Amined the effect on the chronic therapy with lithium on the survival of BrdU(+) cells in ?the dentate gyrus of naive and impaired animals. The cell survivability was assessed by counting the BrdU(+) cells remaining inside the dentate gyrus on day 30 post-treatment with PBS or TMT (Figure four). At this time window, the number of surviving BrdU(+)Advantageous Impact of Lithium on Neuronal RepairFigure two. Effect of lithium (Li) on BrdU incorporation following neuronal loss. Animals had been offered either lithium carbonate (one hundred mg/kg, i.p.) or PBS alone with BrdU on day two post-treatment with TMT, then decapitated on day three (Schedule 1). For Schedule two, animals were provided when each day either lithium carbonate (100 mg/kg, i.p.) or PBS on days 3 and four, after which decapitated on day 5 post-TMT therapy. The sagittal hippocampal sections had been then stained with anti-BrdU antibody.

Comparing cells positive for each NeuN and BrdU in between the ?naive and impaired animals, no substantial adjust within the numbers of these cells was observed inside the GCL+SGZ. The chronic therapy with lithium enhanced the amount of NeuN(+)-BrdU(+) cells in this region from the impaired animals. Nevertheless, lithium was ineffective in altering the number of these cells in the GCL+SGZ ?on the naive animals. There was also a lithium-induced boost inside the quantity of DCX(+)-BrdU(+) cells observed in the GCL+SGZ from the impaired animals. To detect newly-generated astrocytes and microglial cells ?following neuronal loss inside the dentate gyrus from the naive and impaired animals, we determined the numbers of GFAP(+)BrdU(+) and Iba1(+)-BrdU(+) cells (Figure six). GFAP(+)-BrdU(+) cells were not considerably changed in quantity in the GCL+SGZ ?in between the lithium and PBS groups in either naive or impaired animals. Similarly, the amount of Iba1(+)-BrdU(+) cells in the dentate gyrus was not changed by the lithium remedy.Figure three.
