The aerial parts of Stachys laxa Boiss. and Buhse.from Siah-bishe in Mazandaran province, Stachys trinervis Aitch. and Hemsl. from Karaj in Alborz province, Stachys subaphylla Rech. F. and Stachys turcomanica Trautv. from Golestan province have been collected in May 2008. Total extracts were obtained through MeOH/H2O (80/20) and then partitioned between CHCl3, EtOAc and MeOH. These fractions...

Background and objectives: ZatariamultifloraBioss. (ZM) has shown several effects in gastrointestinal, respiratory and nervous system. In this study, the effect of Z. multiflora was examined in colon cancer cell lines of Caco-2. Methods: Total extract and petroleum ether, chloroform and methanol fractions of the plant were prepared us...

There are considerable efforts to identify naturally occurring substances as new drugs in cancer therapy. Many components of medicinal plants have been identified that possess substantial anticancerous properties. This prompted us to investigate the effect of Scrophularia striata (an Iranian species belonging to the Scrophulariace family) extract on the growth of astrocyte cancer cell line (132...

the objective of the study was to evaluate thecytotoxic effects of aqueous fruit extract of cucumis melo in human prostate cancer cell line (pc-3) using mttand neutral red assays. the crude aqueous extract of c.melo was prepared by cold maceration method, filtered,concentrated and tested on pc-3 cell line. dose-dependent cytotoxic activitieswere exhibited by human prostate carcinoma pc-3 cell l...

Cell culture technique has been used for detection and confirmation of many different viruses in clinical samples. Although, new diagnostic methods have been developed for viral infections, traditional cell culturetechnique is still regarded as the “gold standard” for several infectious agents such as human cytomegalovirus(HCMV). In the present study, a new human fetal foreskin fibr...

One of the major complications in cancer chemotherapy is the development of resistance, and cisplatin, as one of the important medicines in treatment regimens of different cancers is not excluded. One of the most described cellular defense mechanisms involved in resistance is glutathione (GSH) and in this study, the effects of cisplatin on the total intracellular GSH level (GSHi) in some sensit...
