Patent number: 9233129Abstract: 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.Type: GrantFiled: July 2, 2014Date of Patent: January 12, 2016Assignee: Republic of Korea (Management: Rural Development Administration)Inventors: Sang Mi Han, Kwang Gill Lee, Kwan Kyu Park

Patent number: 8500808Abstract: 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.Type: GrantFiled: June 29, 2009Date of Patent: August 6, 2013Assignees: Republic of Korea represented by Rural Development Administration, Industry Academic Cooperation Foundation, Hallym UniversityInventors: Hae Yong Kweon, Kwang Gill Lee, Seok Woo Kang, Joo Hong Yeo, You Young Jo, Soon Ok Woo, Sang-Mi Han, Chan Hum Park, Jin Kim, Chun Hwoi Kim
