Inhibitory effects of DJS on MPP+-induced NO and TNF-α productions in primary mesencephalic cells. After cells were treated with DJS and 15 μM MPP+, the supernatants were activated with Griess reagent and rat TNF-α ELISA kit. The nitrite contents (a) and TNF-α level (b) were determined. Each column represents the mean ± SEM from four replications. Data are expressed as percentages relative to the controls. ^###𝑃<0.001 significantly different from the control group. ***𝑃<0.001, **𝑃<0.01, and *𝑃<0.05 significantly different from the MPP+ only treated group.
