Studies have consistently shown a lower cardiovascular risk in women who received postmenopausal hormone replacement therapy (HRT).
In this study, the effects of HRT were investigated on plasma total homocysteine (tHcy) and the oxidant-antioxidant status in postmenopausal women. 35 of postmenopausal receiving (2 mg estrodiol valerate + 1 mg cyproterone acetate) HRT group, the remaining 25 received orally placebo (NHRT group).
There was no significant change in plasma tHcy levels between HRT and NHRT groups. Malondialdehyde (MDA) and total thiol (t-SH) correlated significantly with tHcy (0.388 and 0.478, respectively) content, and there was a significant negative correlation between E2 level and glutathione transferase (GST) activity (-0.425) in HRT group. Superoxide dismutase (SOD) and HDL-C correlated significantly with t-SH level (0.339 and 0.336, respectively) in plasma after HRT.
Our results show that HRT is beneficial in the protection against oxidative damage, and prevents atherosclerotic complications.
研究表明,接受绝经后激素替代疗法(HRT)的女性心血管风险较低。
本研究旨在探讨 HRT 对绝经后妇女血浆总同型半胱氨酸(tHcy)和氧化还原状态的影响。35 名接受(2 毫克戊酸雌二醇+1 毫克环丙孕酮)HRT 的绝经后妇女为 HRT 组,其余 25 名接受口服安慰剂(NHRT 组)。
HRT 组和 NHRT 组血浆 tHcy 水平无显著变化。丙二醛(MDA)和总巯基(t-SH)与 tHcy 含量呈显著正相关(分别为 0.388 和 0.478),HRT 组 E2 水平与谷胱甘肽转移酶(GST)活性呈显著负相关(-0.425)。超氧化物歧化酶(SOD)和 HDL-C 与 HRT 后血浆 t-SH 水平呈显著正相关(分别为 0.339 和 0.336)。
我们的结果表明,HRT 有益于预防氧化损伤和动脉粥样硬化并发症。
