METHODS: We measured thyroid hormone parameters [thyroid stimulating hormone (TSH), free thyroxine (fT (4)), total triiodothyronine (T (3)), thyroxine-binding globulin (TBG)] and concentrations of several contaminants [PCB-153, hydroxylated metabolites of PCBs (HO-PCBs), pentachlorophenol (PCP) and hexachlorobenzene (HCB)] in maternal plasma at delivery (n = 120), in umbilical cord plasma (n = 95), and in infant plasma at 7 months postpartum (n = 130).

Serum was collected every 2 weeks and at 27 weeks every 15 min for 6 h during both day and night, and for 1 h before and 5 h after stimulation with GnRH, adrenocorticotrophic hormone and thyroid-stimulating hormone.

The effects on thyroid hormone status were more pronounced after 4 weeks and also included increased thyroid stimulating hormone (TSH) levels.
The major metabolite pentachlorophenol (PCP) also caused, by competitive interactions with thyroid hormone binding proteins in serum, a rapid and dose-dependent decrease of TT4 and FT4 levels, but not of TT3 levels in serum.

Serum was collected every 2 wk. during development, daily during the synchronized cycle and frequently (every 15-60 min) for 6-18 h either with or without stimulation with thyroid-stimulating hormone (TSH) during the synchronized luteal phase or TSH/thyroid-releasing hormone (TRH) at 65-66 wk of age.

After weaning, 6 ewes from each group were bled at 15-min intervals for 8 h during the day and night and for 1 h before and 5 h after i.v. administration of gonadotropin-releasing hormone, thyroid-stimulating hormone (TSH), and adrenocorticotropin, to measure serum concentrations of luteinizing hormone, follicle-stimulating hormone, thyroxine (T4), and cortisol.

19082768 Kawaguchi M, Morohoshi K, Saita E, Yanagisawa R, Watanabe G, Takano H, Morita M, Imai H, Taya K, Himi T: Developmental exposure to pentachlorophenol affects the expression of thyroid hormone receptor beta1 and synapsin I in brain, resulting in thyroid function vulnerability in rats. Endocrine. 2008 Jun;33(3):277-84.

Gene expressions of thyroid hormone receptor beta1 and synapsin I, factors that promote brain growth, was increased in the cerebral cortex of PCP-treated weanling females, whereas plasma concentrations of total thyroxine were decreased in dams and weanling pups, and plasma thyroid-stimulating hormone concentrations were higher in PCP-treated weanling males.
