HEA-pABA, pABA and HEA treatments at different concentrations in comparison with control are shown. Control corresponding to pABA was noted CONTROL 0.2% EtOH and for HEA-pABA and HEA, CONTROL. Values with different letter annotation are significantly different (P<0.05). Data are means ± SE of 5 replicates.
