Abstract:
Objective To investigate the changes of actin (HHF35), serum albumin (A1), fibronectin (Fn) in cardiac cells and cardiac conducting sysytem (CCS) in order to probe into postmortem diagnosis of sudden manhood death syndrome (SMDS). Methods Immunohistochemical detections of actin, serum albumin and fibronectin (Fn) in the cardiac cells and CCS were performed by S-P method in cases with SMDS and cases died from coronary heart disease and non-cardiovascular diseases which were used as the control. Results Of the 22 cases with SMDS, 17 were found of actin-negative staining, 18 serum albumin-positive and 15 Fn-positive staining with evident pathological lesions in CCS in 8 cases. Conclusion It is suggested that SMDS is associated with early myocardial ischemia or infarction, which results in abnormality in actin, serum albumin and fibronectin (Fn) in the cardiac cells and CCS.
