Abstract: A novel acute care cerebral support system and method for treating severly ischemic brains is disclosed wherein an oxygenated nutrient emulsion is circulated through at least a portion of the ventriculo-subarachnoid spaces. The nutrient emulsion contains an oxygenatable non-aqueous component, an aqueous nutrient component, an emulsification component, and other components which render physiologic acceptability to the nutrient emulsion. The disclosed system and method have been shown to effectively exchange oxygen, carbon dioxide, glucose, and other metabolites in severely stroked brains. Significant restoration of oxidative metabolism and electrographic activity result from the disclosed treatment. Methods for producing the nutrient emulsion and a system for delivering that emulsion to the cerebrospinal pathway are also disclosed. Additionally, novel diagnostic methods for diagnosing the physiologic state of hypoxic-ischemic and other diseased neurologic tissue during treatment are provided.

Abstract: Process for separating a pre-polymerized composite dental filling, such as an inlay, from the hard substance of the tooth using a separating substance consisting of a sol formed from a substance swollen and dissolved in alcohol and forming an organic or inorganic gel. The separating substance is applied as a separating layer to the cavity prior to introducing the composite into the cavity and this facilitates the removal of the composite after hardening in the cavity. The separating layer is removed from the cavity, and the inlay is then cemented into the cavity after being tempered.

Abstract: A glass sheet is provided with a coating which will automatically reflect infrared radiation if the ambient temperature is above about 45.degree. F.-60.degree. F. and will transmit infrared radiation if it is below about 45.degree. F.-60.degree. F. Such a coating is placed on the exterior surface of the glass. Additionally, the interior of the glass may be provided with a controllable infrared transmittable or reflective layer of material which is activated by means of an electric current transmitted therethrough and which will reflect infrared energy if so energized, but otherwise will transmit such infrared energy. This layer of material is preferably placed on the interior of the glass surface and activated during the nighttime period so that infrared energy is not transmitted outwardly. Alternatively, the controllable infrared transmittable or reflective layer of material may be positioned both on the exterior and interior of the glass surface.

Abstract: A method and system are disclosed for externally treating human blood, with the objective of reducing the functioning lymphocyte population in the blood system of a human subject. According to the method, blood is withdrawn from the subject and passed through an ultraviolet radiation field in the presence of a dissolved photoactive agent capable of forming photo-adducts with lymphocytic-DNA, mobile hormonal hormonal receptors or antigen sites to thereby effect covalent bonding between the photoactive agent and the same, thereby inhibiting the metabolic processes of the lymphocytes or complexing them; and thereupon returning the irradiated blood to the subject. The withdrawn blood may be formed into an extracorporeal stream and flowed through a treatment station whereat the irradiation is effected, as for example by exposure to UV radiation; and such flow process may be conducted on a continuous basis.

Abstract: Ski upper- and lower-surface constituting materials are set in position in a mold provided with a space appropriate for the dimensional distribution of the padding for the ski. The ski upper-surface constituting material is arranged so that a resin sheet of ABS resin, etc. constitutes the outer surface of ski. The inner upper surface of the upper mold piece is formed in a curved surface having, for example, grooves. A foamy resin is injected to fill the space between the ski upper and lower constituting materials. The foaming pressure raised by the foamy resin will press the resin sheet against the inner upper surface of the upper mold piece with resulting deformation of the resin sheet. Thus one may obtain a ski which is provided on its upper surface with projections.
