To clarify the question whether the duration of hypoxia exposure has an influence on the point in time or the strength of hypoxic preconditioning, hypoxia exposure of rats lasting 1 and 8 h was tested regarding the modification of susceptibility to acute pentylenetetrazol-induced seizures. Following the short-lasting (1 h) hypoxia, the maximum level of preconditioning action was observed 7 days after...
Hypoxia preconditioning states that a sublethal hypoxia period will afford neuroprotection against a second harmful event. In our experiments, we carried out a procedure for the development of hypoxia preconditioning in adult male Wistar rats using hypoxic exposure (9% O 2 ; 91% N 2 ) for 1 h. The protection against pentylenetetrazol (PTZ)-induced seizures was studied. For this, rats...
