مقدمه آسم و رینیت آلرژیک به همراه کهیر از جمله بیماریهای مهم و شایع درهر جامعه ای هستند. هدف از این مطالعه تشخیص آلرژنهای هوایی از راه تست پوستی پریک در بیماران فوق در استان مازندران، ساری می باشد. روش کار در این مطالعه توصیفی-مقطغی تست پوستی پریک برای آلرژنهای هوایی در بیماران آسمی، رینیت آلرژیک یا هر دو و کهیر که ازنظر بالینی و تستهای پاراکلینیک اثبات شده اند و شرایط انجام تست پوستی پریک را د...
[ 4 ] - Protective role of HLA-DRB1*11 against juvenile idiopathic arthritis living in North Eastern Iran
Objective(s): Juvenile idiopathic arthritis (JIA) is one of the most common chronic rheumatic diseases in children. The complex nature of this immune-mediated disease owes itself to several predisposing genes and environmental factors affecting its pathogenesis. Conducted in Iran, this study was originally intended to investigate every possible association between HLA DRB1 alleles and a suscept...
[ 5 ] - The Effect of Safranal on Th1/Th2 Cytokine Balance
Background: Several biological and medical benefits of Saffron, Crocus sativus (Iridaceae), have been demonstrated. However, mechanisms of actions for purified constituents are greatly unknown. Objective: To examine the effects of Safranal, a main constituent of Saffron stigma, on cell viability and cytokine profile of peripheral blood mononuclear cells (PBMC) were examined. Methods: Effect...
[ 6 ] - Serum levels of vascular endothelial growth factor in chronic Obstructive pulmonary disease
Background :Chronic obstructive pulmonary disease (COPD) is a third leading cause of death. Methods : In this case control study, we prepared 5 cc bloods from the antecubital vein of 100 COPD patients and 40 healthy individuals as control group. Vascular endothelial growth factor (VEGF) expression protein level was measured by ELISA in both groups. Results : We found that concentration of...
[ 7 ] - Skin inflammatory reactions to capsaicin in rheumatoid arthritis patients compared to healthy controls
Objective: Previous studies have examined the role of sensory nerves and neural mediators in symmetrical joint inflammation and autoimmunity in rheumatoid arthritis (RA). In this study, we sought to examine the association between capsaicin skin test and disease activity in RA patients. Materials and Methods: Eighty RA patients (case group) and 20 healthy volunteers were enrolled in this experi...
[ 8 ] - High proviral load of human T cell lymphotropic virus type-1 facilitates coronary artery diseases
Objective(s): Coronary artery disease (CAD) is known as a life threatening disease, worldwide. In this study the role of HTLV-1 infection was evaluated on cardiac involvement in an endemic region of northeastern Iran.Materials and Methods: Serologic and molecular tests for HTLV-1 infection were carried out in subjects who had coronary an...
[ 9 ] - Synergy between parthenolide and arsenic trioxide in adult T-cell leukemia/lymphoma cells in vitro
Objective(s): Adult T-cell leukemia/lymphoma (ATLL) is an aggressive lymphoid malignancy with low survival rate and distinct geographical distribution. In search for novel chemotherapeutics against ATLL, we investigated the combinatorial effects of parthenolide, a sesquiterpene lactone with valuable pharmaceutical activities, and arsenic trioxide (ATO) in vitro</em...
[ 10 ] - Interaction of perforin and granzyme B and HTLV-1 viral factors is associated with ATL development
Objective(s): Human T cell leukaemia virus type 1 (HTLV-1) is associated with adult T cell leukaemia (ATL), a malignant lymphoproliferative disease that infects CD4 T cells. It is not clear why the majority of HTLV-1-infected individuals remain asymptomatic carries (ACs) and a minority develop ATL. Cellular immune response has a critical role in ATL and destroys malign...
[ 11 ] - Awareness of laboratory students of Mashhad University of Medical Sciences about human T-cell lymphotropic virus type 1 (HTLV-1)
Introduction: HTLV-1 virus is a human retrovirus and it causes several chronic diseases. So far, there is not any vaccine or satisfactory treatment that has been developed for infections caused by this virus. Moreover, the best way to control the infection is prevention and the best way to prevent it is education. Therefore, our study was conducted to investigate the knowledge and attitudes of ...
