Culture of bone marrow hematopoietic stem ( progenitor) cell in vitro and its application in multiple sclerosis patients 球细脑脑白质营养不良多发性硬化患者骨髓造血干(祖)细胞体外集落培养及其意义
Resules of roentgenographic and CT: In 14 16 weeks, in group ⅰ, the coral was absorbed and most of the bone defects were closed completely; In the rest groups, part of each bone defect was remained except that in group ⅳ, cystic sclerosis was formed. 拍片及CT示:14~16周,Ⅰ组骨缺损大多完全闭合,珊瑚已吸收,其余各组骨缺损部分残留,Ⅳ组骨缺损囊壁硬化带形成。
In the later stages, the bone infarct was characterize by irregular sclerosis and tortuous calcification on X-ray and CT, and by low-signal on both T_1WI and T_2WI. 晚期X线及CT呈不规则、迂曲状骨质硬化,MRT1WI及T2WI均呈低信号。
On week 2 after operation, degeneration of cartilage was more severe with fibrosis of superficial cartilage and invasion into cartilage with subchondral bone, sclerosis of subchondral bone, reduction of proteoglycan resulting in mostly destaining of toluidine blue staining. 蛋白多糖分泌减少,表面的软骨组织甲苯胺蓝染色失染。第2周,软骨继续退变,表面软骨纤维化,软骨下骨硬化,部分侵入软骨层,蛋白多糖进一步丢失,甲苯胺蓝染色失染严重。
On radiography bone erosion was showed in 1 knee, subchondral sclerosis in 11 knees, joint space stricture in 16 knees, tibia movement in 8 knees. X线显示1个膝有骨破坏,11个膝伴骨硬化,16个膝关节间隙狭窄,8个膝胫骨移位。
The basic X ray manifestations were bone sclerosis and bone cavity occlusion, the characteristics were "filling with filling" in centrum and "homocentric circle" in ilium. X线表现以骨质硬化,髓腔闭塞为基本特征,椎体夹心征及髂骨同心圆征为其特征性表现。
The bone defect was filled by fiber scar tissue, without any bone tissue, and bone end sclerosis was demonstrated by gross, histological and X ray examination. 大体标本肉眼观察、放射学检查及病理组织学检查均显示骨缺损区无骨性连接,为纤维瘢痕组织填充,骨端硬化。
[ Objective] To establish a newly osteoarthritic model by increasing stiffness of subchondral bone with composite material PMMA/ HA to simulate subchondral bone sclerosis, from which assess the histopathologic changes to investigate the mechanism responsible for osteoarthritis. 【目的】制作PMMA/HA复合材料,通过增加软骨下骨刚度模拟软骨下骨硬化,诱发实验性骨关节炎的发生,以制作骨关节炎新的模型,探讨骨关节炎发病机制。
Diffusing long bone sclerosis with cortical bone destruction and cancellated bone erosion; 弥漫性长骨骨硬化,伴骨皮质穿凿样破坏及松质骨虫蚀样破坏;
The main X-ray change was bone sclerosis with unclear boundary. 平片改变主要呈云雾状骨质硬化,边界不清;
Different doses of fluoride intervention led to different results, mainly for the bone sclerosis, higher doses showed osteoporosis. 不同剂量氟干预导致结果不同,主要表现为骨硬化,高剂量表现出骨质疏松。
Clinical study found that many patients with osteoarthritis of the articular cartilage that occur before the morphological changes of subchondral bone sclerosis, such as X-ray changes. 临床研究发现,不少骨关节炎患者在关节软骨的形态学变化之前即出现软骨下骨硬化X线改变等。
Repeated micro-trauma of the articular cartilage can cause bone tissue under the micro-fractures and articular cartilage caused by the biomechanical and metabolic changes, bone sclerosis and osteophyte formation. 反复的关节微创伤可引起软骨下骨组织的微骨折,并引起关节软骨的生物力学和代谢的变化、骨硬化及骨赘形成。
Delayed fracture healing is a fracture after clinical treatment, surpasses the normal fracture healing time range still fails to form bone healing, X display fracture callus growth, mild decalcification, the fracture line is clear, but no bone sclerosis performance. 骨折延迟愈合是指骨折经过临床治疗,超过同类骨折正常愈合的时间范围仍未能形成骨性愈合,x线显示骨折端骨痂生长少,轻度脱钙,骨折线清晰,但无骨硬化表现。
