Abstract: A gazebo with a two-dimensional cover and a rod assembly, which is connected to the cover and holds the cover in a three-dimensional shape. The rod assembly is formed of a main rod assembly and a secondary rod assembly, wherein the main rod assembly has one or more resilient rods, which connect end portions of two opposing gussets of the cover. The secondary rod assembly has one or more resilient rods to connect in each case center regions of the edge between two adjacent gussets of the cover with each other. At least one tensioning element to increase at least the spacing between the ends of a rod of the rod assembly to hold the gazebo in its three-dimensional shape. The gazebo has no center rod which supports the gazebo from the ground and which in particular provides no variation in spacing.

Abstract: Disclosed are solutions useful in surgery comprising a viscous or viscoelastic substance in an aqueous vehicle which is characterized as physiologically compatible; also disclosed are methods of using such solutions, implanting such viscous or viscoelastic substances, while minimizing the traumatic effect of surgery at the cellular level.

Abstract: Irrigating solutions with thiol or disulfide containing compounds in physiologically acceptable salt solutions are described. The irrigating solutions are useful during surgery, particularly ophthalmic, neural, cardiovascular or otic surgery, to stabilize the affected tissue. Methods for their preparation and use are described.

Abstract: Ophthalmic solution suitable as an artificial tear material of low viscosity containing a polysaccharide and benzalkonium chloride.
