1. Effect of triiodothyronine and GC-1, a thyroid hormone receptor b-selective thyromimetic, on histomorphometric and biomechanical parameters of bone tissue of adult rodents. / Efeito da triiodotironina e do GC-1, um tireomimético seletivo pela isoforma b do receptor de hormônio tireoideano, sobre parâmetros histomorfométricos e biomecânicos do tecido ósseo de roedores adultos.
Adult rats were treated with 2.5, 5, 10, 20 and 40x the physiological dose of triiodothyronine (T3) for 10 weeks. There was a dose-dependent reduction in bone mass, trabecular volume and thickness (Tb.Th), and cortical thickness. Up to 10xT3, there was an increase in the bone formation rate (BFR). Higher doses of T3 decreased BFR and bone resorption. These d
