Cx43 siRNA and PKC inhibitors alleviated the changes in proportion and severity of microarterioles on SAH animals. a Examples of pearl string-like microarteriolar spasm (white arrow) in the cerebral microcirculation on 7 days after SAH. By investigating the morphology of microarteriolar spasm under intravital microscopy two sides of microarteriolar spasm represent the normal value of diameter (bar = 50 μm). b The proportion of spastic vessels quantified as percentage of all vessel segments among the ipsilateral MCA at 7 days after SAH. c The severity of vasospasm represented as change in diameter at 7 days after SAH (n = 8, **P<0.01 vs. sham group. #P<0.05, ##P<0.01 vs. SAH-only group).
