Pharmacological prevention of cardiovascular aging--targeting the Maillard reaction.

abstract：:1. Tachycardia and bronchodilatation were produced by intravenous dimethylphenylpiperazinium iodide (DMPP) in the spinal or pithed cat. Responses other than those involving beta-adrenoceptors were minimized by appropriate blocking agents.2. With intact adrenals, both the tachycardia and bronchodilatation with 10 mug/k...
