Values presented are the mean ± standard deviation (N=10/group). Mean values with different letters over the same column are significantly different (p<0.05) according to Duncan’s multiple range test. Vc: mice treated with vitamin C (100 mg/kg); PSLKDT-L: mice treated with low concentration of polyphenol of small-leaved Kuding tea (50 mg/kg); PSLKDT-H: mice treated with high concentration of polyphenol of small-leaved Kuding tea (100 mg/kg).
