Objective To explore the antiepileptic effect and mechanism of glucocorticoid. Methods Animal behaviour observation and immunocytochemical staining. Results Major epilepsy was induced by pentylenetetrazole(PTZ).Dexamethasone or diphenylhydantoin(DPH) administered in rat 30?min before administration of PTZ could suppress or inhibit epileptiform.Immunocytochemistry demonstrated that there was a large number of hypertrophic astrocytes with GFAP immunoreaction in cerebral cortex,hippocampal gyrus and dentate gyrus of epileptic rats induced by PTZ.The immunoreaction of GFAP was obviously weakened,the number of positive cells was reduced,the processes were shorter and less in both groups of antiepilepsy by GC or DPH.The expression of Fos protein was in a great quantity in cerebral cortex 1 to 1\^5 hours after seizure induced by PTZ,whereas their expressions were remarkable suppressed in GC or DPH antiepileptic groups. Conclusion 1\^The antiepileptic effect of GC was further proved by comparing with the antiepileptic effects of DPH(a traditional antiepileptic drug). 2\^Inhibited activity of astrocytes might be involved in antiepileptic mechanism of GC. 3\^The change of expression of Fos protein might be closely related to epileptic actions.

Objective To investigate the distribution of interleukin\|2 receptor (IL\|2R) and glucocorticoid receptor(GR) and identify coexistence of IL\|2R and GR in the rat brain. Methods The double labeling immunocytochemical technique(PAP method combined with ABC method), DAB and BDHC were used in the double labeling immunocytochemical method as the chromogens respectively. The reactive products of former was brown or yellow and later was black blue. Results IL\|2R and GR positive neurons were widely distributed in the cerebral cortex, hippocampus, thalamus, many motor and sense nuclei in the brain stem. The immunoreactive products of IL\|2R were found to be located on cell membrane and GR in nucleus and cytoplasm. There were a lot of positive double labeling neurons in the rat brain. The rate of double labeled cells in the total number of positive cells varied in different regions of brain, such as, 50 percent in cerebral cortex and 30 percent in nucleus of abducent nerve. Conclusion Immunogical cytokines and hormone could regulate the neuronal function through their corresponding receptors which coexisted in the same brain neurons. The present study might provide morphological evidence in the level of receptor for the immuno\|neuro\|endocrine network.

Mitogen-activated protein kinases (MAPKs) are important kinases involved in the intracellular signaling transduction in mammalian. There are three major MAPK pathways: ERK/MAPK,JNK/SAPK and P38 MAPK. Current studies indicate that all of them play significant roles in the processing of pain especially in the development and maintenance of pathological pain. This review will focus on in the study of MAPK in pain modulation. The further insights into its mechanisms may highlight a nice prospect for the therapies of painful diseases.
