The role of the thyroid hormones on the decrease of cholesterolemia produced by a thymus fraction

The purpose of this paper is to establish whether the hypocholesterolemic effect of thymus fraction administered to rats fed on a fat diet is correlated to an activation of thyroid. By determining the plasma levels of T3,T4 by kit set/RIA and TSH by the method of Jaquet et al., modified for rats, the authors may exclude this hypothesis confirming the results of Comsa et al, of an inhibitory effect of thymus in TSH secretion.
