title: Effect of Biophytum sensitivum on cell-mediated immune response in mice.
abstract: Effect of Biophytum sensitivum on cell-mediated immune response was studied in normal as well as Ehrlich ascites tumor bearing BALB/c mice. Administration of Biophytum sensitivum significantly enhanced the proliferation of splenocytes, thymocytes and bone marrow cells by stimulating the mitogenic potential of various mitogens such as Lipopolysaccharide (LPS), Concanavalin A (Con A), Phytohaemagglutinin (PHA) and Poke Weed Mitogen (PWM). Natural killer (NK) cell activity was enhanced significantly by Biophytum sensitivum in both the normal (43.6% cell lysis on day 5) and the tumor bearing group (48.2% cell lysis on day 5), and it was found to be earlier than tumor bearing control animals (maximum of 13.4% cell lysis on day 9). Antibody dependent cellular cytotoxicity (ADCC) was also enhanced significantly in both Biophytum treated normal (35% cell lysis on day 7) as well as tumor bearing animals (40.2% cell lysis on day 7) compared to untreated control tumor bearing animals (maximum of 12.3% cell lysis on day 11). An early antibody dependent complement mediated cytotoxicity (ACC) was also observed in the Biophytum treated normal (22.6% cell lysis, on day 15) and tumor bearing animals (26.4% cell lysis, on day 15). Results of our present study suggest the immunomodulatory property of Biophytum sensitivum.
