内容記述 In order to investigate the ultrastructure and function of the lateral and third ventricular choroid plexuses, thirty young chicks were used on the three different photoperiods such as the continuous light, continuous darkness and LD 12: 12. 1. The choroidal epithelial cells are cubic to columnar in shape. On the free apical surface the cells possess long digitiform microvilli resembling the absorptive epithelium. The cells also have a few cilia with the 9 plus 2 arrangement. The cytoplasm of the epithelial cells contains single nucleus, numerous mitochondria, rough and smooth endoplasmic reticulum and Golgi complex. Occasionally binucleate cells have been observed. The lateral membranes between adjacent epithelial cells of young chicks are relatively straight and do not take the form of interdigitation as those of rats and pigs. 2. Two kinds of cells in the choroid plexus are found occasionally. They are different from the ordinary epithelial cells. One is the large pale cell and the other is the multipolar dark cell. The large pale cells are spherical in shape and larger than the other epithelial cells, which show extremely low electron density. The multipolar dark cells are exceedingly irregular in shape and show somewhat higher electron density. The surface of the cells did not contact with the ventricular lumen. The multipolar dark cells have some processes which reach between the epithelial cells. 3. The capillaries beneth the epithelium have fenestrations or pores. These structures show that the choroid plexus contributes the cerebrospinal fluid secretion. 4. The choroidal epithelial cells in continuous darkness contain larger mitochondria, larger Golgi vacuoles and more dilated rough endoplasmic reticulum than those in continuous light. From this finding, it seems likely that the choroidal epithelial cells in continuous darkness show more active in function than those in continuous light.
