We found that CaV 3.two fluorescence improved inside the superficial SDH in PDN rats and reduced in loganin-treated rats (Figure 2A). We also examined the distribution of CGRP. Immunofluorescent imaging was focused on lamina I I as indicated inside the upper proper of Figure two. The pictures showed stronger CGRP fluorescence (Figure 2B) in lamina I I on the SDH in PDN rats than in loganin-treated rats. eight of 17 We investigated the regulatory effect of loganin on astrocyte and microglia activation inside the PDN rats.
