Glial activation in a pilocarpine rat model for epileptogenesis: a morphometric and quantitative analysis.

In this work we examined the correlation between long-term glial resilience and slow epileptogenesis using the pilocarpine-insult rat model. We assessed, quantitatively and morphometrically, glial fibrillary acidic protein (GFAP) expression and cell densities in hippocampus in a dose-response manner 2, 4 and 8 weeks after the pilocarpine insult. GFAP changes were correlated with observations on microglial activation.

[Physiopathologic changes in brain death. Their importance for management and organ donation decisions].

Technological advances in the medical area have allowed for development of useful techniques to treat patients with diverse diseases. For example, at intensive care units this technology allows maintenance blood flow and tissue oxygenation even when brain death (BD) is already established and the individual cannot function. The function of heart, lungs, and other organs can be maintained with different devices, but maintenance of cerebral functions is not not yet possible.
