Abstract
Description
アカシア(Acacia mearnsii De Wild.)の樹皮を粉砕し、100℃の熱水で抽出した。得られた溶液をスプレードライヤーで噴霧乾燥し、熱水抽出物を得た。
(実験動物)
雌性BALB/cマウスを、コントロール群(n=8)、及び投与群(n=8)に分けた。22日間、コントロール群には普通飼料を経口投与し、投与群にはアカシア樹皮抽出物3%含有飼料を経口投与した。22日目に各群のマウスの糞を採取した。
なお、マウスは温度24±1℃、湿度55±5%の施設において飼育し、明暗条件は8:00点灯、20:00消灯とした。
1.DNAの抽出・調整方法
糞からの細菌DNAの抽出はQIAamp DNA stool mini kit (Qiagen, Inc)を用いて行った。抽出方法はQIAamp DNA stool mini kit付属のプロトコールに従った。得られた溶液を、微量分光光度計にて260nm及び280nmの吸光度を測定することで、純度の確認及びDNA濃度(ng/μL)の算出を行った。
各種プライマーを作成し、リアルタイムPCRにより、ビフィドバクテリウム属の菌、及びラクトバチルス属の菌を検出した。PCRプレートの各ウェルへSsoAdvanced Universal SYBR Green Supermix 5μL、目的遺伝子のforward primer(5pmol/μL) 0.6μL、reverse primer(5pmol/μL) 0.6μL、DNA溶液 2μL、RNase free water 2.8μLを加えた。PCR条件は、denaturation温度として95℃で30sec、annealing温度として58℃で30sec、elongation温度として72℃で60secとした。増幅過程の蛍光強度をCFX Connect Real-Time System(Bio-Rad Laboratories)によりモニタリングした。発現量は、16SrRNAを用いてノーマライズした。
結果を図1に示す。糞中のビフィドバクテリウム属の菌の量が、投与群では、コントロール群と比較して、約3倍に増加していた。また、糞中のラクトバチルス属の菌の量が、投与群では、コントロール群と比較して、約2倍に増加していた。
