查询词典 radical expression

Meanwhile the function of antioxidant defense system increased to enhance the ability for clearing free radical and antagonized the damage to organism from free radical. So the activity of GSH-Px and T-AOC enhanced. But the compensative ability was limited and the activity of GSH-Px decreased abruptly and the T-AOC was not increased further in cerebellum of chicken with encephalomalacia. This showed that it existed the exhaustion of GSH-Px in cerebellum of chicken with encephalomalacia.

在体内自由基蓄积的同时，机体抗氧化系统功能出现代偿性增强，提高自由基的清除能力，以对抗自由基对机体的损伤，表现为GSH-Px活性和T-AOC的增强，但机体的代偿能力是有限的，发病雏鸡小脑中GSH-Px活性的突然降低和T-AOC的不再增高，表明GSH-Px在发病雏鸡小脑中存在耗竭现象。

The content of Fe and Cu increased and the content of Zn decreased, the change of the content of Se was consistent with the change of activity of GSH-Px and the content of Ca and Co did not changed in chicken with encephalomalacia The change of Ca and trace element was all relative to the mechanism of free radical The change of Fe ion status showed that Fe acted as medium in the progress of synthesizing free radical.

脑软化雏鸡体内铁、铜含量增高，锌含量降低，硒含量的变化与GSG-Px活性的变化相一致，而钙、钴、锰的含量没有变化。

Both of them showed no toxic effect on mice at the testing dose of 10 mg/kg. The 2,2-diphenyl-1-picrylhydrazyl free radical scavenging test showed that both of the formicary extracts were potent radical scavengers and their scavenging activities were dose-dependent. Furthermore, at higher concentrations (5～10 mg/ml) both of them exhibited significantly higher DPPH scavenging activity than butylated hydroxytoluene.

二苯基三硝基肼(1，1-diphenyl-2-picrylhydrazyl ，DPPH)自由基的清除能力的检测表明：两种蚂蚁窝甲醇提取物都具有显著的自由基清除能力，并呈现出剂量依赖性，而且，在高浓度时(5～10 mg·mL-1)，它们的自由基清除能力甚至显著地高于二丁基羟基甲苯(butylated hydroxyl toluene，BHT)。

The results showed Antioxidant activity was very strong; at the concentration of 0.10g/L, The inhibition rate of superoxide anion free radical(Osuperscript – subscript 4 was 48.45%, The scavenging rate of hydroxyl free radical was 67.52%. Adding 0.1% of the extracts to lard, its antioxidant activity was better than that of 0.02% BHT. The extracts from peel showed higher activities than from juice.

结果表明：荸荠皮提取物的有明显的抗氧化活性，当浓度为0.10g/L时，对超氧离子自由基O(上标–下标 4的抑制率为48.45%，对羟自由基的清除率为67.52%，其0.1%提取物对猪油的抗氧化效果优于0.02%的抗氧化剂BHT，且其活性具有剂量效应关系。

ResultsThe results showed that two extracts of Galla Chinensis had strong scavenging effect on DPPH free radical. The IC50 of scavenging DPPH radical of the water extract and ethanol extract from Galla Chinensis were 0.414 7 mg/L and 0.858 6 mg/L respectively.

结果五倍子两种提取物具有良好的清除DPPH自由基的作用，在实验条件下，五倍子水提取物清除DPPH自由基的IC50为0.414 7 mg/L，五倍子醇提取物清除DPPH自由基的IC50为0.858 6 mg/L。
