Fibrin (fi / -brin) [fibra, a fiber]. A native albumin or 

 proteid, a substance that, becoming solid in shed 

 blood, plasma, and lymph, causes coagulation of these 

 fluids. It then exists in the shape of innumerable, 

 excessively delicate, closely packed, microscopic, 

 doubly refractive fibrils, entangling the blood-corpus- 

 cles, as in a spider's web, and with them forming the 

 blood-clot or placenta sanguinis. Fibrin forms about 

 0. 2 per cent, of the blood and is insoluble in water 

 and ether. It is changed into syntonin by dilute 

 hydrochloric acid. F. -ferment, a ferment obtainable 

 from blood-serum after clotting has occurred. It 

 does not exist in the living, circulating blood. Its 

 activity is destroyed by heating to 70 F.

 obtained from blood-plasma, serous transudations, etc.

 in the formation of fibrin (the other being Paraglobu- 

 lin), which occurs dissolved in the plasma, aided by a 

 fibrin-ferment.

 to produce]. Of the nature of fibrinogen. 



Fibrinogenous (fi-brin-ofi -en-us) [fibra, a fiber ;

 of or containing fibrin. 



Fibrinuria (fi-brin-u' '-re-ah) [fibra, a fiber ; ovpov, 

 urine]. The presence of fibrin in the urine to an 

 extent that causes its coagulation after the liquid 

 has been voided. It usually occurs in the course of 

 villous cancers of the bladder, or after the use of 

 cantharides.

 ing fibro-cartilage.

 constituent of the cocoons of insects and spider-web. 

 See also Fibrorin. 



Fibro-lipoma ( fi-bro-lip-o 1 '-mah) [fibra, fil>er ; 



fat; bfia, tumor: //. , Fibro- lipomata]. A neoplasm 

 constituted of both fibrous and fatty elements.

 //. , Fibromata]. I. Any fibrous-tissue tumor; it is 

 called also inoma. 2. See Afolluscum fibrosum. F., 

 Concentric, a soft, red, vascular form of uterine fibro-
