Abstract

Dexmedetomidine has been shown to exert protective and curative effects on various tissues and organs in different pathological processes. This study aimed to investigate the effect of dexmedetomidine on the regeneration process after making holes in the parietal bones of rabbits. Twenty-four male Oryctolagus cuniculus rabbits were allocated to three groups, and an 8-mm circular parietal critical-sized bone defect was induced in each animal. Group_C (control) received saline; Group_LD (low dose) was given dexmedetomidine 2.75 µg/kg; Group_HD (high dose), dexmedetomidine 5.5 µg/kg; all were administered intraperitoneally for 7 days. After 8 weeks the bones were examined by micro-computed tomography (micro-CT) and histomorphometry. The results indicated that regeneration was improved in both the dexmedetomidine-treated groups. The lower dose increased the bone volume ratio (BV/TV) more than the higher dose. Trabecular thickness, connectivity value, and connectivity density were also higher in Group_LD than in Group_HD. Significant intramembranous ossification was observed in the dexmedetomidine-treated groups, and active osteoblasts were seen at the margins of new bone trabeculae. We conclude that dexmedetomidine, especially at the lower dosage, increases osteoblastic activity and regeneration quality.

期刊介绍: Biotechnic & Histochemistry (formerly Stain technology) is the official publication of the Biological Stain Commission. The journal has been in continuous publication since 1926. Biotechnic & Histochemistry is an interdisciplinary journal that embraces all aspects of techniques for visualizing biological processes and entities in cells, tissues and organisms; papers that describe experimental work that employs such investigative methods are appropriate for publication as well. Papers concerning topics as diverse as applications of histochemistry, immunohistochemistry, in situ hybridization, cytochemical probes, autoradiography, light and electron microscopy, tissue culture, in vivo and in vitro studies, image analysis, cytogenetics, automation or computerization of investigative procedures and other investigative approaches are appropriate for publication regardless of their length. Letters to the Editor and review articles concerning topics of special and current interest also are welcome.
