补气活血类组方对实验性肺气虚证大鼠血液流变学的影响

Effect on the experimental syndrome of insufficienoy of Lung Qi of rats by 3 kinds prescription

通过动物实验证明，补气活血方、补气方和活血方均能降低实验性肺气虚证大鼠红细胞聚集性、血液粘度和红细胞压积。前两方除上述作用外，还能减低红细胞刚性，增强红细胞变形能力。但在抑制该模型高聚、高粘状态作用上，补气活血方显著优于补气方和活血方。因此，可以认定对肺气虚证的血瘀状态，只有补益肺气，辅以活血化瘀，才能最有效地促进气血运行，改善组织器官的供血供氧。进一步证实了气对血的推动作用。

The formulae of invigorating qi and promoting blood circulation, invigorating qi and promoting blood circulation has been proved by animal experiment to reduce experimental syndrome of insufficiency of lung qi, rat's erythrocyte clustering, blood viscosity and packed cell volume. Besides the above function, the first two formulae can also reduce the erythrocyte rigidity and increase the erythrocyte deformation ability. However, the formula of invigorating qi and promoting blood circulation is superior to the other two formulae in inhibiting the condition of high clustering and high viscosity of the animal model. Therefore, it can be regarded that the combination of replenishing or restoring the lung qi and promoting od circulation by removing blood stasis can most effection promote the qi blood circulation and improve the blood suplly and sygen supply of tissue or organ, that is, Improve the state has tasis caused by syndrome of insufficiency of lung qi, which confirmed the scientific nature of qi's promoting and biochemical function on blood in a further degree.
