Neuroprotective effects of mild hypoxia in organotypic hippocampal slice cultures
Seh Hyun Kim, Woo Soon Lee, Na Mi Lee, Soo Ahn Chae, Sin Weon Yun
Clin Exp Pediatr. 2015;58(4):142-147.   Published online April 22, 2015
Purpose

The aim of this study was to investigate the potential effects of mild hypoxia in the mature and immature brain.

Methods

We prepared organotypic slice cultures of the hippocampus and used hippocampal tissue cultures at 7 and 14 days in vitro (DIV) to represent the immature and mature brain, respectively. Tissue cultures were exposed to 10% oxygen for 60 minutes. Twenty-four hours...

Susceptibility of rat hippocampal neurons to hypothermia during development
Kyung Ah Seo, Sehhyun Kim, Na Mi Lee, Soo Ahn Chae
Clin Exp Pediatr. 2013;56(10):446-450.   Published online October 31, 2013
Purpose

This study evaluated the extent of damage due to hypothermia in the mature and immature brain.

Methods

Hippocampal tissue cultures at 7 and 14 days in vitro (DIV) were used to represent the immature and mature brain, respectively. The cultures were exposed at 25℃ for 0, 10, 30, and 60 minutes (n=30 in each subgroup). Propidium iodide fluorescent images were captured 24...

Case Report
Signal change in hippocampus and current source of spikes in Panayiotopoulos syndrome
Jung Sook Yeom, Youngsoo Kim, Ji Sook Park, Ji Hyun Seo, Eun Sil Park, Jae Young Lim, Chan-Hoo Park, Hyang Ok Woo, Hee-Shang Youn, Oh-Young Kwon
Clin Exp Pediatr. 2012;55(2):63-67.   Published online February 14, 2012

A 4-year-old girl with Panayiotopoulos syndrome presented with a history of 4 prolonged autonomic seizures. The clinical features of her seizures included, in order of occurrence, blank staring, pallor, vomiting, hemi-clonic movement on the right side, and unresponsiveness. A brain magnetic resonance imaging (MRI) showed a slightly high T2 signal in the left hippocampus. Interictal electoencephalogram revealed spikes in the...

A case of hippocampal sclerosis diagnosed as cortical dysplasia due to preoperative brain MRI finding
Jun Seok Lee, Kyo Ryung Kim, Jeong Tae Kim, Min Jung Choi, Young Mock Lee, Heung Dong Kim, Joon Soo Lee, Dong Seok Kim, Tae Seong Kim
Clin Exp Pediatr. 2010;53(1):106-110.   Published online January 15, 2010
Hippocampal sclerosis (HS) is one of the most common features of intractable temporal lobe epilepsy. Generally it can be identified through brain magnetic resonance imaging (MRI) with high degree of sensitivity and specificity. Typical brain MRI findings of HS are hippocampal atrophy with hyperintense signal confined to the lesion. On the other hand cortical dysplasia exhibits blurring of the gray-white...

Injury of neurons by oxygen-glucose deprivation in organotypic hippocampal slice culture
David Chanwook Chung, Kyung Sik Hong, Jihui Kang, Young Pyo Chang
Clin Exp Pediatr. 2008;51(10):1112-1117.   Published online October 15, 2008
Purpose : We intended to observe cell death and apoptotic changes in neurons in organotypic hippocampal slice cultures following oxygen-glucose deprivation (OGD), using propidium iodide (PI) uptake, Fluoro-Jade (FJ) staining, TUNEL staining and immunofluorescent staining for caspase-3. Methods : The hippocampus of 7-day-old rats was cut into 350 µm slices. The slices were cultured for 10 d (date in vitro, DIV...

Recurrent Early-Life Seizures and Changes in GABAA Receptors Expression in Hippocampus
Doo Kwun Kim
Clin Exp Pediatr. 2004;47(6):596-603.   Published online June 15, 2004
The immature brain differs from the adult brain in its susceptibility to seizures, seizure characteristics, and responses to antiepileptic drugs. Gamma(γ)-aminobutyric acid(GABA) is the predominant inhibitory neurotransmitter in the adult brain. GABA exerts its main action through GABAA receptors, which are coupled to a ligand-gated chloride channel. The receptor protein is a pentameric structure composed of multiple subunits of different...

Apoptosis, P53, bax and Bcl-2 Protein Expressions in Neonatal rat Hippocampus by Kainic Acid-induced Seizure
Shin Weon Yun, Soo Ahn Chae, Eung sang Choi, Byoung Hoon Yoo
Clin Exp Pediatr. 2000;43(1):85-96.   Published online January 15, 2000
Purpose : Apoptosis is a process of active cell death which has been suggested to be part of hippocampal cell loss caused by kainic acid(KA). Immature rats showed higher susceptibility and mortality to KA but did not develop recurrent seizure, long term behavioral or neuropathologic changes. We investigated whether this was due to age-dependent resistance, and elucidated the molecular mechanics which mediate P53-induced apoptosis,...
