RESUMO
Effect of trematod infection and different concentrations of detergent (20, 50, 80 mg/dm3) onto physical and chemical characteristics of haemolymph of Planorbarius corneus (content of Hb, density, active reaction, amount of Hb per unit of total mass and soft mass of the body) have been investigated. It was noted that all changes of named characteristics caused by detergent were more pronounced in infected mollusks.

The effect of three ferric chloride concentrations (100, 200, 300 mg/l) on the acid-alkaline balance of haemolymph and haemoglobin content in Planorbarius corneus under normal conditions and in the case of infection with parthenites and larvae of Echinoparichium aconiatum was examined. In the medium with an effective concentration of ferric chloride, all snail specimens proved to have acidified haemolymph, by 40-50% in infected samples and 80-85% in uninfected ones. Statistically reliable differences in the haemoglobin content in the haemolymph of infected and uninfected specimens between the control and test media were absent, that proves a weak toxic effect of ferric ions on P. corneus.

The effect of solutions of phenol (100, 250, 400 mg/l), copper sulfate, carbophos and bazudine (0.01, 0.1, 1.0 mg/l) on physical and chemical properties of haemolymph of Lymnaea stagnalis (L.) and Planorbarius corneus (L.) infected with parthenitae of trematodes was studied. Haemolymph viscosity decreases and its active reaction shifts to weakly acid one. Haemolymph density decreases only in solutions of carbophos and bazudine. With heavy infection the concentration of haemoglobin in haemolymph of P. corneus does not change under the effect of phenol but the total volume of haemolymph reduces considerably.
