The urinary excretion of cyclic 3'5'-adenosine monophosphate (cAMP) was measured in rats provided a low fluoride diet (less than 0.5 ppm) and drinking water containing either 0 or 25 ppm of fluoride. The pMole cAMP/microgram creatinine ratio decreased with age but was not influenced by fluoride intake.
在给予低氟饮食（低于0.5 ppm）且饮用水中氟含量为0或25 ppm的大鼠中，测定了环磷酸腺苷（cAMP）的尿排泄量。每微克肌酐中cAMP的皮摩尔比值随年龄降低，但不受氟摄入量的影响。
