Over the past year there have continued to be advances in our understanding of the functions of the nasal mucosa and mucociliary system. In the area of mucosal blood flow, the roles of several peptide neurotransmitters in the regulation of mucosal circulation have been clarified. Ciliary function has been studied leading to a better understanding of the effects of classical and peptide neurotransmitters and prostaglandins on ciliary beating. The possible role of bacterial products on ciliary function has been explored as it relates to the etiology and progression of clinical sinusitis. Finally, the mechanisms controlling the processes of glandular secretion and transudation have been examined in relation to allergic and nonallergic rhinitis.
