background and objectives: febrile convulsion is a common disorder in children. viral infections such as human herpes virus 6 (hhv-6) which results in roseola infantum may contribute to developing seizure. the objective of this study was to determine the prevalence of hhv-6 by detecting dna in cerebrospinal fluid (csf) of children with febrile convulsion and without any rash of roseola infantum...

introduction: during the past few years, an increasing body of evidence has suggested a possible role for human herpes virus 6 (hhv-6) in multiple sclerosis (ms) pathogenesis. despite the many reports supporting the relationship between hhv-6 and ms, this association has not been definitely proved or refuted, and the matter remains unresolved. the current study was aimed to investigate any rela...

background and objectives: human herpes 6 virus (hhv-6) could remain latent and chronic in the host cells after primary infection. hhv-6 genome encodes certain trans activation proteins which may results in development of malignantlymphoma. the association of human herpes six virus (hhv-6) infection and hodgkin and non-hodgkin lymphomas is strongly supported by epidemiological studies. the aim ...

Background and objective: Langerhans cell histiocytosis (LCH) is a rare histiocytic proliferative disorder of unknown etiology and mainly affects young children. The histological feature is granuloma-like proliferation of langerhans-type dendritic cells. Although the possible role of viruses such as Epstein-Barr virus (EBV, Human Herpes virus -4</...

background patients with beta thalassemia suffer from increased susceptibility to infections and putridity plays a major role in the patient's morbidity and mortality. the risk of transfusion-transmitted viral infection is well known in these patients. however, there is dearth of information about the seroprevalence of herpes simplex virus (hsv) infection in patients with beta thalassemia in li...

background and objectives:  the molecular genetic of the human herpes virus 8 (hhv8) has now been characterized the pathogenesis of kaposi sarcoma (ks). this study attempted to determine the rate of hhu-8 infection in ks in an iraniann cross sectional study. method &amp; material: in this cross-sectional study, we used paraffin-embedded specimens of 54 clinically well-characterized kaposi sarco...

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...
