3. Effects of baclofen on the Hering-Breuer inspiratory-inhibitory and deflation reflexes in rats

Author

Seifert, Erin and Trippenbach, Teresa

Subjects
Respiration -- Regulation, Respiratory center -- Physiological aspects, Biological sciences
Abstract

The effects of the gamma-amino butyric acid (GABA) agonist baclofen applied directly on the nucleus of the tractus solitarius on the Hering-Breuer inspiratory-inhibitory and deflation reflexes were examined using anesthetized rats. Results reveal that baclofen attenuates but does not abolish these reflexes indicating that GABA receptors modulate the control of these reflexes.

4. Ventilatory and metabolic effects of repeated hypoxia in conscious newborn rabbits

Author

Trippenbach, Teresa

Subjects
Hypoventilation -- Analysis, Rabbits -- Physiological aspects, Biological sciences
Abstract

A study of metabolic and ventilatory effects in newborn rabbits reveals that moderate hypoxia, which does not reduce the rabbit's sensitivity to oxygen deficiency, does not cause prolonged posthypoxic depression of body metabolism and ventilation. Moderate hypoxia enhances inhibitory neurotransmitter levels. Repeated hypoxia is conducive to respiratory system recovery which is essential for the survival of newborn rabbits.

5. Effects of cute and chronic cocaine on breathing and chemosensitivity in awake rats

Author

Trippenbach, Teresa and Kelly, Gisele

Subjects
Respiration -- Analysis, Cocaine -- Physiological aspects, Biological sciences
Abstract

A study of awake rats reveals that cocaine interaction with the dopaminergic system possibly causes the cocaine-induced respiratory excitation that is possibly linked with behavioral arousal. While acute cocaine possibly increases alveolar ventilation under conditions of hypoxia and hypercapnia, chronic cocaine may reduce peripheral chemosensitivity, thereby causing respiratory depression.

6. Changes in extracellular (K+) and (Ca2+) induced by anoxia in neonatal rabbit medulla

Author

Subjects

Abstract

The effects of anoxia in extracellular concentrations of potassium ((K+)O) and calcium ((Ca2+)O) were studied in the medulla of newborn rabbits using ion-selective microelectrodes to monitor changes in the ion levels. Anoxia produced an age-dependent decrease in both (K+)O and (Ca2+)O resting concentrations in the brain stem confirming the neonatal brain's high resistance to oxygen deprivation.

32. Pulmonary Reflexes and Control of Breathing during Development

Author

Trippenbach, Teresa

Abstract

The potency of the Hering-Breuer inspiratory-inhibitory and expiratory-promoting reflexes decreases with maturation in mammals. The Hering-Breuer deflation reflex is present at birth and its power changes little during postnatal development. Already during the second day of life the airway defence reflex resembles that of the adult rabbits. In contrast, sensitivity of the pulmonary chemoreflex does not reach the adult level by the end of the first week of life in newborns of the same species. The time course of functional development of respiratory reflexes coincides with the maturity of different species at birth.

33. Effects of Hypoxia on Phrenic Neurogram Response to Vagal and Somatic Stimulation in Newborn Rabbits

Author

Trippenbach, Teresa

Abstract

Effects of 10% O2 on the response of the phrenic neurogram to vagal (VS) and saphenous stimulation (SS) were studied in anesthetized and artificially ventilated newborn (group 1: 1–3 days old, n = 13; group 2: 8–14 days old, n = 14) and adult (group 3, n = 12) rabbits. In all animals during ventilation with 100% O2 or 10% O2 in N2, VS caused a reduction in the expiratory phase (Te). Te shortening in response to SS was unaffected by hypoxia in group 3, and was abolished in group 2. In group 1 only early hypoxia blocked the Te response to SS. The preserved Te response to VS on one hand, and abolished the effects of SS on the other, suggest that blockade of the somatic inputs is due to the age-dependent action of hypoxia in areas distant to the respiratory neurons.
