  • 중추신경계의 침범을 동반한 Epstein-Barr 바이러스 관련 혈구포식 림프조직구증은 조혈모세포이식을 시행하지 않으면 예후가 좋지 않다. 또한, 고식적인 강도의 전처치시 이식관련 사망률이 높다. 따라서 저자들은 진행성 중추신경계 침범을 보인 Epstein-Barr 바이러스 관련 혈구포식 림프조직구증 2례에서 저강도 전처치와 rituximab 후 타인 조혈모세포이식을 시행하여 치료하였기에 이를 보고하고자 한다.

  • A flaccid tetraparesis in Bickerstaff's brainstem encephalitis (BBE) is presumed to be a sign of overlapping Guillain-Barr$\acute{e}$ syndrome (GBS). In addition, BBE and Fisher syndrome, which are clinically similar and are both associated with the presence of the immunoglobulin G anti-GQ1b antibody, represent a specific autoimmune disease with a wide spectrum of symptoms that include ophthalmoplegia and ataxia. A 2-year-old boy presented with rapidly progressive ophthalmoplegia, ataxia, hyporeflexia, weakness of the lower extremities, and, subsequently, disturbance of consciousness. He experienced bronchitis with watery diarrhea and had laboratory evidence of recent infection with Epstein-Barr virus (EBV). He was diagnosed as having overlapping GBS and BBE associated with EBV and received treatment with a combination of immunoglobulin and methylprednisolone, as well as acyclovir, and had recovered completely after 3 months. In addition, he has not experienced any relapse over the past year. We suggest that combinations of symptoms and signs of central lesions (disturbance of consciousness) and peripheral lesions (ophthalmoplegia, facial weakness, limb weakness, and areflexia) are supportive of a diagnosis of overlapping GBS and BBE and can be helpful in achieving an early diagnosis, as well as for the administration of appropriate treatments.

  • The results of this study intended to clarify the apoptotic effects of curcumin on Epstein-Barr virus transformed human B lymphoma (EBV-B) cells are summarized as follows: It was found that curcumin induced endoplasmic reticulum(ER) stress as well as apoptotic cell death in EBV-B cells, although the magnitude of action was insignificant. When EBV-B cells activated by pokeweed mitogen (PWM) were treated with the same concentrations of curcumin, it was found that higher ER stress (GRP78, P-PERK, XBP-1, ATF6, and CHOP expressed) increased unfold protein response (UPR) and thus, apoptosis attributed to ER stress, compared to non-activated EBV-B cells In conclusion, it is expected that curcumin will play an important role for leukemia treatment.

  • Hydroa vacciniforme (HV) is a disease of Epstein-Barr virus (EBV)-associated NK/T cell lymphoproliferative disorder, and patients with severe HV-like eruptions have a high risk to progress to various EBV-related hematological complications. Photosensitivity in HV might be a 'photo-Koebner' phenomenon mediated by infiltration of EBV-infected NK/T cells.

  • Betulin, a pentacyclic triterpenoid isolated from the bark of Betula papyrifera. Laboratory synthesized structural analogs were tested for antiviral activities against Epstein-Barr Virus (EBV) by immunofluorescent antiviral assay. Among the several analogs tested, betulin 3,28-diphosphate and uvaol exhibited significant antiviral activities against EBV. The $EC_{50}$ of betulin 3,28-diphosphate and uvaol was found to be $0.6\mu{M}$ and $0.7\mu{M}$ respectively.

  • Cholelithiasis and choledocholithiasis are uncommon pediatric diseases, although clinicians have seen them with increasing frequency in children in recent years. Moreover, no case of Epstein-Barr virus (EBV) infection with cholelithiasis and choledocholithiasis has been previously reported in the English literature. We report a pediatric patient with EBV infection, a gall bladder stone, and a common bile duct stone, may have had GB and CBD stones prior to her EBV infection, whom we successfully treated with antibiotics and laparoscopic cholecystectomy for cholecystitis.

  • Infectious mononucleosis is Epstein-Barr virus (EBV) inducing a self-limiting clinical syndrome characterized by fever, sore throat, hepatosplenomegaly, and generalized lymphadenopathy. Gastrointestinal symptoms of EBV infection are nonspecific and occur rarely. EBV inducing acute gastrointestinal pathology is poorly recognized without suspicion. Careful consideration is needed to diagnose gastric involvement of EBV infection including gastric lymphoma, gastric cancer, and gastritis. A few recent cases of gastritis associated with EBV infection have been reported in adolescents and adults. However, there is no report of EBV-associated gastritis in early childhood. We experienced a rare case of 4-year-old girl with EBV gastritis confirmed by in situ hybridization.

  • Epstein-Barr virus (EBV), cytomegalovirus (CMV), hepatitis B virus (HBV), parvovirus B19 (B19)등 4종의 바이러스는 인체에 감염을 일으키는 병원체로서 DNA를 유전물질로 함유한다. 각 바이러스 유전자의 염기서열을 분석하여 EBV CMV, HBV의 pol 유전자와 B19의 ns 유전자에 특이적으로 결합할 수 있는 primer를 설계 제작하고 단일 시험으로 4종의 바이러스를 동시에 검출할 수 있는 다중 중합효소 연쇄반응(Multiplex PCR)법을 확립하였다. Primer 염기서열, PCR 반응조성물의 농도, PCR 반응시간 및 온도조건을 최적화하여 민감도를 증대시킴으로써, 단일 시험으로 5-10 분자수의 유전물질까지 검출이 가능하였다. 또한 4종의 바이러스 사이에 교차반응이 일어나지 않았으며 생체시료를 이용한 시험에서도 특이성과 민감도가 유지됨을 확인하였다. 그러므로 본 연구에서 확립한 다중 중합효소 연쇄반응은 세포배양액 또는 생체 시료에 감염된 4종 DNA 바이러스진단에 효율적으로 이용할 수 있을 것이라고 판단된다.

  • Herpes virus family is highly infectious to patients, their families and dentists. The diagnosis of herpes infection is based on the characteristic clinical appearance and the location of the lesions. Herpes Simplex Virus(HSV) usually acquired through direct contact with infected lesions or body fluids, and the prevalence of HSV infection increases progressively from childhood. Primary infections provoke herpetic gingivostomatis typically affects the tongue, lips, gingival, buccal mucosa and palate. Recurrent infections give rise to vesiculo-ulcerative lesions at vermilion border of lip(herpes labialis). In the form of chickenpox, Varicella Zoster Virus(VZV) usually is infected in childhood. VZV spreads in the affected primary afferent nerve to the skin and produces a vesicular rash and pain. Epstein-Barr Virus(EBV) infects B cells and cause infectious mononucleosis. Latent EBV infection has also been implicated in Burkitt lymphoma, nasopharyngeal carcinoma. Cytomegalovirus(CMV) is associated with immune-compromised patient such as organ transplantation and AIDS patients.
