Characteristics of a healthy person.
Characteristics of a healthy person. Experimental pathology
Thus, for healthy people the most characteristic:
– dynamic equilibrium (stable equilibrium) of the body and the external environment;
– ability of organism to optimally adapt and function;
– preservation of complete physical, mental and social well-being of a person;
– full participation in employment and social activities.
In addition to the concepts of health there is also the notion of the norm of health. This term refers to the optimal form of human activity, providing maximum adaptability (adapt) to changing biological conditions and social life.
It can be argued . only a healthy body involving regulatory (nervous, endocrine, immune, humoral, genetic) and Executive (vital and important non-life) systems are able to maintain optimal homeostasis (homeokinesis), adaptability, resistance, performance, social and biological activity, vigor and life to ensure maximum lifespan.
On health status . as the disease, are significantly influenced by external and internal conditions, way of life, a state of heredity, Constitution, reactivity and resistance of the organism and the population, the environment, and the strength and effectiveness of the health system of their country of residence.
The main methods include General pathology experimental research method, clinical method of observation, comparative and pathological (evolutionary) method, the method of physical modeling, mathematical modeling, method of theoretical analysis.
Experimental method (experiment) in the development of pathology is very important. It allows to model (play) a variety of the disease, pathological condition, pathological process, pathological reaction to different animals in different conditions of external and internal environment.
Modeling of diseases and their components is carried out using various methods (tissue culture and isolated organs; off and transplantation of organs, acute and chronic experiment conducted on animals of different species, sex, age and condition, etc.) and a variety of techniques (physiological, including hematologic, electrophysiological, etc.; biochemical, morphological, including electron microscopic, histochemical, etc.; isotopic, immunological, etc.).
The advantages of the experimental method are the possibilities:
– dynamic the study of the origin, course and outcome of disease (from the beginning of the action of pathogenic factors on the organism under standard conditions until the death of the last);
– spread of disease and pathological processes for their constituents;
– objectively and in detail to compare the activity of a holistic patient-body systems and organs with the corresponding control (including with a healthy body);
– to specify the proportion and sequence of occurrence of the causal relationships at different course and outcome of diseases and pathological processes;
– to produce such effects on organisms animals that are unacceptable to impress a man;
– dynamic study of effects and mechanisms of action of various damaging factors and therapeutic means;
– objective study of the etiology, pathogenesis and manifestations of various diseases, pathological conditions, processes and reactions;
– identify General pathological (medical) and General biological regularities deployment of illness and extrapolating (transference) on their person, etc.
