ABSTRACT
Introduction: Diseases associated with the Central Nervous System represent a group of conditions with important social and economic repercussions. New treatment strategies with NeuroEPO offer new opportunities to prevent the onset and progression of these disorders. NeuroEPO administered intranasally can reach the Central Nervous System through various mechanisms involving the olfactory and trigeminal nerves, respiratory and olfactory mucosa, nasal vasculature, cerebrospinal fluid, and the lymphatic system.Objective: To determine the effect of intranasal administration of NeuroEPO on the histologic structure of the respiratory mucosa and its associated lymphatic tissue in Wistar rats.
Material and Methods: An experimental, descriptive, longitudinal, prospective study was conducted, using the Wistar rat as a biological model. Ten healthy animals were randomly distributed in two groups of five animals each. One of the groups received intranasal NeuroEPO for 28 days at doses of 300 μg/kg. The other group was given a vehicle at a rate of 0,3μl/g. The histological characteristics of the respiratory mucosa were studied. The Mann-Whitney test was used to compare the means.
Results: No alterations in the histological characteristics of the respiratory mucosa and the lymphatic tissue associated with the nasal mucosa were observed in Wistar rats after the administration of NeuroEPO.
Conclusion: Intranasal administration of NeuroEPO does not cause pathological changes in the histological structure of the respiratory mucosa or the lymphatic tissue associated with the nasal mucosa of Wistar rats in our experimental conditions.
