Abstract

Abstract : Atlantoaxial disorders are often correlated with hypertension in practice. In order to study the relationship between atlantoaxial disorder and hypertension, we attempted to construct an animal model. In this work, we presented an animal model where their atlantoaxial joints were misaligned. We investigated the changes of blood pressure before and after treatments of the modeled rats. We had the following results. (1) SBP and DBP of each surgery group were significantly higher than those of control and sham groups. (2) After the second operation (the fixture was removed), SBP and DBP of both surgery groups decreased and got closer to the control and sham groups after 7 days. (3) Heart rates got significantly higher in both surgery groups, compared to control and sham groups. (4) The blood Ach levels of the surgery groups were significantly lower than those of control and sham groups. With these results, we concluded that we successfully constructed cervical atlantoaxial disorder models in rats that showed hypertension symptom. However, the underlying mechanism connecting atlantoaxial disorder and hypertension still requires further study.
