Abstract: A composition useful as an imaging agent comprises a beta adrenergic receptor antagonist compound, preferably iodopindolol, to which is covalently attached an iodine radioisotope such as .sup.123 I or .sup.124 I. This composition is used in a method for radioimaging beta adrenergic receptors in a tissue, preferably brain. In particular, the method is useful with the radioimaging technique of single photon emission computed tomography (SPECT) or positron emission tomography (PET). The above composition, as well as a kit comprising a set of one or more standard radiographic images of beta adrenergic receptors, are also useful in methods for (1) diagnosing an alteration in beta adrenergic receptors in a tissue, particularly brain; (2) diagnosing suicidal depression in a subject; and (3) detecting the therapeutic normalization of beta adrenergic receptor expression in a subject.

Abstract: The fire fighting and hot surface cooling methods of this invention use a composition formed by combining a nonionic surfactant possessing a specific photoexcitable functional group with an arylphosphate, also of photoexcitable nature, in a solvent medium of composition and content that allows for a convenient workable viscosity and is resistant to effects of freezing. The ultimate water solution used for spraying to extinguish a fire or cool a surface contains from 2000 ppm of the surfactant nonylphenolethoxylate and 94 ppm of the arylphosphate, poly(oxy-1,2-ethanediyl), .alpha.-phenol-.omega.-hydroxy-(2)-phosphate to 3000 ppm surfactant and 141 ppm arylphosphate. The spray solution is applied to the fire until the desired result occurs.

Abstract: 5,7-Diamino-4,6-dinitrobenzofuroxan is synthesized in high yield by aminan of 7-amino-4,6-dinitrobenzofuroxan with hydroxylamine in the presence of strong base such as potassium hydroxide. Acidification of the potassium salt produces a fine powder. Recrystallization of the powder by an extraction process under vacuum in solvents such as dimethylformamide results in large, cube-like crystals which can be pressed to high density explosive formulations. These explosive formulations show high performance as explosives.
