The present invention relates to a compound which is an antagonist of CXCR3 or an inhibitor of the CXCR3 receptor expression for the treatment of glaucoma. The extractor region is reversed biased to remove minority carriers from the body region of partially depleted memory cells. The hook member includes an operation portion and at least one hook portion. A high-pressure range tonometer instrument is also provided. Firstly a layer of powder or granular material with a uniform weight per unit area is formed on a substrate, and then application, dispensing, or deposition is performed by sucking the powder or granular material on the substrate and ejecting it to the object. Before entering the engine block, the compressed air from the air pump passes through an air filter that cools the air.
