1. The effects of some anions (Br, NO3, I, SCN, substituted for Cl) and cations (TEA, NH4, substituted for Na) on the membrane resistance and twitch tension of frog skeletal muscle fibres were investigated.2. In nitrate-Ringer, both of membrane resistance and twitch tension increased in proportion to the concentration of nitrate.3. The degrees of twitch potentiation by these anions were Cl<Br<NO3<I<SCN. The increasing factor of membrane resistance was also in the same order, the relative values… CONTINUE READING
