to investigate the mechanisms of abnormal calcium metabolism , such as hypocalcemia , decreased intestinal calcium absorption and hypercalciuria in spontaneously hypertensive rats ( shr ) , we have measured the plasma concentration of calcitriol and its synthesis in 5- , 8- , 12- , 16- , and 20-week-old normotensive wistar kyoto rats ( wky ) and shr .
