Effect of cyclosporine A on myocardial calcineurin activity of the right ventricle and plasma NO,nitric oxide synthase and endothelin-1levels in rats with chronic hypoxia
Objective To study the role of calcineurin in the progression of right ventricle myocardial hypertrophy in rats exposed to chronic hypoxia by examining the effect of Ca 2+ channel blockers on the activation of calcineurin and plasma levels of nitric oxide (NO), NO synthase, and endothelin-1 (ET-1). Methods Rat models of right ventricle myocardial hypertrophy were established by exposing the rats to chronic hypoxia in 10.0%±0.5% O 2 for 7 d. The 24 rat models were assigned into normoxic group, hypoxic ...
