Abstract
AIM To estimate the clinical value of 131I-BSA (bovine serum album) solid food in the determination of gastric emptying.
METHODS A standardized meal labeled with dual isotopes (131I-BSA as solid phase and 99mTc-DTPA as liquid phase) was employed to measure gastric emptying (GE) in 35 patients with chronic gastritis and 10 healthy controls. In 2 of them, GE was reexamined using another solid marker 99mTc-SC on a separate day within one week. The correlation coefficient between the repeated solid emptying curves was analysed. The labelled meal were incubated in vitro in human gastric juice (pH 2.0), 1mol/L NaCl (pH 7.0) and 1mol/L HCl (pH 1.0) for 2 hours, and their stability was detected. ......
