| Effects of Chloroquine on the Photosensory Membrane Turnover and the Ultrastructure of Lysosome-Related Bodies of the Crayfish Photoreceptor  | | | | Abstract
| The effect o f chloroquine in combination with bright light on the ultrastructure o f crayfish (Orconectes limosus R.) photoreceptors was investigated in vivo. Chloroquine had several ef fects upon the crayfish retina. Multivesicular bodies (M VB) that are involved in lysosom al degradation o f photosensory membrane were altered in ultrastructure. M VB frequently con tained smaller M VB in a state o f more advanced membrane degradation. A dditionally screen ing pigment-like granules appeared in MVB. MVB accumulated in and filled the retinular cell cytoplasm just proximal or distal to the basement membrane which indicated inhibition o f photosensory membrane degradation. Under chloroquine treatment rhabdom degradation appeared to be inhibited, as rhabdom diameter was less reduced under these conditions. A lso chloroquine caused accumulation o f screening pigment granules in glial cells within the lamina ganglionaris. | | | |
