文题释义:
酒精性股骨头坏死动物模型:
Solomon等以随意饮酒模式让大鼠饮酒40周,出现骨质疏松、股骨头坏死表现;王义生等采用灌胃法给予家兔烈性酒(含体积分数45%乙醇)10 mL/(kg•d)共6个月;齐振熙等采用高乙醇度白酒(含乙醇56%)给成年大鼠灌胃,剂量分别为8 mL/(kg•d)和6 mL/(kg•d);范猛等通过局部注射无水乙醇成功建立鸸鹋股骨头坏死模型。局部注射无水乙醇短期内即可制作股骨头坏死模型,且部分研究造模4周股骨头坏死周围出现修复反应,但这种方法与人类股骨头坏死发病过程大相径庭。
股骨头坏死标准:病理切片下股骨头骨小梁坏死紊乱和骨小梁中空骨陷窝百分百增高。

 

摘要
背景:
长期大量饮酒与股骨头坏死的关系早已明确,但乙醇引起股骨头坏死的病理机制目前并未完全阐明。
目的:制作酒精性股骨头缺血坏死大鼠模型,探讨其发病机制。
方法:将80只Wistar大鼠随机分为实验组与对照组,每组40只,实验组灌胃给予烈性白酒10 mL/kg,1次/d,连续6个月;对照组灌胃给予生理盐水10 mL/kg,1次/d,连续6个月。每个月随机取6只大鼠双侧股骨头,进行组织形态学观察。
结果与结论:①骨坏死:实验组3个月时骨小梁变细,排列紊乱,空骨陷窝数开始增加,6个月时出现典型的骨坏死,空缺骨陷窝明显增加;对照组骨小梁完整,排列整齐,骨陷窝中骨细胞清晰可见,细胞形态正常;②血管损伤:实验组3个月时微动脉内膜增生,部分血管内皮下弹力纤维减少,弹性纤维及中层平滑肌断裂、增生,6个月时上述表现更加明显;对照组微动脉膜未见增厚,血管壁正常;③微血栓形成:实验组3个月时微血栓数量明显增加,6个月时变化更加显著;对照组微血栓数量无明显变化。④结果表明:长期摄入乙醇可导致大鼠股骨头内微血管内皮损伤,局部微循环供血异常,诱发股骨头缺血性坏死,且坏死程度与乙醇累积摄入量相关。

Abstract:

BACKGROUND: The relationship between long-term heavy drinking and alcohol-induced necrosis of the femoral head has long been clear, but the pathogenesis of alcohol-induced necrosis of the femoral head is currently not fully understood.
OBJECTIVE: To establish a rat model of alcohol-induced avascular necrosis of femoral head and to study its pathogenesis.
METHODS: Eighty Wistar rats were randomly divided into experimental and control groups (40 rats per group). Rats in the experimental group were intragastrically administered strong wine 10 mL/kg, once a day, for 6 consecutive days. Rats in the control group were given physiological saline 10 mL/kg, once a day, for 6 consecutive days. Bilateral femoral heads were randomly collected from six rats every month for histomorphological observation.
RESULTS AND CONCLUSION: (1) Osteonecrosis: in the experimental group, at 3 months, trabecular bone became thin, arranged disorderly, and the number of empty lacuna began to increase. At 6 months, typical osteonecrosis appeared, and vacant lacunaes increased significantly. In the control group, trabecular bone was complete and neatly arranged. Osteocytes were visible in bone lacuna, and normal morphology of cells was seen. (2) Injury of blood vessels: in the experimental group, at 3 months, micro-intimal hyperplasia was observed. Elastic fibers of partial vascular endothelium were reduced. Elastic fiber and middle-layer smooth muscle breakage and proliferation were found. At 6 months, above manifestations were more remarkable. In the control group, arteriole film was not thickened, and vessel wall was normal. (3) Formation of microthrombus, in the experimental group, the number of microthrombus was increased at 3 months, and became significant at 6 months. In the control group, the number of microthrombus was not altered. (4) Results indicated that chronic alcohol intake can lead to microvascular endothelial injury in the rat femoral head. Abnormal blood microcirculation was detected in local region, and resulted in avascular necrosis of the femoral head. The degree of necrosis was associated with alcohol intake.
