Determination of Antineoplastic Activity of Rohituka, Aphanamixis Polystachya (Wall) RN Parker in Hela Cells: Correlation with Clonogenicity and DNA Damage
ثبت نشده
چکیده
Though many of the presently used anticancer drugs are originated or derived from plants, an attempt to the isolation and clinical usage of single compound has caused severe adverse side effects like, myelosuppression, alopecia, nausea, gastrointestinal, reproductive and nephrotoxicity. In addition, most of the modern chemotherapeutic agents have been reported to induce secondary malignancies due to their carcinogenic potential in patients receiving therapy [1]. This necessitates a continued search for newer novel natural products and/or their semisynthetic analogs that may be useful as potential cancer chemotherapeutic drugs in the hope that it will be possible to encounter an agent/s that will be highly effective in treating neoplastic disorders without any side effect or minimum side effects when compared to the synthetic drug/s [2].

Preclinical Determination of the Anticancer Activity of Rohituka (Aphanamixis polystachya) in Ehrlich Ascites Tumor-Bearing Mice
Anticancer activity of various doses of alcoholic extract of rohituka, Aphanamixis polystachya (APE) was studied in mice transplanted with Ehrlich ascites carcinoma (EAC). Administration of 0, 0.125, 0.25, 0.5, 0.75, 1, 1.25 or 1.5 g/Kg body weight APE once daily for consecutive 9 days resulted in a dose dependent regression in the tumor mass and increase in tumor-free survivors. The greatest a...

and normal tissues. The nature and extent of such effects, however, depend on selected biological parameter (e.g., oxygen supply, cell cycle) and can be modified by chemical agents such as radiosensitizers, radioprotectors and chemotherapeutic agents. A precise control of the mode of action of the radiation is important in order to achieve the maximum effect on tumor tissue, while minimizing th...

متن کاملRole of plant metabolites in toxic liver injury.
Aphanamixis polystachya is a traditional medicinal plant of the Meliaceae family in India. A crude ethanolic extract of the leaf of this plant shows a beneficial effect on toxic liver injury. Its antihepatotoxic activity was evaluated on carbon tetrachloride (CCl4)-induced liver injury in a rat model. The assessment of hepatoprotective activity was evaluated by measuring the activities of aspar...
