[Method] Four wheat cultivars, including Yunong 51, Zhoumai 22, Jimai 19 and Huaimai 22, were selected as experimental materials and cultured under drought stress simulated by different concentrations of PEG6000, to determine the activity of POD and CAT. [Result] POD and CAT activity in wheat during generation period increased gradual y under stress of 5% and 15% PEG6000 from 0 to 120 h; POD and CAT activity in wheat under stress of 15% PEG6000 increased more compared with that under stress of 5% PEG6000; POD and CAT activity in wheat under stress of 25% and 35% PEG6000 increased first and then decreased. Stress duration significantly af-fected the activity of POD and CAT in wheat during generation period. [Conclusion] This study provided theoretical references for breeding drought-tolerant wheat.展开更多
术后恶心呕吐(postoperative nausea and vomiting,PONV)是围术期影响患者康复质量的常见并发症。在全部住院手术患者中PONV的发生率约为20%~30%,某些高危患者的发生率高达80%。PONV除了引起患者强烈的主观不适,严重者还可以引起伤口裂...术后恶心呕吐(postoperative nausea and vomiting,PONV)是围术期影响患者康复质量的常见并发症。在全部住院手术患者中PONV的发生率约为20%~30%,某些高危患者的发生率高达80%。PONV除了引起患者强烈的主观不适,严重者还可以引起伤口裂开、术后出血、误吸和吸入性肺炎、水电解质平衡紊乱,使患者住院时间延长和医疗费用增加[1-2]。展开更多
