Increased Ureagenesis and Impaired Nitrogen Use during Infusion of a Synthetic Amino Acid Formula

Abstract
In a controlled trial conducted to assess the biologic value of High Nitrogen Vivonex, we compared this "elemental" diet with predigested protein — Product MJ7041 — and with solid food during eight-day balance periods. Each formula was evaluated in three patients with malabsorption and one without it, by measuring apparent absorption of nitrogen and energy, nitrogen balance, and blood and urinary urea nitrogen.
