Diabetes:终生补充大剂量维生素D3可安全预防小鼠糖尿病

2014-02-27 高晓方 译 医学论坛网

欧洲一项研究表明,在非肥胖糖尿病(NOD)小鼠中,通过膳食终生补充大剂量维生素D3可安全预防糖尿病。论文2月18日在线发表于《糖尿病》(Diabetes)。 此项研究在NOD小鼠的妊娠和哺乳期、早期(3~14周)以及终生(3~35周)给予大剂量常规维生素D3(800 IU/d)膳食补充,并评估了不同阶段补充维生素D3能否安全预防小鼠糖尿病。 结果显示,仅终生补充可将血清25-羟维生素D3由17

欧洲一项研究表明,在非肥胖糖尿病(NOD)小鼠中,通过膳食终生补充大剂量维生素D3可安全预防糖尿病。论文2月18日在线发表于《糖尿病》(Diabetes)。

此项研究在NOD小鼠的妊娠和哺乳期、早期(3~14周)以及终生(3~35周)给予大剂量常规维生素D3(800 IU/d)膳食补充,并评估了不同阶段补充维生素D3能否安全预防小鼠糖尿病。

结果显示,仅终生补充可将血清25-羟维生素D3由173 nmol/L升高至290 nmol/L,并可在雄性和雌性NOD小鼠中均可显著减少糖尿病形成,同时未诱发钙血或骨毒性征象。维生素D3预防糖尿病与胰腺胰岛素含量正常和胰岛炎评分改善具有相关性。维生素D3治疗使用胰腺引流淋巴结内干扰素-γ阳性CD8+ T细胞减少,并使CD4+(CD25+)FoxP3+ T细胞增多。
