AbstractThe work was dedicated to investigation of dynamics of epileptic activity in conditions of extremely high frequency electromagnetic waves (EHF) radiation (7,1 mm, 0,1 mW/cm2) upon focal epileptic activity. Epileptic activity was penicillin-induced (10,000 IU/ml) in the frontal region of the brain cortex in myorelaxed and artificially ventilated rats under acute experimental condition. Thermal effects were absent as far as absorbed dosage of energy did not exceed 0,1 J/ animal. It was established that preliminarily performed hypogeomagnetic period (3,0 h) with the inductivity of geomagnetic field at 5×10−8 Tesla caused the intensification of antiepileptic effects of EHF (15,0 min of exposure). It was pronounced in the form of decrease of foci intensity and significant reduction of lifespan of foci — up to 115,3±13,4 minutes, which was both significant when compared with separate effects of hypogeomagnetic influence (187,3±12,5 min) and EHF (15,0 minutes of exposure) effect (164,2±12,5 minutes) (P<0,05). Besides, EHF (15,0 min) which was made after 3,0 h exposure to hypogeomagnetic influence suppressed generalized seizures in amygdalarly kindled rats.

The aim of the study: to estimate the impact of different cellular phenotype of gastric tumors on the survival of patients treated according to standard protocols. Object and methods of research.The work presents the results of a study conducted on the basis of two medical institutions - the National Cancer Institute and the abdominal oncology and surgery department of the Odessa Regional Oncology Center. 221 patients underwent surgery for gastric cancer (GC) in the period 2007-2013. The average age of patients was 60.88 ± 10.5 years, men - 180, women - 41. Of the total number of operated, 143 patients underwent surgery in the amount of gastrectomy, 78 - subtotal distal resection. Results. All patients included in the study underwent radical surgery. Tumors removed during surgery were examined using histological, cytological, immunohistochemical methods and genetic tests. The obtained results are monitored for the presence/absence of clinical parallels and mathematical correlations. It was concluded that some combinations of immunohistochemical (IHC) markers were effective in separating groups of patients with different biology of gastric cancer. Conclusions. Performing more advanced operations (including the use of D2 lymph dissections) is the most effective option for surgical treatment of microsatellite-unstable and Epstein-Barr virus-associated gastric cancer.

The epileptogenic effects of applications of NMDA and kainic acid solutions to the frontal cortex were attenuated in rats receiving ketogenic diet (80% lipids, 3.3% carbohydrates, and 16.7% proteins) during 4 weeks. Spike latency increased, the power of focal epileptic activity decreased, and focus lifetime was shortened in these animals. Sodium benzylpenicillin and strychnine nitrate less markedly reduced epileptogenic activity.
