Página 283 - ... immunity" has come to have a special and useful significance in relation to infection, intoxication, and other conditions of natural or acquired tolerance to obviously and seriously harmful agents. The process in both instances is, indeed, one of adaptation, and the newly acquired capacities of the serum are due to substances resulting from this adaptation.

Página 136 - SUMMARY. The results of these experiments may be summarized as follows : (1) Intraocular changes may be induced by deleterious substances in the circulation. (2) The effect of irritating material in the circulation induces, first, congestion of the ciliary body and iris and then vesicle formation in the ciliary region followed by fibrinous exudate into the anterior and posterior chambers. (3) Fibrinous and albuminous exudates have a predilection for the anterior chamber, depositing or forming on...
Página 295 - ... not chiefly antitoxic but bacteriolytic. In the light of the new knowledge of cytolytic sera, and the conditions under which these may be effective, the promise of serum therapy, so long limited to antitoxic immunity, seems now to .be definite and encouraging. Let me develop one of the new possibilities. We have seen in our review of haemolysis that hfemolytic serum heated to 56° C.
Página 100 - The lesions in primary tuberculosis of the adenoid are generally close to the epithelial surface and focal in character. Occasionally they may be found in deeper parts of the pharyngeal lymphoid tissue. 5. The pharyngeal tonsil may be a portal of entry for the tubercle bacillus and other microorganisms in localized or general infections.
