Urinary mannitol: lactulose excretion ratios and jejunal mucosal structure.
A dual sugar (mannitol, lactulose) absorption test was evaluated using an iso-osmolar oral dose in two groups of children: a study group of 43 children divided into five subgroups, based on severity of mucosal damage, and a control group of 53 children with histologically normal jejunal biopsy specimens. After an oral dose, the three hour urinary mannitol: lactulose ratios in the control group ...
متن کاملRenal lithium excretion in man.
THOMSEN, KLAUS, AND MOGENS SCHOU. Renal lithium excretion k man. Am. J. Physiol. 215(4): 823-827. 1968.--Renal clearances of creatinine, lithium, sodium, and potassium were determined in six healthy human subjects. Lithium excretion was not significantly affected by water diuresis or the administration of furosemide, bendroflumethiazide, ethacrynic acid, ammonium chloride, spironolactone, or po...
متن کاملRed-cell sodium-lithium countertransport and fractional excretion of lithium in normal and hypertensive humans.
To examine the relations between erythrocyte sodium-lithium countertransport and renal proximal tubular sodium handling, we measured countertransport, and then subjected 30 normal and 32 hypertensive subjects, both white and black, to provocative maneuvers of volume expansion and contraction. The fractional excretions of sodium and lithium were measured simultaneously. In agreement with previou...
متن کاملRenal handling of lithium and the effects of mannitol and arginine vasopressin in man.
1. A study has been undertaken in six healthy male subjects to clarify whether post-proximal segments of the nephron contribute to the renal handling of lithium under conditions of maximal forced osmotic load diuresis and arginine vasopressin-induced antidiuresis. Increments in the fractional clearance of free water, as a measure of effect at the proximal tubule, were positively correlated with...
متن کاملLithium treatment reduces the renal kallikrein excretion rate.
Lithium salts are widely used agents for the prophylactic treatment of affective disorders. Lithium salts may be associated with distal nephron dysfunction. Kallikrein is a protease which is generated by the distal nephron. We used an amidolytic assay of chromatographically purified enzyme to determine the urinary excretion rate of active kallikrein in relation to lithium treatment. All plasma ...
