INFLAMMATION 61 



idecided activity to reach its .climax within a few days or 

 ^eeks. (c) Subacute ; duration one to two weeks. 



2. Chronic. The inflammatory process is sluggish, pos- 

 sibly extending over years. 



JDepending on the extent, what forms of inflammation are q^ 

 interest ? 



Superficial (external skin, mucous membranes and serous 

 membranes); deep or parenchymatous, subdivided into inter- 

 stitial and parenchymatous ; in the former, the inflammation 

 takes place in the interstitial connective tissue ; in the latter, 

 it involves the parenchyma of the organ, as muscle fibres, 

 glandular cells. The inflammation may be localized or cir- 

 cumscribed and progressive or diffused. 



JN^aTne the more important terminations of inflammation. 



(1) By resolution ; (2) by production ; (3) by necrosis. 

 -Describe the termination by resolution. 



Here the inflammatory exudate is absorbed by the lymph 

 vessels with the assistance of the white blood cells. 



Describe the termination by production. 



Instead of the part returning to its normal condition 

 "without appreciable alteration of its tissues, as is the case in 

 ""resolution," inflammatory new growths follow the inflam- 

 TQatory process, as adhesions, thickening, seen, for instance, 

 in elephantiasis, exostoses, chronic grease (dermatitis ver- 

 Tucosa), etc. 

 JExplain termination by necrosis. 



Gangrene of the inflamed parts is due to severe inters 

 ference with the circulation or septic infection. The dead 

 tissue is separated from the living by suppuration, the line of 

 <iemarcation indicating the place where the separation which
