[Biological effects of non-saponifiable sunflower seed oil. Preliminary research].

By inserting near the under-axillary gland of the rats Wistar (one month age) compressed material containing g. 0.250 of non-saponificable sunflower seeds oil, it has been noted an increase of the number of the mitosis in the under-axillary gland, in the lung and some mitosis in the liver. Such results are similar to those obtainable by administering, with similar method 0.050 g. of 3,4benzopyrene or 0.100 g. of the hydrocarbon oxidization products. The histological analysis have been effected on the organs of rats sacrificed one month after inoculation.
