oral acyclovir (zovirax) in herpes simplex dendritic corneal ulceration.sixty patients with simple dendritic corneal ulceration were randomly assigned to double blind treatment with either acyclovir tablets (400 mg) or acyclovir ophthalmic ointment administered five times daily. there was no significant difference in the proportions of patients healed in either treatment group (88.9% on oral acyclovir and 96.6% on acyclovir ointment). the median healing time was five days in both groups. no systemic or significant local side effects were noted in either treatment gr ...19863521717
adenovirus replication as an in vitro probe for drug sensitivity in human tumors.the feasibility of using adenovirus 5 as an in vitro probe for chemosensitivity in short-term cultures of human tumors was evaluated using human melanoma cell lines and primary cultures of melanoma biopsies. a convenient immunoperoxidase method was developed for quantitating viral replication 2 days after infection. two different approaches were explored: the host cell reactivation assay (hcr) using drug-treated virus; and the viral capacity assay using drug-treated cells. the hcr assay detected ...19863525182
synthesis of fused glycoprotein d of herpes simplex virus type 1 but not type 2 inhibits escherichia coli hosts.glycoprotein d from either herpes simplex virus type 1 (gd-1) or type 2 (gd-2) has been expressed in escherichia coli as a series of chimeric proteins. the expression vector used in this study, pjs413, was derived from pbr322 and contains several cloning sites between the lacz promoter-operator and the phage lambda cro gene. plasmids containing fusions between the cro gene, gd-related sequences and lacz was constructed and shown to direct the synthesis of 160-kda proteins. the accumulation of fu ...19863527874
detection of viral antigens in cerebrospinal fluid of rabbits with experimental herpes simplex virus type 1 encephalitis.we investigated several methods for the rapid diagnosis of herpes simplex virus induced encephalitis in a rabbit model. the corneas of twenty-two rabbits were infected with herpes simplex virus type 1 (hsv-1) and diagnosis of herpes encephalitis was made by virus isolation, immunofluorescent and peroxidase staining of brain biopsies, demonstration of anti-hsv igm in cerebrospinal fluid (csf) and by an indirect enzyme-linked immunosorbent assay (elisa), designed for detection of viral antigens. w ...19863530193
combined antiviral effects of acyclovir or bromovinyldeoxyuridine and human immunoglobulin in herpes simplex virus-infected mice.suboptimal dosage regimens of antivirals (acyclovir or bromovinyldeoxyuridine) and human immunoglobulin have been combined in the treatment of hairless mice infected with herpes simplex virus type 1. the aim of this study was to establish how late after infection human immunoglobulin could be given to still be effective and for how long would the protective effect last. the combination of acyclovir or bromovinyldeoxyuridine with passive immunization proved additive or even synergistic depending ...19873619435
effects of acyclovir therapy during simultaneous reactivation of latent hsv-1 in rabbits.acyclovir (acv) therapy with a simultaneous reactivation of latent hsv-1 was evaluated in hsv-1 infected rabbit eyes. when the latently infected rabbits received epinephrine iontophoresis into corneas without acv therapy 100% of eyes shed virus into tear film. the shedding was initiated on the second day of the epinephrine iontophoresis and lasted for an average of 4.6 days. when the rabbits received acv (60 mg/kg body weight) intravenously once daily and topically (5% acv ointment) twice daily ...19873619436
recurrent herpes simplex virus type 1 corneal epithelial lesions after radial keratotomy in the rabbit.the effects of radial keratotomy (rk) on herpes simplex virus type 1 ocular shedding and recurrent corneal epithelial lesions were assessed for 14 days after rk in rabbits latently infected with strain mckrae. ten latently infected rabbits had rk performed on the right eye. the left eye was used as the control. viral shedding was monitored by ocular tear-film swabs. the recurrent lesions were monitored by slit-lamp examination. in the rk-treated eyes, 15 (11%) of 140 swabs were positive, compare ...19873619747
immunologic modulation of virus-induced pathology in a murine model of acute herpetic retinal necrosis.unilateral inoculation of herpes simplex virus type 1 (kos strain) into the anterior chamber of balb/c eyes produces an ocular disease with a distinctive differential pattern of retinal pathology. specifically, the retina of the inoculated eye remains histologically intact, whereas the contralateral retina becomes necrotic. we demonstrate that retinal necrosis in opposite uninjected eyes directly correlates with the presence of herpes simplex viral antigens, whereas the intact retinas of virus-i ...19873623838
antiherpesvirus activity of 9-(4-hydroxy-3-hydroxy-methylbut-1-yl)guanine (brl 39123) in cell culture.the activity of 9-(4-hydroxy-3-hydroxymethylbut-1-yl)guanine (brl 39123) against several herpesviruses was compared with that of acyclovir (acv). in plaque reduction tests with clinical isolates of herpes simplex virus type 1 (hsv-1), herpes simplex virus type 2 (hsv-2), and varicella-zoster virus, mean 50% inhibitory concentrations (ic50s) (n = number tested) for brl 39123 were 0.4 (n = 17), 1.5 (n = 13), and 3.1 (n = 5) micrograms/ml, respectively. corresponding ic50s for acv were 0.2, 0.6, an ...19873631945
quantitative studies on langerhans cells in mouse corneal epithelium following infection with herpes simplex virus.dendritic langerhans cells (lcs) were identified in flat-mount preparations of mouse corneal epithelium after staining for atpase activity. they were found predominantly in the limbus, but after inoculating the cornea with hsv1 strain sc16 lc, numbers increased both in the limbus and the central cornea. numbers of lcs reached a maximum on day 8 and if severe keratitis was present remained high at least until day 22. a small but significant increase in lcs was also found in the opposite, uninocul ...19873653284
cytological and immunological study of the aqueous humor in acute retinal necrosis syndrome.we experienced 4 cases of acute retinal necrosis syndrome, and performed anterior chamber paracentesis as a diagnostic aid in their acute and convalescent phases. the aqueous humor obtained by it was used for measuring antibody titers to herpes group virus and electron microscopic observation. one case showed elevated titer to herpes simplex virus type 1 in the convalescent phase, while the other to varicella-zoster virus, suggesting that these 2 viruses could cause this disease. electron micros ...19873658335
dna sequence responsible for the amplification of adjacent genes.a 10.3-kb dna fragment in the 5'-flanking region of the rat prolactin (rprl) gene was isolated from f1bgh(1)2c1, a strain of rat pituitary tumor cells (gh cells) that produces prolactin in response to 5-bromodeoxyuridine (brdu). following transfection and integration into genomic dna of recipient mouse l cells, this dna induced amplification of the adjacent thymidine kinase gene from herpes simplex virus type 1 (hsv1tk). we confirmed the ability of this "amplicon" sequence to induce amplificatio ...19873677995
potentiated adherence of sickle erythrocytes to endothelium infected by virus.systemic viral infection is a known precipitant of vasocclusive crisis in sickle patients, but the mechanism underlying this clinical observation is unknown. in the present studies, human umbilical vein endothelial cells were infected with herpes simplex virus type 1 (hsv) to model systemic viral disease. the already abnormal adherence of sickle erythrocytes to control endothelium is enhanced 1.8 +/- 0.4-fold to hsv-infected endothelium (p less than 0.001). this component of potentiated adherenc ...19873680511
measurement of the stratum corneum drug reservoir to predict the therapeutic efficacy of topical iododeoxyuridine for herpes simplex virus infection.a rapid, in vivo measurement of the penetration of antiviral compounds into the skin would improve our ability to predict the therapeutic efficacy of topical treatments for herpes simplex virus (hsv) infection. we have studied the concentration of iododeoxyuridine (idu) in the stratum corneum of guinea pig skin by tape stripping at different time points after single and multiple topical doses of the drug. these results were correlated with the efficacy of topical idu against an experimental cuta ...19873680984
