At the first symptom - quite often is the pain, arises later. at a cancer unlike always has steadily progressing character. For a cancer it is not peculiar plentiful and night . At appetite at the majority - of patients happens is kept, seldom comes considerable on-hudanie.

A Protective Barrier Of A Mucous Membrane: 1)
a protective barrier of a mucous membrane: 1) " a barrier", covering ; 2) the first line of protection - membranes of cages, 3) the second line of protection - a membrane mucous. The mechanisms stimulating secretion of hydrochloric acid: , , products of digested food, . - parasympathetic nervous system it is liberated in a stomach wall in the answer as on stimulation of wandering nerves (in a brain - phase of gastric secretion), and on local stimulation nervous textures at a food finding in a stomach (in a gastric phase of secretion) Acetyl-holin is an average on force a stimulator of production of hydrochloric acid and the strong - activator of liberation from G-cages. - the hormone, is allocated from G-cages department of a stomach and the top department of a small intestine, stimulates secretion of hydrochloric acid with cages and their sensitivity to parasympathetic and other stimulation. Clearing from G-cages parasympathetic stimulation, albuminous food, cause, amino acids, calcium, a mechanical stretching of a stomach, alkaline value in department.
