目的　观察腰痛胶囊对腰肌损伤后组织病理、局部血流量的影响。方法　利用机械打击制造家兔腰肌损伤模型 ,观察灌服高中低剂量的腰痛舒胶囊对组织病理和局部血流量的影响。结果　造模后家兔受损腰肌局部血流量较正常组织明显下降。腰痛舒胶囊能明显增加被损腰肌的局部血流量 ,以高中剂量最为显著。组织形态学也证实能促进受损腰肌的修复。结论　腰痛舒胶囊能明显增加腰肌损伤后的局部血流量。促进腰肌组织的修复。 Objective To observe the effect of Yaotong Capsule on histopathology and local blood flow after lumbar muscle injury. Methods The rabbit lumbar muscle injury model was mechanically attacked to observe the effects of high-medium low-dose Lutongshu Capsule on histopathology and local blood flow. Results The local blood flow of injured lumbar muscle in rabbits after modeling was significantly lower than that in normal tissues. Lutongshu Capsule can significantly increase the local blood flow of the injured psoas, which is most significant at high school. Histomorphology also confirmed that it can promote the repair of injured lumbar muscles. Conclusion Yaotongshu capsule can significantly increase the local blood flow after lumbar muscle injury. Promote the repair of psoas muscle tissue.
