The invention disclosed comprises a method for administering the antidiabetic drug glipizide to a patient in need of glipizide in need of antidiabetic therapy.

A small diameter flexible electrode designed for subcutaneous in vivo amperometric monitoring of glucoses is described. The electrode is designed to allow "one-point" in vivo calibration, i.e., to have zero output current at zero glucose concentration, even in the presence of other electroreactive species of serum or blood. The electrode is preferably three or four-layered, with the layers serially deposited within a recess upon the tip of a polyamide insulated gold wire. A first glucose concent...

The sensitivity of enzyme-based polarographic electrodes to oxygen concentration can be significantly reduced or eliminated by providing an oxygen-reservoir in intimate contact with the oxidative enzyme. This is achieved by making a stabilized emulsion between the enzyme and a compound in which oxygen is extremely soluble. An aqueous glucose oxidase solution is emulsified with a perfluorocarbon liquid, and the resulting emulsion is stabilized by chemically crosslinking the mixture to form a gel....

A luminescent in vivo glucose measurement method and apparatus is provided. The luminescent in vivo glucose measurement method includes the steps of illuminating displaced luminescent molecules with illuminating light, the displaced luminescent molecules and associated captive glucose analogue molecules being contained within an implanted luminescent in vivo measurement apparatus implanted within the interstitial fluid of the subject, and measuring an emitted light, the emitted light being emitt...

A neutral glucose-containing preparation with excellent stability and a near physiological pH, as a transfusion preparation with minimal glucose degradation by-products and a greatly reduced formic acid content; specifically, a glucose-containing preparation comprising separately housed first and second solutions, the first and second solutions satisfying the following conditions: (a) the first solution contains 2-50% glucose, and its pH is adjusted to 3-5 with an organic acid buffer solution; (...

Methods are provided for glucose detection and quantification in urine. The methods include selecting a test device comprising a matrix impregnated with a chromogenic indicator mixture, locating the test device to promote incidental contact of same with animal urine, reading a developed indicator color after the device has been wetted with urine, and determining the animal's urine glucose concentration.

This invention relates to an isolated nucleic acid fragment encoding a hemicellulose biosynthesis protein. The invention also relates to the construction of a chimeric gene encoding all or a portion of the hemicellulose biosynthesis protein, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the hemicellulose biosynthesis protein in a transformed host cell.

A biosensor that enables rapid and simple quantitation of a substrate with high accuracy and demonstrates an excellent preservation characteristic by best retaining enzyme activity is disclosed. The biosensor comprises an electrically insulating base plate, an electrode system including at least a working electrode and a counter electrode formed on the base plate, and a reaction layer containing at least an enzyme and a sugar. The reaction layer may be formed on the electrode system. The enzyme ...

A membrane and the method of making the same is disclosed for use with glucose analyzers to detect the level of glucose in liquid mediums such as whole blood. The membrane comprises a thin base wafer of a hydrophobic fluorocarbon material such as polytetrafluoroethylene (TEFLON). The wafer is initially etched by removing surface fluorides to produce a hydrophilic surface and is then contacted with a mixed reagent formed by combining in a volume ratio of about 1:1:1 about 4% paraformaldehyde in w...

An esterified propoxylated methyl glucoside composition is prepared by reacting a propoxylated methyl glucoside with a fatty acid at an elevated temperature in the presence of an acid catalyst. The esterified propoxylated methyl glucoside compositions find use as skin moisturizers and emollients which are especially suitable in skin care formulations.
