Acute inflammation of various types, suppuration, granulation-tissue formation, &c., represent some of the complex resulting processes.
Thus Krawkow and Nowak, employing the frequent subcutaneous injection of the usual organisms of suppuration, have induced in the fowl the deposition within the tissues of a homogeneous substance giving the colour reactions of true amyloid.
Nowak, however, found later that he could generate it where the turpentine failed to induce suppuration; he believes that it may arise quite apart from the influence of the organisms of suppuration, that it is not a biological product of the micro-organisms of disease, and also that it has nothing to do with emaciation.
But when the hepatitis is of septic origin, suppuration is likely to occur, the result being an hepatic abscess.
Thus the organisms of suppuration, tubercle, glanders, diphtheria, typhoid fever, cholera, tetanus, and others were identified, and their relationship to the individual diseases established.
A number of interesting experiments, designed to test the relationship between the condition of suppuration and the production of amyloid, have been made of late years.
