Radioactivity was measured in tissues and serum of diestrous females (Figure 1; see also Table S1) and of males (Figure 2; see also Table S2) that received a sc injection of TBBPA followed by a dietary supplement of [sup.14]C-BPA.
Radioactivity was measured in the tissues of diestrous females (Figure 3, Table 2; see also Table S3) and of males (Figure 4, Table 2; see also Table S4) that received a sc injection of TBBPA, triclosan, or both followed by a dietary supplement of [sup.14]C-BPA.
Urinary E2 concentrations of diestrous females (Figure 5; see also Table S5) and of males (Figure 6; see also Table S6) were measured after a sc injection of vehicle or TBBPA.
Mean (+ SE) concentration of [sup.14]C-bisphenol A (BPA) in the heart, lung, muscle, adipose, uterus, ovaries, and serum of diestrous females following subcutaneous (sc) injection of vehicle, 1, 3, 9, or 27 mg tetrabromobisphenol A (TBBPA) and subsequent dietary administration of 50 [micro]g/kg [sup.14]C-BPA (n = 7 per dose).
Mean (+ SE) concentration of [sup.14]C-bisphenol A (BPA) in the heart, lung, muscle, adipose, uterus, ovaries, and serum of diestrous females following subcutaneous (sc) injection of vehicle, 0.33 mg triclosan, 0.33 mg tetrabromobisphenol A (TBBPA), or 0.33 mg triclosan + 0.33 mg TBBPA and subsequent dietary administration of 50 [micro]g/kg [sup.14]C-BPA (n = 7 per dose).
Mean (+ SE) concentration of urinary E2, expressed as nanograms 17[beta]-estradiol (E2)/milliliter urine and nanograms E2/milligram creatinine, following subcutaneous (sc) injection of vehicle or 1 mg tetrabromobisphenol A (TBBPA) in diestrous females (n = 15 per dose).
However, the animals from groups II and III were observed as having a stressed incidence in the estrous phase, with a percentage of 34,50% and 20,85%, respectively, and the increase of the diestrous phase with 64,58% for group II, and 75,00% in group III.
Regarded to the reduction of the estrous phase and increase of the diestrous phase, besides the appearance of the proestrous phase in the animals of group II, observed in graphic 2, this can be related to the retaken of the nocturne release of melatonin in these animals, because, according to Johnson et al.
