본 연구는 노화의 정도에 따라 적혈구를 분리하고 장시간의 운동 스트레스가 노화에 미치는 영향을 알아 보고자, 고도로 훈련된 남자 마라톤 선수 3명을 대상으로 HRmax 80% 수준에서 지속적인 런닝을 실시하였다. 전혈에서 RBC, WBC, MCV, Hb, Hct를 측정하고, 적혈구 내에 존재하는 Protein Carboxyl O-Methyltransferase(PCM)을 정제하여 그 activity를 측정하고, 적혈구 막을 분리하여 그 구성 단백질에 대한 PCM 의 Methylatability를 측정하여 운동과 적혈구 노화와의 관계를 설명하고자 한다. 각 시간별, Rest(0분), Running(30, 60, 90, 120분), Recovery(10, 30분)에 혈액을 채혈하여, 전혈에서 RBC, WBC, MCV, Hb, Hct의 변화를 조사하고 (Hematology Analyzer 5), 적혈구를 분리하여 50% Prcoll과 0.154M Hypaque에 넣고 22,000??g에서 40분간 원심분리하면 11 -15개 정도의 적혈구 층이 노화된 정도에 따라 분류된다. 적혈구 세포내의 PCM을 정제하고, 적혈구 막(ghost)을 분리하여 방사성 동위원소 (??C-SAM)를 methyl donor로 하여 PCM activity와 적혈구 막에 대한 Methylatability를 측정하였다. 런닝 30분에 RBC수가 증가하였으며, WBC와 Hb은 운동하는 동안 높은 수준을 유지하였다. MCV와 Hct는 변화가 없었다. Percoll과 Hypaque를 이용하여 노화된 정도에 따라 적혈구를 분류하였으나, 각 층에 대한 세포수의 측정이 뒤따르지 못하여 적혈구 수의 증가 혹은 감소와의 관계를 직접 볼수 없었다. 적혈구 내에서 정제된 PCM activity 는 운동 스트레스에 의한 변화를 보이지 않음으로써 항상 full을 유지하고 있음을 알 수 있다. 적혈구 막에 대한 Methlatability변화는 운동전 26.77±0.32 units/mg.min에서 런닝 30분에 34.29±0.55 units/mg.min로 큰 증가를 보였으며 런닝하는 동안 높은 수준을 유지하였다. 이는 운동 스트레스가 적혈구 막단백질을 구성하는 아미노산에 영향을 미쳐 비정상의 L-isoaspartyl 잔기를 만들었음을 말해주는 것이며, 이것이 노화된 단백질의 수복기전과 일치한다. 즉 PCM이 비정상의 L-isoaspartyl 잔기를 메칠화시켜 정상의 L-aspartyl잔기로 수복시킴으로써 운동 스트레스에 의한 영향을 극복하고자 하는 것이다. 그러므로 장시간의 운동 스트레스가 주는 영향이 노화에 의한 현상과 일치함을 알수 있다. Our studies showed the separation method of erythrocyte according to aging process and the effect that influenced a long-time exercise stress to aging. Highly trained marathon runners (n=3) performed a prolonged running(2hours) at the level of HRmax 80% RBC,WBC,MCV, Hct was measured in a whole blood.Protein Carboxyl O-Methyltransferase(PCM) in the erythrocyte was purified from the cytosol and the activity was measured. Methylatability of erythrocyte membrance protein was measured during marathon performance and recovery phase. Therefore, we interpreted the relation of exercise and erthrocyte aging. The count of RBC increased at the running 30 min. WBC and Hb maintained at the high level during marathon running. MCV and Hct did not changed. Erythrocyte divided into 11-15bands by Percoll and Hypaque according to aging. Because the erythrocyte did not count numerically in different age-related fraction of human erythrocyte, we cannot show the change of erythrocyte count. PCM activity purified in erythrocyte did not change by exercise stress, this suggests that PCM is full at all times. Methylatability of erythrocyte membrane protein changed from 26.77±0.32 units/mg.min before exercise to 34.29±0.55 units/mg.min at 30min after exercise and maintained a high level of methylatability during a running. This suggests that abnormal L-isoaspartyl residues came into being in the membrane protein composition as a result of exercise stress and are repaired by the same mechanism as aging repair that is, PCM methylated abnormal L-isoaspartyl residues in membrane protein and repaired into normal L-aspartyl residues, which removed the effect of exercise stress. Therefore, this study showed that the effect by exercise stress is the same as that of aging process.

정성균,김수일,양은진,류택근,권오유,박경란,이영호,김원식 충남대학교 의과대학 지역사회의학연구소 1998 충남의대잡지 Vol.25 No.2

Injury to peripheral nerve somtimes lead to neuropathic pain. Nitric oxide(NO) is increased in the dorsal root ganglia (DRG) of neuropathic pain models, and L-NAME, a nitric oxide synthase (NOS) inhibitor, reduces neuropathic pain. However, it is not known that underlying mechanism of NO involvement in development and maintanence of neuropathic pain. It was found that there were three NOS isoforms-nNOS, eNOS, and iNOS. It is also necessary to investigate NOS isoforms in neuropathic pain. The aim of this study is to investigate NOS isoforms and NADPH-diaphorase expressions and underlying mechanism of NO involvement in neuropathic pain. The 5^th lambar (L5) DRG were obtaind after tight ligation of L5 an L6 spinal nerves for 7 days. Toluidine blue stain, immunohistochemistry for nNOS, eNOS, and iNOS, and NADPH-diaphorase histochemistry were performed. All specimens were observed under light microscope. nNOS expression was increased significantly in the cytoplasm of the DRG of ligated side at 7 day post-ligation (7D PL). eNOS expression was also increased in the blood vessel, a few neurons or satellite cells, and cell membrane of Schwann cells in the DRG of ligated side at 7D PL. iNOS expression was increased in a few blood vessels and cytoplasm of small neurons in the DRG of ligated side at 7D PL. NADPH-diaphorase expression was increased significantly in the neurons of the DRG of ligate side at 7D PL, but NADPH-diaphorase expressions were weak or absent in the blood vessel and Schwann cell in the contralateral DRG and the DRG of ligated side at 7D PL. It is suggested that NOS isoforms may be closely related to development and mantanence of neuropathic pain in order of nNOS>eNOS>iNOS.

This study was to determine related factors of recurrent falls among the home-dwelling elderly. A sample is 1,902 (male 1,055, female 847) who are over 65 years old. This study used data extracted from the Korean Longitudinal Study of Aging (KLoSA) by the Korea Labor Institute. Univariate analyses were done using chi-square for associated factors of associated factors of recurrent falls and multivariate logistic regression analyses were used for risk factors of recurrent falls. Only 63(3.3%) elderly had experienced recurrent falls last two years of period in panel data. There was a significant difference between elderly who fell recurrently and those who did not with regard to gender, having a spouse, chronic disease, regular medication, depression, ADL limitation, perceived health status, and fear of falling. The risk factors for recurrent falls were ADL limitation and fear of falling. In this study, an ADL limitation and fear of falling were significant factors that differentiated refallers and non-refallers. Therefore, an effective fall prevention program should be focused on multiple risk factor intervention with modifiable components for the elderly.

Purpose : Health Risk behaviors are a leading cause of preventable morbidity and mortality. Adolescents is a critical transitional period for establishing health behavior for healthy life. The purpose of this study was to describe the types and frequency of the health risk behaviors being performed by middle school students, examine the gender and grade differences of health risk behaviors, and identify the relationship among health risk behaviors. Methods : A total of 1952 early adolescents recruited from 7 middle schools in a district of urban setting completed questionnaires. Youth Risk Behavior Survey-Middle school questionnaires was used to identify the types of health risk behaviors among early adolescents. Data were analyzed by descriptive statistics and Chi-Square test using SAS program . Results : The results showed the frequency for most health risk behaviors and increased with advancing grade level. Males were more likely than females to behaviors related to smoking and violence, whereas females were more likely than males to have suicidal thoughts, be physical inactive and attempt to lose weight. Among health risk behaviors, the relationship of alcohol experience, smoking, and suicide was high. Conclusion : The findings identify a high risk target group among middle school adolescents and suggest that preventive intervention strategies should take into consideration the types with gender and grade, and provided the evidence that one of health risk behaviors may induce the other health risk behaviors.

Purpose : The aging population is the quickly increasing in Korea. Since 2008, the National Long term Care Insurance, a number of long term care facilities have established during short time in Korea. Especially, the environmental assessment tool is important for managing healing environment in a long term care facility for the elderly. Alzheimer`s Garden Audit Tool (AGAT) is used to assess whether a garden incorporates those elements and qualities as healing outdoor space. In this paper, we discuss the benefits, limitations, and future directions of the assessment tool for long-term care facilities. Methods : The AGAT audit was done through content analysis by 5 experts from diverse discipline as post occupancy evaluation of a long term care facility located in suburban area. The expert group was asked to describe their comments for modification and improvement in application of AGAT. Results : The results of this study show that it is necessary to refine the instrument`s items to better meet the needs of the criteria and items for Korean culture-friendly tool. Especially, greenhouse elements (various plants, birds etc.), multisensory experiences, users-oriented space, programmed activities in garden, and hazards on pathway has somewhat limitation as measurement to assess outdoor of long-term care facilities in Korea. Implications : Consequently, AGAT could be applicable to evaluate the outdoor space of long term care facility in Korea with culturally sensitive revision.
