Determination of Antioxidant

Determination of Antioxidant Capacity Using the

Biological System Bacteriophage P22/Bacterium

Salmonella typhimurium (標題)

Bacteriophage/bacterium systems have been employed in the past in assays for virucidal activity. A

novel application of one such system is proposed here for the in vivo determination of antioxidant

capacity. It was shown that an antioxidant such as gallic acid can effectively protect against oxidative

damage brought about by H2O2sbut only within a narrow range of concentrations (i.e., from 250 to

500 mg L-1); ascorbic acid, on the other hand, did not exhibit any protective effect against H2O2.

Finally, neither ascorbic nor gallic acid demonstrated a virucidal effect. The P22/Salmonella

typhimurium model system thus proved to be useful in the assessment of antioxidant capacity in

vivo, at least using those two alternative model antioxidants.

幫忙翻一下 謝謝

    標題:利用生物系統Bacteriophage P22/Bacterium

    Salmonella typhimurium決定抗氧化容量

    Bacteriophage/bacterium系統在過去常被用在測定消滅病毒的活動力上。這裡提出一個此類系統的新應用,用在活體內測定抗氧化的容量。它顯示出像蒜酸這類的抗氧化物可以有效地對抗雙氧水產生的氧化傷害,而且只在一定的濃度範圍之內有效(每公升250到500毫克)。而另一方面,抗壞血酸則沒有顯示出對抗雙氧水的能力。最後,不論抗壞血酸或是雙氧水都沒有顯示出消滅病毒的效果。所以可以證明P22/Salmonella typhimurium模型系統在估計活體內的抗氧化容量是很有用的,至少是在使用這兩個替代的標準抗氧化劑上。

    ps:英文部分是專有名詞,因為我不是學生化的,無法幫你翻。另外如果你是學這方面的,這種名詞還是保留原文來記會比較好。
