METHOD Prospectively, 102 patients were treated randomly with either GTN ointment (0.2%) or DTZ ointment (2%) couple of times daily for 12 weeks. RESULTS Forty-five patients (88.2%) in group DTZ...

A common polymorphism (825 C/T) in exon 10 of the GNB3 gene, that encodes for the -3 subunit, has been associated with different degrees of activation of heterotrimeric guanine nucleotide binding proteins (G proteins). Many hormones and neurotransmitters use specific receptors that interact noncovalently with G proteins in the transmembrane signaling process. Among them, insulin uses an inhibit...

OBJECTIVE To examine the effects of exogenous L- and D-arginine on coronary stenosis vasomotion in relation to stenosis morphology. DESIGN Intracoronary infusions of normal saline, L- and D-arginine (50 and 150 micromol/min), and glyceryl trinitrate (250 microg bolus) were given in 24 patients with coronary artery disease and stable angina. Coronary stenoses were classified as smooth or compl...

Nine patients with severe coronary artery disease and disabling angina receiving either regular metoprolol or oxprenolol, together with glyceryl trinitrate tablets as required for chest pain, were studied.
