Mobile proliferation was measured by [3H]thymidine incorporation, hyperplasia was determined by mild microscopy and formation website of microvilli by scanning electron microscopy. The labelling index was increased by about ninefold in comparison with controls by sodium saccharin, threefold by potassium saccharin and twofold by calcium saccharin; there was no boost in labelling index with acid saccharin.
