title: [Distribution of the dimensions of cells and intracellular structures of biosystems from measurements of the diffusion of water by the impulse gradient of the NMR spin echo method].
abstract: The method of impulse gradient of NMR spin-echo was applied for studying limited water diffusion in yeast cells and embryons of wheat caryopsis. Results are presented of measuring the amplitude of the echo signal depending on the intensity of the impulse gradient of the magnetic field reaching the values up to 1.7 kGs/cm. The method is suggested of determining on the basis of experimental data the distribution function parameters of the sizes of limiting cell compartments taking into account the permeability of their walls (membranes).
