The effect of piracetam on lipid peroxidation (LPO) in the rat brain was investigated. Piracetam was shown not to catalyze LPO and not to stimulate production of active forms of oxygen but to increase LPO only in the presence of traces of transition of metal ions. In all probability, the reason of this is the capacity of piracetam to chelate these metals. In this case their catalytic activity with respect to LPO increases. The performed studies demonstrate that the observed increase in LPO in the rat brain during the use of piracetam is an artefact due to the presence of traces of transition metal ions.
研究了吡拉西坦对大鼠脑脂质过氧化(LPO)的影响。结果表明,吡拉西坦不催化LPO,也不刺激活性氧形式的产生,只是在存在痕量过渡金属离子时才会增加LPO。很可能,其原因是吡拉西坦具有螯合这些金属的能力。在这种情况下,它们对LPO的催化活性增加。所进行的研究表明,在使用吡拉西坦期间大鼠脑中观察到的LPO增加是由于存在痕量过渡金属离子而产生的假象。
