The cytotoxic activity of ethanolic extracts of Thymus vulgaris, Thuja orientalis and Achillea millefolium was investigated on various growing tumor cell lines. MTT colorimetric assay was used for measuring the inhibition of cell proliferation. All of the three extracts showed a relatively dose-dependent inhibition of proliferation of human breast cancer (SK-Br-3, MDA-MB-435) and leukemia ...
BACKGROUND Human rhinoviruses (HRVs) are one of the main causes of virus-induced asthma exacerbations. Infiltration of B lymphocytes into the subepithelial tissue of the lungs has been demonstrated during rhinovirus infection in allergic individuals. However, the mechanisms through which HRVs modulate the immune responses of monocytes and lymphocytes are not yet well described. OBJECTIVE To s...
An electron-microscopic examination was made of the process of cell fusion induced by Sendai virus inactivated by ultraviolet light. Ehrlich ascites cells, HeLa cells, rabbit macrophages, rat lymphocytes and nucleated hen erythrocytes were chosen for study because it had previously been shown that these cells could be fused together, with varying degrees of facility, to form artificial heteroka...
objective: cancer is a major health problem worldwide and current therapies for cancer are often limited by short-term efficacy due to drug resistance. there has been much interest in the use of naturally occurring compounds with chemo-preventive and chemotherapeutic properties in the treatment of cancers. rose is one of the most important groups of ornamental plants which their fruits and flow...
background: functional defects in mitochondria are involved in the induction of cell death in cancer cells. the process of programmed cell death may occur through the mechanisms of apoptosis. several potential lead molecules such as camptothecin (cpt) and its analogues have been isolated from plants with anticancer effect. the aim of the present study was to understand the necrotic effect versu...
Salvia chorassanica Bunge is one of the Iranian endemic species of Salvia. There is not any reported literature on S. chorassanica. This study was designed to examine the in-vitro anti-proliferative and proapoptotic effects of the methanol extract of S. chorassanica and its fractions on HeLa cell line. Cells were cultured in EX-CELL®, an animal free medium specially designed for HeLa cell line ...
Introduction: Cancer is the leading cause of death in most countries. There are several methods used to treat cancer. Doxorubicin is one of the most important chemotherapy drugs that has several side effects, such as infertility, hyperuricemia, neuropathy, and cardiomyopathy. This study aimed to evaluate the anti-cancer effects of Naja naja oxiana in comparison with doxorubicin in Hela (Human c...
Objective: Perovskia abrotanoides Karel, belongs to the family Lamiaceae and grows wild alongside the mountainous roads inarid and cold climate of Northern Iran. The anti-tumor activity of P. abrotanoides root extract has been shown previously. This study was designed to examine in vitro anti-proliferative and pro-apoptotic effects of flower extract of P. abrotanoides on MCF-7 and Hela cell lin...
Background and Aim: Helicobacter pylori is the etiologic agent of chronic –active gastritis, gastroduodenal ulcers in humans, and a co-factor in the occurrence of gastric cancer and mucosa-associated lymphoid tumors, Adhesion of H.pylori to the gastric mucosa is a critical and also initial step in the pathogenesis of the disease. Bacterial adhesion inhibitory agents provide a novel pharmacologi...
