“The effect of higher doses of Ni2+ (2.0-20.0 mg/kg-1) was reversed by verapamil , i.e. high doses of exogenous NiCl2 increased CBF and BC in the presence of verapamil.”
“ Verapamil totally abolished the coronary blood flow (CBF) and basal conductance (BC) decreasing effect of low doses of Ni2+ (0.02-0.2 mg/kg-1).”
