In the experiments on the effects of EO on gastric emptying, gastrointestinal hormones and CRF in rats subjected to restraint stress, 40 model rats were randomly divided into four groups (n = 10): three EO treatment groups (30, 60, 120 mg [kg.
To investigate whether the EO affects gastrointestinal hormones of delayed gastric emptying, we further observed the effects of the EO on the levels of circulating MTL, SS, VIP and GAS in rats subjected to restraint stress stimulation.
Gastrointestinal hormones are regulated by the autonomic nervous system, the vagal nerve in particular.
However, more recently, van der Sjip et al (44) found no difference in circulating levels of a panel of upper gastrointestinal hormones, including neurotensin, motilin, gastrin, and pancreatic polypeptides, though they did show alterations in somatostatin.
This upper gastrointestinal dysmotility may be part of a pangastrointestinal abnormality, or it may result from abnormal circulating levels of neuropeptides and/or noncolonic gastrointestinal hormones.
