Selenium levels and glutathione peroxidase activity were determined in blood and reproductive organs in 12 Norwegian dairy cows at different stages of the oestrus cycle. Blood samples were collected before slaughter, and samples from genital organs were obtained as soon as possible after slaughter. Blood and plasma selenium levels were significantly correlated with selenium levels in follicular fluid, and in ovarian and uterine tissues, but not with the levels in corpora lutea. The activity of blood glutathione peroxidase was significantly correlated with that in ovarian and uterine tissue, but not with activity in corpora lutea and follicular fluid. No effect of stage of oestrus cycle on selenium content or glutathione peroxidase in reproductive tissue was observed.
对12头处于发情周期不同阶段的挪威奶牛的血液和生殖器官中的硒水平及谷胱甘肽过氧化物酶活性进行了测定。在屠宰前采集血样，屠宰后尽快获取生殖器官样本。血液和血浆中的硒水平与卵泡液、卵巢和子宫组织中的硒水平显著相关，但与黄体中的硒水平无关。血液谷胱甘肽过氧化物酶的活性与卵巢和子宫组织中的活性显著相关，但与黄体和卵泡液中的活性无关。未观察到发情周期阶段对生殖组织中硒含量或谷胱甘肽过氧化物酶的影响。
