1. On optical methods for intracerebral measurements during stereotactic and functional neurosurgery : Experimental studies
Sammanfattning : Radio frequency (RF) lesioning and deep brain stimulation (DBS) are the two prevailing surgical treatments for movement disorders within the field of stereotactic and functional neurosurgery. For RF-lesioning, a small volume of brain tissue is coagulated and knowledge of the lesion size and growth is of great importance for the safety and outcome of the procedure. LÄS MER
2. Topical anesthesia of the tympanic membrane : an experimental animal study
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
3. The Immune Response to One-Lung Ventilation : Clinical and Experimental Studies
Sammanfattning : One-lung ventilation (OLV) as an established procedure during thoracic surgery may be injurious in terms of increased mechanical stress characterised by alveolar cell stretch and overdistension, increased cyclic tidal recruitment of alveolar units, compression of alveolar vessels and increased pulmonary vascular resistance. This may result in ventilation-induced lung injury with pro-inflammatory cytokine production, leukocyte recruitment and neutrophil-dependent tissue destruction. LÄS MER
4. Experimental Helicobacter pylori infection in an animal model
Sammanfattning : Background: Helicobacter pylori is a microaerophilic Gram-negative bacterium colonizing the human stomach. The prevalence of this infection is between 20-90% depending on geographic location. Comprehensive studies have shown significant relationships between H. pylori infection and chronic gastritis, peptic ulcer and gastric carcinoma. LÄS MER
5. Experimental porcine models of retinal ischemia
Sammanfattning : Retinal ischaemia resulting from e.g. diabetes, vein thrombosis or arterial occlusion, is one of the major causes of visual impairment and blindness. Although new methods of treatment are being developed, there is still a need for more effective pharmacological forms of treatment. LÄS MER
