The effects of silymarin on the inhibition of nonenzymatic glycation and oxidation in aorta of streptozocin-induced diabetic rats / 第二军医大学学报

ABSTRACT

To investigate the inhibitory effects of silymarin on diabetic blood vessels chroniccomplication. Methods:Silymarin was given to streptozocin-induced diabetic rats. Rats were killed 9 weeksafter treatment. Plasma LPO, fructosamine and RBC-SOD were measured. LPO, fruct0samine, fluores-cence intensities of AGEs, pentosidine and liperperoxide adducts in aorta were also measured. Results:The early nonenzymatic glycation products-fructosamine were not inhibited, however, LPO and f1uores-cence intensities of AGEs, pentosidine,MDA and HNE adducts in aorta were more significantly reducedthan DM group. Conclusion: The results suggest that silymarin may inhibit nonenzymatic glycation andoxidation in aorta of streptozocin-induced diabetic rats and control the diabetic chronic complication.
