The pathology of gastric ulcer sums up _'s general knowledge
Introduce several kinds of main theories as follows now:
( 1) Wound theory: Someone thinks stomach and duodenum primary damage are reasons why ulcer forms. These factor organic tool instrument, warm and hot, chemical stimulus damaged. It makes the mucous membrane of stomach damage that these are stimulated; Become " since the body is digested " Starting point,then develop into ulcer.
This theory has explained that causes the external cause of ulcer, the obviously mistake is not to pay attention to even more important internal cause. To say, factor of those wounds, it is only an external cause, could cause ulcer only through certain internal cause.
( 2) Blood vessel theory: Some think the coat of the stomach will not be corroded by the gastric juice when blood supplt is normal. When the blood vessel of intestines and stomach has pathological change, make some the intersection of stomach and mucous membrane ischemic necrosis and cause ulcer.
( 3) Inflammatory theory: See the stomach or duodenum mucomembranous inflammation pathological change at the same time according to the finding, 100% of the ulcer, and this kind of pathological change takes place before ulcer take shape. So think, gastritis form the first stage of ulcer, typical ulcer will happen in the ones that continue.
( 4) Digest the theory: Have a history of more than 100 years already, it degree increase and peptic increase of quantity place above the other things the intersection of gastric juice and increase, gastric acid of quantity. Think the the intersection of gastric juice and increase of digestion power, the intersection of ulcer and basic factor that disease take place. So called this disease in the past " Peptic ulcer " .
But the ulcer patient is not that the gastric acid increases, some patient gastric acid is normal and even scarce. And some gastric acid very tall person, ulcer might not happen. So have certain reasons to digest the theory, but can't expound various intricate problems related to the fact that a disease happen.
( 5) Uneven theory of the nerve of plant: The nerve function disorder of the plant is related with the emergence of ulcer. This shortcoming with basic theory is to misjudge influence of the environmental condition of the external world, only emphasize isolatedly that has broken away from the influence of the higher nervous activity from function on this disease of the automatic nervous system, it is obviously one-sided.
( 6) Cortex viscera theory: Can often see because the case that the spiritual mood factor brings about in ulcer or aggravates on clinic.
Cortex the intersection of viscera and the intersection of founder and the intersection of shellfish and Ke of theory think cerebral cortex function disorder of state the leading factor for course of of ulcer. The activity obstacle of cerebral cortex, make the normal relation between bottom cortex and cortex lack proper care, cause the sympathetic nerve to be inhibited, the tension of parasympathetic nerve strengthens and forms ulcer.
( 7) Infect the theory: Since people re-recognized spiral shell's bacillus of pylorus in 1983 ' Abbreviated as HP) And then, a fundamental change that the pathogenesis of peptic ulcer has arisen. Most experts think the main reason why HP is peptic ulcer at present. It is obvious that it should be considered to be a kind of infectious disease to digest ulcer, after HP is eliminated, peptic ulcer can effect a radical cure.
( 8) Other theories: Besides above-mentioned several kinds of theories, organized acidotic theory, vitamin lack theory, neural nutrition theory, allergy theory, hereditary theory, endocrine theory etc.. These theories all have certain foundations, but there are many one-sideds too.
We think, the pathogenic factor of ulcer is not one kind, but there are many kinds of factors.
Ulcer take shape, depend on, facilitate factor and to resist ulcer, result that factor struggle each other of ulcer.
