Theme 2: " GENERAL STUDY ABOUT NOSOLOGY, ETIOLOGY AND
PATHOGENESIS (the SEMINAR)".
Actuality of the theme.
Teaching about disease, or the general nosology (from greek “nosos” - a
disease), belongs to belongs to the most old problem of medicine since. States of
health and disease, as a rule, are interleaved and go one in another often without
observable borders. For physician it is important to have general criteria, which
gave him possibility faultless to distinguish health from disease.
Study about etiology or reason and condition of the development of the
diseases, belongs to the oldest problem of medicine since because the first question,
with which the physician is confronted at examination of sick, concerns its reasons.
Find the reason a disease – it means to find the way to its treatment and preventive
maintenance. However, this question is not from lights often. Special etiology
studies the concrete reasons and condition of the arising the separate diseases.
Thereby, teaching about reason of the origin disease (etiology) is naturalscientific base one of the most important principle of medicine - its preventive
directivity.
Studies about pathogenesis belong to the most actual problems of modern
medicine. In fact only understanding general mechanism of development, motion
and outcomes of diseases, it is possible to consider one a «thinking» doctor.
The sequence of changes is determined in an organism for every disease,
cause-effective relations appear between different structural, metabolic and
functional changes are determined at the same time. In other words factors which
assist subsequent development of illness are determined.
The analysis of pathogenesis requires the clear understanding of role of
etiologic factor in pathogenesis, and also correlation between general and local,
structural and functional. Understanding of cause-effect relations and ability to see
and select the «main link» of pathogenesis will allow the doctor of any profession
to liquidate a pathological process and accelerate the offensive of favorable
consequences of illness.
General purpose of the lesson.
1. To know how to define biological and social essence of disease, the general
regularities of dynamic of its development.
2. To learn the role of the reasons and conditions in development of disease.
3. To learn the general conceptions of pathogenesis, to interpret the mechanisms
of development of pathological processes correctly.
For this it is necessary to know (the concrete purposes):
1. Explain the basic concepts of general nosology: health, disease, pathological
process, typical pathological process, pathological reaction, pathological
condition, etiology, pathogenesis.
2. Explain the basic concepts of etiology: causal factors, risk factors, and conditions
of disease development.
8
3. Analyze various options for the cause-effective relationships in pathogenesis.
4. Analyze of pathological phenomena in the pathogenesis: adaptive-compensatory,
general and local, specific and nonspecific, leading to main link of
pathogenesis.
5. Evaluate the importance of modern methods of research (experimental and
clinical) for the pathophysiology.
For realization of purposes of lesson it is necessary to have the base
knowledges-skills.
1. To have a notion about correlation the weltanschauung and philosophy (the
world, its structure, types) (department of the social sciences - discipline –
philosophy).
2. To know philosophy of the Ancient East, China, Greece, Rome, Middle Ages
and Renaissance (department of the social sciences - discipline – philosophy).

6. To have a conception about problem of the person in philosophy (the psyche
and consciousness; biological, social and spiritual at person) (department of the
social sciences - discipline – philosophy).
7. To have a notion about such philosophical conceptions, as: matter, motion,
space and time (department of the social sciences - discipline – philosophy).
8. To have a notion about general-logical methods: abstracting, analysis and

social sciences - discipline – philosophy).
9. To know the methods of the empirical cognition: scientific observation,
scientific experiment, empirical modeling (department of the social sciences discipline – philosophy).

Theme
3:
PATHOGENIC EFFECT OF THE ENVIRONMENTAL
FACTORS (mechanical factor, ionizing radiation, barometric
pressure, high and low temperatures)
Actuality of the theme.
Ionizing radiation is radiation, which interaction with the environment
results in ionization with the formation of electric charges with different signs.
Ionization and accompanying it excitement of atoms and molecules is a starting
mechanism of processes that results in the development of the radial damage of
biological structures of cells, tissues, organs, systems of the whole organism.
Mechanical trauma is one of the main reasons of hospitalization and
before the proper time disability. According to the data of the World Organization
of Health 250 thousands of peoples perish from incidents on the roads and more
than 10 millions get injuries every year.
A man feels the influence of diminished barometric pressure at climbing in
mountains or at flight in aircrafts (at decompression of airplane cabin). The
influence of the high barometric pressure at immersion into water.
Thermal factor is of great importance in the development of pathologic
processes. Overheating and super cooling result in changing of thermoregulation,
disorders of different organs and systems of the organism.
Knowledges of the mechanisms of hyper and hypothermia are necessary
for working out the methods of treatment and prophylaxis of these pathological
processes.
Electric current is one of the most dangerous environmental factors that
has a pathogenic influence and results in the development of the extreme states.
The wide use of the latter in industry in everyday life in natural conditions with

Theme 4: PATHOGENIC EFFECT OF THE ENVIRONMENTAL
FACTORS (chemical, biological, social and psyhical).
Among the pathological environment factors chemical substances take one
of leading places. Constant decreasing of their number is observed. Now more than
five million different chemical substances have been registered in the world and
about two thousand new ones are synthesized every year. A man widely enough
contacts with 60 – 70 thousand chemical substances. Scientific and technical
progress is associated with steady decrease of mass of chemical substances that get
in an environment.

Theme 5: ROLE OF REACTIVITY, RESÍSTANSE AND SMPh IN
DEVELOPMENT OF PATHOLOGY. IMMUNOLOGICAL
REACTIVITY.
Actuality of the theme
Notion of reactivity firmly entered in practical medicine, helping objectively
to estimate being of patient. Reactivity of an organism is one of important factors
of pathogenesis of disease, as pathological reactivity is characterized by the
decrease of adaptation properties of an organism.
Any pathological process changes reactivity of an organism. At the same
time the change of reactivity, that exceeded physiological borders, can become the
basis of development of disease. Therefore the study of reactivity and its
mechanisms has the important value for understanding of pathogenesis of diseases
and purposeful medical treatment.
Immunological reactivity is the issue of the day of modern medicine.
Study of immunity, as firmness to the infectious diseases, beginning is
fixed to L. Paster, I.I. Mechnicov, drove to our time to opening of mechanisms of
immunological reactivity that is carried out by competent immune tissue. Support
of antigen homeostasis in an organism both to infectious is the basic function of it
and to the uninfectious antigens.
The cellular and humoral immunological reactions are, from one side, by
the basis of protective mechanisms at a different pathology, and from the second by the basis of allergy. Different pathological processes develop in the case of
insufficiency or discoordinated functions of the immune system.
Therefore study of structure and functions of cells, which take part in the
immune answer, finding out of type of inheriting of immunodeficiency syndromes,
mechanisms of their development, conducting of adequate treatment has big value
in the system of preparation of future doctor.
General purpose of the lesson - to learn the main types of reactivity of an
organism at pathological processes; to expose a role of the system of mononuclear
phagocytes (SMPh) in the mechanisms of reactivity; to learn the mechanisms of
development of immunodeficiency and methods of their correction
For this purpose it is necessary to be able (concrete aims):
1. To learn concept of reactivity, to understand its role in support of homeostasis
and development of pathological process.
2. To know kinds and main mechanisms of reactivity.
3. To know the character of reactivity of child's organism.
4. To be able to explain of definition "resistance of an organism" and expose the
main mechanisms of specific and unspecific resistance.
5. To be able to describe the value of SMPh in the mechanisms of reactivity.
6. To analyze mechanisms of immunological reactivity.
7. To analyze features of forming of immunological reactivity in child's age.
8. To explain violations, which lead to insufficiency of the immune system.
41
9. To explain methods of correction of insufficiency of a different immunological
states.
For realization of aims studies base knowledge-abilities (practical
knowledge) are needed:
1. Nervous, endocrine and humoral mechanisms of reactions of an organism on
action of external environmental factors (normal physiology).
2. Reactions from the cardiovascular system on the physical loading (normal
physiology).
3. Reactions from the thermoregulatory system on action of thermal and cold
factors (normal physiology).
4. Reactions from the external breathing system on the change of barometric
pressure of oxygen in air (normal physiology).

Actuality of theme.
Recently, the disease occurrence in which genetic factors play an
important role, causing an increased interest in communication because of the fact
that the structure of morbidity, they acquire a large share. Scientific basis in the
ratio becomes hereditary and acquired human pathology.
Constantly expanding amount of information about the mutagenicity of
environmental factors.
Great importance of the disease, in which the matter of genetic
predisposition (peptic ulcer, hypertension, atherosclerosis, diabetes, allergies and
many others). Treatment and prevention of them will be based on the role of
heredity.
Noteworthy diseases that arise during fetal development under the
influence of pathogenic factors on pregnant women.

4. Inherited propensity to diseases.
A gene is the unit of chromosome. Genes are linearly located in chromosomes.
A place which rank a gene in a chromosome is named locus.
Genotype is - aggregate (total) genes of an organism.
Alleles are genes, which rank the same locus in the homologous chromosomes,
hut they causedphenotypic differences.
Phenotype is the aggregate of the properties of organism, both inherited
conditioned and conditioned by influencing of external emnronment.
Phenocopy is changes which arose up under action of external environment,
and lo o k like w ith the changes concerned with any genotypic factor.
I n the nuclei of cells of woman's organism, unlike masculine there is sex
chromatin (as lum p under the membrane of nucleus). Number of the lumps of
sex chromatin is equal amountsX-chromosome minus 1.
Analogue of sex chromatin is Barr's body (on the nucleus of neutrophil as a
drumstick).
Constitution it is the complex of morphological, functional and psychical
features of an organism that determine his reactivity and are formed on the
inherited basis under at i of external environmental factors.
