Abstract
  1. The potential of AE0047, a novel calcium antagonist, to remedy brain damage of stroke-prone spontaneously hypertensive rats (SHRSPs) with signs of stroke was compared with those of nicardipine and hydralazine. 2. AE0047 (1 and 3 mg/kg/day) given daily to diseased SHRSPs prevented mortality and improved neurological symptoms. Histological examination also supported the effectiveness of AE0047 against the progression of the disease. 3. Nicardipine (10 mg/kg/day) and hydralazine (10 mg/kg/day) were less effective than AE0047 in a dose equal to or more than the hypotensive dose, respectively. 4. AE0047 may be beneficial for treating the acute stage of stroke in humans by virtue of its long-lasting hypotensive action and undefined direct actions on the cerebral vasculature.
摘要
  1. 将新型钙拮抗剂AE0047与尼卡地平及肼屈嗪相比,评估其对出现中风症状的易中风自发性高血压大鼠(SHRSPs)脑损伤的治疗潜力。2. 每天给患病的SHRSPs服用AE0047(1毫克/千克/天和3毫克/千克/天)可预防死亡并改善神经症状。组织学检查也证实了AE0047对疾病进展的疗效。3. 尼卡地平(10毫克/千克/天)和肼屈嗪(10毫克/千克/天)在等于或高于降压剂量时,疗效均不如AE0047。4. AE0047因其持久的降压作用以及对脑血管系统的未知直接作用,可能对治疗人类中风急性期有益。
