笔者分别对125例Aids与正常人、SLE与正常人进行比较基础上。对125例Aids和SLE配对,用ICP法测35种元素,在本文报告31种元素检验结果,经t一检验:平均值的成对二样分析发现:Aids与SLE发检结果比较:Bi、Li、Mn、Ti、A1等5种元素含量为正相关;而Cu、Co、Ge、Mo、Sb、Ce、La、Ga、Th等9种元素含量呈负相关。从而揭示了免疫缺陷病毒感染者与系统性红斑狼疮患者体内元素代谢的差异,为当今世界攻克免疫性疾病指出方向,证明元素平衡医学食疗是解决Aids、SLE、癌症等免疫性疾病必由之路。 相似文献

Objectives
The aims of this study were to find and compare the effect of directional (DIR) processing of two different hearing aids via both subjective and objective methods, to determine the association between the results of the subjective and objective evaluations, and to find out individual predictive factors influencing the DIR benefit.Methods
Twenty-six hearing aid users fitted unilaterally with each two different experimental hearing aid performed modified Korean Hearing in Noise Test (K-HINT) in three DIR conditions; omnidirectional (OMNI) mode, OMNI plus noise reduction feature, fixed DIR mode. In order to determine benefits from DIR benefit within a hearing aid and compare performance of the DIR processing between hearing aids, a subjective questionnaire was administrated on speech quality (SQ) and discomfort in noise (DN) domain. Correlation analysis of factors influencing DIR benefit was accomplished.Results
Benefits from switching OMNI mode to DIR mode within both hearing aids in K-HINT were about 2.8 (standard deviation, 3.5) and 2.1 dB SNR (signal to ratio; SD, 2.5), but significant difference in K-HINT results between OMNI and OMNI plus noise reduction algorithm was not shown. The subjective evaluation resulted in the better SQ and DN scores in DIR mode than those in OMNI mode. However, the difference of scores on both SQ and DN between the two hearing aids with DIR mode was not statistically significant. Any individual factors did not significantly affect subjective and objective DIR benefits.Conclusion
DIR benefit was found not only in the objective measurement performed in the laboratory but also in the subjective questionnaires, but the subjective results was failed to have significant correlation with the DIR benefit obtained in the K-HINT. Factors influencing individual variation in perceptual DIR benefit were still hard to explain. 相似文献5.

Zum Thema
Seit Einführung der antiretroviralen Medikamente, insbesondere der Proteaseinhibitoren, hat die Mortalit?t und Morbidit?t
der HIV-Infektion signifikant abgenommen. Eine h?ufige Nebenwirkung dieser Therapie ist das Lipodystrophiesyndrom, ein vielf?ltiger,
aber charakteristischer Symptomenkomplex, der durch k?rperliche und metabolische Ver?nderungen gekennzeichnet ist. Dieses
Syndrom besteht aus einer charakteristischen Fettverteilungsst?rung mit einer Zunahme des intraabdominalen Fetts, der Bildung
eines “Stiernackens” und zugleich einem Schwund des subkutanen Fetts an den Extremit?ten und im Gesicht. Dazu k?nnen eine
Hyperlipid?mie und eine Insulinresistenz kommen. Die Pathogenese des Lipodystrophiesyndroms ist nicht gekl?rt. 相似文献

对一名女性重度耳聋患者,她仅在500Hz以下有一定残余听力,对其使用赛佛助听器时的听力改善,进行了实验研究。采用的方法是进行言语可懂度测试和辅音知觉混淆矩阵分析。在三种不同的条件下进行可懂度测试:(1)不带助听器;(2)只带助听器不加唇读;(3)既带助听器又加唇读。结果表明:(1)赛佛助听器有利于提高声调识别率;(2)使用赛佛助听器,多音节词可懂度提高得比单音节词要多;(3)赛佛助听器可使单词可懂度提高40%,音节清晰度提高25%;(4)赛佛助听器对改善辅音发音方法的感知帮助较大,而对发音部位的感知帮助不大。 相似文献

Rational Decision-Making (RDM) models, which focus on individuals' cognitions and attitudes. have been applied to the explanation of HIV/AIDS risk behaviour. The concept of rational choice which underpins RDM models has, however, been found to be inadequate to explain young people's sexual risk-taking behaviour. The current paper uses primarily qualitative data from a study of HIV/AIDS risk behaviour among young drug injectors to explore whether or not needle sharing behaviour could be explained by RDM models. In general, we found it could not: some young injectors, despite knowing that HIV can be transmitted through needle sharing and thai AIDS is fatal, continued to share needles. It was clear, however, that behaviour that appeared irrational from the perspective of RDM models, was not irrational from the perspective of the actors. The paper concludes with a plea for health promotion and education to be based on understandings of injecting risk behaviour which address all the individual, cultural and societal constraints that operate to prevent young injectors from acting safely. 相似文献

Tuberculosis has now been well documented as a complication of infection with human immunodeficiency virus (HIV), but no studies concern patients requiring admission to the ICU. We report 12 cases of severe disseminated tuberculosis in patients who were seropositive for HIV. Eight patients had diffuse pulmonary involvement responsible for acute respiratory failure, 7 of whom required mechanical ventilation. Four developed septic shock, and in 3 blood cultures were positive forM. tuberculosis. Four patients had central nervous system involvement, with coma requiring mechanical ventilation 3 times. Rapid diagnosis was permitted in 10 patients by acid-fast smears of pulmonary specimens (8 patients) and/or tissue biopsies (4 patients). Seven patients died despite intensive therapy; autopsy was performed in 4 patients, showing disseminated tuberculosis. On the basis of this report, tuberculosis in HIV infection may present as an overwhelming systemic disease and thus requires an aggressive diagnostic and therapeutic approach. 相似文献
