ABSTRACT |
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. |
