نقش سلولهای خونی به عنوان اجزای اصلی دفاع فیزیولوژیک حشرات مهم گزارش شده است. اولین فاکتورهای سیستم گردش خون هستند که در مقابله با انواع تنشها و عوامل بیگانه مشارکت می کنند. تحقیق حاضر، چهار نوع هموسیت همولنف لارو سن چهارم خرطوم بلند دمبرگ چغندرقند شناسایی شد شامل پروهموسیتها، گرانولوسیتها، پلاسموتوسیتها انوسیتوئیدها هستند. بزرگترین از نظر اندازه بودند مجموع فراوانی گرانولوسیتها لاروهای سنین سو...

immunoglobulin e is one of the five classes of immonoglobulins that plays an important role in allergic diseases. production of monoclonal antibodies by a single clonotype against different epitopes of immunoglobulin e has high priority in development of diagnostic kits. in this study, an attempt was made to produce monoclonal antibodies against human immunoglobulin e. balb/c mice were immunize...

abstract introduction: thalassemia is the most common hereditary anemia in iran. the aim of this study was to evaluate the humoral immune system and assess the effect of splenectomy on the serum level of immunoglobulins igg, igm, and iga and complement components in patients with major thalassemia. materials and methods: this interventional semi-experimental study (before-after) was performed o...

diabetes mellitus is a group of metabolic diseases caused by a combination of insulin resistance and impaired insulin secretion by pancreatic β cell. in 2007, 246 million people (roughly 6%) were affected by diabetes worldwide and it is estimated that this will increase to 380 million in 2025. diabetes is associated with several long-term complications such as cardiovascular disease, nephropath...

as igm and iga-enriched preparations are needed to complete the immunotherapeutic spectrum, a simple procedure is described for the preparation of igm and iga enriched immunoglobulins. fraction iii which was prepared by cold ethanol fractionation was treated by octanoic acid followed by ethanol precipitation and ion-exchange chromatography using sephadex deae a-50 and 0.1 m tris-d.35m naci buff...

few biomarkers that can predict the clinical response to allergen immunotherapy (ait) have been identified. the aim of the present study was to investigate parameters that could be used “in predicting the clinical response to ait” in children with asthma caused by house dust mites. we evaluated 107 children with mild persistent asthma who were sensitised only to mite aeroallergens. the study gr...

the clinical behavior of asthma varies with age at onset. this study was undertaken to identify associated markers of adult-onset allergic asthma (age ≥20 years).this cross-sectional study compared two groups: 58 patients with asthma onset at <20 years and 66 with onset at ≥20 years. they were compared depending on results of clinical history, and body mass index (bmi), aeroallergen sensitizati...

hepatitis a virus (hav) infection is a self-limiting disease caused by a 27-nm rna virus from the picorna virus family. its' transmission is primarily via the fecal-oral route. the disease is usually mild and anicteric in children, however the rate of the icteric form, severity, and mortality increase in adult life. the estimated case-fatality rate in age over 40 years is approximately 2%, whil...

introduction: most b-cell malignancies are diagnosed based on morphologic and immunohistochemical criteria. some cases, however, still present a challenge for the pathologist to discriminate between reactive hyperplasia and neoplastic disorders. molecular techniques can be used as a helpful diagnostic tool in these cases. in this study, we assessed the value of polymerase chain reaction (pcr) t...

background: there are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. there are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...
