Outline of Final Research Achievements |
This study aimed to clarify the bioprotective mechanism of goshajinkigan (GJG), a kampo prescript, in comparison with keishibukuryogan (KBG), a typical kampo anti-oketsu prescription. The analysis made by live-imagings of the murine and rat animal models. The main pharmacological target of GJG was the capillary vessels, while that of KBG was the arterioles. GJG enhanced the blood flow through the increase of capillary blood flow velocity and this effect was nitric oxide (NO) independent. In contrast, KBG induced vasodilation through NO dependent mechanism.
