چکیده
RESUMEN. Doce ratas Sprague-Dawley fueron sujetas a la lesión de la fimbria fornix (transección de la vía septohipocampal). Seis de estos animales recibieron inyecciones intraventriculares de 3 pg de factor de crecimiento nervioso (FCN) en días alternos y durante dos semanas, mientras que los otros seis recibieron citocromo c en igual esquema y dosis (controles). La actividad específica de la glutatión S-transferasa (GST) se midió en el septum, el hipocampo, el estriado y la corteza frontal. Los animales tratados con FCN mostraron un incremento significativo (p < 0,002) de la actividad de la GST en el septum. No hubo diferencias entre los grupos en las otras estructuras estudiadas. Este incremento en la actividad de la GST puede estar vinculado con el efecto protector del FCN sobre la población colinérgica septal . ABSTRACT. Bilateral fimbria fornix lesion (septohippocampal pathway transection) was performed on 12 male Sprague -Dawley rats. Six animals received intraventricular injections of 3 Fgo f nerve growth factor (NGF) on alternate days for two weeks. Six animals received the same amount of cytochrome c (controls). The glutathione S-transferase (GST) specifíc activity was measured in septum, hippocampus, striatum and frontal cortex. A significant increase of GST activity (p < 0.002) was found in the septum of the NGF-treated animals. No differences were found between groups in the other areas. This increase in GST activity might be related to the protecting effect of NGF on the cholinergic septal population.

Glutathione S Transferase Activity in the Basal Forebrain Cholinergic Population
The role of glutathione S transferase (GST) in the detoxification mechanisms in different organs is discussed in recent papers. In rat brain, where GST is located in the astrocytes/1-3/, the information concerning this topic is scarce. We present information about the levels of GST specific activity (GST-SA) in different rat brain areas and the effect of placental tissue homogenate (PTH), which...
متن کاملCholecystokinin-8 protects central cholinergic neurons against fimbria-fornix lesion through the up-regulation of nerve growth factor synthesis.
In this study, we demonstrate that cholecystokinin-8 (CCK-8) induces an increase in both nerve growth factor (NGF) protein and NGF mRNA in mouse cortex and hippocampus when i.p. injected at physiological doses. By using fimbria-fornix-lesioned mice, we have also demonstrated that repeated CCK-8 i.p. injections result in recovery of lesion-induced NGF deficit in septum and restore the baseline N...

Basic fibroblast growth factor (bFGF) and nerve growth factor (NGF) were administered into the rat brain following unilateral fimbria-fornix transection. Both bFGF and NGF stimulated the sprouting of acetylcholinesterase (AChE) positive fibers in the hippocampus on the lesioned side. Furthermore, a small number of AChE-positive fibers were regenerated even when only the vehicle was administered...

Two groups of Sprague-Dawley male rats received bilateral aspirative lesions of the fimbria fornix under chloral hydrate anesthesia. One group (n = 9) received no further treatment (lesioned). In the second group (n = 8), a piece of septal fetal tissue, obtained at day E15-16, was implanted into each lesion cavity (transplanted). A third group consisted of shamlesioned rats (controls, n = 14). ...
