Fig. 2From: Phenolic-rich fraction of green tea attenuates histamine-mediated cardiopulmonary toxicity by inhibiting Cox-2/NF-κB signaling pathway and regulating oxidant/antioxidant balanceBar graphs demonstrating the effects of HIS on various oxidant and antioxidant markers in the homogenates of cardiopulmonary tissue. a Malondialdehyde (MDA), b reduced glutathione (GSH), and c catalase activity. Means ± SEM are used to represent values (n = 5). Various superscript letters (a, b, c, etc.) indicate a significant difference between groups at P ≤ 0.05Back to article page
