| pubmed-article:3455628 | pubmed:abstractText | To determine whether the nonsteroidal antiestrogen tamoxifen behaves as either an agonist or antagonist of estrogen on bone, the effects of ovariectomy, 17 beta-estradiol, and tamoxifen were compared on radial growth at the tibial diaphysis in young adult female rats. Ovariectomy and 17 beta-estradiol did not alter serum calcium, phosphate, or 25-hydroxyvitamin D. Ovariectomy increased serum 1,25-dihydroxyvitamin D in one experiment but not in the other. Tamoxifen increased the serum calcium and phosphate by itself and did not change serum 1,25-dihydroxyvitamin D in ovariectomized rats. Ovariectomy produced significant increases in medullary area, periosteal bone formation rate, and periosteal bone apposition rate compared to values in sham-operated animals and did not change endosteal bone formation rate. The increase in medullary area resulted from an increase in osteoclast number and resorbing surface length. Although endosteal forming surface length decreased, this was compensated for by an increase in the apposition rate. 17 beta-estradiol and tamoxifen each prevented the increases in bone formation rate and medullary area in ovariectomized rats. Tamoxifen reduced the length of the resorbing surface and osteoclast number to values observed in sham-operated animals. The findings demonstrate that in the rat, tamoxifen acts as an estrogen agonist by preventing the skeletal alterations that result from ovarian hormone deficiency. | lld:pubmed |
