SPS maybe is a potential inhibitor to CaOxa urinary stones by inhibiting the growth of calcium oxalate monohydrate （COM）, preventing the aggregation of COM, and inducing the formation of calcium oxalate dihydrate （COD） crystals.展开更多
The amphiphilic derivatives of 8-hydroquinoline with alkyl chain have been synthesized.These derivatives can form stable monolayer on pure water and an aqueous subphase containing Metal ions.
The ring patterns of calcium oxalate crystals were induced by domains in Langmuir-Blodgett （LB） films of dipalmitoylpho- sphatidylcboline （DPPC）.

The result was explained by the defects at the ring boundaries of liquid condensed （LC） and liquid expanded （LE） phases of LB film. These boundaries could provide less free energy and much more nucleating sites for COM crystals.展开更多
