In a lifetime experiment benzo(a)pyrene (B(a)P) was administered to Sprague-Dawley rats either as an admixture to the diet or by gavage in an aqueous 1.5% caffeine solution. Dissolved benzo(a)pyrene induced more tumors of the forestomach than undissolved benzo(a)pyrene. The 1.5% caffeine solution (annual dose 27 g/kg) did not exert any carcinogenic activity under the conditions of this bioassay.
在一项终生实验中,将苯并(a)芘(B(a)P)以混入饲料的形式或通过用1.5%咖啡因水溶液灌胃的方式给予斯普拉格-道利大鼠。溶解的苯并(a)芘比未溶解的苯并(a)芘诱发更多的前胃肿瘤。在本生物测定条件下,1.5%咖啡因溶液(年剂量27 g/kg)未表现出任何致癌活性。
