[Phytoestrogens role in bone functional structure protection in the ovariectomized rat].

Effects of soy protein diet on bone formation and density were evaluated in ovariectomized rats as a model for postmenopausal women. Twenty-seven 9-month-old rats were assigned to 3 treatment groups for the 9-week study: sham-surgery (Sh, n = 9); ovariectomy (Ovx, n = 9); ovariectomy + soy diet (OvxS, n = 9). Rats had free access to an AIN-93 M diet or AIN-93 M diet with 7% soy protein concentration and water.
