Values represent the mean ± S.D. of 8 rabbits. Statistical significances between the means of different treatment groups were analyzed with SPSS software, and a significant difference was considered at P < 0.05. In the same column, a significant difference (P < 0.05) between groups was shown with different letters, and no significant difference (p > 0.05) between groups was shown with the same letter
