 무균적으로 채취하여 조사하였고, 장내 세균총의 변화를 조사하기 위해 4주와 7주말에 처리당 9수씩 희생시켜 대장부분의 내용물을 채취하여 세균총의 분포를 조사하였다. 각 처리구 실험사료의 영양소 이용률을 조사하기 위하여 3주와 6주말 전분 채취법에 의하여 대사실험을 실시하였고, 7주말 각 처리구 별로 9수씩 희생시켜 소장의 길이와 무게를 측정하였다. 평균 증체량은 SF 0.08%(2.37kg)와 SF 0.08%＋col (2.34kg)을 첨가한 처리구가 대조구(2.18kg)보다 유의적으로 높았으나 (P＜0.05), 다른 처리구의 증체량은 대조구에 비하여 통계적인 차이가 없었다. 사료요구율은 SF 0.04%구를 제외한 모든 첨가구들이 대조구보다 더 개선되었고(P＜0.05), 건물, 조단백질, 조지방, 총 탄수화물 등과 같은 영양소의 소화율은 전 기간 내내 SF나 Col의 첨가에 의한 변화를 볼 수 없었다. 예상했던 대로 SF첨가구의 분 중 Streptococci는 유의성 있게 증가되었는데 SF 0.04%구와 SF 0.08%구, SF 0.08%＋col구에서는 통계적인 유의성이 인정되었다(P＜0.05). 그러나 colistin의 단독첨가에 의한 Streptococci의 변화는 볼 수 없었고 Col과 SF와의 혼합 첨가구에서도 Col첨가가 Streptococci수의 변화에 미치는 영향은 볼 수 없었다. 분 중의 coliforms수는 SF와 Col의 첨가된 사료의 급여에 의해 현저히 감소되었다(P＜0.05) 그러나 SF와 Col의 혼용효과는 관찰할 수 없었다. 장내 세균총의 분포 변화도 분중의 세인총 변화와 같은 양식을 나타냈다. 소장의 길이는 SF 0.08%구와 SF 0.08%＋col 10ppm구에서 SF를 급여하지 않은 처리구보다 10%정도 유의하게 긴 것으로 나타났다(P＜0.05). 그러나 소장의 무게(empty weight)는 대조구에 비하여 SF 0.08%구와 SF 0.08%＋col구에서 가벼워졌고, Col과 SF를 단독 또는 혼용 급여한 모든 처리구의 단위길이 당 소장무게는 유의성 있게 감소된 것을 볼 수 있었다(P＜0.05). 전체적인 결과를 볼 때 SF가 0.08%첨가된 구에서 육계의 증체량 개선효과가 가장 좋은 것으로 나타났다. 10ppm의 colistin첨가는 SF와 혼용했을 때나 10ppm 그 자체만으로는 육계의 증체효과 또는 양내 세란총 변화의 관점에서 볼 때 유익하지 못했고, SF와 Col은 소장의 벽 두께를 않게 변화시키는 효능이 있다고 추측된다.
