    Notes: Summary Cardiac thrombosis due to atrial fibrillation (AF) has been recognized as the most common cause of cerebral embolism. However, sometimes no macroscopic thrombus is found at autopsy in the heart of a victim of this type of cerebral embolism. We investigated morphological changes in the left atrial endocardium of 31 patients (including 21 cases with AF) who had died of cerebral embolism. “Rough endocardium” (RE) seen macroscopically provided evidence for the existence of atrial thrombosis. The RE that appeared in AF cases was due to a granular and wrinkled appearance of the endocardium associated with oedematous and fibrous thickening. Fibrin-thread deposits were also always distinguishable. Mural thrombi and oedema with neutrophil infiltration in the subendocardium could be seen under the microscope. Small areas of endothelial denudation and thrombotic aggregations were commonly observed by scanning electron microscopy (SEM). These SEM lesions were significantly more frequent in cases with AF than in controls (P〈 0.001). The diagnostic success rate for atrial thrombosis among cases with AF increased from 33.3% to 81% when thrombi proven by histological investigation of the areas with RE were added. Left atrial RE may be an anatomically relevant finding for the existence of atrial thrombosis with AF, when the thrombosis cannot be detected upon gross observation at autopsy.

    Apoptosis related antigen, LeY and nick-end labeling are positive in spinal motor neurons in amyotrophic lateral sclerosis (1994)

    Notes: Abstract Expression of LeY, a difucosylated type 2 chain determinant, has been previously identified as a characteristic of cells undergoing apoptosis. Immunohistochemistry using an antibody for LeY, as well as nick-end labeling for the detection of DNA breaks, was done on cervical spinal cord sections from ten patients with amyotrophic lateral sclerosis (ALS) and nine patients who had died from other causes. LeY-positive immunoreactivity was seen in the motor neurons of seven ALS cases, but in none of the other cases. Nick-end labeling was also positive in four ALS cases. Double staining of motor neurons by anti-LeY antibody and nick-end labeling was shwon in these cases. Other LeY-positive structures, such as reactive astrocytes and fat-laden microglia/macrophages in the lateral and anterior columns, were negative for nick-end labeling. These results suggest that the mechanism of cell death in the spinal motor neurons of ALS may be apoptosis.
