background and objectives: meningoencephalitis in iranian children is frequent, but encephalitis is rare .the frequency of hhv-6 and hhv-7 in central nervous system diseases of our children is unclear. the aim of this study was searching the dna-s of hhv-6 & hhv-7 in csf samples of children with meningoencephalitis materials and methods: a cross sectional study (2007-2009) was done in ped...
مقدمه و هدف: در سالهای اخیر با افزایش سویههای مقاوم به دارو در انواع ویروسها، یافتن مواد طبیعی با خواص ضد ویروسی که دارای اثرات جانبی کمتری نیز باشند مورد توجه محققین قرار گرفته است. بلوط گیاهی است که دارای اثرات مختلف درمانی از جمله اثر ضد باکتریایی و قارچی میباشد. این مطالعه با هدف تعیین حداقل غلظت کشنده عصاره هیدروالکلی گیاه بلوط روی ویروس هرپس سیمپلکس نوع یک در کشت سلول کلیه نوزاد هامست...
BACKGROUND The epidemiology of human herpesvirus 6 (HHV-6) encephalitis after allogeneic hematopoietic cell transplantation (HCT) and its relationship with HHV-6 reactivation have not been sufficiently characterized. METHODS This prospective, multicenter study of 230 allogeneic HCT recipients investigated the epidemiology of HHV-6 reactivation and HHV-6 encephalitis. Plasma HHV-6 DNA load was...
Background and Aims: Among Human Immunodeficiency Virus (HIV)-infected individuals, Epstein-Barr virus (EBV) and Human Herpesvirus (HHV)-8 could cause significant illness as opportunistic infections. The purpose of the present study was to evaluate the prevalence of EBV and HHV-8 in saliva specimens obtained from HIV-1 infected Iranian individuals under the Highly Active Antiviral Therapy (HAAR...
Human herpesvirus 6 (HHV-6) is a lymphotropic betaherpesvirus that productively infects T cells and monocytes. HHV-6 isolates can be differentiated into two groups, variants A and B (HHV-6A and HHV-6B). Here, we show a functional difference between HHV-6A and -6B in that HHV-6A induced syncytium formation of diverse human cells but HHV-6B did not. The syncytium formation induced by HHV-6A was o...
Human herpesvirus-6A (HHV-6A) and human herpesvirus-6B (HHV-6B) are two closely related viruses that infect T-cells. Both HHV-6A and HHV-6B possess telomere-like repeats at the terminal regions of their genomes that facilitate latency by integration into the host telomeres, rather than by episome formation. In about 1% of the human population, human herpes virus-6 (HHV-6) integration into germl...
Human herpesvirus 6 (HHV-6) DNA levels in peripheral blood mononuclear cells were prospectively evaluated in 20 cytomegalovirus-seronegative allogeneic marrow transplant patients and in 10 healthy control subjects. Blood and saliva specimens obtained weekly for 3 months after transplant were evaluated by quantitative HHV-6 polymerase chain reaction. One of 20 patients experienced primary HHV-6 ...
Human herpesvirus-6 (HHV-6) is a T lymphotropic herpesvirus belonging to the Betaherpesvirinae subfamily. HHV-6 was long classified into variants A and B (HHV-6A and HHV-6B); however, recently, HHV-6A and HHV-6B were reclassified as different species. The process of herpesvirus entry into target cells is complicated, and in the case of HHV-6A and HHV-6B, the detailed mechanism remains to be elu...
It has been reported that reactivation of human herpesvirus-6 (HHV-6) causes a failure of hematopoiesis. To clarify the mechanisms of bone marrow suppression induced by HHV-6 infection, it is necessary to establish an in vitro model of HHV-6 infection in hematopoietic progenitor cells. We have established two novel Philadelphia chromosome-positive myeloid cell lines, SAS413 and SAS527, which po...
مقدمه: با توجه به شیوع بالای آلودگی به ویروس های تبخال و بالا بودن مقاومت دارویی در آنها، یافتن داروهای ضدهرپسی جایگزین برای کاستن از بروز مقاومت، ضروری به نظر می رسد. طب شرقی برای درمان ضایعات تبخالی گیاهان دارویی ارایه می دهد. هدف: مرور مطالعات انجام شده در باره درمان های گیاهی هرپس در طب شرقی و بررسی در دسترس بودن آن گیاهان در ایران. روش: در این مطالعه narrative review گیاهان دارویی مؤثر بر ...
