摘要：
The effect of monocarboxylic acetic acid (HAc), dicarboxylic tartaric acid (H,tart), and tricarboxylic citric acid (H(3)cit) on growth and aggregation of calcium oxalate (CaOxa) crystals was investigated in gel at different temperature. Calcium oxalate dihydrate (COD) crystals were induced under the conditions of low temperature and in the presence of di- and tricarboxylic acids. The calcium oxalate monohydrate (COM) crystals were more rounded and blunt in the presence of H(3)cit and H(2)tart. If more COD or more COM crystals with round tips and edges can be induced, CaOxa stones can be inhibited. (c) 2005 Elsevier B.V. All rights reserved.
