[The venereal morbidity in Russia in 1914-1924].

It is accepted to explain increasing of venereal diseases during years of the Revolution by degradation of morality and general disorder of system of state administration and sanitary services in Russia. The cross-verification of information presented in scientific publications and primary information sources makes it possible to look into following issues: degree of venereal (syphilitic) contamination of population of pre-revolutionary Russia; influence on sanitary statistics by erroneous diagnostics and convictions of Zemstvo medicine about predominantly non-sexual path of transmission of syphilis pathogen in Russian countryside; dynamics and sources of venereal morbidity in wartime. The high indicators of pre-revolutionary statistics of venereal infections could be affected by diagnostic errors. The "village syphilis" encountered in public milieu could be completely different disease not sexually transmitted and not chronic form of disease. The primary documents allow to discuss increasing of the number of venereal patients during war years, that however, does not reach catastrophic numbers that can be found even in scientific publications. This is also confirmed by data of Chief Military Sanitary Board of the Red Army for 1920s and statistical materials of People's Commissariat of Health Care of the RSFSR. The high morbidity was demonstrated by same Gubernias that were problematic before the Revolution and only later by those ones through which during the war years passed army masses. In Russia, total level of syphilis morbidity after the end of Civil War occurred to be more than twice lower than in pre-war 1913 and continued to decrease under impact of sanitary measures of Soviet public health.

Detection and full-genotype determination of rare and reassortant rotavirus A strains in Nizhny Novgorod in the European part of Russia.

Reassortant DS-1-like rotavirus A strains have been shown to circulate widely in many countries around the world. In Russia, the prevalence of such strains remains unclear due to the preferred use of the traditional binary classification system. In this work, we obtained partial sequence data from all 11 genome segments and determined the full-genotype constellations of rare and reassortant rotaviruses circulating in Nizhny Novgorod in 2016-2019. DS-1-like G3P[8] and G8P[8] strains were found, reflecting the global trend. Most likely, these strains were introduced into the territory of Russia from other countries but subsequently underwent further evolutionary changes locally. G3P[8], G9P[8], and G12P[8] Wa-like strains of subgenotypic lineages that are unusual for the territory of Russia were also identified. Reassortant G2P[8], G4P[4], and G9P[4] strains with one Wa-like gene (VP4 or VP7) on a DS-1-like backbone were found, and these apparently had a local origin. Feline-like G3P[9] and G6P[9] strains were found to be phylogenetically close to BA222 isolated from a cat in Italy but carried some traces of reassortment with human strains from Russia and other countries. Thus, full-genotype determination of rotavirus A strains in Nizhny Novgorod has clarified some questions related to their origin and evolution.

[Variability of genes encoding nonstructural proteins of rotavirus А (Reoviridae: Rotavirus: Rotavirus A) genotype G9P[8] during the period of dominance in the territory of Nizhny Novgorod (central part of Russia) (2011-2020)].

INTRODUCTION: In Russia, rotavirus A is the main cause of severe viral gastroenteritis in young children. The molecular features that allow a rotavirus of a particular genotype to gain an evolutionary advantage remain unclear, therefore, the study of the genetic diversity of rotaviruses based on genes encoding nonstructural proteins (NSPs) responsible for the reproduction of the virus in the cell is an urgent task. OBJECTIVE: To study the genetic diversity of rotaviruses of genotype G9P[8], which dominated Nizhny Novgorod in 20112020, based on genes encoding nonstructural proteins. MATERIALS AND METHODS: Rotavirus-positive samples were subjected to PCR-genotyping and sequencing of NSP1 NSP5 genes. Phylogenetic analysis was carried out in the MEGA X program. RESULTS: In the period 20112020, G9P[8] rotaviruses with four variants of the NSP2 gene were co-circulating in Nizhny Novgorod. New alleles were noted in 2012 (N1-a-III), 2016 (N1-a-IV) and in 2019 (N1-a-II). The appearance of new variants of other genes occurred in 2014 (E1-3, NSP4), 2018 (T1-a3-III, NSP3) and in 2019 (A1-b-II, NSP1). NSP2 gene had the most variable amino acid sequence (16 substitutions), 2 to 7 substitutions were observed in NSP1, NSP3 and NSP4, NSP5 was conservative. DISCUSSION: The results obtained are consistent with the literature data and indicate the participation of NSP genes in maintaining the heterogeneity of the rotavirus population. CONCLUSION: Until 2018, the genetic diversity of rotaviruses in Nizhny Novgorod was determined by the circulation of strains carrying several alleles of the NSP2 gene and conservative genes NSP1, NSP3NSP5. By the end of the study period, new variants of the genotype G9P[8] were formed in the population, carrying previously unknown combinations of alleles of nonstructural genes.

[Non-mellow season of domestic health resort business in 1914-1922]. / Nebarkhatnyi sezon otechestvennogo kurortnogo dela, 1914­1922.

For a long time, balneotherapy and health resort treatment was considered the privilege of the well-to-do. In Russia, recreational areas developed much later than in Europe. Their development was directly related to restoring the health of the military, the more so since these areas, with few exceptions, were located near the outskirts of the country and the location of large military contingents. The outbreak of the First World War aggravated the lack of capacities of domestic health-resorts. The state expanded the benefits to private and cooperative capital for the development of old resorts and the establishment of new ones. Because of the prolonged delay typical for the tsarist bureaucracy, the work on the development of the domestic health resorts began only in 1916. The war showed the importance of health resorts for preserving the army's combat efficiency and, in some cases, prevented the implementation of these projects due to concern of the local authorities and people towards an increase in the number of outsiders in the formerly sparsely populated areas. After the revolution, the Soviet social support agencies were involved in the distribution of spa vouchers to cash-strapped workers. In the northern provinces, the meager budgets received state funding for the establishment of health resorts on the mined-out salt fields. The local councils of the South set up health resorts in nationalized private dachas. Health resorts of the Black Sea coast and Kavminvod have never stopped their work. They functioned as boarding houses for retired military personnel. After the Civil War, every effort was made to attract leisure travelers to the country's resorts. Voucher-holders and «savage¼ travelers had privileges in food provision. Later, the resort areas were assigned to the first supply category. Despite eight years of military operations on the Russian territory during these years, there were conditions for a sharp growth of mass health resort recreation. This article reviews a large number of original sources and is intended to show, using historical examples, the state importance of health resorts as a means of medical rehabilitation. Paradoxically, it is under difficult political and economic circumstances that health resort recreation has become available for the general population.

[Microbiome of the external auditory canal and preoperative preparation of patients in otosurgery (literature review)]. / Mikrobiom naruzhnogo slukhovogo prokhoda i predoperatsionnaya podgotovka patsientov v otokhirurgii (obzor literatury).

OBJECTIVE: To analyze the effectiveness of methods of antiseptic and hygienic preoperative preparation of the operating field in otosurgery. MATERIAL AND METHODS: A review and an expert assessment of the corresponding research objectives of scientific publications contained in the PubMed and Google Scholar databases have been carried out. RESULTS: Various studies indicate a lower ototoxicity of 5-10% of the drug povidone-iodine compared to others. Drugs, such as Miramistin, Okomistin, Dioxidine, are actively used in otiatrics in Russia, but no data on their ototoxicity have been noted. The collected data point to the relevance and prospects of studying the microbiome of the external auditory canal, assessing its effect on the course of the postoperative period, depending on various methods of preparation (antiseptic, removal of earwax and hair depilation) of the surgical field for otosurgery.

An increase in prevalence of recombinant GII.3[P12] norovirus in sporadic acute diarrhea in children in Nizhny Novgorod, Russia, 2018-2021.

Noroviruses are important etiological agents causing acute intestinal infection in humans. In the last decades, the most common norovirus genotype was GII.4 despite a significant genetic diversity among strains, while the active circulation of noroviruses with other genotypes was observed periodically. This study shows an increase in the detection rate of recombinant GII.3[P12] norovirus in Nizhny Novgorod, Russia, from 6.8% in 2018-2019 to 34.9% in 2020-2021. We performed a phylogenetic analysis based on the nucleotide sequences of noroviruses possessing this genotype obtained in this work, as well as presented in the GenBank database. It has been shown that the circulation of GII.3[P12] noroviruses in the study area was the result of several independent introductions, either directly from the Western Pacific region, or through the Asian part of Russia. The polyphyletic origin, the geographical expansion, and the growth of the epidemic significance of the recombinant GII.3[P12] noroviruses were noted.

Changes in the urine volatile metabolome throughout growth of transplanted hepatocarcinoma.

Trained detection dogs distinguish between urine samples from healthy organisms and organisms with malignant tumors, suggesting that the volatile urine metabolome contains information about tumor progression. The aim of this study was to determine whether the stage of tumor growth affects the chemical differences in the urine of mice and to what extent the "olfactory image of disease" perceived by dogs coincides with the "image of disease" recorded by the mass spectrometer. We used a novel laser ionization mass spectrometry method and propose a mass spectrometric analysis without detailed interpretation of the spectrum of volatile metabolomes in urine. The mass spectrometer we use works without sample preparation and registers volatile organic compounds in air at room temperature without changing the pH of the sample, i.e. under conditions similar to those in which dogs solve the same problem. The experimental cancer models were male BDF-f1 hybrid mice transplanted with hepatocarcinoma tissue, and similar mice transplanted with healthy liver tissue were used as controls. Our data show that both dogs and our proposed laser mass spectrometry method are able to detect both the entire spectrum of volatile organic compounds associated with the disease and minor changes in this spectrum during its course.

[Detection SARS-CoV-2 (Coronaviridae: Coronavirinae: Betacoronavirus: Sarbecovirus) in children with acute intestinal infection in Nizhny Novgorod during 2020-2021].

INTRODUCTION: The novel coronavirus infection COVID-19 is a major public health problem worldwide. Several publications show the presence of gastrointestinal (GI) symptoms (nausea, vomiting, and diarrhea) in addition to respiratory disorders.The aim of this study was the monitoring of RNA of COVID-19 pathogen, coronavirus SARS-CoV-2 (Coronaviridae: Coronavirinae: Betacoronavirus; Sarbecovirus) in children hospitalized with acute intestinal infection (AII), with following molecular-genetic characterization of detected strains. MATERIAL AND METHODS: Fecal samples of children with AII hospitalized in infectious hospital of Nizhny Novgorod (Russia) in the period from 01.07.2020 to 31.10.2021 were used as material for the study. Viral RNA detection was performed by real-time polymerase chain reaction (RT-PCR). The nucleotide sequence of S-protein gene fragment was determined by Sanger sequencing. RESULTS AND DISCUSSION: SARS-CoV-2 genetic material was detected in 45 out of 2476 fecal samples. The maximum number of samples containing RNA of the virus occurred in November 2020 (detection rate of 12.2%). In 20.0% of cases, SARS-CoV-2 RNA was detected in combination with rota-, noro-, and adenoviruses. 28 nucleotide sequences of S-protein gene fragment complementary DNA (cDNA) were determined. Phylogenetic analysis showed that the studied SARS-CoV-2 strains belonged to two variants. Analysis of the S-protein amino acid sequence of the strains studied showed the absence of the N501Y mutation in the 2020 samples, which is a marker for variants with a high epidemic potential, called variants of concern (VOC) according to the World Health Organization (WHO) definition (lines Alpha B.1.1.7, Beta B.1.351, Gamma P.1). Delta line variant B.1.617.2 was identified in two samples isolated in September 2021. CONCLUSION: The detection of SARS-CoV-2 RNA in the fecal samples of children with AII, suggesting that the fecal-oral mechanism of pathogen transmission may exist, determines the necessity to optimize its monitoring and to develop an algorithm of actions with patients with signs of AII under the conditions of a novel coronavirus infection pandemic.

Morphological changes in salivary glands of neonatal rats after intra-abdominal hypertension.

OBJECTIVE: Given the overall prevalence of elevated Intra-abdominal pressure (IAP), along with earlier detection and appropriate therapy of Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS), a significant reduction in patient morbidity and mortality is currently achieved by modern medicine. This article assesses the long-term degree of salivary gland damage in rats depending on the severity of experimental IAH during the neonatal period. MATERIALS AND METHODS: To simulate IAH, newborn rats, under the control of intravesical manometry, were injected into the abdominal cavity with bulking collagen filler in the amount necessary to create a given level of IAP. RESULTS: As shown by the results obtained, rats exposed to intra-abdominal hypertension for ten days had pathological changes in their salivary glands within 120 days. The severity of sialadenitis revealed a correlation with the severity of IAH. Some rats had individual reactions expressed in relative resistance to their organs' abnormalities under hypoxia. CONCLUSIONS: It was concluded that children with severe IAH history might need the disease prevention of the CNS, kidneys, digestive, and respiratory systems and oral diseases, particularly diseases involving the salivary glands. Future research is supposed to investigate further the IAH effect on various organs and tissues, including the dentofacial system.

Phylogeny, taxonomy, and character evolution in Entoloma subgenus Nolanea.

Nolanea is a well-known and long-established subgenus of the genus Entoloma traditionally defined mainly by the mycenoid basidiocarps of the included species. Until now, revisions of this subgenus including molecular data exist only on a regional scale. In this study, the phylogeny of species of Nolanea is analysed based on multi-gene DNA sequences including data of specimens from all continents. New primers are designed for the mitochondrial small subunit and RPB2. The performance of the DNA loci in reconstructing the phylogeny in subg. Nolanea is evaluated. An ancestral state reconstruction is used to infer the character state evolution as well as the importance and reliability of morphological characters used to define subclades below subgeneric rank. Based on the results, seven sections are recognised in Nolanea: the sections Holoconiota, Infularia, Mammosa, Nolanea, Papillata, Staurospora, and the newly described sect. Elegantissima. A large phylogeny based on the fungal barcode rDNA ITS with numerous type sequences is used to evaluate current species concepts. Several names are revealed to be synonyms of older names. Four species new to science are described, namely E. altaicum, E. argillaceum, E. cornicolor, and E. incognitum. Lectotypes, epitypes or neotypes are designated for E. cetratum, E. clandestinum, E. conferendum, E. cuspidiferum, E. hebes, E. minutum, E. nitens, and E. rhodocylix. The re-evaluation of the limits of subg. Nolanea leads to an altered concept excluding species with distinct, lageniform cheilocystidia. The section Ameides is placed in subg. Leptonia. For several species formerly accommodated in Nolanea, but excluded now, viz., E. lepiotoides, E. rhombisporum, E. subelegans, and E. velenovskyi the taxonomic position remains unclear, because of the yet unresolved phylogeny of the whole genus Entoloma.

Potential targets for preclinical diagnostics of acute kidney injury in covid-19 patients (review of literature).

An relevance of the topic was defined by the high occurrence, unfavorable prognosis, lack of diagnostic techniques for early stages of acute kidney injury (AKI) disclosed in patients with COVID-19 (Coronavirus Disease 2019). Screening of medical literature for selection of AKI preclinical biomarkers was considered as main aim of this review. More than 200 publications from Russian Science Citation Index (RSCI), Scopus, The Cochrane Library, and MEDLINE were reviewed. Such risk factors as hypoxemia, increased intrathoracic pressure associated with Acute Respiratory Distress Syndrome (ARDS), hypertension (HT) involving endothelial dysfunction, and Diabetes mellitus were considered to be associated with AKI. There were explicated cytopathic and immune-mediated (cytokine-induced) mechanisms of COVID-19 associated AKI pathogenesis. Multiple methodological approaches were defined for detection and identification of the biomarkers based on urine proteome and metabolome screening. Perspective ways in the preclinical diagnostics of AKI such as detection of the markers of injury of the hypoxia-sensitive proximal canaliculi and the ATP metabolites that reflect first stages of the energy metabolism disorder in the epithelium lining canaliculi were identified in this study. The instantaneous and non-invasive investigation of different markers was regarded as possible method of the prognostication. The accuracy of the diagnosis on the initial stages of AKI, substantiate for preventive start of therapy, and make projections on the disease`s outcome will be improved due to the identification of high-sensitive specific biomarkers.

[Reflux nephropathy in children: pathogenesis and prognosis. Part 2].

The second part of this review is devoted to the issues of modern and promising diagnosis of RN in children. The advantages and limits of the available methods for recording the structural and functional state of the kidneys in childhood are considered. Particular attention is paid to possibilities non-invasive methods for diagnosis and prediction of the disease course. Data on promising biomarkers of the early stages of RN formation and progression are presented. For the purpose of a comprehensive and adequate assessment of morphological changes in the kidneys, the necessity of studying various combinations of cytokines in biological media with the subsequent determination of the optimal spectrum is shown. The sensitivity and specificity of molecular indicators of renal damage reviewed as potential targets for renoprotective therapy in the nearest future.

[Reflux nephropathy in children: pathogenesis and prognosis. Part 1].

The purpose of this review is to analyze the modern literature about renal damage caused by vesicoureteral reflux (VUR). VUR is the most common urodynamic pathology in children and reflux nephropathy (RN), as its main complication, ranks first among the causes of chronic kidney disease (CKD). The risk factors for the appearance and progression of RN are presented in the first part of the review. In the framework of this issue, the main methods of treatment of VUR and associated urinary tract infection are described. The possibilities of conservative and surgical methods for the elimination of reflux for prevention of RN and prognosis of its course are considered. The main morphological aspects of RN formation are described.

[Molecular monitoring of the rotavirus (Reoviridae: Sedoreovirinae: Rotavirus: Rotavirus A) strains circulating in Nizhny Novgorod (2012-2020): detection of the strains with the new genetic features].

INTRODUCTION: The pentavalent rotavirus vaccine has been registered in Russia, however, the vaccination coverage remains low, and an annual increase in the incidence of rotavirus infection is unavoidable. In this regard, molecular monitoring of rotaviruses in order to search for new variants possessing epidemic potential is an urgent task. MATERIAL AND METHODS: PCR genotyping and VP4 and VP7 genes sequencing were used to characterize rotaviruses circulating in Nizhny Novgorod in 2012-2020. The phylogenetic analysis of the strains was carried out using the BEAST software package. RESULTS: The spectrum included 17 genotypes with predominance of G9P[8] (37,4%). Detected in this study genotypes G1P[4], G1P[9], G2P[8], G4P[4], G4P[6], G8P[8], and G9P[4] were not previously identified in Nizhny Novgorod. The circulation of DS-1-like strains possessing genotypes G1P[8], G3P[8], G8P[8], or G9P[8] and a short RNA pattern had been shown. Rotaviruses of the common genotypes were genetically heterogeneous and belonged to different phylogenetic lineages and/or sublineages (P[4]-IV-a; P[4]-IV-b; P[8]-3.1; P[8]-3.3; P[8]-3.4 and P[8]-3.6; G1-I; G1-II; G2-IVa-1; G2-IVa-3; G3-1; G3-3; G4-I-c; G9-III; G9-VI). DISCUSSION: These results extend the available data on the genotypic structure of rotavirus populations in Russia and show the genetic diversity of viral strains. G3P[8] DS-1-like viruses were representatives of the G3-1 lineage, new for the territory of Russia, and had the largest number of amino acid substitutions in the VP7 antigenic epitopes. CONCLUSION: The emergence and spread of strains with new genetic features may allow rotavirus to overcome the immunological pressure formed by natural and vaccine-induced immunity, and maintain or increase the incidence of rotavirus infection.

[Anti-VEGF therapy of wet age-related macular degeneration: analysis of patients lost to follow-up]. / Antiangiogennaya terapiya «vlazhnoi¼ vozrastnoi makulyarnoi degeneratsii: analiz prichin otkaza patsientov ot posleduyushchego nablyudeniya.

Patients lost to follow-up (LTFU) are a well-recognized challenge, both in clinical trials and in real clinical practice. PURPOSE: To study the reasons for patients receiving anti-VEGF therapy for «wet¼ age-related macular degeneration (wAMD) in clinical environment to cease monitoring in the clinic. MATERIAL AND METHODS: This retrospective cohort study included patients with wAMD which received anti-VEGF therapy (ranibizumab, aflibercept) in the Ural State Medical University clinic from 2011 to 2019 (n=241). A subgroup of patients continuing treatment (n=90) was compared with a subgroup of lost to follow up patients (LTFU, n=151, 62.7%). Observation lasting less than 12 months was an exclusion criterion. Statistical analysis included a comparison of demographic and clinical data. The reasons for treatment discontinuation were determined using a phone survey. RESULTS: Characteristic for the LTFU subgroup were shorter duration of the follow-up (p<0.0001), lower number of intravitreal injections (p<0.0001), lower baseline (p<0.0001) and final best corrected visual acuity (p<0.0053) as well as higher values of therapy intensity coefficient (the ratio of the number of intravitreal injections to the duration of the follow-up, p<0.0001). According to the results of the phone survey, the following categories of LTFU were identified: ceased regular monitoring/treatment - 83 (55.0% of the LTFU subgroup), continued treatment in another clinic - 14 (9.3%), deceased - 18 (11.9%), status unknown - 36 (23.8%). The most common causes of LTFU were dissatisfaction with treatment results, financial burden and general comorbidities, which were named by 50, 27 and 17 respondents, respectively. CONCLUSION: In accordance with identified reasons for LTFU, we determined the directions for increasing the effectiveness of wAMD treatment: early diagnosis and start of treatment; using the most effective drugs and therapeutic regimens; increasing the availability of anti-VEGF therapy.

[Phylodynamic characteristics of the Russian population of rotavirus А (Reoviridae: Sedoreovirinae: Rotavirus) based on the VP6 gene].

INTRODUCTION: Rotavirus A is one of the leading causes of acute gastroenteritis in children in the first years of life. Rotavirus infection is currently classified as a preventable infection. The most abundant rotavirion protein is VP6. MATERIAL AND METHODS: Phylogenetic analysis and calculation of phylodynamic characteristics were carried out for 262 nucleotide sequences of the VP6 gene of rotavirus species A, isolated in Russia, using the BEAST v.1.10.4 software package. The derivation and analysis of amino acid sequences was performed using the MEGAX program. RESULTS: This study provides phylodynamic characteristics of the rotaviruses in Russia based on the sequences coding VP6 protein. Bayesian analysis showed the circulation of rotaviruses of three sublineages of genotype I1 and three sublineages of genotype I2 in Russia. The level of accumulation of mutations was established, which turned out to be similar for genotypes I1 and I2 and amounted to 7.732E-4 and 1.008E-3 nucleotides/site/year, respectively. The effective population sizes based on nucleotide sequences of the VP6 I1 and I2 genotypes are relatively stable while after the 2000s there is a tendency of its decreasing. Comparative analysis of the amino acid sequences in the region of the intracellular neutralization sites A (231-260 aa) and B (265-292 aa) made it possible to reveal a mutation in position V252I in a proportion of Russian strains of genotype I1 some strains of genotypes I1 and I2 had mutation I281V. These substitutions were not associated with any sublineages to which the strains belong. The analysis of three T-cell epitopes revealed four amino acid differences (in aa positions 305, 315, 342, 348) that were associated with the first or second genogroup. CONCLUSION: Based on the phylodynamic characteristics and amino acid composition of antigenic determinants, it was concluded that the VP6 protein is highly stable and could potentially be a good model for development of a rotavirus vaccine.

Analysis of Cytokines and ATP in Plucked Hair Follicles.

The concentrations of ATP, IL-6, and IL-10 were measured in extracts of plucked hair follicles from healthy volunteers (normal values) and patients with androgenetic alopecia and then, ATP, IL-6, and IL-10 content was calculated for each follicle. The resulting values were directly proportional to hair follicle length, except for IL-6. The concentration of extracted ATP correlated with lactate dehydrogenase activity indicating cell damage. In patients with androgenetic alopecia, IL-10 content exceeded the normal values in follicles with a length <1 mm and ATP content surpassed the normal in follicles >2 mm long. The content of IL-6 and IL-10 measured by ELISA was comparable with results of mRNA expression assayed by RT-PCR, which attested to moderate level of gene expression. The content of ATP and IL- 10, but not IL-6 depended on the length of plucked hair follicle and on pathogenetic factors affecting hair growth.

Peripheral corticotropin-releasing hormone may protect the gastric musosa against indometacin-induced injury through involvement of glucocorticoids.

The hypothalamic-pituitary-adrenocortical (HPA) system is a key hormonal branch of the brain-gut axis in stress and corticotropin-releasing hormone (CRH) is a principal stimulator of the HPA system. According to our finding activation of the HPA system has gastroprotective role in stress and CRH may protect the gastric mucosa against stress-induced injury through involvement of glucocorticoids. To extend this idea to indomethacin-induced gastric injury in the present work we studied whether CRH may protect the gastric mucosa against ulcerogenic action of indomethacin (IM) through involvement of glucocorticoids. CRH administration (1.25 µg/kg and 2.5 µg/kg, i.p.) markedly, dose-dependently, increased plasma corticosterone level and significantly, dose-dependently, suppressed the occurrence of gastric erosion induced by IM (35 mg/kg, s.c.) in conscious rats. To estimate the role of glucocorticoids in CRH-induced gastroprotection, the effect of CRH (1.25 µg/kg) on the IM-induced gastric erosion was studied after acute reduction of corticosterone release by metyrapone (30 mg/kg, i.p., 30 min before CRH administration) or by CRH receptor type 1 antagonist NBI 27914 (10 mg/kg, i.p., 15 min before CRH administration) and also after occupation of glucocorticoid receptors by their antagonist RU-38486 (20 mg/kg, i.p., 2 h before CRH administration). The effects were compared with those in control rats without acute reduction of corticosterone release or occupation of glucocorticoid receptors. Both metyrapone and NBI 27914 injected shortly before CRH administration caused an inhibition of CRH-induced corticosterone response and prevented protective effect of CRH on the gastric mucosa against the IM-induced erosion. The gastroprotective effect of CRH was also eliminated by the pretreatment with glucocorticoid receptor antagonist RU-38486. The results obtained suggest that exogenous CRH may protect the gastric mucosa against IM-induced gastric injury through involvement of glucocorticoids.
