abstract：:Insulin seems to have the ability to suppress the production of tumor necrosis factor-alpha and superoxide anion, enhance the synthesis of nitric oxide and inhibit the expression of intercellular adhesion molecule-1 (ICAM-1) through stimulation of nitric oxide. This suggests that insulin can behave as an anti-inflamma...
