Abstract:
Objective To establish animal models in order to provide an experimental study basis for both the pathogenesis study and taking effective prevention scheme for doxorubicin extravasation injury. Methods A total of 20 Kunming mice for experiments on doxorubicin extravasation injury were divided in-to four groups, I.e., high dose group(2 g/L), medium dose group(1 g/L), low dose group(0.5 g/L) and the control group (injection with water). Dosages were administered with subcutaneous injection on both sides of mice abdomen. The adverse reaction of body, damage areas of extravasation injury, recovery period were observed and histopathologic slides of animal models on both 4 days and 11 days after experiment were performed and compared. Results No significant adverse body reaction was observed after injection for all groups. The damage areas due to extravasation injury were dosage and concentration dependent. In addi-tion, significant differences in recovery period were observed for mice in different groups, that is, the higher injection concentration and dose led to the longer recovery period. Results from the histopathologic study in-dicated that the putrescence of damage area was developed in high dose group mice, and the ulcer occurred after 4 d of dosage in medium dose group mice, respectively. In contrast, no ulcer was observed in low dose group mice. Conclusions It would be feasible to establish a prevention model for mice on doxorubicin extravasation injury by subcutaneous injection at a dosage of 0.05ml(1 g/L).
