Opis:
Qualities of microscopical pictures of digenean larvae total slides stained with different acetocarmines were compared. Semichon's acidifying carmine for topographical staining. Schneider's and Belling's carmines for chromosomes as well as iron acetocarmine (modification of the last two) were used. The last stain permits to obtain the slides, that in respect of their colour and quality of microscopical picture may be compared with slides stained with Semichon's carmine. Contrast, colour and reaction of staining depend on concentration of iron acetate in the staining solution. Total slides of investigated larvae stained respectively with Schneider's and Belling's carmines are not enough readable.

Opis:
We have proved highly significant differences in glucose concentration and activity of alpha-amylase in haemolymph of two growth classes of Planorbarius corneus with width of shell smaller and equal or greater than 20 mm, respectively. Both these parameters were higher and were characterized by greater range of individual variability in snails with smaller width of shell. Any differences in levels of total protein and haemoglobin in haemolymph of these animals, in comparison with adult individuals, were not observed. Effect of infection of the pulmonary cavity of investigated snails with Chaetogaster limnaei limnaei on the examined parameters was not ascertained.

Opis:
Pulmonate and prosobranch snails, being necessary hosts for parthenogenetic generations of digenetic trematodes, participate in transmission of all trematodoses important from medical point of view. Role of particular gastropods in epidemiology of these diseases is discussed in details. Invasion of land snails and slugs is mainly passive by eggs containing developed miracidia, white enter ofthese larvae into snails inhabiting fresh-water environments is usually active. Generations in the snail host between miracidia and cercariae vary considerable, depending upon the fluke species. Generally, the cercaria is produced by the sporocyst or the redia. Cercariae usually actively penetrate out of the infected snail and enter water. Leaving out of account cases of encystation of cercariae in external environment (liver flukes of the family Fasciolidae) and active penetration into the final host (blood flukes of the family Schistosomatidae), encystation of these larvae takes place in the second intermediate host. Cercariae of medically important flukes may develop into metacercariae in tissues of fish (liver flukes - Opisthorchis felineus, Clonorchis sinensis, intestinal flukes - Heterophyes heterophyes, Metagonimus yokogawai, Troglotrema salmincola), as well as in crustaceans (pulmonary flukes of the genus Paragonimus), insects (the bipathogenic liver fluke Dicrocoelium dendriticum and other species of the family Plagiorchiidae incidentally found in man), and gastropods (flukes of the family Echinostomatidae, among them perhaps the best known is the Oriental species - Echinostoma ilocanum). In prevention and control of human trematodoses, especially in endemic foci, elimination of snail hosts is a great importance. Using molluscides may be objectionable from the stadpoint of environmental modification through their toxicity to other organisms. Biological control of snail hosts is more attractive. It includes introduction and management of predators, parasites, or pathogens, and intramolluscan competition. Moreover, certain slugs and terrestrial snails participate in transmission of nematode larval stages, including species known as pathogenic for man - the strongylid nematodes of the genus Angiostrongylus). Such infections may be prevented by abstanding from eating raw or inadequately cooked molluscs in endemic areas.

Opis:
Mechanism of pathogenesis of somatic gigantism of water snails infected with development stages of digenetic trematodes is a complex phenomenon. The manner of origination of these abnormalities is often dependent on accepted host-parasite relationship. In the article there are discussed essential foundations of hypotheses explaining snails' parasitological gigantism as a consequence of alterations in gonadal activity (e.g. the hypothesis of disturbances in energetic budget of a host) or of different aspects of the parasite effect on activity of the neurosecretory centres, involved in the control of somatic growth, as well as a possibility of production by parthenites some compounds, acting synergically with host's growth neurohormone.

Opis:
Total protein and activities of: alpha-amylase, alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase in haemolymph of the freshwater snail Lymnaea stagnalis, naturally infected with digenean larvae were investigated. There were no any changes in these parameters in the snails infected with Cercaria tenuispina that occupies mainly haemocoel sinuses. Significant increase of activities of all examined enzymes in haemolymph of the snails infected with larvae belonging to the Furcocercariae group was ascertained. These changes were proportional to the degree of injury of the digestive gland, examined with the use of the thymol turbidity test. Total protein level was significantly higher only in haemolymph of snails with higher values of this test.

Opis:
To supply more documentary evidence for the effect of parasitic infection on activity of neurosecretory centres in the cerebral ganglia of the snail host, caudo-dorsal and light green cells of adult individuals of Lymnaea stagnalis naturally infected with digenean parthenites were subjected to karyometric analysis. In infected animals significant enlargement of nuclear volumes of both examined types of neurosecretory cells was ascertained. Mean nuclear volume of the light green cells in snails infected with Furcocercariae was significantly lower in comparison with the individuals infected with parthenites from groups Echinostomata and Xiphidiocercariae. In remaining cases differences in nuclear volumes among subpopulations distinguished on the ground of an infection factor were not statistically significant.
