【Abstract】 Microcirculatory flow of nail bed,blood-2,3 DPG and deformability of RBC in 40 cases with different degree 9f CHD were studied and found that:（1）velocity of flow was inversely proportional to vessels involved（P<0.01）;（2）Salvia miltiorrhiza（SM）increased velocity of flow,with its action delayed in proportion to vessels involved;（3）2;3 DPG of RBC and blood were increased after SM administration;（4）deformability and filtration of RBC were increased after SM administration（P< 0.01）.In 12 rabbits,20% dextrane was given to form acute microcirculatory disturbance model. Mesenteric microcirculatory flow,blood 2,3 DPG,and deformability and filtration time of RBC were studied before and after dextrane and SM administration.It was found that:（1）velocity of blood flow was slowed after dextrane and increased after SM（P<0.01）;（2）blood and RBC 2,3 DPG were decreased after dextrane and increased by SM（P<0.01）;（3）deformability and filtration time were decreased after dextrane and increased after SM（P<0.01）.The blood gases and 2,3 DPG of 12 rats were studied after putting into an airtight bottle containing 12～15% O₂ for 30 min.to form acute hypoxia model.It was found that PO₂ and 2,3 DPG were lowered in control and only slightly lowered in SM group（P<0.01）.It was concluded that there was microcirculatory and 2,3 DPG disturbance in patients with CHD whichcould be improved by SM.The increase of microcirculatory flow after SM was related to increase of 2.3 DPG of RBC and deformability of it.which maintained a relative high PO₂ of blood after an hypoxic condition.更多还原
