Growth behaviour of myelin figures, which are a rod like texture formed in a lyotropic liquid crystalline system in smectic A phase with structure analogous to nerve myelin sheath, was investigated by means of optical microscopy. Myelin figures grow at the interface between an amphiphilic compound and an aqueous medium on contact of the two. The systems studied here were of egg-yolk lecithin (egg-PC) and water and egg-PC and ethylene glycol (EG). The diameter of myelin rods observed for egg-PC/EG system did not exceed 40 μm at room temperature, when the thickness of the growing space was sufficiently larger than 40 μm. For the thickness smaller than 40 μm, the diameter of rod was determined by the thickness of the space. The effect of doping aromatic compounds to egg-PC was also studied for egg-PC/water systems. The observed texture of myelin figures were modified due probably to possible change in surface energy. Preliminary results on the relation between the growth rate of rod and the diameter will be presented.
