Introduction: Plants have a range of phenolic compounds that have antioxidant properties and these natural antioxidants reduce the risk of cancer by protecting cells and increasing the strength of antioxidants in the plasma. The aim of this study was evaluated cytotoxicity effects of methanol extract of Johreniopsis stricticaulis on MCF-7 cell line. Methods: After collection of Johreniopsis str...
it has been reported that several members of convolvulaceae family such as convolvulus arvensis possess cytotoxic activity on some tumor cell lines. proteoglycan mixture, the water extract of c. arvensis with high molecular weight, has potent anti-angiogenesis and stimulating effects. in this study, arial parts of c. arvensis were collected and identified, and the cytotoxic effects of chlorofor...
DNA-based cytotoxic agents: Nanopores composed of folded DNA featuring a hydrophobic belt of ethyl phosphorothioate groups insert into bilayer membranes and kill cancer cells. The mode by which the pores achieve cell killing is elucidated with confocal microscopy.
Background and Objective: Proliferation and apoptosis of lymphocytes are essential parts of the immune system. Most anti-cancer chemotherapy drugs such as vincristine target cell cycle and induce apoptosis in cancer cells. In other words, dividing cells undergo more apoptosis, which may also include the normal proliferating lymphocytes responsive to malignancies as well. Materials ...
Cationic proteins purified from human polymorphonuclear leukocyte granules exert a cytotoxic effect on mammalian tumor cells. This effect is time and concentration dependent, is inhibited by the anionic agent heparin, and is enhanced by preheating the cationic proteins. Other strongly basic proteins (histone, protamine) also exhibited cytotoxic activity. Myeloperoxidase isolated from human leuk...
The present study was carried out to evaluate the cytotoxic effects of aqueous (AE) and ethanolic (EE) extracts of Artemisia herba alba on human laryngeal carcinoma (Hep-2) cell line and murine mammary adenocarcinoma (AMN-3) cell line in vitro. The in vitro cell growth assay showed that there were timeand concentration-dependant cytotoxic effects of both extracts on the tested cell lines. The r...
STATEMENT OF PROBLEMS An ideal antimicrobial agent should have minimal cytotoxic effect to host cells. PURPOSE The aim of this study was to determine the cytotoxic effect of three commercial mouthwashes (Chlorhexidine, Persica and Irsha) on the cultured fibroblasts. MATERIAL AND METHODS For determining the cytotoxic effect of Irsha, Chlorhexidine and Persica, uninfected cells were grown in ...
BACKGROUND Cytotoxicity of root canal irrigants is important due to their close contact with host tissues. The aim of this study was to assess the cytotoxic effect of NaOCl 3%, Chx 2%, and MTAD on rat periodontal ligament fibroblasts, at 0.1 and 100 µl/mL, using WST-1 colorimetric method. MATERIAL AND METHODS Rat ligamental fibroblasts were exposed to the irrigants and their viability was ass...
