Background/Aims : We investigated whether the presence of bile changes the
cholesterol dissolving capacity of methyl-tert-butyl ether (MTBE) or ethyl propionate
(EP) and dimethylsulphoxide (DMSO) enhances the cholesterol dissolving capacity of
MTBE or EP solvent when cholesterol gallstones were dissolved with bile.
Methods : We mixed MTBE (or EP) with water or bile. Then, pure choesterol was
dissolved in this solvent and its concentration was measured by cholesterol kit.
MTBE/DMSO and EP/DMSO mixtures were prepared and added to different amount of
bile and cholesterol. The cholesterol concentration of these mixtures were determined by
cholesterol kit. The eight weight-matched cholesterol gallstones were selected and
divided into two groups. One group was for MTBE/bile and MTBE/bile/DMSO mixtures
and another group was for Ep/bile and EP/bile/DMSO mixtures. Each stones were
placed in test tube with each solvents. Creating turbulence manually 4-6 cycle a minute,
the solvent and bile were exchanged every 15 minutes and stones were dried and
weighed until complete dissolution. We measured complete dissolution time or weight
percent of remained stone 300 minutes later.
Results : The presence of bile or water decreased cholesterol dissolution capacity of
MTBE and EP by 33-42% Addition of DMSO to MTBE/bile enhanced cholesterol
dissolving capacity and shortened cholesterol stone dissolution time by 43%. Addition of
DMSO to Ep/bile increased cholesterol stone dissolving capacity by 15.3%.
Conclusions : MTBE/DMSO is more potent and useful dissolution agent for cholesterol
gallstone than MTBE alone under bile milieu, giving a reduction in dissolution time.
