Patent number: 8575368Abstract: This invention provides useful applications of cashew apple. This invention also provides a naturally occurring active ingredient having useful activities, such as alpha-amylase inhibitory activity, lipase inhibitory activity, and antibacterial activity against Propionibacterium acnes. The invention also provides a composition containing cashew apple-derived proanthocyanidin having excellent alpha-amylase inhibitory activity, lipase inhibitory activity, and antibacterial activity against Propionibacterium acnes, which is prepared by allowing a plant fiber-degrading enzyme (e.g., pectinase) to react with a cashew apple and concentrating the resultant with the use of an ultrafiltration membrane. Further, the invention provides a proanthocyanidin compound having a novel structure.Type: GrantFiled: June 25, 2009Date of Patent: November 5, 2013Assignee: Nichirei Biosciences, Inc.Inventor: Kenichi Nagamine

Publication number: 20120295279Abstract: Disclosed are a pretreatment solution for immunohistochemical staining, which elutes a paraffin-containing embedding medium from a glass slide with a tissue specimen embedded in the medium, and retrieves antigenicity of the tissue specimen, and which is usable three or more times, and a pretreatment solution concentrate for immunohistochemical staining which allows ready preparation of the pretreatment solution. The pretreatment solution for immunohistochemical staining contains an antigen retrieving agent, particular nonionic surfactants, and cyclodextrin or a derivative thereof, with the balance being not less than 80 mass % of water. The content of the antigen retrieval agent is such that the pH of the pretreatment solution is in a predetermined range, and the content of cyclodextrin or a derivative thereof is a particular amount.Type: ApplicationFiled: February 3, 2011Publication date: November 22, 2012Applicant: NICHIREI BIOSCIENCES INC.Inventor: Toshiyuki Kasamatsu
