Abstract:
Four patient groups (n = 28 patients) received in a randomised clinical trial a single intravenous infusion of 500 ml of 10% dextran 40, 3.5% oxypolygelatine, 6% hydroxyethyl starch 200/0.5 or saline solution, respectively. The haemorheological parameters haematocrit, plasma viscosity and erythrocyte aggregation were followed up during 48 hours. In our study oxypolygelatine showed better rheological results than HAES 200/0.5. Dextran 40 especially increased the plasma viscosity and erythrocyte aggregation, so that we cannot recommend this plasma substituent for hypervolemic haemodilution.

The colligative properties of a solution depend only on the number, not on the identity, of solute species dissolved. The concentration terms in the equations for various colligative properties (freezing point depression, boiling point elevation, osmotic pressure) pertain to all solute species present in the solution. Nonelectrolytes dissolve physically without dissociation or any other accompanying process. Each molecule that dissolves yields one...

Electrochemistry is a branch of chemistry that describes and measures the relationship between electrical energy and a chemical change. Electrochemical reactions involve the movement of electrons from one species to another. If the reaction is spontaneous, it can result in a generated current. If the reaction is not spontaneous, it can be driven by the application of current.
In electrochemistry, the key reaction is the oxidation-reduction reaction, called a redox reaction. The...
