摘要
Biopsy specimens of human jejunal mucosa were examined with the Stereoscan technique for the first time. With this method it was possible, also for the first time, to represent the three-dimensional structure of the mucosa surface at magnifications of up to x 10,000. In addition to constriction furrows manifested by the villi, a striking feature was the fact that the surface of the individual cells projects hemispherically, with the result that an increase in the absorption surface of at least 25% is achieved. Moreover, a line Modulation was detected, which we suppose to correspond to the microvilli. Variations in the fine structure of the cell surface between a normal mucosa and one showing slight changes in light microscopic examination, could not be determined. © 1969 S. Karger AG, Basel.
