Salivary flow in borderline hypertension.

R Böhm, M van Baak, M van Hooff

    Klinische Wochenschrift
    |January 1, 1985
    PubMed
    Summary

    Saliva production is reduced in individuals with borderline hypertension, indicating a potential decrease in parasympathetic nerve activity affecting salivary glands. This finding highlights differences in salivary function between hypertensive and normotensive subjects.

    Area of Science:

    • Physiology
    • Cardiovascular Science
    • Pharmacology

    Background:

    • Salivary flow regulation involves complex neural pathways.
    • Hypertension is a widespread cardiovascular condition.
    • Autonomic nervous system dysfunction can impact salivary gland function.

    Purpose of the Study:

    • To investigate salivary flow rates in normotensive and hypertensive individuals.
    • To examine the effects of specific autonomic drugs on salivary secretion.
    • To assess parasympathetic influence on salivary glands in borderline hypertension.

    Main Methods:

    • Comparative study of salivary flow rates in normotensive and borderline hypertensive subjects.
    • Administration of autonomic agents: propranolol, phentolamine, noradrenaline, atropine, and neostigmine.
    • Measurement of salivary flow parameters.

    Main Results:

    • Lower salivary flow rates were observed in borderline hypertensives compared to normotensives.
    • Atropine significantly decreased salivary flow.
    • Neostigmine's stimulatory effect on saliva production was diminished in borderline hypertensives.

    Conclusions:

    • Data suggest reduced parasympathetic innervation to salivary glands in subjects with borderline hypertension.
    • Autonomic dysfunction may play a role in altered salivary function in hypertension.
    • Further research into the neuro-glandular axis in hypertension is warranted.
