[The time-concentration relationship of serum bisphenol A in male rats].

Objective: To investigate the relationship of time-concentration of bisphenol A (BPA) in male Sprague-Dawley (SD) rats after single oral BPA administration.

Methods: A total of 66 specific pathogen free (SPF) SD male rats were divided into 10 experimental groups and control group (n = 6). The experimental group rats were treated with BPA of 300 mg/kg by oral gavage and blood samples were taken from one group at 0.
