  • Patent number: 9433352
    Abstract: An accurate measurement can be made of the light absorbance of deep layer tissue such as in a human body or a fruit. The thickness of fat is computed. A first specific distance and a second specific distance corresponding to the computed fat thickness are computed based a predetermined relationship between the fat thickness, the first specific distance, and measurement sensitivity of a surface layer and measurement sensitivity of a deep layer when light is received at a position the first specific distance away from a light emitting means. A third specific distance and a fourth specific distance are computed corresponding to the computed fat thickness based on a predetermined relationship between the fat thickness, the third specific distance and a measurement sensitivity of an intervening layer and a measurement sensitivity of the deep layer when light is received at a position the third specific distance away from the light emitting means.

  • Publication number: 20040267139
    Abstract: The detecting unit 1 of the instrument of this invention comprises optic fibers 12 and 13 for sensing the inside of the uterus by using near-infrared light of multiple wavelengths, and also comprises a sensor fixture 11 made of a duralumin plate entirely coated with a light-absorbing paint and having a shape with a curvature that allows the fixture to come in close contact with the maternal abdominal wall. This detecting unit 1 is attached to the maternal abdominal wall. The weak light signals obtained as reflections from inside the uterus are converted to electric signals, and these electric signals are arithmetically operated at the measurement control unit 2. In this manner, the inside of the uterus is continuously monitored directly or indirectly by a non-invasive method to detect the intrauterine status of Hb and HbO2.

  • Patent number: 5650394
    Abstract: The present invention provides a method of diagnosing and treating a pregnant female at risk for impending preterm delivery. The method comprises the step of diagnosing imminent preterm delivery by testing with a method that has a sensitivity of at least 80% and a specificity of at least 80%, or by testing for fetal fibronectin in the female's vaginal or cervical secretions. If imminent preterm delivery is indicated by the test, the next step comprises administering to the female a combination of a tocolytic agent, at least one urinastatin-like compound, and at least one antibiotic. Also provided is a pharmaceutical composition of MGMTSRYFYNGTSMA (SEQ ID NO:1), RAFIQLWAFDAVKGK (SEQ ID NO:2) and an antibiotic.

  • Patent number: 5290679
    Abstract: Even when the specimen contains human granulocyte elastase in the form of a mixture of free elastase with an elastase-inhibitor complex or complexes, the present invention enables the total quantity of elastase in that specimen to be precisely detected. The inhibitor is added to free elastase to convert it into an elastase-inhibitor complex, whereby the quantity of elastase can be measured by immunoassay as the total amount including the previously existing elastase-inhibitor complex. It is possible to precisely measure the total amount of elastase in mucus collected from the cervical canal of a pregnant woman, sputum or a rinsed solution of bronchovesicular lavage in which free elastase is mixed with an elastase-inhibitor complex.
