Kefir and cancer, the antitumoral properties of kefir grain.
I was doing a search on patents involving kefir and found this one.
Patent # US4229440: Pharmaceutical composition containing the polysaccharide KGF-C as active ingredient.
KGF-C is obtained by grinding kefir grain, adding water to the ground kefir grain and heating, homogenizing the mixture and centrifuging it, adding ethanol to the obtained supernatant to obtain a precipitate, dissolving the precipitate into water, purifying the obtained liquid and freeze-drying the remaining liquid. The obtained KGF-C is soluble in water and is composed of polysaccharide as principal component and contains a very small amount of nitrogenous component, and, as sugar composition, is composed of glucose and galactose in the ratio 1:1.
This KGF-C has strong antitumor action by oral administration.
The most important feature of the antitumor agent of the present invention is that it has scarcely any toxicity and has a very high antitumor activity and is able to be administered orally. In the case of oral administration, adverse reaction is generally low and therefore administration of this type is desirable, but there has heretofore scarcely been any carcinostatic substance which can be orally administered, and therefore the present invention is a very unique one. Since it is a matter of course that the antitumor agent of the present invention can be parenterally administered, it can be said that this antitumor agent is a very new type of medicine which has not been present so far and shows a notable inhibitory activity in either the case of oral or parenteral administration. As will be apparent from the facts described hereinafter, it has been found that the present antitumor agent has a notable inhibition against solid transplantable cancer and solid transplantable tumor even by oral administration as a result of animal experiment.
I think the KGF stands for Keratinocyte Growth Factor but I don't know. All I know is that the probiotic cultures in kefir built that polysaccharide.
Note: This patent has nothing to do with Lifeway. But has everything to do with kefir. And kefir is Lifeway Foods.
