    Preflight studies on tolerance of pocket mice to oxygen and heat. II - Effects on lungs (1975)

    Beschreibung: An electron microscope examination was carried out on the lungs of 11 pocket mice (Perognathus longimembris) that breathed oxygen at 10 psi or 12 psi partial pressure over a period of 7 d, at the end of which time they were decompressed to sea-level O2 pressure, either suddenly or in 30, 60, or 90 min. Vesiculation was noted in the endothelium of the alveolar-capillary wall in most of the animals and, occasionally, blebbing. Some mitochrondria were swollen in a few of the animals. Alveolar exudate was, in general, sparse. Compared with the lungs of other rodents, the lungs of pocket mice appeared relatively resistant to the toxic effects of oxygen. This conclusion needs, however, to be tempered by the fact that 5% N2 was used in the tests reported here. Nonetheless, the results suggest that the oxygen pressures anticipated on the flight of Apollo XVII should be well tolerated by the pocket mice.

    Cosmic ray effects on the eyes of rats flown on Cosmos no. 782, Experiment K-007 (1978)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-06-27
    Beschreibung: A study was undertaken to determine if, and to what extent, pathological damage results from high-energy particles (HZE) transversing the eye. Light flashes experienced by space travellers indicate that HZE do indeed pass through and activate the retina, but whether actual biological damage occurs has not been investigated thoroughly. Thus, autopsies were performed on the eyes of rats which has been flown in Cosmos 782 satellite for 19.5 days. Comparisons with a control sample subjected to 1000 rads of Ar and Ne radiation show that pathological damage, when it occurs, affects the nucleus of the retina; simple light flashes are not thought to indicate a pathology, and result from activation of (but not damage to) the retina's outer segments.
