Detection of sulfur-containing compounds in control and cadmium-exposed rat organs by high-performance liquid chromatography--vacuum-ultraviolet inductively coupled plasma-atomic emission spectrometry (HPLC-ICP).
Sulfur-containing compounds in biological samples were separated by high-performance gel permeation chromatography and detected with a vacuum-ultraviolet inductively coupled plasma-atomic emission spectrometer. Distribution profiles of sulfur in the supernatants of liver, kidney, spleen, lung, and pancreas of control and cadmium-exposed rats were determined along with cadmium, copper, iron, phosphorus, and zinc profiles. Changes in sulfur distribution were induced by cadmium exposure not only in the metallothionein fraction, but also in the high-molecular-weight protein fraction, indicating the effect of cadmium exposure on diverse endogenous sulfur-containing compounds. Glutathione and taurine also were detected simultaneously as distinct peaks.
