Fig. 2. The effects of different dosages (0, 12, 120, 600 µg) of udenafil on the expression of toll-like receptor 4 (TLR4) (A), phosphodiesterase 5 (PD5E) (B), myeloid differentiation primary response gene 88 (Myd88) (C), and nuclear factor-κB (NF-κB) (D) mRNA in the hypothalamus in mice. Udenafil was administered via gavage for 2 consecutive days. Data are expressed as mean±standard error of 6 mice in each experimental group. Values that do not share a common superscript letters are significantly different at p<0.05.
