Summary:

The aim: to show the possibility of morphological studies in the diagnosis of primary and secondary tumors of bones. Material and Methods. 105 (72%) patients with primary bone tumors aged from 15 to 66 years and 42 (28%) patients with metastatic bone lesions aged from 42 to 70 years were examined and treated for the period from 2008 till 2015. Material for morphological studies was prepared using an open biopsy tissue slices and a scraping resected tumor during surgery. Soft-tissue component is subjected to cytology. The material for histological study included changes in bone and soft tissue. Results. Giant cell tumor was verified in 45% of cases by histological examination. Multiple myeloma was diagnosed in 15% of patients. Osteogenic sarcoma was diagnosed in 14% of cases. Ewing's sarcoma was diagnosed in 3%, 2% of cases were matched by diagnosed chordoma. According to the data received, cancer metastasis of kidney and lung is mostly diagnosed in men from the group of patients with secondary bone defeat. Metastasis of cancer of the breast in women was predominated. Conclusion. The morphological (histological, cytological) study plays an important role in the diagnosis of bone tumors. The coincidence of the cytological and histological diagnoses was 97%.

Summary:

Objective: assessment of dynamics of reparative processes with the help of cytological examination of the preparations obtained from a conditionally aseptic wound under the action of a complex preparation based on biopolymer chitosan and metal nanoparticles. Material and Methods. A conditionally aseptic wound was simulated in 40 white outbred rats. In comparison and experimental groups cytologic assessment of dynamics of reparative processes was carried out. A number of neutrophilic leukocytes and fibroblastic row perl 00 cells in the preparations is recorded on the 3rd, 5th, 7th, 10th, 14th day from the moment of formation of the wound with the use of the immersion objective. Results. It is established, that in the comparison group the cytologic pattern of impression smear was characterized by decrease in neutrophilic leukocytes and increase in fibroblastic row cells by the 14th day from the moment of formation of the wound. In the experimental group (the use of a complex preparation) more intensive reduction of neutrophilic leukocytes and a significant increase in fibroblastic row cells by the 10th day and a complete healing by the 14th day from the moment of formation of the wound has been determined. Conclusion. When treated by a complex preparation based of biopolymer chitosan and metal nanoparticles earlier occurrence of fibroblastic row cells in preparations and a significant decrease in quantity of neutrophilic leukocytes have been observed.

Characteristics of Clinico-pathologic Presentations of Chronic Gastroduodenitis in Children with Lambliasis Invasion

Year: 2012, volume 8 Issue: №1 Pages: 016-022
Heading: Macro- and Micromorphology Article type: Original article
Authors: Matveeva O.V., Maslyakova G.N., Zhandarova L.F., Popova I.Yu., Neklyudov Yu.A., Alekseev Yu.D.
Organization: Saratov State Medical University
Summary:

The analysis of anamnestic and clinical indices, and also morphological investigation of biopsy materials of mucous coat of stomach and duodenum in children with chronic gastroduodenitis of different etiology including lambliasis invasion is carried out with the purpose of detecting features of clinicopathologic presentations of chronic gastroduodenitis in children with and without lambliasis invasion. Material and methods. 100 patients (50 children with confirmed lambliasis invasion and 50 patients without lambliasis invasion) aged from 2 up to 16 were under observation. The material for histologic study was received as a result of fibrogastroduodenoscopy carried out with target biopsy of fundic, antrum and duodenum mucosa. Results. As a result of the findings moderate pains sited in epigastric and periumbilical regions are characteristic for children with lambliasis invasion; irradiation and cramping characteristics of pains are typical. Conclusion. Manifestation of pains is not connected with the time of day and food intake, manifestation of seasonal prevalence is not typical as well, and progression of inflammatory process in the mucous coat of the stomach and duodenum is declared itself as a diffuse gastritis of the fundic part, a diffuse gastritis of the antral part, subatrophic duodenitis with cyst formation of Brunner's glands, and also the presence of eosinophilic leucocytes in the cellular infiltrate

PECULIARITIES OF MORPHOLOGICAL VERIFICATION IN BREAST CANCER

Year: 2008, volume 4 Issue: №2 Pages: 44-47
Heading: Macro- and Micromorphology Article type: Original article
Authors: S.S. Afanasieva, T.N.Popova, L.F. Zhandarova
Organization: Saratov State Medical University
Summary:

80 case histories of patients with breast cancer were analyzed. During the preoperative examination with objective and instrumental examination methods used the malignant process was suspected but no morphological verification was received. Physical examination revealed 75% cases of cancer. Roentgenologic evidence of malignant tumor was found in 43.5% women. Ultrasound examination of mammary glands showed that 57.7% of patients had cancer symptoms. Despite the repeated puncture aspiration biopsy, preoperative morphological examination proved to be negative. The reasons of morphological verification failure are connected with technical difficulties and morphological features of tumor structure. Negative malignant process verification necessitated the diagnostic partial mastectomy. To achieve ablasticity ofexcisional biopsyit is necessary to keep 2 cm from the tumor. Staged morphological diagnosis verifies the diagnosis in all patients, allowing to choose the adequate extentof surgical procedures.
