treatment of rats with triiodothyronine ( t3 10 micrograms/100 g per day , 20 days ) increased the mass of brown adipose tissue ( bat ) and heart ventricle and stimulated beta-adrenoreceptor number ( assessed from radioligand binding ) by 43 % in isolated bat and heart membranes . alpha-receptor number was slightly increased in bat membranes ( 42 % ) but reduced in heart from t3-treated rats .
