INFLAMMATION. 141 



examj)les are chronic etfusion into serous cavities, the i^leura 

 joints, or tunica vaginalis (hydrocele). 



Fibrinous Inflammation. — In this form the exudation is still 

 more richly albuminous and contains more leucocytes; it conse- 

 quently has a much greater tendency to coagulate, and lymph 

 forms on the inflamed surface or in the substance of the inflamed 

 tissue. The most typical examples are found on serous mem- 

 branes. 



Productive Inflammation. — This is the case when the in- 

 flammatory process ends in the formation of new tissue. In this 

 case any fiber jiresent disappears before the leucocytes, which 

 crowd into the lymph and convert it into a tissue of closely- 

 packed leucocytes in a scanty homogeneous matrix. To supply 

 this with nourishment, vascular loops spring from the capillaries 

 of the inflamed tissue and penetrate into the lymph in all direc- 

 tions; this is granulation tissue. 



Ulcerative Inflammation. — AVe have seen that suppuration 

 in the substance of tissues produces molecular disintegration of 

 them; as a rule, indistinct slough is found in pus. The same 

 molecular distinction, eating away the tissues on a free surface, 

 constitutes ulceration. 



Hemorrhagic Inflammation. — This form of inflammation is 

 characterized by an exudation in which red corpuscles are in 

 great excess. The results of inflammation are resolution, adhe- 

 sion, effusion, suppuration, ulceration, and mortification, or gan- 

 grene. Eesolution is the most frequent and most favorable ter- 

 mination of inflammation. It consists in the cessation of the 

 process and the restoration of the part to health. The corpuscles 

 of the stagnant blood move off, one after another, till a slow 

 stream is re-established through the inflamed area; the flow 

 quickens as resistance lessens and as the vessels contract, owing 

 to gradual recovery of their muscular coats; exudation, first of 

 corpuscles, then of fluid, ceases, and the circulation again be- 

 comes normal. "Whatever favors the re-establishment of normal 

 circulation in the inflamed area will favor resolution. This may
