  • 목적: 유전자 치료에서, 종양세포에 herpes simplex virus thymidine kinase 유전자를 발현시키고 이에 민감한 prodrug을 전신투여하여 발현된 종양세포에 특이적으로 집적되는 방법은 매우 효율적인 방법이다. 대표적인 prodrug인, IVDU, IVFRU는 herpes simplex virus type 1의 비침습적 영상화 방법에 응용되는 방사옥소 표지가능 화합물이다. 재료 및 방법: Trans-l-trimethylsilyl-2-tri-n-butylstannylethylene과 uridine 변형체상의 iodo-uracil을 Pd촉매하에서 반응시켜 표지전구체인 5-trimethylvinyl-deoxy-uridine과 5-trimethylsilylvinyl-deoxy-fluororibofuranosyl uracil을 합성하였다. 이것을 column chromatography의 방법으로 분리 정제하였다. 합성한 각 전구체를 ICI 담체를 이용하여 높은 수율로 표지하였고, HPLC를 사용하여 분리하였다. Radiohalogen exchange 방법은 비방사능을 낮게 할수록 표지에 효율적으로 알려져 있다. 이 방법으로 ICI 방법을 사용하여 담체를 포함하는 높은 방사능의 화합물을 얻을 수 있다. 결과: IVDU와 IVFRU 표지를 위한 전구체 합성수율은 각각 43, 72% 였다. ICl로 담체를 이용한 표지방법을 사용하여 IVDU와 IVFRU 표지수율은 98% 이상이었다. 결론: HSV1-tk를 이용한 유전자 영상용 기질의 전구체를 성공적으로 합성하였고. 95% 이상의 높은 표지수율의 유전자 영상용 방사성 추적자를 성공적으로 제조하였다.

  • Herpes simplex virus, Varicella zoster virus and Human herpes virus-6 caused central nervous system infections and latent infections but there is no data of the 3 viruses being tested from the same cerebrospinal fluid samples with aseptic meningitis or encephalitis in adults patients. These viruses produced similar neurologic symptoms but difficulties existed in differentiating of etiologic agents and therefore the viruses needed to be detected in the early state. Herpes simplex virus encephalitis (HSVE) in adults, if not treated promptly was fatal. If treated with antiviral drugs in the early phase of encephalitis, neurologic sequales decreased by 65%. Recently, a PCR method for detection of HSVE with CSF was developed. VZV primary and secondary infections caused neurologic symptoms of encephalitis or meningitis. The second frequency of adult encephalitis that caused VZV were reported. HHV-6 caused CNS latent infection that was studied with normal adults brains. But there is no data of HSV, VZV and HHV-6 for aseptic meningitis and encephalitis of Korean adults through etiologic study. We cultured CSFs on HEp-2 cells and simultaneously tested for HSV PCR, VZV nested PCR and HHV-6 PCR with 8 specific primers. The PCR results of CSF from meningitis Korean adults were 13/19 (68.4%) for HSV, 10/19 (52.6%) for VZV and 12/19 (63.2%) for HHV-67/19 (36.8%) cases were triple infected HSV PCR, VZV PCR and HHV-6 PCR positive; 3/19 (15.8%) cases were dual infected HSV PCR and HHV-6 PCR positive; 1119 (0.5%) cases was VZV PCR positive. Strong viral DNA amplification of CSF means a causative virus may be present in aseptic meningitis or encephalitis patients and may cause clinical neurologic symptoms. HSV and HHV-6 viruses detection rate were higher than VZV by PCR with CSFs.

  • Objectives : The aim of this study is to report a case of a 51-year-old patient with Herpes zoster, whose symptoms were relieved within five weeks after the East-west medical combined treatment. Methods : A Herpes zoster patient with extreme pain around the right lower ribs and lower back was admitted into the Korean medicine hospital. Bee venom acupuncture was applied directly onto the site of pain and electroacupuncture was applied on $GV_6-BL_{20}$, inferior site of spinous process of the 12th thoracic vertebra-$BL_{21}$, $GV_5-BL_{22}$, $GV_4-BL_{23}$ six times a week. Moxibustion was applied on $BL_{49}$, $BL_{50}$, $BL_{51}$, $BL_{52}$, $GB_{25}$, $LR_{13}$ six times a week, and the patient took daily doses of herbal medicine and western medicines such as anticonvulsants, analgesics, antiepileptics. The patient's symptoms were evaluated with numeric rating scale(NRS) and neuropathic pain scale(NPS). Results : The results were as follows: 1. After the East-west medical combined treatment, the NRS grade decreased from 8 to 1. 2. On the neuropathic pain scale, the patient's symptoms changed from deep sharp pain and burning sensation to superficial dull pain and coldness. Sensitivity to touch, discomfort, and itchiness also decreased. Sudden attacks of pain appeared 14 to 21 days after onset, but disappeared after final treatment. Conclusions : The results of the above patient suggests that the East-west medical combined treatment may be effective for total remission of herpes zoster. Further research is needed to confirm such effects.

  • Two triterpenes 1 and 2 with antiviral activity against Herpes simplex virus type 1 in vitro were isolated from Prunella vulgaris. Each compound caused a significant reduction in viral cytopathic effect when vero cells were exposed to them for 72 hours after viral challenge. They were identified as betulinic acid (1) and $2\alpha, 3\alpha$-dihydroxyurs-12-en-28-oic acid(2) on the basis of their spectroscopic properties. The antiviral activity of them was estimated as $EC_{50}=30\;\mu$g/ml(1) and $8\;\mu$g/ml(2), respectively by plaque reduction assay.

  • Topical preparations such as cream for Acyclovir(ACV), a potent anti-viral agent for the treatment of herpes simplex and herpes zoster, have been marketed in the world since 1993. However, the skin penetration rate of ACV from generic cream formulations sold in Europe has been found to be lower than the original $Zovirax^{\circledR}$ cream. In this study, we formulated ACV into a novel organogel system and compared the skin penetration characteristics with $Zovirax^{\circledR}$ cream. The rate and amount of skin penetration of ACV from the organogels were 6.3-fold greater than those obtained with $Zovirax^{\circledR}$ at an ACV concentration of 5%. The solubilizing effect of oil phase and anti-nucleation effect exhibited by sodium alginate contained in water phase are most likely attributed to enhanced ACV skin penetration property.

  • Eczema herpeticum is a widespread Herpes simplex virus(HSV) infection, which usually develops in patients with atopic dermatitis, because prutitis in patients with atopic dermatits leads them to scratch their bodies, it cause the dissemination of Herpes simplex virus. This study carried out to observe the progress of Eczema herpeticum and find effective remedy. The pastient was taken Herb-medicine with acupunture, cupping theraphy, aroma theraphy, and etc. After the treatment the grade of VAS was decressed and clinical symptoms were gradually disappeared. Those results suggest that herbal treatment was effective to Eczema herpeticum.
