Objective of the study: to analyze the frequency of structural and functional changes in the thyroid gland of the patients with atrial fibrillation who took amiodarone for 12 months on regular basis. The study was based on findings obtained by examining 80 patients (28 women and 52 men) with cardiosclerosis (diffuse and postinfarction), atrial fibrillation and heart failure IIA at the age of 63.5 ± 1.3 years and 15 healthy individuals of the relevant age (62,4 ± 2,4 years) and relevant sex proportions. The main inclusion criterion was the euthyroid state of the thyroid gland before the beginning of antiarrhythmic therapy. To assess the functional state of the thyroid gland, we studied the content of free thyroxine, triiodothyronine, and antibodies to thyroid peroxidase. The examination was carried out before the therapy, and in 3, 6, 9 and 12 months after the beginning of the study during the course of antiarrhythmic therapy. To detect structural changes in the thyroid gland, we used ultrasound scanning. Depending on the prescribed treatment, the participants were divided into the following groups: group I included the patients who received amiodarone in a dosage of 200 mg per day and basic therapy (n = 60); control group involved the patients who received the basic therapy with antiarrhythmic drugs, digoxin and bisoprolol (n = 20). Results. The therapy with amiodarone for a year resulted in thyroid dysfunction in 33.3% of the patients. Hypothyroidism (20.0%) is leading in the structure of amiodarone-associated thyroid dysfunctions; this condition is subclinically manifested in 11.7% of the patients. The development of amiodarone-induced thyrotoxicosis was observed in 13.3% of the patients, and the first cases of hyperthyroidism were detected not earlier than six months. Under the effect of amiodarone in the first months of the therapy, serum levels of free thyroxine may increase, while free triiodothyronine may decrease, therefore there may be a tendency to slightly increased levels of thyroid-stimulating hormone in the first weeks of the therapy. The above changes in laboratory parameters are transient and are not accompanied by the deterioration of the antiarrhythmic action of amiodarone.

The study involved 58 patients with chronic noncalculous cholecystitis (CNC) divided into two groups. Group I included 30 CNC patients with metabolic syndrome (MS), group II 28 CNC patients without MS. The control group consisted of 20 healthy people. MS was diagnosed according to International Diabetes Federation guidelines (2005). The following anthropometric parameters were determined: body mass index (BMI), waist to hip ratio, blood lipid profile (total cholesterol, triglycerides, high density lipoproteins (HDL), and low density lipoproteins (LDL)). Leptin and insulin levels were measured using commercial ELISA kits «Leptin ELISA» and «Insulin ELISA» (DRG International, Inc., USA) respectively. Insulin resistance index HOMA-IR (Homeostasis Model Assessment of Insulin Resistance) was calculated. It was shown that leptin level in CNC patients with MS was 2.61 times that in healthy subjects (p <0.001) and 2.47 times higher than in CNC patients without MS (p <0.001). Significant direct correlations between leptin blood levels andBMI, HOMA-IR index, triglycerides, and cholesterol were documented. The relationships between blood levels of leptin and the thickness of the gallbladder (GB) wall, the amount of cholesterol crystals in bile, and decreased bile release rate from GB which suggests effect of leptin on the structural and functional changes in GB.

Abstract Background Our aim was to study the morphologic and functional changes in the retina and sclera induced by form deprivation high myopia (FDHM) in guinea pigs and explore the possible mechanisms FDHM formation. Methods Forty 3-weeks-old guinea pigs were randomized into the blank control (Group I, 20 cases) and model groups (20 cases). In the model group, the right eyes of the guinea pigs were sutured 8 weeks to induce FDHM (Group II) and the left eyes were considered a self-control group (Group III). The diopters were measured with retinoscopy. The anterior chamber depth (AC), lens thickness (L), vitreous depth (V) and axial length (AL) were measured using ultrasonometry A. Retinal and scleral morphology and ultrastructural features were observed with light and electron microscopy. The content of malondialdehyde (MDA) and the activity of superoxide dismutase (SOD) in the retina and sclera were detected with a chemical colorimetric assay. Results After remaining stitched for eight weeks, the diopters of Group II changed from (+3.59±0.33) D to (-7.96±0.55) D, and these values were significantly higher than those of Group I (+0.89±0.32) D and Group III (-0.55±0.49) D. The vitreous chamber depth (4.12±0.13) mm and axial length (8.93±0.22) mm of Group II were significantly longer than that of Group I [(3.71±0.23) mm and (7.95±0.37) mm, respectively] and Group III [(3.93±0.04) mm and (8.01±0.15) mm, respectively] (P < 0.05). With the prolongation of form deprivation, the retina and scleral tissue became thinner, the ganglion cell and inner and outer nuclear layers of the retina became decreased, and the arrangement was disordered. In Group II, the activity of SOD was significantly lower than that in Group I and Group III, and the content of MDA was significantly higher in Group II than in Group I and Group III. The differences were statistically significant (P < 0.05). Conclusions These findings suggested that in the FDHM guinea pigs model, the diopter, the vitreous chamber depth, and axial length increased significantly with prolongation of monocular FD time, and morphological structural changes in the retina and sclera were observed. Oxygen free radicals might participate in the formation of FDHM.

BACKGROUND: Valproate sodium is an anticonvulsant drug. Saussurea lappa (costus) is a medicinal plant rich with antioxidants. This research aimed to assess the protective effect of costus root extract against valproate sodium-induced thyrotoxicity.METHODS: Eighty adult male albino rats were equally divided into four groups; group I: untreated control, group II: rats were given 200 mg/kg BW valproate sodium orally and daily for 8 weeks, group III: rats were given 300 mg/kg BW costus root extract orally and daily for 8 weeks, and group IV: rats were given combination of valproate sodium and costus root extract. After 8 weeks, blood samples were collected to evaluate T3, T4 and thyroid-stimulating hormone (TSH) levels. Thyroid gland samples were handled for light and electron microscopic investigation. The heights of follicular cells, area % of collagen fibers and color intensity of thyroglobulin immunoreaction were statistically analyzed. RESULTS: After being given valproate sodium as an induction, hormonal assay showed significant decrease in serum T3 and T4 and significant increase of TSH. Follicular and cellular alterations were shown by light and electron microscopes. Morphometric study revealed increased follicular cell height and area % of collagen fibers and decreased color intensity of thyroglobulin. In contrast, costus root extract appeared to have a protective role against valproate sodium-induced thyroid injury. Most of the changes induced by valproate sodium were not observed after supplementation with the plant root extract.CONCLUSION: Valproate sodium has serious effects on the function and structure of thyroid gland, and this study shows that costus root extract could have a protective effect against these effects.KEYWORDS: valproate sodium, rat, thyrotoxicity, Saussurea lappa

Experimental groups of pigs were treated orally with 120 mg (Group O 120), or 480 mg (Group O 480) of iodine per animal, or intramuscularly with 240 mg (Group I 240) of iodine per animal. Iodine was administered in the form of iodised fatty acid esters (IFAE). The treatment resulted in significantly increased iodine concentrations in tissues and a single dose was sufficient to meet the requirement for the whole fattening period (180 days). Urinary iodine concentrations in all the experimental groups were higher than in the control group C receiving iodine only from conventional feed. Urinary excretion of iodine between days 2 and 5 was more distinctive in orally treated than in intramuscularly treated animals (Figure 1). Iodine concentrations at the end of the fattening period (day 180) were higher in the treated than in the control groups. The treatment effect was more marked in Groups O 480 and I 240 than in Group O 120. The dynamics of blood serum iodine concentrations was similar to urinary concentrations (Figure 2). Mean thyroid gland weights in the groups O 120, O 480, I 240, and C were 9.19, 8.51, 7.10, and 12.01 g, respectively. An opposite tendency was observed for iodine concentrations in thyroid gland dry matter (Figure 3). No effects of any of the treatments on total protein, albumin, total lipids, or cholesterol concentrations in blood serum were observed. Group C showed lower tissue iodine concentrations than any of the experimental groups. The only exception was hepatic tissue in which approximately the same iodine concentrations were found in all the groups. Data obtained in Groups O 120, O 480, and I 240 indicate that decisive for tissue concentrations was rather the dose of iodine than the route of administration. Iodine is stored above all in the thyroid gland and adipose tissue. As can be seen in Figure 4, its concentration was higher in muscles with a higher proportion of fat (neck) than in lean muscles (ham).

Background and objectives: Pesticides play an essential role in crop protection, but their overuse caused environmental pollution and harmful effect on different animal body systems, including the endocrine system. The thyroid gland is one of the homeostatic regulators of metabolic activities, which is affected by the elements of the external environment. There are very limited studies on the effect of indoxacarb on the histological architecture and functions of thyroid gland. Therefore, this study was conducted with the aim of examining functionally and histologically of the thyroid gland exposed to indoxacarb. Method: 24 Swiss albino mice male and female were randomly divided into two groups, each group male and female; group I is a control group given orally with 1ml of distilled water and group II orally treated with 120 mg/kg Bw. of indoxacarb daily for 3 weeks. Blood samples were collected from each mouse under anesthetic to determine the thyroid-stimulating hormone (TSH), thyroxine (T4) levels. Thyroid gland histopathology was attained for the evaluation of the indoxacarb effect. Results: The treated mice showed non-significant increase in T4 levels and a significant decrease in TSH levels but there was no significant difference recorded in T4 and TSH levels between sexes. Histologically, the sections of the thyroid gland of the treated group showed empty and irregular follicles, degeneration of the follicular epithelial tissue, and hyperplasia in the lining of some follicles, the capsule with congestion blood vessels. Conclusion: This study concluded that indoxacarb may act as a thyroid gland toxicant.

Objective. The aim was to study the characteristics of reproductive function in women of fertile age with infertility and hyperfunction of the thyroid gland. Materials and methods. The object of the study was 148 women of fertile age. To compare the indicators obtained by special methods, the control group included the indicators of laboratory and instrumental examination of 30 non-pregnant women of reproductive age. Reproductive function was evaluated in 118 women with hyperthyroidism: 58 retrospectively (group I) and 60 prospectively (group II); the control group consisted of 30 healthy women of reproductive age. Hormonal studies were performed by radioimmune and enzyme immunoassay methods using the automatic analyzer "Cobb" ("Hoffmann La Roche", Switzerland), as well as DPS test systems the analyzer Immulite (USA). Ultrasound of the thyroid gland was performed by a linear sensor with a frequency of 7.5 MHz. The volume of the thyroid gland was calculated according to the Bruno formula. Results. For women of fertile age with hyperthyroidism, a decrease in ovarian reserve is characteristic that is manifested by a significant increase in FSH level (14.1 3.1 IU / L, p 0.05), and a decrease in inhibin B level (35.9 12,7 pg / ml, p 0.05). In 47.7 % of women of fertile age with hyperthyroidism, there is a decrease in ovarian volume and a significant reduction in the average number of antral follicles of normal size (4.34 1.56, p 0.05). Conclusions. Based on the results obtained, it can be assumed that in diffuse toxic goiter there are not only functional disorders (metabolism of hormones of the reproductive system), but also deep organic changes in the structure of the ovaries that leads to a rapid suppression of their functions. In cases of thyroid diseases, the clinical manifestation of these changes is premature and early menopause.

Purpose - comprehensive analysis of the world approach of the use of ranolazine in various clinical trials and the introduction of the program "Smart ECG" to assess the effectiveness of ranolazine.Matherial and methods. Evaluation of European guidelines, analysis of global randomized clinical trials of the ranolazine use, presentation of our own trial: we examined 40 patients with Q wave myocardial infarction (STEMI), were instituted basic therapy according to the modern recommendations which contained interventional treatment with restoration of patency of a heart attack-conditioned coronary artery, double antiplatelet therapy, statins, β-adrenergic blocker, angiotensin-converting enzyme inhibitors, aldosterone antagonists with addition of ranolazine (group I, 30 patients diagnosed STEMI), control - group II, 10 patients with STEMI, who received basic therapy without addition of ranolazine. Results. Analysis of clinical trials (CARISA, MARISA, ERICA, TERISA, MERLIN-TIMI, RIVER-PCI, RIMINI-TRIAL) proved the effectiveness of ranolazine as an antianginal and anti-ischemic drugs. The use of own program «Smart ECG» demonstrates the positive effect of ranolazine on STEMI and requires further implementation.Conclusion. In the European Society of Cardiology guidelines of the management of stable angina pectoris, ranolazine is given a class IIa (level of evidence B) recommendation as a second-line treatment to reduce angina frequency and improve exercise tolerance in subjects who cannot tolerate, have contraindications to, or whose symptoms are not adequately controlled by β- adrenergic blockers, calcium channel blockers and long-acting nitrates. In subjects with baseline low heart rate and low blood pressure, ranolazine may be considered as a first-line drug to reduce angina frequency and improve exercise tolerance - class IIa (level of evidence C) recommendation. Own study, which partially reflects the global approach according to the analyzed clinical studies, demonstrates the positive effect of ranolazine for patients with STEMI - analogue scale EQ–VAS indicates a positive effect, positive influence on the markers of electrical myocardial instability: decreasing of the probability of cases of SDNN decrease, depression of QT and maybe increase of ratio of maximum velocity for differentiated T wave.

Purpose: To determine the clinical significance of diffuse uptake of 68Ga-FAPI in the thyroid.Methods: From January 2020 to September 2021, all subjects with diffuse thyroid uptake in 68Ga-FAPI PET/CT were investigated in our hospital, and compared with the age and sex matched control group. The 68Ga-FAPI uptake in the thyroid gland was analyzed semi-quantitatively using the maximum standardized uptake value (SUVmax), and regression analysis was used to analyze the correlation between available serum thyroid stimulating hormone (TSH) and thyroid peroxidase antibody (TPOAb).Results: Among 815 subjects, 39 subjects were found diffuse FAPI uptake in thyroid gland; 11 subjects refused further examination; a total of 28 subjects were included in the analysis, and 27 subjects were diagnosed with chronic thyroiditis (including 20 subjects with Hashimoto's thyroiditis), 3 subjects with Grave's disease, 3 subjects with only serum TSH elevated, and 1 subject with malignant of thyroid and thyroiditis. The SUVmax of 27 subjects with thyroiditis was 5.75 ± 5.45. No significant correlation was found between the SUVmax and the level of serum TSH (P = 0.389) or TPOAb (P = 0.426).Conclusion: The incidentally discovered diffusely increased 68Ga-FAPI uptake in the thyroid gland is mostly related to chronic lymphocytic (Hashimoto's) thyroiditis. 68Ga-FAPI uptake level correlated neither with the degree of hypothyroidism nor with the titer of TPOAb. In addition, immune-related thyroiditis with immune checkpoint inhibitors may be accidentally found on 68Ga-FAPI, which may be helpful in facilitate timely intervention.

Background. A decrease in bone mineral density (BMD), which occurs in osteomalacia (OM) and osteoporosis (OP), is accompanied by a decrease in the strength properties of bone structures and an increase in the risk of fractures. Despite the same clinical outcome (fractures), the morphostructural, etiological, and pathogenetic characteristics of OP and OM differ qualitatively. The purpose of our work was to study the diagnostic criteria for osteomalacia and osteoporosis in postmenopausal women. Materials and methods. We examined 157 postmenopausal (PM) women aged 57.5 ± 1.2 years, of which 103 women were diagnosed with OP (group I) and 24 were morphometrically diagnosed with osteomalacia (group II), control group (III) included 30 apparently healthy women. X-ray densitometry was performed (osteodensitometer Hologic Discovery (USA)). The blood serum level of 25(OH)D was determined by the enzyme immunoassay on a EUROIMMUN analyzer (Germany). Bone resorption marker C-terminal telopeptide of collagen type 1 (CTx), osteocalcin (OC), and parathyroid hormone (PTH) were assessed by the immunochemiluminescent assay, phosphorus level — by spectrophotometric method using a Cobas 6000 analyzer (Roche Diagnostics, Switzerland). The level of osteoprotegerin (OPG) was determined by enzyme-linked immunosorbent assay on an Axsym analyzer (Abbot, Germany). Statistical processing was performed using Microsoft Office Excel and Statistica 10.0 software. Student’s t-test was used for mathematical processing. When assessing the strength of the correlation coefficients, the Chaddock scale was used. Results. The analysis of the data obtained showed a decrease in BMD (p <0.05) in groups I and II. However, BMD neck, T-test neck, Z-test neck in the group of women with OM were significantly reduced (p < 0.05) in comparison with the group with OP. The levels of 25(OH)D, OC, OPG were also reduced (p < 0.05) in the second group of women compared with the first group. We obtained higher (p < 0.05) indices of PTH and CTx in the group of patients with OM in comparison with the group with OP. The correlation analysis of the obtained results showed a relationship between the level of 25(OH)D and indicators of structural and functional changes in BMD: 25(OH)D and CTx (r = –0.669; p = 0.001), 25(OH)D and BMD neck (r = 0.736; p = 0.002). There was also a direct relationship between BMD neck and CTx (r = –0.463; p = 0.002). Conclusions. The PM women with OM, in comparison with the PM women with OP, developed significantly larger (p < 0.05) changes in the structural and functional state of bone tissue, biochemical markers of bone tissue resorption and remodeling, as well as lower (p < 0.05) level of 25(OH)D. The 25(OH)D level is highly informative in terms of predicting and diagnosing a decrease in BMD and the risk of fractures. The biochemical marker of CTx resorption has a high informative value in terms of predicting, timely diagnosis, and the effectiveness of the treatment.
