Methods of Pathophysiology
- Modeling: physical & formalized
- Clinical experiment
- Theoretical analysis
- Medical thinking
Modeling and its types
This method models disease & pathological states. It’s used to create logical models of pathogenesis and carry out computer modeling of diseases.
Types:
1. Physical (on animals, organs or cells) Experiment methods: a) removal & analysis of organs b) inclusion - introduction of a substance in excess c) stimulation d) tissue culture e) comparative pathology
2. Formalized - logic modelling used in learning process.
Modeling capabilities & limitations
Capabilities: Modeling is used to study the etiology and pathogenesis of diseases, method of diagnosis, disease development, treatment and prevention.
Limitations: Significant difference in species’ vital processes and important role of social factors in disease occurrence, development and outcome of human diseases.
Moral and ethical aspect of experimentation on animals
Experiment on animals should be made under strictly justified need using optimal species & number of animals with the use of painkillers.
Nosology is..
a doctrine about disease
Pathologic process is..
a complex of changes in tissues at infringement of the genetic program or interaction with the sickly factor of environment
Pathological reaction is..
inadequate answer/response of living system on physiological irritation.
Pre-existing disease is..
the weakening of some sanogenetic mechanisms preceding the promotion of disease development
Disease is..
a disturbance of normal activity under the influence of injurious agents with limitation of adaptation & ability to work.
Differences between Health & Disease
Health vs Disease
1. Wide vs Narrow range of functions
2. Sufficient vs Reduced amount of functional reserves
3. Lack of vs Presence of strong linkages between functions
4. Optimum vs Reduced adaptation to changing conditions
Classification of diseases
Cause: hereditary, acquired, infectious, non-infectious, traumatic, toxic
Clinic duration: flash-like (minutes - hours), acutest (hours to 3-4 days), acute (5-14 days), subacute (15-40 days), chronic (months to years)
Topographic-anatomic: renal, pulmonary, cardiac diseases
Age: Senile, newborn, childhood disease
Stages of diseases
- Latent period
- Prodromal period
- Period of expressed manifestations
- Outcome of disease
Disease outcomes
- recovery
- remission
- relapse
- complication
- chronic form
- death
Relapse
Renewed symptoms after their easing or elimination
