[Characteristics of the vascular reactions of rabbits to prolonged stimulations in experimental atherosclerosis].
The constrictory reactions to long electrostimulation of renal, pulmonary femoral arteries and distal aorta segments of intact rabbits getting 200 mg/kg of holesterine during 4-12 months have been compared. It has been established that all artherosclerotic vessels exhibit higher initial amplitude of constriction using as indicator of phasic reactions. the tetanus stability increases, that expresses in longer conservation of initial constriction amplitude on relatively high level; this is evidence of vessels capacity to long tonic reactions. These changes of aorta and pulmonary vessels were more distinct.
