Carboxy methyl dextran benzylamide jorge (CMDBJ) is a derivatized dextran prepared from native dextran after random carboxymethylation of hydroxyl groups on D-glucose units (CM) and consecutive conversion of some carboxylate groups to benzylamide structures (B). This polymer exhibits an inhibitory action upon the proliferation of 1205 L-U human melanoma(More)
Astaxanthin, a powerful antioxidant, is a good candidate for the prevention of intracellular oxidative stress. The aim of the study was to compare the antioxidant activity of astaxanthin present in two natural extracts from Haematococcus pluvialis, a microalgae strain, with that of synthetic astaxanthin.

Gene therapy with Herpes Simplex Virus thymidine kinase gene (HSV-tk) is effective in various tumor models in vitro and in vivo. We compared the efficacy of the HSV-tk gene therapy in vitro and in vivo in MCF-7 and MCF7-ras cells which form tumor in athymic mice. After viral infection, cells were treated with GCV (Ganciclovir) and live cells were counted.(More)
