  • Title: [An experimental study of pathomorphologic characteristics and changes in energy metabolism of wound track on maxillofacial region of dogs].

    Journal: Zhonghua Kou Qiang Yi Xue Za Zhi; 1991 Nov; 26(6):351-3, 390. PubMed ID: 1820243.
    Abstract:
    The maxillofacial soft tissue wounds of dogs were inflicted by the spherical steel bullet with primary velocity 1.3 km/sec, 0.7 gm in weight. The pathomorphologic characteristics at 0-0.8, 0.8-1.6 and 1.6-2.4 cm from the wounding tracts were observed with light microscopy, and the amount of high energy phosphates (ATP) in the muscle samples was determined. The experimental results indicated that the contusion zone of skin and mucous membrane was 0.1-0.2 cm. and that of muscle was 0.5-0.8 cm the easily debridement is useful for the recovery of metabolism function. As they were wounded by the same velocity missiles, the soft tissue contusion zone of maxillofacial region was smaller than that of extremities.
