[New approaches for prevention of complications after Lichtenstein surgery]. / Novye sposoby profilaktiki oslozhnenii posle operatsii Likhtenshteina.

OBJECTIVE: To describe the new approaches for prevention of complications after hernia repair. MATERIAL AND METHODS: We have proposed the method of combined hernia repair including 2 new techniques to prevent complications after Lichtenstein surgery. The results of 100 surgeries over 5 years (2017-2021) for oblique inguinal hernias were analyzed. Patients were divided into 2 groups by 50 patients depending on surgical technique. We assessed the incidence and severity of postoperative complications, as well as duration of inpatient treatment. RESULTS: According to visual-analogue scale of pain syndrome, local pain intensity in the main group was 1.3 times less than in the control group in 1 hour after surgery, after 1 day - almost 2 times less, after 5 days - 1.7 times less. After 3 months, 1 (2%) patient in the control group had persistent local pain. In the main group, no patient had chronic pain (p<0.05). In the control group, ultrasound of postoperative wound area revealed serous fluid in the mesh area in 36 (60%) patients by the 6th day after surgery. In the main group, there were no ultrasound signs of seroma in any case. Incidence of complications was significantly lower in the main group (p<0.05). Mean length of hospital-stay was significantly less in the main group (6.2±1.1 and 7.1±1.2 days, respectively), p<0.05. CONCLUSION: The proposed new modification of Lichtenstein procedure is an effective method for prevention of the most common postoperative complications.

[Effect of sweet pepper, enriched with selenium, on the transplantable Ehrlich carcinoma in mice].

Effect of sweet pepper enriched and non-enriched with Se on Ehrlich carcinoma growth at Balb/c mice was investigated. 1000 mg/kg of both preparations of sweet pepper (per os administration for mice of 9 months age) inhibited an early stage of tumour growth on 42-62% and 37-65% respectively. No effect on tumour growth was registered for 4 months mice.

[Magnetic parameters of the bees Apis mellifera mellifera (L.) obtained by SQUID-magnetometry]. / Magnitnye parametry pchel Apis mellifera mellifera (L.), poluchennye SKVID-magnitometriei.

It was found using SQUID-magnetometry that the dependence of the magnetization of a bee on the intensity of the applied magnetic fields has the form of a hysteresis loop. By using the parameters of the loop, the magnetic phases were identified and their characteristics were determined. It was found that the diamagnetic component is significant and has a susceptibility = -1,3335 x 10(-8) Gs x cm3/Oe. The ferromagnetite phase is represented by a multidomain magnetite with the coercive force of 70-80 Oe and magnetic saturation momnts of 4 x 10(-5) EMU (Gs x cm3) and residual moment of 3.07 x 10(-6) EMU.
