摘要:

研究一种以一氧化氮合酶底物L-精氨酸和山楂提取物、虾青素和知母宁等天然抗氧化剂为主要成分的配方产品ZPF1对心肌的保护作用.发现,ZPF1显著促进大鼠心肌细胞H9C2细胞增殖,减少苯肾上腺素诱导的活性氧.在异丙肾上腺素(ISO)诱导小鼠心肌肥厚的模型中,喂食100 mg/(kg·d)的ZPF1显著抑制ISO引起的心肌肥厚和功能失常,其机制与上调SERCA2a蛋白有关.这些事实说明,一氧化氮和天然抗氧化剂的组合产品ZPF1对心力衰竭有较好的防治作用.

关键词: 一氧化氮, 天然抗氧化剂, 心肌肥厚

Abstract:

ZPF1 is a new formula that is composed of L-Arg and several natural antioxidants. In this study, the cardioprotective effect of ZPF1 has been investigated. It was found that ZPF1 promotes H9C2 cell growth and decreases intracellular ROS level in phenylephrine-treated cells. ZPF1 also attenuates isoprenaline-induced cardiac hypertrophy and dysfunction in mice, which is due to SERCA2a up-regulation.Our findings suggest that the combination of NO and natural antioxidants serves possible therapeutic intervention against heart failure.

Key words: nitric oxide (NO), natural antioxidants, myocardial hypertrophy
