[The histochemical demonstration of biogenic monoamines in normally developing amphibian embryos and in exposure to a permanent magnetic field]. / Gistokhimicheskoe vyiavlenie biogennykh monoaminov u razvivaiushchikhsia zarodyshei amfibii v norme i pri vozdeistvii postoiannogo magnitnogo polia.

It was shown that the permanent magnetic fields at 35-40 mT1 inhibit the activity of biogenic monoamines in developing amphibian embryos. The effect was quantitatively similar to that of PMF at 40 mT1 (3-hour exposure during 6 days). The most significant fluctuations in their activity were observed at the stages of blastoderm formation and gastrulation onset.
