加州杏仁奶对肿瘤患者抗氧化能力及脂质过氧化的影响

Effect of Almond Milk on Antioxidant Capacity in Cancer Patients

为探讨加州杏仁奶对放化疗癌症患者抗氧化能力的影响 ,将 1 0 0名准备放化疗的癌症患者随机分为A、B 2组。A组患者在放化疗开始前 3周服用加州杏仁奶 ,直到放化疗结束。在开始服用时、放化疗开始时及放化疗结束时 ,分别测定患者血清中的过氧化物歧化酶 (SOD)、脂质过氧化物 (LPO)和谷胱甘肽过氧化物酶 (GSH Px)。B组患者在放化疗开始时服用加州杏仁奶 ,至放化疗结束后 3周。其间在放化疗开始时、放化疗结束时及放化疗结束后 3周 ,分别测定患者血清中的SOD、LPO和GSH Px。结果 :A、B 2组放化疗结束时的血清LPO浓度与放化疗开始时相比均明显下降 (P <0 .0 5 ) ;B组放化疗结束时的血清SOD水平与放化疗开始时相比均明显升高 (P <0 .0 5 )。提示 :加州杏仁奶能减少自由基对放化疗患者的损伤 。

The aim was to study the effect of Almond milk on antioxidant capacity in cancer patients. One hundred cancer patients were randomly divided into Group A, who administrated Almond milk from 3 weeks before the outset of trial phase to the end of the trail phase, and Group B, who administrated Almond milk from the beginning of trail phase to 3 weeks after the trail phase. SOD, LPO and GSH-Px were measured in both groups. The LPO level decreased evidently as compared to the beginning of trial phase(P<0.05). The SOD activity of subjects showed a significant enhancement at the beginning of trial phase. Almond milk can reduce the free radical damage in cancer patients.
