摘要 目的探讨高蛋氨酸饮食对雄性大鼠血浆6-酮-前列腺素F1α、血栓素B2含量和PGI2/TXA2系统的影响。方法雄性Wistar大鼠随机分为正常饮食对照组(对照组)和高蛋氨酸饮食组(高蛋氨酸组)。对照组喂饲普通饲料,高蛋氨酸组大鼠喂饲含3%蛋氨酸的高蛋氨酸饲料,共8周。采用高效液相色谱法测定大鼠血浆同型半胱氨酸含量,放射免疫非平衡法测定6-酮-前列腺素F1α(6-Keto—PGFF1α)和血栓素B2(TXB2)含量。结果与对照组相比,高蛋氨酸组血浆Hcy含量显著高于对照组(P〈0.01),是对照组的2倍以上,6-Keto—PGF1α含量显著降低,TXB2含量显著升高(P〈0.01),且PGI2/TXA2比值均显著降低(P〈0.05)。结论高蛋氨酸饮食可诱发雄性大鼠高半胱氨酸血症,PGI2/TXA2失衡。
