  • 신경초종은 비교적 드문 질환으로서1908년Verocay가 이 종양의 특징적 조직소견인 Verocay body를 발견하고 이를 neurinoma라고 명명하였다. 이 종양은 양성종양으로서 뇌신경, 척수신경뿐 아니라 자율신경에서도 발생하여, 약 25%가 두경부에서 발생하고, 단일 부위로서는 청신경에서의 발생빈도가 가장 높으나 인후부 발생은 드물다. 저자들은 피열후두개추벽에 발생한 거대한 신경초종 1례를 치험하였기에 보고하는 바이다.

  • 양성 신경초종(benign schwannoma)이 식도를 포함한 위장관계에 발생하는 경우는 매우 드물다. 이러한 양성식도 신경초종은 확진을 위해 면역 조직 화학적 염색을 필요로 한다. 정기 신체 검진상 우연히 발견된 66세여자 환자의 식도 점막하 종양에 대해 우측 후측부 개흉을 통한 종양 적출을 시행하였으며, 술후 면역 조직 화학적 병리 검사를 통하여 식도의 양성 신경초종임을 확인하였고, 환자는 술후 1년째 재발없이 외래 추적 관찰을 받고 있다.

  • Histologic and microstructural changes during the postembryonic development of the wolf spider Arctosa kwangreungensis were studied using light and scanning electron microscopy to examine the relationship between a morphological differentiation and behavioral properties. The postembryo with abdominal yolk sac was stayed inactive in the egg case because its muscular and visual systems were not fully developed to a functional level. The first instar spiderlings, developed from the postembryo by a first molting process, started to exhibit its pigmentation on their body cuticles. In particular, undifferentiated cell clusters of central nervous system (CNS) were densely distributed within the cephalothorax, and highly differentiated abdominal ganglion was observed. They had a characteristic visual system looks more like its adult counterpart, and had segmented appendages looks more like the tiny spiders containing well oriented muscular system. After 3rd instar, spiderlings grew more rapidly with accordance to their consistent growth and periodical molting processes. Thus, the relative area of CNS with respect to cephalothorax was gradually decreased, instead a pair of venom glands, musculature, and connectives occupied the residual area. It has been revealed that the early development of spider can be controled by the feeding condition of larval period, since histologic and microstructural differentiations in both appendages and optic system were completed at the second instar. In particular, behavioral properties of the wandering spiders that depend on vision and their running ability were deeply related to physiological differentiation of the microstructural development.

  • The authors reviewed and analyzed the pathologically confirmed 230 cases of benign soft tissue tumors which had been treated at Department of Orthopaedic Surgery in Seoul Hospital, Hanyang University College of Medicine from February 1984 to November 1997. The following results were obtained. 1. The most common benign soft tissue tumors was ganglion(26.5%) followed by hemangioma(19.6%), lipoma(17.0%), Baker's cyst(13.0%) and neurilemmoma(7.0%) in decreasing order of incidence. 2. Benign soft tissue tumors were found evenly distributed over all age group. Hemangioma and lymphangioma were usually found to occur before 20 years old. 3. Female was affected about 1.3 times more common. But, Baker's cyst and neurilemmoma occurred most frequently in male. 4. In children, the most common benign soft tissue tumors was hemangioma followed by ganglion, lymphangioma, and lipoma. In adult, ganglion, lipoma, Baker's cyst, hemangioma were common. 5. The lower extremity was the predominant site of occurrence(60.0%). 6. Benign soft tissue tumors were taken by excision. Local recurrences were developed in 22(9.6%) out of 230 cases, especially in hemangioma.

  • Tumors originated from peripheral nerve tissues are neurofibroma, neurilemoma, plexiform neurofibroma, malignant schwannoma, and granular cell tumor. Neurofibromas seem to occur in two forms : The first one is circumscribed solitary neurofibroma and the second group is neurofibromatosis or Von Recklinghausen's disease, which is a congenital and familial disease, presenting abnormalities of the skin, nerve system, bones and soft tissue. A solitary neurofibroma is a benign, relatively circumscribed, noncapsulated tumor which often presents in the skin and subcutaneous tissue as a soft sessile or pedunculated mass. It may occur anywhere in the head and neck, but the common site of the occurrence is the tongue, buccal mucosa, palate in frequency. Since solitary neurofibroma is a relatively radioresistant and its recurrence rate seem to be low, the treatment of choice is surgical excision. The author would like to present a case of unusually large solitary neurofibroma occured in the chin, which was successfully treated with surgical excision and reconstructed using deltopectoral flap and tongue flap.

  • 당뇨병을 장기간 앓게 되면 혈관이 분포한 모드 조직 또는 기관을 침범하는 임상 증후군이 발생하는데 이를 당뇨병의 만성 합병증이라고 부른다. 당뇨병 만성 합병증의 기본적인 병리생리는 혈관 질환이며 침범하는 장기와 혈관의 크기에 따라 다음과 같이 분류된다. 눈에 생기는 망막증, 신장에 생기는 신장병증, 신경 특히 말초신경에 발생하는 신경병증들은 미세혈관의 손상에 따라 발생하므로 미세혈관 합병증이라고 부르며 심장에 생기는 협심증, 뇌혈관 경색으로 대표되는 뇌졸중, 하지 동맥폐색증은 대혈관 합병증이라고 부른다.

  • 출생후 0일. 7일. 14일 및 21일 그리고 성체의 흰쥐 전뇌 기저부의 내측중격핵, 수직 및 수평 대각 Broca대 거대세포 시삭전핵 그리고 복부담창구에서 신경성장인자수용체 (nerv-growth 배ctor receptor, NGFr)에 면역반응을 보이는 신경조직과 세포의 분화를 면역조직화학적 및 전자현미경적 방법을 이용하여 조사하였다. 출생후 초기와 성체에서 신경세포 원형질막 뿐만 아니라 세포질에서 NGFr 면역반응이 확인되었다. 그러나 성체에서 신경세포 원형질 막에서의 면역반응은 관찰되지 않았다. 특히 NGFr 면역반응은 골지 부위에서 보였고, 점상의 면역반응물들이 세포체의 세포질과 수상돌기에 소수 분산 분포하였다. 뇌 기저부의 NGFr 면역반응 신경세포들은 뇌 크기의 증대와 뇌 조직의 분화에 따라 점차 수적 증가를 보였다. 이 NGFr 면역반응 신경세포들은 세포의 모양과 세포체의 장 .단축의 비에 따라 6가지 형. 즉 1) 원형. 2) 타원형. 3) 세장형, 4) 방추형, 5) 삼각형, 6) 다각형으로 분류되었다. 전뇌 기저 핵에서 원형과 난형신경세포들의 출현율은 출생후 0일에서 높았으나 성체로 되면서 감소된 반면, 세장형. 방추형, 삼각형 그리고 다각형신경세포들의 출현율은 출생후 0일에서는 낮았으나 성체로 되면서 증가하였다. 모든 핵들에서 NGFr 면역반응 신경세포체의 부피는 출생후 0일에 759-1,640 Um3로 제일 작았으며, 수직 대각 Broca대와 복부담창구에서는 출생후 14일에 각각 5 107 7.385 Um3 그리고 내측중격핵, 수평 대각 Broca대, 거대세포 시삭전핵에서는 출생후 21일에 각각 4,705, 6,061, 6,412 Um3로 최대치를 보였다. 그후 성체로 되면서 모든 핵에서 1,893-3,464 $\mu$m3로 다시 감소하였다. 전자현미경적 관찰에서 출생후 21일된 흰쥐 수평 대각 Broca대에서 NGFr 면역반응은 세포체와 수상돌기의 원형질막 그리고 세포체내에서는 골지체, 다소포성소체 및 조면소포체에서 관찰되었다. 이 결과들로 미루어 NGFr은 출생후 발생단계와 성체의 횐쥐 전뇌 기저부에서 신경세포의 분화와 분포에 관계되는 것으로 생각된다.

  • Spinal epidural lipomatosis, which causes symptomatic compression of neural elements, is a relatively uncommon disease. Although it has been reported frequently in association with the administration of exogenous steroids, a few cases of epidural lipomatosis with no association to exogenous steroids, have been reported. Idiopathic spinal epidural lipomatosis may be a separate disease from that induced by steroid. Here, the authors present two cases of symptomatic epidural lipomatosis with no history of steroid-dependent diseases and review the relevant literature.

  • Stress, a risk factor of major depression induces cytokine mediated inflammation and decreased neurogenesis. In patients with major depression, significant increases of pro-inflammatory cytokines have been consistently reported. The pro-inflammatory cytokines can stimulate the hypothalamic-pituitary-adrenal (HPA) axis to release glucocorticoids. In the brain, microglia and play a role of immune activation in response to stress. Increased pro-inflammatory cytokine play a role in restricting neurogenesis in the brain. Although neurogenesis may not be essential for the development of depression, it may be required for clinically effective antidepressant treatment. Hence, stimulation of neurogenesis is regarded as a promising strategy for new antidepressant targets. This review introduces changes in neurotransmitter, cytokine and neurogenesis in major depression and explores the possible relationship between pro-inflammatory cytokines and neurogenesis related to stress in major depression.
