LAPAROSCOPIC SURGERY ON UTERUS AND ITS APPENDAGES IN PATIENTS WITH BREAST CANCER

One of the components of pathogenetic treatment of patients with breast cancer is castration. The aim of research is to investigate the significance of video assisted laparoscopic surgery on female reproductive organs in the treatment of breast cancer patients. The study is based on analysis of treatment results of 320 breast cancer patients with noncompromised menstruation and presence of steroid hor- mone receptors in tumor tissue. In comparison to surgical techniques used earlier, video assisted endoscopic surgery allows to decrease the aggressiveness of operation, accelerate the rehabilitation of patients, and lower the length of hospital stay. Radiation castration is not always effective: menstruation recovered in some patients. Besides, radiotherapy can not be recommended for patients with patho- logically transformed ovaries. Chemical castration with Zoladex or other analogous drugs is inaccessible for most patients in Russia

Measuring of spatio-temporal characteristics Z-pinch from deuterated polyethylene

On the S-300 installation at currents up to 2 MA with rise time 100 ns, the investigation of the formation process of high-temperature plasma in fast Z-pinch was carried out. The central part of the loads was made from agar-agar and represented a deuterated polyethylene cylinder with small density 50 and 75 mg/sm3 and 1–2 mm diameter. On the ICT images, obtained in optical and soft X-ray range of a spectrum with 3–5 ns exposition, it is visible that on the axis of the polyethylene cylinder at the current`s rise time a cord is formed and it is separated into bright formations. They were observed on a background of a luminous area which occupied the initial neck volume. On time-integrated pinhole pictures obtained in SXR range (E > 1–4 keV), hot points with minimal size of 50 microns were registered. From the chronograms results, obtained by means of the optical high-speed-streak camera mount along the neck axis with time resolution 1 keV with short duration of 2–4 ns. Simultaneously with X-ray radiation neutrons with the maximal yield of 4.5×109 were registered. The average energy measured in 4 directions under angles with an axis of: 0○ (above the anode), 90○, 180○ (under the cathode) and 270○, were accordingly: 2.4±0.2, 2.5±0.1, 2.5±0.1, 2.5±0.1 MeV
