[Radionuclide study of absorption in the intestines in acute poisonings]
Abstract:
A study was made of the intestinal absorption of 131I-oleic acid and human serum 131I-albumin in patients with acute exogenous intoxications and endogenous intoxications caused by acute intestinal ileus using the method of external radiometry of the abdominal parts. The utmost disorders of absorption were noted in patients with an average and grave degree of exogenous intoxication as well as in patients with complete occlusion ileus. Absorptive intestinal capacity in most of the patients improved as a result of therapeutic measures. A rapid method for the evaluation of absorption power was developed and compared with the method of external radiometry of the abdominal parts. An equation of regression was derived making it possible to determine values of the parameter of a period of drug semiabsorption using the rapid method values.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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 vitro
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...
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,...
