Based on a correlation of serum testosterone levels and cortical cyclic-AMP concentrations in a normal aging population of male CD Fischer rats and a demonstration of decreased cortical cyclic-AMP subsequent to injection of testosterone, it was concluded that a cause and effect relation between hormone concentrations and brain cyclic nucleotide levels is tenable.
基于对雄性CD费舍尔大鼠正常老龄种群血清睾酮水平与皮质环磷酸腺苷浓度的相关性研究,以及注射睾酮后皮质环磷酸腺苷浓度降低的证明,得出激素浓度与脑环核苷酸水平之间存在因果关系的结论。
