查询词典 bone

Treatment of spinal tuberculosis1methods between february 1998 and august 2000 , 12 patients with spinal tuberculosis were operated with anterior vertebrectomy , bone grafting and plating1 evaluation including bone fusionrate , correction of deformity and status of spinal lesion was carried out1results in an average of ten months ,spinal tuberculosis was completely cured and solid bone fusion had taken place in all 12 patients1 the time for bone fusion averaged 518 months and the average angle of correction of kyphosis was 16°1conclusions anterior plating following vertebrectomy and bone grafting offers a complete removal of lesion and decompression of the spinal canal as well as reconstruction of spinal stability1 early rehabilitation and an increased curative rate can be expected through this procedure1

目的 探讨经脊柱前路结核病灶清除的同时植骨内固定的可行性和必要性，以及对脊柱结核的治疗效果。方法1998 年2月~2000 年8 月采用脊柱前路病椎切除加植骨，并采用orion或z-plate 钢板进行椎体固定。共治疗12 例脊柱结核，观察植骨融合及矫正畸形情况和结核病灶愈合情况。结果经平均10 个月的随访，12 例患者脊柱结核均治愈，植骨与受骨区全部骨性融合，融合时间平均为518 个月，后凸矫正角度平均16°。全组病例切口均一期愈合。无手术并发症。结论本方法可经脊柱前路作较彻底的病灶清除，并较好地进行脊柱矫形和椎管减压，完成脊柱稳定性重建，有利于患者早期离床活动和脊柱结核治愈率的提高。

Allogeneic and syngeneic fresh bone, autolyzed antigen-extracted bone, bone matrix gelatin, demineralized bone matrix were implanted into the muscle pouch of mice, at different times after implantation, the immunological, histological and alkaline phosphatase assay were conducted. The results revealed that all four kinds of allogeneic implants activated specific cellular and humoral immune responses, most notably in fresh bone group, the AAA, BMG and DBM inhibited the proliferation of the lymphocytes in vitro and BMG had the most powerful inhibiting action, allogeneic AAA, BMG and DBM might induce heterotopic osteogenesis in vivo, however, there were obvious difference in ALP and histomorphometry between allografts and isografts.
