Abstract:
To explore the prevention of deterioration of damaged tissue in gunshot wounds in limbs in hot and humid environment, 18 healthy male mongrel dogs were divided into three groups randomly: hot and humid environment (HHE) group, normal environment (NE) group, and heat acclimatization (HA) group. Histopathological changes and bacterial quantity in wound tracks were observed at postinjury o, 1, 4, 6, 8, 12 and 24h. It was found that the swelling of limbs and local pathological changes in injured tissues of HA group were significantly less serious and appeared later than those of HHE group, but severer and appeared earlier than those of NA group. The period that the bacterial quantity reaching the critical point of infection was 8h in HHE group, 12h in HA group and NE group. It is concluded that the pathological changes in gunshot injury in dogs inflicted in hot and humid environment could be lessened by exercise with heat acclimatization.
