Objectives: Sahyangsohapwon (SS) is a herbal medication that has been widely used with circulatory and neural diseases. This study was conducted to assess the effect of SS on the autonomic nervous system by using heart rate variability measurement. Methods: The eligible subjects were enrolled from the healthy male group of ages 20 to 35 years. They were divided into two groups, the SS group (n=26) and the control (n=24). We monitored the ECG of subjects from the time period 14:00 to 18:00. In the SS group, subjects were administered with a dose of SS at the time 15:00, whereas the control group had none. For each hour HRV measurement was monitored every 15 minutes for 512 seconds from the time period 14:00 to 18:00. The mean value, which was calculated using the 4 values during each hour (i.e. 14:00, 14:15, 14:30, 14:45), was used as the representative value for each individual hour. For the measurement values, RR-interval and SDNN (standard deviation of the NN intervals) were used as time domain analysis, and HF (high frequency), LF (low frequency), and LF/HF ratio were used as frequency domain analysis. Results: The LF value showed an increase after one hour of SS administration and showed gradual diminution for each and every hour. The repeated measures of ANOVA for the comparison of the LF value between the SS group and the control group showed significant differences. While, RR interval, SDNN, HF, and LF/HF ratio values showed no significant differences between the two groups. Conclusions: We suggest that the SS might be useful for stabilizing autonomic nervous system by inhibiting sympathetic nerve activation in healthy people.

Cerebrovascular and cardiovascular diseases (CVDs) are a major cause of deaths among workers as well as in general population in Korea. Occupational stress like long working hours or overwork can cause sudden unexpected death in a worker who had been suffering from an aggravated preexisting condition such as hypertensive or arteriosclerotic diseases, The Korean government has compensated the cases of cerebrovascular disease and cardiovascular disease due to overwork, but neither a resonable definition of overwork nor detailed evaluation guideline has been officially provided to verify overwork, so that the prevention of, as well as compensation for workers' occupational stress-related cardiovascular attacks, cannot be carried out efficiently. A thorough understanding of the etiopathology of WR-CVDs can be very helpful in developing a prevention strategy.

In our country, cardiovascular disease (CVD) and Coronary heart diseases (CHD) are the leading causes of death. It is well known that CHD is multifactorial, involving environmental factors such as diet, level of exercise and cigarette smoking, and inherited factors. According to the statistical data in 2003, the cause of death with the highest mortality was including hypertension, ischemic heart disease and atherosclerosis, which accounted for $24.7\%$ of total mortality. In spite of, there have been few study reports on the change of biochemical markers and mechanisms concerned. The development of biochemical markers is required for an early diagnosis and treatment of cardiovascular diseases that are related with dietary habits of Korean people enjoying mixtures of traditional dietary style and westernized food-styles. Therefore, the most efficient cost-saving biochemical marker was established in this study, through analysis of biochemical markers related with dietary habits which are susceptibly being changed in association to cardiovascular diseases from the pre-disease phase, and through reanalysis and assessment of early diagnosis of and preventive effects of diagnosis of cardiovascular diseases by demographical character including sex, age, and socioeconomic level with use of biochemical markers that are identified and selected among the parameters in consideration of the effectiveness and appropriateness of early diagnosis of diseases. The appropriateness of biochemical markers was reviewed by professionals (medical, pharmaceutical area and food/ nutrition area) and CRP(C-Reactive Protein) and was identified to be possible in Korea. It is thought that these biochemical markers may be used as the basic data for early diagnosis and prevention of cardiovascular diseases (CVD) which may be used for Korean people.

Objective : Stroke patients tend to take antibiotics due to infection resulting from complication. One of many side effects from using antibiotics is diarrhea, which infact causes anaerobic organism dysfunction resulting Pseudo-Membranous Colitis (P.M.C). To treat P.M.C, antibiotics and antibacterial agents are usually used. But they may cause other side effects, therefore extreme caution must be taken. Methods : We treated an antibiotic induced P.M.C patient who diagnosed by sigmoid scopy with only Yijoong-tang (Lizhong-tang) without antibiotics and observed patients stool aspects. Results and Conclusion : Patiensts symptom was improved after 7days, and we can see the improvement by follow-up sigmoid scopy. This case may give us a possibility of that oriental medical treatments as complementary and alternative medicine to standard antibiotic treatment.

Objectives: We examined the association of hearing with cardio-metabolic diseases, dyslipidemia, hypertension and diabetes mellitus according to the personal and occupational characteristics of workers exposed to noise. Methods: The subjects of the study were 237,028 workers who underwent 2, 3, and 4 kHz airway pure tone audiometry in 2015 and who underwent clinical tests to diagnose cardiovascular-metabolic diseases. Cardiovascular-metabolic diseases were defined using reference values for respective items including blood pressure (systolic/diastolic), fasting blood glucose, cholesterol, and triglycerides. The airway pure tone hearing threshold of 2, 3, and 4 kHz, the average threshold of 2-3-4 kHz, and the hearing loss by the average threshold of the primary examination were distinguished. Results: Workers with cardiovascular-metabolic disease had significantly higher average hearing thresholds and higher rates of hearing loss. Logistic regression analysis, which adjusted for demographic variables of gender and age and occupational variables such as workplace size, industry, and type of work, and cardiovascular-metabolic disease as independent variables, showed that the odds ratio of hypertension to hearing loss in the mid-frequency was 1.239 (95% confidence interval: 1.118-1.374). For hypertension was 1.159 (1.107-1.214) and for diabetes it was 1.166 (1.104-1.230) for hearing loss in the high-frequency. Hearing loss measured by mean hearing was 1.178 (1.105-1.256) for hypertension and 1.181 (1.097-1.271) for diabetes. Conclusions: Cardiovascular-metabolic diseases in noise-exposed workers are associated with an increased risk of hearing loss and should be accompanied by bio-monitoring of cardiovascular-metabolic diseases in addition to auditory surveillance.

Objectives : Metabolic syndrome (MetS) is associated with increasing risk of cardiovascular morbidity and mortality but the risk of stroke associated with the MetS is less well established. The objective of this study was to evaluate the prevalence of MetS in stroke patients. Methods : We analyzed the data of 806 patients with acute ischemic stroke from Hanbang Stroke Registry supported by the Ministry of Science and Technology of Korea. Subjects' enrollment was done in the oriental medical hospitals of 4 universities located in the metropolitan region from April 2007 to August 2008. We analyzed all registered data and evaluated the prevalence of MetS and specific components of MetS. Results : The prevalence of MetS in stroke patients according to American Heart Association/National Heart Lung and Blood Institute (AHA/NHLBI) criteria was 59.6%. The prevalence according to the International Diabetes Federation (IDF) criteria was 41.6%. The prevalence of female patients was higher than that of male patients (71.8% vs 51% by AHA/NHLBI criteria; 61.7% vs 27.7% by IDF criteria). The prevalence of central obesity, low HDL cholesterol and hypertension was higher in female patients. There was no significant relationship between MetS and stroke subtype. Conclusions : This work gives us the basic data on the association between MetS and risk of stroke. There should be the prospective cohort studies to evaluate MetS and the risk of stroke.

Chronic diseases such as cancer, cardiovascular diseases, are the leading cause of death and disability in Korea since 1970 due to lifestyle change introduced by urbanization & industrialization. The type of cancer and cardiovascular diseases changes as lifestyle becomes westernized. These diseases account for 4 of every 10 deaths and affect the quality of lift of Koreans. Although chronic diseases are among the most common and costly healthy problems, they are also preventable. Adopting healthy behaviors such as quitting smoking, being physically active, eating right with moderate alcohol drinking, and maintaining healthy weight can prevent or control the effect of these diseases.

Objective : Interaction of warfarin with herbal medicines still remains controversial. The aim of this study was to examine the effect of herbal medicines which contain ginseng on PT INR in patients being treated with warfarin. Method : We studied patients who take herbal medicines which contain ginseng with warfarin during their hospitalization. We retrospectively investigated the effect of herbal medicines which contain ginseng. 10 patients were assigned to receive one of the following adjuncts: Group A (n=4) that received Bojungikkitang-gagam, Group B (n=2) that received Ukgunjatang-gagam, and Group C (n=4) that received Shihogyeji-tang, Gamiondam-tang, Gwininaanshim-tang, and Saengpe-san together. We then investigated changes of PT INR in each group. Result : In group A, there were diminutions of PT INR in 3 cases, and increment in 1 case. In group B, there were increments of PT INR in both cases. In group C, there were increments of PT INR in 3 cases and there was no big change in 1 case. Conclusion : In this study, we found that the interaction of combined herbal medicine is very complicated. So, we must study further more study about interactions of combined herbal medicine on PT INR.

Ischemic preconditioning (IPC) is known to protect the heart against ischemia/reperfusion (IR)-induced injuries, and regional differences in the mitochondrial antioxidant state during IR or IPC may promote the death or survival of viable and infarcted cardiac tissues under oxidative stress. To date, however, the interplay between the mitochondrial antioxidant enzyme system and the level of reactive oxygen species (ROS) in the body has not yet been resolved. In the present study, we examined the effects of IR- and IPC-induced oxidative stresses on mitochondrial function in viable and infarcted cardiac tissues. Our results showed that the mitochondria from viable areas in the IR-induced group were swollen and fused, whereas those in the infarcted area were heavily damaged. IPC protected the mitochondria, thus reducing cardiac injury. We also found that the activity of the mitochondrial antioxidant enzyme system, which includes manganese superoxide dismutase (Mn-SOD), was enhanced in the viable areas compared to the infarcted areas in proportion with decreasing levels of ROS and mitochondrial DNA (mtDNA) damage. These changes were also present between the IPC and IR groups. Regional differences in Mn-SOD expression were shown to be related to a reduction in mtDNA damage as well as to the release of mitochondrial cytochrome c (Cyt c). To the best of our knowledge, this might be the first study to explore the regional mitochondrial changes during IPC. The present findings are expected to help elucidate the molecular mechanism involved in IPC and helpful in the development of new clinical strategies against ischemic heart disease.
