饲以商品饲料的雄性叙利亚金黄田鼠,体重100克,每周在麻醉下气管内滴注3毫克苯(d)并芘(BP)(黏着于3毫克的 Fe_2O_3上面,用0.2毫升生理盐水制成悬液),共12周。在灌注期间,悬液内 BP含量以及实际注入气管内的 BP 量均经校正。最末一次滴注后,将田鼠随机分为三组:每周维生素 A(Retinyl acetate)灌胃100微克(1组),1600微克(2组)及3300微克(3组)。均每周分二次灌胃,直到实验
Male Syrian Golden Warbler fed on commercial diet, weighing 100 grams, was intratracheally instilled 3 mg of benzodiazepine (BP) per week under anesthesia (adhering to 3 mg of Fe 2 O 3, made of 0.2 ml of physiological saline Suspension) for 12 weeks. During perfusion, the amount of BP in the suspension and the amount of BP actually injected into the trachea were corrected. After the last instillation, the voles were randomized into three groups: 100 μg (group 1), 1600 μg (group 2) and 3300 μg (group 3) of gavage weekly. Gavage twice a week until the experiment
