Assessment of The Potential Role of Parsley (Petroselinum Crispum) Leaves Extract in Ameliorating Cyclosporin A- Induced Nephrotoxicity in Rats

In this study, a potentiometric titration method by Calvin-Bjerrum and Irwing-Rosotti was used to investigate binarycomplexes of ibandronate sodium, a nitrogen-containing bisphosphonate, with Ca(II), Mg(II) and Sr(II). Dissociationconstants (pKa) of ibandronate sodium were measured and the stability constants of the complexes formed in aqueoussolutions at 22 oC (I = 0.11 M NaClO4) were determined. The stoichiometry of ibandronate sodium/metal complexes wasfound as 1/1 for each metal ion.
