abstract = {In a previous study from our group, argon has shown to
significantly attenuate brain injury, reduce brain
inflammation and enhance M2 microglia/macrophage
polarization until 7 days after ischemic stroke. However,
the long-term effects of argon have not been reported thus
far. In the present study, we analyzed the underlying
neuroprotective effects and potential mechanisms of argon,
up to 30 days after ischemic stroke. Argon administration
with a 3 h delay after stroke onset and 1 h after
reperfusion demonstrated long-term neuroprotective effect by
preserving the neurons at the ischemic boundary zone 30 days
after stroke. Furthermore, the excessive
microglia/macrophage activation in rat brain was reduced by
argon treatment 30 days after ischemic insult. However,
long-lasting neurological improvement was not detectable.
More sensorimotor functional measures, age- and
disease-related models, as well as further histological and
molecular biological analyses will be needed to extend the
understanding of argon’s neuroprotective effects and
mechanism of action after ischemic stroke.},
