Title in Portuguese
"Modulação térmica da lesão isquêmica: estudo in vitro"
Keywords in Portuguese
Apoptose
Hipotermia
Isquemia cerebral
Neuroblastoma
Abstract in Portuguese
A isquemia cerebral causada pela parada cardíaca leva ao desapareciemnto neuronal. studamos os mecanismos de morte celular envolvidos na isquemia in vitro em linhagem de neuroblastoma.O insulto isquêmicao foi reproduzido cultivando as células sem fatores de crescimento, sem glicose e em embiente hipóxico produzido por um sistema de anaerobiose. Os resultados sugerem que a privação de oxigênio, glicose e fatores de cresciemtno do meio de cultura reproduzem o fenômeno semelhante a isquemia. INvestigamos ainda a participação de processo apoptótico e sua modulação térmica. Observams que a hipotermia produz neuroproteção, enquanto a hipertermia agrava o processo de morte celular por apoptose.
Title in English
Temperature modulation of the ischemic neuronal loss in vitro
Keywords in English
Apoptose
Cerebral ischemia
Hypothermia
Neuroblastoma
Abstract in English
Cardiac arrest causes cerebral ischemia and neuronal disappearance. We investigate celular death mechanisms elucidated by a model of ischemia in neuroblastoma cell line. The ischemic insult was reproduced by deprivation of growth factors and glucose in a hypoxic environment produced by an anaerobiosis system. Our results validate the experimental model and revel the participation of an apoptotic process in the celular loss induced by ischemia. We also demonstrated that hypothermia can be used as a neuroprotector agent whereas hyperthermia aggavates celular damage.
