There seems to be a balance maintained between the restriction of
disease by prevention and the increased influence of social conditions
which are in themselves factors of disease. Preventive medicine seems
to have made possible, by restricting their harmful influence, the
increase in industrialism, in urban life, and in the
intercommunications of peoples. The most important aid in the future
to the influence of preventive medicine must be the education of the
people so that the conditions of disease, the intrinsic and the
extrinsic causes and the manner in which these act, shall all become a
part of general knowledge, and the sympathy of the people with health
legislation and their active assistance in carrying out measures of
prevention may be obtained. The effect of social conditions on disease
must become more generally recognized.
GLOSSARY
ATROPHY--A condition of imperfect nutrition producing diminution in
size and loss of function of parts.
BERTILLON--A French anthropologist who devised a system of
measurements of the human body for purposes of identification.
BLOOD-PLASMA--The fluid of the blood.
CELL--The unit of living matter. Living things may be unicellular or
composed of a multitude of cells which are interdependent. The
general mass of material forming the cell is termed cytoplasm. In this
there is a differentiated area termed nucleus which governs the
multiplication of cells. In the nucleus is a material termed chromatin
which bears the factors of heredity.
CHEMOTROPISM--The influence of chemical substances in directing the
movement of organisms.
EXUDATE--The material which passes from the blood into an injured part
and causes the swelling.
FIBRIN--The gelatinous material formed in the blood when it clots.
HAEMOGLOBIN--A substance which gives the red color to the blood; by
means of its ready combination with the oxygen of the air in the lungs
this necessary element is carried to all parts of the body.
INFLAMMATION--Literally a "burning"; the changes which take place in a
part after injury.
LYMPH--The fluid which is contained in the lymphatic vessels--nodes.
Circumscribed masses of cells connected with the lymphatic vessels.
OSMOSIS--The process of diffusion between fluids of different
molecular pressures.
SPORE FORMATION--A mode of reproduction in lower forms of life by
which resistant bodies, _spores_, are formed. These have many
analogies with the seed of higher plants.
SYMBIOSIS--A mutual adaptation between parasite and host.
TRANSUDATION--The normal interchange of fluid between the blood and
the tissue fluids. The material interchanged is the transudate.
TROPISM--The influence of forces which direct the movement of cells.
ULTRA-MICROSCOPE--A form of microscope which by means of oblique
illumination renders visible objects so small as to be invisible with
the ordinary microscope.
VIRUS--A substance either living or formed by living things which may
cause disease.
