Fig. 4From: Regulating autonomic nervous system homeostasis improves pulmonary function in rabbits with acute lung injuryInflammatory cell infiltration and vascular permeability changes induced by HCl aspiration in groups with different treatments. a, BAL total cell count; b, BAL PMNs (%); c, BAL total protein; d, lung wet/dry ratio. For control group (n = 8), rabbits only received saline intratracheally injection (2.8 ml/kg) after surgery; for HCl groups (n = 8), ALI model was established by intratracheal injection of HCl (pH 1.5, 2.8 ml/kg); for VNS groups (n = 8), after the ALI model established by HCl, rabbits also received constant voltage stimuli (5 V, 2 ms, and 1 Hz); for THA group (n = 8), after ALI model established by HCl, rabbits also received THA (3 mg/kg) intravenous injection; and for SGB group, after ALI model established by HCl, rabbits also continuously received 0.25% bupivacaine pumping via epidural catheter (3 mg/kg). BAL, bronchoalveolar lavage; PMNs, polymorphonuclear neutrophils; VNS, vagus nerve stimulation; THA, tetrahydroaminoacridine; SGB, stellate ganglion block; * P < 0.05, compared to the control group; †P < 0.05, compared to the HCl groupBack to article page
