The experiments on isolated nerve fibers from the frog Rana ridibunda have demonstrated that aminoacridine tacrin and aminocholine amiridine given in a concentration of 1 microM induced a 3-4 mV increase in the resting potential of the intact Ranvier

Experiments by the voltage clamp method showed that external application of quinidine (5 × 10−5 M) to the Ranvier node membrane of the frog nerve fiber inhibitis both sodium and potassium currents. Blocking of the sodium current is considerably in

A routine procedure for dissection of single nerve fibres with sharpened sewing needles is rather tiresome and occasionally traumatic because of poor efficiency in cutting interfibrous connective tissue and sticking out patches of it to preparative n

The effects of quinidine on sodium (INa) and potassium (IK) currents in the Ranvier node of frog myelinated nerve fibre was studied by means of voltage clamp technique. When applied externally quinidine (5.10(-5) M) suppresses both INa and IK. Inhibi

The indole alkaloid yohimbine (40 microM in the outside solution) is shown to reduce the intramembrane charge transferred by the asymmetric displacement current in the frog Ranvier node by 40%, the sodium permeability being inhibited by more than 90%

The effect of prospidin on Lewis lung carcinoma spreading under hyper- and hypocalcemia was studied. At early stages, increased extracellular calcium level was associated with inhibition of tumor dissemination to the lungs; however, later, colony gro

Measurements were carried out by the method of double succrose gap. Accommodation was practically absent in all the preparations studied: the minimal gradient was not observed, the mean value of accommodation was 0.02 rheobasa/s, saturation current/H
