Abstract

A functional skin-flap model of angiogenesis in the mouse was utilized to investigate ischaemic flap survival/angiogenesis whilst under pharmacological or genetic inhibition of nitric oxide synthase (NOS). In this model, the epigastric artery was cauterized. Following a five-day angiogenic period an abdominal skin-flap supplied by the pre-existing epigastric artery was raised and resutured. After a further six days the outcome was determined by measuring the area of living skin-flap that was sustained by new vessel growth around the cauterized artery. Both pharmacological [ S-methyl-isothiourea (SMT) given via i.p. injection for the five-day angiogenic period] and genetic inhibition of NOS 2..
