10.22376/ijpbs.2019.10.1.p1-12 Volume 6 Issue 2 2015 (April - June) The main aim of the present study is to evaluate an Antitumor activity of Aqueous extract of leaves of lessThan i greaterThan Holoptelea integrifolia lessThan /i greaterThan (HIAQ) in EAC induced Ascites tumor model: An In-vivo study. The Aqueous extract of leaves of lessThan i greaterThan Holoptelea integrifolia lessThan /i greaterThan was prepared by cold maceration technique. Acute toxicity test was performed using Swiss albino rats before starting the in-vivo anticancer activity, were the MTD was more than 5000mg/kg. The in-vivo Antitumor activity was assessed by administering 250mg and 500mg/kg of Aqueous extract of lessThan i greaterThan HI lessThan /i greaterThan leaves, orally for 9 days and Cisplatin (3.5mg/kg, i.p., Single dose). Various parameters like Change in body weight, Mean Survival Time, Percentage Increase in Life Span, Hematological & Biochemical parameters were assessed. All the parameters were considerably restored towards the normal values. The in-vivo activity of lessThan i greaterThan HI lessThan /i greaterThan 500mg/kg was shown more significant results than 250mg/kg. Hence 500mg/kg was taken for combination study with standard drug Cisplatin. PRAMOD SG, JAYANTHI MK, MRUTHUNJAYA K, MANJULA SN AND SUNIL KUMAR.
