هدف ازاین مطالعه بررسی اثر غلظت های مختلف بتا هیدروکسی بوتیرات (4/8mmol/ml ,2/4mmol/ml , 1/2 )و بتا استرادیول (10ng/ml ,1ng/ml)بر متوسط مقدار فاگوسیتوز و انفجار تنفسی (آزمایش احیا نیترو بلوتترازولیوم یا NBT) نوترو فیل های جدا شده گاو به صورت in vitro بود. بدین منظور نوتروفیل های نمونه خون گاو جدا شده و سپس باهر یک از تیمارهای فوق به مدت 2 ساعت در دمای 37 C انکویه گردید.هر دو آزمایش فاگوسیتوز و...
A cross sectional pilot study using convenient sampling method was conducted to evaluate various immunological parameters in preterm babies and term babies. Cord blood from 36 preterm and 36 term babies was taken and the following parameters were determined: Immunoglobulin G, A and M, Complement 3 and 4 and NBT. The results showed that NBT was significantly reduced in preterm babies compared to...
The objective of this study was to evaluate the effects of tetramethylpyrazine (TMP) in combination with arsenic trioxide (As2O3) on the proliferation and differentiation of HL-60 cells. The HL-60 cells were treated with 300 µg/mL TMP, 0.5 µM As2O3, and 300 µg/mL TMP combined with 0.5 µM As2O3, respectively. The proliferative inhibition rates were determined with MTT. Differentiation was detect...
Need based transfers (NBTs) are actions to compensate losses after disasters. They are based on shared values and reflect the understanding of the random nature of disasters. To study them, agent based simulations are performed whereby individuals that fall below a threshold (e.g. welfare threshold) will receive help from a single individual who is rich enough to help within a network of connec...
Phagocytes from X-linked chronic granulomatous disease (X-CGD) patients are deficient in their ability to generate superoxide because of a defective gene that encodes a heavy chain of cytochrome b, a critical component in the superoxide-generating pathway. Previously we have shown that a single in vivo treatment of selected X-CGD patients with interferon-gamma (INF-gamma) resulted 14 days later...
A series of new mixed ligand complexes of cobalt(II), nickel(II), copper(II) and cadmium(II) have been synthesized with 3-benzyl-1H-4-[(2methoxybenzylidine) amino]-1, 2, 4-triazole-5thione (MBT), 3-bezyl-1H-4-[(4-chlorobenzylidine) amino]-1, 2, 4-triazole-5-thione (CBT), 3-benzyl1H-4-[(4-nitrobenzylidine)amino]-1, 2, 4-triazole5-thione (NBT) and dehydroacetic acid sodium salt (Nadha). The mixed...
به منظور تعیین اثر برخی آنتیبیوتیکهای رایج در درمان عفونتهای میکروبی گوسفند بر فعالیت نوتروفیلها، آزمایش حاضر به صورت in vitro طراحی و اجرا شد. در این مطالعه نوتروفیل خالص گوسفند از نمونه خون محیطی جداسازی و با آنتیبیوتیکهای اکسیتتراسایکلین و انروفلوکساسین (غلظتهای صفر، 1 ، 10 ، 100 و 200 میکروگرم در میلیلیتر) و پنیسیلین G (صفر، 250، 500، 1000، 2000 و 4000 واحد در میلیلیتر) به مد...
Abstract Background: The annual Hajj pilgrimage to Holy Mecca, brings over two million people together in a small confined area through the world. Respiratory illnesses are the most common afflictions during this ceremony presenting as various clinical syndromes. Several microbiologic, Sero-epidemiologic and Immunologic studies have revealed that most of these syndromes are caused by viral i...
Beak trimming is necessary in commercial broiler breeders to prevent or decrease trauma as they mature. Two common beak-trimming methods were evaluated by early performance comparison with nontrimmed chicks (NBT). The robotic electrocautery device (ECD) trims and cauterizes the beak tip. The robotic infrared beak-trimming device (IBT) applies an infrared light beam to destroy the live basal tis...
