    摘要: An adjustable shelf system for installation in combination with a non-load bearing wall which does not require penetration of the wall for support is disclosed. The adjustable shelf system is particularly well suited for use in combination with non-load bearing walls of the type supported intermediate a building foundation and an upstanding load bearing frame which includes a top track member having channels for receiving studs and prefabricated wall panels. Shelves are supported on brackets which are attached to laterally spaced, upstanding tubular support legs having a channel formed within one side wall portion. A cushion strip is confined in the channel intermediate the upstanding tubular support legs and the non-load bearing wall thereby preventing abrasive contact of the tubular support legs against the adjacent wall paneling. In a preferred embodiment, an extendable tubular member is coaxially received within the central chamber of each of the tubular support legs and projects above the tubular support legs to an elevation substantially flush with the top side surface of the top track member. Fastener means are provided for mechanicaly interconnecting the extendable tubular member to the top track member for preventing lateral displacement of the tubular support legs relative to the wall paneling.

    摘要: Semisynthetic antibiotics with improved therapeutic properties made from erythromycin are disclosed. 11,12-Cyclic carbamates of erythromycin, its derivatives, and their salts and esters show superior in vitro antimicrobial activity and reduced hepatotoxicity compared to the parent compounds.
