  • Atypical teratoid rhabdoid tumours (ATRTs) are the most common malignant central nervous system tumours in children ${\leq}1year$ of age and represent approximately 1-2% of all pediatric brain tumours. ATRT is a primarily monogenic disease characterized by the bi-allelic loss of the SMARCB1 gene, which encodes the hSNF5 subunit of the SWI/SNF chromatin remodeling complex. Though conventional dose chemotherapy is not effective in most ATRT patients, high dose chemotherapy with autologous stem cell transplant, radiotherapy and/or intrathecal chemotherapy all show significant potential to improve patient survival. Recent epigenetic and transcriptional studies highlight three subgroups of ATRT, each with distinct clinical and molecular characteristics with corresponding therapeutic sensitivities, including epigenetic targeting, and inhibition of tyrosine kinases or growth/lineage specific pathways.

  • Background: Epilepsy is a disorder of the central nervous system characterized by loss of consciousness and convulsions. Epilepsy, a typical chronic disease, may cause high level of psychosocial difficulties for all family members, including stigmatization, stress, martial problems, poor self esteem and restriction of social activities. Objective & Method: To demonstrate the therapeutic effect of herbal medicine (Kamigoakhyangjeonggisan) on patients with epilepsy. We treated two cases of epileptic children, who had frequent seizures. Results: Two children improved in the frequency of the seizure, the combined disabilities. Conclusion: We report that we had good effects of herbal medicine treatment on two cases of epileptic children.

  • Rhinocerebral mucormycosis is a rare but acutely fatal disease caused by fungi belonging to the order Mucorales, and characterized by an aggressive necrotizing infection spreading from the nose to the paranasal sinuses, orbit, and then to the central nervous system. It most frequently develops in individuals with poorly controlled diabetes mellitus. The authors report a 65-year-old woman who developed intracerebral hemorrhage during treatment for rhinocerebral mucormycosis associated with diabetes mellitus. Despite the treatment, she became worse. The pertinent literatures were reviewed.

  • Methylmercury (MeHg; $CH_{3}HgCl$) is, second only to cadmium as being, the most toxic on the earth. Inorganic mercury from various waste sources can be easily methylated by bacteria in water and subsequently ingested by fishes and then highly accumulated in human. Although toxicity from mercury exposure occurs with both organic and inorganic forms, organic mercury is more potently toxic to central nervous system. Minamata disease is an example of organic mercury toxicity. (omitted)

  • Contemporary studies illustrate that peripheral injuries activate glial components of the peripheral and central cellular circuitry. The subsequent release of glial stressors or activating signals contributes to neuropathic pain and neuroinflammation. Recent studies document the importance of glia in the development and persistence of neuropathic pain and neuroinflammation as a connecting link, thereby focusing attention on the glial pathology as the general underlying factor in essentially all age-related neurodegenerative diseases. There is wide agreement that excessive glial activation is a key process in nervous system disorders involving the release of strong pro-inflammatory cytokines, which can trigger worsening of multiple disease states. This review will briefly discuss the recent findings that have shed light on the molecular and cellular mechanisms of glia as a connecting link between neuropathic pain and neuroinflammation.

  • In Korea, tuberculosis is still common disease. Central nervous system tuberculosis can manifest in a variety of forms, including tuberculous meningitis, tuberculous cerebritis, tuberculoma, tuberculous abscess, and miliary tuberculosis. Although intra-axial tuberculomas are the more common type of CNS tuberculosis, extra-axial lesions are rarely encountered. En plaque tuberculoma is an extremely rare presentation of intracranial tuberculosis with mimicking primary or secondary meningeal neoplasia. We describe a rare case of an en plaque tuberculoma accompanied by tuberculous meningitis and tuberculomas.

  • In order to investigate the efficacy of combined preparations of crude drug, first, 'Kamisamhwang-Tang' were examined for pharmacological effect. Crude drug preparations were extracted successively with $H_2O$ and MeOH, and the extracts were developed on silicagel G plate were examined using the Dual-Wavelength TLC Scanner CS-910(Schimadzu) in ultra violet region. To estimate the clinical usefulness of 'Kamisamhwang-Tang' in heart disease (Symbyung syndrome), the above extracts were made an experiment on effects of the anticonvulsion, antipyretic, analgesic and sedative in mice, rats, and rabbits.

  • As the most common nutrition deficiency, iron deficiency not only causes anemia but also influences the central nervous system development. Its pathogenesis is supposed to be the alteration of neurometabolism and neurotransmission in major brain structures, and the disruption of myelination. The first two years after birth is a crucial period for cognitive, behavior, and emotional development with fast brain growth. If iron deficiency occurs in this period, cognitive and psychomotor function cannot be restored in spite of adequate iron supplementation. Thus, iron deficiency in infancy should be considered as a serious disease.

  • Gliomas are the most frequently occurring primary malignancies in the central nervous system, and glioblastoma multiforme (GBM) is the most common and most aggressive of these tumors. Despite vigorous basic and clinical studies over past decades, the median survival of patients with this disease remains at about one year. Recent studies have suggested that GBMs contain a subpopulation of tumor cells that displays stem cell characteristics and could therefore be responsible for in vivo tumor growth. We will summarize the major oncogenic pathways abnormally regulated in gliomas, and review the recent findings from mouse models that our laboratory as well as others have developed for the study of GBM. The concept of cancer stem cells in GBM and their potential therapeutic importance will also be discussed.

  • The cyclic environmental conditions brought about by the 24 h rotation of the earth have allowed the evolution of endogenous circadian clocks that control the temporal alignment of behaviour and physiology, including the uptake and processing of nutrients. Both metabolic and circadian regulatory systems are built upon a complex feedback network connecting centres of the central nervous system and different peripheral tissues. Emerging evidence suggests that circadian clock function is closely linked to metabolic homeostasis and that rhythm disruption can contribute to the development of metabolic disease. At the same time, metabolic processes feed back into the circadian clock, affecting clock gene expression and timing of behaviour. In this review, we summarize the experimental evidence for this bimodal interaction, with a focus on the molecular mechanisms mediating this exchange, and outline the implications for clock-based and metabolic diseases.
