Changes in oxidative-antioxidant homeostasis is one of the pathogenetic links in the onset and progression of many nosologies, including chronic pancreatitis (CP) and hypothyroidism (HТ), however, data on the development of oxidative stress (OS) with a combination of CP and HP are insufficient, therefore, determining the role of these systems with a comorbid course of these pathologies is an urgent issue of our time.The aim of the work is to study the state of the oxidative and antioxidant system in patients with CP and CP combined with HT.Material and methods. 96 people were examined, including 26 patients with chronic pancreatitis (group 1), 24 patients with hypothyroidism (group 2), 26 patients with chronic pancreatitis on the background of hypothyroidism (group 3), 20 almost healthy individuals (group 4). Evaluation of the oxidative-antioxidant system and lipid peroxidation was assessed by determining the content of malonic aldehyde in blood plasma (MA pl.) And erythrocytes (MA er.), The level of reduced glutathione, glutathione peroxidase (GP) and glutathione-S-trans-ion (GT). Enzyme activity was calculated per 1 g of hemoglobin (HB).Research results. The analysis of the obtained results revealed clear patterns of changes in the state of the oxidative-antioxidant system and lipid peroxidation in patients with chronic pancreatitis on the background of hypothyroidism. Namely, violation of lipid peroxidation in patients with comorbid pathology, accompanied by an increase in the content of MA er. by 44.87% and the content of MA in blood plasma by 46.42%; oxidative-antioxidant system: decrease in HF in the blood by 51,61%, combined of a compensatory increase in BP - by 48.03% and HT - by 34.76%.Conclusion. Under the conditions of comorbidity of CP and HT, there is a violation of the oxidative-antioxidant system and the state of lipid peroxidation, which is characterized by a significant increase in MA in erythrocytes and MA in plasma against a decrease in glutathione and which complicates the course of the underlying disease, its diagnosis and treatment.

The article presents data on the state of collagen metabolism in terms of oxyproline in the blood, its clinical significance for assessing the severity and outcome of the disease, the criterion for the effectiveness of therapy in children of early age withacute obstructive bronchitis and bronchiolitis. The author recommends to determine the level of free and protein-bound oxyproline in blood plasma, an increase in which reflects the degree of destruction in the bronchopulmonary apparatus. The inclusion of immunomodulin into the basic treatment contributes to an increase in the effectiveness of therapy, a reduction of treatment duration.Keywords: oxyproline, bronchitis and bronchiolitis, immunomodulin, treatment, children

When exposed to noise and vibration in experimental animals there was a decrease in the content of threeiodinethyronine, thyroxin and adrenocorticotropic hormone in blood plasma after 15 and 30 days of experience. An increase in loads led to an increase in the level of threeiodinethyronine and thyroxin under vibration exposure and was normalized with noise. The content of adrenocorticotropic hormone leveled in both cases.

Antimicrobial Protection

Six pharmaceutical pastes were prepared using chemically modified kaolin and talc powders. Tests were conducted to determine their structural and chemical characteristics as well as their antimicrobial protection, thus rendering them suitable for cosmetic and pharmaceutical uses. Kaolin and talc were treated chemically via the cation exchange method to load the clay particles with copper and zinc ions, two cations well known for their antimicrobial properties. Mineralogical analyses were conducted by using X-ray diffraction (XRD) before and after the modification, confirming the mineralogical purity of the samples. Scanning electron microscopy was also used in conjunction with energy dispersed spectroscopy (SEM-EDS) to obtain chemical mapping images, revealing the dispersion of the added metals upon the clay minerals surfaces. Moreover, chemical analysis has been performed (XRF) to validate the enrichment of the clays with each metal utilizing the cation exchange capacity. All modified samples showed the expected elevated concentration in copper or zinc in comparison to their unmodified versions. From the X-ray photoelectron spectroscopy (XPS), the chemical state of the samples’ surfaces was investigated, revealing the presence of salt compounds and indicating the oxidation state of adsorbed metals. Finally, the resistance of pastes in microbial growth when challenged with bacteria, molds, and yeasts was assessed. The evaluation is based on the European Pharmacopeia (EP) criteria.
