Zusammenfassung:Background The nose can be damaged by environmental pollutants and foreign bodies, as well as a result of trauma, infection or surgical interventions. Proper healing of the damaged nasal mucosa is important for health. Objective There is no study in the literature investigating the effects of rosmarinic acid on mucosal healing. The aim of this study was to investigate the effect of rosmarinic acid on nasal mucosal healing. Methods 21 male, adult Spraque Dawley albino rats were divided into three groups as the control group, the local treatment group in which rosmarinic acid was applied locally to the nasal mucosa, and the systemic treatment group in which rosmarinic acid was injected intraperitoneally. The wound area was obtained by creating a trauma area by inserting a 10 mm interdental brush through the right nasal nostril into the right nasal cavities of all animals. For the following 15 days, the treatment agent was applied as indicated once a day and on the 15th day the animals were decapitated and tissue samples taken from the nasal mucosa were prepared for histopathological examination. The preparations were examined in terms of cellular hyperplasia, goblet cell hypertrophy and degeneration, leukocyte infiltration, cilia loss and degeneration, edema and vascular dilatation, and they have been classified into four categories as mild (+), moderate (++), severe (+++) and very severe (+++). Results There was a significant difference between the groups in terms of all parameters evaluated, and there is a decrease in the intensity of the parameters with transition from the control group to the local group and from there to the systemic group. Conclusion Systemic rosmarinic acid administration showed an enhancing effect on the healing of experimentally induced nasal mucosal injury due to its possible anti-inflammatory effect.
