【摘要】 小鼠２４ｈ暴露于低浓度臭氧环境中，１周后小鼠心、脑脂褐质含量（１０．９±１．７、８．６±１．７μｇ／ｇ）明显高于对照组小鼠心、脑脂褐质含量（８．１±１．５、６．９±１．６μｇ／ｇ）（Ｐ＜０．０１）。而给暴露在臭氧环境中小鼠每日喂以５ｍｇ／ｋｇ维生素Ｃ后，小鼠心、脑脂褐质含量（８．３±０．８、５．２±０．７μｇ／ｇ）明显低于臭氧组（Ｐ＜０．０１），与对照组相比较无显著性的差异（Ｐ＞０．０５）。更多还原

【Abstract】 In the study,mice were exposed to the low ozone condition for a week. The lipofuscin content in mice heart and brain (10.9±1. 7 and 8. 6±1. 7μg/g) were markedly higher than that of control group (8. 1±1. 5 and 6. 9±1. 6μg/g), P<0. 01. However,the lipofuscin content (heart: 8. 3±0. 8μg/g ; brain: 5. 2±0. 7μg/g) in mice exposed to low ozone concentration and fed Vitamin C were lower than only exposed to ozone, and there were no significant,when it were compared with the control group.更多还原
