2008/1/16
为探讨血管紧张素转换酶（ACE）基因多态性与高血压肾损害和纤溶酶原激活物抑制物-1（PAI-1）的关系，应用聚合酶链反应（PCR）检测96例正常人、67例高血压无肾脏损害患者和70例高血压伴肾损害患者的ACE基因型，采用ELISA法检测血浆PAI-1。ACE基因I/D多态性与高血压病无明显相关，但高血压肾损害患者DD基因型频率及D等位基因频率显著高于对照组和高血压无肾脏损害组，χ2值分别为6.85...
104名藏族志愿者中细胞色素P450 2C19m1的基因多态性Cytochrome P450 2C19 Gene Polymorphism in 104 Chinese Zang Volunteers
2007/12/20
摘要细胞色素P450 2C19（CYP2C19）参与临床上许多重要药物的代谢。根据其代谢S－美芬妥英或其他CYP2C19底物的能力不同，有强代谢者（EMs）和弱代谢者（PMs）之分。PMs表型的频发率存在明显的种族差异。在本文中，我们主要报道了细胞色素P450 2C19 m1在中国藏族人群中的多态性分布。在104例无血缘关系藏族人群中，49人（47.1%）为CYP2C19野生型纯合子（wt/wt）...
