objective: envenomation by heamotoxic snakes constituted a critical health occurrence in the world. bleeding is the most sever consequence following snake bite with viperid and crothalid snakes. it is believed that the degradation of vascular membrane caused hemorrhage; in contrast, some suggested that direct cytotoxicity has role in endothelial cell disturbances. this study was to evaluate the...
dacarbazine is an antitumor prodrug which is used for the treatment of malignant metastatic melanoma and hodgkin’s disease. it requires initial activation in liver through an n-demethylationreaction. the active metabolite prevents the progress of disease via alkylation of guanine bases in dna strands. in order to investigate the importance of imidazole ring and its dynamictautomerization in ant...
the imbalance between pro-oxidants and anti-oxidants leads to generation of oxygen/nitrogen free radicals which are implicated in several neurodegenerative diseases. fagonia arabica is an ethno-pharmacologically important ayurvedic herb known to have many medicinal properties like anti-inflammatory, analgesic and antipyretic effects. however, its antioxidant potential has not been investigated ...
the present study was designed to assess the cytotoxicity, anti-inflammatory and analgesic properties of methanol extract of woodfordia fruticosa flowers. cytotoxic activity of methanol extract of woodfordia fruticosa flowers was tested using artemia salina (brine shrimp) bioassay. two doses (400 and 600 mg/kg) were evaluated for the anti-inflammatory activity against the carrageenan, histamine...
overdose of acetaminophen causes severe hepatic necrosis in humans and experimental animals. studies on its hepatotoxicity remain a very active area since some of current data are still uncertain. in this study, freshly isolated rat hepatocytes were used to determine the effects of garlic extract and its component, allicin on the acetaminophen-induced cell cytotoxicity and to compare with the e...
extracts derived from viscum album have been shown to kill cancer cells in vitro. some studies have noted that different species of this plant collected from around the world displayed cytotoxic effects in different extents. in the present study, we evaluated the effects of iranian mistletoe extracts on five cancer cell lines. plants growing on hornbeam tree (carpinus betulus) were collected, a...
osseointegration has been the concern of implantology for many years. researchers have used various ceramic coatings for this purpose; however, piezoelectric ceramics (e.g., barium titanate [bto]) are a novel fi eld of interest. in this regard, bto (batio3 , bto) coating was fabricated by electrophoretic deposition on ti6al4v medical alloy, using sol-gel-synthesized nanometer bto powder. struct...
Multiple sclerosis is a common leading cause of disability worldwide. CD20-expressing B cells play major role in multiple pathogenesis. Hence, anti-CD20 monoclonal antibodies effectively deplete mainly by complement-dependent cytotoxicity, antibody-dependent cell-mediated phagocytosis, and cellular cytotoxicity. While the precise etiology remains unknown, it now recognized that environment...
