Dynamic viscoelasticity of bovine vitreous body
Biorheology, 1984The dynamic mechanical property of the vitreous body was studied as functions of frequency and temperature. The data at different temperatures were found to be superposable onto a single set of master relaxation curves. It was found that the shape of the composite master relaxation curves of the vitreous body resembles that of the network polymer ...

Sodium ion distribution in the vitreous body
Magma: Magnetic Resonance Materials in Physics, Biology, and Medicine, 1996We have studied the nuclear magnetic resonance (NMR) relaxation behavior, and thus the dynamic properties, of the sodium ion in the vitreous body at different temperatures. The 23Na NMR spectrum exhibits a resonance, the intensity of which accounts for an ion visibility of 100%. The 23Na longitudinal and transverse relaxation times, at all temperatures

Effect of Osmotic Agents on the Vitreous Body
Archives of Ophthalmology, 1969The weight of the rabbit vitreous body is reduced by average clinical doses of hyperosmolar agents. The weight change is 2.7% with orally administered glycerol, and 3.7% and 3.9% with intravenously administered urea and mannitol respectively. This study substantiates the clinical observation that vitreous volume can be reduced by osmotic therapy.

Flow and diffusion in the vitreous body of the eye
Bulletin of Mathematical Biology, 1975Solution of the equation that describes simulatenous liquid flow and diffusion in a spherical model of the vitreous body of the eye shows that a small dissolved specie can move both anteriorly and posteriorly from a source behind the lens even though there is a slow liquid movement almost entirely in the posterior direction.

Influence of the vitreous body on the lens proteins
Experimental Eye Research, 1963When a dialyzate of the vitreous body is added to whole lens extracts in vitro, a confluence of the α and β fractions is observed in the electrophoretic pattern. This property of the vitreous body increases with age. This effect also depends on the concentration of the α fraction in the lens extract, viz.

Polymeric β-CD and poly{(2-acrylamido-2-methyl-1-propanesulfonic acid sodium salt)-co-[6-(acrylamido)-N-adamantylhexaneamide]} are synthesized to build in situ forming hydrogels based on host/guest interactions, so called physical hydrogels.

We previously proposed a new strategy to replace a vitreous body with a novel foldable capsular vitreous body (FCVB). In this study, the FCVB was designed to mimic natural vitreous morphology, and evaluate its physiological functions compared with ...

Degenerative Conditions of the Vitreous Body
1988Asteroid hyalosis is characterized by the presence of white spherical particles embedded in the vitreous body. About 27% of patients with asteroid hyalosis are diabetic, yet only 5.4% of diabetic patients have asteroid hyalosis. Therefore, the findings of asteroid hyalosis should alert the examiner to the possibility of diabetes in the patient ...

Postmortem Chemistry of the Vitreous Body in Man
Archives of Ophthalmology, 1959While there is information on the chemistry of the vitreous body (VB) in various animals, 1-12,14,15,24-29,31 reports on chemical constituents of the human VB are virtually nonexistent except for a few data on enucleated eyes. 3,16 Since material from human eyes during life is not available, it was thought of interest to investigate the VB of human ...
