Two hydroxyl containing dithiocarbamates, sodium N-methyl-D-glucamine dithiocarbamate (NaG) and sodium dihydroxyethyl dithiocarbamate (NaY) have been examined as agents for the control of the renal dysfunction in rats given cisplatin. Of these, NaG was found to be the more effective in controlling such renal dysfunction when administered at 1 and 3 h after 5 mg cisplatin kg-1, i.p. Renal function was examined 5 days after the administration of cisplatin by measurement of serum and urinary levels of creatinine and urea, creatinine clearance, serum and urinary levels of Na+, K+, Mg2+, Ca2+, as well as the concentrations of these ions in the renal medulla and cortex. Treatment of rats given cisplatin with NaG at 1 and 3 h post cisplatin resulted in indices of renal function which were not significantly different from those of animals which had received no cisplatin. The sole difference was found to be a slight increase in renal cortical Na+ concentration. 相似文献

Eighty four out of 2151 militancy trauma patients sustained severe maxillofacial injury from Jan 1990 to March 1993. The resuscitation, stabilisation and intensive care of these patients was based on management priorities of primary resuscitation, care of airway, management of haemodynamics, oxygenation and monitoring. Anaesthesia was administered in a situation when the airway was likely to be compromised and the patients were critically sick. Initial ventilation and oxygenation was the most difficult and could be achieved with satisfactory seal around the face mask by applying water-soaked guaze pieces around the mouth and nose to “fill-in” the defects. Tracheal intubation could be accomplished with intravenous sedation by an experienced anaesthesiologist. Dental occlusion and wiring necessiated the placement of nasotracheal tube for 48-72 hours after surgery.KEY WORDS: Trauma, Maxillofacial injury, Trauma anesthesia, Anaesthesia and critical care 相似文献

In experiments on frog urinary bladder the mechanisms behind the gradual development of a hydroosmotic reaction to antidiuretic hormone (ADH) were investigated. It was suggested that the velocity of hydroosmotic reaction may be limited by (a) formation and insertion of particle aggregates into the apical membrane or (b) by velocity of cAMP formation. The urinary bladders were exposed to 23 nM ADH for different times (from 1 to 20 min) and water flow was measured over a period of 40 min. It was found that the value of the full hydroosmotic response increased progressively with the time of exposure to the hormone; however, the enhancement of water flow was equal during each time interval before reaching the reaction maximum. A direct correlation between the value of ADH-stimulated water flow, cAMP content in bladder tissue and frequency of particle aggregates in the granular cell apical membrane was observed. The content of cAMP in ADH-treated bladders was higher by 80% in the absence than in the presence of an osmotic gradient. Pretreatment of urinary bladders with 50 M cyclic nucleotide phosphodiesterase inhibitor, 3-isobutyl-1-methylxanthine, significantly accelerated the development of the hydroosmotic reaction and increased the magnitude of water flow in comparison with the effect of ADH only. No changes in cyclic AMP phosphodiesterase activity were found in the urinary bladder homogenates under the action of ADH, so it seems likely that accumulation of cAMP depends only on the increase of adenylate cyclase activity. The data obtained allow one to conclude that the gradual hydroosmotic response to ADH depends on the accumulation of cAMP, which may be considered as the main limiting factor of the velocity of the hydroosmotic reaction. 相似文献

目的探讨显微镜辅助下颈前路椎间盘切除植骨融合术(anterior cervical discectomy with fusion,ACDF)治疗多节段脊髓型颈椎病的疗效。方法回顾性分析2011年1月~2012年8月本院行颈前路手术治疗的60例脊髓型颈椎病患者的临床资料,根据手术方式分为常规ACDF组(A组,30例)和显微镜辅助ACDF组(B组,30例)。比较2组的手术时间、术中出血量、住院天数及并发症,以日本骨科学会(Japanese Orthopaedic Association,JOA)评分(17分法)及其改善率评价术后神经功能改善情况。结果 A组手术时间为(132.5±8.9)min,B组为(137.0±9.1)min,差异无统计学意义(P0.05)。A组术中出血量为(113.6±8.0)m L,B组为(93.7±5.3)m L,差异有统计学意义(P0.01)。A组住院(7.37±1.73)d,B组(6.63±1.13)d,差异无统计学意义(P0.05)。A组术前JOA评分为6.60±1.21,术后12个月为13.83±0.91,改善率为(69.72±7.66)%;B组术前JOA评分为6.87±1.46,术后12个月为14.23±1.17,改善率为(72.51±11.26)%。A组和B组改善率差异有统计学意义(P0.05)。结论显微镜辅助ACDF和常规ACDF是治疗多节段脊髓型颈椎病有效的方法,但显微镜辅助ACDF可减少术中出血量,是治疗多节段脊髓型颈椎病优先选择的手术方案。 相似文献
