[Evaluation of reserve potentials of the heart in diseases of the abdominal aorta in middle aged and elderly patients].

By the method of radionuclide ventriculography on the nuclear stethoscope, 106 patients at the age of 60-84 years with occlusive lesions (64) and abdominal aortic aneurysm (42) were examined. After preoperative therapy, 48 patients underwent resection of the abdominal aortic aneurysm with grafting, 41--aortofemoral shunting. Three (7.

[Analysis of 99mTc-HIDA kinetics using an adaptive model].

The paper is concerned with the results of assaying hepatocyte function on the basis of an adaptive pharmacokinetic model worked out by the authors. Hepatoscintigraphy with 99mTc-HIDA was used in 3 phases: the vascular phase of RP transport (the 1st min of investigation, scintigrams with a 2 s interval), the parenchymatous phase (with a 20 s interval in subsequent 10 min), the biliary phase (with a 3 min interval). The hepatocytic phase of 99mTc-HIDA transport was evaluated on the basis of the adaptive 5-compartmental model calculating the value of transport constants.
