Anatomic study demonstrates that the bodies of children, with increasing frequency as age
progresses, and the bodies of almost all adults contain lesions with characteristics indicating …

obtained following the injection of animals, considered tuberculous lesions that were
caseated to be potential sources of reinfection, and that for a lesion to be entirely healed it …

Evidence of tuberculous infection has been found in the lungs of all of fifty adults who have
been examined. Approximately one-half of all adults have encapsulated lesions of the lungs …

The term caseation is applied to the gross characteristics of the necrotic material commonly
seen intuberculous infection. This necrotic tissue can be easily removedfrom the …

In the present study previous attempts to correlate the pathological anatomy of tuberculosis
with the well-known data obtained by experiн ments have been continued. It is evident that …

The infection from the tubercle bacillus tends, through the formation of tubercles, to become
a focal infection. This tendency remains true, with but few exceptions, regardless of the …

The age incidence of focal tuberculous lesions of the lungs demonstrates that they have
their origin in most instances in childhood. Focal lesions which heal have been found at all …

This supplement is a record of a large number of anatomical studies on human tuberculosis
based on the Ghon conception of the primary focus, the author having worked in close …

In two previous papers (1) it was shown that primary tuberculous infection can restrict itself to
one or more parenchymatous foci in the lung tissue without lead ing to further spread to any …

Slight changes in area or of density of the hilum shadows are of no significance. If, however,
there appear areas of increased density at the root of the lung in the region of the nor-mal …
