The article is dedicated to the blessed memory of Tatyana Grigorievna Anishchenko, Doctor of Biological Sciences, professor, who used to hold the position of head of the Department of Human and Animal Physiology of the Biological Faculty of the Saratov State University from 1995 to 2015. This is a look back at the memories of some of her students and a message for new generations about great prospects in obtaining a golden ticket to life and the wonderful world of science.

Application of New Instrumental Methods for Evaluation of the Functional State of Cells of Francisella Tularensis in a Stressful Environment

Authors: Borisova S. V., Kuznetsova E. M., Erokhin P. S., Volokh O. A.

The structure of the cell surface reflects the functional state of the bacterium as a whole. The presence of specific features of cells affects the biophysical characteristics of their surface: charge, free energy and hydrophobicity. The interaction of bacteria with biomolecules and particles is also related to these surface characteristics. The aim of our work was to study the function of F. tularensis 15 NIIEG cells under cultivation under stress using electro-optical (EO) monitoring.

Morphofunctional Changes in Microcirculatory Vessels of Hypertensive Rats’ Cardiac Muscle under Stress

Authors: Uvarova i. A., Romanova T. P.

Investigations of disorders of the heart’s structure and functions at the early stages of development, elaboration of prophylactic measures preventing or decreasing the risk of myocardium in- farction with the presence of the hypertension disease continue to remain unconditionally topical up to now. The aim of this ex- perimental work lies in finding out the morphofunctional signs of cardiovascular lesions produced by stress factors with the presence of arterial hypertension.

The Effect of Emotional and Severe Pathological Stresses on the Level of Arterial Pressure and the Production of Testosterone in Female and Male Rats

Authors: Sindeev S. S., Zinchenko E. M., Ulanova M. V., Gekalyuk A. S., Agranovich I. M., Semyachkina-Glushkovskaya O. V., Kassim M., Sindeeva O. A.

The serum level of testosterone is indicator of organismcapacity. Chronic stress is accompanied by development of more pronounced arterial hypertension in males compared with females that is associated with the decrease in production of testosterone in males but not in females.

ВЛИЯНИЕ ЭКЗОПОЛИСАХАРИДОВ ЛАКТОБАЦИЛЛ НА МИКРОФЛОРУ ТОЛСТОГО ОТДЕЛА КИШЕЧНИКА САМОК КРЫС ПРИ РАЗЛИЧНЫХ ВИДАХ СТРЕССА

Authors: Правдивцева М. И., Karpunina L. V., Сметанина М. Д.

Изучено влияние экзополисахаридов молочнокислых бактерий
– лаксаранов 1596, 1936 и Z – на микрофлору толстого отде-
ла кишечника самок крыс при различных видах стресса. Было
показано, что лаксараны способны стимулировать рост ряда
молочнокислых бактерий и подавлять рост некоторой условно-
патогенной микрофлоры в толстом кишечнике при негативных
воздействиях, вызванных иммобилизационным, холодовым и
этаноловым стрессами, выполняя роль пребиотиков.
 

Гисто-функциональная характеристика кортикальных и околомозговых нефронов почки при реакции на экспериментальный стресс

Authors: Тупикин В. Д., Родзаевская Е. Б., Uvarova i. A., Shorina L. N.

В статье анализируются оригинальные данные гистохимических, энзимохимических исследований, микроморфометрии дифференцированной реакции кортикальных и юкстамедуллярных нефронов почки при стрессе. Обсуждается возможный механизм избирательного повреждения клубочков и других компонентов корковых и околомозговых нефронов.
