    摘要: A water-soluble cellulose derivative which is obtained by subjecting a water-soluble cellulose to graft polymerization with 2-methacryloyloxyethyl phosphorylcholine and has a structural unit of the following formula (I): ##STR1## wherein n is an integer of 1-100, as well as a biocompatible material containing the water-soluble cellulose derivative as an effective component thereof. The water-soluble cellulose derivative having such specific structural unit is furnished with both of biocompatibility and affinity to cellulose and is thus utilizable as a biocompatible material, for example for hemocatharsis.

    摘要: The invention relates to a method for modulating the sedimentation rate of piscicultural dry pellets and to piscicultural dry pellets with a controlled sedimentation rate. The invention is characterized in that a defined surfactant is added to a piscicultural dry pellet material. In accordance with the invention, it is easy to modulate the floatation property or sedimentation rate of piscicultural dry pellets which has heretofore been difficult to control.
