The blockade of serotoninergic receptors with methysergide or the activation of alpha(2)-adrenoceptors with moxonidine into the lateral parabrachial nucleus (LPBN) increases water and 0.3 M NaCl intake in rats treated with furosemide (FURO) combined with captopril (CAP). In the present

1. The binding of a new alpha 2-adrenoceptor antagonist, [3H]-RX821002 (2-(2-methoxy-1,4-benzodioxan-2-yl)-2-imidazoline), was investigated in human platelet membranes and compared with [3H]-yohimbine binding parameters. 2. Analysis of kinetic data revealed association and dissociation time courses consistent with a simple biomolecular reaction.

We have investigated the distribution of alpha-adrenoceptors in sheep internal anal sphincter (IAS), as a model for the human tissue, and evaluated various imidazoline derivatives for potential treatment of faecal incontinence. Saturation and competition binding with (3)H-prazosin and (3)H-RX821002 were

To test for alpha(2) adrenergic modulation of dopamine D(2/3) receptor availability in striatum of living mice using the high-affinity ligand [(18)F]fallypride and microPET. Groups of anesthetized mice were pretreated with saline, the alpha(2)-agonist clonidine (1 mg/kg), and the alpha(2)-antagonists RX821002

The brain stem provides most of the noradrenaline (NA) present in the spinal cord, which functions to both increase spinal motoneuron excitability and inhibit sensory afferent transmission to motoneurons (excitatory postsynaptic potentials; EPSPs). NA increases motoneuron excitability by facilitating calcium-mediated
