[A comparative study on wound healing treated by different doses of bovine basic fibroblast growth factor (bFGF)].
OBJECTIVE
To explore the optimal dosage and method of bFGF application on surgical wound for accelerating its healing.


METHODS
Laceration wounds on the extremities of 73 patients were served as the target. The wounds were applied with three different doses of bFGF (75 Au/cm(2), 150 Au/cm(2), 300 Au/cm(2)) and with three application methods, i.e. once a day, three times a day and once a day with moistening. Normal saline with 0.5% metronidazol was employed as control agents. The wound healing time in every groups was recorded in days and compared with each other.


RESULTS
When compared to each other, the wound healing time (day) was much shorter (P < 0.05) with bFGF application in dose of 75 similar 300 Au/cm(2). There were also obvious differences in wound healing time among groups treated with the same dose but with different methods (P < 0.01). In addition, three times a day and once a day with moistening of bFGF application could further shorten the wound healing time.


CONCLUSIONS
Compared to the dosage of the agent, the frequency and method of bFGF application seemed more important for its optimal effects. In view of the convenience, feasibility and economy, once a day with moistening was recommended for clinical application.
