To evaluate age and gender differences in the relation of cardiovascular risk factors, cognitive impairment, and subclinical carotid atherosclerosis from aged people using by a cross sectional method. Sixty-nine healthy elders living in the community who had not previously undergone carotid ultrasonography were included. We conducted life style surveys, and cognitive function tests including Korean-mini-mental state examination (K-MMSE) and clinical dementia rating-Korean. Various biomarkers from blood were assessed; fasting insulin-like growth factor-1, lipid-profile, high sensitivity C-reactive protein, total homocysteine, glucose, insulin, Homeostasis model assessment (HOMA) for insulin resistance index, vitamin B12, and folate level. Carotid intima-media thickness (C-IMT), and plaques were measured using carotid ultrasonography and aortic ultrasonography, a valid index of atherosclerosis. For the elderly subjects (aged 65-82 years), cognition impairment was more prevalent in females while subclinical atherosclerosis was more prevalentin males. Increased C-IMT has been kept in males, and C-IMT shows increasing trend and the peak at about 80 year-old in females with increasing age. The significant correlations between C-IMT and many vascular risk factors including age, triglyceride, abnormal homocysteinein male, and K-MMSE, insulin, HOMA index and abnormal aortic ultrasonography in female were different in each gender, with the exception of homocysteine (p<0.05). This data suggests that there were differences of age and gender characteristics in terms of subclinical atherosclerosis, cognitive impairment and vascular risk factors in community-living elders. Further larger and longitudinal studies across entire age are required to better understand the effects of risk factors on subclinical atherosclerosis.

It is common to find cerebral infarct and hemorrhage without definite neurologic signs but with lesions on neuroimaging. These lesions are called silent lacunar infarct and cerebral microbleed. Silent lacunar infarct are frequently seen in the elderly and are associated with clinically apparent stroke and vascular dementia. Known stroke risk factors, such as hypertension, diabetes mellitus, smoking, hypercholesterolemia and heart problems may increase the risk of silent lacunar infarct. Metabolic syndrome, homocysteinemia, renal failure and intima media thickness(IMT) are also other risk factors of the silent lacunar infarct. Cerebral microbleed, lacunar infarct and intracerebral hemorrhage(ICH) have similar pathology and pathogenesis. So, cerebral microbleed are coexisted with lacunar infarct, leukoaraiosis, hypertensive ICH and vascular dementia. Cerebral microbleed are associated with volume and recurrence of ICH. Also cerebral microbleed may reflect baseline status of blood brain barrior disruption. Silent lacunar infarct and cerebral microbleed are very important to clinical management, but in the aspect of insurance medicine and independent medical examiners, these lesions are not subject of evaluation for handicap.

"본 논문은 대한내과학회지 2006년 제70권 제3호에 실렸던 논문으로 대한내과학회 편집위원회의 승인을 득하고 본 협회지에 게재함. Background : Diabetes mellitus is a major independent risk factor for atherosclerosis. In recent years non-invasive high resolution B-mode ultrasound methods have been developed to measure the intima-media thickness(IMT) of the carotid artery as an indicator for early atherosclerosis. Itis known that obesity plays a role in the development of type 2 diabetes and cardiovascular disease, and it has also been reported that not only the amount but also the distribution of body fat is important. This study investigated the relationship between obesity and the development of carotid atherosclerosis in type 2 diabetic patients. Methods: Carotid IMT was measured by ultrasound B-mode imaging in 144 patients with type 2diabetes mellitus. All subjects underwent assessment for the degree and distribution of obesity, the presence of coronary artery disease risk factors, and the presence of diabetic complications. Resuts: Carotid IMT was increased in the abdominal obese group defined by waist circurference. However, there was no significant difference in carotid TMT between the non-obese group and obese group as defined by body mass index, waist to hip ratio, and total body fat percent measured by bio electrical impedance analysis. There were positive correlations between carotid IMT and age, duration of diabetes, systolic blood pressure, and waist circumference. Multiple linear regression analysis revealed the variable that interacted independently with carotid IMT was age in type 2 diabetic patients. Carotid IMT was significantly increased in type 2 diabetic patients with macrovascular complications and microvascvlar complications .Conclusion: This study suggested that abdominal obesity rather than general obesity was associated with carotid atherosclerosis reflected by increment of carotid IMT in type 2 diabetic subjects.

The purpose of this study is to investigate hypotensive effect of BDR-29, new herbal preparation of Cassiae Semen, Prunellae Spica, Uncariae Ramulus et Uncus, and Tribuli Semen, in stroke-prone spontaneously hypertensive rats (SHR-SP). SHR-SP were treated with BDR-29 at a dose of 100, 200 mg/kg/day orally for 13 weeks. In the BDR-29 treat group, mean blood pressure and systolic blood pressure were significantly reduced (p<0.05). In phenylephrine-precontracted arota and carotid artery, BDR-29 induced endothelium-dependent vascular relaxation. Hematological findings and biochemical examination revealed no evidence of specific toxicity related to BDR-29. In addition, BDR-29 was markedly attenuated intima-media thickness of thoracic aorta with progression of atherosclerosis. SHR-SP were treated with BDR-29 were significantly increased eNOS expression in arota. These results indicated that BDR-29 improves blood pressure as well as initial atherosclerotic lesion.

Hypertension has been approved to cause disharmony between the heart and kidney such as cardiac hypertrophy and kidney dysfunction. In traditional oriental medicine Paeo-tang (PET) has been shown to have effects on blood circulation improvement. However, the beneficial effect of PET on hypertension remains unknown. In this study, we investigated that PET attenuates blood pressure and improves cardiovascular and renal function in NG-nitro-L-arginine methylester (L-NAME) rat model. Hypertensive rat models were induced by the administration of L-NAME (40 mg/kg/day) and then PET (50 or 100 mg/kg/day) or Olmetec was treated for 2 weeks. PET treatment significantly suppressed the systolic blood pressure and decreased intima-media thickness in the thoracic aorta. PET ameliorated endothelium-dependent and independent vascular relaxation in the L-NAME-induced vascular dysfunction. PET ameliorated the functional decline in the kidney such as albumin and blood urea nitrogen in plasma. These results demonstrated that PET possesses protective effects against L-NAME-induced hypertension.

The plant Dendropanax morbifera Léveille is effective folk medicines for the treatment of several conditions, such as infectious diseases, skin diseases, and other illnesses. Although the inhibitory effects of D. morbifera on the proliferation and migration of vascular smooth muscle cells (VSMCs) have been shown in our previous study, its effects in vivo remain to be elucidated. In this study, we aimed to investigate the protective effects of the extracts from D. morbifera (EDM) on neointimal hyperplasia of rat carotid artery and explore the underlying mechanisms. We observed that the ratio of intima to media thickness (I/M) was significantly decreased in the EDM-treated groups by ~80% compared to that of the control. The expression of Ki-67 and proliferating cell nuclear antigen was decreased by ~70% in the EDM-treated groups compared to that of the control. In addition, matrix metalloproteinase (MMP)2 and MMP9 significantly reduced in the neointimal layer of the EDM-treated groups. Moreover, the decreased levels of contractile phenotypic markers of VSMCs, such as α-smooth muscle actin, myocardin, and smooth muscle-myosin heavy chain, were successfully restored by EDM treatment. Furthermore, the levels of synthetic phenotypic markers, cellular retinal binding protein 1 and connexin 43 were also restored to normal levels. These results suggest that EDM inhibits vascular neointimal hyperplasia induced by balloon injury in rats via phenotypic modulation of VSMCs. Therefore, EDM may be a potential drug candidate for the prevention of restenosis.
