吉林洮南草原蚊虫种群及防治效果研究

目的调查吉林洮南草原蚊虫种群，开展现场蚊虫防治试验研究。方法采用人诱、人帐诱收集蚊虫，以滞留喷洒和热烟雾法进行灭蚊试验。结果在吉林洮南草原采获蚊虫2属5种，其中背点伊蚊（60．0％）和刺扰伊蚊（37．8％）为优势种群。防治试验结果表明，试验后1h热烟雾法蚊虫密度下降率可达100％，但到24h则完全失效；滞留喷洒后1h蚊虫密度下降率为97％，48h仍能达70％，滞留喷洒具有一定的持效效果。结论该草原蚊虫优势种群为背点伊蚊和刺扰伊蚊，热烟雾和滞留喷洒法对蚊虫均具有快速杀灭作用。     

10％高氯热雾剂的研制与现场灭蚊蝇效果观察

目的探索高效氯氰菊酯作为热雾剂的科学配制与应用。方法参照有关国家标准试验方法，进行助溶剂、稳定剂等筛选试验。结果研制的10％高氯热雾剂闪点适中、粘度小、低毒、冷热贮稳定性好。按2．5～5．0mg ai／m^3现场应用对蚊、蝇灭效达95％以上。结论该热雾剂性能稳定、效果可靠、使用安全、经济有效。     

可调温医用超声雾化器的研制

医用超声雾化器常用于呼吸道疾病的治疗之中,属于普及型的医疗器械.但现有的医用超声雾化器存在一个不足之处,其治疗效果随气温的下降而下降,为解决这一问题,经改进制作可调温医用超声雾化器,并取得国家实用新型专利.     

超声雾化吸入预防甲状腺术后呼吸道症状的临床研究

目的探讨减轻甲状腺手术后病人呼吸道症状的有效方法。方法将200例病人随机分为观察组100例，对照组100例。对照组按甲状腺手术后常规护理；观察组除按甲状腺手术后常规护理外，术后6h给予第1次超声雾化吸入，2次／d，共3d。结果观察组术后痰阻感、咳嗽和吞咽痛等症状的出现率明显低于对照组，有极显著性差异（P均〈0．001）。观察组的舒适率97％（97／100）明显高于对照组的舒适率35％（35／100），有极显著性差异（Χ^2=85．6506，P〈0．001）。结论甲状腺手术后病人使用超声雾化吸入进行预防性的治疗，有效地减轻了病人的不适症状，促进了病人的康复。     

Mediators of Hypersensitivity and "Fog"-Induced Asthma

Seven asthmatic and five normal subjects inhaled increasing amounts of nebulized water ("fog"). Neutrophil chemotactic activity (NCA), histamine and FEV1 measurements were undertaken before and at time intervals after challenge. In asthmatics, the mean maximal reduction in FEV1 (+/- 1 SD) was 46.6% +/- 11.5; whereas, in normal subjects, the reductions were less than 20% of pre-challenge values after the inhalation of 33 ml of water. There were no significant differences in the pre-challenge values for NCA between the asthmatics and the normal controls. When the highest values for NCA during the 30 min after challenge in the asthmatics were compared with controls there was a significant increase (P less than 0.02). The percentage change in NCA was also significantly greater in the asthmatics compared with the controls at 10 min after challenge (P less than 0.05). Fog-induced NCA was shown to be associated with proteins with approximate molecular weight of 600,000 daltons (as assessed by gel filtration chromatography on Sephacryl-S400). There was an increase in plasma histamine in the asthmatics after challenge but this was not significantly greater than the controls. These findings support the view that mediators might be involved in fog-induced asthma, possibly as a result of mast cell degranulation by "osmotic shock".
