ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of Ligusticum and its two components (Sodium Ferulate and Ligustrazine as main efficacy components in Ligusticum for invigorating blood circulation) on muscle atrophy in a hind limb unloaded rat model.</p><p><b>METHODS</b>The tail-suspended rats were subjected to a 14-days disuse, immunohistochemistry and hemorheology were used to study the effects of medicines on soleus muscle.</p><p><b>RESULTS</b>Compared with HLU+ W (1) The CSA of soleus type I fibers in HLU + SfH and HLU+ TmpH increased by 37.3% and 39.4% respectively (P < 0.05). (2) Expression level of MHC II were inhibited in all treatment groups (P < 0.01). (3) Expression of MHC II in nuclear bag 2 fiber were altered from positive to negative. (4) The blood viscosity in low shear rates decreased obviously (P < 0.01), even near to control.</p><p><b>CONCLUSION</b>Ligusticum and its two main efficacy components (Sodium Ferulate and Ligustrazine) can prevent soleus atrophy induced by disuse, and Sodium Ferulate and Ligustrazine in high dose showed most efficacy.</p>
