Fig. 8From: Modulatory effects of vagal stimulation on neurophysiological parameters and the cellular immune response in the rat brain during systemic inflammation a Leptin plasma concentration 4.5 h after LPS or vehicle administration (n = 5 in the SHAM group and n = 8 in the septic groups). LPS increased leptin plasma levels, which were reduced by vagus nerve stimulation compared to the LPS + VGX group (P < 0.05)Back to article page
