Recovery from disorders of respiratory activity in cats using thyroliberin

Controlled lung hyperventilation in cats inhibited the activity of the diaphragm muscle with a subsequent stop of respiration after the end of hyperventilation. Thyroliberin (20-30 mg/kg) intravenously was shown to abolish these effects 15-20 min after application. Preliminary introduction of thyroliberin prevented the changes in the respiration rate and depth caused by vagotomy.
