  • 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.

  • 신생아 HSV 감염은 주로 HSV type 2에 의해 발생하는 것으로 알려져 있으나, 국내에서는 신생아 HSV 감염의 역학 자료뿐만 아니라, HSV type 2가 증명된 신생아 수막뇌염 증례 보고조차 없었다. 저자들은 열과 경련을 주소로 내원한 생후 16일 신생아에서 PCR 검사를 통해 HSV type 2에 의한 수막뇌염을 진단하고 acyclovir 및 항경련제 치료를 시행하였다. 환자는 뇌 MRI 검사에서 뇌연화증이 있어 성장과 발달에 대해 추적 관찰 중이다. 우리나라 여성에서 30대에 HSV type 2 초감염이 가장 빈번히 발생하고 최근 평균 초산 연령이 증가하여 30대로 진입함에 따라 향후 HSV type 2에 의한 신생아 감염이 증가될 것으로 예상되어, HSV type2 감염은 열이 나는 신생아에서 반드시 고려해야 할 것이다.

  • 쥐의 배아의 척수신경절로 부터 슈반세포와 뉴런 세포가 각각 분리되어 배양되었다. in vitro 시스템에서 배양되었다. 정제된 뉴런 세포는 항 유사분열제로 처리하였고 정제한 슈반세포들과 함께 공동배양 하였다. 이 때 수초화 과정이 진행되었다. 이렇게 수초화된 공동 배양에 Herpes simplex virus-1을 감염시켜 탈수초화를 진행 시켰다. 우리는 수초화의 존재를 의미하는 neuropeptide Y의 항체를 이용하여 수초화와 탈수초화를 확인하였다.

  • Cholera toxin and dibutyryl cyclic adenosine 3', 5'-monophosphate(db-cAMP) increased the rate and number of infections units produced in the in vitro reactivation of latent herpes simplex virus, whereas adenosine diminished them. cAMP concentration in latently infected trigeminal ganglia of mice was greatly increased by cholera toxin but was not affected by adenosine.

  • An electron microscopic study was carried out on the morphogenesis of herpes simplex type 2 virus in BHK-21 cells BHK-21 cells was found susceptible to infection and replication of herpes simplex type 2 virus cytopathic effects of the herpes type appeared at approximately 1 day postinoculation. Foci consisting of rounded refractile cells and syncytia were observed. Projection of the nuclear membrane in the infected cells was also seen, Several infected cells showed a track-shaped structure which apparently consisted of multiple layered membranes of the nucleus.

  • For screening of the antiviral agent from soil, about 520 strains of microorganisms were evaluated for their antiviral activity, About 6.9% of strains showed more than 95% antiviral activity against Herpes Simples Virus (HSV)-1. Two strains among 30 strains active against HSV-1 virus showed a quite strong activity against human immunodeficiency virus.

  • Infections by herpes simplex viruses have an immense impact on humans, ranging from self-limiting, benign illness to serious, life-threatening diseases. While nucleoside analog drugs are available, resistance has been increasing and currently no vaccine exists. Ginsenosides derived from Panax ginseng have been documented to inhibit several viruses and bolster immune defenses. This study evaluated 12 of the most relevant ginsenosides from P. ginseng for toxicities and inhibition of herpes simplex viruses types 1 and 2 in Vero cells. The effects of test compounds and virus infection were determined using a PrestoBlue cell viability assay. Time course studies were also conducted to better understand at what points the virus life cycle was affected. Non-toxic concentrations of the ginsenosides were determined and ranged from 12.5 μM to greater than 100 μM. Ginsenoside 20(S)-Rg3 demonstrated the greatest inhibitory effect and was active against both HSV-1 and HSV-2 with an IC50 of approximately 35 μM. The most dramatic inhibition-over 100% compared to controls-occurred when the virus was exposed to 20(S)-Rg3 for 4 h prior to being added to cells. 20(S)-Rg3 holds promise as a potential chemotherapeutic agent against herpes simplex viruses and, when used together with valacyclovir, may prevent increased resistance to drugs.

  • Herpes simplex virus(HSV) infections of the CNS are associated with significant morbidity and mortality even when appropriate antiviral therapy is administered. HSV infections of the brain can be subdivided into two categories : neonatal HSV infections, which usually are caused by HSV type 2, and herpes simplex encephalitis(HSE), which occur in patients over 3 months old and is nearly uniformly caused by HSV type 1. The clinical presentation of HSE is one of the focal encephalopathic process associated with altered levels of consciousness, fever, focal seizures and hemiparesis. But because of the lack of pathognomic clinical presentation and diagnostic procedure, the efforts to develop alternative diagnostic procedure have led to the use of new diagnostic technique such as polymerase chain reaction(PCR). We report a case of HSV type 1 encephalitis in 13 month old male infant who presented with altered level of consciousness, fever and focal seizures. With the use of the PCR, HSV-1 DNA was detected in cerebrospinal fluid from the patient. The symptoms and signs of encephalitis subsided by treatment with acyclovir in 14 days.
