[Comparative studies of various methods of measuring bile acid secretion using 75Se-labelled homotaurocholic acid
Abstract:
The simple determination of whole-body retention of the bile acid analogue 75Se-HCAT provides results which are in agreement with those of the established but more difficult measurement of 24-14C-TCA excretion in the feces. Determining whole-body retention of 75Se-HCAT is not only practicable with a whole-body counter but also, with precision, with the more widely used gamma camera. Therefore, the bile acid retention test may be employed wherever there is a gamma camera available.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
