AB - Objectives :
Eucommiae cortex is reported that it helps bone and skeletal muscle stronger. In case of bone, many report is presented, but reports related to skeletal muscle are rarely existed. So in order to investigate effects of Eucommiae cortex on the skeletal muscle atrophy following stroke, cerebral infarct was induced by the middle cerebral artery occlusion (MCAO) in the rats.
Methods :
In order to induce MCAO rats, nylon suture was advanced and then blocked middle cerebral artery(MCA). Water extract of Eucommiae cortex was treated for 15 days, once a day orally, after the MCAO. Effects were evaluated with muscle weights, muscle fiber type composition, cross-sectioned area of muscle fibers in soleus and gastrocnemius of the unaffected and affected hind limbs. And MyoD protein expression in gastrocnemius was demonstrated with immunohistochemistry and western blotting.
Results :
In the affected hind limb of the MCAO rats, muscle weight loss of gastrocnemius and tibialis anterior muscles were attenuated by Eucommiae cortex treatment. In soleus muscle of the affected hind limb of the MCAO rats, increase of type-I fibers and decrease of type-II fibers were induced by Eucommiae cortex treatment. In soleus muscle of the affected hind limb of the MCAO rats, decrease of cross-sectioned areas of type-I fibers was attenuated by Eucommiae cortex treatment. In gastrocnemius muscle of the affected hind limb of the MCAO rats, increase of type-I fibers and decrease of type-II fibers were induced by Eucommiae cortex treatment. In gastrocnemius muscle of the affected hind limb of the MCAO rats, decreases of cross-sectioned areas of type-I and type-II fibers were attenuated by Eucommiae cortex treatment. In gastrocnemius muscle of the affected hind limb of the MCAO rats, MyoD positive cells were increased by Eucommiae cortex treatment. In gastrocnemius muscles both of the affected and unaffected hind limb of the MCAO rats, MyoD expressions were increased by Eucommiae cortex treatment.
Conclusions :
These results suggest that Eucommiae cortex has a protective effect against muscle atrophy, through the inhibition of the muscle cell apoptosis, following the central nervous system demage.
