Group 2 and 3 animals by using vernier callipers on alternative days for the entire life span of the animals. Tumor volume was calculated using the formula V = 0.5ab2, where `a’ and `b’ indicates the major and minor diameter, respectively [25,26]. At the end of 30th and 45thPreparation of Breast Adenocarcinoma CellsEhrlich ascites carcinoma (EAC) is an undifferentiated carcinoma, originally hyperdiploid and has high transplantable capability, rapid proliferation, shorter life span and 100 malignancy. EAC resembles human tumors which are most sensitive to chemotherapy due to the fact that they are undifferentiated and have a rapid growth rate.

Histopathalogical sections of thigh and liver of a tumor bearing mouse with and without treatment with MESB after 30th day A(a ) and C(a ) and 45th day B(a ) and D(a ) of development of tumor. Magnification shown are 10x (a, c and e in all panels) and 40x (b, d and f in all panels). doi:10.1371/journal.pone.0047021.gday of experimental period, one animal from each group [normal (group 1), tumor (group 2) and MESB treated tumor animals (group 3)] was sacrificed by cervical dislocation, tissues were collected and stored under appropriate conditions. Each experiment was repeated three independent times. The percentage of increase in lifespan was calculated 25837696 and compared with JSI-124 control animals. The death pattern for control animals and MESB treated animals was recorded and increase in lifespan was calculated using the formula [(T-C)/C] x100, where `T’ indicates the number of days the MESB treated animals survived and `C’ indicates the number of days tumor animals survived [25,27].Histological EvaluationTumor and liver tissues of normal and experimental mice were collected and processed as per standard protocol. Briefly, the tissues were embedded in paraffin wax, sectioned at 5?0 mm in rotary microtome (Leica Biosystems, Germany) and stained with hematoxylin and eosin [25,28]. Each section was evaluated by light microscopy and images were captured (Carl Zeiss, Germany).Evaluation of Side Effects in Normal AnimalsSwiss albino mice were fed with MESB (2 g/ml) for ten days to assess the side effects. Control and treated groups consisted of 8 mice each. Body weight was measured on every alternate day and the average body weight was plotted. To evaluate the effect of MESB on physiological functions, blood was collected after ten days of MESB treatment and analysed as described earlier [25]. Serum was separated from the blood and used for liver and kidney function tests by comparing the levels of alkaline phosphatase (ALP), creatinine and urea. The blood count was performed by scoring the number of RBC and WBC in whole blood as described earlier [25]. Values obtained were presented as mean6SEM.The Chemopreventive Effect of MESBFor each experiment, out of 10 animals, 5 (group 1) were orally fed with MESB (2 g/kg b.wt) for 20 days prior to the EAC injection and treatment was continued up to 45 days. Group 2 animals were considered as tumor control with no MESB treatment. The tumor volumes were measured after 12 days of EAC injection in both group 1 and group 2 animals. Each experiment was repeated two independent times. The percentage of increase in lifespan was calculated and compared with control animals.Immunohistochemical (IHC).Group 2 and 3 animals by using vernier callipers on alternative days for the entire life span of the animals.
