[Morpho-functional changes in tissues surrounding a gunshot wound]

The authors studied the dynamics of changes of microcirculatory disorders in tissues surrounding the wound canal in experimental animals with gunshot injuries of the soft tissues of the thigh. Tissue radiometry and scanning were used. The damage was found to be regularly distributed in 4 zones of microcirculatory disorders differing also in morphological characteristics on a light and electron level: zone 1 of primary necrosis or traumatic destruction of tissues; zone 2 of secondary necrosis (forms on the 3rd day after the injury); zone 3 of reactive-destructive changes of tissues, which is the source of granulation tissue development (microcirculation in this zone is restored by the end of the 2nd week after the injury); zone 4 of reactive changes in the tissues with complete abatement of microcirculatory disorders by the end of the 1st week after the injury. The obtained data possess theoretical and practical significance.
