>Write articles : The Great Britain and America scientist found the gene which controls the biological clock
Great Britain and America scientist's union was here a few days ago>Write articles and claim, they have already found and handled the gene of the biological clock trend in the brain of the experimental mouse on the periodical " per1" ,And basically find out biological clock " L Natural disposition " ,Can produce the medicine that can relieve the time difference effectively soon according to the thinking of such research, and not normal making breakthrough progress at the the intersection of old age and research of the disease that dull-witted and endocrine regulation,etc. have contacts with disorder of biological clock in cancer, mood further. Except the enormous use prospect in the medical field, understand operation principle and way of the brain biological clock can help the pilot, media employee,etc. to need people on night duty to keep the sober and good state of mind frequently too.
As everyone knows, the system that the department is in charge of time in the human body is known as " L The physiological rhythm " ,Biological clock thatting is to be commonly called as. It helps our health to maintain a basic operation law, when to have a meal, sleep, wake up; When will some other functions of the body be carried on .
The scientist introduces to claim, control that area of the biological clock to be named in the brain " L Look at and have cores alternately " (SCN) ,Like all mammals, the straight place too of that area where SCN belongs to is above the palate on the oral cavity in the human brain, it is very difficult for the technological means of what Israel have now to do the experiment in that area of the human brain, so this research can only go on on experiment mouse. The scientist says, through looking for untiringly for many years, they found totally different cells between two kinds of functions in the area of SCN at last, the ones that control mammalian biological clock " per1" The gene is being just found " L Biological clock cells " R China, and another kind " L It is not biological clock cells " R Function present unable to find out.
Another one of this research breaks through lying in importantly, it has totally subverted the supposition to the biological clock activity in the past of medical circle. The medical circle thought, two kinds of cells of SCN will have sent out the electric pulse in the daytime all the time to regulate the human clocking in the past, will come down slowly in the evening.
And the research this time verifies, these two kinds of cells did not begin to concentrate on launching the electric pulse since the time of at dusk, stop in the evening, the second the sky and the sun continue launching while appearing, SCN cells will not launch the electric pulse during the whole daytime, an activeness state that and just keep it. This seem you play one car, engine roar, thunder too, step on the intersection of oil and the intersection of door knob and bus, hold, go out the same.
Mathematician, university of Michigan, doses of professor have an optimistic view of the prospect of research very much, he says: " It is known how SCN transmits the biological clock signal, we can regulate him, then make breakthrough progress in the making a diagnosis of all diseases related to disorder of biological clock.
