Beneficial in vivo effect of aripiprazole on neuronal regeneration following neuronal loss in the dentate gyrus: evaluation using a mouse model of trimethyltin-induced neuronal loss/self-repair in the dentate gyrus.

Aripiprazole is used clinically as an atypical antipsychotic. We evaluated the effect of in vivo treatment with aripiprazole on the proliferation and differentiation of neural stem/progenitor cells in a mouse model, trimethyltin-induced neuronal loss/self-repair in the hippocampal dentate gyrus (referred as "impaired animals") [Ogita et al., J Neurosci Res.

[HPLC-method for deliberation of drug mammary transfer-evaluation of over-the-counter drugs (Loxonin(®)-S, Bufferin(®) A) in mother mice].

Loxoprofen (Loxonin(®)), an antipyretic painkiller, was approved as an over-the-counter (OTC) drug (Loxonin(®)-S) in January 2011. With regard to self-medication using OTC drugs, the information that pharmacists provide to consumers is very important. Although loxoprofen is a very versatile drug and can be used during breastfeeding, information regarding its mammary gland transfer is inadequate.

In vivo and in vitro treatment with edaravone promotes proliferation of neural progenitor cells generated following neuronal loss in the mouse dentate gyrus.

Edaravone is clinically used in Japan for treatment of patients with acute cerebral infarction. To clarify the effect of edaravone on neurogenesis in the hippocampus following neuronal injury in the hippocampal dentate gyrus, we investigated the effect of in vitro and in vivo treatment with edaravone on the proliferation of neural stem/progenitor cells prepared from the mouse dentate gyrus damaged by trimethyltin (TMT). Histological assessment revealed the presence of large number of nestin(+) cells in the dentate gyrus on days 3 - 5 post-TMT treatment.
