[ 1 ] - Toxicopathological examinations after repeated intraperitoneal administration of silver nanoparticles in the Wistar rat model
Objective(s): Due to wide range of medical applications as bactericidal agents, nanosilver particles (NSPs) are manufactured worldwide in large quantities. However, potential toxicity impacts of NSPs in humans and animals still remain poorly understood. The objective of this study was to investigate clinical observations, mortality and pathological changes in rats follow...
[ 2 ] - Evaluation of Cardiopulmonary Toxicity Following Oral Administration of Multi-walled Carbon Nanotubes in Wistar Rats
Objective(s): Carbon nanotubes have unique mechanical, electrical, and thermal properties, with potential different applications in nanomedicine, electronics, and other industries. These new applications of carbon nanotubes in different industries lead to the increased exposure risk of nanomaterials to human. Up to now, all aspects of carbon nanotubes toxicity are not com...
[ 3 ] - Inhibition of Nephrotoxic Activity of Mesobuthus Eupeus Scorpion Venom by Commercial Polyvalent Antivenom in Rabbits
Background: Immunotherapy is the only specific treatment for scorpion envenomation. In the present study, the protective effects of polyvalent antivenom against histopathological complications in kidneys and marker changes (BUN and creatinine) induced by Mesobuthus eupeus (Me) scorpion venom was investigated in anesthetized rabbits. Methods: Twenty four rabbits were randomized into four gro...
[ 4 ] - Transcriptional effects of Organochlorine o,p′-DDT and its Metabolite p,p′-DDE in Transfected MDA-MB 231 and MCF-7 Breast Cancer Cell Lines
Background: The organochlorine DDT has estrogenic activity but the mechanism underlying the estrogenic activity of this pesticide remains unclear. In the present investigation here, we studied the transcriptional effects of a synthetic organochlorine pesticide o,p’-DDT [1.1.1.-trichloro-2-(o-chlorophenyl)-2-p-chloriphenyl ethane] and its metabolite p,p'-DDE (2-2-bis(4/chlorophenyl)-1-1-di...
[ 5 ] - خالص سازی توکسین اپسیلون از سویه واکسینال کلستریدیوم پرفرنژنس تیپ D با استفاده از کروماتوگرافی تبادل یون و ژل فیلتراسیون
باکتری کلستریدیوم پرفرنژنس تیپ D در بره‌ها، گوساله‌ها، کره اسب‌ها، بچه خوک‌ها و جوجه‌ها باعث ایجاد بیماری انتروتوکسمی یا pulpy kidney می‌شود. هم‌چنین در انسان، عامل بیماری enteritis necroticans می‌باشد. مهم‌ترین توکسین تیپ D توکسین اپسیلون است. این توکسین به عنوان مهم‌ترین فاکتور ویرولانس باکتری کلستریدیوم پر فرنژنس تیپ D در بیماری‌زایی به شمار می‌رود. در مطالعه‌ی حاضر، عملیات خالص‌سازی...
[ 6 ] - Acute toxicity investigation regarding clinical and pathological aspects following repeated oral administration of iron oxide nanoparticles in rats
Iron oxide nanoparticles (IONPS) have potential different applications in nanomedicine. These new applications of IONPS have raised exposure risk of this nanomaterials to humans. Up to now, all aspects of IONPS toxicity are not fully clear following animal’s exposure with these novel compounds. This study aimed to investigate the acute toxicity effects of IONPS in laboratory animals regarding p...
