Abstract:
OBJECTIVE:To study the distribution and proportion of neuropeptide containing nervers in the sinus node in cases of sudden manhood death syndrome (SMDS) and to explore the mechanism of SMDS.
METHODS:Immunohistochemical staining and quantitative analysis of neuropeptide Y (NPY) and vasoactive intestinal peptide(VIP) in the sinus node in 6 cases of SMDS and in 12 cases of non-cardiac death(control group) were achieved by LSAB method and computerized image system.
RESULTS:As for NPY positive materials, VIP positive materials and the ratio of VIP/NPY in the sinus nodes, there were no significant difference between the control group and SMDS group.
CONCLUSION:The mechanism of SMDS and the abnormality of autonomic nervous innervation in the sinoatrial nodes maybe incorrelation.
