atophysiological changes in the capillary network of the skin have long served as a reference point in the diagnosis of many infectious diseases. Skin hemorrhages, petechial rashes, which also occur in some cases and in non-infectious diseases, prompted the scientific thought to study the biological changes in skin capillaries and to create artificial conditions under which it would be possible to get skin hemorrhages by stagnation or injury.
