    摘要: A cryosurgery device for dispensing a liquid refrigerant from a container having a valve stem extending outwardly therefrom. The device includes an actuator adapted to seat on the valve stem of the container in order to depress the valve stem to release the refrigerant from the container. The actuator includes an inner passageway having opposed ends disposed therein, one of the ends of the passageway being in fluid communication with the valve stem. An applicator tube is mounted to the actuator at the other end of the inner passageway. A cap is disposed on the top of the container. The actuator is movably positioned on the cap and a shield is attached to the cap to completely receiving the applicator tube. Liquid refrigerant can only be dispensed when the actuator is positioned properly and the applicator tube is disposed within the shield means.

    摘要: A solution-based assay for determining the presence of peroxidatively-active substance in a bodily fluid is described. The solution-based assay contains a spectrophotometric substrate, a hydroperoxide, a pH 6.0-7.0 buffer, a surfactant, and a solvent such as DMSO, THF, DMF, or mixtures thereof, with the balance of the solution being water. The solution-bascd assay is particularly useful in qualitative and quantitative assays for urinary hemoglobin. Solution-based assay kits and assay methods are also described.
