Note: in the same row, values with different small letter superscripts mean significant difference (P < 0.05); values with different capital letter superscripts mean significant difference (P < 0.01); Values with no letter or the same letter superscripts mean no significant difference (P < 0.05). Values are expressed as mean ± SEM, and n = 6 for all groups.
