Ultrasound recordings of the carotid flow velocities in apoE^−/− (a) and C57BL/6J (b) groups. A1: baseline flow velocity in apoE^−/− group. A2: flow velocity in the carotid 7 days after carotid surgery in apoE^−/− group. A3: flow velocity in the carotid 14 days after carotid surgery in apoE^−/− group. A4: flow velocity in the carotid 28 days after carotid surgery in apoE^−/− group. B1: baseline flow velocity in C57BL/6J group. B2: flow velocity in the carotid 7 days after carotid surgery in C57BL/6J group. B3: flow velocity in the carotid 14 days after carotid surgery in C57BL/6J group. B4: flow velocity in the carotid 28 days after carotid surgery in C57BL/6J group. The blood flow velocity of apoE^−/− (c) and C57BL/6J (d) groups were calculated from pre-surgery tracings and 7, 14 and 28 days after surgery. Data are mean ± SD. There was a highly significant of velocity at baseline. *P < 0.05, n = 40, compared to baseline
