raffinose/edema

BACKGROUND We have previously shown that the addition of raffinose to low potassium dextran (LPD) preservation solution improves transplanted rat lung function after 24 hours of storage. The mechanisms by which raffinose acts are unclear. The aim of this study was to examine the histologic and

The University of Wisconsin solution differs from other types of solutions used for organ preservation because it contains high-energy phosphate precursors (adenosine and phosphate), impermeants (lactobionate and raffinose), an oncotic agent (pentafraction), and antioxidants (allopurinol and

BACKGROUND Experimentally, the University of Wisconsin solution (UW) has been shown to be superior to the EuroCollins solution (EC) for lung graft preservation. We showed previously that the inclusion of the trisaccharide raffinose as an impermeant in the UW is largely responsible for this

The beneficial effect of UW solution may result from its ability to prevent tissue edema during cold storage. This study was conducted to determine which impermeant was effective in this regard during cold storage of a rat kidney in solution. Functional and morphological studies were made on a rat

It is known that cellular edema and functional impairment develop during anaerobic cold storage of organs. The extent of both is related to the storage time and the composition of the preservation solution used. We studied hypothermia-induced cell swelling and its effect on liver function after cold

Canine pancreas tissue slices were incubated at 5 degrees C for 24 hr in solutions containing different saccharides (raffinose, sucrose, mannitol, or glucose). At the end of incubation tissue water (TW expressed as kg H2O/kg dry wt) was determined as a measure of tissue edema. Tissue edema was
