Abstract:
Objective To study distribution of the calcitonin gene-related peptide-immunoreactive fibers in the cremaster arteries of the rat.Methods The distribution of the calcitonin gene-related peptide-immunoreactive fibers in the cremaster arteries had been studied by means of ABC technique.Results The calcitonin gene-related peptide-immunoreactive fibers were observed on all branches of cremaster arteries.The immunoreative fibers in first and second branches of the arteries exhibited the denser grains and denser mass,but in third branches,the network of the fibers was obvious.The density of the immunoreactive fibers reduced following the bifurcations of the arteries.The network of the fibers also could be found in the capillary.Conclusion The results demonstrated that the distribution of calcitonin gene-related peptide immunoreactive fibers might be related to the physiological regulation and microcirculation of the cremaster arteries.It formed the morphological basis for experimental model of researching nerve regulation in the microcirculation.
