 Title    Physical and Chemical Analyses of the Mineral Substance during the Development o f Two Experimental Cutaneous Calcifications in Rats: Topical Calciphylaxis and Topical Calcergy  
 Abstract    In subcutaneous calcinoses induced in rats by topical calciphylaxis and topical calcergy, the ultrastructural aspects related to the evolution o f calcified deposits were previously described. In the present study by m eans o f X-ray diffraction, infrared spectrometry and electron spin resonance, different biophysical analyses are performed on the mineral substance deposited during developm ent o f calciphylaxis and calcergy. A rapid evolution o f the calcium phosphate deposits into hydroxyapatite was noticed along the first 20 days o f the calcinoses; from then, there is no important m odification even at the later stages, and the characteristics o f the mineral substance are mostly sim ilar to that o f bone tissue. The concentration o f trace elem ents such as M g2+ and F e2+, is found higher in cutaneous calcinoses than in bone tissue.
