Вивчення протизапальної активності настойки та екстракту з листя хости ланцетолистої Актуальність. З літератури відомо, що в сировині хости ланцетолистої міститься велика кількість біоло-гічно активних речовин, зокрема фенольних сполук, сапонінів, органічних кислот, полісахаридів. Завдяки наявності цих БАР у східній медицині дану рослину використовують для лікування захворювань, що супроводжуються розвитком запальних процесів. Виходячи з цього, актуальним є вивчення протизапальної активності засобів із хости ланцетолистої.Мета роботи. Вивчення протизапальної активності настойки та сухого екстракту з листя хости ланцетолистої. Матеріали та методи. Дослідження протизапальної активності було проведено на моделі карагенінового запалення лапи у щурів. Екстракт та настойку з хости вводили внутрішньошлунково в дозах 100 мг/кг та 0,15 мл/кг маси тіла відповідно. Як препарат порівняння використовували диклофенак натрію, який тварини отримували у дозі 8 мг/кг маси тіла. За розвитком набряку спостерігали в динаміці на 1, 3, 6 та 24 години.Результати та їх обговорення. У результаті дослідження настойки та екстракту з хости ланцетолистої ви-явлено протизапальний ефект обох засобів, який, ймовірно, пов'язаний із блокадою ензимів ЦОГ та впливом на такі медіатори запалення, як простагландини. Максимальну протизапальну активність обидва засоби виявили на 24 год розвитку набряку.Висновки. Отримані результати проведених досліджень підтверджують наявність протизапальної актив-ності настойки та сухого екстракту з листя хости ланцетолистої.Ключові слова: настойка; екстракт; хоста ланцетолиста; карагеніновий набряк; протизапальна активність O. Lynda, L. Fira, P. Lyhatskyi Study of anti-inflammatory activity of tincture and hosta lancifolia leaves extractTopicality. It is known from the literature that raw material of hosta lancifolia contains a large amount of biologically active substances (BAS), in particular phenolic compounds, saponins, organic acids, polysaccharides. Due to the BAS presence in Eastern medicine, this plant is used to treat diseases accompanied by the development of inflammatory processes. Hosta is especially popular in treatment of ENT diseases. Therefore, it is important to study the anti-inflammatory activity of hosta lancifolia agents.Aim. To study anti-inflammatory activity of tincture and dry extract from the leaves of hosta lancifolia. Materials and methods. Investigation of anti-inflammatory activity was performed on the model of carrageenan inflammation of the paws in rats. Extract and tincture from hosta were administered intragastrically at doses of 100 mg/kg and 0.15 ml/kg body weight, respectively. As a comparison drug, diclofenac sodium was used, which was administered to animals at a dose of 8 mg/kg body weight. With the development of edema, it was observed in dynamics of 1, 3, 6 and 24 hours.Results and discussion. As a result of study the tincture and dry extract from the leaves of hosta lancifolia, the antiinflammatory effect of both agents was found, which is probably due to blockade of COX enzy...

Among pollutants a significant threat is posed by heavy metals, nitrate fertilizers and industrial waste. However, people also contribute to this threat through bad habits such as smoking and alcohol. All these factors affect health and can cause death. The aim of this study was to investigate the content of reactive oxygen species, markers of cytolysis of hepatocytes, cardoza and the degree of endogenous intoxication in the organism of rats affected by nitrite of sodium on the background of tobacco intoxication. The experiments were carried out on white rats, which were divided into three age categories: immature, mature and old, who for 30 days were exposed to tobacco smoke. The research animals were divided into three groups. One of them for 24 hours before the end of the experiment was given sodium nitrite, the second group was given sodium nitrite 72 hours before the end of the experiment. 30 days after poisoning we tested the contents of reactive oxygen species in neutrophils, cytolysis of erythrocyte membrane was investigated by erythrocytic index of intoxication, hepatocytes and cardiocytes – aminotransferase activity. The degree of endogenous intoxication was evaluated by the content of average weight molecules in blood serum. Poisoning of rats with sodium nitrite on the background of the 30 day intoxication by tobacco smoke led to a significant formation of ROS in neutrophils of rats of different age groups. We investigated the activity of aminotransferases in the blood serum and the above organs of rats after exposing them to sodium nitrite and 30 day tobacco smoke. In the blood serum of adult and aged rats, the activity of alanine aminotransferase increased in these conditions by 2.1 and 1.6 times, respectively. Sodium nitrite, which was an additional factor in the intoxication of the rats of all age groups by smoke, caused more pronounced changes in the activity of the studied enzyme in the blood serum. In the liver and myocardium of rats of different ages a reliable decrease of this index was observed in all experimental groups. There was a significant increase in the serum of rats at different ages of aspartate aminotransferase activity. Aspartate aminotransferase activity in the myocardium of all experimental animals showed a reduction by 1.2–1.3 times after smoke inhalation and 1.5–1.6 times with simultaneous intoxication of the rats by sodium nitrite and tobacco smoke. Sodium nitrite, as an additional toxin raised the penetration capacity of erythrocytes among rats poisoned with smoke.By the end of the experiment, the erythrocyte index of intoxication increased in all age groups: immature rats by 31.7%, mature – by 36.0%, in old rats – by 23.6%. The next step of our research was to investigate the markers of endogenous intoxication – average molecular weight. After the simultaneous intoxication of rats by sodium nitrate and tobacco smoke, at the end of the experiment the content of average weight molecules was λ = 254 and of average mass λ=280 inthe blood serum of rats of all age groups increased by 3.1–3.3 times compared with the intact control group. Immature rats proved most sensitive to the action of sodium nitrite and tobacco.
