A Scanning Electron Microscope Study of the Human Spleen

A scanning electron microscope study of the human spleen.

A surgically obtained spleen was perfused with saline and with a glutaraldehyde solution. After fixation the tissue blocks were treated with tannin-osmium impregnation technique and dehydrated. The blocks immersed in ethanol or isoamyl acetate were quench-frozen in liquid nitrogen and cracked to be observed in a field emission scanning electron microscope. 1. The sinus is lined by rod cells con...

the scanning electron microscope

it is only thirteen years since the scanning electron microscope has been available commercially. yet, even in this short period of time, this instrument has been a powerful tool in the investigation of topography, electrical and magnetic properties, crystal structure, cathodoluminescent characteristics etc. of solid specimens. today, this type of microscope has opened its place alongside the c...

Dental Wear: A Scanning Electron Microscope Study

Dental wear can be differentiated into different types on the basis of morphological and etiological factors. The present research was carried out on twelve extracted human teeth with dental wear (three teeth showing each type of wear: erosion, attrition, abrasion, and abfraction) studied by scanning electron microscopy (SEM). The study aimed, through analysis of the macro- and micromorphologic...

A Scanning Electron Microscope Study of the Lactating Mammary Gland

The study of internal soft tissue with the scanning electron microscope poses special technical problems of fixation, cleaning, and dehydration (3, 4, 6, 7) . For the dried, prepared tissue to be biologically significant, the surface configurations and interrelationships of its constituent cells must be preserved in a state similar to the way they appear in life . At the same time, the tissue s...
