    摘要: Ophthalmic pharmaceutical compositions useful in controlling elevated intraocular pressure associated with glaucoma and ocular hypertension are described. The compositions comprise a combination of a beta-blocker and a carbonic anhydrase inhibitor to reduce the production of aqueous humor, preferably formulated as a suspension having a pH between about 6.8 and about 7.8. These compositions may additionally contain a mucomimetic anionic polymer and/or a finely-divided drug carrier substrate to provide sustained release. A method of controlling elevated intraocular pressure with these compositions is also described.

    摘要: The present invention provides a portable, temporary railroad signaling device which may be tenaciously secured onto a railroad rail and its use. The device includes an adjustable and fixed clamping mechanism for clasping onto a railroad rail placed therewithin, which mechanism when tightly drawn together mechanically biases and wedges the rail therebetween. The device advantageously includes a collapsible arm to mount and support a signaling unit thereupon an internal housing for stowing a signaling unit therewithin and a lock for locking the clamped device onto the rail to protect the device against unauthorized tampering.
