摘要

Purpose: To access the oxidative stress in type-2 diabetic patients, by measuring the adenosine deaminase (ADA) levels in serum,co-cultured monocytes, monocyte supernatant, and to verify the modularity effect of antioxidant on ADA levels.Material and methods: Adenosine activity was measured in the serum, 24 hours co-cultured monocytes and cell-free supernatantof the monocytes in 50 type-2 diabetic subjects. 20 age and sex matched healthy subjects were taken as controls. The ADA activitywas reassessed after treating the co-cultured monocytes with antioxidants, namely, N-acetyl cysteine and epigallocatechin-3-gallate (EGCG).Results: Adenosine deaminase levels were found to be raised in monocytes of type-2 diabetic patients. This level decreased afterantioxidant therapy.Conclusion: Adenosine deaminase activity could be regarded as a strong indicator of reactive oxygen species (ROS) productiondue to oxidative stress in type-2 diabetic subjects, which could be modulated by antioxidants
