In order to observe the effect of acute hypoxia on blood vascular of endothelial cell (VEC) count, acute hypoharic hypoxia experiment was carried out in 16 healthy pilots. Venous blood was taken 30min before, immediate after, 2h after hypoxie exposure for VEC count. VEC was identified by immuno-fluoreseent staining with rahit‘s anti-human Ⅷ factor rebated antigen. 相似文献

SummaryAfter a priming dose of 300 rads, a response curve for chromosome exchanges has been obtained at the time of minimal dose interaction.Compared with a single-exposure dose-response curve induced at the same time, the fractionated curve is displaced downwards, since there is no interaction at any dose combination. It also shows pronounced saturation at higher total doses, suggesting a reduction in the number of effective exchange sites available to the second dose. Further evidence for such a reduction comes from the observation that the observed yields are consistently below those expected on the basis of simple additivity of the yields from the two dose fractions.Assuming that the original population had a limited number of effective exchange sites, the loss of interaction is shown to be consistent with the repair of partially damaged sites, but the data do not exclude the possibility that dose-dependent site inactivation is also a contributing factor. 相似文献

SummaryThe cytotoxic effects of X-irradiation may be delayed for many generations of replication in mammalian cells. In addition to a reduced cloning efficiency, progeny of surviving Chinese hamster ovary (CHO) cells isolated after 12–34 population doublings postirradiation showed a variety of abnormalities including lower attachment ability to culture dishes and slower cell cycle progression. When these progeny were seeded as single cells 12–23 generations after irradiation, they formed a higher fraction of abortive colonies and of non-homogeneous colonies containing giant cells. All of these characteristics were evident whether progeny cells were subcultured by trypsinization or by mitotic selection. These results suggest that residual damage may be carried by surviving progeny of irradiated cells over many mitotic cycles; this damage is eventually expressed in terms of pleomorphic changes leading to delayed reproductive failure. 相似文献
