摘要:

已有研究显示,依诺肝素通过其抗凝作用可减轻脑损伤,为了解依诺肝素对冷冻性脑损伤的影响,实验在建立BALB/c小鼠冷冻性脑损伤模型后20min,随机给予腹腔注射3 ,10 mg/kg依诺肝素或等渗盐水干预。给药后24h发现,10 mg/kg依诺肝素可明显缩小冷冻性脑损伤小鼠大脑皮质的脑梗死体积、减少大脑皮质细胞凋亡,明显提高血清总抗氧化物水平;而3 mg/kg依诺肝素则上述作用不明显。由此说明,依诺肝素对冷冻性脑损伤有神经保护作用,且该作用呈剂量依赖。

Abstract:

Recent evidence exists that enoxaparin can reduce brain injury because of its anticoagulant activity. To investigate the potential therapeutic effect of enoxaparin on cold-induced traumatic brain injury, at 20 minutes after modeling, male BALB/c mouse models of cold-induced traumatic brain injury were intraperitoneally
administered 3 and 10 mg/kg enoxaparin or isotonic saline solution. Twenty-four hours later, enoxaparin at 10 mg/kg greatly reduced infarct volume, decreased cell apoptosis in the cortex and obviously increased serum level of total antioxidant status. By contrast, administration of enoxaparin at 3 mg/kg did not lead to these changes. These findings suggest that enoxaparin exhibits neuroprotective effect on cold-induced traumatic brain injury in a dose-dependent manner.
