Methods Anticancer activities were studied against Ehrlich Ascites Carcinoma(EAC) cells in Swiss albino mice by monitoring parameters such as tumor weight measurement,survival time of tumor bearing mice,tumor cell growth inhibition,and so on.Some hematological parameters,such as red blood cells,white blood cells,and hemoglobin content,were also measured. Results The results showed that BSC has a positive effect against EAC cells.An assessment was conducted by comparing these results with those obtained using the standard drug bleomycin. Conclusions The BSC compound can be considered as a potent anticancer agent.展开更多

A partially purified protein with Superoxide Dismutase (SOD)-like activity extracted from leaves of Raphnus sativus was tested for its ability to down regulate liver metastasis of Ehrlich Ascites Carcinoma Cell (EAC) intraperitoneally implanted in albino mice. Sixty albino mice were divided equally into 4 groups. Group I mice (G1 control) were treated with physiologic saline solution for 7 days. Group 2 mice (G2) were injected with the partially purified protein. Group 3 mice (G3) were intraperitoneally inoculated with EAC cells and treated with the partially purified protein. Group 4 mice (G4) were inoculated EAC cells and treated with physiologic saline solution. The results showed a disturbance in liver functions. This disturbance was observed as a reduction in the values of serum albumin, hemoglobin, total counts of erythrocytes and platelets, total lipids in liver tissues, erythrocytes SOD activity, serum glucose, reduced glutathione (GSH) and the trace elements (Fe, Mn, Zn, and Cu) contents in liver and spleen tissues as well as the elevation of serum transaminases activities, the levels of malondialdehyde in blood, DNA and RNA of liver tissues in the infected mice (G4). On the other hand, in G3, after treatment with the partial purified protein all these parameters restored their normal values and became near from the normal group (GI). Moreover, the protein showed no toxicity towards the mice as shown in G2. It could be concluded that a partially purified protein with Superoxide Dismutase (SOD)-like activity extracted from leaves of Raphnus sativus as a nature source has a promised future in controlling liver metastasis.展开更多

The antitumor effect of stearic acid-grafted carboxymethyl chitosan was assessed by the estimation of TGF- β and VEGF in serum in addition to the estimation of tumor volume, median survival time (MST), percentage of increase in life span (ILS%) as well as the contents of total lipid, DNA and RNA in liver tissues. Hematological profiles (hemoglobin, red blood cells, and platelets) were also assessed. In addition, liver function tests and the redox status were estimated. TGF- β, VEGF, DNA, RNA, and malondialdehyde (MDA) levels, in addition to serum alanine transaminase (ALT) and gamma glutamyl transferase (GGT) activities as well as total white blood cells counts and tumor volume were all highly significantly increased (P < 0.001) in untreated EAC-bearing mice compared to controls. However, hematological profiles, total lipid in liver tissues and serum albumin were highly decreased in EAC-bearing mice compared to controls. All these parameters were restored to the normal levels in SA-CMC treated EAC-bearing mice com- pared to the untreated EAC-bearing mice. It is thus concluded that stearic acid-grafted carboxymethyl chitosan has a remarkable antitumor activity against EAC in Swiss albino mice through downregulation of TGF-β and VEGF.展开更多
