10.22376/ijpbs.2019.10.1.p1-12 Volume 4 Issue 3 2013 (July - September) The present study aims to evaluate the antitumor activity of ethanol extract of whole plant of lessThan i greaterThan Polycarpaea corymbosa lessThan /i greaterThan on DAL model in Swiss Albino miceThe following parameters: tumor volume, viable and non viable cell count and life span of host were evaluated DAL bearing in swiss albino mice. The above said parameter were also evaluation by administrating ethanol extract of whole plant of lessThan i greaterThan Polycarpaea corymbosa. lessThan /i greaterThan The results showed a decrease in tumor volume and cell viability. Hematological studies revealed that, the Hb count decreased in DAL treated mice, whereas, it was induced by the drug treated animals and showed an increase in Hb near to normal levels. The results suggested that, the extracts of whole plant of lessThan i greaterThan Polycarpaea corymbosa lessThan /i greaterThan exhibited significant antitumor activity on DAL bearing mice.
