The mechanisms that regulate mucin release in chronic otitis media with effusion, a leading cause of hearing loss in children, remain largely unknown. We developed an animal model using Sprague-Dawley rats to determine the factors responsible for muc

To determine whether the bacterial toxins associated with otitis media could induce morphologic changes in the organ of Corti, we inoculated the middle-ear cavities of healthy guinea pigs with either Streptococcus pneumoniae or sterile saline and the

To investigate the possible relationship between allergy and otitis media with effusion (OME), we investigated the hypothesis that allergen presentation to the middle ear causes functional disruption of the eustachian tube predisposing to the develop

This study was designed to investigate the presence of nitric oxide in human squamous cell carcinoma of the head and neck. We localized the activity of nitric oxide synthase in these tumors through immunohistochemical analysis using antibodies to L-c

Nitric oxide is known to function as a neurotransmitter in the central nervous system. It is also known to be involved in the central nervous system excitatory amino acid neurotransmission cascade. Activation of excitatory amino acid receptors causes

This study was designed to investigate the regulatory mechanisms of the mucosal microvascular network in the upper respiratory tract. Tracheal mucosal circulation was observed using a specially constructed chamber that allowed direct microscopic visu

Gentamicin is an extremely effective antibiotic against a wide variety of organisms. However, its use is limited by its nephrotoxic and ototoxic effects. Recent studies in rats have shown that poly-l-aspartic acid (PAA) effectively blocks the nephrot

Cochlear blood flow has been shown to be controlled, in part, by the sympathetic nervous system. We have used immunocytochemical staining for tyrosine hydroxylase (TH) to further demonstrate the extent of catecholaminergic innervation of the cochlea.
