The renal tubular handling of aldosterone and its acid-labile conjugate.
Stop-flow studies using infusions of aldosterone-(3)H or its (3)H acid-labile conjugate were done on five rhesus monkeys. The aldosterone-(3)H urine-to-plasma (U/P) ratio decreased in the same distal urine samples as sodium. The (3)H acid-labile conjugate U/P-to-inulin U/P ratio increased in the more proximal samples either with conjugate formed endogenously during aldosterone-(3)H infusions or with labeled conjugate infused alone. Aldosterone reabsorption occurred at a distal site in the renal tubule, and secretion of its acid-labile conjugate occurred at a proximal site.

Uremia with low serum creatinine-an entity produced by marked creatinine secretion.
Two patients are presented who were uremic requiring dialysis despite steady state serum creatinine levels (Cr) of 4.0 and 4.4 mg percent. Their blood urea nitrogen/creatinine (BUN/Cr) ratios of 54 and 44 were shown to be due to excessive creatinine secretion and urea reabsorption. Evaluation of serum creatinine alone may occasionally give misleading information regarding the level of renal function. If clinical evidence of uremia is present while serum creatinine value is relatively low, measurement of glomerular filtration rate (GFR) by Na-iothalamate 125I (OIT) or inulin is essential.

Community youth development: learning the new story.
Community youth development is a challenging approach to youth work that focuses on the incorporation of new values at the practice, management, and community levels. This article explores the implementation of a community youth development approach within the context of learning organization theory, and describes the experiences of three youth-focused agencies making the transition to a community youth development approach.
