Average
Values are mean ± SD, I = daily, II = once a week, and III = alternatively. Values with similar superscripts in a column for four days of application (a or b) and for average values (A, B, or C) at each mode of application indicate no significant difference. Values with different superscripts in a row for each sex for four days of application (a-b) and for average values (A–C) at each mode of application indicate significant difference at .
