[The psychotropic action of TRH]

During a double-blind trial about using TRH perfusions, the authors didn't established any antidepressive effect. On the other hand they observed an anxiety reaction under a 1,200 microgram in perfusion. The study of the basic level of T3, T4, T.S.H. and Prolactin corroborated the normality of the biological evaluation among the depressed. No difference of the hormonal response under T.R.H. was established depending on different types of depression. The authors reported that the Prolactin respons is higher among the subjects for whom the T.R.H. was the more distressing.
