en پژوهشي Research Article The aim of this study was to evaluate antitumour activity of the roots of Hibiscus tiliaceus Linn. against Dalton’s Ascitic Lymphoma (DAL) in Swiss albino mice. A significant enhancement of mean survival time (MST) of H. tiliaceus treated tumour bearing mice was found with respect to control group. H. tiliaceus treatment was found to enhance peritoneal cell counts. When these H. tiliaceus treated animals underwent intraperitoneal (i.p.) inoculation with DAL cells, tumour cell growth was found to be inhibited. The results indicated that, H. tiliaceus treated group were able to reverse the haematological parameters, protein and Packed Cell Volume (PCV) consequent to tumour inoculation with in fourteen days after the transplantation. 123 0 http://ijpt.iums.ac.ir/browse.php?a_code=A-10-100-157&slc_lang=en&sid=1 Anbu Jeba Sunilson 1003194753284600510 1003194753284600510 No Syam Mohan 1003194753284600511 1003194753284600511 No Mustafa Ali Mohamed 1003194753284600512 1003194753284600512 No John Thomas 1003194753284600513 1003194753284600513 No Anita Gnana Kumari 1003194753284600514 1003194753284600514 No
