Fig. 1From: The Effect of Seed Crystals of Hydroxyapatite and Brushite on the Crystallization of Calcium Oxalate in Undiluted Human Urine In Vitro: Implications for Urinary Stone PathogenesisParticle size distributions of seeds of hydroxyapatite (HA), brushite (BR), and calcium oxalate (CaOx). The average modal sizes of each seed suspension were alike and were within the Coulter Counter-specified limits (in these experiments, 2–25.4 µm).Back to article page
