Values are the mean ± SD.The Mann-Whitney U- test was used to assess the statistical significance of differences between the two groups.^a Erythrocyte count
Samples were scored from 0 to 3 according to the level of damage with 0 representing normal, 1 mild, 2 moderate, and 3 severe morphologic changes
