Polydatin ameliorated lipid and glucose metabolism and protected the liver from steatosis in db/db mice. a Fasting blood glucose levels (FBG) were measured every other week. b–d In the liver (n = 6), glycogen, TC and TG levels were determinated as described in “Methods”. e Histochemical analysis of fresh liver tissue was performed by staining with H&E or Oil Red O (×400 magnification). ***p < 0.001 vs. C57; ^# p < 0.05, ^## p < 0.01 and ^### p < 0.001 vs. db/db, cv center vain
