[ECOLOGICAL AND GEOGRAPHIC ANALYSIS OF THE SPREAD OF MITES OF THE FAMILY TROMBICULIDAE IN MONGOLIA].

The paper gives data on the fauna of chigger mites (Thrombiculinae), the ectoparasites of small mammals in Mongolia. The ecological and geographic analysis could reveal the major abiotic and biotic determinants of the spread of the chigger mites and make a map of their potential area.

[Dynamics of colonies of the speckled ground squirrel (Spermophilus suslicus Guld., 1770) on the northern boundary of the habitat].

Results of studies in 1999-2009 of the dynamics of five isolated colonies of the speckled ground squirrel (Spermophilus suslicus) at the northern boundary of the habitat of this species (Zaraiskii area, Moscow oblast) are given. An abrupt decrease in the number of this species in colonies was established, as was a multifold decrease (up to 70-90%) in suitable habitats due to the plowing of meadows and build-up of the area. The fragmentation of the optimum habitat of ground squirrels reached a stage where colonies can no longer exist as a stable autonomous system.

[Bile biochemical composition changes in patients with chronic viral hepatitis].

Aim: to study the biochemical composition of cystic and hepatic bile in patients with different forms of viral hepatitis.

Subjects And Methods: Four hundred and fifty-seven patients with different forms of viral hepatitis were examined. The concentration and debit of cholic acid (CA), total cholesterol, total bilirubin, phospholipids, calcium, and C-reactive protein were determined by a bile biochemical study.

[Physical and colloidal properties picture of gall in patients with hepatitis on background standard diet].

Changes of physical properties and colloidal properties and microscopic picture of gall and liver bladder are detected in patients with virus hepatic B and C. A big number of chrystal elements (cholesterol chrystals gall acids, calcium belirubinates, microlytes) as well as cyllindic epithelium cells are revealed. The revealed changes degree isn't conncted with virus hepatitis ethyology, but proportionate to intensity of expressive changes in liver parenchyma.

[Experience with the use of ozone for the treatment of chronic viral hepatitis].

Comparative data are presented illustrating efficiency of the treatment of patients with chronic viral hepatitis by standard therapeutic methods and basal therapy combined with ozone therapy. Patients treated with the use of ozone exhibited better biochemical, virological, and functional characteristics compared with their counterparts managed by standard methods. The results of the study suggest a higher efficiency of combined therapy and reduced risk of development of cholelithiasis.
