Compared with brushite stone formers and patients with cystinuria, ductal plugging was more pronounced and the fibrosis was widespread.
No formation of other crystalline phases beside apatite was observed, except for MgCa-HAp, where in addition to the apatite a brushite structure also appeared.
The components are as follows: ammonium hydrogen urate (AMUR), brushite (BRUS), carbonate apatite (CARB), cystine (CYST), struvite (STRU), uric acid (URIC), weddellite (WEDD), and whewellite (WHEW; Table 1).
Researchers found that initial urinary concentrations of calcium oxalate, brushite, and uric acid stones were much greater in patients of both groups, compared to those with no history of stone disease.
Do Cell Culture Solutions Transform Brushite (CaHPO42H2O) to Octacalcium Phosphate (Ca8(HPO4)2(P04)45H2O)?
Depending on laboratory availability, additional parameters, such as potassium, phosphorus, sulphate, ammonia and urea nitrogen, can be requested to allow the calculations of supersaturations for calcium oxalate, uric acid and brushite (calcium phosphate).
Further in vitro and in vivo studies are warranted to investigate whether OCP forming CPCs may have greater osteoconductivity than CPCs that form HA, carbonated HA, Ca-deficient HA, or brushite as the major phase.
