Title: Modified.alpha.2-macroglobulins and their use as scavengers for cytokines and growth factors
Inventor: HAYES ANTHONY
IPC: A61K38/17
Filed: 1990-10-18
Abstract: The invention relates to a method for preventing the interaction of growth factors or cytokines with their specific cell receptors in mammals. The method comprises administering to the mammal a therapeutic amount of a chemically modified .alpha.2-macroglobulin having the ability to form a .alpha.2-macroglobulin-growth factor or -cytokine complex with a given growth factor or cytokine.  The complex preferentially undergoes recepto-medicated modification, preferably endocytosis by .alpha.2-macroglobulin receptors, thereby reducing the availability of the active growth factor or cytokine to its specific cell surface receptor.

Filed: 1992-09-17
Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to an improved toilet-type flush valve in which a flush valve body having an inlet and an outlet defines a flow path.  There is a piston movable in the valve body to control water flow along the flow path and there are means within the valve body which cooperate with the piston to define a control chamber.  There is a metering orifice opening into the control chamber, with the metering orifice being upstream of any flow path restriction, with the result that the metering orifice is always at inlet pressure.  There is a vent passage connecting the control chamber and the valve body outlet and an externally operable plunger, which may be caused to move by a manual handle or an electric operator.  Movement of the plunger opens the vent passage, permitting the piston to vent the control chamber, which opens the flow path between the valve inlet and valve outlet.

Patent CA-2084159-A1 (CA)
Inventor: CANARY STEPHEN A
IPC: B44C5/04
Filed: 1992-11-30
Abstract: ABSTRACT   Certain water insoluble basic salts and, more particularly, alkaline earth metal hydroxides are introduced to the papermaking furnish for a decor sheet. The decor sheet which is coloured by a sulphur dye and contains the water insoluble basic salts exhibits good postformability. The water insoluble basic salts prevent the sulphur dyes from catalyzing curing of the resin and thus yields a decor sheet with good postformability. A combination of water soluble salts is added to the furnish which interacts by ion exchange to precipitate a water insoluble basic salt in the furnish. For example, an alkaline earth metal salt such as magnesium sulphate is reacted with sodium hydroxide to precipitate magnesium hydroxide in the furnish.

Abstract: SURGICAL PURSE STRING         SUTURING INSTRUMENT AND METHOD     ABSTRACT OF THE DISCLOSURE     A purse string suturing instrument is provided for quickly and effectively forming a purse string suture in tubular tissue through relatively small cannulas placed in the body.  The instrument includes a pair of elongated jaws, each having a row of spaced-apart uniform-size teeth.  The jaws are hinged together at one end to clamp the tubular tissue therebetween.  The two rows of teeth are offset with respect to each other so that they mesh when the jaws are closed.  The jaws are inserted through a cannula and positioned to close around the tissue to be sutured.  The rows of teeth then bend the tissue between them into a wavelike configuration.  A pair of needles, the ends of each being connected to a single length of suture, is then inserted through passageways provided through the teeth.  An encircling series of stitches are thus formed in the wall of the tubular tissue to create a purse string suture.  The needles and the suturing instrument are then withdrawn through the cannula.  The tubular tissue can be snugly fitted over an anastomosis ring or the like by drawing and tying the purse string suture.
