Abstract:
Objective To study the effect of mild hypothermia on aquaporin 4 (AQP4) expressions and cerebral edema after intracerebral hemorrhage and the mechanisms of mild hypothermia on hemorrhagic brain edema. Methods The model of intracerebral hemorrhage (ICH) was established by infusing collagenase into right globus pallidus of the rat. The temperature was regulated by ice cubes and daylight lamp, which was modulated to an appropriate distance to the animals. Immunohistochemistry staining was used to detect the cerebral AQP4 expressions. Dynamic change of brain edema was observed through wet-dry weighing method. Results The brain water content (BWC) of injured side and level of AQP4 expression in perihematom tissue in ICH rats were obviously higher than those of the sham group (all P
