近年来,应用于卫生害虫防治的昆虫生长调节剂的文献大量出现。已研究与应用的昆虫生长调节剂的类型包括昆虫保幼激素及其类似物,几丁质合成抑制剂和其它可改变昆虫生长作用的化合物。在实验室与现场已对许多种化合物防治不同骚扰性与媒介昆虫的作用进行了评价,其中阿尔多息,敌灭灵与灭幼宝等具有较好的防治作用,已在许多国家被注册,并应用于卫生害虫及兽医害虫的防治。自从Mian与Mulla(1982)关于这些化合物的作用以及对环境的影响的文献综述发表以后,已有许多研究和进展。迄今,关于昆虫生长调节剂防治的害虫类群已从叮咬性与骚扰或污染性的几种双翅目昆虫扩大到蚤类、蝉螂、蚂蚁等。本文分析与总结了近十年来关于应用于卫生害虫防治的昆虫生长调节剂的研究概况,并重点放在剂型的评价,新的防治机理,抗性的产生与状况以及对环境中非靶生物的影响。引用的文献为1983年至1994年。 相似文献

The relationship between tropical calcific pancreatitis (TCP) and fibrocalculus pancreatic diabetes (FCPD) is still unclear. The clinical, biochemical and radiological data of age-matched TCP and FCPD subjects have been briefly discussed in the present review. Fibrocalculus pancreatic diabetes patients present with a significantly lower BMI compared with TCP patients. Analysis of the family history reveals that some kind of environmental factors seem to play a predominant role in the development of diabetes in FCPD patients, although these factors remain to be identified. Both TCP and FCPD patients predominantly come from a rural background. Fasting and 2 h blood glucose values as well as fructosamine levels in FCPD patients are approximately four-times higher than those of TCP patients. Measurements of early renal haemodynamic and microvascular changes (glomerular filtration rate, kidney size, microalbuminuria and microtransferrinuria) indicate an early renal involvement in FCPD patients. Tropical calcific pancreatitis subjects have approximately twice as high fasting C-peptide values compared with FCPD patients. Findings of single stranded DNA measurements suggest the involvement of oxidative damage in FCPD patients. Ketosis resistance is the most conspicuous clinical feature in the FCPD group and this relative absence of ketosis is probably due to a defect in the ketone body synthesis pathway and/or in the regulation of counterbalancing hormones. Endoscopic retrograde pancreatography findings of TCP and FCPD patients suggest that FCPD should not be considered only as a form of secondary diabetes consequent to generalized pancreatic damage in TCP. 相似文献

We describe the anaesthetic management of a patient with a rareform of muscular dystrophy (Facioscapulohumeral or LandouzyDejerinetype). Anaesthesia and controlled ventilation using alfentanil-nitrousoxide and atracurium was satisfactory. In this patient, sensitivityto atracurium was found to be similar to that of the normalpopulation, but more rapid recovery was observed. 相似文献

Defects of the nonhelical ear after skin cancer extirpation can be challenging. When other reconstructive options are not optimal, split-thickness grafting is an easy and effective technique for successful aesthetic and functional restoration of the ear. 相似文献

Although prostatic calculi are relatively common, the etiology of these stones is not clear. We report a case with multiple prostatic calculi causing urinary obstruction and a concomitant bladder stone. We treated these stones endoscopically. We found a lot of different sized stones endoscopically, some protruding into the urethra, some filling different cavities on the prostate. So these cavities suggest prostatic calculi may occur related to intraprostatic reflux in the congenital or acquired diverticulum of the prostatic tissue. In addition, the stone composition of the bladder and prostatic stones was the same. All of these results show that the origin of bladder and prostatic stones can be the same. This case also supports a theory of intraprostatic reflux and urine stasis. 相似文献

Effect of intraurethral Mitomycin-C on healing and fibrosis in rats with experimentally induced urethral stricture 总被引:3,自引:0,他引:3
ALI AYYILDIZ BARIS NUHOGLU BÜLENT GÜLERKAYA MUZAFFER ÇAYDERE HÜSEYIN ÜSTÜN CANKON GERMIYANOGLU DEMOKAN EROL 《International journal of urology》2004,11(12):1122-1126
BACKGROUND: In the pathogenesis of urethral stricture, fibrosis is associated with an excessive collagen increase. After the recognition that topical application of Mitomycin-C (MMC) inhibits fibroblast proliferation and is effective in preventing scar formation, many studies have been carried out on this subject outside the scope of urology. The aim of the present study is to observe the intraurethral impact of the employment of low doses of MMC on scar formation and fibrosis in experimental rat model. METHODS: Urethral injuries were made by internal urethrotomy knife. The study was carried out with 35 adult male Wistar albino rats. Five rats were allocated to the control group (group 1), 10 to a group that was administered 2 mg/L MMC (group 2) and 20 to a group that was administered 10 mg/L MMC (group 3). Mitomycin-C was administered to the injured urethra in the form of irrigation for 5 min. The rats were sacrificed 14 days later in order to evaluate chronic inflammation and fibrosis and their penises were histopathologically examined under light microscopy with hematoxilen eosin and trichrom stains. RESULTS: When group 2 was compared with control group, the differences in hemosiderin-laden macrophages (HLM), mononuclear cell infiltration (MCI) and fibrosis were found to be statistically significant (P < 0.01, P < 0.05, P < 0.005, respectively). When group 3 was compared with control group, the differences in HLM, MCI and fibrosis were also found to be statistically significant (P < 0.05, P < 0.05, P < 0.005, respectively). In the comparison of group 2 with group 3, no statistically significant differences were found in terms of the these parameters. CONCLUSIONS: Although MMC is toxic at high doses, the antifibrotic effect of the intraurethral low dose MMC may be useful in combination therapy for internal urethrotomy. 相似文献

Summary. This report analyses 1234 patients with CIN and noncondylomatous wart virus infection (NCWVI) managed by CO2 laser ablation in the Regional Department of Gynaecological Oncology, Queen Elizabeth Hospital, Gateshead from 1979 to 1983. Thirty-five patients (3%) were lost to follow-up. Of the 1157 patients currently under review and with at least 1 year of follow-up, 44 (3·8%) were laser treatment failures. This group is analysed and the results compared with other series. 相似文献

The clinical and bacteriologic efficacy of topically applied ciprofloxacin was studied in 60 patients with chronic suppurative otitis media. Two hundred fifty and 125 μg/ml concentrations of ciprofloxacin solutions were given to two groups of patients. The duration of therapy was determined according to the clinical cure at follow-up. More than 21 days of therapy was not needed in any patient. The clinical cure rate with 250 μg/ml ciprofloxacin was 78.1% at 14 days and with 125 μg/ml it was 83.3%. However, a 100% clinical cure rate and complete bacteriologic eradication was obtained in 21 days in both groups. In each group only one patient had otomycosis by the fourteenth day of therapy, although ear discharge had ceased. It was concluded that 125 μg/ml ciprofloxacin could be applied as successfully as 250 μg/ml, and the duration of therapy had to be at least 14 days. This new dosage regimen can be adopted as an optimal dosage for ototopical application of ciprofloxacin in chronic suppurative otitis media. It will also obviously decrease the expense of therapy.
