Group I (n=3) consisted of intact pigs without surgery, group II (n=3) included animals with ligation of the internal iliac and ovarian arteries on both sides. 12 months after the operation, slaughter was performed and the organo-complex of the uterus with appendages and iliac vessels was taken for electron microscopic pathomorphological examination.Results: comparative results of the study of the uterus, appendages found that the normal structure of the mature uterus was preserved, there were no changes in the structure of the fallopian tubes, tissues and vessels of the ovaries. All changes were found in the area of ligation of the ovarian and internal iliac arteries, although the arteries retained their lumen, but were deformed and surrounded by dense fibrous connective tissue. Conclusion: ligation of the ovarian and internal iliac arteries with absorbable suture material causes only local changes. The sufficiency of collateral blood flow is confirmed by the absence of atrophy of the uterus, fallopian tubes and ovaries, as well as organ deformities.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139168885","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}

There is a steady increase in the frequency of its occurrence in many countries of the world. Hypospadias have various forms of severity, which significantly affects the patient's management tactics, the volume of surgical treatment and the further prognosis for the boy's life. The article describes a case of early prenatal diagnosis of the coronary form of hypospadias in the fetus at 15 weeks of gestation, followed by postnatal verification of the diagnosis. The possibilities of echography in the early detection of distal forms of hypospadias using an integrated approach in the assessment of external genitalia in a male fetus are shown. This complex of hypospadias markers includes an assessment of the size of the penis, the presence of a curvature of its body, the shape of the head of the penis and the presence of signs of cleavage of the foreskin, which are manifested by its rounding. The ineffectiveness of the long-used «tulip» sign for the early diagnosis of distal forms of hypospadias has been demonstrated. The comparison of the echographic picture of the structure of the genitals in normal and hypospadias at 12 and 15 weeks of pregnancy was carried out.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139169900","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}

Methods: multiplex polymerase chain reaction (PCR), PCR for determining the viral load of HIV and HCV, flow cytometry for immunological studies, statistical analysis.Results: the single nucleotide polymorphism in IFNγ gene variant rs2430561 had no prognostic value when determined in the mothers. When recording the TT and AT genotypes of a single nucleotide polymorphism in this gene in a child, it was combined with the probability of the child's infection with HIV/HCV, HIV or HCV, depending on the magnitude of the viral load of HIV and HCV in the mother's blood in different trimesters of pregnancy. The presence of the AA and AT genotypes of the NKG2D gene variant rs2617160 in the mothers had a prognostic value as contributing tothe child infection with HIV/HCV or HIV alone. It was noted that the mechanisms of perinatal viral transmission included a certain level of decline in the absolute number of CD4+ lymphocytes in the woman blood in the second and third trimesters of pregnancy.Conclusions: the presence of AA and AT genotypes of the NKG2D gene variant rs2617160 in woman co-infected with HIV/HCV makes it possible to predict the risk of child infection not only during pregnancy, but also at the planning stage.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138960410","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}

They were all comparable in age (19 ±1 and 19±2 years), gender (all men), physical condition (corresponded to the I-st health group). The immune status was assessed at the Research Institute of Clinical Immunology using standard methodological approaches. Psychological testing was carried out using the Spielberger-Khanin scale, A. Beck's depression diagnostic methodology, and K. Rogers and R. Diamond questionnaire.Results: the differences in the immune response system between the compared groups were revealed only in relation to the parameters characterizing innate immunity. In relation to Medical and Preventive Faculty students, the functional capabilities of natural killers in Military Training Centre students are reduced and the expression of one of the most indicative pattern-recognizing receptors by monocytes is diminished. The analysis of the obtained data of the psychological questionnaire showed that the students of the Military Training Centredemonstrate a lower degree of situational and personal anxiety with a lower degree of adaptation in comparison with the first-year students of the Medical and Preventive Faculty.Conclusion: the immune system indicators responsible for the processes of primary immune response are reduced in military medical students comparing with medical students, which in its turn forms possible prerequisites for the development of clinical manifestations of immune dysfunction. The period of psychological adaptation to the educational process in a medical university is less successful for first-year students of the Military Training Centre. It is necessary to develop measures aimed at increasing the sense of responsibility, psychoemotional and immune adaptation resources.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138980317","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}

Group I – 82 students with excellent academic performance Group II – 491 children with good academic performance. The vegetative index of Kerdo (VIC), the Rufier test, the Genchi test, and the adaptive index (AP) were determined by the method of F. Halberg. The mental performance of younger schoolchildren was studied using Schulte tables.Results: the values of VIC in group I children were 2.5–3.5 times higher. The difference in IR between the groups increased, amounting to 32.88% in the 4th grade. The Gencha sample was characterized by lower values (by 1–2 seconds) in group I children. The difference in AP in the 1st grade was 4.73 sec., then in the 4th grade –6.86 sec. The Schulte tables showed higher values of work efficiency, workability and endurance coefficient along with a decrease in speed and strength indicators and physical endurance.Conclusions: by the end of primary school, the vegetative balance in group I children is between normo- and sympathicotonia. The Gencha test made it possible to establish insufficient resistance of the body to hypoxia. Children of group II demonstrated better adaptive capabilities of the CCC, speed and strength indicators and physical endurance. The data obtained must be taken into account in the pedagogical process with younger schoolchildren and require the development of differentiated recreational activities.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139012481","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 comparison group was 250 conditionally healthy individuals (CG). The complex of the study included methods for detecting herpesviruses: serodiagnostics, PCR-RT. The IFN system (spontaneous and induced production, serum concentration) was tested by ELISA. The study was approved by the ethics board and informed consent was obtained from all patients.Results: the incidence of various mono-mixed herpesvirus infections in patients with ACA-HVI (mono – 26,6% and mixed – 73.4%) and CHVI (mono – 23.1% and mixed – 76.9%) was determined, with EBV dominance in patients of both groups. Serum IFNα deficiency was detected in 100% of cases in both groups, and IFNα in 67% in ACA-HVI and 57% in CHVI. At the same time, significant differences were found between the ACA-HVI and HGVI groups in the level of IFNα reduction: 10 and 5 times, respectively, and for IFNγ – 2.0 and 2.6 times, respectively. The induced IFNα production decreased by 89.1% in ACA-HVI and 47.2% in CHVI. A decrease in induced IFNγ production is characteristic of 50% of patients in both groups. At the same time, the level of induced production of IFN α in patients with ACA-HVI was 9 times lower than in the control group and 4.75 times lower than in the group of patients with CHVI. And the level of induced IFNγ production was 2 times lower compared to CHVI and the control group.Conclusions: when assessing the state of the IFN system in patients with various chronic herpes virus infections, significant differences were revealed. Thus, the most pronounced manifestations of interferonopathy, consisting in a significant decrease in serum IFNα and IFNγ and defects in induced IFN production of both types, are observed statistically significantly more often in the group of patients with an atypical course of the disease than in the group of patients with a typical course of CHVI. The most pronounced disorders in the IFN system and the lack of recovery of IFNα and IFNγ levels in the interrelational period cause atypicity of the course and active viral replication in patients with ACA-HVI.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139219886","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}
