Indicators of the pituitary-gonadal axis and cortisol level, depending on the individual-typological reaction of the dopaminergic system, to changes in the photoperiod of the year in males living in the European North

Сибирский научный медицинский журнал, Journal Year: 2024, Volume and Issue: 44(5), P. 88 - 94

Published: Oct. 30, 2024

The aim of the work is to compare reaction pituitary-gonadal system and cortisol content in two types dopaminergic reactions male residents Arkhangelsk at change photoperiod during year. Material methods . During one year, a four-time examination was conducted (in March, June, September, December) 20 practically healthy males (average age 33.3 ± 5.3 years). concentration dopamine determined blood plasma, components level were studied serum. Based on analysis individual reactions, sample divided into groups: 1 – subjects increases December compared with September (n = 10); 2 decreases or does not 10). Results. In group 1, decrease testosterone levels revealed: both total (18.16 nmol/l 25.20 September) free (3.77 4.29 pg/ml, respectively) fractions. At same time, higher noted first second (574.22 502.69 nmol/l, respectively). 2, there significant estradiol (0.13 nmol/L versus 0.31 an increase testosterone/estradiol index (173.82 54.01 units, Conclusions. individual-typological variability replacement photoperiods living European North may have indirect effect axis through parallel activation adrenal cortex increased aromatase activity.

Published: Jan. 5, 2023

BACKGROUND: An investigation to determine the reproductive health disorders commonly found in adolescent females residing North peninsula of Kola, Russia. Insubstantial studies on physiological status aged living a territory that has become highly polluted due dust particles apatite-nepheline ore, determines relevance this study and involves identification indicators premorbid state. AIM: To examine under chronic stress condition caused by exposure both anthropogenic as well Arctic environment with an objective reveal possible pre-nosological deviations MATERIAL AND METHODS: We conducted observational, longitudinal analytic "3 waves panel (2019, 2020, 2021) involving 54 female students 1620 years old from medical college city Apatity, Physiological was assessed accordance content hypothalamic-pituitary-adrenocortical system hormones, metabolites lipid peroxidation, antioxidant protection, vitamin D, lipids, carbohydrates using percentile distribution indicator values. Significance differences determined comparative analysis two dependent variables Wilcoxon criterion. RESULTS: Deviations optimal values state were revealed more than 25% females, which manifested themselves increased secretion adrenocorticotropic hormone, cortisol, thyrotropic depleting somatotropic thyroxine reduced protection enzymes. In 95% hypovitaminosis D detected whereas 50% diminished low-density lipoproteins. CONCLUSION: Pre-nosological conditions technogenic pollution testify oppression bodys protective systems are predictors morbidity subject individual correction.

The article dwells on climatic and chemical risk factors that influence health of people living in the RF arctic sub-arctic regions population sub-population levels. We used a model describing cause-effect relations between environmental life expectancy at birth based an artificial neural network to predict future medical demographic situation territories with climate RF. Children’s was examined profoundly due participating representative sampling. comparatively analyzed clinical, biochemical general clinical indicators test reference groups using standard statistical procedures software packages. established average monthly temperatures July grew by 3.4 % over 2010–2019 RF; precipitations January 13.0–15.1 %. presents differentiated estimates emerging (LEB) exerted weather conditions climate.

ULTRAMICROSCOPIC FEATURES OF THYROCYTES STRUCTURE OF RAT’S THYROID GLAND AFTER 60-DAYS SODIUM BENZOATE 162 ADMINISTRATION

Journal of Volgograd State Medical University, Journal Year: 2022, Volume and Issue: 19(1), P. 162 - 166

Published: Jan. 15, 2022

Introduction. Sodium benzoate is widely used in both food and pharmaceutical industries. There evidence of its adverse health effects; However, the effect sodium on ultrastructure thyroid gland cells currently not well understood. Materials methods. The animals were divided into two groups: group 1 was injected with ml solution at a dosage 1000 mg/kg/body weight intragastrically for 60 days, 2 served as control. Samples after tissue processingwere examined under an electron microscope. Results. In experimental group, it found that thyrocytes had cubic, less often flat shape, expanded rough endoplasmic reticulum single accumulations cavities fibrous structures, significant lumps heterochromatin nuclear membrane uneven contours latter, electron-dense mitochondrial matrix. Conclusion. above changes indicate administration locally (through damage to DNA nucleus mitochondria) systemic level decrease leptin levels and, consequence, hypothalamic-pituitary-thyroid axis).

The aim: Evaluation of stress-protective effects various anesthetic techniques on Cesarean section (CS). Materials and methods: 127 pregnant women who delivered by cesarean section, were divided into 4 subgroups: 1a (n = 31) – general anesthesia (GA) with ketamine, 1b GA sodium thiopental, 2a spinal (SA), 2b 34) SA intravenous administration ondansetron at a dose 8 mg. assessment was performed 5 stages: 1 initial; 2 infant extraction; 3 6 hours after surgery; 12 surgery. Results: At stage 2, insulin levels in subgroups decreased 23.9% 34.1%, while there no significant changes. There an increase the cortisol, prolactin cortisol/insulin ratio stages subgroups. Pain intensity increased patients all groups. It highest stage, pain reduced groups, remaining significantly higher Conclusions: dynamics content stress hormones, undergoing CS under give reason to consider this method as optimal adequate one for protection from surgery stress.
