目的:通过测定微血管血流灌注来反映微血管的舒张功能,同时观察体外反搏治疗改善冠心病患者微血管舒张功能障碍的效果。方法:应用激光多普勒血流量计(LDF) ,测量58 个被观察者的前臂皮肤在反应性充血前后微血管血流灌注增加比值,评价血流介导的微血管舒张功能。结果:冠心病组、高胆固醇血症组及吸烟组微血管舒张功能明显低于对照组,比值分别为1.83±0.37、2.63±0.51、3.19 ±0.56 比3.56±0.36 ;P分别< 0.01,<0.01,< 0.05。冠心病组反搏治疗前后比,其微血管的舒张功能明显提高,比值为1.83±0.37 比2.54±0.43; P<0.01。结论:LDF可检测冠心病患者明显的微血管舒张功能障碍及高胆固醇血症者和吸烟者微血管功能的异常;体外反搏治疗可改善冠心病患者的微血管舒张功能。 相似文献

The stability of the monocyclic -lactam antibiotic aztreonam in portable pump reservoirs was studied during storage at temperatures of-20°C and +5°C and during drug delivery at 37°C. Three 100-ml drug reservoirs and three glass containers containing 60 mg/ml aztreonam were stored at-20°C and 2-ml samples were analysed in the freshly prepared solution and after thawing at days 7, 21, 28, 70 and after 6 months of storage. A separate triplicate batch of 100-ml prefilled drug reservoirs and glass containers containing a similar aztreonam concentration (60 mg/ml) were refrigerated and tested immediately after preparation and daily for 8 days and after 70 days. Solutions of aztreonam in duplicate freshly prepared reservoirs were tested for stability when the solution was pumped at 37°C over a 24-h period. All solutions were inspected for visual changes and tested for pH. Drug concentration was analysed by high-performance liquid chromatography. No colour changes or pH differences were observed in any of the solutions in the reservoirs or containers. No statistically significant decrease in aztreonam concentration could be detected after 6 months of storage at-20°C. Aztreonam was stable at 5°C for at least 8 days. A 24-h pumping period at 37°C showed a 3.6% decrease in aztreonam concentration. Aztreonam at a concentration of 60 mg/ml in a pump reservoir is sufficiently stable to be used in home intravenous antibiotic treatment programmes. 相似文献

To evaluate the steno-occlusive changes in the external carotid system in moyamoya disease, cerebral angiograms of 39 moyamoya patients were retrospectively reviewed. There were 26 females and 13 males, age ranged from 4 to 62 years with a mean of 26 years. Initial symptoms were ischaemia in 27 patients, haemorrhage in 9, and none in 3. Stenosis, occlusion, and dilatation in the external carotid system were analysed angiographically. No stenosis or occlusion of the superficial temporal artery, middle meningeal artery, or occipital artery was observed in either preoperative or postoperative follow-up angiograms in any patients. Steno-occlusive changes do not occur in the external carotid system, but are confined in the internal carotid system in moyamoya disease. 相似文献

To determine the postoperative incidence, extent and recurrence rate of exostoses of the external auditory canal in a cohort of patients involved in different water sports. A cross‐sectional study of 31 patients (46 ears), with exostoses treated by surgery in the Royal Cornwall Hospital between 1980 and 1999. A questionnaire was used to obtain information about the type of water exposure pre‐ and postoperatively. The extent of recurrent stenosis was assessed. The mean postoperative time interval was 10 years (sd = 4.5 years). The degree of stenosis was assessed as: minimal (<30%) in 42.6%, moderate (30–60%) in 31% and severe (>60%) in 25% of ears. The Cox regression model was used to identify factors associated with a reduction in the recurrence rate of stenosis. The use of ear plugs was highly significant (P = 0.015), as was the age of the patient at the time of operation (P = 0.004), i.e. the older the patient, the faster recurrent disease developed. There was no evidence to show that either the type or seasonal pattern of water sport activity influenced recurrence of the disease postoperatively, although preoperatively, the stenosis was more marked in association with surfing and sailing. Exostoses developed faster preoperatively in those who were in the water all year round rather than just the summer months. Of five patients who stopped water sport activity completely after surgery, four of them developed significant recurrent exostoses (>50% stenosis). 相似文献
