abstract: herpes simplex encephalitis (hse) is a life threatening outcome of herpes simplex virus (hsv) infection of the central nervous system (cns). hsv accounts for 2-5 percent of all cases of encephalitis. one third of cases occur in those younger than 20 years old and one half in those older than 50 years old. clinical diagnosis is recommended in the encephalopathic, febrile patients with ...

PURPOSE To investigate the effect of Fas and Fas ligand (FasL) deficiency on the development of herpes stromal keratitis and on the von Szily model of herpes retinitis in C57BL/6 mice, which are ordinarily resistant to development of both of these herpetic diseases. METHODS Anterior chamber inoculation of the right eye of each mouse with various titers of HSV-1 (KOS strain) was performed. Bot...

c.ontinuing recurrence of disease is one of the most troublesome characteristics of herpes simplex keratitis. If ocular herpes were a one-time infection, the likelihood of deep involvement, with its scarring, decreased vision, and even blindness, would be much smaller. With each recurrence, the chance of encountering these complications increases. Recent advances in research have led to a bette...

Herpetic keratitis is caused by herpes simplex virus (HSV) and is a common cause of corneal blindness. Following a primary ocular herpetic infection, latency of the virus occurs, followed by subsequent recurrences of herpetic keratitis. Such recurrences may lead to structural damage of the cornea. Recurrent herpetic keratitis is a common indication for corneal transplantation. Recurrences of he...

Ia antigen (class II antigen) is a histocompatibility antigen that foreign peptides associate with, before antigen presentation to T cells and subsequent triggering of the CD4 T cells. Although corneal epithelium is normally Ia negative it may become Ia positive under abnormal circumstances but the functional significance of this is uncertain. In this study the expression of Ia antigen on corne...

Brown alga, Turbinaria conoides was successively extracted with n-hexane, cyclohexane, methanol and ethanol:water (1:1). The extracts were evaluated for antibacterial and antifungal activities by disc diffusion method. Minimal inhibitory concentration was determined for active extracts by broth dilution method. The antiviral activity and cytotoxicity of the extracts were tested in human embryon...

Herpes simplex virus is responsible for numerous ocular diseases, the most common of which is herpetic stromal keratitis. This is a recurrent infection of the cornea that typically begins with a subclinical infection of the cornea that establishes a latent infection of sensory ganglia, most often the trigeminal ganglia. Recurring infections occur when the virus is reactivated from latency and t...

Herpes simplex virus (HSV)-induced ocular disease is occurring in epidemic proportions throughout the world, and is the number one cause of unilateral corneal blindness in all developed countries. We have found, in a mouse model of herpes simplex keratitis (HSK), that products encoded by the Igh-1 locus on chromosome 12 exert a profound influence on the immune/inflammatory response in the corne...

The replication of herpes simplex virus type I and herpes simplex virus type 2 was studied in two isolated hamster cell lines. These lines developed after being treated with herpes simplex virus type 2 inactivated with 7,~2-dimethylbenz(a)anthracene. One cell line that developed, HDC-22, had a hypodiploid chromosome number and was missing a D-group chromosome. Growth studies revealed that this ...
