Quoted message said:Well it is accepted in science that enzymes are absorbed intact orally..

The above, like the pig abstract, demonstrate that if proteins are small
enough they can be absorped, apparently at least the one above falls into
that category. Being able to generalize that example to all enzymes is
dubious and not yet shown. In the current question is that of those of
the pancreas, and by definition any others not included above. The beauty
of the pig abstract was that their pancreas was removed so any possible
level in the blood after oral intake of enzymes produced by it would have
to be external. In the specific instance of enzymes of the pancreas, on
which the cancer theory depends, it has been demonstrated they are not
absorbed. For that reason the mice abstract shows only that intake of
enzmes from the pancreas by water seemed to have an effect on the course
of the disease while not showing those enzymes showing up in the blood.
They were human cancer cells transplanted in the mice, it is just as valid
a theory that the enzymes in the gut caused some differences in hormones
which affected the course of the disease in a context of cell rejection.
Btw, the above abstract still needs to exclude other possible reasons that
blood levels of the enzyme rose in correlation with the dose, apart from
the size issue which relates to all proteins. Those same enzymes are
produced by the body all the time, the normal source of them and not food.
Again, we must exclude the possibility that presence of isolated enzymes
in the gut does not cause an increase of internal production. The only
support this cancer treatment will get is if it shows promise in the
current trial, and how that came to be is an intresting story in itself.
