(A) Parenchymal noradrenergic innervation was detected by immunohistochemistry. Single TH immunoreactive fibers were closely associated with brown adipocytes (arrows) and with a small arteriole (a). Scale bar: 10 μm. (B) Bar chart showing the number of parenchymal TH immunoreactive fibers per adipocyte. *P<0.05 versus Eu; #P<0.05 versus Hypo.
