When smoke from single cigarettes containing [4-14C]cholesterol or beta-[4-14C]sitosterol was delivered to the lungs of Rhesus macaques, plasma contained radiolabeled sterols up to 50 days later. Since cholesterol, as well as plant sterols (campesterol, stigmasterol and beta-sitosterol), are normally present in cigarette smoke, our observations suggest that protracted absorption of sterols occurs after cigarette smoking.
当含有[4-¹⁴C]胆固醇或β-[4-¹⁴C]谷甾醇的单支香烟烟雾被输送到恒河猴肺部时，50天后血浆中仍含有放射性标记的甾醇。由于胆固醇以及植物甾醇（菜油甾醇、豆甾醇和β-谷甾醇）通常存在于香烟烟雾中，我们的观察结果表明，吸烟后甾醇会持续被吸收。
