文摘The inhibiting effects of CHinonin,Quercetin and Tannic Acid on the lipid oxidation (LPO) induced by irradiation were investigated by means of a modified TBA spectrophotometry.The scavenging effects of theses three active compounds on free radicals were studied by ESR technique.The results showed that antioxidation effects of Chinonin and Quercetin were better than that of Tannic Acid;though scavenging effects of the threee active compounds were similar.
文摘60例慢性阻塞性肺病(COPD)、肺心病病人血清脂质过氧化物(LPO)明显高于对照组水平,而超氧化物歧化酶(SOD)明显低于对照组水平。经维生素 C 和刺五加联合治疗后,COPD、肺心病病人血清 LPO 明显低于常规治疗组水平,而 SOD 明显高于常规治疗组水平。提示 COPD、肺心病与自由基所致氧化性损害有关,而且抗氧化剂维生素 C 和刺五加治疗能有效地抑制脂质过氧化和增强抗氧化防御能力。
