1. 1. Morphology and biochemistry of the tympanic membrane in relation to retraction pathology

   Författare :Johan Knutsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Tympanic membrane; retraction pathology; secretory otitis media; cholesteatoma; pars tensa; lamina propria; keratinizing epithelium; collagen type; progenitor cells; stem cells; immunohistochemistry; electron microscopy;

   Sammanfattning : Otitis media is very common during childhood and may predispose for tympanic membrane (TM) pathology later in life. Therefore, it is important to investigate the possible changes in TMs subjected to otitis media. There is evidence of a relationship between previous otitis media and TM retraction disease. LÄS MER

3. 2. Middle ear structure in relation to function : the rat in middle ear research

   Författare :Nils Albiin; Umeå universitet; []
   Nyckelord :rats; Eustachian tube; ear; middle; tympanic membrane; palatal muscles; mucous membrane; blood vessels; mast cells; otitis media; microscopy; electron;

   Sammanfattning : The present study was undertaken to evaluate the rat as a model for middle ear re­search. The rat was chosen primarily because the gross structure of its middle ear shows several similarities to that of man. LÄS MER

4. 3. Topical anesthesia of the tympanic membrane : an experimental animal study

   Författare :Sten-Hermann Schmidt; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Topical anesthesia; middle ear; tympanic membrane; cochlea; collagen fibres; lidocaine; 96 % phenol; Bonain s liquid; auditory brainstem response; ototoxicity; cytocochleogram; scanning electron microscopy; rat; guinea pig;

   Sammanfattning : Myringotomy plays an important role in otological therapy. The procedure requires an efficient anesthesia, which can be obtained without general anesthesia. However, the use of local anesthetics on the tympanic membrane (TM) has been abandoned in many places, as general anesthesia has been readily available. LÄS MER

5. 4. Middle ear cholesteatoma : Surgical outcome and aspects of the innate immunity

   Författare :Johanna Westerberg; Elina Mäki-Torkko; Henrik Harder; Anna Granath; Juha Silvola; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Cholesteatomas are bone destructive expansions of keratinizing squamous epithelium in the middle ear and temporal bone. Today, surgery is the only treatment. There are several controversies regarding cholesteatomas, including the definition, the pathogenesis and the surgical method. LÄS MER

7. 5. Plasminogen : a novel inflammatory regulator that promotes wound healing

   Författare :Yue Shen; Tor Ny; Gunilla Høyer-Hansen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Plasminogen; inflammation; wound healing; diabetic wounds; tympanic membrane perforations; medicinsk biokemi; Medical Biochemistry;

   Sammanfattning : The plasminogen activator (PA) system has been shown to be intimately involved in wound healing. However, the role of this system in the initiation and resolution of inflammation during healing process remained to be determined. LÄS MER
