  • 본 연구는 뉴런 세포와 슈반 세포의 공동 배양에 의한 수초화 발생 과정과 herpes simplex virus-1 감염에 의한 탈수초화 발생과정을 전자 현미경과 분자생물학적 분석에 의하여 확인하고자 하였다. 쥐의 배아로부터 후근신경절(dorsal root ganglion, DRG)을 분리하여 슈반(Schwann) 세포와 뉴런 세포(neuronal cell)를 in vitro에서 각각 배양하였다. 유사 분열 억제인자로 처리한 뉴런세포와 정제된 슈반세포를 함께 공동 배양을 하여 수초화를 발생시켰다. 이렇게 수초화된 공동 배양 세포에 herpes simplex virus-1를 감염시켜 탈수초화를 진행시켰다. 수초 형성의 존재를 의미하는 myelin protein zero(MPZ) 항체를 사용하고 전자 현미경을 이용하여 수초 발생 및 탈수초화 과정을 관찰하였다.

  • 4-carbon fatty acid인 n-Butyrate(n-BTA)는 herpes virus의 일종인 Epstein-Bat virus(EBV)에 작용해서 잠복형인 EBV를 활성형태로 유도시키는 것으로 알려져 있다. 고로 본 실험에서는 mouse의 삼차신경절에 잠복하고 있는 HSV의 재활성화에 대한 n-BTA의 효과를 실험 관찰하였다. Pentobarbital로 마취시킨 mouse의 양쪽눈 각막을 30 gauge 주사바늘로 scarify한 후에 type I HSV(HSV-1) $10{\mu}1(1{\times}10^5$ plaque-forming units)를 각각 점안 감염시켰다. virus를 감염시킨 4주 후에 mouse의 삼차신경절을 적출하여 시험관 내에서 조직배양을 시행하였다. 조직배양시에 0. 1, 0. 25, 0.5. 1.0 그리고 2.0mM농도의 n-BTA를 첨가하였으며 1일, 2일, 3일간 각각 배양한 후 신경절을 연마하여 연마액내의 HSV-1 titer를Vero cell monolayer에서 plaque assay로 측정하였다. 1) n-BTA첨가군은 잠재성 HSV가 대조군에 비하여 현저하게 빨리 재활성화 되었고 재활성화되는 virus의 양도 현저히 증가되었다. 2) 24시간을 계속해서 n-BTA 각 농도를 첨가해서 배양할 군은 n-BTA 6시간 첨가 배양하고 새로운 배양액으로 갈아서 18시간 배양한 군에 비해 잠재성 virus의 재활성화가 현저히 증가되었다. 3) Gang1ionic latent HSV-1의 재 활성화에 영향을 미치는 각 농도의 n-BTA는 Vero cell의 monolayer에서의 HSV-1의 번식에는 아무런 영향을 미치지 않았다.

  • Wolf's isotopic response is defined as the occurrence of a new skin disorder at the site of another unrelated skin disease that has already healed. In most cases of isotopic response, the initial dermatosis is herpes infection, and the most frequent second dermatoses are granulomatous reactions. Various interpretations of this phenomenon have been attempted. However, the exact mechanism has not been identified yet. Herein, we report a case in which the secondary disease was segmental vitiligo that appeared over the same dermatomes of herpes zoster. A 71-year-old woman presented with well-defined, depigmented patches on the left chest and back. She had been diagnosed with herpes zoster on the same dermatomes and treated with an antiviral agent 3 years ago. Histological examination showed decreased basal melanin pigments and melanocytes. Consequently, the patient was diagnosed with segmental vitiligo based on the clinical and histological findings.

  • Objectives : This study aims to evaluate the effectiveness of incisional needle therapy, a type of Korean medicine treatment, on atrophic scars caused by herpes zoster and varicella. Methods : The patients with atrophic scars resulting from herpes zoster and varicella were treated with incisional needle therapy and the effectiveness of the treatment was evaluated with Physician's Global Assessment (PGA) and The Stony Brook Scar Evaluation Score (SBSES). Results : After treatment, all patients demonstrated improvements in PGA and SBSES. The PGA score improved to 3.73±0.40, with SBSES changing from 1.60±0.60 to 4.80±0.80. Conclusions : We suggest that incisional needle therapy demonstrates effectiveness in treating scars resulting from herpes zoster and varicella, indicating its potential as a viable therapeutic option for individuals affected by these conditions.

  • Shingles is a latent viral infection of the sensory ganglia. It can be accompanied by a variety of neurologic complications, including polyradiculitis and myelitis. A 66-year-old man with diabetes mellitus presented with progressive weakness, hypethesia and neuralgic pain in his right arm after herpes zoster infection in right C5 dermatome. He was diagnosed with zoster polyradiculomyelitis and treated with intravenous acyclovir and corticosteroid. It is a rare case of zoster neurologic complication in spite of oral acyclovir treatment.

  • Herpes simplex encephalitis (HSE) is one of the fulminant necrotizing, often fatal sporadic form of the encephalitis caused by herpes simplex type I virus. Characteristically, there is early and almost constant involvement of one or both temporal lobes, although there are common additional areas of involvement. Appropriate early treatment following correct diagnosis by clinical findings, CSF study, EEG and several radiological studies including angiography, redionuclide studies, CT or MRI can reduce its mortality and severity of the sequelae. We report a case of HSE diagnosed by adjuvant study of $^{99m}Tc-HMPAO$ regional cerebral blood flow SPECT, which showed a marked increase in bitemporal cerebral blood flow in a 24-year-old man.

  • Herpes zoster is an infection by the varicella zoster virus in a partly immune compromised person such as old age, cancer, immune deficiency disease. When either the upper lumbar or sacral segments are involved, serious urinary retention caused by central spread of herpes zoster from dorsal root ganglion can occur. The urinary disturbance appears to have been due to motor dysfunction of detrusor muscle, trigone muscle, and internal sphincter. We experienced two cases of zoster affecting different segments of the spinal cord and resulting in urinary retention.

  • We report a case of 70-year-old man with glioblastoma presenting as acute encephalitic illness. The patient exhibited sudden onset of cognitive impairment and headache for 2 days. Initial brain MRI showed left temporal lobe hyperintensity, and cerebrospinal fluid cytology revealed a mild pleocytosis. The patient had initially improved after medical treatment with a presumptive diagnosis of herpes simplex encephalitis (HSE). After 8 months, the patient complained of recurrent seizures. A follow-up brain MRI revealed marked increases in size and surrounding perilesional edema in the left temporal lesion on T2-weighted images and a new contrast-enhancing lesion on gadolinium-enhanced T1-weighted images. Stereotactic brain biopsy revealed a glioblastoma. The atypical encephalitic presentation of glioblastoma should be considered if definitive evidence for the diagnosis of HSE cannot be obtained.

  • Varicella, which is mostly a benign disease, but also can cause considerable health burden in the community, can be prevented by immunization with live attenuated varicella vaccine. Higher uptake of varicella vaccine by universal immunization in North America has apparently been associated with decline in the number of reported cases of varicella, varicella-related hospitalizations, and the number of deaths caused by complications of varicella. On the contrary, there has been some reluctance in endorsing varicella vaccine for universal immunization in most of European countries. Concerns include unanticipated outbreaks of varicella among vaccine recipients, risk of varicella among unvaccinated adults, risk of herpes zoster among vaccinees as well as unvaccinees. Recently developed measles, mumps, rubella, and varicella combination vaccine and herpes zoster vaccine that may be licensed in the upcoming years may be the solution for varicella vaccine to be utilized in a greater scale. In Korea several varicella vaccine products have been utilized since late 1980. The adoption of varicella vaccine for universal immunization since 2005 along with the changing view in varicella prevention strategy mandates more studies for immunogenecity and efficacy of varicella vaccines as well as more surveillance to delineate the changes in epidemiology of varicella in Korea.
