Fig. 2From: Adipose tissue alleviates the stress response by releasing adiponectin during laparoscopic surgery in patients with colorectal cancerSerum levels of glutathione (GSH), superoxide dismutase (SOD), lipid peroxide (LPO), and malondialdehyde (MDA) in the laparoscopic and open surgery groups. A: Comparison of serum levels of GSH. B: Comparison of serum levels of SOD. C: Comparison of serum levels of LPO. D: Comparison of serum levels of MDA. Pre-LS: prelaparoscopic surgery; Post-LS: postlaparoscopic surgery; Pre-OS: preopen surgery; Post-OS: postopen surgery. The data are expressed as the mean ± SD (n = 20). *P < 0.05 and **P < 0.005Back to article page
