Studies on the Tolerating Mechanism for Sulfide in Urechis unicinctus ( Echiura : Urechidae) -Cytological Observation o
This study on the cytological changes of the body wall, aspiratory intestine and crissalbursa in Urechis unicinctus by light microscope (LM) and transmission electron microscope (TEM)showed that the difference between the body wall and the natural environment rich in H2 S was notobvious; that the wall color of the aspiratory intestine in H2 S rich environment changed from normalsemitransparency to dark brown; that its epithelia were disassembled and the electron density of itscytoplasm matrix was lower; and that in H2 S rich enviromnent many basophilic granules occurred inthe epithelia of the crissal bursa. Granules with single membrane and myelinefingure were foundwith TEM.
