  • Inhibitory effects of synthetic and natural colorants on carcinogenesis VI
    Patent number: 6267946
    Abstract: A method of reducing the percentage of Epstein-Barr virus genome-carrying cells which exhibit Epstein-Barr virus early antigen induction, wherein the Epstein-Barr virus genome-carrying cells have been cultivated in the presence of a tumor-promoting chemical and/or a tumor-inducing chemical. The method is performed by: a) cultivating Epstein-Barr virus genome-carrying cells in the presence of a tumor-promoting chemical and/or a tumor-inducing chemical; and b) treating the Epstein-Barr virus genome-carrying cells with a synthetic anthraquinone colorant containing a sulfonated phenylamino group. The colorant is effective to reduce the incidence of Epstein-Barr virus early antigen induction in the cultivated Epstein-Barr virus genome-carrying cells.
    Type: Grant

    Date of Patent: July 31, 2001
    Inventor: Govind Kapadia
  • Inhibitory effect of synthetic and natural colorants on carcinogenesis
    Patent number: 6228365
    Abstract: A method of reducing the incidence of pulmonary tumor formation in animals exposed to a tumor-promoting chemical or a tumor initiating by providing a group of animals which have been exposed to a tumor-promoting chemical or a tumor-initiating chemical with drinking water containing betanins. Preferably, the betanins are obtained from a beetroot extract.
    Type: Grant

    Date of Patent: May 8, 2001
    Inventor: Govind Kapadia
  • Inhibitory effects of synthetic and natural colorant on carcinogenesis VIII
    Patent number: 6225296
    Abstract: A method of inhibiting Epstein-Barr virus early antigen induction in Epstein-Barr virus genome-carrying cells which have been cultivated in vitro in a medium containing at least one chemical selected from the group consisting of tumor-inducing chemicals and tumor promoting chemicals by adding an effective amount of a synthetic colorant to the medium, wherein the synthetic colorant is an aromatic azo dye.

  • Inhibitory effects of synthetic and natural colorants on carcinogenesis III
    Patent number: 6080411
    Abstract: A method of reducing the incidence of splenomegalia induced by ultra violet radiation in mammals by exposing a group of test mammals to intense ultraviolet radiation, where the exposure is repeated at regular intervals over a test period such that the cumulative radiation exposure per mammal is sufficient to cause an increase in an average spleen size in a group of unprotected mammals; and administering drinking water containing a defined concentration of betanins to the group of test mammals during the test period, said defined concentration being sufficient to prevent such an increase in average spleen size.
