efficacy of topical acyclovir monophosphate, acyclovir, or penciclovir in orofacial hsv-1 infections of mice and genital hsv-2 infections of guinea pigs.the purpose of these studies was to compare the efficacy of acyclovir monophosphate (acvmp), acyclovir (acv), or penciclovir (pcv) against hsv-1 in an orofacial infection of mice and against acv sensitive and resistant genital hsv-2 infections of guinea pigs. treatment was initiated 24, 48, or 72 hours post inoculation with 5% acvmp, 5% acv (zovirax) or 1% pcv (denavir). in all experiments, similar efficacy was obtained for acvmp and acv, whereas pcv was considerably less effective.200010772730
[the functions of alpha herpesvirus gene products].herpes simplex virus type 1(hsv-1), type 2(hsv-2) and varicella-zoster virus (vzv) belong to alphaherpesvirus family. these herpesviruses have large dna genomes which contain at least 69 genes. these viral genes are divided into two groups based on whether they are essential or dispensable for virus growth in cell culture. the essential gene products include transcriptional factor, viral dna replication, dna cleavage/packaging and virion components, while the dispensable gene products include de ...200010774196
[seroepidemiology of alphaherpesviruses].the seroepidemiology of herpes simplex virus (hsv) type-1 and -2 was studied in different japanese populations, by applying hsv gg1 and gg2 type-specific antibody assays. hsv-1 infections correlated mostly with age and was widely prevalent among subjects over 40 years old. hsv-2 prevalence varied greatly among subgroups defined by sexual activity and were associated with risk behaviors, from 80% among prostitutes to 7% among pregnant women. since hsv-1 infection during childhood has been decreas ...200010774202
[alpha-herpesvirus infection in the central nervous system].herpes simplex virus type 1 (hsv1) encephalitis is commonly observed, but hsv1 myelitis is rare. on the other hand, hsv2 is common etiologic agent for ascending necrotizing myelitis associated with diabetes mellitus, malignant tumors, aids and immunocompromised hosts. it is suggested that latent infection of the virus of root ganglia or primary infected virus is possibly followed by spread of infection to the central nervous system, particularly in immunocompromised patients. in this report, pat ...200010774207
[alpha-herpes virus infections--male genital herpes].in japan, male genital herpes is the third popular male std, the most popular one being gonococcal infection and the second chlamydial infection. as specific clinical findings, superficial ulcer lesions with pain are formed in the genital area, especially in the prepuce. after hsv infection in genital mucocutaneous sites, viral particles are transported to the neurons. the state of subsequent hsv infection from external genitalia to the neurons is known as latent infection. 76% of our cases of t ...200010774209
[sexually transmitted diseases of alpha herpes virus in women].among two alpha herpes viruses, herpes simplex virus(hsv) and varicella zoster virus(vzv), hsv infects genital sites and is frequently transmitted by sexual contact while vzv has quite different mode of transmission and rarely infects genital site except herpes zoster at the vulva. genital herpes is the second and the third leading cause of stds in women and men respectively. while 90% of male genital herpes was caused by hsv-2, 55% of female genital herpes was by hsv-2 and the remaining 45% by ...200010774210
[ophthalmic area].although herpes simplex virus type 1 or herpes zoster virus is generally considered to cause ocular infection among alpha herpesviruses, herpes simplex virus type 2(hsv-2) retinitis has been recently reported. acute retinal necrosis(arn) syndrome is associated with herpesviruses, but the mechanisms remain unclear. the representative ocular infection by alpha herpesviruses is herpes simplex virus type 1(hsv-1) keratitis. the clinical types, ocular symptoms and therapy are reviewed in herpetic ocu ...200010774213
risk factors for pre-cancerous lesions of the cervix.studies on risk factors for pre-cancerous lesions of the uterine cervix have shown strong association with sexual practice. women with multiple sexual partners and intercourse at early age are at high risk. a role of male partners in further enhancing the risk has been identified. all these support the hypothesis relating to a sexually transmissible aetiological agent. an extensive review of the literature on the risk factors for pre-cancerous lesions of cervix has been carried out. the risk fac ...200010777005
synthesis of 4'-substituted nucleosides and their biological evaluation.4'-c-ethynyl-beta-d-arabino- and 4'-c-ethynyl-beta-d-2'-deoxy-ribo-pentofuranosyl pyrimidines were synthesized. most of these 4'-ethynyl nucleosides showed interesting biological activities.199910780412
fast and type-specific analysis of herpes simplex virus types 1 and 2 by rapid pcr and fluorescence melting-curve-analysis.diagnosis of central nervous system (cns) infection with herpes simplex virus (hsv) requires sensitive and rapid techniques. pcr therefore is considered to be the diagnostic gold standard in these cases. however, current pcr protocols are time-consuming and labor-intensive. in addition, the need for post-amplification manipulations increases the risk of laboratory contaminations with amplified products. in order to improve conventional pcr techniques we compared our current semiautomated hsv-pcr ...200010782393
