ABSTRACT
Studies by EPR spectroscopy showed that 30-day exposure of rats to augmenting hypokinesia led to a 3-fold increase in nitric oxide (NO) production in the heart and 2-fold in the liver. These results indicated that long-term hypokinesia stimulated NO synthesis.

ABSTRACT
In adult sympathectomized rats the right and left vagus nerves exhibited asymmetric effects on heart rate and strength of cardiac contractions. After vagotomy, the heart rate and stroke volume remained high in sympathectomized rats, but returned to normal in intact animals. The sympathetic nervous system plays a role in postvagotomic tachycardia. Sympathectomized rats were characterized by higher reactivity of cardiac beta-adrenoceptors to propranolol compared to intact animals.
