SummaryThis paper reports the inhibitory effects of calmidazolium (CDZ), a calmodulin inhibitor, on electrical uncoupling by CO2. Membrane potential and coupling ratio (V2/V1) are measured in two neighboring cells ofXenopus embryos (16 to 64 cell stage) for periods as long as 5.5 hr. Upon exposure to 100% CO2, control cells consistently uncouple even if the CO2 treatments are repeated every 15 min for 2.5 hr. CDZ (5×10−8−1×10−7m) strongly inhibits uncoupling. The inhibition starts after 30, 50… CONTINUE READING
