[Important aspects of nasal bleeding pathogenesis].

The review is dedicated to an important multidiscipline problem, nasal bleeding (NB). The presented analysis of Russian and foreign literature on the most important aspects of the problem shows the variety and complexity of the leading pathogenetic mechanisms of NB (the condition of hemostatic and lipid peroxidation systems, the activity of biologically active substances and the kinine system, the condition of local and system blood flow), contradictoriness of data on some aspects, and insufficient knowledge of a range of aspects. The collected data on the pathogenetic mechanisms of NB, despite the high quality of some studies, do not suggest the existence of a common modern theoretical base on this problem.
