ABSTRACT
<p><b>AIM</b>To probe into the operation mechanism of stress, through the studies on the effects of bile secretion in rats at the condition of water immersion restraint.</p><p><b>METHODS</b>The animals were divided into six groups (n=8) Group A restraint alone under room temperature + saline; Group B water immersion restraint + saline; Group C restraint alone under room temperature + Atropine; Group D water immersion restraint + Atropine; Group E restraint alone under room temperature + Phentolamine; F group water immersion restraint + Phentolamine.</p><p><b>RESULTS</b>Compared with group A, the capacity of bile secretion in group B decreased significantly (P < 0.05), changes of bile increased remarkably (P < 0.01), but there were no significant decreases on the capacity of bile secretion in group C (P > 0.05) compared with A, Group C only decreased appreciably. Compared with group A, the capacity of bile secretion in group E decreased appreciably (P < 0.05). Compared with group B, the capacity of bile secretion in group D decreased significantly (P < 0.05), pH of bile had no significant changes in group D. Compared with group B, the capacity of bile secretion in group F decreased significantly (P < 0.05), pH of bile had no significant changes in group F. Compared with group D, the capacity of bile secretion and pH of bile in group F had no significant changes.</p><p><b>CONCLUSION</b>Water immersion restraint stress inhibited evidently on the capacity of bile secretion, and the capacity of bile secretion in water immersion groups decreased significantly, moreover pH of bile increased greatly. At the condition of restraint alone under room temperature, vagus and sympathetic nerve had no significant effects on the bile secretion, but they played important roles in decreases of bile secretion evidently induced by water immersion restraint stress in rats (P < 0.05).</p>
