抄録

Long-range interaction between membranes in water is discussed along the line of the theory presented by the writers (J. Colloid Interface Sci. 63, 525 (1978)). Explanation is given on the phenomena reported by Inoko et al. (Biochim. Biopnys. Acta 413, 24 (1975)): there appear the four states I, II, III, and IV in the dipalmitoyl lecithin/water systems by addition of CaCl2 with a hysteresis in the I-II transition and the three states I, III, and IV in MgCl2 solutions. Calculated periods of the lamellar phase are in fairly good agreement with experimental data. Inter-membrane interactions are effective beyond 100Å-260Å in suitable conditions. There seems to be a rigid hydration layer with the thickness of about 11Å on the dipalmitoyl lecithin membrane at room temperatures. Discussion is made on ion adsorption on the membrane surface.
