considering the anti-diabetic potential of trigonella foenum-graecum (tfg) and its beneficial effect on aortic reactivity of diabetic rats, this study was conducted to evaluate the effect of its alcoholic seed extract on aortic reactivity and also figure out mechanisms including the role of adrenergic and angiotensinergic systems in streptozotocin-diabetic rats. male wistar rats were divided in...

Pan, Yu-Zhen, De-Pei Li, and Hui-Lin Pan. Inhibition of glutamatergic synaptic input to spinal lamina IIo neurons by presynaptic 2-adrenergic receptors. J Neurophysiol 87: 1938–1947, 2002; 10.1152/jn.00575.2001. Activation of spinal 2-adrenergic receptors by the descending noradrenergic system and 2-adrenergic agonists produces analgesia. However, the sites and mechanisms of the analgesic actio...

Background. (-Adrenergic receptor blockade has been reported to improve hemodynamics and 3-adrenergic receptor-adenylate cyclase function in idiopathic dilated cardiomyopathy. The purpose of this study was to determine the effects of 3-adrenergic receptor blockade on the 13-adrenergic receptor system and myocardial function in a model of compensated ischemic heart failure. Methods and Results. ...

Brain adrenergic system in the feeding response induced by Z-deoxy-D-glucose. Am. J. Physiol. 223(4) : 945-950. 1972.-A reliable eating response was obtained in rats on injection of the glucose analogue, 2-deoxy-n-glucose (Z-DG; 750 " g/kg, ip), which produces decreased intracellular glucose utilization of most tissues and particularly of brain. Intraventricular administration of an a-adrenergi...

Male Wistar rats were divided in...

Introduction: Recent studies showed that nitrergic system have specific modulatory effects on electrophysiological properties of atrioventricular (AV) node. The aim of this study was to determine the effects of nitric oxide (NO) on the electrophysiological properties of isolated rabbit AV node and to investigate the role of adrenergic and cholinergic receptors in the mechanism of its action...

ECG and EEG signals were simultaneously recorded in lizards, Gallotia galloti, both in control conditions and under autonomic nervous system (ANS) blockade, in order to evaluate possible relationships between the ANS control of heart rate and the integrated central nervous system activity in reptiles. The ANS blockers used were prazosin, propranolol, and atropine. Time-domain summary statistics...
