[The mechanisms of antioxidantenzyme against inflammatory lesion in animal oral mucosa. I. An investigation on microcirculation in oral mucosa].

A technique of vital microcirculation observation and electron microscope were used to study the microcirculation in hamster cheek pouch, in which an acute inflammatory lesion was induced by oxygen free radicals (OFR). At the same time, the effect of superoxide dismutase (SOD) on the microcirculation was assessed. The results showed that in the model group the microcirculation disturbance in the cheek pouch was very serious. However, in the SOD group the microcirculation was almost unchangable.
