<▼1><P>Although the positive effects of recombinant fibroblast growth factor-2 (rFGF-2) in chronic obstructive pulmonary disease (COPD) have been implicated in previous studies, knowledge of its role in COPD remains limited. The mechanism of FGF2 in a COPD mouse model and the therapeutic potential of rFGF-2 were investigated in COPD. The mechanism and protective effects of rFGF-2 were evaluated in cigarette smoke-exposed or elastase-induced COPD animal models. Inflammation was assessed in alveolar cells and lung tissues from mice. FGF-2 was decreased in the lungs of cigarette smoke-exposed mice. Intranasal use of rFGF-2 significantly reduced macrophage-dominant inflammation and alveolar destruction in the lungs. In the elastase-induced emphysema model, rFGF-2 improved regeneration of the lungs. In humans, plasma FGF-2 was decreased significantly in COPD compared with normal subjects (10 subjects, <I>P</I> <I>=</I> 0.037). The safety and efficacy of inhaled rFGF-2 use was examined in COPD patients, along with changes in respiratory symptoms and pulmonary function. A 2-week treatment with inhaled rFGF-2 in COPD (<I>n</I> = 6) resulted in significantly improved respiratory symptoms compared with baseline levels (<I>P</I> <I><</I> 0.05); however, the results were not significant compared with the placebo. The pulmonary function test results of COPD improved numerically compared with those in the placebo, but the difference was not statistically significant. No serious adverse events occurred during treatment with inhaled rFGF-2. The loss of FGF-2 production is an important mechanism in the development of COPD. Inhaling rFGF-2 may be a new therapeutic option for patients with COPD because rFGF-2 decreases inflammation in lungs exposed to cigarette smoke.</P></▼1><▼2><P><B>Lung disease: Inhaling a protein might help</B></P><P>Studies on the role of the protein ‘fibroblast growth factor-2’ (FGF-2) in chronic obstructive pulmonary disease (COPD) suggest that inhaled FGF-2 could help treat the emphysema linked to smoking. Researchers in South Korea led by Young-Koo Jee at Dankook University, Cheonan, and Yeon-Mok Oh at the University of Ulsan, Seoul, studied the role of the reduced FGF-2 levels found in mice with lung inflammation caused by exposure to cigarette smoke. They also uncovered details of a protective effect of inhaled FGF-2, identifying specific cellular and lung structure changes attributed to the administered FGF-2. Reduced FGF-2 levels were also found in patients with COPD. Initial trials revealed some improvement in patients treated with FGF-2, but not at a statistically significant level. Nevertheless, the authors suggest their results justify further investigation of the protein’s therapeutic potential.</P></▼2>

This study was attempted to examine the effect of Sopung-Tang extract(STE) on anti-inflammatory action in rats, analqesic action and the acute, subacute toxicity in mice. In anti-inflammatory activity in rats, STE was shown to have significant preventive effect in the edema induced by Freund's conplete adjuvant and 5% acetic acid. In analgesic activity in mice, STE was shown to have significant analgesic action on the writhing syndrome in mice induced by 0.7% acetic acid. In acute toxicity test in mice, STE showed 10% mortality at 2000㎎/㎏ . and 1200㎎/㎏ i.p. In subacute toxicity test in mice, STE was not showed for 19 days. Serum uric acid in treated by adjuvant method rats were slightly decreaced by comparing with the control group. During the administration of extracts the body weight increased, but the liver and spleen weight was not changed.

Objectives : In this study, the authors evaluated the correlation between eurocognitive impairments and serum lipids levels among Korean elderly over the age of 65. Methods : A total of 609 elderly individuals participated in this study. Screening for cognitive impairments were carried out using the Mini-Mental Status Examination-Korean version (MMSE-KC). There were 197 subjects above 1.5SD Of MMSE- KC and they were evaluated using the Korean versions of the Consortium to Establish a Registry for Alzheimer's Disease (AD) (CERAD-KC) and Geriatric Depression Scale (GDS-K). Results : There was a correlation between old age/low levels of education and AD (p<0.05, P<0.01). There was an inverse correlation between the serum level of total cholesterol and the word list recognition test scores. The serum levels of LDL cholesterol were inversely correlated with the scores on the constructional praxis test, word list recall test and word list recognition test. Inverse correlations between the serum level of triglyceride and scores on the word list recall test and word list recognition test were also observed. Conclusion : There were inverse correlations between the serum levels of lipids and language/memory function in subjects with AD.

Background and aims: The Apolipoprotein E is a ligand of both the protein component LDL receptor as well as the apo E LDL-Receptor related protein (LRP). It modulates the receptor binding of lipoproteins, with the apolipoprotein E found on cell surfaces as its component, thus serving an important role in the lipid metabolism by carrying out the intracellular transport of cholesterol in lipoproteins. The gene for apolipoprotein E is the product of three common genotypes as well as many more rare alleles. The common genotypes are ε2, ε3, and ε4, and are expressed in the three phenotype isoforms of E2, E3, and E4. In the event that E4 is the main component, a rise in the cholesterol level, as the result of down-regulation of the LDL receptor, is observed. Therefore, those samples with E4 genotypes are known to be in much higher risk of coronary artery disease than those with ε3/ε3, while those with ε2 are in low risk (with the exception of hypertiglyceremai Ⅲ). The aim of this study is to analyze in patients with ischemic heart disease the role of aplipoprotein E alleles in order to seek its correlation with coronary artery disease, as well as to seek whether the polymorphism of apo E produces any differences in the severity of coronary artery disease according to plasma lipid levels. Methods: The subjects for study were 273 patients admitted to the Internal Cardiology Division of the Soonchunhyang University Hospital form December 1998 to February 1999. The subjects were divided into the two groups of which one was ischemic heart disease (IHD) experiment group totaling 105 (avg.60.1 years of age, male/female ratio = 69/36) and the control group totaling 168 (avg. 59.7 years of age, male/female = 73:95). The coronary angiogram was given to 127 subjects, and of this total, 94 have developed significant stenosis in the coronary artery. The stages of the analyzing of the apo E phenotype was first, the separation of DNA from the blood samples, subjecting it to the PCR from with 228 base pairs of expanded products were obtained. The band was determined by means of the reverse hybridization principle on the nitrocellulose strip. Results: From the 105 patients the distributions of apo E phenotypes were as follows: ε3/2(5.7%), ε4/2(1.9%), ε3/3(70%), ε4/3(20%), ε4/4(1.9%). The relative frequencies of each allele are as follow: ε2 (0.038), ε3 (0.833), ε4 (0.128). The results show as follows: ⅰ) The IHD experiment group to have a higher occurrence of ε4/3 phenotypes as well as ε4 alleles than the control group. ⅱ) Both the control group and IHD group showed the largest distribution of ε3/3 for phenotypes, and ε4 for alleles. ⅲ) The IHD group showed less ε2/3 phenotypes as well as significantly less allele frequency of ε3 in comparison to the control group. ⅳ) the IHD group showed a much lower level of HDL in comparison to the control group, while the LDL was significantly higher; samples including the apo ε2 showed a significantly higher level of HDL than those without. Among the control group, samples including apo ε2 showed a significantly higher level of TG (triglyceride) than samples without. No significant difference was found between the experiment apo ε4 sample and the control plasma lipid sample. ⅴ) No significant correlation was found between an apo E polynorphism and the number of involved arteries of a coronary angiogram. Conclusion: Between the experiment IHD group and control group were found differences in the frequency of alleles. The polymorphism of apo E alleles may contribute as a risk factor to the development of heart disease by involving itself in the metabolism and modulation of plasma lipids.

급성 심근염환자에서 발행한 완전 방실차단을 영구 심장박동 조율기로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Myocarditis, an inflammatory process involving the myocardal wall, may be caused by most infectious agents. Irrespective of its etiology, it presents commonly with evidence of heart failure, hypotension, and various electrocardiographic abnormalities. Patient with myocarditis may be asymptomatic or may have a rapidly progressive fatal disease. Medical management of patients with myocarditis includes specific therapy for underlying infection and control of the complication of myocarditis such as congestive heart failure and arrhythmia. Recently we had experienced myocarditis with complete atrioventricular block in 37-year-old man. Although he had shown complete recovery of heart failure, he had shown complete atrioventricular block, so we inserted permanent pacemaker. We report it with review of the literature.
