    Abstract: Taking a bodily sample from deep within the body of a patient and collecting the sample outside the body to facilitate treatment of the patient. A sampling probe is provided in the form of an elongate catheter having a proximal portion that remains outside the body and a distal portion that can be located within the body. The distal portion includes a membrane with openings that communicate with space that communicates with a source of suction force. The catheter is positioned within the body. The sample is taken by exposing the membrane by placing it in proximity with a desired location so that the bodily sample is received by the membrane. The catheter is removed from the patient and the sample is collected outside the body.

    Abstract: Solid compositions are disclosed comprising a complex of water; a benzotriazole of the formula ##STR1## wherein R.sup.1 and R.sup.2 are independently hydrogen, a monovalent organic radical, halogen, or nitro; and at least one water-soluble base having a basicity greater than that of the benzotriazole and capable of dissociating to provide an anion and a monovalent or divalent metal cation. The compositions have melting ranges above 35.degree. C. and are capable of releasing a substantial portion of the water contained therein to the surrounding environment when melted. The compositions can be employed in thermally developable photographic film units as thermally induced water-releasing materials which provide water to the internal environment of the film unit when the film unit is heated sufficiently to melt the composition.
