Electron microscopic x-ray microanalysis of normal and leukemic human lymphocytes.

Identification of thorium dioxide in human liver cells by electron microscopic x-ray microanalysis.

Thirty-two years after injection of thorium dioxide (Thorotrast) for diagnostic x-ray studies in a female patient deposits were found by light microscopy in the liver macrophages (Kupffer cells). They were shown by electron microscopy to be located inside secondary lysosomes, and by autoradiography and x-ray microanalysis they were identified as thorium.

Characterization of atmospheric particles by electron probe X-ray microanalysis.

Microchemical glass standards were used to validate a quantitation method based on peak-to-background (P/B) ratios from electron probe x-ray microanalysis spectra. This standardless method was applied to the determination of concentrations of individual particles from Malpha or Lalpha lines, as well as from Kalpha lines. The algorithm was tested on particulate glass samples for diameters rangin...

Electron Microscopy and X-ray Scanning Microanalysis of Needle Biopsy Material from Human Liver

A study has been made of the fine structure of hepatic parenchymal cells of human biopsy material in a case of pancreatic tumor with obstructive jaundice. Dense particles about 60 A in diameter have been found in the cytoplasm, which are considered to be ferritin molecules by electron microscopy. They are encountered throughout the cytoplasmic matrix and are often aggregated in electron-transpa...

Electron Microscopic Study and X-ray Probe Microanalysis of the Liver of LEC Rat, an Animal Model of Wilson Disease

Morphological identification of lysosomes was established by acid phosphatase reaction [1]. Pericanalicular lysosomes exhibited lead deposits after incubating liver slices with a lead and phosphate solution under acidic condition. Transitional elements, copper and iron, are stored in lysosomes as detoxified forms of cuprothioneins and hemosiderins, respectively. Genetic background of adult-onse...
