constitutional dyscrasia, or diathesis; and its terminations are
induration, hypertrophy, tumefaction, suppuration, ulceration,
fatty degeneration, the formation of cold abscesses, and casea-
tion. The local symptoms differ from those of the acuter form
only in the degree of severity.
Terminations of Inflammation.—According to the present knowl-
edge of this subject, inflammation terminates— ist, By Resolu-
tion ; 2d, By Suppuration; 3d, By Formation of New Tissue; 4th,
By Gangrene or Local Death— Necrosis. When the inflammatory
process terminates by resolution., all of the symptoms gradually
diminish and disappear, and the affected tissues resume their
normal condition. Such a result is generally due to the mild
character of the injury, and the progress of the inflammation.
Resolution is the most favorable ending of inflammation and is
established as soon as the blood which circulates through the
vessels restores their walls to a healthy state.
When the inflammatory process terminates by suppuration.^
there is a loss of substance, and after the discharge of the pus,
a more extensive process of repair is required to produce a heal-
ing of the wound by the growth of granulation tissue, and the
formation of the cicatrix. (See Suppuration and Abscess.)
When the inflammatory process terminates by the formation
of new tissue., the new growth is produced by inflammation
either by the union by first intention, or by the development of
granulations, which become organized into a cicatrix.
When the inflammatory process terminates in gangrene or local
death., the effort of the inflammation toward repair has failed,
either on account of the functions of the capillaries and the con-
nective tissue becoming impeded to such a degree as to render
inoperative the resources of the organisms, or because of certain
conditions arising at a later period which have obstructed the
reparative effort and caused the parts to lose their vitality.
The termination of the inflammatory process by gangrene de-
pends upon the degree and nature of the lesion, and the inability
of the capillaries and arteries to maintain the local circulation.
The impairment of the vitality of the blood vessels causes stasis
and thrombosis to occur, and as soon as actual death takes place,
