摘要: 目的 观察维生素D3(VitD3)中毒剂量下对大鼠的血液及肾脏生化指标的影响。方法 SPF级SD大鼠随机分为正常对照组、VitD3低剂量组(1 875 IU/kg组)、VitD3中剂量组(3 750 IU/kg组)、VitD3高剂量组(7 500 IU/kg组)和VitD3超高剂量组(15 000 IU/kg组), 每日灌胃(ig)1次, 连续3周, 实验结束,检测相关指标。结果 各组大鼠血清中尿素氮(BUN)和肌酐(Cre)随着剂量降低呈明显下降、血清Ca2+含量随着剂量增加呈明显上升,超氧化物歧化酶(SOD)含量随着剂量增加逐渐降低; 大鼠血清丙二醛(MDA)含量随着剂量增加逐渐升高; 各组肾组织Ca2+含量随着剂量增加逐渐升高、MDA含量在 1 875 IU,7 500 IU时,与对照组比较差异无统计学意义。结论 VitD3在7 500 IU/kg,15 000 IU/kg的剂量时,对实验大鼠的肾功能生化指标BUN、Cre及血清Ca2+含量均有明显影响,表明Vit D3在此剂量范围内,是引起实验大鼠肾脏毒性的剂量。

Abstract: Objective To observe the effects of vitamin D3 (VitD3) at toxic dose on the blood and renal biochemical indicators of rats. Methods The specific pathogen free SD rats were randomly divided into five groups: control group, low dose VitD3 group (1 875 IU), medium dose VitD3 group (3 750 IU ), high dose VitD3 group (7 500 IU), and super high-doseVitD3 group (15 000 IU). They were intragastric administration once a day for 3 weeks.The relevant indicators were detected after treatment finished. Results Serum blood urea nitrogen (BUN) and Creatinine (Cre) decreased significantly with the dose decreasing, and the content of serum Ca2+ increased significantly with the dose increasing. The content of superoxide dismutase (SOD), and serum malondialdehyde (MDA) decreased with the dose increasing. In renal tissue, the content of Ca2+ gradually increased with the dose increasing, and there was no significant difference in MDA at the dose of 1 875 IU and 7 500 IU. Conclusions At the dose of 1 875 IU to 15 000 IU, VitD3 has significant effects on the renal biochemical indicators such as BUN, Cre and serum Ca2+, indicate that the dose range 1 875 IU to 15 000 IU can induce renal toxicity in experimental rats.
