The effects of brown rice, containing fourfold as much dietary fiber as polished rice, on the human fecal microflora were determined. Significantly increased numbers of Bifidobacterium adolescentis and Enterococcus faecalis were observed during the brown rice intake, whereas the total counts and the numbers of bacteroides, Eubacterium aerofaciens, and Escherichia coli during the intake were lower than those before and after the intake. Lower numbers of clostridia and low incidences of Clostridium paraputrificum and C. perfringens were observed during the brown rice intake.

Effects of capsaicin on stomach and small intestine in rats.

ラットにカプサイシン (とうがらしの辛味成分) を大量投与し, 胃および小腸におよぼす影響を観察して次のことが明らかとなった。1) カプサイシン (0.14mg) を1日1回, 3日間連続に胃内に注入したところ, 胃内容物が十二指腸へ移行するのが遅延した。2) カプサイシン (0.14mgあるいは1.4mg) を3日間連続投与後, さらに1日間飢餓状態にしたラットにおいては, 小腸内容物の乾燥重量, 窒素量, 脂質量が対照群よりも増加した。一方, カプサイシン投与後, 1日間飢餓にしたのち飼料を与えた場合には, 胃内容物の乾燥重量, 窒素量, 脂質量が対照群よりも多かった。3) カプサイシン (1.4mg) を3日間連続投与したラットの胃体部ならびに小腸粘膜を走査型電子顕微鏡で観察したところ, 胃体部の表層粘液細胞は破壊されて, 胃小窩の内面が露出した異常像がみられた。また, 小腸粘膜の絨毛も異常な像を示した。

Effect of Level of Protein Intake on Calcium, Phosphorus and Magnesium Balance of Children

Shiro Goto; Kazuharu Suzuki; Yusuke Kanke; Hideo Koishi; Takao Kitano

福祉施設で生活を共にしている男女児15名について, 食事中のたん白質レベルを変えたときのCa, PそしてMg出納の変化を観察した。その期間は昭和53年10月中の6日間である。1) 高たん白質レベルはCaの尿中排泄率を高める結果を得た。たん白質摂取量と体内Ca保留量との関係より推定すると26~31mg/kgのCa摂取ではたん白質レベルは2.9g/kg以下が望ましいように思われる。2) 高たん白質レベルはPの尿中排泄を高め, 体内保留を減少させる結果を得た。3) 高たん白質レベルはMgの尿中排泄増を招来した。
