Abstract:
ObjectiveTo study the influence of Jiuqiang Naoliqing (JNQ) on the expression of calcitonin gene related peptide(CGRP)and Synapsin Ⅰ in brain of the spontaneous hypertension rats (SHR). MethodsThe rats were randomly divided into 4 groups: Wistar group, SHR group, lower dose of JNQ treated SHR group and higher dose of JNQ treated SHR group. The expression of CGRP and Synapsin Ⅰ in the dentate gyrus, CA1 subfield of hippocampus and cortex were determined by immunohistochemistry after treatment for 3 weeks. ResultsCompared with the Wistar group, the expression of CGRP and Synapsin Ⅰ in the dentate gyrus, CA1 subfield of hippocampus and cortex of SHR group significantly decreased. The treatment with lower dose of JNQ significantly enhanced the expression of CGRP in cortex(P<0.05 vs SHR).The treatment with higher dose of JNQ significantly enhanced not only the expression of CGRP in the dentate gyrus, CA1 subfield of hippocampus and cortex, but also that of Synapsin Ⅰ in the CA1 subfield of hippocampus selectively in comparison with SHR group. ConclusionJNQ may improve the micro circulation in brain by up regulating the expression of CGRP and enhance the modulating function of central nervous system by up regulating the expression of Synapsin Ⅰ in spontaneous hypertension rats.
