Immunogenicity and safety of recombinant yeast-derived hepatitis B vaccine in haemodialysis patients

The objectives of the present study were: 1) to describe the modifications in motility of the small intestine in response to situations of acute physical stress during fasting and post-prandial period; 2) to analyse the possible involvement of the adrenergic and beta-endorphinergic systems in these modifications. For this we used a total of 60 dogs. We can conclude that acute physical stress does indeed modify the normal motility of the small intestine, both in the fasting and post-prandial periods. Beta-endorphin is implicated in the hypermotility response and catecholamines are involved in the hypomotility effect
