The specimens were examined at the Institute of Veterinary Research in Anyang, Korea R. and were identified as Rhipicephilus sanguineus (Latreille 1806). The morphological characteristics observed by means of the scanning electron microscope were presented with some SEM microphotographs. As R. sanguineus was firstly discovered to occur in Korea R, a total of 20 species of ticks belonging to 8 genera such as Argas, Amblyomma, Boophilus, Dermacentor, Haemaphysalis, Hyalomma, Ixodes and Rhipicephalus has now been recorded

Despite of presence of a wide choice of antihelminthics, in the Republic of Belarus it is still a real problem of development of preparations that provide long-term treatment and preventive maintenance efficiency against helminthosis. At the same time, helminthes and anthelminthics render the immunosuppression action. The solution of this problem can be a combined application of antihelminthics and adjuvants. There were proposed preparations Albepolis and Averpolis. Their application made it possible not only to release an organism of animals from parasites, but also to correct the state of immune system. The obtained research data confirm the available data about the immunosuppression action of parasites on an organism of animals. There was also is noted the immunosuppression action of Albendazol and Aversektin C in therapeutic doses. Albendazol possess a wide spectrum of action against trematodes, nematodes, cestodes. It interrupts the metabolism, oppresses fumarate reductase activity and adenosine triphosphate synthesis of a parasite. It proved to be low-toxic for homoiothermal animals. Albendazol rendered positove influence on growth, development and increase of cattle productivity.

In the conditions of the Republic of Belarus there was determined the parasitizing influence of Oesophagostomum and their larvae on a metabolism of experimentally infested animals. In course of the study there were generated experimental and control groups of two-month old piglets. Animals of the experimental group were infested in a dose of 15000 invasion larvae per one kg of body weight. Animals of the control group were not infested. Infestation was realized through a mouth with invasion larvae with wet forage. Invasion larvae received by cultivation of excrement tests from infested pigs at temperature of 24 deg C. As a result of the realized research it was established, that Oesophagostomum invasion rendered a substantial influence on the experimental animals. At bimestrious pigs after the experimental infection with Oesophagostomum larvae there were stated the following changes: the disease on 4-30th day was characterized by frustration of function of a gastroenteric path - diarrhea, fever, anaemia, and in the subsequent - stagnation and juvenilism of animals. Oesophagostomum in a host organism caused the pathological changes of haemotological and biochemical blood value which were expressed in quantity decrease of erythrocytes, concentration of haemoglobin, leucocytosis. Eosinophilia was observed in a leukogram. In blood serum there was stated the lowering of crude protein and its fractions content; gradually, but authentically there was noted the increasing of activity serum glutamic oxalacetic transaminase and glutamic-pyruvic transaminase. Bactericidal and lysozymic activity of blood serum decreased. Activity of alkaline phosphatase increased.

In the conditions of the Republic of Belarus there was studied the influence of herbal infusion, tincture, liquid and dry extracts of elecampane (Inula helenium) on morphological and biochemical indexes of pig blood. In course of the study it was established, that preparative forms of elecampane stimulated the formation of blood corpuscle, and also increased of the hemoglobin level in blood of pigs. Administration of elecampane preparations did not cause any authentic changes in blood leukogram of swine; all indicators were within normal limits. Elecampane preparations did not cause changes on the part of biochemical blood indexes of and did not influence the activity of enzymes. Research results showed that herbal infusion, tincture, liquid and dry extracts of elecampane did not render negative influence on swine.
