چکیده

In oxygen-aerated non-growing cells a subinhibitory ethanol concentration (1 G/L) causes an H /K exchange. An inhibitory ethanol concentration (30 G/L) slows down acidification but + + has no effect on its extent. The transmembrane pH depends directly on the ethanol level in the medium and is not lowered at high ethanol concentrations. Changes in membrane potential induced by ethanol are also concentration dependent. The high ethanol level does not increase the passive permeability of cell membrane to H . +

Modification of Nifedipine Inhibitory Effect on Calcium Spike and L-Type Calcium Current by Ethanol in F1 Neuron of Helix aspersa

There is strong evidence demonstrating that nifedipine dissolved in ethanol selectively inhibits only L-type Ca2+ current. In addition, acute ethanol exposure reduces voltage-dependent calcium currents. In the present study, we investigated the antagonistic effect of fixed concentration of nifedipine dissolved in different concentration of ethanol on L-type Ca2+ current. In a Na+-K+ free soluti...

بررسی اثر گیرنده های دوپامینی D1 هیپوکامپ پشتی بر روی اثر بهبود بخش نیکوتین روی فراموشی القا شده با اتانول

Background and Objective: Ethanol and nicotine increase dopamine release in different parts of the brain such as the nucleus accumbens and the hippocampus. Dopamine D1 receptors have been detected in dorsal hippocampus known as a key brain region that seems to mediate some behavioral effect of ethanol and nicotine. The present study was carried out to determine the influence of dopamine D1 rece...
