Radioisotope-dilution technique for determining endogenous manganese in feces of the growing rat

Biological Trace Element Research, 1986
A conventional balance study with growing rats was conducted to evaluate experimental conditions for determining endogenous fecal manganese (Mn) excretion and, hence, true Mn absorption by the isotope-dilution technique. Thirty-four rats, with a mean initial live weight of 60 g, allotted to three groups of 8 animals and one group of 10 animals, were ...

Radioisotope Dilution Technique for Determination of Zinc Absorption <i>in vivo</i>

Annals of Nutrition and Metabolism, 1976
A radioisotope dilution technique was adapted for determination of the absorbability of dietary zinc. In 16 growing rats given a casein diet with 12.8 mg Zn/kg dry matter, a mean apparent Zn digestibility of 72.4 % was observed in a 6-day balance period 9 days after an intramuscular injection of ⁶⁵Zn-ZnCl₂.

Blood volume analysis by radioisotopic dilution techniques: State of the art

Applied Radiation and Isotopes, 2015
In the last years, there has been a growing recognition of the importance of blood volume abnormalities in the pathophysiology of several conditions and, consequently, a growing interest of accurate and rapid volume status assessment. Accordingly, there has been a surge of interest in blood volume analysis by radioisotopic dilution technique.

Determination of silver in rocks by a stoichiometric radioreagent radioisotope dilution technique

Analytica Chimica Acta, 1975
Abstract A rapid procedure for the routine determination of nanogram amounts of silver in rocks is described. After dissolution of the sample with a hydrofluoric-nitric-perchloric acid mixture in the presence of 110Ag tracer, the silver is separated by extraction as the dithizonate into xylene and back-extracted into dilute hydrochloric acid.

Radioisotope dilution technique for determination of zinc absorption in vivo.

Nutrition and metabolism, 1977
A radioisotope dilution technique was adapted for determination of the absorbability of dietary zinc. In 16 growing rats given a casein diet with 12.8 mg Zn/kg dry matter, a mean apparent Zn digestibility of 72.4% was observed in a 6-day balance period 9 days after an intramuscular injection of 65Zn-ZnCl2.
