Figure 2.

A-C) Serum T3, T4, and TSH levels for PTU treated animals. Both T3 and T4 levels were significantly decreased with exposure to 3 and 10 ppm PTU at all exposure durations with corollary increase in TSH at 3 and 10 ppm at 7 and 14-day exposures only. D-F) T3, T4, and TSH levels in the serum of MMI treated animals. Exposure to 30 and 200 ppm MMI significantly reduced serum T3 and T4 at all exposure durations with significant increase in TSH with exposure to 30 and 200 ppm for 7 and 14 days and 30 ppm only for 4 days. The bar graphs are presented as mean ±SEM and statistically significant is designated as *p<0.05 N=8 per dose/time-point.
