    Summary

    Neurohumoral changes, including catecholamines and acetylcholine, occur early in acute intestinal obstruction. Sympathetic activity increases as the condition progresses, impacting neurotransmitter levels.

    Area of Science:

    • Gastroenterology
    • Neuroendocrinology
    • Physiology

    Background:

    • Acute intestinal obstruction is a critical condition with significant physiological consequences.
    • Neurohumoral dysregulation is implicated in the pathophysiology of intestinal ileus.
    • Understanding these changes is crucial for effective management.

    Purpose of the Study:

    • To investigate neurohumoral alterations in patients and animal models of acute intestinal obstruction.
    • To determine the temporal dynamics of these changes during the disease course.

    Main Methods:

    • Analysis of catecholamines, acetylcholine-like substances, serotonin, and histamine in blood plasma.
    • Assessment of their metabolism products.
    • Cardiointervalography for evaluating autonomic nervous system activity.

    Main Results:

    • Neurohumoral changes manifest in the early stages of intestinal obstruction.
    • Changes progress with the duration of the disease.
    • Decreased acetylcholine-like substances correlate with prevailing sympathetic activity.
    • Serotonin and histamine metabolism are stage-dependent.

    Conclusions:

    • Early neurohumoral alterations are characteristic of acute intestinal obstruction.
    • Autonomic nervous system imbalance, particularly sympathetic dominance, is a key feature.
    • Further research into targeted interventions based on these neurohumoral profiles is warranted.
