Amyloid or Amylaceous Bodies.. These are small circular 

 or oval bodies which give the starch reaction with an iodine solu- 

 tion. Just what their significance is, is not known. Virchow first 

 described them. They have been found in various tissues and 

 excretions, including the urine normal as well as pathological. 

 In diseases of the kidneys, Veitz and Wederhake found that these 

 amyloids afford us important indications ; but that in affections 

 of the bladder they are present in increased quantity. Weder- 

 hake therefore suggests that the amyloid bodies have a certain 

 value in differential diagnosis. The absence of the bodies in 

 pathological urine is against catarrhal disease of the bladder; 

 whilst their presence, especially if numerous, in urine which ap- 

 pears to contain renal elements only, indicates that the bladder 

 is also affected. (Dixon Mann). 



The urinary sediment stained with a dilute Lugol's solution 

 show these bodies, when present, varying in color from a blue to 

 a deep blue black color.
