Effects of Chitosan Intake on Bone Mass, Bone Related Metabolic Markers in Ovariectomized Rats

Jang, Ye Sun,Lee, Myoung Hee 제주관광대학 2005 論文集 Vol.11 No.-

In the present study we examined both the etiology of bone loss induced by dietary chitosan and the preventive effect of vitamin C supplementation. Rats were OVX and maintained on one of the following diets for 4 weeks: 10% cellulose (CE), 10% chitosan (CH) and 10% chitosan with sodium ascorbate (CHVC). Vitamin C supplementation to CH caused an increase in Ca and P contents of femurs as well as BMD of L4, with a decrease in urinary Ca excretion. There was no significant difference in intestinal Ca absorption between CH and CE, whereas CH intake significantly reduced intestinal P absorption. CH caused a significant reduction in BMD and stiffness of femurs as well as fourth lumbar vertebrae (L4). The bone loss in CH rats was accompanied with an increase in urinary Ca excretion and a decrease in serum Ca as well as a significant increment in serum PTH and 1,25(OH)2D3. These results indicates that dietary chitosan with low Ca intake possibly induces the loss of bone mass by enhacing urinary Ca excretion, rather than by inhibiting Ca absorption, and that vitamin C supplementation could prevent bone loss caused by chitosan through the increment of retained Ca followed by suppression of urinary Ca excretion.

This study was designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

The quantitative dentin-removing ability of ultrasonic synergistic system was studied to compare with conventional techniques such as hand instrumentation and Giromatic preparation. Standardized seventy-two extracted, single-rooted human teeth were divided into six groups of equal numbers. The instrmentation with number 40 for each group was done for 1 minute, as follows; Group 1:root canals were instrumented by the hand, H-file, push-pull stroke. Group 2:root canals were instrumented by the automated Giromatic, H-file, a quarter-turn push-pull motion. Group 3:root acanals were instrumented by the ultrasonics, H-file,push-pull action. Group 4:root canals were instrumented by the hand, K-reamer, push-pull stroke. Group 5:root canals were instrumented by the automated Giromatic, K-reamer, a quarter-turn push-pull motion. Group 6:root canals were instrumented by the ultrasonics, K-reamer, push-pull action. The mean weight loss on each group was statistically compared with each other by use of Student's t-test. The results were as follows: Ultrasonic techniques were significantly superior to conventional techniques, especially using of H-file. There was no statistically significant difference in ability of the hand and Giromatic techniques to remove intracanal dentin. The qroups used H-file instrumentation were more efficient than those of K-reamer in general.

Economic activities of korean women is in the trend of continuous increase. The ratio of Korean women entrepreneurs is 36 percents of total business men and women, and has already reached the level of advanced countries. As a result of the basic statistic research on total business entities in korea, Korean women entrepreneurs are in the trend of annual increase, such increase performs the promotion of women economic activities, which ,in turn, develops women socio-economic position, dissolves the differentiation of females from males, and causes the effects on enlargement of employment, and, in the long, contributes the development of national economy. However, in comparison with the increase in the number of women entrepreneurs, the size of business enterprises is vary small to the extents as for the ones which have less than five employers to reach the degree of 92 percents of total women enterprises. in addition, in contrast that the economic contribution of women is uprising than ever before, the support of central or local government and financial agencies is relatively short. although 'the act on supporting women-owned business' is established and performs supporting policies, by the lack of recognition of the women business systems, in contrast of the increase of the number, owing to the skewness of small size and unwealthy and lower growing business, the real growth of them is getting declined. The study is based on the Research of Women Business issued bi-annually since 2001 by Small and Medium Business Administration, and Korean Women Entrepreneurs Association, and on the statistics of the basic research on national business enterprises in 2006. The purpose of the study is on the situation analysis and on the recognition of the realities of creation and business operation of women business enterprises, and on what the factors affected on the decline of them are. and on supporting policies about how the growth of women business enterprises can be developed. Especially, the study centers on the women business enterprises located in Kwangju-Jeonnam-Jeonbuk district, which reach only 14.7 percents, in comparison with 36 percents of the numbers of total business enterprises.

The plasma generally, ionized gas state, is the 4th state composed the universe. Generating the plasma artificially has been studied by spending energy and it has a lot of applications in human's life. There are several merits to modify the surface of polymer using plasma. Above all, plasma maintains the property of polymer because of it changes the property of surface only. Also, it doesn't use any organic solvents and it is the environment friendly process because of there are no waste under processing. Furthemore, in case of high-pressure plasma, it is possible that automated-processing continuously. In this study, we tried the reforming of surface to rise the adhesive strength between the material of polymer, experimented the rising of adhesive strength through a experiment of peel strenght by virtue of processing time and using gas, confirmed the change of polymer's surface through measuring the surface contact angle analyzer and scanning electron microscopy(SEM).
