Description
(1)所定量の多孔質シリカが付着する不織布0.1gを裁断して20mlチューブに投入
(2)チューブにリン酸緩衝液2ml、汗0.3mlを添加し、振盪、上清液をろ過
(3)ろ液を不織布/汗混合試験液とする。
2.ヒスタミン遊離抑制率
ヒスタミンは、不織布/汗混合試験液を準備した後、文献(Koro,O.et.al. J.Allergy Clin.Immunol.,Volume 103,Number4,April 1999,P663-670)記載の方法により遊離の定量化(遊離率の測定)を行う。ヒスタミン遊離抑制率は、不織布/汗混合試験液に血清懸濁液を混合させ、その上清と血球沈殿の混合液中のヒスタミン濃度と上清液中のヒスタミン濃度の割合である遊離率を算出することで、下記数1の式により、求められる。
