Abstract :カルシウム欠乏食を2週間投与した7週齢の雌ラットは,骨の破断力が低下し,X線写真の透過度が有意に低下し,骨が折れやすい状態の骨粗鬆症になった.運動の負荷,ナトリウム付加食,カリウム付加食は,これらの低下や増加を軽減し,骨粗鬆症を阻害傾向がみられた.ナトリウム付加食やカリウム付加食では,血中のエストロゲンが増加し,尿中のデオキシピリジノリンが低下した.
Seven-week old female Wistar rats fed calcium deficient food for 2 weeks succumbed to osteoporosis with significant decreases in bone fracture energy and high level of relative X-ray density. Lording of running, sodium supplying food intake and potassium supplying food intake were appeared to inhibit osteoporosis due to rise the increase of bone fracture energy and reduce the high level of relative X-ray density. Sodium supplying food intake and potassium supplying Ca^<2+> deficienl food intake brought increase of serum estradiol level by reduction of urinary deoxypiridinoline.
