N-methyl-D-aspartate (NMDA) receptors contribute to many brain functions. We studied the effect of forebrain-targeted overexpression of the NMDA receptor subunit NR2B on the response of mice to tissue injury and inflammation. Transgenic mice exhibited prominent NR2B expression and enhanced NMDA receptor-mediated synaptic responses in two pain-related(More)
Experiments were performed in male Sprague-Dawley rats (150-200 g). A silver clip (0.2 mm internal diameter) was placed on the left renal artery of rats. After operation the rats were divided into 4 groups sham group, 2K1C (two-kidney one clip) group, 2K1C+Arg (2K1C and L-Arg 150 mg/kg x d(-1) by drinking) group, and 2K1C+NAME (2K1C and L-NAME 10 mg/kg x(More)
In the studies of neural transplantation, Chen and his colleagues observed that the grafted central neurons could migrate from the subarachnoid space into the spinal cord and cerebral cortex. This finding promises an attractive possibility that a lot of neurons might be introduced into a long distance of the spinal cord and the extensive superficial layer(More)
The localization of the 35S-labelled AVP4-8 binding sites in the rat hippocampus was studied by using autoradiographic approach via observing the selective damages of hippocampal neurons by neurotoxins, and the developmental regulation of the hippocampal AVP4-8 receptor by pretreatment with exogenous AVP4-8 was observed. In adult rat hippocampus, the(More)
Transpial migration of implanted 5-HT neurons from the subarachnoid space into the spinal cord was studied in adult Wistar rats. Embryonic raphe tissue or cell suspension containing 5-HT cells was used as grafts. The implanted 5-HT cells were monitored by 5-HT immunohistochemical method. The results are as follows: (1) 10 d after cutting the spinal cord at(More)
In view of the fact that in embryonic and neonatal central nervous system (CNS), the pathway of developing fiber tracts is capable of guiding the axonal growth, it would be interesting to know whether a similar effect exists on the axonal growth in adult CNS. Embryonic fimbria was grafted into the hippocampus of the adult rat. Two weeks later, the grafts(More)
Groups of newborn Wistar rats received daily 1-desamino-8-D-arginine-vasopressin (DDAVP), oxytocin (OXT), hypertonic saline or normal saline for 14 days from day 1 to day 14 of life. One or three months later they were trained in a maze for brightness discrimination (BD). A group of untreated adult male rats received posttrial DDAVP or normal saline for(More)
