[Possibility of using the larvae of anuran amphibians as a test model for the quantitative determination of hypophyseal hormones].

A possibility to use the larvae of ecaudate amphibia as a test model for the quantitative determination of certain hypophyseal hormones has been shown. The physiological reactions of the pigmentary cells in tadpoles of Rana temporaria can be used for a quick and exact testing of the adrenocorticotropic hormone preparations (ACTH): corticotropin and Zn-corticotropin. Evidently the method elaborated for the biological testing of hypophyseal hormones may be used in the production of the endocrinous preparations as a quick assessment of melanocyte-stimulating hormones in integral raw and sublimated hypophyses.
