"Acute dose" nghĩa là gì?
20 May, 2023
"Acute dose" = liều cấp tính -> nghĩa là phơi nhiễm với phóng xạ trong thời gian ngắn nhưng đến mức không thể phục hồi về mặt sinh học được nữa.
Ví dụ
Prenatal exposure to ionizing radiation may induce brain damage in foetuses (bào thai) following an acute dose exceeding 100 mSv between weeks 8-15 of pregnancy and 200 mSv between weeks 16-25 of pregnancy.
To our knowledge, this is the first reported comparison on the effects of a one-time high acute dose vs a lower chronic (thường xuyên) daily dose, consisting of a tenfold dilution (làm giảm) of an overnight culture given for 6 days, in an animal model.
These findings indicate that both the single acute dose and the chronic lower dose of E. coli 62-57nal caused varying degrees of a similar dysbiosis.
The study, “Acute dose-dependent effects of lysergic acid diethylamide in a double-blind placebo-controlled study in healthy subjects“, was authored (tạo ra) by Friederike Holze, Patrick Vizeli, Laura Ley, Felix Müller, Patrick Dolder, Melanie Stocker, Urs Duthaler, Nimmy Varghese, Anne Eckert, Stefan Borgwardt, and Matthias E. Liechti.
