©2004 Society for Neuroscience ; Both brain-derived neurotrophic factor (BDNF) and adenosine influence neuronal plasticity. We now investigated how adenosine influences the action of BDNF on synaptic transmission in the CA1 area of the rat hippocampal slices. Alone, BDNF (20 –100 ng/ml) did not significantly affect field EPSPs (fEPSPs). However, a 2 min pulse of high-K+ (10 mM) 46 min before the application of...
As dermatofitoses são os distúrbios infecciosos de pele mais comuns do mundo. Na presente pesquisa foram avaliados 2.297 pacientes com lesões clínicas sugestivas de dermatofitoses das quais, 534 (23,2%) mostraram-se positivas para dermatófitos. Destes, o T. rubrum foi a espécie mais prevalente (49,6%; p <= 0,05), seguido por T. tonsurans (34,4%; p <= 0,05), M. canis (7%) e T. mentagrophytes (6,2%). Ao correlaci...
Nowadays 70% of the world's rubber supply is synthesized artificially. The process involved in its manufacture is vulcanization which requires many chemical substances for speeding the process, as antioxidants to prevent deterioration of rubber, or others. These substances may constitute important sensitizers and thus be responsible for dermatological diseases like contact dermatitis. The objective of this stud...
This work consists in an evaluation of the occurrence of nickel contact dermatitis, its distribution between sexes and in which parts of the body the dermatitis usually occurs. It was accomplished a two year (1994-1995) retrospective study of 404 patch-tested patients which had previous clinical diagnosis of contact dermatitis. The occurrence of nickel sensitisation was 19,8%. 88,8% of these 19,8% were women an...
São estudados aspectos clínicos e epidemiológicos da dermatite de contato pela pederina, zoodermatose observada em vários municípios do Estado do Ceará, durante o período de chuvas, principalmente nos meses de abril e maio. O agente etiológico desta enfermidade é um coleóptero do gênero Paederus, tendo sido identificadas duas espécies em nosso meio: Paederus brasiliensis e Paederus Columbians.
