[Effects of pentobarbital on serum PRL and TSH in the basal condition and under TRH stimulation in man: preliminary note].

The Authors have tested serum levels of PRL and TSH in six healthy males, anaesthesized with 20 mg./Kg. body weight of pentobarbital with and without stimultion with TRH. PB has no effect on serum levels of TSH but there is an inhibition of PRL release 180', 240' and 360' after the administration of the drug. The AA. have found no effects of PB on the stimulation test with TRH. All the data obtained have been examined with Student's "T" test.
