[Effect of exogenous somatotropin on the ultrastructure of somatotropic cells in hyperthyroid rats].
Problemy endokrinologii, 32(2): 77-8 PMID 3714683
Abstract
Marked ultrastructural changes indicating a decrease in the cell functional activity occur in the somatotropic cells of rats after chronic hyperthyroidism with 1-thyroxin. Exogenous somatotropin produces no effect on these ultrastructural changes.
