  1. 16. PACAP and airway regulation with special reference to smooth muscle and neutrophils

    Författare :Johan Kinhult; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen; Otorhinolaryngology; allergy; neutrophils; smooth muscle; PACAP; airway regulation;

    Sammanfattning : The investigations focus on the neuropeptidepituitary adenylate cyclase-activating peptide and its effects on airway regulation, with emphasis on smooth muscle relaxation and neutrophil activation and migration. In the nasal mucosa, PACAP-containing nerve fibers were localized invascular smooth muscle and close to seromucous glands. LÄS MER

  3. 17. Influence of middle ear pressure changes on labyrinthine hydrodynamics and hearing physiology

    Författare :Konrad Konradsson; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; audiology; Pressure; Audiometry; Cats; Animal; Cochlea; Cochlear aqueduct; Ear; Eustachian tube; Hearing; Otorinolaryngologi; Human; Labyrinth; Otorhinolaryngology; Meniere s disease; audiologi; hörsel- och talorganen;

    Sammanfattning : Results from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. LÄS MER

  4. 18. Imbalance and fractures in the elderly Effects of decreased vibration sensation and vestibular asymmetry

    Författare :Ella Kolbrun Kristinsdottir; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rehabilitation; Rehabilitering medicinsk och social ; Postural Control; Elderly; Vibration sensation; Vestibular asymmetry; Falls; Fractures.; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Otorhinolaryngology; audiology; auditive system and speech; revalidation; kinesitherapy; Physical medicine; hörsel- och talorganen; audiologi; Otorinolaryngologi;

    Sammanfattning : Control of the upright stance and locomotion is a complicated process of muscular activity. The muscular activity is dependant on afferent information from the different sensory organs and interpretation in the central nervous system. Age-related degenerative changes exist in all the domains concerned with control of posture. LÄS MER

  5. 19. Oral Motor Function, Voice, Speech and Language in Children with Tonsillar Hypertrophy in Relation to Surgical Outcome

    Författare :Inger Lundeborg Hammarström; Anita McAllister; Elisabeth Hultcrantz; Anneli Yliherva; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; Otorhinolaryngologi;

    Sammanfattning : The aim of this thesis was two-fold: first, to evaluate four different functional aspects of the speech and language spectrum; oral-motor function, voice, /s/-articulation and phonology in preschool children with tonsillar hypertrophy before and after surgical treatment. The second aim was to investigate weather the outcome of surgery was equal for two surgical techniques; tonsillectomy or tonsillotomy combined with adenoidectomy when necessary. LÄS MER

  7. 20. The Round Window Membrane - Gateway to the Cochlea : A Morphological and Electrophysiological study

    Författare :Leif Nordang; Sten Hellström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; round window membrane; pseudomonas exotoxin; auditory brainstem response; hearing loss; endolymphatic sac; inner ear immunology; glutamate; nitric oxide inhibitor; glucocorticoid.; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Topical treatment of several inner ear diseases through the round window membrane (RWM) might be feasible in the near future. Bacteria toxins, ototoxic drugs and noise trauma seem to harm the inner ear by a common pathway which involves, excessive outflow of the afferent neurotransmitter glutamate and formation of nitric oxide (NO), which can severely damage cells/nerve endings and lead to cell death.
