in rat heart muscle and non-muscle cells , the binding of [ 3h ] ouabain to the low affinity site results in inhibition of the ( 86rb+ + k+ ) -influx ( ec50 = 1.3 and 1.5 x 10 ( -5 ) m ouabain ) , a decrease in cell-k+ ( ec50 = 1.9 and 1.4 x 10 ( -5 ) m ) and an increase in cell-na+ ( 10 ( -5 ) -10 ( -4 ) m ) .
