CHARACTERISTICS OF SOFT TISSUE WOUNDS CAUSED BY BULLETS FROM INFANTRY GUNS ON EXPERIMENTAL ANIMALS

Abstract

Objectives: To describe some characteristics of soft tissue wounds caused by bullets from infantry guns on experimental animals. Methods: A descriptive study on the characteristics of macroscopic lesions of soft tissue wounds caused by bullets from infantry guns on experimental animals. Shooting on each pig corresponds to a type of ammunition, including 5.56 x 45mm bullet, 7.62 x 39mm bullet, and 9 x 19mm bullets to create wounds in the chest area, liver area, abdomen, and buttock area, then those lesions were examined. Results: All wounds had entry wounds with a size smaller than the size of the corresponding bullet. Most entry wounds were round (range of 65% - 75%), while others were oval in shape. Bullets 9 x 19mm caused the most graze wounds (45%). Bullets with high damage energy and velocity caused larger outlet damage and were larger than the corresponding bullet size. The exit wounds caused by 7.62 x 39mm bullets and 5.56 x 45mm bullets were mainly in oval shape (80% and 85%, respectively); the rest were star-shaped. Exit wounds from the 9 x 19mm bullet were mostly oval in shape (92.5%). The shape of the 7.62 x 39mm and 5.56 x 45mm bullet-related permanent cavities had an angular, jagged form, the 9 x 19mm bullet permanent cavities were mostly straight, with little angle. Conclusion: All entry wounds had a smaller size than that of the corresponding bullet, most of which were round. The bullets with high velocity and energy damage caused larger damage and larger than the corresponding bullet size, mostly oval in shape, the rest were star-shaped. The shape of the 7.62 x 39mm and 5.56 x 45mm bullet permanent cavities had an angular, jagged form, the 9 x 19mm bullet permanent cavity was mostly straight, with little angle.
