[Evaluation of the anti-ulcer drugs using image analysis technology: effect of aldioxa containing preparation on the experimental gastric ulcer in rats].

Direct measurements under a microscope have been employed to evaluate experimental gastric ulcers, but the following problems have been left unsettled: it takes too much time, and much experience is required to perform accurate, objective measurements. The present study demonstrates the usefulness of image analysis technology for evaluating anti-ulcer drugs. With this newly developed method, the region of gastric mucosal injury can be automatically and/or mechanically chosen on the basis of three different factors: intensity, hue and purity.
