[Laboratory animal models to test the efficacy of geriatrics (author's transl)]

The main effect of drugs called geriatrics should be improvement of brain functioning in the aged. Testing chemical substances in laboratory animals is a necessary prerequisite in the development of new drugs. These findings are becoming especially useful when they are interpreted in terms of a valid model. It is believed that hypoxia is often the cause of diminished brain function in the aged. Taking hypoxia as an example it is attempted to find a basis for establishing an animal model which could serve to test geriatrics.
