| 摘 要： | This study on the cytological changes of the body wall ,aspiratory intestine and crissal bursa in Urechis unicincuts by light microscope(LM) and transmission electron microscope(TEM) showed that the difference between the body wall and the natural environment rich in H2S was not obvious,that the wall color of the aspiratory intestine in H2S rich environment changed from normal semitransparency to dark brown.that its epithelia were disassembled and the electron density of its cytoplasm matrix was lower;and that in H2S rich environment many basoplhilic granules occurred in the epithelia of the crissal bursa.Granules with single membrane and myelinefingure were found with TEM.

| Abstract: | This study on the cytological changes of the body wall, aspiratory intestine and crissal bursa inUrechis unicinctus by light microscope (LM) and transmission electron microscope (TEM) showed that the difference between the body wall and
the natural environment rich in H2S was not obvious; that the wall color of the aspiratory intestine in H2S rich environment changed from normal semitransparency to dark brown; that its epithelia were disassembled and the electron
density of its cytoplasm matrix was lower; and that in H2S rich environment many basophilic granules occurred in the epithelia of the crissal bursa. Granules with single membrane
and myelinefingure were found with TEM.
This research was funded by the higher school key teacher project, China (No. GG-707-10423-2028). |
