Said B Iskandar Mathew G Mathai Ryland P Byrd Thomas M Roy 《The Journal of asthma》2004,41(3):337-342
Asthma affects 5%-10% of adults in the United States. Older adults (> 65 years) with asthma have higher rates of fatal asthma than younger adults. The occurrence of a respiratory emergency, such as status asthmaticus, would seem likely to create a situation of cardiopulmonary dysfunction conducive to myocardial ischemia. However, multiple studies of fatal or near-fatal asthma have failed to incriminate myocardial infarction as a contributing factor. We report a patient without underlying coronary artery disease who sustained myocardial injury consistent with myocardial ischemia and infarction during status asthmaticus while receiving recommended treatment without intravenous sympathomimetics or theophylline. 相似文献

The specificity and sensitivity of an indirect and two (an ‘ordinary’ and a ‘rapid’) double sandwich enzyme-linked immunosorbent assay (ELISA) procedures for the quantitation of Calloselasma rhodostoma (Malayan pit viper) venom were examined. The three assays were equally sensitive and the accuracy of the assays was not substantially affected by individual variation in the venom composition. The specificity of the assays was examined against 26 venoms from snakes of the families Viperidae and Elapidae. While the double sandwich ELISA procedures were sufficiently specific to be used in the clinical immunodiagnosis of C. rhodostoma bite in Malaysia, the indirect ELISA procedure exhibited extensive cross-reactivity with other Malaysian pit viper venoms. Attempts were made to improve the specificity of the indirect ELISA procedure for the quantitation of C. rhodostoma venom. A ‘low ELISA cross-reactivity’ venom fraction (termed VF52) was isolated from C. rhodostoma venom by repeated Sephadex G-100 gel filtration chromatography. The indirect ELISA procedure using antibodies to VF52 as immunoreagent showed an improvement in specificity. The use of the indirect ELISA procedure for the detection of C. rhodostoma antibodies was also examined and the results show that the assay was sufficiently specific to be used for retrospective diagnosis of C. rhodostoma bite in Malaysia, in particular when VF52 was used as the coating antigen. 相似文献

We report a case of primary cerebral lymphoma metastasizing to the kidney with exclusive involvement of the glomeruli. We discuss the possible explanations of this unusual phenomenon, and present some of the unusual clinical features of the case. Nephropathologists interpreting glomerular hypercellularity should always consider metastatic neoplasms as a possible, though rare, cause. 相似文献

Interaction of antigen load and antibody response in determining heterologous protein nephritogenicity in inbred mice 总被引:2,自引:0,他引:2
S S Iskandar J C Jennette 《Laboratory investigation; a journal of technical methods and pathology》1983,48(6):726-734
Genetically disparate inbred mouse strains mounting quantitatively different immune responses to a potentially nephritogenic heterologous protein had varied development of glomerulonephritis (GN) dependent upon the interaction between level of antibody response and antigen dose. High responder BALB/c mice given high doses of horse apoferritin developed a severe necrotizing GN. BALB/c mice given low dose horse apoferritin developed less severe GN, or when antibodies were in extreme excess, no GN. Low responder C3H mice given high dose horse apoferritin were in extreme antigen excess and developed no GN. C3H mice given low dose horse apoferritin developed a glomerulopathy characterized by capillary loop immune deposits. Interstrain differences in immune clearance and avidity did not account for this varied nephritogenicity, although avidity did relate to glomerular site of immune deposits in the BALB/c model. In the models under consideration susceptibility to heterologous antigen-induced glomerular injury was a function of the magnitudes of both the antibody response and the antigenic challenge. 相似文献
