Normal	1.63±0.12	83.47±6.86	130.91±7.83	7.07±0.21	0.87±0.12
Model	9.32±0.19	24.18±3.28	34.18±4.25	1.97±0.18	5.12±0.36
Vc	4.11±0.36	58.71±4.83	79.36±4.83	4.02±0.22	2.76±0.19
PSLKDT-L	7.02±0.28	39.82±5.19	55.01±3.83	2.83±0.16	3.41±0.23

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).
