Abstract: It is an object of this invention to provide an environmental biological allergen measurement method capable of simple and low-cost measurement of the amount of an environmental biological allergen without using anti-allergen antibodies or a special substrate, and to provide a simple biological allergen quantification kit for carrying out the method. The object can be achieved by a biological allergen measurement method characterized in that the amount of an environmental biological allergen is measured by bringing a test substance into contact with a water-soluble gel or aqueous solution containing a substrate of the protease of the environmental biological allergen, and by quantifying the physical change of the water-soluble gel or the aqueous solution caused by the effect of the protease contained in the test substance on the substrate.

Abstract: A vehicle interior-material is provided that efficiently dampens impact forces with ribs protruding into a limited space enclosed by a vehicle panel and a facer, and that reduces the protrusion height of the ribs, thereby curbing the amount that the vehicle interior material bulges into the space of the vehicle interior. The vehicle interior material includes a facer (2) with a substantially C-shaped cross-section covering a panel ridge (7) extending in a longitudinal direction on the vehicle compartment side of a vehicle panel, a space (4) being provided between the panel ridge and the facer; and a plurality of plate-shaped ribs (3) which are arranged independently from one another, bridging side walls of the facer, the ribs protruding from a rear face of the facer (2) opposite the vehicle panel into the space (4) and arranged at substantially right angles with the longitudinal direction of the vehicle panel.
