The present study evaluated the possibility of dumbbell exercise as to improve the physical fitness and the health starus of old people in rural area. Although eighty seven volunteers of old women (over 64) living in Seonsan, Gumi city were subjected, twenty of them were attended the whole program for 6 months and the data from the twenty was analysed in this study. The results were drawn out from comparison of the body constitutuion, the physical strength, the medical aspectrs, and the questionaires of before and after this program. They showed increased physical fithess tested by grip strength (left), bar gripping reaction time, standing trunk flexibility, on foot standing test through dumbbell exercise for 6 months. Questionaire revealed the betterment of dietary pattem during this program. In the light of in these results, it is possible to conclude that dumbbell exercise had improved the basic physical condition and the health status through the increasement of physical fitness and dietary pattem change. Therefore, dumbbell exercise would be a useful program for the old people in reual area to improved their health status.

감잎의 Phenolic Compounds가 에탄올을 투여한 흰쥐의 항산화계 및 기타 효소활성에 미치는 영향

감잎 phenolic compoumds가 흰쥐에서 에탄올투여로 생성된 oxyger free radical대사와 각종 효소활성에 미치는 영향을 검토하기 위하여 실험동물을 정상군, 감잎 phenolic compounds 투여군(70 mg/kg), 에탄올 단독투여군, 에탄올과 감잎 phenolic compounds 소량 병합투여군(70 mg/kg), 에탄올과 감잎 phenolic compounds 대량 병합투여군(140 mg/kg)의 5군으로 나누어 6주간 사육하여 체중증가율, 식이요율 및 혈청중 ALT, ALP 및 LDH활성 측정과 간손상 억제효과를 검토하기 위하여 간조직중 유리기 생성계 효소인 XO활성, 유리기 해독계 효소인 SOD, calaase 및 GSH-Px활성과 지질과산화물인 TBARS 및 GSH함량을 측정한 결과는 다음과 같다. 각 분획의 항산화력은 EtOAC분획의 항산화력이 가장 우수하였다. 에탄올만을 투여한 군은 정상군에 비하여 체중증가율과 식이효율이 유의적으로 감소되었고 감잎 phenolic compounds를 병합투여한 군은 체중증가율과 식이효율이 정상군에 근접하게 상승되었다. 간 손상의 지표로 알려진 ALT, ALP 및 LDH활성은 에탄올투여로 정상군에 비하여 유의하게 증가되었으나 감잎 phenolic compounds를 투여하여 ETH에 비하여 많은 감소를 보였다. 간조직중 유리기 생성계 효소인 XO활성은 에탄올 투여로 정상군에 비하여 큰 폭의증가를 보였으나 본 실험기간내에서는 유의성있는 변화는 아니었으며 감잎 phenolic compounds를 투여하여 에탄올 투여로 증가된 효소활성이 ETH에 비하여 감소는 되었으나 유의한 변화는 아니었다. 유리기 해독계 효소인 SOD, catalase 및 GSH-Px활성은 에탄올투여로 정상군에 비하여 크게 증가되었으나 감잎 phenolic compounds 투여로 ETH에 비하여 뚜렷한 저하효과를 나타냈다. TBA반응성생산물량에서 에탄올투여로 과산화지질함량이 CON에 비하여 많이 증가되어 유의한 변화를 나타냈으나 감잎phenolic compounds는 에탄올 투여로 증가된 함량을 ETH에 비하여 ⅓∼½정도 용량의존적으로 감소시켰으며 PEI의 경우 그 함량이 CON보다 오히려 낮았다. 또한 에탄올투여로 감소된 간조직중 GSH함량은 감잎phenolic compounds투여로 정상군보다 증가되었다. 이상의 실험결과에서 감잎phenolic compounds가 에탄올투여로 증가된 유리기 해독계 효소인 GSH-Px활성을 큰 폭으로 감소시키고 에탄올투여로 감소된 비효소적 항산화작용을 나타내는 GSH함량을 다량 증가시킴으로서 지질과산화물에 대한 방어력이 증강되어 나타난 결과로 여겨지며, 또한 혈청중의 ALT, ALP 및 LDH활성을 유의성있게 감소시키므로서 감잎phenolic compounds가 에탄올에 의한 간세포 손상에 대한 해독 및 보호작용이 있는 것으로 사료된다. To investigate antioxidative effects of phenolic compounds separated from persimmon leaves(PL)(Diospyros kaki Thunb.) on the ethanol-induced hepatotoxicity in rat, Sprague-Dawley rats weighing 100-150 g were divided into 5 groups; control group(CON), PL(70 mg/kg) administered group(PEI), ethanol(5 mL/kg, 25%) administered group(ETH), PL(70 mg/kg) and ethanol administered group (PE2), and PL(140 mg/kg) and ethanol administered group(PE3), respectively. The antioxidative activity of persimmon leaves decreased in order of ethylacetate > interphase materials > n-butanol > chloroform > n-hexane > water fraction. The growth rate and feed efficiency ratio decreased by ethanol were gradually increased to the adjacent level of CON by administering PL. The serum activities of ALT, alkaline phosphatase and lactic acid dehydrogenase elevated by ethanol were decreased significantly. It was also observed that the activities of SOD, catalase, and GSH-Px of rat liver increased by ethanol were markedly decreased in PL administered group as compared to ETH. The GSH content of liver was decreased by ethanol, but that was increase in PEI and PF2 compared with ETH as a dose-dependant manner. These results suggested that phenolic compounds separated from persimmon leaves have a possible protective and relievable effect on the ethanol-induced hepatotoxicity in rats

Computerization means that works such as control, survey and business management are carried out by the way of automation like a computer. Thus we can correctly and rapidly work out a lot of quantity of information with it. It also has advantage of sharing a piece of information with other people by intemet, intranet or other communication means. Although Journal of the Korean Academy of Maxillofacial Plastic and Reconstructive Surgery (JKAMPRS) has published 588 articles from 1962, they are not yet computerized. So it is not easy to make reference and the incidence of its citation is very lower than foreign articles. The purposes of this study are computerization and analysis of articles pattern of the JKAMPRS. Scanner can be used for screening the JKAMPRS from 1995 to 1997 (165 articles). By converting the data through Optical Character Recognition (OCR) software into text file and then linking the data to program called Tool Book publisher thus making it into CD-ROM type and make available screening, downloading and uploading through the internet. After making the software (Article 1.0), topics and number of authors, figures, tables, references and citation of Korean references were classified with Article 1.0 for analyzing the pattern of JKAMPRS . The results obtained were as follow: 1. Of OCR processing, the recognizable rate due to using Chinese and Japanese characters were declined and it took a long time in editing. In writing an article, using of foreign languages has to restrict except English. 2. Format of treatises, particularly figures and tables, is required in a systematic form. 3. As some errors were occurred in search of screening because of similar term, unification of medical term is required to publish the articles. 4. By making CD-ROM and being able to screening in the Internet, it has provided convenience and availability. 5. Most of articles topics were tumor, reconstruction and orthognathic surgery in the Journal of Korean Academy of Maxillofacial Plastic and Reconstructive Surgery. 6. Numbers of authors are 2 to 5 persons in almost articles, but article of single author is not to be enough. 7. It is a general to have about 10 figures and 5 tables in one article. 8. It is adequate to cite from 30 to 40 references. But it is required to actively cite the Korean references.

Dysfunction of the inferior alveolar nerve indicated by various degree of numbness of the lower lip and chin is one of the few drawbacks of mandibular osteotomy, especially Bilateral Sagittal Split Ramus Osteotomy(BSSRO) and genioplasty. Although it has been recorded throughout the history of this techniques, it is true etiology poorly understood. In this study, 22 consecutive patients under class III malocclusiion impression and undergoing orthognathic surgery(BSSRO only 11 case, BSSRO with genioplasty 11 case) were studied using 4 neurosensory test(static light touch, directional discrimination, two-point discrimination, pin pressure nociception) with post OP 1 week, 2 weeks,4 weeks, 8 weeks, 12 weeks, 24 weeks, On control group, 10 members without trauma and nerve damage history, nerve test was accomplished. We concluded majority of patients return of sensation during post operative 24 weeks. Althought immediate nerve deficit are 92.2%, 97.2% 88.9% these are recovered to 25%, 35.72%, 10.71% at 24 weeks. Nerve recovery rate increased prominently between post 4 weeks and 8 weeks. There is no statistically difference about neurosensory deficit among the chin area. Neurosensory deficit more severe when the BSSRO with genioplasty group than the only BSSRO group. Immediate neurosensory deficit is larger left side than right side but after 6 months, there is no significantly difference between left side and right side. Static light touch and pin pressure nociception are more sensitive method of neurosensory deficit than two point discrimination.
