Photodegradation of hyaluronic acid and of the vitreous body.
Hyaluronic acid is a mucopolysaccharide. The chemical structure and properties of this group have been extensively studied (Brimacombe and Webber 1964; Schubert and Hamerman 1968; Mathews 1975; Laurent 1987). Hyaluronic acid is present in the connective tissue. It was discovered by Meyer and Palmer (1934) in the vitreous body tissue where its concentration ranges from 140 to 338 mg/dm (Laurent ...
متن کاملProtein Studies on the Human Vitreous Body
INVESTIGATIONS of the vitreous body are beset with numerous technical difficulties. Its large water content and the instability of its structure make it difficult to obtain unchanged vitreous body in large amounts. Through the slit lamp and in fixed histological preparations (Lauber, 1936; Baurmann, 1926; Comberg, 1924; Duke-Elder, 1930), the human vitreous body appears as a structured mass. In...
متن کاملA new biodegradable blends prepared from polylactide and hyaluronic acid
In this article, the biodegradable polylactide/hyaluronic acid (PLA/HA) composites were prepared by a melt blending method. In addition, the acrylic acid grafted polylactide (PLA-g-AA) was studied as an alternative to PLA. The samples were characterized by a fourier transform infrared (FTIR) spectroscopy, a nuclear magnetic resonance (NMR), a differential scanning calorimetry (DSC), an Instron ...
متن کاملStudies on the Structure of the Vitreous Body*
Only a few studies have been reported on the biochemistry of the vitreous body in the developing eye. Bernbridge and Pirie (1) determined the total hexosamine and the total nitrogen content of the filtered vitreous body of rabbits after birth and found that during the first three weeks there was a decrease in both the nitrogen and the hexosamine concentration. Schweer and Siidhof (2) confirmed ...
متن کاملHistochemical localization of hyaluronic acid in vitreous during embryonic development.
PURPOSE To determine the chronology of the appearance and localization of hyaluronic acid (HA) in mouse vitreous during the embryonic and early postnatal stages of development and in human vitreous during early embryonic development. METHODS A histochemical method using the specific affinity for HA of a bovine cartilage proteoglycan was used on mouse eyes at embryonic (11 to 18 days) and earl...
