“Also following cervical sympathectomy, T3 caused a reduction of the T/M for choline , to the same level as in the non-sympathectomized animals, while the effect of T3 on the Na+-K+-ATPase activity was changed into a 22% decrease.”
“The major effect of T3 on the choline uptake may be exerted by a mechanism different from the ATPase activity and not involving adrenergic receptors.”
