Enhancement of cerebrovascular effect of CO2 by hypoxia.

abstract：BACKGROUND AND PURPOSE:Silent brain infarction (SBI) is often found with white matter hyperintensity. A recent genetic study on elderly twins indicated that the susceptibility to white matter hyperintensity was largely determined by genetic factors, implying the existence of genetic susceptibility for SBI as well. We t...
