Abstract:
Objective To study the effects of systemic irradiation and conglutinant drug W11-a12 on the number and some functions of wound nentrophils (Neu). Methods Wound Neu was collected from sponges which were implanted in rat's dorsum incision. The number of Neu, as well as the phagocytic function and motility of wound Neu were measured. Results After 4,6,8 Gy systemic irradiation, the number of white blood cells and Neu in wound, as well as the phagocytic function and chemotactic motility of wound Neu, were significantly decreased at 24 h, 48 h after wounding. W11-a12 markedly increased the number of wound Neu, improved the phagocytic function and chemotactic motility of wound Neu at 24 h, 48 h after wounding despite the rats were radiated or not. Conclusion The results indicated that the decreased number and function of wound Neu in the early stage of wound healing contributed to the impairment of repair after systemic irradiation. W11-a12 accelerated normal and irradiation-impaired wound healing partly by increasing the number of wound Neu and improving the Neu function.
