ABSTRACT
Objective To observe the effects of phlorizin on aorta of diabetes db/db mice and to explore its mechanism.Methods Sixteen diabetes db/db mice were randomized into two groups:untreated diabetic group (DM group) and diabetic group treated by phlorizin(DMT group) with eight db/m mice as normal control group(CC group).Phlorizin (20 mg/kg) was given in normal saline solution intragastrically to the mice of the DMT group for 10 weeks.Mice of the other two groups were given the same amount of saline solution intragastrically for 10 weeks.Animals were weighed weekly.At 10th weekend,all mice were fasted overnight and then sacrificed.Fasting blood was collected,and aortas were dissected.The blood samples were analyzed for fasting blood glucose (FBG),triglycerides (TG),total cholesterol (TC),Serum advanced glycation end products(AGEs)and malondialdehyde (MDA).Aortic tissue were examined microscopically.Results At 10th weekend,the weight (57.53±3.40)g and serum concentration of FBG(31.21±2.16) mmol/L,TG (0.39±0.12) mmol/L,TC(3.15±0.30)mmol/L,AGEs (0.28±0.04) AU/mg and MDA (15.18± 1.60)mol/L in DM group were increased than those in CC group (P<0.01),and the weight(54.24± 1.28)g,FBG(29.17±1.41) mmol/L,TG(0.26±0.06) mmol/L,TC(2.71±0.26) mmol/L,AGEs (0.24±0.03) AU/mg and MDA(13.46±1.28)mol/L were lowered significantly in DMT group than those in DM group (P<0.05 or P<0.01).The severity of aorta damage in DMT group was less than that in DM group.Conclusions Phlorizin can protect the db/db mice from diabetic macrovascular complications,which may be attributed to its decreasing of blood glucose,TG,TC,and AGEs levels,and its antioxidant potential.
