Figure 4: Effects of DND on serum biochemical parameters. Activities of serum aminotransferase including AST and ALT were assayed in consistence with the instruments of commercial test kits. LDH and CK levels in the serum were also measured according to the methods described by the protocols of commercially available standard kits. All values given are the mean ± SD. #P<0.05 and ##P<0.01 versus control group. P<0.05 and P<0.01 versus CTX- group.
