Thermoreversible Gelation of Aqueous Methylcellulose Solutions
The thermoreversible gelation of methylcellulose in aqueous solution has been studied by static and dynamic light scattering (DLS), small-angle neutron scattering (SANS), and rheology. At 20 °C, dilute solution light scattering establishes the molecular weight, second virial coefficient, radius of gyration, and hydrodynamic radius of the polymer. Semidilute solutions exhibit two relaxation mode...
متن کاملHydroxypropyl methylcellulose in drug delivery
Hydroxy propyl methyl cellulose can be used in the development of different drug delivery technology. Nowadays it is a widely used polymer and different viscosity grade of this polymer is available. The hydrophilic and hydrophobic form (both variants) of this polymer is also available. This study includes a review of this polymer on use in different drug delivery system mosty focusing on more r...

15 صفحه اولPupil size and reactivity following hydroxypropyl methylcellulose and sodium hyaluronate.
AIMS A prospective randomised clinical trial was set up to compare the effect of hydroxypropyl methylcellulose (Ocucoat) and sodium hyaluronate (Healonid) on pupil size and reactivity following their use in cataract surgery. METHODS Pupil measurements were recorded before and 6 weeks after surgery. RESULTS There was no significant difference between the two groups with respect to pupil size...
