To study the changes between SOD activity and LPO content in serum of the patients with cholecystolithiasis before and after operation, the methods of xanthine oxidase and thiobarbituric acid were applied to this study.

为研究胆囊结石患者血清中超氧化物岐化酶活性水平、过氧化脂质含量及其变化规律，应用黄嘌呤氧化酶法和硫代巴比妥酸法测定了48例胆囊结石患者手术前后血清中SOD活性和LPO含量。

The main reason: too long, or is affected by the activities of acids, alkalis, sulfur and other chemical substances of erosion and chromotropic, and the other color ink series.

主要原因：调和时间过长，受氧化作用或受酸、碱、硫等化学物质的侵蚀而变色，与其他墨色串色。

Proteins associated with the membrane and the cytosolic portions of the proteome under different copper ion concentrations were differentially labeled with an acid cleavable isotope-coded affinity tag reagent, and the labeled peptides were separated by two-dimensional chromatography and characterized by electrospray ionization-tandem mass spectrometry.
