An orally applicable fermentation product of wheat germ containing 0.04% substituted benzoquinone (MSC) has been invented by Hungarian chemists under the trade name of AVEMAR. Oral administration (3 g/kg body weight) of MSC enhances blastic transformation of splenic lymphocytes in mice. The same treatment shortens the survival time of skin grafts in a co-isogenic mouse skin transplantation model, pointing to the immune-reconstructive effect of MSC. A highly significant antimetastatic effect of MSC has been observed in three metastasis models (3LL-HH, B16, HCR-25).
