卒中起始后的最初几个小时作为诊断步骤的 CT其价值有限,须另觅其他灵敏预后标志。有报道在腔隙性梗塞和短暂的轻度机能障碍,患者脑脊液(CSF)乳酸脱氢酶(LDH)浓度增高而其他酶浓度没有上升,但这现象仅见于发病后期(梗塞后48～90小时),此时 LDH 达到峰值水平,由于此酶在脑内浓度高于谷草转氨酶,也比肌酸激酶耐热,提示可作灵敏标志,应用于轻度和中度卒中患者。为此,本文观察在卒中和矩暂性缺血发作(TIA)开始阶段时,CSF 的
The first few hours after the onset of stroke are of limited value as diagnostic procedures for CT, and other sensitive prognostic markers must be found. It has been reported that in patients with lacunar infarction and transient mild dysfunction, the concentration of lactate dehydrogenase (LDH) in the cerebrospinal fluid (CSF) is elevated and the concentration of other enzymes is not increased, but this phenomenon is seen only in the late onset (48 to 90 hours after infarction ), LDH peaked at this time. As this enzyme is more intragranular than aspartate aminotransferase it is also more thermostable than creatine kinase, suggesting a sensitive marker for mild to moderate stroke. To this end, this article observed in the beginning of stroke and transient ischemic attack (TIA), CSF
