Physiological potential of beta-carotene in prolonging the survival of the host bearing transplantable murine lymphoma.

beta-Carotene, when supplemented in diet, has been found to increase the survival period of mice bearing a transplantable tumor, Dalton's lymphoma. Tumor cell-count, body weight pattern, hematological parameters like total count showed marked alterations in a dose-responsive manner with beta-carotene administration when compared to their untreated counterparts. Decreased tumor cell proliferation is also reflected by increased hemoglobin levels of the host.
