The effect of centrally administered erythropoietin on cardiovascular and respiratory system of anaesthetized rats

In conclusion, our findings showed that centrally injected erythropoietin caused pressor and tachycardic response, an increase in respiratory frequency and volume in anaesthetized rats. Moreover intravenous injection of the highest dose of EPO used in the study caused no effect suggesting a central mechanism of action for the agent. Hence, one can hypothesize that erythropoietin may play a role in the central regulation of cardiovascular and respiratory system as a neuromodulator or neuromediator.
