Twenty-one anicteric patients with a t-tube in situ were studied between the ninth and 11th postoperative days. Eleven patients were given an intravenous infusion of the biliary contrast agent ioglycamide (Biligram), while the other 10 acted as controls. Bile flow was recorded and the biliary concentrations of ioglycamide, bile salt, phospholipid, and cholesterol estimated in the two groups. The biliary excretion of ioglycamide was associated with a significant choleresis which was probably due to the obligatory coupling of the osmotically active contrast agent molecules with water. Biliary ioglycamide excretion did not significantly alter bile salt secretion rates. In contrast, the biliary secretion of both phospholipid and cholesterol was significantly lowered (P less than 0.001). Unlike chenodeoxycholic acid, ioglycamide significantly reduced bile acid independent cholesterol secretion (P less than 0.01), although secretion rate in terms of mumol of bile acid was essentially unchanged.

Patients with the clinical diagnosis of acute cholecystitis were studied with intravenous cholecystography and cholescintigraphy. The two examinations alternated in a random order. The final diagnosis was ascertained by surgery in most patients.

The quality of 96 infusion cholegraphies with isotonic Ioglycamide-85 solution and of 2,080 infusion cholegraphies with hypotonic adipiodone-50 gave equal images in 97% of the cases. Ioglycamide-85 caused side-effects in 15.6%, Adipiodone only in 1.

This study compares the effects of the low osmolality agents with those of the conventional agents by in vitro studies of platelet function, fibrin formation, and fibrinolytic activation. In various degrees, all the contrast agents studied inhibit platelet aggregation and fibrin formation but show virtually no direct activation of fibrinolysis.

Changes in serum T3, rT3 and T4 demonstrated different trends for each iodinated compound, probably depending on the regulatory thyroid mechanisms, and CM pharmacokinetics. Plasma profiles of free fractions (FT3, FT4) slightly reflected consensual changes with circulating iodothyronines, at various time periods of study, demonstrating high correlation indexes with total fractions.
