Disclosed herein are a cocoon-based, vascular patch and a method for manufacturing the same. The cocoon-based, vascular patch is manufactured by dividing a cocoon into two or more fragments in a predetermined form, the cocoon having a shell having a predetermined thickness. The cocoon-based vascular patch can be relatively simply manufactured in a more cost efficient manner than conventional vascular patches, and has excellent cell growth potential and biocompatibility.

Disclosed herein are a cocoon-based, dental barrier membrane for guided bone regeneration and a method for manufacturing the same. The cocoon-based, dental barrier membrane is manufactured by dividing a cocoon into two or more fragments in a predetermined form, the cocoon having a shell having a first thickness. The dental barrier membrane is biocompatible, has excellent tensile strength and porosity, and promotes osteogenesis in a bone defect.

Disclosed is a method for the purification of bee venom on a mass scale. It comprises dissolving crude bee venom in a solvent to form a bee venom solution; applying an adsorbent to the bee venom solution to form a mixture; and removing the adsorbent through filtration to afford a pure bee venom solution. By the method of the present invention, crude bee venom collected from bee farms can be purified to a purity of 99% or higher on a mass scale, without inducing a change in the composition thereof, and thus the purified bee venom can be used as a material for medicines, cosmetics and foods.

Provided is an artificial eardrum using silk protein and a method of fabricating the same. The artificial eardrum is fabricated in the form of a silk membrane by desalinating and drying silk protein (or silk fibroin) or a silk protein complex solution obtained after removal of sericin from a silkworm cocoon or silk fiber. Thus, regeneration of an eardrum perforated due to disease or a sudden accident is stimulated, a boundary of the regenerated eardrum is clean and biocompatibility and transparency are increased. In addition, the artificial eardrum may be fabricated using the silk protein or silk protein complex solution obtained from a silkworm cocoon alone or mixed with collagen, alginic acid, PEG or pluronic 127.
