Pagina 200 - Inflammation may be defined as a succession of changes which take place in a living tissue as the result of some kind of injury, provided that this injury be sufficient immediately to destroy its vitality.
Pagina 178 - It is the general character of the cells, together with their mode of distribution in the meshes of a fibroid stroma, that determines the nature of the growth to which they belong. " The appearance presented by these cells grouped within the alveoli of the cancer sometimes closely simulates in the earlier stages of growth that of simple adenoma," only here the cells are less irregular and more like the normal.
Pagina 212 - Inflammation is the aggregate of those results which manifest themselves in an injured part as the immediate consequences of the injurious action to which it has been exposed.
Pagina 177 - The cells are characterized by their large size, by the diversity of their forms, and by the magnitude and prominence of their nuclei and nucleoli. In size they vary from ^ to j^x, of an inch in diameter, the majority being about five times as large as a red blood-corpuscle.
Pagina 177 - In size they vary from ^ to j^x, of an inch in diameter, the majority being about five times as large as a red blood-corpuscle. They are round, oval, fusiform, caudate, polygonal — exhibiting, in short, every diversity of outline. The nuclei, which are large and prominent, are round or oval in shape, and contain one or more bright nucleoli.
Pagina 192 - In these tumors the epithelial elements are similar to those of the mucous membrane from which they grow. They are cylindrical in shape, and are arranged perpendicularly to the walls of the alveoli in a manner precisely analogous to that of the columnar epithelium on the mucous surface (Fig.
Pagina 248 - ... Septicaemia appears, therefore, to differ from simple traumatic fever mainly in this — that in it the infective process is one of much greater intensity. No sharp line of demarcation, however, can be drawn between the two. The clinical phenomena of septicaemia, as observed in man, are characterized not only by pyrexia, but also by vomiting, diarrhoea, muscular enfeeblement, affecting particularly the heart and respiratory muscles, and ultimately a condition of collapse which tends to terminate...
Pagina 387 - Longitudinal section of the ligatured end of the crural artery of a dog — fifty days after the application of the ligature. Showing the newly formed vessels in the thrombus and their communication with the vasa vasorum. Th, thrombus; M, muscular coat; Z, external coat and vasa vasorum. X 20. (O. Weber.) The injury to the endothelium may arise by traumatism, as by ligature during operation (Fig.
Pagina xix - By disease is understood some deviation from the state of health ; a deviation consisting for the most part in an alteration in the functions, properties, or structure of some tissue or organ owing to which its office in the economy is no longer performed in accordance with the natural standard.
Pagina 404 - ... in one of the vessels beyond the circle of Willis, because here the circulation cannot be readily restored by the collateral vessels. Softening, however, does not necessarily follow the blocking of a cortical artery, for communication between these branches is freer than is often supposed.
