Abstract

It has been demonstrated that histamine interferes with the recruitment, formation and activity of osteoclasts via H 1‐ and H 2‐receptors. Cimetidine is a H 2‐receptor antagonist used for treatment of gastric ulcers that seems to prevent bone resorption. In this study, a possible cimetidine interference was investigated in the number of alveolar bone osteoclasts. The incidence of osteoclast apoptosis and immunoexpression of RANK L (receptor activator of nuclear factor κB ligand) was also evaluated. Adult male rats were treated with 100 mg kg−1 of cimetidine for 50 days (CimG); the sham group (SG) received saline. Maxillary fragments containing the first molars and alveolar bone were fixed, decalcified and embedded in paraffin. The sections were stained by H&E or submitted to tartrate‐resistant acid phosphatase (TRAP) method. TUNEL (terminal deoxynucleotidyl transferase‐mediated dUTP nick‐end labeling) method and immunohistochemical reactions for detecting caspase‐3 and RANKL were performed. The number of TRAP‐positive osteoclasts, the frequency of apoptotic osteoclasts and the numerical density of RANKL‐positive cells were obtained. Osteoclast death by apoptosis was confirmed by transmission electron microscopy (TEM). In CimG, TRAP‐positive osteoclasts with TUNEL‐positive nuclei and caspase‐3‐immunolabeled osteoclasts were found. A significant reduction in the number of TRAP‐positive osteoclasts and a high frequency of apoptotic osteoclasts were observed in CimG. Under TEM, detached osteoclasts from the bone surface showed typical features of apoptosis. Moreover, a significant reduction in the numerical density of RANKL‐positive cells was observed in CimG. The significant reduction in the number of osteoclasts may be due to cimetidine‐induced osteoclast apoptosis. However,RANKL immunoexpression reduction also suggests a possible interference of cimetidine treatment in the osteoclastogenesis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • RANKL is also produced by stromal cells, osteoblasts, and fibroblasts.

    “There is evidence that osteocytes act as the main source of RANKL to promote osteoclastogenesis [167, 168], although this factor has also been demonstrated to be produced by other cell types such as stromal cells [194], osteoblasts, and fibroblasts [88, 89].”

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.
