[Causes of the technogenic changes in a freshwater zooplankton community]. / Prichiny tekhnogennogo izmeneniia soobshchestva presnovodnogo zooplanktona.

The situation in water bodies of northwestern Karelia in 1992-2001 was analyzed. As a result of waste discharge from the mining and ore-processing works, weakly mineralized hydrocarbonate-calcium waters changed into highly mineralized waters with the prevalence of potassium ions and sulfates. The total abundance and biomass of zooplanktonic communities decreased. Using the methods of principal components and partial correlations, differences in the responses of zooplankters to mineral pollution were revealed. Typical inhabitants of northern water bodies decreased in numbers, and the species Eudiaptomus gracilis Sars and Heterocope appendiculata Sars (Calanoida) disappeared. On the other hand, eurybiontic species prevailing in water bodies with higher mineralization manifested a positive reaction to the increase in the contents of dissolved mineral compounds. Toxicological experiments made it possible to estimate the survival threshold for E. gracilis and H. appendiculata: the populations of these crustaceans in the polluted water body perished when potassium concentration in water exceeded 50 mg/l.

[The principles of preoperative preparation in genital fistulae of an inflammatory origin]. / Printsipy predoperatsionnoi podgotovki pri genital'nykh svishakh vospalitel'nogo geneza.

Body defense potential was examined in 156 patients with genital fistulas of inflammatory origin. Addition of myelopid, an immunomodulating agent, to the scheme of preoperative treatment was experimentally validated. Preoperative preparation was assessed from the time course of the patients' general status, blood parameters, liver and kidney functions, and immunity status.

[Hormonal regulation of glycemia and metabolic adaptation of newborn babies with intrauterine hypotrophy]. / Gormonal'naia reguliatsiia glikemii i metabolicheskaia adaptatsiia novorozhdennyk/h s vnutriutrobnoi gipotrofiei.

The content of hormones that regulate carbohydrate metabolism was studied during the early neonatal period in 80 full-term neonates with intrauterine hypotrophy. Early application to the breast (2 to 6 hours after the birth) was shown to promote the normalization of the hormonal content. The levels of blood serum C-peptide in the newborn depend on the degree of the rise of the mother's body weight during pregnancy and the presence of toxicosis. The levels of cortisol, somatotropic hormone, immunoreactive insulin and C-peptide were determined by the degree of morphological immaturity of the tissues whereas the content of STH and cortisol by the intensity of hypotrophy as well. The moment of the birth and the early neonatal period of children with intrauterine hypotrophy is characterized by a decrease of the activity of lactate dehydrogenase, alpha-hydroxybutyrate dehydrogenase, creatine kinase and aspartate aminotransferase.

[Clinical significance of mean molecules in the prognosis of pyo-septic complications in patients with genital fistulas]. / Klinicheskoe znachenie srednikh molekul v prognozirovanii gnoino-septicheskikh oslozhnenii u bol'nykh s genital'nymi svishchami.

Fifty-four patients with a variety of inflammatory diseases were investigated. Thirty-four of those were admitted for elective surgical treatment of genital fistulas, and 20 patients underwent a conservative anti-inflammatory treatment. Three degrees of intoxication were identified on the basis of the mean molecular level. The data obtained are an evidence of the predictive value of mean molecular level for the prognosis of pyo-septic complications.
