摘要： A biodegradable biopolymer material consists of silk fibroin from domesticated silkworm; silk fibroin from wild silkworm; a composite material comprising silk fibroin from domesticated silkworm and silk fibroin from wild silkworm; or a composite material comprising either silk fibroin from domesticated silkworm or silk fibroin from wild silkworm and at least one secondary substance selected from the group consisting of cellulose, chitin, chitosan, chitosan derivatives, keratin from wool and polyvinyl alcohol. The material may be prepared by, for instance, casting an aqueous solution of domesticated silkworm silk fibroin on the surface of a substrate and then cast drying the applied solution. The biodegradable biopolymer material is effectively used as, for instance, a metal ion-adsorbing material, a sustained release substrate for a useful substance such as a medicine, a biological cell-growth substrate and a biodegradable water-absorbing material.

摘要： The present invention relates to chitin beads having a uniform and fine particle size and comprising microsporidian spores whose principal cell wall substance is chitin; chitosan beads comprising N-deacetylated chitin and having a uniform fine particle size; methods for preparing these beads; carriers comprising these beads; and a method for preparing microsporidian spores.Microsporidian spores are proliferated in insect's bodies or cultured cells to obtain chitin beads having the uniform and fine particle size and whose cell wall substance is mainly composed of chitin. The chitin as the major cell wall substance is subjected to N-deacetylation to give chitosan beads. When the insect is a larva of domesticated silkworm, microsporidian spores are proliferated by orally or percutaneously inoculating the spores into the 2nd instar domesticated silkworm larvae in a concentration of 5.times.10.sup.2 to 5.times.10.sup.8 spores/ml, then the proliferated microsporidian spores are isolated from the bodies of the grown 5th instar domesticated silkworm larvae, followed by purifying the resulting spores to give chitin beads having the uniform and fine particle size and chitosan beads can be obtained from the chitin beads in the same manner used above. These beads are used as carriers for the immobilization or encapsulation of a variety of substances such as an antibiotic and a microorganism.

摘要： The present invention provides a gene Any-RF derived from an insect, having dormancy-control activity and biological cell-control function; a dormancy-control substance and a method for preparing the same; as well as a biological cell-control agent, which comprises, as an effective component, a physiologically active substance having a biological cell-control function and which never causes any antigen-antibody reaction in the living body.The gene encodes for a protein having an amino acid sequence specified as Sequence No. 1 in SEQUENCE LISTING: Asp-Ile-Leu-Arg-Gly, whose C-terminal is amidated and having a molecular weight of 570.959. The physiologically active substance comprising such a gene is a peptide, which can be isolated and purified by adding an acid-methanol aqueous solution to Antheraea yamamai, triturating the resulting mixture, centrifuging the same and then treating the resulting supernatant in an HPLC system. The peptide permits the control of the dormancy of insects and is also useful as a biological cell-control agent, which comprises, as an effective component, such a peptide.
