YIELD AND BIOCHEMICAL STATUS OF CORN DEPENDING ON THE MINERAL NUTRITION AND THE PLANT POPULATION DENSITY

The article presents the results of studies on the effect of various dosages and methods of applying mineral fertilizers on the formation of yield and biochemical composition of corn phytomass depending on the density of standing plants. The studies were carried out on leached heavy loam chernozem. Pre-sowing application of mineral fertilizers in the norm N120 P90 contributed to an increase in the yield of green mass by 26%, and dry matter by 20.6%. The transfer of nitrogen part (N 30) to soil dressing increased the collection of raw biomass by 49.8%, and dry biomass by 27.1% relative to the level of natural soil fertility. An additional raw biomass and dry biomass (39.2 % and 39.3%, relatively) were obtained when N120 P90К60 was applied. On a non-fertilized agricultural background, when nitrogen-phosphorus fertilizers are applied and nitrogen fertilization is carried out, the increase in phytomass yield is noted to a density of 100 ths. units/ha. The maximum yield was obtained at a density of 90 ths units/ha on the background of N120P90К60. A single application of mineral fertilizers supported the improvement in the protein content of the feed and increased the crude protein content in the biomass by 1.04-1.36%. When nitrogen fertilizers were applied in portions, the increase was 2.64 % to the natural fertility level and 1.39 % compared to a single application of nitrogen-phosphorus nutrition. On the non-fertilized agricultural background with increasing density of plants, a decrease in protein provision of the biomass was noted. On the variants with the application of nitrogen-phosphorus fertilizers, the increase was noted up to the density of 80 ths. pcs/ha. And on the background of N120P90К60 it was up to 70 ths. pcs/ha. The same pattern was seen in the content of raw fat

Severe rhinovirus bronchiolitis in premature infant with bronchopulmonary dysplasia

Acute bronchiolitis is an inflammatory disease of the lower respiratory tract with a predominant lesion of small bronchi and bronchioles developing in children under 2 years of age. The main etiological factor of bronchiolitis is the respiratory syncytial virus (RSV), the second place in the etiologic structure belongs to rhinovirus, which causes bronchiolitis usually at 6 months age. Severe bronchiolitis is characterized by the need for auxiliary or artificial lung ventilation (ALV). The main risk groups for severe bronchiolitis include premature infants with or without bronchopulmonary dysplasia (BPD), children with hemodynamically significant congenital heart defects. The article presents a clinical observation of rhinovirus bronchiolitis severe course in a preterm infant aged 4,5 months (post-conceptual age-42 weeks) with severe BPD manifesting with an apnea episode followed by the development of severe respiratory failure requiring mechanical ventilation accompanied by sinus tachycardia. The study demonstrates the possibility of acute bronchiolitis severe course in a premature infant with BPD, not only because of RSV infection, but with rhinovirus infection in the first half of life, which should be considered during virus examination. © 2017, Pediatria Ltd.

Clinical manifestations and forensic medical evaluation of hemothorax

Objtctive: to determine the degree of validity of the allocation of traumatic hemothorax as a medical criterion of a qualifying trait in respect of serious harm to health, which is life-threatening. Material and Methods. A retrospective analysis of 130 case histories of the patients of the Department of Thoracic Surgery was carried out at Penza Clinical Hospital n.a. N.N. Burdenko. The sex, age, severity of the patient's condition, the volume of blood in the pleural cavity, complications of hemothorax (GT), the time between trauma and seeking medical help, and other injuries were analyzed. Results. It was found out that among patients with HT men were 4,2 times more than women. HT developed after traumatic exposure to the thorax in patients of both gender groups. Conclusion. The severity of the condition of patients with HT is determined by the volume of blood in the pleural cavity, complications, the presence of concomitant damages, the number of days between receiving an injury and contacting a medical organization. In the formulation of p. 6.1.10 Order No. 194n of the Ministry of Health and Social Development of April 24, 2008, "On the Approval of Medical Criteria for Determining the Severity of Harm to Human Health" we should add the phrase: "...or a severe or medium hemothorax that causes a life threatening condition..." aiming at an objective forensic evaluation of traumatic h e moth о rax.</p
