Objective: Rheumatoid arthritis (RA) is associated with an increased cardiovascular events. These may be related to insulin resistance (IR). We evaluated status of IR and analyzed the relationship between IR and clinical and laboratory characteristics in patients with RA. Methods: We examined 52 RA patients (43 females) and 52 age and sex matched healthy controls. We measured Homeostasis model assessment (HOMA) IR, calculated according to fasting serum glucose and insulin. Results: In patients, age was 50.8±10.2 years old, disease duration was 42.1±30.9 months. In controls, HOMA IR was 0.62±0.30 and in patients, it was 1.28±0.50. This difference was highly significant (p<0.001). Patients with early RA (disease duration is less than 36 months) were 28, and established RA (more than 36 months) were 24. HOMA IR was significantly higher in patients with established RA (1.42±0.45) than those with early RA (1.16±0.45) (p=0.03), and significantly correlated with disease duration (r=0.36, p=0.01), BMI (r=0.36, p<0.001), total cumulative prednisolon dose (r=0.34, p=0.01). Disease duration and BMI were independent predictors for HOMA IR (p<0.01, p=0.03). Conclusion: In patients with RA, IR measured by HOMA IR was more significantly increased than that of healthy control and significantly correlated with disease duration, BMI, and total cumulative prednisolon dose; however, the determinants of HOMA IR in RA patients were disease duration and BMI.

Purpose: The purpose of this study was to compare the efficacy of heparin flushing and normal saline flushing in maintaining patency of central venous catheters(CVCs), and to investigate relative risk factors of CVCs' occlusion. Method: A total of 159 patients who had been inserted with CVCs were included in the department of hemato-oncology of S hospital. The heparin group consisted of 74 patients with 10u/ml diluted heparin flushing from 23 November 2004 to 15 January 2005, and the normal saline group consisted of 85 patients with 0.9% normal saline flushing from 19 January to 31 March of 2005. Result: The heparin group was significantly different from the normal saline group in CVCs' occlusion. The normal saline group offered a much longer survival duration of CVCs' patency than the heparin group. Potential bleeding signs (PT, aPTT) had no significant differences. In multivariate analysis, 0.9% normal saline (hazard ratio 0.50), chemo port (hazard ratio 3.38), and no administration of TPN (hazard ratio 0.25) were the significant factors for occlusion of CVCs. Conclusion: For maintaining the patency of CVCs, 0.9% normal saline flushing are expected to be effective in reducing drug incompatibilities, lessening the bleeding tendency and improving cost effectiveness .

Min-Sang Cha,Sang-Woon Lee,Yoon-Hyuk Huh2,Lee-Ra Cho2,Chan-Jin Park 대한치과보철학회 2017 The Journal of Advanced Prosthodontics Vol.9 No.2

In restorative treatment using fixed dental prostheses, dentists should select appropriate restoration material among various types of dental materials. The strength, marginal fit, esthetics, wear resistance, biocompatibility, and cost are important factors in the choice of restoration materials. The present case showed a surface stain on a monolithic zirconia restoration that was due to wear between the monolithic zirconia restoration and the base metal alloy restoration. This phenomenon was confirmed by surface roughness measurement and electron probe micro-analysis.

Perilla frutescens var. japonica and rosmarinic acid improve amyloid-β<SUB>25-35</SUB> induced impairment of cognition and memory function

Ah Young Lee,Bo Ra Hwang,Myoung Hee Lee,Sanghyun Lee,Eun Ju Cho 대한지역사회영양학회 2016 Nutrition Research and Practice Vol.10 No.3

BACKGROUND/OBJECTIVES: The accumulation of amyloid-β (Aβ) in the brain is a hallmark of Alzheimer’s disease (AD) and plays a key role in cognitive dysfunction. Perilla frutescens var. japonica extract (PFE) and its major compound, rosmarinic acid (RA), have shown antioxidant and anti-inflammatory activities. We investigated whether administration of PFE and RA contributes to cognitive improvement in an Aβ25-35-injected mouse model. MATERIALS/METHODS: Male ICR mice were intracerebroventricularly injected with aggregated Aβ25-35 to induce AD. Aβ25-35-injected mice were fed PFE (50 mg/kg/day) or RA (0.25 mg/kg/day) for 14 days and examined for learning and memory ability through the T-maze, object recognition, and Morris water maze test. RESULTS: Our present study demonstrated that PFE and RA administration significantly enhanced cognition function and object discrimination, which were impaired by Aβ25-35, in the T-maze and object recognition tests, respectively. In addition, oral administration of PFE and RA decreased the time to reach the platform and increased the number of crossings over the removed platform when compared with the Aβ25-35-induced control group in the Morris water maze test. Furthermore, PFE and RA significantly decreased the levels of nitric oxide (NO) and malondialdehyde (MDA) in the brain, kidney, and liver. In particular, PFE markedly attenuated oxidative stress by inhibiting production of NO and MDA in the Aβ25-35-injected mouse brain. CONCLUSIONS: These results suggest that PFE and its active compound RA have beneficial effects on cognitive improvement and may help prevent AD induced by Aβ.

배경: 섬유근육통은 전신의 근골격계 통증과 다양한 신체적, 정신적 복합 증상을 동반하는 만성 질환이다. 섬유근육통은 발병 원인이 뚜렷하지 않고, 임상적으로 만성적인 경과를 거치므로 근치적 치료보다는 대증적 치료가 주를 이루고 있다. 이 연구에서는 섬유근육통 환자에서 아데노 신삼인산(adenosine triphosphate, ATP) 정맥 투여 전 후를 비교하여 ATP 정맥주사요법이 섬유근육통 환자에서 통 증과 피로 개선에 미치는 효과를 알아보고자 한다. 방법: 2017년 6월 1일부터 2017년 7월 30일까지 연구가 수행되는 동안 강남세브란스병원의 가정의학과에 내원하여 섬유근육통이 진단되고 연구 참여에 동의한 19세 이상 65세 미만의 여성 환자 24명을 대상으로 매주 1회씩, 총 2회의 ATP 정맥주사요법을 시행하였다. 정맥주사요법 시행 전과 1회, 2회 시행 후 통증 및 피로도 개선 여부는 ATP 정맥주사요법 전후의 숫자통증강도척도(numeric pain intensity scale, NPS), 섬유근육통영향척도(fibromyalgia impact questionnaire, FIQ), 전신통증지수(widespread pain index, WPI), 증상중증도척도(symptom severity scale, SS), 피로감중증도점수(fatigue severity score, FSS)를 반복측정분산분석으로 분석하였다. 결과: 연구 참가자의 평균 연령은 49.29세였다. 중도 탈락자는 없었으며, 24명을 최종 대상으로 결과를 분석하였다. 5개의 통증 및 피로도 척도 중에서 전신통증지수(WPI)를 제외한 숫자통증강도척도(NPS), 섬유근육통영향척도(FIQ), 증상중증도(SS), 피로감중증도점수(FSS) 4개 항목의 점수가 감소하였다. 특히, 통증, 수면장애, 기분, 삶의 질을 포괄하는 섬유근육통영향척도(FIQ)는 63.08±15.03에서 47.92±17.84로 호전되었다(P=0.004). 결론: 섬유근육통 여성 환자에게 ATP 정맥주사를 투여 후 통증 및 피로도 척도가 호전되었다. Background: Fibromyalgia is characterized by chronic, widespread, musculoskeletal pain accompanied by fatigue, psychiatric symptoms and multiple somatic symptoms. Treatments for fibromyalgia include various pharmacological and non-pharmacologic therapies to minimize symptoms and improving general health. This study aimed to investigate the effect of intravenous adenosine triphosphate (ATP) injection on pain and fatigue in female patients with fibromyalgia. Methods: This study included 24 females who visited the department of family medicine at Gangnam Severance Hospital in Seoul, Korea from June 1, 2017 to July 30, 2017. The participants received ATP injection twice a week apart and they conducted questionnaire survey concerning the severity of pain and fatigue scores such as numeric pain intensity scale (NPS), fibromyalgia impact questionnaire (FIQ), widespread pain index (WPI), symptom severity scale (SS), fatigue severity score (FSS) at the initial (0 week), 1st (1 week), and final (2 weeks) visits. The changes of five symptom scores were compared with repeated measures analysis of variance test. Results: The average age of patients was 49.29±8.52 years. Compared with the symptom scores before ATP injection, most of the pain and fatigue scores except WPI were significantly decreased after ATP injection (All P-values<0.05). In particular, FIQ, which is a comprehensive questionnaire to assess pain, sleep disturbance, mood and quality of life of fibromyalgia, was remarkably decreased from 63.08±15.03 to 47.92±17.84 (P=0.004). Conclusion: Our results suggest that ATP injection may be helpful to improve the severity of pain and fatigue scores pain in female patients with fibromyalgia.

Scavenging Effect of Extract from Perilla frutescens and Rosmarinic Acid from Free Radical and Lipid Peroxidation

Ting Ting Wu,Bo Ra Hwang,Eun Ju Cho 한국식품영양과학회 2011 Preventive Nutrition and Food Science Vol.16 No.3

The radical scavenging activity and inhibition effect from lipid peroxidation induced by peroxyl radical of methanol extract from Perilla frutescens and its active compound, rosmarinic acid (RA), were investigated in vitro. The treatment of extract and RA scavenged 1,1-diphenyl-2-picrylhydrazyl, hydroxyl radical (·OH) and nitric oxide in a concentration-dependent manner. In particular, the extract and RA showed strong radical scavenging activity against ·OH, the most toxic and reactive radical. In addition, Perilla frutescens and RA effectively inhibited lipid oxidation induced by sodium nitroprusside and 2, 2'-azobis(2-aminopropane) dihydrochloride, determined by the ferric thiocyanate method. The present results suggest that Perilla frutescens and RA play a protective role against oxidative stress induced by free radical and lipid peroxidation.

Objective: To quantify the soluble Fas ligand (sFasL) and to measure FasL-Fas complex and FasL-IgG complex in the sera of patients with various rheumatic diseases: systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), systemic sclerosis (SSc), and adult onset Still`s disease (AOSD). Methods: Serum samples were obtained from 37 patients with SLE, 40 with RA, 30 with SSc, 20 with AOSD, and 40 healthy controls. The serum sFasL, FasL-Fas complex, and FasL-IgG complex were measured using a sandwich enzyme-linked immunoabsorbent assay. Hospital medical records were retrospectively reviewed for clinical and laboratory characteristics in patients with SLE. Disease activity in SLE patients was assessed by the SLE Disease Activity Index (SLEDAI) score. Results: In patients with SLE, serum sFasL levels (383.1±208.9pg/ml) were significantly higher (p<0.001) than those of healthy controls (192.0±84.7pg/ml). sFasL levels in patients with RA (150.8±30.7pg/ml, p=0.014), SSc (115.4±13.5pg/ml, p<0.001), and AOSD (137.5±12.9pg/ml, p=0.001) were significantly lower compared with healthy controls. The frequencies of positive FasL-Fas complex and FasL-IgG complex were higher in patients with SLE (56.8%, 56.8% respectively) than in healthy controls (2.5%, 0% respectively) (p<0.001). All patients with RA or AOSD were negative for FasL-Fas complex and FasL-IgG complex. No patients with SSc were positive for FasL-Fas complex. On the other hand, the positive frequency of FasL-IgG complex was greater in patients with SSc (16.7%) than in healthy controls (0%) (p=0.012). Serum levels of FasL-IgG complexes in active SLE patients (OD 0.467±0.050) were tended to be lower than those in inactive SLE patients (OD 0.509±0.055) (p=0.060). SLEDAI score was tended to be negatively correlated with the serum levels of FasL-IgG complex in patients with SLE (r=-0.308, p=0.068). Conclusion: These results suggest that FasL may possibly play a role in the pathogenesis of SLE.
