Abstract

A radiobrominated compound, 4,5,6,7‐tetrachloro‐2β€²,4β€²,5β€²,7′‐tetrabromofluorescein‐^77^Br^4^ was prepared from resorcinol, tetrachlorophthallic anhydride and Na^77^Br by a two‐step synthesis. The precursor was identified by spectrometry. Final purification utilized column chromatography. The product was identified by thin layer chromatography and spectrometry. The yield was 60% of theoretical.

Scanning was used to study liver regeneration in 84 patients operated on for echinococcus liver disease. The conclusion was reached that after an operation on the liver the shape of the liver was the most difficult to restore and easiest was its structure. The degree of restoration of the liver is c
