Antitumor and Immunomodulatory Activities of Peganum harmala Extracts

This study was designed to search the antitumor potential of Peganum harmala methanolic extracts and to evaluate their role in retardation the immunological side effects pre-and post-treatment which were carried out on 30 Albino male mice and included total and absolute count of leucocytes, micronucleus formation and phagocytic index of peritoneal cells. Our study showed that P. harmala derivatives have considerable antitumor activity with high efficacy in immobilization of the immunological side effects evoked following treatment with antitumor drug. In conclusion, P. harmala possess antitumor activity increases with concentrations increasing. Pre-treatment with these extracts exert higher retardation to the side effects than post-treatment.
