Figure 5From: Activation of κ-opioid receptor by U50,488H improves vascular dysfunction in streptozotocin-induced diabetic ratsU50,488H suppressed DM-induced inflammatory response through NF-кB inhibition. ELISA analysis showed significant increases in serum levels of IL-6 (A), IL-8 (B), and sICAM-1 (C) in DM rats as compared with the CON group, and U50,488H treatment prevented these increases. (D) NF-κB p65 translocation was increased in DM rats as compared with the CON group, which was markedly attenuated by U50,488H treatment. *P < 0.05 vs. CON group, #P < 0.05 vs. DM group.
