Compared with those in the rats in the CON group, the protein levels of nNOS (Figure 8(a)), ChAT (Figure 8(b)), and PGP9.5 (Figure 8(c)) in the rats in the DM group decreased (P < 0.01), and EA increased the protein levels of nNOS, ChAT, and PGP9.5 in the T2DM rats (P < 0.05). Here, CHAT is linked to type 2 diabetes mellitus.
