Wang Cheong-Im(1768-1831) in the Ching dynasty conducted the therapy of blood statis syndrome using the methods for promoting blood circulation and removing blood statis in accordance with the description in the book Uirimgaechak(醫林改錯). Thus, this study examined his methods for promoting blood circulation and removing blood statis, therapy of blood statis syndrome and mechanism of function. Since the blood statis symptoms varied on the parts where the blood statis were occurred, the therapy for promoting blood circulation and removing blood statis applied different treatments and drugs depending on the symptoms. The therapy also valued much of qi and blood. Qi is important to the human body so that the therapy replenished qi and simultaneously promoted the blood circulation as mainly focusing on the regulation of the qi flow. Moreover, the therapy adjusted the level of removing blood circulation and rate of replenishing qi. The degree of prescription and drug was differentiated in treating a variety of blood statis because of the difference in the seriousness and characteristics of blood circulation, amount and application of drug and combination of drugs. The therapy was careful about the regulation of qi for the replenishment of qi and the nurishment of blood for the promotion of blood circulation. If the blood circulation was blocked, the blood statis was formed. Accordingly, the phlegm and the blood statis were closely related. Then, the phlegm and blood statis were simultaneously treated. The therapy divided the properties of blood statis into the stagnant excess syndrome, the stagnant deficiency syndrome, the stagnant cold syndrome and the stagnant heat syndrome and treated the patients suitable for each symptom. The function of mechanism in the treatment using the methods for promoting blood circulation and removing blood statis was divided into the stagnation of blood and interruption in blood circulation. The therapy laid stress on promoting blood circulation and removing blood circulation. With such emphasis, the therapy facilitated the circulation in the bloood vessel, prevented the coagulation of blood, removed the blood statis and promoted the metabolism. Then, the physiological function and pathological change internal organs were improved. Furthermore, the therapy strengtened the heart and promoted the blood circulation by improving the systemic blood circulation. Moreover, the therapy facilitated the micro-circulation by adjusting the balance of body.

The concept of Blood Stasis had been cognized merely as a sign in disorder of blood circulation since "Huangjenaegyeong(黃帝內經)" until "Sanhanron(傷寒論)" and "Geumgweyoryak(金匱要略)" started to describe, explain and apply independent symptom of blood stasis to practice. In this article, establishing the estimate feature of symptom of blood stasis in "Geumgweyoryak(金匱要略)" is the main subject, in sequence the pathological mechanism and targets of prescriptions suggested in "Geumgweyoryak(金匱要略)" are analyzed and restructured. In conclusion, the symptom of blood stasis in "Geumgweyoryak(金匱要略)" is caused not only from disorder of blood circulation but also from metal depression, therefore there are always appearances of excessive and deficient status simultaneously, in the process of symptom. The research on concept of blood stasis from the literatures in early ages will be the basis of future studies about disease of circulation in Korean Traditional Medicine.

Purpose : The purpose of this study is to have examined the influence on the blood circulation by comparing the differences between stimulating the sympathetic ganglion and the muscle group among the stimulation variables in interferential current stimulation and to have found out the most effective stimulating mode for the improvement the peripheral blood circulation in the interferential current stimulation. Method : The subjects of the study is the men and women in the twenties, who are in great condition and have no pathological report for the blood circulation influence. The intensity of the inferential current stimulation is the medium degree, 100 bps constant current, which is the comfort and overt degree to confirm the muscle contraction. The areas stimulated by the interferential current stimulation are the stellate ganglion area in the seventh cervical vertebrae and the forearm muscle area. The stimulating time is twenty minutes long. After stimulating the two areas, the change of the blood circulation has been measured. Results : Both stimulating the sympathetic ganglion and stimulating the muscle, before and after interferential current stimulation, we have seen that the amount of blood circulation was increased significantly and statistically in both two groups(p<.01) and that the amount of blood circulation was increased significantly and statistically in the case of stimulating the sympathetic ganglion(p<.01). Conclusion : The conclusion we received that inferential current stimulation had the clear influence on increasing the peripheral blood circulation. And stimulating the sympathetic ganglion area is more effective than stimulating muscle area directly.

Blood circulation is one of the most important life support functions of our body. It is essential to maintain healthy blood circulation as problems with blood circulation can lead to numerous diseases and serious complications. This study developed women's leggings with gradual compression and soft surface heating functions to improve blood circulation, and evaluated their performance and wearability. A silicon print pattern was developed to provide gradual compression, and a flexible heating surface coated with MWCNT (multi-walled carbon nanotube) conductive ink was fabricated for comfort and thermal effect. For the design, incision lines and materials were applied in consideration of aesthetic aspects, and design lines and colors were altered using a 3D program. The developed leggings showed that blood circulation can be improved when gradual compression and heating functions are simultaneously applied. Results were confirmed through measurements of clothing pressure, blood flow, and surface temperature. In the subjective wearability evaluation, it was confirmed that wearers felt gradual pressure, and they showed high satisfaction with wearability and design.

The concept of blood circulation is so complex, dynamic and abstract that students have difficulty in understanding it and students' preconceptions hardly change into scientific concepts even after the lessons. The purpose of this study is to examine middle school, high school, and undergraduate students' understanding of blood circulation and to find the reason why the lack of deep understanding is displayed in students' explanations for the blood circulation. The study consists of three parts. First, the test was designed to investigate students' ideas for blood circulation as components of the structure, the function, the behavior and the mechanism. Second, the test was applied to 7th, 10th and 13th graders to investigate the students' understanding of blood circulation and categorize the types of students' blood circulation model according to their academic level. Finally, the concepts the students had little understanding of were analyzed to decide which ontological category they fell into and further to inquire the characteristics of each concept. The results showed that many students comprehend the structure and the function of blood circulation components well, and there was no significant difference in students' understanding according to the academic level. In contrast, understanding the behavior and the mechanism of circulatory components has remarkably improved in high school students and undergraduates majoring in science and engineering. Also, students' blood circulation models were classified into seven different types. High school students and undergraduates majoring in science and engineering demonstrated a significantly higher percentage on the type of double-loop-branch compared to other academic levels. In addition, it was found that the lack of deep understanding was caused by students' misconceiving the 'equilibrium' category as 'event' category.

Objectives : We investigated the correlation of the skin color to blood circulation on the face of Korean female by noninvasive-skin measuring devices. Methods : Korean female(37.47${\pm}$3.66 years, n=36) aged 30-45 years were participated in this study. We measured the skin color of the face with Spectrophotometer CM2600d (Minolta, Japan) and the skin blood flow with Laser Doppler Imaging-Periscan PIM II (Perimed AB, Sweden). The skin color and blood circulation of three groups (30-35 years, 36-40 years, 41-45 years) divided on age were analyzed by paired-t test and regression analysis. Results : The L* values of the skin were decreased and the a* values were increased significantly with age. This means that the more age increase, the more the skin is dark and red. But the skin blood flow was not significantly different with age and skin color. Conclusions : In the oriental medicine, It was reported that the face of the female over 35 years is changed gradually haggard and the blood circulation is decreased. In our study, the blood circulation was not changed and the skin color was dark and red with increasing the age. We think this symptom resulted from the better nutrition than the past, the change of the blood-quality and this changes were too sensitive to be measured by Laser Doppler Imaging system.

The present study has been undertaken to investigate the effect of the extract of Cirsium japonicum var. ussuriense leaves (CLE) on blood circulation in a rat model of topical ferric chloride ($FeCl_3$)-induced carotid artery damage. $FeCl_3$ treatment seriously damaged the carotid artery such as the walls of the artery, blood flow and inflammation. However, CLE administration has ameliorated blood circulation and suppressed vessel inflammation. CLE administration also has ameliorated the $FeCl_3$-induced artery tissue damage. Furthermore, CLE significantly suppressed the expression of adhesion molecules. These results suggest that CLE ameliorate blood circulation through suppress inflammatory mediator and adhesion molecule production.

The ECMO system, including umbilical cord and membrane type oxygenator was connected with extracorporeal circulation unit, was applied to the fetus growth model of goat. The maximum survival time of goat fetus was 48 hours. Average blood rate for the extracorporeal circulation was $223{\pm}15.2 ml/min.$ The survival time of fetus was deeply related to body temperature, blood circulation and water temperature, anesthetized time, and fetus weights. Extern variables that are composed of anesthetized time, fetus weights, change of hemoglobin, circuit pressure, related to the survival time for fetus corrected the problem of previous ECMO model that is controlled by roller pump. It is directly delivered to heart on load. Applying the results from new ECMO model, further research will provide to the system of ECMO for human.
