The effect of quercetin was studied on the multi-eyed flatworm Polycelis felina (Daly.) in laboratory conditions. This is a very suitable test-organism available year-round in nature, easily maintained in the laboratory. The results showed that depending on the dose and recovery period quercetin caused locomotory (behavioral) changes in treated animals including aggregation in groups, resting and unsynchronized movements and twisting of particular body parts. Morphological changes in the form of depigmentation of certain body parts were the result of damage or deterioration ofreticular and parenchymal cells. Numerous basophilic bodies representing parts of damaged and decomposed cells were determined in the gastroderm between the third and seventh day after treatment. All histological preparations revealed significant deterioration of cellular material, and therefore a damaging effect of quercetin on the multi-eyed flatworm Polycelis felina (Daly.). We found an increased number of neoblasts and reticular cells on the third day after treatment, so we concluded that quercetin in the applied doses had a stimulating effect on cell division of neoblasts and reticular cells of treated flatworms.

Dynamics of the telomeric DNA (tDNA) length and the phylogeny of Baikal and Siberian planarians have been studied based on analysis of 18S rDNA and \β-actin gene fragments. It was shown that there is a relationship between tDNA length and planarian size. Giant planarians, with a minor exception, have longer tDNA than do smaller planarians. Phylogenetic affinity between species that have stretched tracks of tDNA, large sizes, and similar habitats denotes the possible role of tDNA in the development of the high regenerative capacity of planarians.
