Specific binding of the calcium antagonist [3H]verapamil to a microsomal fraction, a presumptive plasma membrane fraction and an intracellular membrane fraction of the phototactic unicellular green alga Chlamydomonas reinhardtii has been demonstrated. The specific activity of the plasma membrane mar
The effects of the calcium channel blockers, verapamil, diltiazem and lanthanum ions and the Ca 2 + dependency on motility as well as the photophobic response (stop-response) of Gyrodinium dorsum were studied. At Ca z + concentrations below 10-3 M, motility was inhibited. La 3 + inhibits the stop-re
Gestational day 11 rat embryos were cultured for 20 h in the presence of nifedipine (NIF), diltiazem (DIL) and verapamil (VER), and the effects of these calcium channel blockers on embryonic heart rate and gross morphology were examined. Reductions of embryonic heart rate were dose dependent and rev
