Methanolic Extract of Curcuma caesia Roxb. Prevents the Toxicity Caused by Cyclophosphamide to Bone Marrow Cells, Liver and Kidney of Mice

Introduction

With an ever increasing cause of cancer, it has been recommended to treat with conventional drugs, however because of the side effects caused by the conventional drugs, the research on medicinal plants has been intensified due to their less adverse and toxic effects.

Objectives

The primary objective of the present study was to evaluate the protective effect of the medicinal plant Curcuma caesia Roxb. against free radicals ABTS⁺ and O₂^-. Also it was aimed to evaluate the protective effect of C.caesia Roxb. against the chemotherapeutic drug Cyclophosphamide and its side effects in liver and kidney.

Methods

The rhizomes of the plant was extracted with methanol through soxhlet and its antioxidant activity was tested against ABTS+ and O₂^- . For antigenotoxic studies, animals were divided into eight groups and micronucleus assay was employed and for biochemical analysis serum sample was collected from the blood and SGOT, SGPT analysis was performed. Also the biochemical analysis was performed from both the liver and kidney.

Results

The methanolic extract of Curcuma caesia Roxb. was found to scavenge the free radicals ABTS⁺ and O₂^- . the micronuclei formation was found to be increased in the positive control group as compared to the negative control group significantly (P<0.002) however increase in the number of micronuclei was found to be decrease with the pretreatment of the extract at different concentrations significantly as compared to the negative control groups (P<0.01, P<0.005,P<0.001). The increased level of serum SGPT and SGOT as well as peroxidation level in both liver and kidney due to treatment of cyclophosphamide was also found to be decreased with the pretreatment of the extract significantly as compared to the positive control groups. There was decreased in the level of endogenous antioxidant such as GSH and GR in the positive control group however decreased level of GSH and GR was found to be increased with the pretreatment of the methanolic extract of C. caesia Roxb.

Conclusion

The present study suggested that the methanolic extract of C. caesia Roxb has not shown any genotoxicity and reduces the genotoxicity caused by cyclophosphamide. It was also to have the protective effects against the liver and kidney. So it could be provided as one of the herbal supplementation in chemoprevention of CP to ameliorate the side effects of it.
