PURPOSE: It was reported that gene locus for generalized epilepsy with febrile seizures plus(GEFS+) exist in chromosome 19q13.1, and has relationship with a 387 C G mutation in the SCN1B gene. This study is to determine whether there is the 387 C G mutation in the children with GEFS+ and simple febrile seizures(FS). METHODS: The sample group consisted of 16 patients with GEFS+ and 10 patients with FS who were diagnosed by our department of pediatrics from Jan. 1998 to Dec. 1999. The control group consisted of 15 children who do not have seizure disorders. Genomic DNA was extracted from peripheral blood and a segment of the SCN1B exon 3 was amplified by PCR technique. Purified PCR products were treated with restriction enzyme, Hin P1. The restriction pattern was analyzed by sequencing analysis. RESULTS: Sixty nine%(11 of 16) patients with GEFS+ had family history for epilepsy, and epilepsy phonotypes were generalized tonic-clonic seizures in 82%(13 of 16), on the other hand 12%(2 of 16) and 6%(1 of 16) had absences and atonic seizures respectively. EEG findings showed generalized spike and wave in the all patients with GEFS+. in this study, however we could not observe a 387 C-->G mitation of the SCN1B in the children with GEFS+ and febrile seizures. CONCLUSION: The gene for GEFS+ may have a heterogenetic characteristics, and there may be racial differences in mutation frequency. Expanded studies involving large number of different families are required.

PURPOSE: To investigate the neuroprotective effect of growth hormone(GH) on neuronal cell necrosis and apoptosis at 1 week and 3 weeks after hypoxic ischemic brain injury. METHODS: Sprague-Dawley rats, seven-day-old, were used. Rats were anesthetized with ether less than 5 minutes. The right carotid artery was cut between double ligation. And then, rats were allowed to recover for 30 minutes followed by exposure to 8% oxygen at 37 degrees C for 2 hours for hypoxic ischemic insult. The study group was divided into 2 groups, control group(N=3) and GH treated group(N=3). GH treated group received intraperitoneal injection of GH 1 IU 2 hours after hypoxic ischemic insult following daily adminstration as same dose for 5 days. Rats were decapitated at 1 week and 3 weeks after hypoxic ischemic brain injury. After then, right hippocampal CA1 and CA3 neurons of rat brains were examined. RESULTS: Necrosis was significantly less in GH treated group than control group, and was more prominent at 3 weeks in both groups. The apoptosis was not found in GH treated and control group. CONCLUSION: GH has a neuroprotective effect on neuronal cell deaths(especially necrosis) from 1 week to 3 week after hypoxic ischemic insult in neonatal rat.

PURPOSE: The growth hormone receptor(GHR) is essential for the actions of growth hormone on postnatal growth and metabolism. GHR transcripts are characterized by the presence of disparate 5'untranslated exons. In contrast to L1 transcript, factors regulating the expression of the GC rich L2 transcript have remained unidentified. The purpose of this study is in order to characterize the mechanisms regulating expression of the L2 transcript in the murine GHR gene METHODS: Transient transfection experiments including deletional analysis and co-transfection assay were performed to find a region containing promoter activity in the L2 5'flanking sequence using BNCL2(mouse liver) cells, CV-1(African green monkey kidney) cells, HRP.1 trophoblasts and Drosophila Schneider(SL2) cells. Sequencing analysis was performed to find the region contained consensus binding sites for transcription factors. Standard gel shift(Electrophoretic mobility shift assay, EMSA) and supershift analysis using liver nuclear extracts was performed to establish proteins(transcription factors) bound this regulatory element. RESULTS: The 5'flanking region of the L2 untranslated region(UTR) exhibited promoter activity in BNCL2(mouse liver), CV-1(monkey kidney) cells and HRP.1 trophoblasts. Deletional analyses indicated the presence of a Sp binding site important for transcription of the L2 UTR and localized the major regulatory region within 75 bp of the 5'transcription start site. Sequencing analyses revealed the region contained consensus binding sites for the Sp family of transcription factors. EMSA and supershift EMSA revealed that in mouse liver nuclear extracts that Spl and Sp3 bound to this cis-element. Functional studies in Drosophila SL2 cells and BNCL2(mouse liver) cells established the ability of Sp3 and Sp1 to stimulate transcriptional activity via this cis-element. Functional studies in Drosophila SL2 cells demonstrated a functional interaction between Sp3 and Sp1 at this DNA-binding site. CONCLUSION: Sp family transcription factors play a role in regulation of L2 transcript gene expression in the 5'flanking region of the murine GHR gene.
