  • Title: Membrane interactions with calcium oxalate crystals: variation in hemolytic potentials with crystal morphology.
    Author: Wiessner JH, Mandel GS, Mandel NS.
    Journal: J Urol; 1986 Apr; 135(4):835-9. PubMed ID: 3959216.
    Abstract:
    Crystal-induced membranolysis of human red blood cells has been quantitated for calcium oxalate monohydrate and calcium oxalate dihydrate crystals. Calcium oxalate monohydrate crystals are significantly more membranolytic than calcium oxalate dihydrate crystals at constant surface area. If the crystal morphology of calcium oxalate monohydrate is altered by grinding, the lytic potential at constant surface area is markedly reduced. However, altered calcium oxalate dihydrate crystals are as lytic as natural calcium oxalate dihydrate crystals at constant surface area. Differences in the calcium oxalate monohydrate and dihydrate crystal structures, specifically the structural characteristics of the disordered water channel in calcium oxalate dihydrate, can explain these different membranolytic characteristics.
