Abstract

Nitric oxide (NO) has been reported to inhibit osteoclastic bone resorption. We examined the bone-sparing effect of NO after 6 weeks of administration into estrogen-deficient rats. 30 female Sprague-Dawley rats, 12 weeks of age, underwent ovariectomy (OVX), and 5 rats were sham-operated. OVX rats were assigned to six groups (n = 5/group) treated respectively with: vehicle; 17-beta-estradiol (E2); nitroglycerine (NG, NO donor); NG-nitro-L-arginine methyl ester (L-NAME, NO synthase inhibitor); combination of E2 + NG; and a combination of E2 + L-NAME. Prior to treatment and at the end of the treatment period, bone mineral density (BMD) of rats was measured by dual-energy X-ray absorptiometry (DXA) scanning. OVX animals had significantly lower BMD and femur weights in comparison to sham operated rats (p < 0.01), and this was completely prevented by the administration of E2 (p < 0.01). Administration of NG alone prevented OVX-induced bone loss (p < 0.05). The combination of E2 + NG did not further enhance the bone mass or femur weight, and the OVX-induced bone loss was not further aggravated by L-NAME. However, in the presence of L-NAME, E2 was totally ineffective in reversing the bone loss, suggesting that the protective effect of estrogens against bone loss may be mediated through NO. In summary, the results suggest that NO counteracts the bone loss associated with OVX.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
