본 연구는 생쥐의 중추신경계통에서 고장액에 반응하여 c-Fos에 대한 면역양성을 나타내는 지역을 규명하고자 수행하였다. c-Fos의 발현은 면역조직화적으로 검출하고 신경세포의 활성화에 대한 표식자로 이용하였다. 고장액은 생쥐 뇌의 supraoptic nuclus, median preoptic nucleus organum vasculosum lamina terminalis, sufornical organ, locus coeluleus, nucleus of solitary tract, ventrolateral medulla, parabrachial nucleus 등에서 발현되었다. 특히 retrochiasmatic area의 배쪽 부분에서 많은 c-Fos면역양성의 세포가 관철되었으며, 시상하부의 paraventricular nucleus나 두뇌의 area postrema에서는 c-Fos면역양성세포가 거의 관철되지 않았는데 이들 지역들은 흰쥐에서는 다수의 c-Fos면역양성 세포가 나타나는 지역이다. 이상의 결과들은 생쥐에서 고장액이에 의해 c-Fos면역양성 세포가 나타나는 지역은 흰쥐에서와는 일부 상이한 결과를 보여주는 것으로 나타났다. Experiments were carried out on adult mouse to investigate the regional localization of the cells inducing c-Fos immunoreactivity in central nervous system in response to hypertonic saline(HS). c-Fos induction, detected immunohistochemically, was regarded as a marker for neuronal activation. Intraperitoneal injection of HS resulted in dense c-Fos-like immunoreactivity (FLI) in several forebrain and brainstem area. These areas include the supraoptic nucleus(SON), median preoptic nucleus (MnPO), organum vasculosum lamina terminalis(OVLT), subfornical organ(SFO), locus coeruleus(LC), nucleus of solitary tract(NTS), ventrolateral medulla(VLM), and parabrachial nucleus(PBN). In particular, the ventral region of retrochiasmatic area showed numerous and very intensely labeled FLI cells. No FLI or few FLI cells were, however, detected in the hypothalamic paraventricular nucleus (PVN) and the area postrema(AP) respectively, the regions which revealed very intensive FLI in rat after HS treatment. These data suggest that FLI induced in response to osmotic stimuli in the mouse brawn has a different regional distribution from that of rat brain.

Recent efforts on unique and flexible battery designs are working towards advanced batteries that can be applied to devices and applications without limiting their form factors. Recently, several groups have demonstrated promising results in the area of flexible lithium rechargeable batteries using various types of materials and processes. Importantly, liquid electrolytes limit choices in cell design of flexile lithium rechargeable batteries due to their fluidic characteristics and the need of separators in cell assembly even though their excellent electrochemical performance and good physical contact with electrode. This situation motivates us to develop self-supporting electrolytes paste that can be prepared on the electrode surface directly via roll-to-roll screen-printing process. In this work, we have newly designed novel polymer electrolytes with unique rheological propertie.
