Contractile responses and cryopreservation of human saphenous veins

After cryostorage maximal responses of human saphenous veins to contractile agonists such as 

endothelin-1 (ET-1), 5-hydroxytryptamine (5-HT), noradrenaline (NA), phorbol 12,13-dibutyrate (PDBu)

and potassium chloride (KCl) are diminished by 30 to 50%.
