摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗提供一种慢性肾脏病血管钙化小鼠模型的建立方法。
〖HTH〗方法〖HTSS〗〖KG*2〗利用昆明种小鼠,采用腺嘌呤联合维生素D3,配合高磷饮食,建立慢性肾脏病血管钙化模型。
〖HTH〗结果〖HTSS〗〖KG*2〗以腺嘌呤联合维生素D3,配合高磷低蛋白饮食喂养小鼠6周后,模型组60只小鼠中,死亡6只,10只小鼠胸主动脉发生明显钙化(成功率约17%);模型小鼠血清中尿素氮、血肌酐、尿酸、血磷和血钙均较对照小鼠显著增加(P<005)。未发生明显钙化的小鼠血管均发生血管壁明显增厚、中层纤维变形的血管病变。
〖HTH〗结论〖HTSS〗〖KG*2〗采用腺嘌呤联合维生素D3和高磷饮食6周可导致慢性肾病血管钙化。 此方法简便易行、成模时间短、稳定性好,适于慢性肾病及血管钙化的研究。

Abstract: [Abstract] Objective〖HTSS〗〓To establish vascular calcification mouse model derived from chronic kidney disease(CKD).
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Murine CKD was induced by oral dosing with adenine. 1,25(OH)2D3 and highphosphate diet were used to accelerate vascular calcification. Serum urea nitrogen, serum creatinine, uric acid, calcium and phosphate were measured. HE staining and Von kossa staining were used to examine the morphological changes in kidney and aorta, respectively.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓After adenine dosing combined with 1,25(OH)2D3 and highphosphate diet, significant aortic calcification was detected in about 17% animals at 6 weeks, significantly increased serum urea nitrogen, creatinine, uric acid, serum calcium and phosphate were observed  and all model animals showed significant arterial wall thickening and increased medial elastic fibers.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓These data suggest that mice dosed orally with adenine in combination with 1,25(OH)2D3 and highphosphate diet were able to develop severe CKD and vascular disorder. The research provide a simple and stable mice modet to study vascular calcification in chronic kindney disease.
