    Abstract:
    Co-cultivation of splenocytes with cis-dichlorodiamine platinum (II) treated tumor cells generate cytotoxic splenocytes, which when injected into normal mice, render them resistant to tumor challenge. Significant increases in mean survival time and 33% of tumor free survivals were observed in mice exposed to a tumor challenge on the 10th day after injection of sensitized splenocytes. Splenocytes peritoneal exudate cells obtained after in vivo immunization of mice with cis-dichlorodiamine platinum(II) treated cells retarded tumor growth in vivo when injected in different combinations in tumor bearing mice. Maximum survival time of tumor bearing mice and 20% tumor free survivals were observed when the animals were injected with a combination of immune splenocytes and normal peritoneal exudate cells. The increase in the number of macrophages of immunotherapeutically treated mice suggests that host macrophages have been activated. Splenocytes and macrophages obtained from immunotherapeutically treated mice showed an increase in cytotoxicity against tumor cells in vitro.
