Morphological characteristics of monosodium urate: a transmission electron microscopic study of intact natural and synthetic crystals.
Transmission electron microscopic studies of synthetic and natural monosodium urate crystals dried on formvar coated grids showed identical internal structures in all crystals. At higher magnification the crystals' surface showed angular or wavy irregularities, and more rarely some crystals appeared to have other tiny crystals on the surface. Protein-like surface coating was not observed except...
متن کاملEosinophilic leukaemia: morphological, cytochemical, and electron microscopic studies.
The eosinophils of a patient with eosinophilic leukaemia were studied with 13 different cytochemical methods using light and electron microscopy. Apart from the 'left shift' of the eosinophils in bone marrow and peripheral blood, the following morphological changes were noted: uncoordinated maturation of the nucleus and cytoplasm, changes in size of the specific granules, and hypogranulation to...
متن کاملElectron microscopic observations on platelet aggregation induced by cationized ferritin.
Washed and gel-filtered human platelets were dose-dependently aggregated by the addition of cationized ferritin (CF). Ca++ and plasma factors were not necessary to induce the aggregation. Immediately after the addition of CF, CF particles were attached to the surface of platelets that showed discoid form, as observed electron microscopically. Some platelets were connected to each other through ...
متن کاملScanning electron microscopic characteristics of phakic intraocular lenses.
OBJECTIVE To analyze the surface quality of new generation phakic intraocular lenses (IOLs). DESIGN Experimental materials study. MATERIALS Three different new generation phakic IOLs: angle-fixated anterior chamber lens Chiron Vision NuVita MA20 (polymethylmethacrylate [PMMAD, iris-fixated anterior chamber lens Ophtec Artisan Iris-Claw (PMMA), posterior chamber lens Staar ICM (polymer from ...
متن کاملHorner's syndrome: an electron microscopic study of a human iris.
Electron microscopy was performed on the irides of a man with a history of a long standing Horner's syndrome which resulted in iris heterochromia. Comparison of his normal brown iris with the depigmented blue iris showed depletion of anterior border cells and absence of sympathetic nerve fibres. Stromal melanocyte numbers were also diminished but melanosome numbers within the residual cells wer...
