自体骨髓移植治疗股骨头无菌性坏死

Objective To investigate the effectiveness and mechanism of transplantation of autol-ogous bone marrow in treating femoral head necrosis. Methods Sixty New Zealand rabbits were randomly divided into groups A,B,and C after establishment of the models of femoral head necrosis. The left femoral head served as the control one,and the right as the experimental group. The mitoxantrone (0.1 mg/kg) with the help of DSA was injected into the femoral head of group A. One ml autologous bone marrow was injected into the femoral head of group B. In group C,mitoxantrone (0. 1 mg/kg) was injected,and 72 h later,1 ml autologous bone marrow was injected. Four months later,all rabbits were killed,and the femoral heads were removed and observed histologically and electron microscopically. Results The number of necrotic osteoclasts in groups A and B showed no significant difference ( P > 0.05 ), ande in group C, the number of necrotic femoral heads at the left and fight sides was 40. 60±4.11 and 21.33±2.16 respec-tively ( P < 0.05 ). At the experimental side of group C, the structure of majority bone cells was clear and intact,and necrosis was occasionally seen. Conclusion At the cellular level, local chemotherapy and au-tologous hematopoietic stem cell transplantation had certain effectiveness for aseptic necrosis of the femoral head.     

糜蛋白酶治疗浆液性耳廓软骨膜炎

浆液性耳廓软骨膜炎（或称耳廓假性囊肿）主要病变为耳廓软骨和软骨膜之间有血清渗出。因局部血运不丰富。病程长，不易治愈，处理不当可转化为化脓性。因软骨膜提供软骨营养，当长期软骨膜病变严重影响到软骨的血液供应时，可引起软骨坏死，愈合后可造成耳廓畸形不良后果。     

口腔颌面部大块软组织缺损整复60例

对口腔颌面部大块软组织缺损的整复,自1965年Bakamjian报道应用胸三角皮瓣以来,有显著的进展;许多旧的方法渐废弃;而许多新的方法正在不断地涌现出来。我科从1980年1月至1985年共施行口腔颌面部大块软组织缺损的整复60例。取得了良好效果,现小结于后。     

应用胸锁乳突肌皮瓣一期修复唇颊腮颊组织洞穿缺损

本文介绍应用胸锁乳突肌皮瓣一期修复唇颊、腮颊组织洞穿性缺损四例,疗效满意,认为该瓣是修复面颊缺损的良好材料。应用解剖胸锁乳突肌血供丰富,枕动脉和耳后动脉的分支供肌肉的上部,中部来自甲状上动脉或直接发自颈外动脉的分支,下部     

急性软脑膜微循环障碍实验模型的研究

本文报道应用高分子右旋糖酐制成软脑膜微循环障碍的动物实验模型。软脑膜微循环障碍模型的标志;软脑膜微血管血流速度减慢,血液流态呈粒状流或絮状流,血细胞聚集。 将98只家兔分成甲、乙二组。甲组38只,静脉注射平均分子量为25万的高分子右旋糖酐,乙组60只,静脉注射平均分子量为49万的高分子右旋糖酐。实验结果发现,甲组38只家兔仅28只可复制成软脑膜微循环障碍的实验模型,模型复制成功率为73.6％;乙组60只家兔,59只可形成软脑膜微循环障碍实验模型,成功率为98.3％。本实验证明复制动物模型以49万分子量的高分子有旋糖酐为宜。 本实验模型可用于脑微循环障碍和改善脑微循环药物的研究工作。     

游离背阔肌皮瓣修复四肢肿瘤切除后创面

我院骨科组于1985年5～10月份为4例患下肢高分化低度恶性肿瘤的病人,在化疗的配合下施行肿瘤局部大块切除,吻合血管的背阔肌肌皮瓣移植修复创面等综合治疗,早期获得了满意的效果.4例病人中有2例患小腿软骨肉瘤,1例小腿脂肪肉瘤和1例髋部纤维肉瘤.背阔肌肌皮瓣较适用于修复软组织缺损大的创面,其大而扁平的肌肉部分几乎能完全覆盖缺损,外形亦常较满意.
