Substances for the complex modus lubrication in artificial joints
Štol, Miroslav ; Musil, Jan ; Pražák, Josef
We have been studying some possibilities to fulfil the lubricationn demands in artificial joints. The interactions of gamma-globulin (GG) or polyvinylpyrrolidone (PVP) with sodium salt of carboxymethyl cellulose (NACMC) were followed by te rheological
Supermolecular arrangement in the development of pseudosynovial fluids
Štol, Miroslav ; Musil, Jan ; Pražák, Josef
Attention has been paid to sodium salt of carboxymethyl cellulose as a hyaluronic acid substitude. The latter substance has been modified by addition of some metalic ions. Measurements of dynamic viscosity of the NaCMC solutions revealed that bivalent metallic ions do not adequately crosslink polymer chains in an intermolecular fashion. On the other hand, some multivalent metallic ions (Mn or Ce) were active in crosslinking the polymer chains, thus forming their supermolecular arrangement.
Artificial joint lubrication
Pražák, Josef ; Štol, Miroslav ; Musil, Jan
