[Advances in research on neuroprotective effects of inert gas].

Inert gas is a group of rare gases with very low activity, their application in medical field has increasingly drawn attentions. It is known that inert gases helium, xenon and argon have protective effects on nervous system and the mechanisms are related to eradicating free radicals, anti-inflammation, suppressing apoptosis, influencing ion channels and so on. Further study on the neuroprotective effect of inert gas will shed light on a new approach to treat neurological diseases.
