This study was aimed to investigate the electrolytes and its relationship with acute stroke patients in each stroke type by case-control study. 217 patients with first-ever acute stroke within 2 weeks as the case group(Cases), 146 people without four major risk factors(hypertension, diabetes mellitus, hyperlipidema and ischemic heart disease) as the healthy control group(Normals), and 160 people as the general control group(Controls) were recruited at the Stroke Medical Center in Daejeon University Oriental Medicine Hospital from july 2005 to march 2007 for this case-control study. We analyzed the odds ratio of electrolytes in binary logistic analysis and evaluated each stroke type and general characteristics such as age, sex etc. The level of sodium(Na+) and potassium(K+) were significantly lower in LAA, SVO type of ischemic stroke and hemorrhagic stroke. But the level of chloride(Cl-) had no significant relation with stroke occurance. In this study we demonstrated that low sodium(Na+) and potassium(K+) have an influence on stoke occurance than chloride(Cl-). And we think that the electrolytes must be considered in risk factors of ischemic stroke in Korean and more prospective studies are needed.

Background : Vascular dementia occurs mainly due to cerebral vascular disease. So we performed this clinical study to investigate the incidence and characteristics of vascular dementia in stroke patients. Methods : This study was performed on the patients hospitalized from April 1, 1998 to August 31, 1998 at the department of circulatory internal medicine, hospital of Oriental medicine, Kyung-Hee University, and diagnosed cerebral infarction or hemorrhage by Brain CT or MRI. we devided the patients into two groups; vascular dementia group and non dementia group according to MMSE-K(Mini Mental State Examination Korean version), Hasegawa dementia scale. Patients were diagnosed dementia using DSM-IV. We compared general characteristics, stoke types and laboratory findings between the two groups and investigated the correlationship between MMSE-K and Hasegawa dementia scale. Results : Results showed that the incidence of vascular dementia was about 27.8% in stroke patients. The greater number of subjects with dementia were women in the lower educational classes and had lower MBI(Moderfied Bathel Index) scores. Vascular dementia were more common in patients with large brain lesion size($>20cm^3$). There was a positive correlationship between Hasegawa scores and MMSE-K.

Objectives : A human being is classified into 4 constitutions(Taeyangin, Soyangin, Taeumin, and Souemin) and each constitution has the different incidence, treatment and prevention of disease in Sasang Constutional Medicine[SCM], The purpose of this study is to find relative risk(RR)s of each risk factors including Sasang Constitution[SC] for incidence of ischemic stroke. Methods : In 344-case patients with ischemic stroke and 1446 healthy control subjects without ischemic stroke, we evaluated sex, age. height, weight, BMI, ECG abnormality, hypertension, diabetes mellitus, blood lipid level and SC. These data were statistically analysed to investigate the relations between risk factors and the incidence of ischemic stroke by chi-square test. And then significant factors were analysed to get each adjusted odds ratio[OR] by binary logistic regression analysis. Results : ECG abnormality, hypertension, diabetes mellitus, HDL(high density lipoprotein) cholesterol, and SC were significantly related to the incidence of ischemic stroke, while age, sex and BMI were adjusted in a binary logistic regression analysis. Especially in SC, the incidence of ischemic stoke in Tae-eumin and Soyangin were higher than that in Soeumin (Tae-eumin OR=11.68[95% CI: 6.26-21.80], Soyangin OR=4.64[95% CI: 2.66-8.10]). Conclusions : These results suggested that SC may be one of important risk factors for ischemic stroke and it should be a useful data for prediction of incidence of ischemic stroke.

This study was carried out during 3 years from March 1992 to March 1995, 140 healthy people and 140 C.V.A patients were investigated, at an oriental clinic in Taejon. The data collected was analysed using a SAS. The results are as follows. 1. The Relationships between patients who have undergone one or more abortion procedures and C.V.A occurrence. A statistical significant difference was recorded between the control group and the outpatients group of P<0.05 2. Number of years after initial C.V.A diagnosis before C.V.A symptom onset. within 1 years 52% (2-3 years, 3-4 years, 4-5 years, 5 years and over) 3. Additional diseases occurring after initial stroke 1 disease 50.7% (2, 3, 4, 5 or more) 4. Alcohol Consumption "A statistical significant difference was recorded between the control group and the outpatients group of" P<0.01 5. Previous Treatment Experience for stoke outpatients Oriental Hospital, clinic 64.3% (General Hospital, clinic, a public health center drug store, home remedies, etc) 6. Exercise Frequency Outpatients Regular 28.6%, Irregular 71.4% Control sample Regular 27%, Irregular 72.9% 7. Degree of Appetite "A statistical significant difference was recorded between the control group and the outpatients group of" P<0.01 8. People who include fish in their diet "A statistical difference was recorded between the control group and the outpatients group of" P<0.01.

Background: The vasoconstrictive effect of epinephrine in local anesthetics affects the heart, which leads to hesitation among dentists in injecting local anesthetics into patients with cardiovascular disease. Due to its vasoconstrictive effects, the present study investigated the effects of vasopressin administration on cardiac function in rats. Methods: Experiment 1 aimed to determine the vasopressin concentration that could affect cardiac function. An arterial catheter was inserted into the male Wistar rats. Next, 0.03, 0.3, and 3.0 U/mL arginine vasopressin (AVP) (0.03V, 0.3V, and 3.0V) was injected into the tongue, and the blood pressure was measured. The control group received normal saline only. In Experiment 2, following anesthesia infiltration, a pressure-volume catheter was placed in the left ventricle. Baseline values of end-systolic elastance, end-diastolic volume, end-systolic pressure, stroke work, stroke volume, and end-systolic elastance were recorded. Next, normal saline and 3.0V AVP were injected into the tongue to measure their effect on hemodynamic and cardiac function. Results: After 3.0V administration, systolic blood pressures at 10 and 15 min were higher than those of the control group; they increased at 10 min compared with those at baseline. The diastolic blood pressures at 5-15 min were higher than those of the control group; they increased at 5 and 10 min compared with those at baseline. The preload decreased at 5 and 10 min compared to that at baseline. However, the afterload increased from 5 to 15 min compared with that of the control group; it increased at 10 min compared with that at baseline. Stroke volume decreased at 10 and 15 min compared with that of the control group; it decreased from 5 to 15 min compared with that at baseline. Stroke work decreased from 5 to 15 min compared with that of the control group; it decreased from 5 to 15 min compared with that at baseline. Conclusion: Our results showed that 3.0 U/mL concentration of vasopressin resulted in increased blood pressure, decreased stroke volume and stoke work, decreased preload and increased afterload, without any effect on myocardial contractility.
