There is currently no consensus on the etiopathogenetic nature of endometriosis. The causes of aggressive, progressive, infiltrative growth of endometrioid tissue also remain unclear. An important problem remains the high recurrence rate of endometriosis, despite the availability of modern drug and surgical methods of treatment. The study of the central signaling pathways and the search for new key molecules is of paramount importance for a better understanding of the pathogenesis of the disease, and is also an important step in the development of new strategies for the diagnosis, prevention and treatment of endometriosis.

The aim was to determine the effective dosages of Levofloxacin, an antibacterial drug new for aquaculture,   for the treatment of bacterial haemorrhagic septicaemia in carps and improvement of the physiological state of fish following disease and antibiotic therapy.The methods: the experiments were carried out in aquaculture on juvenile carps infected with a mixed culture of pathogens: highly pathogenic strains of Aeromonas sp., Acinetobacter calcoaceticus, and Citrobacter. Three dosages of Levofloxacin were tested: 250, 500, and 1,000 mg/kg of ichtyomass with feed for 7 days. After the antibiotic therapy, a course of feeding was carried out with SUB-PRO probiotic at a dose of 0.4 g/kg of feed   for 10 days.Scientific novelty: application of a broad-spectrum antibiotic Levofloxacin, an antibacterial drug new for aquaculture, in fish.The results: positive results were obtained with Levofloxacin, an antibiotic new for aquaculture, in the treatment of bacterial haemorrhagic septicaemia. The advantage of the drug is the inhibitory effect on a wide range of bacterial agents and the absence of negative effects on the physiological state of fish. An effective dosage  of Levofloxacin (1,000 mg/kg of ichtyomass for 7 days) was established under experimental conditions. The positive dynamics on the blood parameters of the probiotic drug “SUB-PRO” after the disease and antibiotic therapy was revealed, which provided an increase in the resistance of the fish organism.The practical significance: the findings will be crucial in the development of practical recommendations for  the treatment of bacterial haemorrhagic septicaemia of fish in aquaculture.

Introduction. Adenomyosis has a significantly negative impact on women’s quality of life, causing abnormal uterine bleeding, dysmenorrhea, and chronic pelvic pain and low quality of life. There are no single theory of pathogenesis, unique prognosis and diagnostic markers for adenomyosis. The definitive treatment for adenomyosis is hysterectomy but is not appropriate for patients who wish to preserve their fertility. In this article presents data about etiology, classification, pathogenesis, clinical manifestation and surgical techniques for the treatment of adenomyosis published in medical–scientific databases.Materials and methods. The review includes data from foreign and Russian articles published in the Pubmed journals on this topic.Results. There are a lot of surgical approaches for adenomyosis; however, there is no any universal approach and management guideline for these patients.Conclusion. Adenomyosis – if multifactorial disease. There is no single pathogenesis theory. The clinical picture of adenomyosis varies from asymptomatic to severe pain. The management of adenomyosis is complex and should guide personally for each patient. All techniques and options should be considered and discussed with the patient.
