Abstract:
500 m/s,6 dogs),"Middle" (1,000 m/s,8 dogs) and "Low" (700 m/s,7 dogs).De-bridement and gross examination were carried"out 6 hours after injury.The main conclusions were as follows: 1.Grossly,most of the wound tracks were blind.The primary wound track in the "High" velocity group looked like a funnel in shape.The wound cavity near the entrance was the largest in diameter.2.The severity of the tissue damage depended on the impact velocity.The higher the velocity,the larger the wound cavity,the more were the debrided damaged tissues,and the wider was the area of tissue damage around the cavity.3.Based on the gross inspection,and light and electron microscope observations it was found that one of the predominant characteristics of tissue damage caused by fragments was the irregularity or unevenness.It was especially true in the case of the "High" velocity group.The distribution of tissue damage seemed to be "Jumping" or "Mosaic".It probably resulted from the irregularity of energy delivery from fragments of high velocity and light mass.4.The difference in morphological characteristics between wound tracks by bullets and those by fragments was pointed out and its causes discussed.
