title: [The effect of ammonium nitrate on the residual nitrogen content in the hemolymph of the pulmonate snail Planorbarius purpura (Mollusca: Pulmonata: Bulinidae) normally and in trematode invasion].
abstract: The effect of the ammonium nitrate (concentrations 2000, 4000, 6000 mg/l) on the content of urea, urea nitrogen and residual nitrogen in the haemolymph of normal Planorbarius purpura and in trematode-infected individuals. It is shown, that stimulation of metabolic processes is more expressed in uninfected specimens, while the trematode-infected ones, the protective process is strained. When the toxin concentration reaches 6000 mg/l, the trematode infected specimens enter the phase of depression with 3.73% hyponitrogen level.
