oxidopamine and Cardiomegaly

oxidopamine has been researched along with Cardiomegaly in 6 studies

Oxidopamine: A neurotransmitter analogue that depletes noradrenergic stores in nerve endings and induces a reduction of dopamine levels in the brain. Its mechanism of action is related to the production of cytolytic free-radicals.
oxidopamine : A benzenetriol that is phenethylamine in which the hydrogens at positions 2, 4, and 5 on the phenyl ring are replaced by hydroxy groups. It occurs naturally in human urine, but is also produced as a metabolite of the drug DOPA (used for the treatment of Parkinson's disease).

Cardiomegaly: Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.

Research Excerpts

ExcerptRelevanceReference
" The effects of isoproterenol (ISP) and chemical sympathectomy (6-hydroxydopamine treatment) on myocardial beta-receptors were also investigated in 10 and 24 week-old SHRS and WKY to examine the effects of hypertension and aging on receptor regulation."3.68Effects of aging and drugs on myocardial beta-adrenergic receptors in M-SHRSP and SHRSP. ( Ikawa, H; Suzuki, A, 1991)
"Metoprolol-treated SHR showed a trend toward higher capillary numerical densities consistent with their attenuation of hypertrophy."1.28Sympathetic nerves modify mitochondrial and capillary growth in normotensive and hypertensive rats. ( Tomanek, RJ, 1989)
