Fibrin glue(FG) has been successfully used in a wide range of surgical fields such as
skin graft fixation, nerve repair, cartilage reattachment and microvascular anastomoses.
The sustained release of antibiotics from FG for a longer period is desirable to avoid
bacterial infection after application. Furthermore, this is indispensible for FG so as to be
used as a local antibiotic carrier. Ampicillin sodium(AMP-Na) was selected as a model
antibiotic and incorporated into FG. In an attempt to achieve sustained release of it, the
incorporation of AMP-Na into FG was tried in two different ways. One was
incorporation of AMP-Na in a dispersed state with the modification of the preparation
method of FG. The other was incorporation of bovine serum albumin
microspheres(BSA-MS) containing AMP-Na. The in vitro release of AMP-Na from
various FG was examined. The modifications of FG were found not to be appropriate
methods to achieve sustained release of AMP-Na. However, the incorporation of
crosslinked BSA-MS containing AMP-Na into FG was found to reduce the initial rapid
release of AMP-Na and retared the release of AMP-Na ; t0.9 was 33
hours.
The prophylactic efficacy of antibiotic-loaded FG against pathogenic bacteria was
evaluated by artificially induced abscess model in the rabbit. The abscess model in the
rabbit was induced by inoculation of pathogenic bacteria(synchronized culture of
Staphylococcus aureus). Three different experimental group of pathogenic bacteria was
injected into oral mucosa of the rabbit and hisopathological assessment was examined to
evaluated the prophylatic efficacy of antibiotic-loaded FG. In pathogen only group, large
pus pocket was formed after only 24 hours. However, the abscess diameter of the
combination group(i.e.,pathogen and AMP-Na loaded FG) showed much smaller than of
pathogen only group. Histopathological study also showed that there was the least
inflammatory cell in the combination group of pathogen and BSA-MS loaded FG among
the three experimental group tested. These results indicate that antibiotic-loaded FG has
not only the prophylactic efficacy against post-operative infection, but also has the
potential to be employed as a local biodegradable antibiotic carrier.
