Since the 1970s, the average life expectancy of Koreans has been increasing. Our concerns are not simply about longevity, but also about disability-free life. lately, Sasang constitutional medicine has attracted public attention, especially with respect to the elderly. The purpose of this study was to investigate the food habits, nutrients intake, and disease distribution among the elderly, according to their Sasang constitutions. The results are as follow : The distribution of constitutions of the subjects were Tae-eum 48.8%, So-yang 27.4%, So-eum 22.6%, and So-yang + So-eum 1.2%. In both elderly men and women, body weight, percent ideal body weight, and diastolic pressure of the Tae-eum were significantly higher than those of other constitutions. In both men and women, the level of hemoglobin in the Tae-eum was significantly higher than those of other constitutions. The level of LDL-cholesterol was higher, and the level of HDL-cholesterol was lower in the So-eum elderly women. Food habits of the So-eum were the most irregular, and nutrients intake of the So-eum was lower than that of other constitutions in both elderly men and women. In elderly men, the incidence of hypertension was the highest in the Tae-eum, and the incidence of gastritis was the highest in both So-yang and So-eum. In elderly women, the incidence of fatty liver was the highest in the Tae-eum and So-yang, and gastritis and hypertension were the highest in the So-eum. In the elderly, obese and anemic persons were significantly more in the Tae-eum and the So-eum, respectively. The results of this study showed that there were significant differences of physical, characeristics, food, habits, and distributions of disease for the subjects according to each Sasang constitutions. Intake of nutrient was poor, regardless of Sasang constitutions, in both men and women.

본 연구에서는 가시오가피 추출물의 부위, 추출 용매, 산 가수분해 전처리에 따른 항산화 활성을 알아보고자 FRAP assay를 실시하였으며, 총 페놀 함량을 측정하고, 가시오가피 추출물의 항산화 활성과 총 페놀 함량간의 상관관계를 분석하였다. 또한 가시오가피 추출물 처리가 조골세포 증식률과 alkaline phosphatase 활성에 미치는 영향을 분석하여 가시오가피의 골다공증 예방 가능성을 규명하고자 하였다. 연구결과 가시오가피에 함유된 총 페놀 함량과 FRAP법으로 측정된 항산화 활성 간에 양의 상관관계가 있는 것으로 나타났으므로, 가시오가피의 항산화 활성은 함유된 폴리페놀에 의해 나타나는 것으로 풀이된다. 그러나 가시오가피에 함유된 폴리페놀 함량과 항산화 활성은 가시오가피의 부위와 추출 용매 및 산 처리 여부에 따라 차이가 나는 것으로 나타났다. 또한 가시오가피의 에탄올 추출물이 물 추출물에 비하여 조골세포 증식을 유의적으로 증가시켜주는 것으로 나타났다. 가시오가피의 물 추출물은 조골세포에서 염기성 인산 분해 효소의 활성을 유의적으로 증가 시켰다. 이는 가시오가피의 부위와 추출 용매 및 전처리 과정에 따라 추출되는 활성 성분의 종류와 양에 차이가 있기 때문으로 풀이된다. 이 결과는 가시오가피의 가공법을 선정하는데 고려되어야 할 중요한 사항으로 사료된다. 본 연구를 통하여 가시오가피의 항산화 활성과 조골세포 증식 효과가 제시되었다. 한국산 가시오가피를 건강 기능 식품 소재로 개발하기 위해서는 동물 실험과 인체 시험을 통한 심도 있는 연구가 수행되어야 할 것이다.

The intention of this study was to identify the bacterial pathogens infecting Oreochromis niloticus (Nile tilapia) and Clarias gariepinus (African catfish), and to establish the antibiotic susceptibility of fish bacteria in Uganda. A total of 288 fish samples from 40 fish farms (ponds, cages, and tanks) and 8 wild water sites were aseptically collected and bacteria isolated from the head kidney, liver, brain and spleen. The isolates were identified by their morphological characteristics, conventional biochemical tests and Analytical Profile Index test kits. Antibiotic susceptibility of selected bacteria was determined by the Kirby-Bauer disc diffusion method. The following well-known fish pathogens were identified at a farm prevalence of; Aeromonas hydrophila (43.8%), Aeromonas sobria (20.8%), Edwardsiella tarda (8.3%), Flavobacterium spp. (4.2%) and Streptococcus spp. (6.3%). Other bacteria with varying significance as fish pathogens were also identified including Plesiomonas shigelloides (25.0%), Chryseobacterium indoligenes (12.5%), Pseudomonas fluorescens (10.4%), Pseudomonas aeruginosa (4.2%), Pseudomonas stutzeri (2.1%), Vibrio cholerae (10.4%), Proteus spp. (6.3%), Citrobacter spp. (4.2%), Klebsiella spp. (4.2%) Serratia marcescens (4.2%), Burkholderia cepacia (2.1%), Comamonas testosteroni (8.3%) and Ralstonia picketti (2.1%). Aeromonas spp., Edwardsiella tarda and Streptococcus spp. were commonly isolated from diseased fish. Aeromonas spp. (n = 82) and Plesiomonas shigelloides (n = 73) were evaluated for antibiotic susceptibility. All isolates tested were susceptible to at-least ten (10) of the fourteen antibiotics evaluated. High levels of resistance were however expressed by all isolates to penicillin, oxacillin and ampicillin. This observed resistance is most probably intrinsic to those bacteria, suggesting minimal levels of acquired antibiotic resistance in fish bacteria from the study area. To our knowledge, this is the first study to establish the occurrence of several bacteria species infecting fish; and to determine antibiotic susceptibility of fish bacteria in Uganda. The current study provides baseline information for future reference and fish disease management in the country.

SREBPs는 지질의 항상성 및 대사를 조절하는 전사 인자이다. 이들은 내인성 콜레스테롤, 지방산(FA), 트리아실글리세롤(TG) 및 인지질 합성에 필요한 효소의 발현을 정밀하게 조절한다. 3종류의 SREBP 단백질은 2개의 다른 유전자에 의해 암호화 된다. SREBP1 유전자는 SREBP-1a와 SREBP-1c를 만든다. 이는 RNA의 alternative splicing에 의한 대체 프로모터의 이용으로부터 유도된다. SREBP-2는 별도의 유전자에서 유래한다. 또한, SREBPs는 ER 스트레스, 염증, 자가포식 및 세포사멸과 같은 수많은 병인과정에 관여하며, 비만, 이상 지질혈증, 당뇨병 및 비알콜성 지방간 질환 등을 유발하는 것으로 알려져 있다. 유전체의 분석은 SREBPs가 생물학적 신호 전달, 세포 신진 대사, 및 성장을 조절하는 중요한 연결고리임을 보여 주었다. 이 과정에서 SREBP는 PI3K-Akt-mTOR 경로를 통해 활성화 된다고 알려져 있다. 하지만 정확한 분자 메커니즘은 좀더 밝혀져야 한다. 이 리뷰에서는 세포, 기관 및 생물개체 수준의 생리학 및 병태 생리학 영역에서 SREBP의 역할에 대한 포괄적인 이해를 넓혀 줄 것이다.

Background: The purpose of this research was to examine the fall incidence rate and its related factors of fall in inpatients. Methods: The data were collected from the 138 fall incident reports in one tertiary hospital in Seoul from April 1st 1999 to September 30th 2001. The Fall Incident Report Form was originally developed based on that of Massachusetts General Hospital revised in 1995. And this was modified for this survey by the collaborating work of QI team including researcher and department of nursing service of this particular hospital. The contents of Fall Incident Form were general characteristics of patient. factors related to fall. types and places of fall. circumstances, nursing interventions. and outcome. Results: 1) The incidence rate of fall was 0.08% of total discharged patients and 0.081 per 1000 patient-day. This incidence rate is much lower than that of several hospitals in USA. This finding might result from the different incidence report system of each hospital. 2) The characteristics of fall-prone patient were found as follows. They were mostly over 60 years old, in alert mental status, ambulatory with some assistance, and dependent on ambulatory device. The types of diseases related high incidence rate were cerebrovascular disease(3.2), hypertension(1.6), cardiovascular disease(1.4), diabetes(1.3) and liver disease(0.6). 3) The majority of fall events usually occurred m bed. bedside(walking or standing) and bathroom in patient room. Usually they were up on their own when they fell. And there were more falls of elderly occurred during night time than day or evening. 4) 63.8% of fall events resulted in physical injuries such as fracture and usually the patients had diagnostic procedures and some treatment(ex. suture) which caused additional cost to the patients and their families. 5) The found risk factors of fall were drugs(antihypertensive drug, diuretics) and environmental factors like too high bed height, long distance of bedside table and lamp switch, and slippery tile of bathroom floor. Conclusion: Considering these results, every medical and nursing staff should be aware of the risk factors of patients in hospital, and should intervene more actively the preventive managements, specially for the elderly patients during night. Therefore, it is recommended that the development of Fall Prevention Programs based on these results.

Oxidized low-density lipoprotein (oxLDL) has been shown to modulate transactivations by the peroxisome proliferator activated receptor (PPAR)$\gamma$ and nuclear factor-kappa B (NF$\kappa$B). In this study, the oxLDL signaling pathways involved with the NF$\kappa$B transactivation were investigated by utilizing a reporter construct driven by three upstream NF$\kappa$B binding sites, and various pharmacological inhibitors. OxLDL and its constituent lysophophatidylcholine (lysoPC) induced a rapid and transient increase of intracellular calcium and stimulated the NF-KB transactivation in resting RAW264.7 macrophage cells in an oxidation-dependent manner. The NF$\kappa$B activation by oxLDL or lysoPC was inhibited by protein kinase C inhibitors or an intracellular calcium chelator. Tyrosine kinase or PI3 kinase inhibitors did not block the NF$\kappa$B transactivation. Furthermore, the oxLDL-induced NF$\kappa$B activity was abolished by the PPAR$\gamma$ ligands. When the endocytosis of oxLDL was blocked by cytochalasin B, the NF$\kappa$B transactivation by oxLDL was synergistically increased, while PPAR transactivation was blocked. These results suggest that oxLDL activates NF-$\kappa$B in resting macrophages via protein kinase C- and/or calcium-dependent pathways, which does not involve the endocytic processing of oxLDL. The endocytosis-dependent PPAR$\gamma$ activation by oxLDL may function as an inactivation route of the oxLDL induced NF$\kappa$B signal. Short heterodimer partner (SHP), specifically expressed in liver and a limited number of other tissues, is an unusual orphan nuclear receptor that lacks the conventional DNA-binding domain. In this work, we found that SHP expression is abundant in murine macrophage cell line RAW 264.7 but suppressed by oxLDL and its constituent I3-HODE, a ligand for peroxisome proliferator-activated receptor y. Furthermore, SHP acted as a transcription coactivator of nuclear factor-$\kappa$B (NF$\kappa$B) and was essential for the previously described NF$\kappa$B transactivation by lysoPC, one of the oxLDL constituents. Accordingly, NF$\kappa$B, transcriptionally active in the beginning, became progressively inert in oxLDL-treated RAW 264.7 cells, as oxLDL decreased the SHP expression. Thus, SHP appears to be an important modulatory component to regulate the transcriptional activities of NF$\kappa$B in oxLDL-treated, resting macrophage cells.

In general the prevalence of old people is high and frequently have multiple diseases and symtoms requiring treatment. The nature of illness in the elderly has to be faced, and drugs do have an important part in the treatment of that illness. The purpose of this study were to describe health status and medication, and to provide some basic data for elderly's health education, especially for the right medication. Body mass index, self perceived health status, activities of daily living, disease and experience of past operation were surveyed to recognize the 249 elderly's actual health status. The degree of the elderly's understanding the way of medication, experience of side effects, experience of drug combination and incidence of drug adverse reaction along with drug combination were examined for medication. The aged $women(BMI; 10.7\pm13.3\%)$ overweighed the aged $men(BMI; 4.0\pm10.4\%)$. $69.0\%$ of them recognized their health good. Their activities of daily living were diminished following by the age group(p=0.0068) and relationship with self perceived health status were very significant(p=0.0005). They(192 elderly) suffered from multiple disease such as $osteoarthritis(49.5\%)$, $hypertension(32.0\%)$, gastric $disorder(16.1%)$, $diabetes(14.6\%)$, $osteomalacia(10.9\%)$, cardiovascular $disease(9.9\%)$, senile $cataract(5.7\%)$, skin $rash(5.2\%)$, liver $disease(4.2\%)$, kidney $disease(3.6\%)$, spinal cord $problem(3.6\%)$, respiratory $disease(2.1\%)$ $tuberculosis(1.0\%)\;etc(1.0\%).$ $28.3\%$ of them replied that they had an operation for appendictis senile cataract, peptic ulcer, spinal cord problem, pleurisy, hemorrhoid and the rest. Most of $them(87.4\%)$ knew the way very well how to use drugs, and $21.6\%$ of the replied 171 elderly experienced adverse drug reaction. Drug compliance rate were $high(83.6\%)$. In our study 56.9% of the 167 elderly took several medicine together. And $18.9\%$ of the 95 elderly who did drug combination had an experience of drug interaction. One person kept average 5.5 kinds of drugs at home among 243 elderly. They kept $digestives(79.4\%)$, $ointments(68.7\%)$, $vitamins(59.7\%)$, $analgesics(59.7\%)$, cold $medicines(45.3\%)$ antiarthritic $drugs(33.3\%)$, health $foods(27.7\%)$, antihypertensive $drugs(25.1\%)$, anti peptic ulcer $drugs(24.7\%)$, $laxatives(19.8\%)$, $antacids(16.5\%),\;antibiotics(l6.5\%)$, hypoglycemic $agents(10.3\%)$, cardiac $stimulants(7.0\%)$, $diuretics(4.5\%)$, antiarrhythmic $drugs(4.9\%)$, anti anginal $drugs(4.1\%)$, $hypnotics(3.3\%)$, $etc(38.3\%)$. With this result, we ascertain that polypharmacy in the elderly caused by multiple disease is common, which lead to drug interaction. So our task is to educate elderly how to use drugs in order to maximize their efficiency and to minimize their adverse effects.
