RESUMO
Purpose of the study the peculiarities of rearrangements of skeletal muscle fibroblasts surrounding the wound canal at various times after an experimentally modeled gunshot shrapnel wounds. Experimental modeling of gunshot shrapnel wounds of soft tissues has been carried out on 20 laboratory animals - breeding rabbits of the breed «Chinchilla¼. To laboratory animal was caused a gunshot wound in the sartorius area with the gun «Fort-12¼ caliber 9 mm. The initial velocity of the fragment was 305 m/s. Ultrathin muscle sections were examined using an EM-125 electron microscope at accelerating voltage of 75 kV, with a magnification of 20000 - 60000 arm. In an experiment it was revealed that on the thirtieth day most of the fibroblasts of the wound canal in the femoral muscle tissue had an ultrastructure characteristic of the course of compensatory-adaptive, synthetic, and reparative processes. Sixty days after a gunshot wound, the submicroscopic organization of fibroblasts from the wound canal area undergoes disorders associated with a decrease in the synthetic activity of fibroblasts.
