Abstract: A single laser flow cytometric method for the enumeration of micronuclei in erythrocyte populations, wherein a sample of peripheral blood or bone marrow is obtained and the cell populations in the sample are fixed. Reticulocytes in the fixed samples are treated simultaneously with RNAse and with a fluorescent labeled antibody having binding specificity for a surface marker for erythroblasts/reticulocytes. The erythrocyte populations are then stained with a nucleic acid stain which stains DNA representing micronuclei, if present. The stained and/or labeled erythrocyte populations are then exposed to a laser beam of appropriate excitation wavelength for both the nucleic acid staining dye and the fluorescent label to produce fluorescent emission. The fluorescent emission and light scatter produced by the erythrocyte populations are detected by the flow cytometer from which is calculated the number of specific erythrocyte populations in said sample.

Abstract: A gelatinous composite article has a sealant layer, a permeable layer and a heat formable and heat reversible gelatinous elastomer material. The sealant layer melts within a first temperature range. The permeable layer is over the sealant layer and melts at a second temperature greater than the first temperature range. The heat formable and heat reversible gelatinous elastomer material is over the permeable layer and fuses to the sealant layer within the first temperature range. The sealant layer and the gelatinous elastomer material adhere to each other through the permeable layer once the first temperature is attained. Thereby, the permeable layer secures to the gelatinous layer.

Abstract: A chemical oxygen or other gas generator which has a container composed of thermally-conductive and gas-impervious material which contains pyrotechnic material, the container being in heat transfer relation with a block of oxygen-producing material for transfer of heat from burning of the pyrotechnic material within the container directly to the block of oxygen-producing material for initiation of decomposition thereof. The container is sealingly attached to the casing so that all of the evolved gases from burning of the pyrotechnic material are segregated from the produced breathable oxygen. The evolved gases are vented from the oxygen generator so as to reduce the ignition chamber pressure and/or allow a greater amount of pyrotechnic material to be burned within the ignition chamber so that a sufficient amount of heat may be generated within the ignition chamber for application to the block of oxygen producing material for initiation of decomposition thereof.
