Description
ジャガイモ抽出物およびダイズトリプシンインヒビター(SBTI:Sigma Type II-S、Sigma社製)について、ラットの食欲抑制に関する効果を調べた。SBTIは、CCKの放出を増大し、その結果、摂食量を低下させることが報告されている(特許文献6)。
動物:SD系雄ラット、8週齢
飼料:AIN-93G(Reeves PG, Nielsen FH, Fahey GC Jr. AIN-93 purified diets for laboratory rodents: final report of the American Institute of Nutrition ad hoc writing committee on the reformulation of the AIN-76A rodent diet. J Nutr 123: 1939-51, 1993に基づき調製)
明暗周期(逆転):暗期10:00-22:00、明期22:00-10:00
12時間絶食後、暗期に入る直前に、水2mlに溶解した試験物質溶液をフィーディングチューブにてラットに経口(胃内)投与した。その後、AIN-93G飼料を再給餌した。給餌後1、2、3および6時間後に摂食量を測定した。試験物質として、ラット一個体あたり100mgのジャガイモ抽出物またはSBTIを用いた(水のみの投与を陰性コントロールとした)。
CCK分泌試験を以下の手順で行った。まず、マウス小腸由来のCCK産生細胞株STC−1(Dr. D. Hanahan, University of California, San Francisco, CAより提供)を、48ウェルプレート中で、10%ウシ胎児血清(FBS)を含むダルベッコ改変イーグル培地にて、37℃、5%CO2存在下、サブコンフルエントになるまで2〜3日間培養した。続いて、ウェルから培養培地を取り除き、Hepesバッファー(140mM NaCl、4.5mM KCl、20mM Hepes、1.2mM CaCl2、1.2mM MgCl2、10mM D-グルコース、0.1% ウシ血清アルブミン(BSA)、pH 7.4)にてウェル中で細胞を洗浄した後、Hepesバッファーに溶解した試験物質溶液100μlを各ウェルに添加し、37℃にて60分間インキュベートした。上清を回収し、800×gで4℃にて5分間、遠心分離して細胞を沈殿させ、その上清80μlを回収し、凍結保存した。凍結保存した上清を適宜解凍し、上清中のCCK濃度を、市販のELISAキット(Phoenix Pharmaceuticals Inc社製)を用いて定量した。上清中のCCK濃度(pM)をCCK産生細胞株STC−1からのCCK分泌量とした。
ジャガイモ抽出物(1、5、10および20mg/ml);
SBTI(Sigma Type II-S、Sigma社製;1、5、10および20mg/ml);および
ダイズβコングリシニンペプトン(BconP:ダイズβ−コングリシニンのペプシン加水分解物:β−コングリシニン(不二製油株式会社製)をリン酸溶液と混合してpH 1.85に調整し、ペプシン(SIGMA社製)を基質に対して0.5質量%で添加して37℃にて10分間反応させ、煮沸によりペプシンを失活させた後、遠心上清を中和、脱塩したもの);5mg/ml;陽性コントロールとして使用)。
試験物質として以下を用いたこと以外は、実施例2と同様の試験を行った。
ジャガイモ抽出物(5mg/ml);
ジャガイモ抽出物HP20非吸着画分(3.72mg/ml、ジャガイモ抽出物の5mg/ml分に相当;
ジャガイモ抽出物HP20吸着−20%エタノール溶出画分(0.59mg/ml、ジャガイモ抽出物の5mg/ml分に相当);および
ジャガイモ抽出物HP20吸着−80%エタノール溶出画分(0.23mg/ml、ジャガイモ抽出物の5mg/ml分に相当)。
試験物質として以下を用いたこと以外は、実施例2と同様の試験を行った。
ジャガイモ抽出物(5mg/ml)
ジャガイモ抽出物HP20吸着−80%エタノール溶出画分
0.225mg/ml(実施例3と同様にして調製した。ジャガイモ抽出物の5mg/ml分に相当)
0.113mg/ml(上記0.225mg/mlの調製物をHepesバッファーで2倍希釈した)
