摘要：
The viscosity of hyaluronic acid solutions kept at different pH values was found to decrease in the following order of pH: 6.5 > 3.5 > 4.3, although acid hydrolysis occurred at a higher rate in the most acidic solution. The poorest stability of the solutions with pH 4.3 was attributed to the compaction of the macromolecules as a result of charge density redistribution along the polyacid chains.
