BLOOD. 273 



IV. INFLAMMATION OF THE UROPOIETIC VISCERA. 



Nephritis and cystitis. 



Very little has been done in the chemistry of the blood in 

 these diseases. 



Lauer^ found that the blood taken from a man suffering from 

 nephritis, and who speedily fell a victim to the disease, strongly 

 resembled milk. 



Andral and Gavarret2 analysed the blood of a man suffering 

 from inflammation of the bladder, and found it to be composed of 



The increase of the fibrin and the diminution of the corpus- 

 cles show that this blood is similar in its constitution to the 

 blood in other inflammatory diseases. 



The blood in acute rheumatism, erysipelas, tubercular phthisis, 

 puerperal mania, &c., is so strongly impressed with the ordi- 

 nary characters of hyperinosis, that we shall consider it, in re- 

 ference to those diseases, in the present place. 



a. Rheumatismus acutus. 



In acute rheumatism, accompanied by fever, the blood always 

 exhibits, in a more or less marked degree, the characters of 

 hyperinosis. 



The clot is rather small, consistent/ and sometimes covered

* Nasse states that, in inflammatory rheumatism, he has observed a solid clot, 

 although, •when the bufFy coat was very strong, its consistence was less on its lower 

 surface. According to Haller, a thick clot is formed in acute rheumatism. (Stark, 

 AUg. Patholog. p. 950.) Jennings, on the other hand, maintains that the clot under 

 the buffy coat is so loose as to fall to pieces on the slightest touch. (Course of Lectures 

 on the Physiology and Pathologv of the Blood, by Ancell. ' The Lancet,' 1840, p. 841.)
