The in vivo accumulation of neutral red, methylene blue and acriflavine in the body wall, midgut epithelium and chloragosomes of Lumbricus terrestris L. and Octolasium transpadanum Rosa, and the discharge of these dyes by chloragosomes was investigated by spectrophotometry. Chloragosomes accumulated the largest amount of the ingested dyes. EM showed activation of chloragogen cells and increased chloragosome formation on the 1st days of dye intake. In dye-free environment, dye content of the chloragosomes decreased rapidly. These properties of the chloragogen cells indicate the role of these cells in the defense mechanism against the toxic effect of certain cationic xenobiotics ingested via the intestinal tract.
