Methods: The methanol root extracts of Mahonia leschenaultii(200 and 400 mg/kg) were given orally, and berberines(10 and 20 mg/kg) were injected intra-peritoneally for 14 successive days in tumor bearing mice. Hematological parameters(white and red blood cells, haemoglobin level, granulocytes, and agranulocytes), lipid parameters(total cholesterol and triglycerides), serum enzymes(serum glutamate pyruvate transaminases, serum glutamate oxaloacetate transaminases, and alkaline phosphatise) and mean survival and solid tumor growth were determined and compared with untreated mice. 5-fluorouracil(20 mg/kg) was used as a reference standard drug. Results: Mahonia leschenaultii and berberine reduced the hematocrit significantly. Furthermore, Mahonia leschenaultii and berberine improved the survival of mice significantly and restored the affected hematological and lipid parameters similar to the normal levels. Conclusions: These observations show a strong anticancer effect of methanol root extract of Mahonia leschenaultii and berberine in suppressing Dalton’s ascitic lymphoma cancer cell growth in a mouse model by controlling haematological, lipid, serum enzymes, and other derived parameters effectively.展开更多

The ethanolic extract of the whole dry plant powder contained numerous phytoconstituents, including flavonoids. The study was focused on the anticancer activity of Sargassum wightii in mice. METHOD: The ethanolic extract of Sargassum wightii(EESW) at two dose levels was used to examine the anticancer activity in mice using DAL cell lines to induce cancer. The body weight, viable and non-viable tumor cell count, mean survival time, increase in life span, and hematological parameters were observed for anticancer activity of EESW. RESULTS: The intraperitoneal inoculation of DAL cells in mice significantly increased cancer cell count. The decrease in the cancer cell number observed in the EESW-treated group cancer animals indicates that the test drug has a significant inhibitory effect on the tumor cell proliferation. Treatment with EESW also showed a significant decrease in tumor weight, and hence increased the lifespan of DAL-treated mice. In addition, EESW administration significantly restored the hematological parameters in DAL-treated mice. CONCLUSION: The present study results suggest that administration of extract offers enhanced antioxidant potential. Therefore it can be concluded from this study that EESW possesses anticancer activity.展开更多
