Increased activity of ionised calcium in gall bladder bile in gall stone disease.

Increased activity of ionised calcium in gall bladder bile in gall stone disease.

The actual activity of ionised calcium (Ca2+) in gall bladder bile determined with an ion-selective electrode was significantly higher in patients with gall stone disease (n = 15) than in patients without gall stones (n = 10) (0.43 mmol/kg v 0.31 mmol/kg; p < 0.05). No change in the Ca2+ activity in any of the gall bladder bile samples was observed during equilibration with CO2. During titratio...

Nucleation time of gall bladder bile in gall stone patients: influence of bile acid treatment.

The time required for precipitation of cholesterol crystals (nucleation time, NT) was determined and related to the cholesterol saturation in gall bladder bile of gall stone free subjects (n = 11), patients with pigment stones (n = 3), and patients with cholesterol gall stones (n = 30) undergoing cholecystectomy. Seven of the gall stone patients had been treated with chenodeoxycholic acid (CDCA...

Gall stone disease without gall stones--bile acid and bile lipid metabolism after complete gall stone dissolution.

Although bile acid and bile lipid metabolism have been studied in established cholelithiasis, little is known about them in patients destined to develop gall stones, but in whom the stones have not yet appeared (prestone gall stone disease). After confirmed complete gall stone dissolution and withdrawal of treatment, gall stones recur frequently. Before the stones reappear, these patients have ...

Interactions between gall bladder bile and mucosa; relevance to gall stone formation.

Mucin in gall bladder bile of gall stone patients: influence of treatment with chenodeoxycholic acid and ursodeoxycholic acid.

The concentration of hexosamine, a marker for mucin, was determined and related to the degree of cholesterol saturation and to the occurrence of cholesterol crystals in gall bladder bile of gall stone patients (n = 40) and gall stone free subjects (n = 25). Ten of the gall stone patients had been treated with chenodeoxycholic acid (CDCA) and eight with ursodeoxycholic acid (UDCA) three to four ...
