Fig. 7From: Alkaloids from piper longum protect dopaminergic neurons against inflammation-mediated damage induced by intranigral injection of lipopolysaccharideEffects of PLA treatment on the survival ratio of dopaminergic neurons in the SNpc. The numbers of TH-ir neurons in the SNpc were counted as described in methods. Survival ratio of the TH-ir neurons in the SNpc (the injected side relative to the non-injected side) was calculated. n = 4. *** P < 0.001 vs. sham group, ## P < 0.01 vs. LPS groupBack to article page
