The effect of methylprednisolone (MP) on neurologic recovery and spinal cord blood flow (SCBF) was investigated up to 4 days after a spinal cord compression injury in rats. The injury was produced at midthoracic level by applying a load of 35 g on a 2.2 × 5.0 mm compression plate for 5 min, which resulted in transient paraparesis. MP was given as a bolus dose of 30 mg/kg i.v. 60 min after injury (n = 20) and controls were given saline (n = 10). The motor performance was assessed daily as the capacity angle on the inclined plane and SCBF was measured by 14C‐iodoantipyrine autoradiography on Days 1 or 4. On Day 1 the capacity angle was reduced from about 63° preoperatively to 33 ± 2° (mean ± SEM) in the control group and to 50 ± 1° in the group treated with MP (p < 0.05). Thereafter there was a slight improvement in both groups, but the difference persisted throughout the observation period. On Day 4 both gray and white matter SCBF was better preserved in MP‐treated animals than in the control group (59 ± 4 versus 49 ± 3 ml/min/100 g tissue for gray matter and 13.6 ± 0.6 versus 10.7 ± 0.8 ml/min/100 g tissue for white matter). Post‐traumatic treatment with MP, thus, improved both the neurologic recovery during the first 4 days and SCBF as measured on Day 4. It is speculated that the effect of MP is at least partly exerted on the vascular bed.
