Hence, Dexamethasone At Animals Of The Senior Group

Hence, Dexamethasone at animals of the senior group has less expressed braking an effect on . In other words, in process of ageing there is an increase of a threshold of sensitivity to braking influence of a working hormone of dexamethasone. This simple experience is surprising on the : it shows at once the mechanism and the fundamental law of biology - the law of a constancy of the internal environment, and its antipode - the law of a deviation of a homeostasis. Absolutely same phenomenon is observed and at the person. Here an example: at a group of persons which middle age was 56 years, the certain dose of dexamethasone has lowered level in blood on 39 %, and at young men (middle age 24 years) - - on 54 %. It means that in the middle age perceives regulating signals is worse, becomes to them less sensitive that inevitably leads to infringement of the law of a constancy of the internal environment. But infringement of this fundamental law of biology - a deviation from norm or illness for stability of environment is the main condition of preservation of "quality of a life" and the life of an individual.
