Fig. 2. Lig suppresses inflammation and apoptosis in DN. (A–D) The levels of proinflammatory cytokines (IL-8, IL-6, IL-1β and TNF-α) in kidney homogenate were estimated by specific ELISA kits. (E) Apoptosis index was determined by TUNEL assay. The bars showed means ± SD of three independent experiments. *P < 0.05 compared with control group, #P < 0.05 compared with STZ-induced model group.
