Patent foramen ovale in cryptogenic stroke: incidental or pathogenic?

abstract：BACKGROUND AND PURPOSE:We examined the possibility that activation of the human brain renin-angiotensin system is involved in enhancement of ischemic brain damage using chimeric transgenic mice with human renin (hRN) and human angiotensinogen (hANG) genes. METHODS:Chimeric (hRN/hANG-Tg) mice were generated by mating o...
