THIS study intended to characterize pharmacologically the mediator(s) released in the inflammation induced by Soluble Egg Antigen (SEA), the main antigen released from eggs of Schistosoma mansoni, in rat hindpaws. A single intraplantar injection of 0.1-100 microg SEA at day zero induced a dose-dependent increase in the volume of rat hindpaws characterizing an oedema of quick onset (within 15 min) and 4h-duration, which was confirmed by histopathological analysis of the paws. A second injection of SEA in the same paw (1-10 microg) 28 days later induced an increased dose-dependent oedematogenic response. The early oedematogenic response following SEA sensitization was derived from serotonin release and interleukin-1 (IL-1), since treatment with either pizotifen or an antibody against IL-1, reduced the response by 60% and 48%, respectively. The increased oedematogenic response derived from SEA-challenge (10 microg) of rat paws derived from a local rather than systemic reaction, since it was not observed if the sensitization was in the contralateral paw or the peritoneal cavity of the animals. Chronic treatment with inhibitors of IL-2 synthesis/release such as cyclosporin or dexamethasone during the sensitization phase reduced the oedematogenic response due to SEA challenge by 51% and 55%, respectively. These data suggested that SEA-challenge was immune-derived and dependent of IL-2 release. It is discussed the association between cytokine release and the resistance of rats to S. mansoni infection. 相似文献

Summary The aim of this study was to obtain an estimate of the frequency of the ΔF508 mutation in the Portuguese population, and of
the tightness of its association with specific haplotypes. Furthermore, the genotype/clinical phenotype relationship and the
feasibility of prenatal diagnosis were also investigated. The analysis of 42 cystic fibrosis (CF) families revealed that (1)
52% of CF chromosomes carry the deletion of codon 508; (2) there seems to be a positive correlation between the occurrence
of the ΔF508 mutation and the severity of the disease; and (3) fully informative prenatal diagnosis can be offered in 76%
of at-risk pregnancies by using both genomic and allele specific oligonucleotide probes. 相似文献

A biofilm of Arthrobacter viscosus, supported on granular activated carbon, removed between 100% and 50% of Cr(VI) and between 100% and 20% of Cd(II) from solutions with initial concentrations between 4–11 mgmetal l–1 and a flow residence time of 1.2 min. For experiments of lower initial concentrations, a steady-state removal of 50% was reached after 71 bed volumes of Cr solution passed through the biosorbent bed and a steady-state removal of 30% was reached after 47 bed volumes of Cd solution passed through a similar bed. Final uptakes of 8.5 mgCr gcarbon
–1 and 4.2 mgcd gcarbon
–1 were determined for initial concentrations of 10 mgCr l–1 and 11 mgCd l–1, respectively. The influence on the overall process of two different surface treatments of the support was evaluated and compared with the behavior of a support not treated. 相似文献

Genome size estimates and their evolution can be useful for studying the phylogenetic relationships and taxonomy of a particular group. In the present study, the genome sizes of the three species that comprise the Mycetophylax genus were estimated by flow cytometry (FCM). There was little variation in genome size among them. The mean haploid genome size value of male and female individuals of Mycetophylax morschi was 312.96 Mbp (0.32 pg) and that of Mycetophylax conformis and Mycetophylax simplex females were 312.96 Mbp (0.32 pg) and 381.42 Mbp (0.39 pg), respectively. At first glance, this variation could be related with the heterochromatin content. Our results, together with other previous reports, have contributed to our knowledge about Attini genome size and will be useful to improve the understanding of the evolution of this tribe. It will help select potential model species in Attini for future genomic and sequencing projects. 相似文献

The performance of a biofilm of Arthrobacter viscosus supported on granular activated carbon on the retention of organic compounds was evaluated. The presence of functional groups
on the cell wall surface of the biomass that may interact with the organic compounds was confirmed by Fourier transform infrared
spectroscopy, to assess the applicability of this system to the removal of those compounds. The batch assays showed that the
removal percentage decreases with the increasing initial concentration. The removal of phenol ranged from 99.5 to 93.4%, the
chlorophenol removal ranged from 99.3 to 61.6% and the o-cresol removal ranged from 98.7 to 73.5%, for initial concentrations between 100 and 1,700 mg/L. The batch data were described
by Freundlich, Langmuir, Redlich–Peterson, Dubinin-Radushkevich, Sips and Toth model isotherms and the best fit for the retention
of phenol and for the retention of o-cresol was obtained with the Sips model, while for chlorophenol, the best fit was obtained with the Freundlich model. The
column tests showed that the retention performance followed the order: phenol > chlorophenol > o-cresol, and increased with the increasing initial organic compound concentration. Data from column runs were described by
Adams–Bohart, Wolborska and Yoon and Nelson models with good fitting for all the models. 相似文献
