BACKGROUND Classical Hodgkin's lymphoma is characterized by Hodgkin and Reed Sternberg cells, which are of B-cell origin in many cases. We recently highlighted the adverse prognostic significance of cytotoxic molecule expression in patients with classical Hodgkin's lymphoma. However, the clinical characteristics of cytotoxic molecule-positive classical Hodgkin's lymphoma remain controversial. ...

objective(s): regarding the presence of many active biological constituents in avicennia marina, the present investigation was carried out to study cytotoxic activity of crude methanol leave extract and column chromatographic fractions of a. marina against mda-mb 231 cell line (human breast cancer cell) and hek (human embryonic kidney cell) line .   materials and methods: the anticancer activit...

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...

Killer lymphocytes provide powerful immune protection from cancer and infection by eliminating dangerous cells. Innate killer cells (principally natural killer cells) and innate-like T cells provide the first response. Antigen-specific immunity by cytotoxic T lymphocytes takes over about a week later and provides life-long immunity. When killer cells recognize a target cell, they mobilize cytot...

EVALUATION OF ANTIFUNGAL, ANTIBACTERIAL AND CYTOTOXIC EFFECTS SOME NEW DERIVATIVES SPIROOXYINDOLES

previous studies have indicated that some species of cuscuta possess anticancer activity on various cell lines. due to the lack of detailed researches on the cytotoxic effects of cuscuta chinensis and cuscuta epithymum , the aim of the present study was to evaluate cytotoxic effects of chloroform and hydroalcoholic extracts of these plants on the human breast carcinoma cell line (mda-mb-468), h...
