The Hydrachnidae water mites of southwestern Siberia in relation to their participation in arbovirus circulation

The phenomenon of Hydrachnidae association with the tick-borne encephalitic viruses complex has been found out during the study of the role of the Hydrachnidae in the arboviruses circulation. We investigated the fauna, studied the quantity variation and trophic relations of these arthropods and blood-sucking Diptera. It was revealed no trophic relations between blood-sucking Diptera and mite species, where TBE strains were isolated from. On the basis of faunistic and virological study we suppose, that Hydroacarinae got an infection with the virus in the nymphal and imago stages, as well as larvae of mosquitos. Authors also note, that trophic relations between blood-sucking Diptera and chiggers (Trombidiidae) may be important in the arboviruses ecology.     

Cytological study of the puncture biopsy specimens of the Douglas' pouch for early diagnosis of ovarian tumors

The conducted studies indicated the diagnostic opportunities of a cytologic analysis of exudates and smears from the Douglas space in patients with a suspicion to ovarian tumor. Tumor cells may be present in the peritoneal cavity not only in different stages of malignant ovarian tumors, but also in secernent and proliferating cystadenomas. A correlation between the peritoneal cell content in patients with different forms of ovarian neoplasms and press-smears from the dissected surface of the removed tumors and histological sections indicated the morphological identitiy of tumor elements and enabled the determination of the cytological criteria for the differential diagnosis of ovarian tumors prior to surgical intervention.
