BIOCOLLOIDS OF URINE IN HEALTH AND IN CALCULOUS DISEASE. III. THE MUCOPROTEIN MATRIX OF URINARY CALCULI 1

Abstract

Over a period of three years 676 renal or ureteral calculi have been decalcified by chelating agents. The matrix has been recovered by ultrafiltration through collodion membranes and sub- jected to analysis by a variety of techniques. The present report is concerned with the microscopic structure and the histochemical properties of the matrix recovered from calcigerous stones.
