摘要:
Machine for separating and longitudinally slitting thin sheet, especially double-rolled aluminum sheet or foil, and for winding it onto two winding shafts in abutting strip coils, each winding station including a displaceable cylinder-biased winding carriage with a deflecting roll and a pressure roll defining a terminal sheet run unaffected by the carriage position. Slitting knives arranged on a rotatable swivel shaft in the winding carriage reach into the sheet path in its terminal run, just ahead of the winding point, the slitting knives being retractable into a safe position through rotation of the swivel shaft.
摘要:
Ophthalmic compositions containing biocompatible, bioadhesive polymerizable amphipathic mesophase materials useful for repairing retinal tissue tears or retinal detachments are disclosed. In one embodiment, the polymerizable materials, which comprise substituted fluoroalkyl or perfluoroalkyl monomers having anionic, cationic, and/or nonionic surface active functionality in the unsaturated fluorophobic ends, are polymerized in vivo to provide effective, long-lasting repair of torn, ruptured or detached retinal tissue. Ophthalmic applications of these materials are not limited to retinal repair.
摘要:
Topical ophthalmic compositions of carrageenans which are administrable as a drop but which become more viscous or gel upon instillation in the eye are disclosed. Methods for use of the compositions as topical ophthalmic vehicles for pharmaceutically active agents, and alone as lubricants or tear supplements, are also disclosed.
摘要:
Ophthalmic compositions comprising combinations of gelling polysaccharides and finely-divided drug carrier substrates which become relatively more viscous on contact with the eye are disclosed. These ophthalmic compositions are both comfortable and long-lasting Ophthalmic compositions further comprising a pharmaceutically active drug are also disclosed, as are methods of use.
摘要:
The present invention provides improved dietary supplements and methods for inhibiting the progression of macular degeneration and promoting healthy vision. The dietary supplements of the invention contain cobeadlets comprising vitamin E and carotenoids in the form of Vitamin A, lutein and/or zeaxanthing. The dietary supplements of the invention further contain Vitamin C, copper and zinc and may also contain such ingredients as rosemary, DHA, other vitamins and minerals.
摘要:
The present invention provides improved beadlet formulations useful for inclusion in dietary supplements customized for improving and maintaining ocular nutrition. In particular, the improved beadlets comprise DHA (docosahexaenoic acid); rosemary and/or its components; and excipients.
摘要:
In vivo polymerizable intraocular lens compositions which comprise substituted fluoroalkyl or perfluoroalkyl monomers having anionic, cationic, and/or nonionic surface active functionality in the unsaturated fluorophobic ends. The compositions are preferably cured by UV photoinitiation and are useful in repairing torn or detached retinal tissue or forming intraocular lenses in situ.
摘要:
Fluoroalkyl hydrocarbons as vehicles for pharmaceutical drugs are disclosed. These vehicles are particularly well-suited for delivering drugs which are insoluble in water or chemically unstable in aqueous media. Pharmaceutical solution compositions based on these vehicles have long shelf lives and provide improved drug bioavailability. In addition, the pharmaceutical compositions of the present invention are nonaqueous, and therefore do not require preservatives or tonicity agents. The invention is particularly useful in the field of ophthalmology.
