By means of the electron microscopy, the author has observed and studied continuously the changes of the nuclear membrane ultra-microstructure of the posterior silk gland cells during the fifth instar of larval Bombyx mori.

By means of electron microscopy, the ultrafarm of the rough endoplasmic reticulum membrane system of the posterior silkgland cells of the fifth instar larvae in Bombyx mori was investigeted continually.

0mg/kg) by 40-days routine immunity method; ELISA method was used to examine the titration (valence) of anti-alginate serum; Five groups (group A contrast, group B: BSA, group C: alginate, group D: anti-alginate serum, group E: alginate +anti-alginate serum) were examined by MTT method at four times (1h, 6h,12h and 24h);In the meanwhile, The gr.

Five groups(group A: contrast,group B: BSA,group C: alginate,group D: anti-alginate serum,group E: alginate +anti-alginate serum) were examined by MTT method at four time points(1,6,12 and 24 h).
