Abstract: To optimize the .sup.14 C-urea breath test for Helicobacter pylori (a) a collection method for alveolar breath samples, (b) varying the post-dosage breath collection time and (c) varying the concentrations of KOH in the liquid trap employed for the capture of .sup.14 CO.sub.2 are employed. Collection of alveolar breath samples in bags was convenient for user and patient. The test provided optimal sensitivity and specificity for the detection of H. pylori infection when breath collections were performed 10 min after dosage with .sup.14 C-urea, and when breath CO.sub.2 was captured in liquid traps containing 80 or 800 mM KOH.

Abstract: The treatment of blood and other body fluids and tissues, the detection of tumors and the treatment of patients is disclosed. The treatment and detection involve the use of families of chlorins, families of purpurins and families of metal complexes of chlorins and purpurins. The purpurins and their metal complexes have the structures of FIGS. 1 , 7, 14-18, 29-38, 44-48 and 54-58 of the attached drawings. The chlorins and their metal complexes have the formulas of FIGS. 2 , 8, 19, 20, 22, 23, 24, 25, 27, 28, 39, 40, 42, 43 and 49-53 of the attached drawings. Solutions of the purpurins, of the foregoing and other chlorins and of the metal complexes which are physiologically acceptable for intravenous administration are also disclosed, as are emulsions or suspensions of the solutions. The solvent for the solutions can be a product of the reaction of ethylene oxide with castor oil.

Abstract: An enclosure for a bed to provide protection for patients who would have otherwise required soft restraints to prevent self injury. The enclosure is formed of a supporting framework and an associated covering provided with suitably arranged zippered areas for achieving access to the patient from the exterior of the enclosure.
