[World Collections of Parasitic Worms].

This article provides information about the depositories of parasitic worms in the scientific institutes and museums in the United States, Japan, and Europe (the total number of samples and the availability of types of helminths from various classes), as well as information on the availability of electronic catalogues of the collections in the continental, national, and regional centers for collective use. The extent of this material has determined the necessity of creating digital collections and libraries that would represent a new form of storing, displaying, and exchanging information for scientific research. An analysis was performed of the current state of approaches and methods of development of the specialized information retrieval system (IRS) and databases (DBs) on the parasitic worms in Russia on the basis of a common conceptual data model, taking into account their local use (as desktop systems of database management) and access by scientists worldwide via the Internet.

[On the identification of the species Griphobilharzia amoena Platt, Blair, Purdie et Melville, 1991, a parasite of crocodiles in Australia].

The results of the study of typical specimens of the trematode G. amoena from blood vessels of the crocodile Crocodylus johnstoni in Australia are provided. The data obtained on the morphology of this parasite did not confirm the statement of Platt et al.

[Treatment and rehabilitation of patients with chronic opisthorchiasis with skin manifestations].

Our studies demonstrated that chronic opisthorchosis with a skin syndrome is accompanied by a severer clinical course. The course of rehabilitation measures with the use of resort recreation (mud-bad cure) combined with traditional treatment stages makes it possible to considerably enhance the efficiency of treatment of both opisthorchosis and its skin manifestations, and should be applied more often in practice.

[Role of migration processes in oncologic epidemiology of Siberia and Far East].

The paper presents the analysis of the cancer death rates among the population of a Norilsk industrial area and compares the rate and structure among newcomers and natives. The persons who long live in this area more frequently die of cancer diseases than migrants. They have high mortality rates for most sites (the stomach, esophagus, bowel, liver, pancreas).

[Status of cell surface of hepatocytes after exposure to carbon tetrachloride].

In order to estimate contact interactions and deformity of the surface of hepatocytes at a toxic hepatitis, produced by means of carbon tetrachloride, a morphometric analysis of ultrastructures of the contacts and retractions of the surface of hepatocytes, formed at an increased intraorganic pressure has been performed. Carbon tetrachloride produces decrease in adhesive interactions of the cellular surfaces in the area of simple connections, decrease in amount of desmosomes and results in increasing deformity of the surface of hepatocytes. These data support that there exists a universal reaction of the intercellular contacts to a damaging action.

[Effect of trimethoxybenzoate-1,2-oxyethylbenzimidazole and dibazol on the blood supply of the brain].

Tests staged on cats demonstated that intact animals and under conditions of the cerebral circulation restricted through intra-arterial infusion of serotonin-1,2-oxyethylbenzimidazole trimethoxybenzoate hydrochloride and dibazol caused with their intracarotic injection a material increase of the blood supply to the brain, exercising a vasodepressor action on the major functional divisions of its vascular system.
