  • 결절성경화증은 유전성 신경피부 증후군으로 피부, 뇌, 신장 등의 여러 장기에 과오종을 형성하는 질환이다. 결절성경화증의 폐 침범은 드물지만 다발성 미세결절의 소견을 보이는 경우, 정확한 진단을 위해서는 고해상 흉부 전산화 단층 촬영 및 조직 검사가 필요하겠으며, 다발성 미세결절폐세포증식증을 감별 진단으로 고려해야 할 것이다. 이 질환의 임상적 의의 등 아직 알려진 것이 많지 않으나 현재까지의 보고로는 특별한 치료는 없으며 예후는 좋은 것으로 알려져 있다.

  • 인간 내인성 레트로 바이러스는 약 3~4 천만 년 전 인간게놈에 통합되기 시작했던 화석바이러스로서 인간게놈의 약 8%를 구성하고 있다. 이러한 고대의 레트로 바이러스는 연속된 유전자변이로 인해 본래의 기능을 잃게 됨으로써 "쓸모없는 DNA (junk DNA)"로 여겨져 왔다. 그러나 최근 연구는 모든 인간 내인성 레트로 바이러스가 단지 침묵을 지키는 승객만이 아님을 보여준다. 현재까지는 이들 바이러스가 인간 질병의 직접 원인이 된다는 것은 밝혀지지 않았으나, 다발성 경화증, 정신 분열증 및 근 위축성 측삭경화증을 포함한 신경학적 장애와 인간면 역결핍바이러스 (HIV)나 헤르페스 등의 바이러스 감염, 여러 유형의 암과 같은 질환을 가진 환자에서 인간 내인성 레트로 바이러스의 DNA가 과도발현 됨을 보여주는 연구들이 다양하게 이루어지고 있다. 이 리뷰논문은 신경학적 질환에 대한 인간 내인성 레트로 바이러스의 가능한 관련여부를 다루고 있다.

  • Minocycline is known to protect neurons from microglia-mediated cell death in many experimental models of brain diseases including ischemic stroke, Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), traumatic brain injury, multiple sclerosis, and Parkinson's disease. Activation of caspase-2, 3, 8, and 9 was evident within 2-8 hr following oxidative insult with 0.5 mM hydrogen peroxide in PC12 cells. Minocycline significantly attenuated activation of these caspases up to 18 hr, resulting a significant increase in cell viability as assessed by MTT assay. (omitted)

  • Multiple Sclerosis(MS) is an acquired, demyelinating disease of the central nervous system. Clinically, it is characterized by episodes of focal disorder of the optic nerves, spinal cord, and brain, which remit to varying extent and recur over a period of many years. The average age at diagnosis is 30, typically starting between the ages of 15 and 50. Women are affected at least twice as often as men. It is more common in persons of northern European heritage and those living furthest from the equator. The diagnosis of MS is based on a history of multiple attacks of neurologic lesions over time that affect different parts of the central nervous system. A case of MS was confronted. The patient was treated with Cheongsimyonjaum-gami(淸心蓮字飮加味), YangMyung channel(陽明) and had significant improvement was seen.

  • Tuberous sclerosis complex (TSC) is a genetic multisystem disorder that results from mutations in the TSC1 or TSC2 genes, and is associated with hamartomas in several organs, including subependymal giant cell tumors. The neurological manifestations of TSC are particularly challenging and include infantile spasms, intractable epilepsy, cognitive disabilities, and autism. The TSC1- and TSC2-encoded proteins modulate cell function via the mammalian target of rapamycin (mTOR) signaling cascade, and are key factors in the regulation of cell growth and proliferation. The mTOR pathway provides an intersection for an intricate network of protein cascades that respond to cellular nutrition, energy levels, and growth factor stimulation. In the brain, TSC1 and TSC2 have been implicated in cell body size, dendritic arborization, axonal outgrowth and targeting, neuronal migration, cortical lamination, and spine formation. The mTOR pathway represents a logical candidate for drug targeting, because mTOR regulates multiple cellular functions that may contribute to epileptogenesis, including protein synthesis, cell growth and proliferation, and synaptic plasticity. Antagonism of the mTOR pathway with rapamycin and related compounds may provide new therapeutic options for TSC patients.

  • 심장의 원발성 종양은 소아에서는 매우 드문 질환이다. 횡문근종은 태아, 영아 및 소아 연령에서 가장 흔한 원발성 심장 종양으로 결절성 경화증이 동반되는 것으로 보고되고 있다. 결절성 경화증은 뇌, 심장, 피부 및 기타 장기들을 침범하는 신경피부 증후군으로, 결절성 경화증을 가진 영아의 50-64%에서 동반된다. 심장 횡문근종은 종괴는 심방을 비롯하여 심실 중격과 심실벽에 다발성으로 존재하며 종양의 위치와 크기, 침범 정도에 따라 심장 유출로 협착 및 심부전과 같은 여러 가지 임상 양상을 보일 수 있다. 드물지만 부정맥을 주증상으로 발현하는 경우도 보고되고 있다. 하지만 대부분 심장의 횡문근종이 특별한 문제를 일으키지 않고 성장과 함께 쇠퇴되는 경향을 보이므로 극히 일부분에서만 장기적인 항부정맥제 사용이 요구된다. 환자의 최종적인 예후는 동반되는 뇌병변에 의해 결정되는 경향이 있다. 저자들은 상심실성 빈맥으로 입원치료 중 진단된 심장 횡문근종을 가진 결절성 경화증 1예를 경험하였기에 보고하는 바이다.

  • Panax ginseng Meyer (P. ginseng; Korean ginseng) is well known for its medicinal properties. It can alleviate pathological symptoms, promote health, and prevent potential diseases via its anti-inflammatory, antioxidant, homeostatic, and other positive effects on biological metabolism. Although many studies have determined effects of P. ginseng on various diseases, such as cardiovascular, neurological, and immunological diseases, little is known about the effect of P. ginseng on autoimmune diseases. Here, we review a few reports about effects of P. ginseng on autoimmune diseases (e.g., multiple sclerosis, Crohn's disease, ulcerative colitis, atopic dermatitis, and rheumatoid arthritis) and suggest the possibility of P. ginseng as a candidate herbal medicine to prevent and treat autoimmune diseases as well as the need to study it.

  • Acute disseminated encephalomyelitis (ADEM) is a demyelinating disease of the central nervous system (CNS) that typically presents as a monophasic disorder associated with multifocal neurologic symptoms and encephalopathy. ADEM is considered an autoimmune disorder that is triggered by an environmental stimulus in genetically susceptible individuals. The diagnosis of ADEM is based on clinical and radiological features. Most children with ADEM initially present with fever, meningeal signs, and acute encephalopathy. The level of consciousness ranges from lethargy to frank coma. Deep and subcortical white-matter lesions and gray-matter lesions such as thalami and basal ganglia on magnetic resonance imaging (MRI) are associated with ADEM. In a child who presents with signs of encephalitis, bacterial and viral meningitis or encephalitis must be ruled out. Sequential MRI is required to confirm the diagnosis of ADEM, as relapses with the appearance of new lesions on MRI may suggest either multiphasic ADEM or multiple sclerosis (MS). Pediatric MS, defined as onset of MS before the age of 16, is being increasingly recognized. MS is characterized by recurrent episodes of demyelination in the CNS separated in space and time. The McDonald criteria for diagnosis of MS include evidence from MRI and allow the clinician to make a diagnosis of clinically definite MS on the basis of the interval preceding the development of new white matter lesions, even in the absence of new clinical findings. The most important alternative diagnosis to MS is ADEM. At the initial presentation, the 2 disorders cannot be distinguished with certainty. Therefore, prolonged follow-up is needed to establish a diagnosis.

  • Background: The potential therapeutic values of Korean Red Ginseng extract (KRGE) in autoimmune disorders of nervous system have not been fully investigated. Methods: We used an acute experimental autoimmune encephalomyelitis animal model of multiple sclerosis and determined the effects and mechanism of KRGE on spinal myelination. Results: Pretreatment with KRGE (100 mg/kg, orally) for 10 days before immunization with myelin basic protein $(MBP)_{68-82}$ peptide exerted a protective effect against demyelination in the spinal cord, with inhibited recruitment and activation of immune cells including microglia, decreased mRNA expression of detrimental inflammatory mediators (interleukin-6, interferon-${\gamma}$, and cyclooxygenase-2), but increased mRNA expression of protective inflammatory mediators (insulin-like growth factor ${\beta}1$, transforming growth factor ${\beta}$, and vascular endothelial growth factor-1). These results were associated with significant downregulation of p38 mitogen-activated protein kinase and nuclear factor-${\kappa}B$ signaling pathways in microglia/macrophages, T cells, and astrocytes. Conclusion: Our findings suggest that KRGE alleviates spinal demyelination in acute experimental autoimmune encephalomyelitis through inhibiting the activation of the p38 mitogen-activated protein kinase/nuclear factor-${\kappa}B$ signaling pathway. Therefore, KRGE might be used as a new therapeutic for autoimmune disorders such as multiple sclerosis, although further investigation is needed.
