Abstract
Aim
Therapeutic choices for cancer patients include many combinations of therapeutic protocols. The present study aimed to investigate and discuss the combined effects of magnetic field and chemotherapy treatment on Ehrlich tumor-induced growth in Swiss albino mice. The benefits of both treatments are discussed and interpreted.
Methods
Fifty adult male mice were randomly divided into two groups; ten mice in the first group served as control group and forty in the second group which received a single dose IP injection of tumor fluid (0.02 Ml) to induce tumor. Ten days post injection to allow the tumor to growth, the 40 mice were sub- divided in to 4 sub-groups 10 mice pre each to introduce the treatment.
Results
The results indicated tumor growth inhibition regarding mean tumor volume variation (ml) presented. All treatments display tumor growth prevention effect compared to control untreated mice. Treatment with Dox + 7G (MF) exposure exhibited a significant inhibition of tumor growth than that treated alone with DOX or magnetic field; 82% inhibition for DOX + MF 7 G against 60% for 7 G , and 31% for DOX only. Optical density data show a higher values of the molar absorption coefficient ε for all treated groups than untreated one. The fluorescence emission spectra of Hb show an emission peaks λem at 465, 515, and 639 nm. Hematological examination might indicate to discriminative effects to RBCs, WBCs or/and Hb for all treated groups. Moreover, treatment with Dox + 7G MF shows a proper discriminative effects than that treatment with DOX or magnetic field only. Osmotic fragility (OF) test indicates that the combination between drug and magnetic field have nontoxic effect against RBCs membrane.
Conclusion
Our findings support further exploration of the potential of magnetic fields in cancer therapeutics, either as adjunct or primary therapy. It may be due to enhancing the drug interaction with tumor cells which increase the therapeutic index of DOX and resulted in increased anti-tumor activity against Ehrlich tumor models. These benefits promote the use of the magnetic field in cancer with chemotherapy over the other traditional treatment agents this highly adapted manner can be used in improving the clinical treatment protocol and fights against cancer.
