Effect of peripheral blockade of cholinergic muscarinic and α-, β-adrenergic receptors on HVGC elicited by centrally administered insulin in conscious Wistar rats. (A) Basal levels of hepatic glucose (mg/dL) prior to pretreatment with adrenergic (phentolamine; PHENT + propranolol; PROP) and cholinergic (atropine methyl-bromide; ATROP) antagonists. (B) Percentage (%) and area under the curve (AUC, panel (C) HVGC after administration of insulin (n = 5) and/or denatured insulin (vehicle control, n = 5) into the lateral ventricle of Wistar pretreated with ATROP (n = 5) or PHENT+PROP (n = 5) intravenously. One-Way ANOVA; P < 0.05 & P < 0.001. NS = not significant.
