Outline of Final Research Achievements

Both non-noxious stimulation and repeated restrain stress effect to last the reduction of mechanical withdrawal threshold in the nucleus polposus applied rats model. The stress markers did not change according to the non-noxious stimulation, while the repeated restrain stress influence the delayed cytokain expression and histological nerve tissue changes. These results might suggest that the relationship between the pain-related behavior and nerve recovery. Stress is one of the triggers for chronicity of pain and furthermore studies are needed to investigate an influence on nerve tissue and it’s an important proof for treatment strategy.
