Abstract
Introduction: There has been an increasing trend in spinal surgery interventions in recent years. Low back pain is a disorder that is seen at least once in the lifetime of approximately 80% of the general population. Today, neurosurgeons perform operations including laminectomy for various reasons. Epidural fibrosis is a scar tissue that develops after posterior spinal surgery. Various synthetic and organic materials have been used in experimental studies to prevent epidural fibrosis in laminectomy defects. In this study we aimed to investigate and observe histopathologically the effectiveness of cyclooxygenase inhibitor drugs; tenoxicam and diclofenac sodium in the experimental rat laminectomy model in preventing the postoperative spinal epidural fibrosis.
Material and methods: In this study, 32 Wistar-Albino female rats were used. 8 mg/kg tenoxicam and 1.5 mg/kg diclofenac sodium were applied on the dura with an absorbable gelatin sponge. After decapitation, L1-L4 laminectomy area was totally removed and histopathological examination was performed.
Results and conclusions: It has been shown that the topical application of diclofenac sodium and tenoxicam, which are selective Cox inhibitor drugs, prevents fibroblast migration by forming a local barrier and Cox inhibitors are caused by the inhibition of prostanoids, which are inflammatory mediators.
期刊介绍:
Folia Neuropathologica is an official journal of the Mossakowski Medical Research Centre Polish Academy of Sciences and the Polish Association of Neuropathologists. The journal publishes original articles and reviews that deal with all aspects of clinical and experimental neuropathology and related fields of neuroscience research. The scope of journal includes surgical and experimental pathomorphology, ultrastructure, immunohistochemistry, biochemistry and molecular biology of the nervous tissue. Papers on surgical neuropathology and neuroimaging are also welcome. The reports in other fields relevant to the understanding of human neuropathology might be considered.
