Перспективы некорневой обработки раствором глицина для повышения продуктивности укропа огородного

Relevance. Dill is a popular food and medicinal crop (Anethum graveolens L.) of the Celery family (Apiaceae). Seeds of dill are included in the 14th edition of the State Pharmacopoeia of the Russian Federation. However, this crop is characterized by a relatively low yield, which reduces the efficiency of its production. The use of environmentally friendly growth-regulating compounds can significantly increase the yield and improve its quality. As a growth-regulating, foliar treatment with a solution of the amino acid glycine was tested. The amino acid glycine is environmentally friendly and does not pose a danger to humans and animals. The aim of the work was to increase the productivity of garden dill using foliar treatments with glycine amino acid.Materials and methods. Dill varieties Gribovsky and Symphony were chosen as objects to study the effect of the foliar treatments with glycine. Sowing of seeds was carried out at an early date, which for the conditions of the Lipetsk region corresponds to the first decade of April, with a SZT-3.6 seeder with 15 cm row spacing. The seeding rate was 15 kg/ha, the seeding depth was 1-2 cm. were Treatment with glycine solution was achieved in plants rosette phase. The concentration of glycine was 25, 50 and 100 mg / l. The control plants were sprayed with distilled water. The crop was cut during the period of brown seeds on the central umbrella. The content of essential oil was determined by the 14th edition of the State Pharmacopoeia of the Russian Federation (method 1). The content of the main components was determined by gas chromatography.Results. As a result of the research, a positive effect of foliar treatments with glycine on both yield and the content of essential oil in the raw material of dill varieties Gribovsky and Symphony was revealed. As a result of treatments, regardless of concentration, the seeds yield and the yield of essential oil per unit area increased. The increase in the mass of 1000 pieces of fruits was not unambiguous. Based on the results obtained, the effective concentration of amino acid glycine is determined not only by the characteristics of the variety, but also by weather conditions, when, depending on the conditions during the processing period and prior to harvesting, different aspects of the drug's action appear. According to the results of observations for 2 years and an assessment by the sum of the indicators, the optimal concentration of glycine in most cases was 100 mg / l, at the same time, for the Symphony variety for two years, two-foliar treatment with low concentrations of glycine (10 mg / l rosette + 10 mg / l budding).Актуальность. Укроп огородный является востребованной пищевой и лекарственной культурой (Anethum graveolens L.) из семейства Сельдерейные (Apiaceae). Плоды укропа огородного включены в 14 издание Государственной Фармакопеи РФ. Однако эта культура характеризуются относительно низкой урожайностью, что снижает эффективность его производства. Применение экологически безопасных рострегулирующих соединений позволяет существенно повысить урожай и улучшить его качество. В качестве препарата нами была испытана некорневая обработка раствором аминокислоты глицин, который не представляет опасности для человека и окружающей среды. Целью работы явилось повышение продуктивности укропа огородного с помощью некорневых обработок раствором аминокислоты глицин.Материалы и методы.В качестве объектов для изучения действия препарата были выбраны сорта укропа огородного Грибовский и Симфония. Посев растений проводили в ранние сроки, что для условий Липецкой области соответствует первой декаде апреля, сеялкой СЗТ-3,6 с междурядьями 15 см. Норма высева составляла 15 кг/га, глубина заделки семян – 1-2 см. Обработку растений раствором глицина проводили в фазе розетки. Концентрации препарата – 25, 50 и 100 мг/л. Контроль опрыскивали дистиллированной водой. Срезку проводили в период побурения семян на центральном зонтике. Содержание эфирного масла определяли по ГФ 14 методом 1. Содержание основных компонентов определяли методом газовой хроматографии.Результаты. В результате исследований выявлено положительное влияние внекорневых обработок глицином как на урожайность, так и на содержание эфирного масла в сырье укропа сортов Грибовский и Симфония. В результате обработок независимо от концентрации повышалась урожайность и выход эфирного масла с единицы площади. Увеличение массы 1000 штук плодов было не однозначным. Исходя из полученных результатов, эффективная концентрация препарата определяется не только особенностями сорта, но и погодными условиями, когда в зависимости от условий в период обработки и предшествующий уборке проявляются разные аспекты действия препарата. По результатам наблюдений за двумя сортами укропа огородного в течение 2-х лет и оценке результата по сумме показателей оптимальная концентрация глицина в большинстве случаев составила 100 мг/л, вместе с тем для сорта Симфония в течение двух лет была эффективна двукратная обработка низкими концентрациями глицина (10 мг/л розетка + 10 мг/л бутонизация)

Comparative Analysis of the Outcomes of Laparoscopic Right Hemicolectomy with D2 and D3 Lymphadenectomy in the Treatment of Patients with Right Colon Cancer

Introduction. The standard volume of removed groups of lymph nodes for right colon cancer (RCC) has not been determined. According to Japanese clinical guidelines, it is necessary to perform D3 lymphadenectomy in all cases, except stage I, while according to European and Russian clinical guidelines, the standard scope of surgical intervention includes only D2 lymphadenectomy. There are no long-term results regarding differences between D2 and D3 lymph node dissection in RCC; therefore, it is relevant to conduct studies to improve the long-term results of treatment of patients with RCC.Aim: to comparatively evaluate the results of treatment of patients with RCC who underwent laparoscopic right hemicolectomy at A. Tsyb Medical Radiological Research Center.Materials and methods. Conducted from 2018 to 2023, the study included 174 patients with stage I–III RCC: in 106 patients, laparoscopic right hemicolectomy with D2 lymph node dissection was performed, in 68 patients — with D3 lymph node dissection. When assessing the homogeneity and comparability of the groups, according to input parameters, such as clinical stage, gender, age, body mass index and tumor location, their heterogeneity was noted, which did not allow a direct comparative assessment of both groups. To eliminate heterogeneity and adequately select groups, a pseudorandomization technique was used, after which the groups (n = 68) became statistically comparable in all main clinical parameters.Results. Statistically significant differences were obtained in the median duration of surgical intervention, which was longer in the group of patients with D3 lymph node dissection — 150 (60–393) and 213 (70–390) minutes (p < 0.001), and in the median time of flatus passage — 2 (1–4) and 3 (1–9) days, respectively (p = 0.042). Postoperative complications in accordance with the Clavien — Dindo classification occurred in 16 (23.5 %) patients in the group with D2 and in 15 patients (22.1 %) in the group with D3 lymph node dissection (p = 0.999); III–V grade complications were noted in 2 (2.9 %) cases in each group (p = 0.999). Postoperative hospital stay was 6 days for patients in both groups (p = 0.369). During pathomorphological assessment of the removed specimen, the median number of examined lymph nodes was significantly higher in the group with D3 lymph node dissection: 14 (1–52) and 19 (3–59) lymph nodes, respectively (p < 0.001). Involvement of apical lymph nodes (groups 203, 213, 223) was noted in 2 (3 %) patients. In the group with D2 lymph node dissection, distant metastases were recorded twice as often as in the group with D3 lymph node dissection — in 8 (11.8 %) and 4 (5.9 %) patients, respectively (p = 0.365). Local recurrence was not established in any case. The three-year overall and disease-free survival rates were 94.8 ± 3.0 and 100 % (p = 0.149) and 80.5 ± 5.8 and 88.7 ± 5.8 % (p = 0.177), respectively.Conclusions. The experience of using total mesocolonectomy with D3 lymph node dissection for RCC indicates the safety of this surgical intervention in comparison with traditional surgical techniques, while we did not obtain statistically significant differences in patient survival. To definitively determine the role of D3 lymph node dissection in the treatment of patients with RCC, large multicenter randomized studies are certainly needed
