title: [Diffusion of water through the narrow pores of biomembranes].
abstract: The pulsed-gradient, nuclear magnetic resonance method has been used to study diffusion of water through the cell membranes. An analytical expression is derived for relative amplitude of nuclear spin-echo, describing the diffusion of water in membrane pores. The latter are so narrow, that their diameter is only a little greater than the water molecule diameter. The experimental data for consumed yeast with normal content of water agree well with the theoretical dependence.
