Objectives : This study was performed to evaluate effects of Yangsim-tang extract (YST) on hemodynamics (regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) ) in normal rats, and effects of cyclooxygenase and guanylate cyclase under YST. Methods : Laser-Doppler flowmetry (LDF) measured changes of rCBF, and a data acquisition system assembled with MacLab and Macintosh measured changes of MABP. Results : YST significantly increased rCBF, but did not change MABP. Pretreatment with indomethacin significantly inhibited rCBF increased by YST, but pretreatment with methylene blue did not significantly inhibit rCBF increased by YST. Conclusions : YST increases rCBF, and the action of this response is mediated by cyclooxygenase.

Brady-arrhythmia is defined as an arrhythmia in which the heart rate slows to less than 60 beats per minute. Brady-arrhythmia reduces cardiac output and causes changes in blood flow. As a result, dizziness occurs because not only ischemia occurs in the central nervous system, but also blood flow in major organs decreases. The insertion of an artificial pacemaker is known as almost the only treatment alternative for patients with brady-arrhythmia with symptoms. This study reports a case of 85 year old male diagnosed with brady-arrhythmia complaining presyncope type of dizziness. The patient underwent complex Korean medicine treatments by herbal medicine, acupuncture and moxibustion. The daily average value of pulse rate, K-DHI score, NRS score and the patient's subjective expression of symptoms were used as evaluation tools. This study suggested a significant improvement in symptoms through complex Korean medicine treatments without the use of anti-arrhythmic drugs or insertion of an artificial pacemaker in the patient with brady-arrhythmia complaining dizziness.
