The normal cell passes through several stages (Accumulation stage, Detoxification stage, Formation of free radical stage and Activation of nuclear factor kappa B stage and the shutting down of programs of cell death stage) to become a cancerous cell. The success of the therapeutic strategy to treat cancer depends on making either one or both programs of cell death run again. Shutting down one stage completely will be sufficient to stop the transformation of the natural cell into a cancerous cell, which eliminates the production of hydrogen peroxide, thus the activity of the NF-Kb will be inhibited. However, shutting down all stages is the most comprehensive therapeutic strategy and guarantees treatment success.展开更多

In the present work, the experimental formula was designed to remove these blockers. It was applied on 120 Swiss albino mice which were inoculated intraperitoneally and subcutaneously with Ehrlich Ascites Carcinoma cells;1 × (106) cell/mouse. The activity of the cell death programs of the tumor was detected by measuring the volume of Ascites fluid, counting the number of dead cancer cells, measuring the size of the tumor, detecting the positive reaction of caspase enzyme in cancer cells and presence of macrophages and apoptotic bodies in tumor tissue. The experimental formula succeeded in removing the blockers of the cell death program in cancer cells returning the cell death program to work again.展开更多
