雄黄为含硫化砷类矿物药,主要含二硫化二砷(As_2S_2),具有解毒杀虫、燥湿祛痰、抑菌等作用,对一些疑难病症有特殊疗效,特别是偏方验方或一些新疗法中具有一定的应用。临床上经常使用含雄黄的中成药,但雄黄含有对人体有害元素砷,往往由于中药剂量的不确定和使用时间过长而造成患者砷中毒,因此有必要建立稳定准确、灵敏方便的生物样品中雄黄的检测手段,测定服用雄黄后体液中砷的含量进行药物动力学研究和治疗药物监测

半胱氨酸基天冬氨酸蛋白酶-caspase在细胞凋亡中发挥着重要作用,通常当caspase蛋白酶活力受到抑制时,细胞凋亡受到抑制。实验室以前研究表明冬凌草甲素能够显著诱导多种癌细胞凋亡,凋亡过程中caspase的抑制剂均起到抑制凋亡的作用,然而在冬凌草甲素诱导小鼠成纤维肉瘤细胞L929细胞凋亡中caspase家族及caspase-3抑制剂均增强了冬凌草甲素对L929的细胞毒的作用,因此本文对此特殊现
