ACZ

Objective To study the value of MR perfusion-weighted imaging acetazolamide ( ACZ ) in evaluating the cerebrovascular capacity.

目的探讨乙酰唑胺 ( ACZ ) 负荷MR灌注成像对评估脑血管储备功能的价值.

Type C 1: the rest rCBF was decreased, and remained unchanged after ACZ;

C1型：静息时rCBF减低，负荷后无改变；

Conclusion Oral ACZ before SPECT imaging is a simple, reliable way for early diagnosis in patients with TIA.

结论口服ACZ脑负荷试验方法简单可靠，对TIA患者早期的影像学诊断有重要价值。

Objective In order to assess the diagnostic value of acetazolamide ( ACZ) combined with rCBF SPECT imaging in patients with transient ischemia attack ( TIA).

目的评价口服乙酰唑胺（ACZ）脑负荷试验SPECT脑灌注显像对短暂性脑缺血发作（TIA）患者的诊断价值。

The dnaA gene with LacZ promoter was cloned into pUC 19 using the Escherichia coli DH 5 a strain.

将带有LacZ启动 子的dnaA基因构建到pUC19中,得到重组质粒pUCA12.
