Genioplasty using a cortical plate of the mandibular mental bone in surgical orthodontics. Report of 31 cases

It is often necessary to perform genioplasty in the same time of the surgical orthodontics. From Feb. 1985 to Feb. 1987, 31 cases of genioplaties were accomplished by using of cortical plate of mental mandibular bone. The ages of patients were ranged from 17-37 years old. The results of operations were satisfied.     

OXYGEN FREE RADICAL IN HUMAN OSTEOARTHRITIS

The xanthine oxidase catalysed release of superoxide free radicals (O2-) from endogenous hypoxanthine was determined in homogenates of synovium obtained from three groups of patients, those undergoing primary or revision total hip replacement (THR) for osteoarthritis and those undergoing arthroscopy of the knee for semilunar disc injuries. The concentrations of hypoxanthine in homogenates obtained during THR were found to be significantly higher than those in the group with semilunar disc injuries. The results suggest that there is a greater predisposition to free radical release and tissue damage in osteoarthritis.     

透明质酸酶对大鼠双光气中毒性肺水肿治疗的初步观察

本实验初步现察了HA对双光气中毒性肺水肿早期的治疗作用。结果提示,早期应用HA能显著延长动物存活时间,而治疗组与对照组动物在肺体指数、肺湿干重量比及肺含水量等项指标则未见显著差别。     

急性输液反应的影响因素及防治措施

目的 对临床发生的急性输液反应进行分析，找出发生的原因，探讨预防措施。方法对201885例次输液治疗中的52例次输液反应资料进行分析。结果 经分析，属药物因素27例（52％），属操作因素11例（21％），属病人因素11例（21％），属输液器具因素3例（6％）。结论 把好药品和操作关，改善操作环境，严格操作规程是减少输液反应的关键。
