to determine the contribution of the juxtamedullary loop of henle to magnesium reabsorption during magnesium deficiency , we performed two-phase micropuncture studies of end-descending limbs in a group of magnesium-deficient rats ( n = 7 ) and in a pair-fed control group ( n = 8 ) given mgcl2 in their drinking water .
