THORACIC OESOPHAGEAL MOTOR ACTIVITY DURING ERUCTATION IN SHEEP

Pressure profile along the oesophagus during eructation in sheep.

The pressure profile along the oesophagus was recorded simultaneously with the flow rate of eructated gas in sheep to evaluate the oesophageal motor events leading to the relief of gas. All the eructation sequences started by a rise followed by a plateau of oesophageal pressure. The passage of gas at the tracheal level occurred during this plateau and not during the consecutive transient loweri...

Inco-ordination of oesophageal motor activity.

Physiology of the oesophagus The oesophagus is essentially a motor organ and oesophageal disease often results in disordered motor function. Under resting conditions the gullet is normally sealed at its upper and lower extremities by sphincters which relax in a coordinated manner before the oncoming bolus. The oesophageal peristaltic wave travels at 2-3 cm/sec and is initiated either by swallow...

Spontaneous Motor Activity in the Fetal Sheep

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Oesophageal and gastric motor activity in patients with bulimia nervosa.

Previous studies showed that symptoms of oesophageal motor disorders can be misinterpreted as indicating anorexia nervosa and that in primary anorexia nervosa gastric motility is frequently impaired. We investigated in 32 women with bulimia nervosa whether symptoms of oesophageal motor disorders could be obscured by or be mistaken as forming part of bulimic behaviour, and whether impaired gastr...
