  • Methods and compositions for treating gastroparesis
    Patent number: 7208159
    Abstract: Compositions comprising a plurality of yeast cells, wherein said plurality of yeast cells are characterized by their ability to treat gastroparesis in a subject (e.g., stimulating stomach contraction, reducing abnormal gastric acid and/or pepsin production), as a result of having been cultured in the presence of an alternating electric field having a specific frequency and a specific field strength. Also included are methods of making and using such compositions.
