Research reveals: The appropriate pressure can improve immunity
Pressure whether people feel a certain thing have difficulty, a certain the intersection of task and difficult finish and a certain potential response that threat made under environment greatly, should surge and react to also call. Examination, the competition, finish working index's, relative's passing away etc., were all a certain pressure. As the pressure will come, the hormone that some organs of the health will secrete many kinds of kinds is dealt with, even if Epinephrine of a major kind of main hormone among them, are commonly called as tense hormone. When the Epinephrine trickled to each part of the body through the blood vessel, some special physiological response was produced. For example, the heartbeat begins to accelerate, breathing begins to be rapid, muscles are tense, the thinking and vision become sharp, begin to sweat all over, disgusting and vomiting when being uneasy, serious, tense and uneasy and anxious.
The serious pressure can cause insomnia, depilates, gray hair, depression, senilis, even more serious disease and death, so people would all like to be far away from the pressure, or hope it is the better that the pressure is the smaller. However, the finding recently, to animal and people, it is not that the pressure is the smaller, the better, in certain environment and time, the appropriate pressure is the good thing, for example, can strengthen the ability to resist disease.
Bear certain mouse of pressure it resists ability of tumour to be stronger than mouse to have at all the pressure
Neurobiologist Matthew and Du Ning (matthew during) of the state university of Ohio of U.S.A. Research group last melanin tumour,it is last tumour not to last mouse. Then, suffer from these the mouse of cancer to divide into two groups and carry on controlled study. A group of mice put in a big cage, puts into more mice than usual, there are 20 mice at least, there are runners and toys in the cage at the same time. Another group of mice puts in the ordinary cage, there are only 5 mice in the cage, and there are no runners and toys.
Three weeks later, those mice put in the big cage especially assigned, its tumour has narrowed by half, tumour dwindles by 77% 6 weeks later, nearly dwindled by 80% than tumour of the little cage mouse. Moreover, in the trouble cancer mouse in the big cage, 17% of the mouse tumours totally disappear. Suprisingly, the benign change of tumour of these mice totally takes place under not accepting any treatment.
What took shape distinctly and compared with is, the trouble cancer mouse of the ordinary cage, its tumour continues growing. Meanwhile, carrying on the same experiment obtains the same result too after bringing out cancer of colon to the mouse. Tumour of mouse in the big cage has dwindled, and tumour of mouse in the ordinary cage continues growing.
Under the pressure, the interdynamic between brain - endocrine system and many kinds of hormone is main reasons for inhibiting tumour
Will tumour of the mouse narrow even disappear in the cage why is big? The important reason lies in the pressure. These pressures are in many aspects. First, there are place and apparatus of sports in the big cage, such as runner and toy, mouse's sport that this forces or lures intoes. This is a kind of behavioral pressure. Secondly, the relation between mouse's border is a kind of pressure too. Because there are many mice in the big cage, unavoidably conflicts, this forces the mouse participates in fighting and solve and conflict. Observe and find, some of the mice are bitten, some have left the scar that fight, because the partners are not friendly completely. This kind of situation is a behavioral pressure, it is the pressure of the psychology even more, will force the mouse to use intelligence and various ways to solve the dispute, even resort to force.
Certainly, the function of the pressure is through the rising or lowering to produce the effect of various tense hormone. Because the pressure exists, the tense hormone level in the body of mouse in the big cage has been improved, one of them kind is called thinly and plainly(leptin) Hormone obviously reduce. And the pressure mainly influences the behavioral centre of the mouse - -The brain, it is hypothalamic and of great impact especially to the brain. The hypothalamic energy balance of regulating the body, and maintain nervous system and endocrine system. Researchers find, the trouble cancer mouse in the big cage is after 2 weeks, it is source nutritive factor (bdnf) of nerve of the brain in it is hypothalamic The gene expression of the signal albumen code has been strengthened obviously, this means bdnf in the body of mouse in big cage increases.
Bdnf distributes over the central nervous system extensively, to neuronal surviving, division, growing to play an important role in development of central nervous system, and can prevent the neuron the biological effect of damaging the death, improving the neuronal pathologic state, promoting and is damaged neuronal regeneration and split up etc., and ripe centre and neuron of peripheral nervous system survive and normal physiological function need too. So, bdnf has played function in suffering from the inhibition of cancer mouse's tumour.
In order to tell tumour of the mouse is reduced not only because there is much run of mouse in the big cage (because there are runners) ,There is few run of mouse in the small cage (there is no runner) ,Researcher make, study further, find run of mouse grow, play less function inhibiting tumouring from. Because only there is increase without tense hormone of mouse of run, there is no increase of bdnf gene expression, there is no thin and plain and horizontal reducing in the body at the same time. So, under the function of the pressure, the interdynamic between brain - endocrine system and many kinds of hormone is to inhibit the main reason why tumour grows from.
Though this research is obtained through the mouse, it may be applicable to people. In the past, people all thought the cancer patient should avoid the pressure, but this research of the mouse proved the view in the past was not totally correct. The appropriate pressure has function of inhibiting cancer.
