Zileuton sodium is an inhibitor of 5-lipoxygenase, and thus inhibits leukotrienes(LTB4, LTC4, LTD4 and LTE4) formation with an IC50 value of 0.5μM [1].
Zileuton sodium has been reported to concentration-dependently inhibit the 5-lipoxygenase activity with an IC50 value of 0.5μM in RBL-1cell lysate. In addition, Zileuton sodium has been found to be a potent inhibitor of LTB formation with an IC50 value of 0.6μM. Furthermore, stimulated with A23187, Zileuton sodium has shown a dose-dependent reduction in LTB4 and 5-HETE generation in rat leukocyte with IC50 values of 0.38μM and 0.31μM, respectively. About 40-fold higher concentrations of Zileuton sodium also reduced the production of PGE2 with a IC50 of 16μM [1].

(第1张图和第2张图是经旋转后方向恰好相反的两张图,上矢状窦等静脉也显示了)
女患,70岁,大专毕业,我院退休药师。7-8年前患脑梗(具体不详)。记忆力差5-6年,近记忆为著,几次做饭后忘记关火,将炉具的台板(玻璃的)烧裂。近5-6年来,病人每年住院彻底检查治疗1次(主要是使用活血化瘀及营养脑细胞药)。平素,病人双耳听力略差,睡眠欠佳、便秘、尿频,偶从卧位坐起时视蒙。既往有时血压略高,未降压治疗。本次为“通血管”再来住院。查体:血压:140/80mmHg,双耳听力略差,近记忆力差,但智力(MMSE:26分)正常,颅神经未见异常,四肢肌力、感觉未见异常,植物神经未查,双掌颌反射(+),双下肢病理反射均阴性。血常规:淋巴细胞比率略高,余均正常;尿常规、心电图、癌胚抗原均正常;凝血四项:除凝血酶时间略长外均正常;生化全项:除总胆固醇略高外均正常;超声心动图:老年瓣退行性改变,左室舒张功能减退,房膜瘤可能。彩超:双侧颈动脉粥样硬化形成。头MRA:右大脑中动脉及其分支未显示。
问题:1MRI怎么会这样逍遥?病人无肢体瘫,生活自理如常人。
2为明确头MRA:右大脑中动脉及其分支未显示的病因和程度,除做DSA外,还需做什么?
3如不做DSA,给他订类药、阿斯匹林及活血化瘀的中药可不可以?
教。
