PTH and chronic kidney disease: For this purpose, this study was designed to map the time-dependent impact of cinacalcet on serum Ca, phosphorus, and PTH in detail in the 5/6 nephrectomized (NX) uremic rats, which develop endothelial dysfunction and left ventricular hypertrophy (Wolf et al. 2000; Gschwend et al. 2002), similar to late-stage CKD patients.
