Levels of Scr (A), BUN (B), renal calcium (C), and urine Ca/creatinine (D) were determined (**P<0.01 oxalate group compared with saline group, ^#P<0.05, ^##P<0.01 FFJQC group compared with oxalate group). All data are expressed as the mean ± S.D. (E) Concentration of CAT in the kidney, (F) concentration of SOD in the kidney, (G) concentration of GSH in the kidney, (H) concentration of MDA in the kidney. (A) **P=0.0002 Oxalate group compared with Saline group, ^##P=0.0081 FFJQC group compared with Oxalate group; (B) **P<0.0001 Oxalate group compared with Saline group, ^#P=0.0177 FFJQC group compared with Oxalate group; (C) **P<0.0001 Oxalate group compared with Saline group, ^##P=0.0004 FFJQC group compared with Oxalate group. (D) **P<0.0001 Oxalate group compared with Saline group, ^##P=0.0139 FFJQC group compared with Oxalate group; (E) **P=0.0005 Oxalate group compared with Saline group, ^##P=0.0447 FFJQC group compared with Oxalate group; (F) **P=0.0014 Oxalate group compared with Saline group, ^##P=0.0947 FFJQC group compared with Oxalate group; (G) **P=0.0007 Oxalate group compared with Saline group, ^##P=0.0014 FFJQC group compared with Oxalate group; (H) **P<0.0001 Oxalate group compared with Saline group, ^##P=0.0019 FFJQC group compared with Oxalate group.
