Abstract
|
|
|
|
The present investigation was undertaken to study whether tumor-associated macrophages of Daltons lymphoma (DL), a spontaneous transplantable T cell lymphoma can be activated to tumoricidal state by alcoholic extract of Tinospora cordifolia (ALTC). In vivo administration of ALTC (200 mg/kg body weight) in DL-bearing mice resulted in an enhanced RNI production and an augmented cytotoxic response of tumor-associated macrophages. Earlier we had reported that DL-bearing mice show a regression of thymus and an enlargement of spleen. In vivo administration of ALTC to DL-bearing hosts resulted in a decrease in the weight of spleen and counts of splenocytes along with an increase in the weight of thymus as compared to control DL-bearing mice. In vivo administration of ALTC in DL-bearing mice also resulted in an increase in the proliferation of splenocytes/thymocytes and BMC. The results of this study indicate that the ALTC upon in vivo administration in DL-bearing shows immuno-modulatory effects and thus may have clinical significance.
