RECONSTRUCTION OF HYPOPHYSIAL-THYROID LINK OF REGULATION OF REPRODUCTIVE SYSTEM IN WOMEN WITH CHRONIC VIRAL HEPATITIS

The article presents the results of a study of levels of hormones of hypophysial-thyroid, system, in women with parenteral chronic viral hepatitis B and C in the light menstrua! disorders. We examined. 77 women of reproductive age: 42 patients with, chronic viral hepatitis and 35 healthy controls. We determined, the concentration of thyroid-stimulating hormone, triiodothyronine, thyroxine, free triiodothyronine and. free thyroxine. We identified. some differences in the concentrations of the studied, hormones in patients with, viral hepatitis depending on the nature of the menstrual cycle

Assessment of functional state of the pituitary-gonadal system in fertile women with acute hepatitis A

Liver is a necessary participant of the metabolism of steroid hormones, so dysfunction of pituitary-gonadal system is possible at viral hepatitis A. We assessed functional state of pituitary-gonadal part of neuroendocrinal regulation system in fertile women with acute hepatitis A and detected changes that can be regarded as compensatory-adaptive shielding of an organism

Modern concepts of viral hepatitis (review of literature)

We conducted an analysis of Russian and foreign literature and an analysis of our researches on the problem of etiology and pathogenesis of viral hepatitis was showed. Viral hepatitis occupies a leading position among infectious disease. Chronic forms of viral hepatitis B and C is the most prevalent. Among them more than 60 % are registered in age from 20 to 39 years. In spite of the fact that pathogenesis, clinical aspects and chronization of these forms are different, they have the general processes in a liver. The changes of these processes of the general systems of an organism (such as the neuroendocrine regulation, lipid status and lipid peroxidation - antioxidant system) have the particular importance. Studying these variables under abnormalities of reproductive health in women with hepatitis is particularly topical

Status of lipid peroxidation and antioxidant protection system in women of reproductive age with viral hepatitis A

The objective of this study was to identify features of the system of lipid peroxidation - antioxidant protection in 31 women of reproductive age with viral hepatitis A. In women with hepatitis A virus (HAV) (main group) there is an increase in the level of double bonds (31,1%) and active products reacting with thiobarbituric acid (141,7%) with a simultaneous decrease in the content of diene conjugates (69,4%), compared with the same indicators in the control group. The level of antioxidant protection in women in main group unlike the control was characterized by a decrease in total antioxidant activity (25,2%), by the inhibition of the activity of superoxide dismutase (29,1%), by decreasing the concentration of a-tocopherol (42,6%) on the background of increase of retinol level (184,6%). In general, the combination of prooxidant and antioxidant factors at HAV can be considered as a condition of oxidative stress (p < 0,05)

Fungal diversity in tomato (Solanum lycopersicum) leaves and fruits in Russia

Sequencing of cloned PCR-amplified species-specific rDNA fragments and isolation of axenic cultures from tomato fruits was carried out to study the mycobiota of tomato leaves and fruits in European part of Russia. DNA was extracted from the leaves, and library of ITS region fragments was constructed in E. coli by cloning of PCR products. This survey revealed fourteen species associated with disease-affected leaves: Septoria lycopersici, Fulvia fulva (=Cladosporium fulvum), Didymella glomerata (=Phoma glomerata), Cladosporium herbarum, Podosphaera fusca, Neocamarosporium goegapense (=Phoma betae), Rhizoctonia solani, Candida albicans, Dioszegia hungarica, Cladosporium cladosporioides, Didymella lycopersici, Alternaria infectoria, Alternaria alternata, Cryptococcus tephrensis. In the leaves from healthy plants without any visible symptoms DNA of three species was found: Aspergillus versicolor, Alternaria alternata, Aureobasidium pullulans. Analysis of axenic cultures isolated from green diseased tomato fruits revealed fungal species: Alternaria alternata, Alternaria solani, Phomopsis phaseoli, Fusarium equiseti, Chaetomium cochliodes, Clonostachys sp., Irpex lacteus, Colletotrichum coccodes. This research provides new information on the mycobiota of tomato in Southern Russia, the main tomato producing region of the country. © 2020, University of Zagreb - Faculty of Agriculture.

Opportunities and prospects biosensor technologies for food analysis

Existing developments in the field of biosensor technologies with the possibility of practical application for establishing food safety indicators were considered. The classification of biosensors is described depending on the physical phenomena underlying its work, the essence and examples of specific developments for the determination of microorganisms, heavy metals and antibiotics in food products are presented. Prospects of biosensor technologies in the food industry are estimated
