چکیده
Objective(s): With no substantial cost, we injected L-arginine into the rat’s corpus callosum (CC) to create animal model of multiple sclerosis (MS) and investigated the pre-injection effect of gold nanoparticles (GNPs). Materials and Methods: Adult male Wistar rat (250-300 g) was surgically cannulated at the CC, and after recovery it was injected L-arginine (3-200 µg/rat, intra-CC) once daily for 3 to 5 consecutive days. GNPs (0.001-0.01 µg/rat, intra-CC) were injected alone or prior to the L-arginine using the same procedure. Control group solely received saline (1 µL/rat, intra-CC). Brain was studied with luxol fast blue. Weight change was also analyzed via the analysis of variance (ANOVA). Results: L-arginine significantly induced (p< 0.05) a reduction in the fiber density while the neurons increased (p< 0.05). Single GNPs reduced (p< 0.05) the fiber and neuron densities; however, pre-injection of NPs caused myelinated fibers and uniform density of neurons. Conclusion: The L-arginine may trigger demyelination by pro-inflammatory nitric oxide (NO), and the GNPs may improve this effect.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
