[State of the microcirculation in periarteritis nodosa based on morphological and biomicroscopic data].

The status of microcirculation in periarteritis nodosa was studied by impregnation method (serous membranes) and biomicroscopy (eyeball conjunctiva). Pathological and adaptative changes in terminal vessels were found. It is suggested that the involvement of microcirculation ways in this disease is systemic and that morphological changes in microvessels are comparable to biomicroscopic changes.
