Figure 10.

Representative image of AVP mRNA expression (B) in the PVN and supraoptic nucleus (SON) of the hypothalamus. Semiquantitative analyses revealed that AVP mRNA expression was elevated in the parvocellular PVN of posterior BST lesion rats compared with shams (A) and attenuated in the magnocellular PVN of the anterior BST lesion rats compared with shams (C). No statistical differences in AVP expression were observed in the SON among lesion groups (D). Data are shown as mean ± SEM; n = 7–12. *p < 0.05 versus sham. PVNpm, Posterior magnocellular PVN; SON, supraoptic nucleus of the hypothalamus. Scale bar, 500 μm.
