文题释义:

空骨陷窝:骨陷窝是指骨细胞所在的腔隙,在骨组织中一般骨细胞被包绕在骨小梁中,其所在的腔隙即称为骨陷窝。空骨陷窝指缺少骨细胞的骨陷窝。
免疫组织化学:是抗原抗体反应的基本原理,使化学反应标记抗体的显色剂显色以确定组织细胞内抗原从而对其进行定位、定性、定量研究,称之为免疫组织化学技术(immunohistochemistry)或免疫细胞化学技术(immunocytochemistry)。
摘要
背景
:门冬酰胺酶能抑制血管生成及影响局部血运,对血管内皮细胞造成伤害,从而影响股骨头局部血运。
目的:对比观察门冬酰胺酶对地塞米松诱导缺血性股骨头坏死的影响。
方法:Balb/c雄性小鼠由大连医科大学实验动物中心提供,实验方案经大连大学附属中山医院动物实验伦理委员会批准。Balb/c雄性小鼠60只随机分为4组:①门冬酰胺酶+地塞米松组(n=15):小鼠饮水中放入地塞米松2 mg/L,实验一开始该组小鼠腹腔注射门冬酰胺酶(1 200 U/kg);②门冬酰胺酶组(n=15):门冬酰胺酶用量、用法同门冬酰胺酶+地塞米松组;③地塞米松组(n=15),小鼠饮水中放入地塞米松2 mg/L;④对照组(n=15):饲料和饮水中不放任何药物。8周后麻醉下处死小鼠,观察小鼠体质量、凝血因子指标、股骨头组织苏木精-伊红染色及免疫组织化学染色结果。
结果与结论:①门冬酰胺酶+地塞米松组小鼠体质量增长明显弱于其他3组;②门冬酰胺酶+地塞米松组小鼠凝血因子Ⅲ和凝血因子Ⅴ明显高于其他3组(P < 0.05或P < 0.01);③与其他3组比较,门冬酰胺酶+地塞米松组小鼠股骨头空骨陷窝率更高(P < 0.05),骨小梁占有率更小(P < 0.05),骨坏死程度更加明显;④免疫组织化学门冬酰胺酶+地塞米松组骨保护素积分吸光度值明显大于其他3组(P < 0.05或P < 0.01);⑤结果说明,门冬酰胺酶能够显著促进小鼠缺血性股骨头坏死。

Abstract:

BACKGROUND: Asparaginase can inhibit angiogenesis and affect blood supply, and make damage to the vascular endothelial cells, thereby affecting the local blood supply of femoral head.
OBJECTIVE: To investigate the effect of asparaginase on the avascular necrosis of femoral head induced by dexamethasone.
METHODS: Balb/c male mice were provided by Laboratory Animal Center of Dalian Medical University, and the study was approved by the Experimental Ethics Committee of Affiliated Zhongshan Hospital of Dalian University. Sixty male Balb/c mice were randomly divided into four groups: asparaginase + dexamethasone group (n=15, 2 mg/L dexamethasone in the water, and intraperitoneal injection of 1 200 U/kg asparaginase), asparaginase group (n=15, intraperitoneal injection of 1 200 U/kg asparaginase), dexamethasone group (n=15, 2 mg/L dexamethasone in the water), and control group (n=15, no intervention). All mice were killed after 8 weeks. The body mass, coagulation factors, hematoxylin-eosin staining and immunohistochemical staining of the femoral head were observed.
RESULTS AND CONCLUSION: (1) The body mass gain in the asparaginase + dexamethasone group was significantly lower than that in the other three groups. (2) The levels of coagulation factor III and V in the asparaginase + dexamethasone group were significantly higher than those in the other three groups (P < 0.05 or P < 0.01). (3) Compared with the other three groups, the empty bone lacunae rate was increased (P < 0.05), and trabecular fracture rate was decreased (P < 0.05), and the degree of osteonecrosis was more obvious in the asparaginase + dexamethasone group. (4) The absorbance value of osteoprotegerin in the asparaginase + dexamethasone group was significantly lower than that in the other three groups (P < 0.05 or P < 0.01). (5) These results indicate that asparaginase can promote avascular necrosis of femoral head in mice.

Key words: asparaginase, intravascular coagulation, vascular injury, avascular necrosis of the femoral head, mice
