Therapeutic effects of artificial musk on acute ischemic stroke and subarachnoid hemorrhage in rats

The rat models of focal cerebral ischemic reperfusion and subarachnoid hemorrhage were used to evaluate the therapeutic effects of artificial musk to provide support for its clinical application. All animal experiments were performed following the regulations of the Animal Ethics Committee of Peking Union Medical College. The results showed that oral administration of artificial musk had significant protective effects on acute ischemic and hemorrhagic stroke. In the dose range of 10-200 mg·kg^-1, the mortality, neurobehavioral and cerebral infarction volume of rats in model group indicated a clear dose dependent relationship. The effective dose of artificial musk is 10 mg·kg^-1 in ischemic stroke and 200 mg·kg^-1 in hemorrhagic stroke. These findings suggest that the treatments of artificial musk in ischemic stroke and in hemorrhagic stroke are different, and such differences should be noted for its clinical use.
