But the levels of 〓 elevation were lower than that in normal Tyrode's solution (P<0.01 respectively), indicating that Ca〓 influx did contribute to the elevation of 〓. Ryanodine remarkably blocked the 〓 elevation by Str 1, 100nmol/L and 10μmol/L in normal Tyrode's solution, while ryanodine 10μmol/L, ruthenium red 10μmol/L and caffeine 10 mmol/L completely blocked the effects of Str on 〓 elevation in Ca〓- free Tyrode's solution (P<0.01 respectively).
