Abstract:

This experiment was conducted to study the effect of the bacterial enriched-selenium polysaccharide enterobacter cloacaeZ0206 on the renal disease of the Type Ⅱ diabetic KKAy mice.Six to eight week-old male KKAy mice were allocated in diabetes group (Model),Z0206 bacterial enriched-selenium polysaccharide group (CEPS) and Z0206 purified enriched-selenium polysaccharide group (PEPS) based on the blood glucose concentration after two weeks pre-feeding,8 mice in each group.The groups received 0.5 mL distilled water,10 mg·mL-1 CEPS,10 mg·mL-1 PEPS respectively.Eight 7-week-old C57/BL mice were used as normal control group (Control).The feeding trial lasted for 42 days.Compared with the control group,the activity of Glutathione Peroxidase (GSH-Px) and Superoxide Dismutase (SOD) in Model group were significantly decreased (P<0.05),the mRNA transcription of interleukin-1 (IL-1),interleukin-6 (IL-6),monocyte chemotactic protein 1 (MCP-1),nuclear factor-κB (NF-κB),transforming growth factor-β (TGF-β),plasminogen activator inhibitor 1 (PAI-1),plateletderived growth factor β (PDGF-β) and Collagen Type Ⅳ (Col-Ⅳ) were significantly increased (P<0.05).The level of MDA were significantly increased (P<0.05).Compared with the Model group,the enriched-selenium polysaccharide groups resulted in significant repair effect,the activity of GSH-Px and SOD in both polysaccharide groups were significantly increased (P<0.05),the mRNA transcription of IL-1,IL-6,MCP-1,NF-κB,TGF-β,PAI-1,PDGF-β and Col-Ⅳ were significantly decreased (P<0.05),the level of MDA were significantly decreased (P<0.05),matrix proliferation was significantly reduced.It is suggested that the polysaccharide can enhance the antioxidant function of the Type Ⅱ diabetic KKAy mice and repair the damage caused by diabetes to it.
