title: [Regeneration of freshwater planarians Dugesia tigrina and Polycelis tenuis under the influence of methyl mercury compounds of natural origin].
abstract: We studied the effects of methyl mercury compounds of natural origin on regeneration of the planarians Dugesia tigrina and Polycelis tenuis. Accumulation of methyl mercury in the planarian body leads to a delayed formation of photoreceptor organs in planarians of both species. After a significant traumatic load, the regeneration is suppressed and the death of some control and most experimental animals was observed. The intensity of joining additional cuts depends on the localization of body fragment with a cut and localization of a cut itself.
