  • Clusterin is an 80 kDa heterodimetric glycosylated protein and it plays diverse biological roles in various tissues and organs. Clusterin is reported to be associated with the pathogenesis of coronary artery disease and atherosclerosis. Therefore, we investigated the genotype for the A/G polymorphism at the position 4,183 of clusterin gene in Koreans and compared genotype of patients with control group. 100 patients (Male 63, Female 37), who previously underwent coronary artery stent due to ischemic heart disease and 100 controls (Male 36, Female 64) participated in this study. There was a significant association between 4,183 A/G polymorphism in clusterin gene and coronary artery disease (CAD). The present study shows that clusterin gene A/G polymorphism may be associated with the pathogenesis of CAD. Further studies with larger population may be needed for the development of diagnostic methods at genetic level such as DNA chip.

  • 관상동맥류는 비교적 드문 질환으로 내과적 또는 수술적 치료방법에 대해서는 논란이 있다. 관상동맥류의 원인으로는 동맥경화증, 가와사키병, 염증성 혈관질환, 결체조직질환 및 선천선 기형 등이 있다. 본원에서는 50세 남자환자가 관상동맥 조영술 시행 결과 다혈관 관상동맥류를 진단받고 관상동맥 우회로술을 시행하였기에 문헌고찰과 함께 보고하는 바이다.

  • The regulation of plasma lipid level, particularly LDL cholesterol, represents the focus of current therapy for atherosclerosis. And $Lp-PLA_2$ is able to hydrolyse oxidized phosphatidylcholine within LDL into lyso-PC and oxidized fatty acids. $Lp-PLA_2$ is a potential biomarker of coronary heart disease and plays an important proinflammatory role in the progression of atherosclerosis. We investigated the inhibitory effects of methanol extracts of 224 natural plants on $Lp-PLA_2$ activity. Seven kinds of methanol extracts of tested plants showed above 50% inhibitory effect with the concentration of $100\;{\mu}g/ml$. The concentrated aqueous suspensions of each methanol extract were partitioned with n-hexane, $CHCl_3$, and EtOAc. Among them, EtOAc extracts of Astilbe chinensis var. davidii (root) and Pourthiaea villosa var. brunnea (leaf) significantly inhibited $Lp-PLA_2$ activity at the same concentration.

  • Lipoprotein-associated phospholipase $A_2\;(Lp-PLA_2)$ is a potential biomarker of coronary heart disease and plays an important proinflammatory role in the progression of atherosclerosis. Also acyl-CoA: cholesterol acyltransferase (ACAT) and oxidized low-density lipoprotein (LDL) playa key role in atherosclerosis, respectively. And so, the inhibitory activities of the methanol extracts of 42 insect resources were examined on $Lp-PLA_2$, ACAT, and LDL oxidation for screening of anti-atherogenic substances. Among them, the methanol extracts of Eurydema rugosa significantly inhibited all of upper three activities. Several kinds of tested insects having high inhibitory effect with the methanol extracts were extracted with n-hexane, ethyl acetate, and acetone, and their inhibitory activities were tested.

  • 환아는 3개월된 영아로 발병 10일째에 본원에 내원하여 초기에 적절한 진단과 치료를 받지 못했으며 발병 2주에 시행한 심초음파상 거대 관상동맥류를 보였다. 이에 정맥용 면역글로불린 투여와 aspirin과 dipyridamole로 치료 중 발병 24일째 혈전증이 동반되어 urokinase와 heparin의 IV 투여를 통한 혈전용해 치료로 혈전을 완전히 제거할 수 있었다. 이후 5년간 aspirin, dipyridamole, coumadin을 투여하면서 심전도와 심초음파검사를 반복하며 외래 추적 관찰 중 점차 좌측관상동맥내 혈전이 증가하고 내경이 점차 좁아지는 소견과 함께 협착이 의심되었다. 발병 5년 후 시행한 관상동맥 혈관조영술상 관상동맥 좌측 전하지가 완전 폐색되고 우측관상동맥으로부터 발달한 측부순환에서 혈류를 공급받고 있었고, 핵의학 검사상 좌심실의 전벽과 중격, 일부 외벽에 완전 가역적 관류 결손을 보였던 가와사끼병 환아 1례를 경험하여 보고한다.

  • Objectives: Epicardial fat is true visceral fat that is known to be associated with metabolic syndrome, high abdominal fat, insulin resistance, coronary artery diseases, low coronary flow reserve and subclinical atherosclerosis. Dampness-Phlegm pattern is one of the pattern diagnosis of traditional Korean medicine. Previous studies showed that Dampness-Phlegm pattern is associated with hypertension, dyslipidemia, metabolic syndrome. This study is intended to find association between Dampness-Phlegm pattern and epicardial fat thickness. Methods: This study was a community-based single center trial. Ischemic stroke patients within 30 days after their ictus were enrolled. Epicardial fat thickness was measured using transthoracic echocardiography. Other measured and obtained variables are medical history, weight, height, body mass index, fasting blood glucose, cholesterol, triglycerol, high density lipoprotein, lipid and low density lipoprotein. Results: Three hundred sixty six were enlisted, and one hundred forty were diagnosed with the Dampness-Phlegm pattern. Dampness-Phlegm pattern group had significantly thicker epicardial fat. Binary logistic regression also showed statistically significant result. Conclusions: This study showed close association between epicardial fat and Dampness-Phlegm pattern. This result suggests a clue to standardization of pattern identification.

  • This study was performed to investigate the induction of experimental atherosclerosis in rats and inhibitory effects of aloe vera on progression of atherosclerosis in rats. Adose range finding study of cholesterol and vitamin D2 for the induction of atherosclerosis and studies on the subchronic effect of aloe vera and on the chronic effect of aloe vera were carried out. A total of 3-week old 125 male rats of Sprague-Dawley were divided into 25 groups and fed with the diet containing cholesterol (0.1, 0.2, 0.3, 0.5, 1.0 and 2.0%) and vitamin D2 (500, 5000, 50000 and 500, 000 IU/100 g) for 4 weeks. 35 male rats were divided into 7 groups and fed with the diet containing aloe vera with 1.0% of cholesterol and 50, 000 IU/100 g of vitamin D2 for 4 weeks. 200 male rats were divided into 5 groups and fed with cholesterol and vitamin D2 for 6 and 12 months. Growth, clinical and pathological changes of rats in the three experiments were observed. The results were as follows: 1. In the dose-range finding study, feed intake, feed efficiency ratio and weight to body weight were increased in all of the feed groups containing 500, 000 IU/100 g of vitamin D2. Serum biochemical values of total cholesterol, high-density lipiprotein cholesterol (HDL-cholesterol), triglyceride, calcium, inorganic phosphorous and chloride of male rats in treated groups. The aorta and coronary artery of rats in all of the diet group containing 500, 000 IU/100 g of vitamin D2 showed typical atherosclerotic lesions. 2. Male rats fed with the diet containing aloe vera with 1.0% cholesterol and 50, 000 IU/100 g of vitamin D2 for 6 and 12 months did not show significant difference of diet intake and weight gain, and relative organ weight. The level of serum HDL-cholesterol and triglyceride recovered to the normal range by the aloe vera ingestation. 3. The aorta showed irregular appearence in the tunica intima with swelling, necrosis and calcification. The aorta of rat fed aloe vera diet showed no pathological lesions such as atherosclerosis of aorta. Aloe vera could have a helpful effect of vitamin D2 and cholesterol induced atherosclerosis in rats. Long-term supplementation of aloe vera may slow down the process of experimental atherosclerosis in rats have effects on the development of atherosclerosis.

  • 협심증, 심근경색과 같은 관상동맥 질환은 급속도로 증가하고 있다. 관상동맥 질환은 콜레스테롤과 칼슘과 같은 플라크들이 혈관벽에 흡착되어 발생한다. 심혈관 중재시술은 풍선 카테터와 금속스텐트를 이용하여 좁아진 관상동맥혈관을 확장시키는 비수술적 시술방법이다. 금속재질의 스텐트는 관상동맥질환에 의한 사망자를 감소시키는데 효과적이었지만 영구적으로 혈관에 금속재질 스텐트가 이식되어 있기 때문에 지속적인 염증과 후기 혈전증 등이 발생되었다. 따라서, 스텐트와 같은 영구적 보철물에 의한 합병증과 재협착 등을 해결하기 위한 생체 흡수성 혈관 지지체의 개발은 급속도로 증가되고 있다. 이 리뷰에서는 생체흡수형스텐트의 성공적인 개발을 위한 동향에 대해서 논하고자 한다.
