title: [Histochemical investigations on sialic acid containing compounds in the CNS of teleosts (author's transl)].
abstract: By means of histochemical experiments the qualitative (microphotographs) and quantitative (cytophotometry) distribution of sialic acid containing compounds was investigated in the mesencephalon and cerebellum of Carassius carassius. 1. The perikarya of nerve cells are especially stained by means of Azur A. 2. Nerve fibres, on the other hand, showed positive reactions with colloidal ironhydroxyd (CIH). 3. In different structures of the CNS the intensity of CIH-staining is decreased up to about 55% following treatment with neuraminidase. 4. There are no differences in the reactions of 7 degrees C as compared to 20 degrees C adapted animals.
