An electron microscope study of X-ray produced giant Hela cells is described. The results extend earlier light microscope observations to the sub- microscopic region where clear differences from normal structures are apparent. Of particular interest are intranuclear inclusions, nucleolar fragments, membrane ...

During gross anatomy dissections of the brain, a developmental abnormality of the septum pellucidum was found in a 31-year-old male cadaver. Other parts of the central nervous system in this cadaver were normal in every aspect. Histological samples were taken from the neighboring areas of this abnormality, and they were examined under light ...

A technique for the preparation of o mium-fixed ultrathinsectioned frog blood cells for examination in the electron microscope is described. Erythrocytes exposed to 1000 rads x radiation were swollen in appearance and had abnormal bulging nuclei. Mitochondria were demonstrated in frog erythrocytes, and exposure to 1000 rads ...
A case of glycolipid lipoidosis (Fabry's disease) in a 27-year-old man is recorded. The case is unusual in that despite extensive disease evidenced by widespread skin lesions, ocular abnormalities, and proteinuria, renal function was only minimally impaired. Electron microscope studies of kidney and skin showed that most cells ...

Electron microscopic findings from a case of anterior subcapsular cataract are presented. It is suggested that the epithelial cells increase in activity, form fibrillae and multiple layers of basement membrane, and these make up the anterior plaque. The same activity, to a lesser degree, is present under the posterior capsule. This ...

Three spontaneously aborted fetuses with Type I achondrogenesis in a family with a first cousin marriage are described. Studies by light microscopy revealed abnormal cartilage, enchondral, and periosteal bone, and normal tooth development with abnormal alveolar bone. Electron microscopic studies of cultured skin ...
We report a case of Alexander's disease in a black South African boy of 9 years. The child presented with a grossly abnormal stooped posture, generalised weakness, and slurred nasal speech. Computerised tomography revealed diffuse low radio-density confined to the white matter, and enlarged ventricles. Cerebral biopsy confirmed the diagnosis. The histopathological and ...
