The aim is to assess the selectivity and metrological characteristics of the spectrophotometric determination method of procaine in certain combined pharmaceutical preparations using a solid-phase extraction sorbent based on hypromellose. \u0000Material and methods. To obtain the solid-phase extraction sorbent, hypromellose and ethyl cyanoacrylate were used along with procaine hydrochloride and sodium hydroxide for the formation of active centers. The sorbent was prepared using a known method. The sorption capacity of the obtained sorbent samples for procaine was 10.2 1.0 g/g. Combined drugs containing procaine and its salts, such as \"Menovazin,\" \"Sulfocamphocaine,\" and \"Otolorin,\" were selected for the study. Eluate optical density registration was performed using a SF-56 spectrophotometer (OKB SPECTR LLC). To evaluate the selectivity (specificity) of sample preparation in chromatographic separation of combined drugs, absorption spectra were registered in the wavelength range of 200-400 nm for eluates obtained using purified water and a 0.1 M hydrochloric acid solution. Procaine and benzocaine identification in the eluate was performed based on the presence of absorption maxima at wavelengths of 222 and 286 nm for benzocaine, and 228 and 292 nm for procaine, respectively. The statistical processing of experimental results and determination of metrological characteristics of the analysis method were carried out in accordance with OFS.1.1.0013 \"Statistical Processing of results of physical, physicochemical, and chemical tests.\" \u0000Results. The selectivity of the spectrophotometric determination method of procaine in certain combined drugs using a solid-phase extraction sorbent based on hypromellose was demonstrated. Selective binding of the analyzed substance with active centers in the sorbent and stepwise elution with purified water and a 0.1 M hydrochloric acid solution during solid-phase extraction eliminates the interfering effect of pharmaceutical components during the UV-spectrophotometry of procaine. The use of a sorbent based on hypromellose leads to improved metrological characteristics and reduces the systematic error of the quantitative determination method by an average of 14.4%.","PeriodicalId":183034,"journal":{"name":"Aspirantskiy Vestnik Povolzhiya","volume":" 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140686670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The information base was made up of the works of domestic and foreign scientists in the field of preferential drug provision, as well as regulatory and organizational documentation on pharmaceutical activities. Preferential prescriptions issued for the period from 2017 to 2021 were analyzed. in the Oryol region. The DDD/ATC methodology was used to estimate consumption. \u0000Results. As a result of the study, it was revealed that preferential antiepileptic drugs are mainly taken by people aged 40-64 years. It has been established that if in 2017-2018 antiepileptic drugs were consumed more by women, then in 2019-2021 by men. Most of the consumers of antiepileptic drugs are federal beneficiaries, mostly disabled people of group II. The highest value of consumption among the top 5 INNs of antiepileptic drugs during the study period is observed for Phenobarbital. For drugs Valproic acid, Topiramate and Carbamazepine is characterized by the dynamics of increasing consumption throughout the study period. For benzobarbital, a pattern of consumption stability was revealed. \u0000Conclusions. Analysis of the structure of consumption of antiepileptic drugs within the framework of the program of subsidized drug provision of the population using the DDD/ATC methodology makes it possible to identify objective data on the dynamics of consumption of antiepileptic drugs of various generations.

Cytological examination of the nasal mucosa allows one to assess the activity of inflammation and the quality of the reparative regeneration process in the postoperative period in rhinological patients. The aim of the study is to diagnose the state of regeneration of the nasal mucosa in rhinological patients in the postoperative period. Material and methods. The study examined 206 patients after septoplasty with vasotomy of the inferior turbinates for a deviated nasal septum and vasomotor rhinitis. The patients were divided into 5 groups depending on the prescribed local regeneration-correcting treatment. All patients underwent cytological examination to assess destructive changes in the epithelium according to the method of L.A. Matveeva.

On the 5-10th day of the postoperative period, destructive processes predominated in rhinocytograms, and cell destruction indices were increased. From the 21st day, signs of proliferation were recorded, and the inflammatory reaction decreased. In the groups whose treatment regimens included reparants, rhinocytograms showed a more rapid decrease in cell destruction indices and a full restoration of cellular representation. A more pronounced reparative effect was detected in a solution of sodium deoxyribonuclease and dexpanthenol. \u0000Conclusion.

Chronic rhinosinusitis is a heterogeneous sinonasal inflammatory disease with constant symptoms and recurrent exacerbations, which affects about 10% of the world's population. Age-related changes in the nasal mucosa (involutive immunodeficiency, atrophic changes, etc.) can affect the course of the inflammatory process, which, in turn, should be borne in mind when planning therapeutic interventions. \u0000AIMS - to study the features of local production of IL-4, IL-6, IL-8, IL-10 in elderly and senile persons with chronic rhinosinusitis. \u0000MATERIALS AND METHODS. The study included patients aged 45 to 90 years with a confirmed diagnosis of \"chronic rhinosinusitis\" in the acute stage, who gave written informed consent to the study. The exclusion criteria were: age up to 45 years; allergic rhinitis; primary immunodeficiency; smoking; oncological disease of any organ system; chronic polypous rhinosinusitis; acute (exacerbation of chronic) diseases of other localization; vaccination; use of immunotropic drugs for 3 months before the start of the study. The scope of the laboratory examination included determination of the concentration of cytokines IL-4, IL-6, IL-8, IL-10 in nasal secretions by enzyme immunoassay. \u0000RESULTS. The analysis of the determined values showed that the maximum level of IL-4 was determined in younger persons with rhonic rhinosinusitis 45-59 years old compared with older persons. In our study, the maximum content of IL-6 occurred in a group of patients aged 75-90 years, while the cytokine level significantly exceeded IL-6 in a group of healthy age-related patients, which indicates a more pronounced inflammatory reaction in patients of the oldest group with chronic rhinosinusitis. Cytokine levels above 600 pg/ml were found mainly in patients with chronic rhinosinusitis. Patients of group 4 had high IL-10 values and their values went beyond the range of the comparison groups. \u0000CONCLUSION. The maximum level of macrophage-monocytic cytokines (IL-6 and IL-8) and anti-inflammatory IL-10 is determined in nasal flushing in patients with chronic rhinosinusitis aged 75-90 years, the highest detectable values of IL-4 are characteristic of patients aged 45-59 years.","PeriodicalId":183034,"journal":{"name":"Aspirantskiy Vestnik Povolzhiya","volume":"486 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140749572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
