Several acyclonucleoside analogues of pyrimidine base and N$^1$-derivatives of 5-fluorouracil have been synthesized and evaluated for their biological effects. When tested with in vitro Lekemia L1210 cells, the 5-fluorouracil derivatives exhibited slightly higher antitumor activity than the parent 5-fluorouracil. When tested against Herpes Simplex Virus type 1 and type 2 cultured in the Vero cell, the 5-fluorouracil derivatives showed weak antiviral activity.

1-Dodecylazacycloheptan-2-one (Azone) is a new agent that enhances the percutaneous penetration of a number of different chemicals. BVDU and FEAU were evaluated for their potential efficacy in the treatment of cutaneous herpes simplex virus infections by in vitro studies through hairless mouse skin. This study demonstrates the value of penetration enhancing agent (Azone) and the need for a predictable evaluations in the development of topical antiviral agents.

Herpes simplex virus type 2 (HSV2) meningitis primarily develops during or following a primary genital HSV2 infection that was acquired from sexual contact or through the birth canal during delivery from mother. We describe a 15 year old virgin without history of previous herpes simplex infection who developed 2 episodes of HSV2 meningitis. Although recurrent meningitis due to HSV is primarily seen in young or sexually active adults. HSV2 meningitis should be in the differential diagnosis of recurrent meningitis in adolescent patients.

A 59-year old man was admitted for drowsiness and stiff neck. CSF examination showed lymphocytic pleocytosis and PCR for herpes simplex virus (HSV)-1 was positive in CSF. Brain MRI revealed enhanced lesions in left temporal lobe. His symptom improved with acyclovir. Follow-up studies showed red blood cells in CSF and a hematoma in the left temporal lobe. There was no additional symptom related to the hematoma. He was discharged after conservative care. Although rare, hematoma can develop in HSV-1 meningoencephalitis.

A mutant herpes simplex virus 1, mtHSV, was constructed by inserting the E. coli beta-galactosidase gene into the loci of icp34.5, the apoptosis-inhibiting gene of HSV. The mtHSV replicated in and lysed U251 (human glioma cells), EJ (human bladder cells), and S-180 (mice sarcoma cells), but not Wish (human amnion cells) cells. With its intact tk (thymidine kinase) gene, mtHSV exhibited susceptibility to acyclovir (ACV), which provided an approach to control viral replication. An in vivo test with mtHSV was conducted in immune-competent mice bearing sarcoma S-180 tumors, which were treated with a single intratumoral injection of mtHSV or PBS. Tumor dimensions then were measured at serial time points, and the tumor volumes were calculated. Sarcoma growth was significantly inhibited with prolonged time and reduced tumor volume. There was microscopic evidence of necrosis of tumors in treated mice, whereas no damage was found in other organs. Immunohistochemical staining revealed that virus replication was exclusively confined to the treated tumor cells. HSV-1 DNA was detected in tumors, but not in the other organs by a polymerase chain reaction analysis. From these experiments, we concluded that mtHSV should be a safe and promising oncolytic agent for cancer treatment.

저자들은 헤르페스 잇몸입안염을 앓던 3세 소아에서 분비물이 동반된 손끝 염증소견을 보여 처음에는 세균성 손톱주위염으로 생각되었으나 이후 세균이 중복감염된 헤르페스 손끝염으로 진단되었던 1례를 경험하여 문헌 고찰과 함께 보고하는 바이다.

Benzopyrene (BP), 7,12-dimehyl benzanthracene (DMBA), nitrosomethyl urea (NUMU) 및 nicotine과 같은 발암성 화학물질들이 바이러스 감염된 vero 세포의 단층 세포 배양에서 I형 단순성포진 바이러스 (HSV-1)의 복제, 세포융해, DNA합성 및 단백질 합성에 미치는 효과를 관찰하였다. 1. BP와 DMBA는 HSV-1의 복제와 세포융해작용을 유의성있게 억제하였으나 nicotine과 NMU는 별로 억제하지 않았다. 2. 모든 발암성 화학물질은 바이러스의 DNA합성을 억제하지 못하였지만 새로 합성되는 후손바이러스 DNA로 부터 표현되는 gamma 단백질의 표현은 BP와 DMBA에 의해서 현저하게 억제되었다. 그러나 모든 발암성 화학물질은 바이러스의 alpha 및 beta 단백질의 합성은 억제하지 못하였다. 이상의 결과로 보아 발암성화학물질이 존재하고 있는 배지내에서 새로 합성되는 바이러스의 DNA로 부터 표현되는 gamma 단백질의 결함이 있음을 알 수가 있었으며 이같은 개념은 발암화학물질의 존재하에서 바이러스의 DNA와 단백질이 거의 정상적으로 합성됨에도 불구하고 바이러스의 복제가 일어나지 않는다는 사실이 뒷받침해주고 있다.

In order to explore the potential of ascorbic acid supplementation for the prevention and treatment of herpes simplex viral diseases, plaque reduction assays were performed. Ascorbic acid as well as copper chloride/ferric chloride were added to wells containing Vero cells infected with herpes simplex virus type 1 (HSV-1), and the infectivity of HSV-1 was determined. Since copper and iron are major transition metals in human plasma, near the normal human plasma concentrations of them were used for experiments. When Cu(II) and Fe(III) were applied, there were no significant differences between virus control and Cu(II)/Fe(III)-treated groups. But, when appropriate concentrations of ascorbic acid were added to wells, meaningful differences between control and ascorbate-treated groups were found. In the presence of Cu(II)/Fe(III) at $5.8/3.7\;{\mu}M$, 72-h treatment with ascorbate at $50\;{\mu}M$ reduced HSV-1 infections to $10.77%{\pm}4.25%$ (P < 0.001) and $500\;{\mu}M$ did to $3.06%{\pm}1.62%$ (P < 0.001). Moreover, the cytotoxicities for Vero cells at those concentrations were insignificant (P > 0.05). Current recommended dietary allowance (RDA) of ascorbic acid is 60 mg/day, and the oral intake of 60 mg/day of ascorbic acid yields plasma ascorbic acid at 45 to $58\;{\mu}M$ in a healthy adult man. Therefore, the results of this study suggest that the maintenance of appropriate level (more than $50\;{\mu}M$) of ascorbic acid in human plasma by appropriate amount (more than the RDA) of ascorbic acid supplementation may be helpful for the prevention and treatment of diseases caused by HSV -1 in an adult man. In addition, this study also suggests that ascorbic acid may be useful for the prophylaxis of fatal HSV-1 infections in neonates and the prevention of HSV-1 reactivation in immunocompromised hosts.

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.

유방에서 발생하는 헤르페스 감염은 매우 드물며 영상 소견 또한 잘 알려져 있지 않다. 본 증례 보고는 사춘기 여성 환자에서 발생한 헤르페스 유선염의 증례로 임상 소견 및 초음파 영상 소견을 기술하였다. B-mode 초음파에서는 일측성의 유륜 피부 두께 증가 및 액와부 림프절 종대의 소견을 보였고 도플러 초음파 상에서는 분지하는 양상의 선형 혈류 증대가 관찰되었다. 유륜 피부 생검을 통하여 헤르페스 감염으로 확진되었다. 헤르페스 유선염의 영상 소견은 국소적인 유두와 유륜 피부 비후와 혈류 증가로 유방의 Paget 병과 유사할 수 있으므로 감별이 필요하다.
