Objective. Experimentally justify the use of colloidal-hyperosmolar solution based on hydroxyethyl starch HAES-LX-5 % and protein-salt solution based on albumin Lactoprotein with sorbitol (LPS) in burn shock (BS). Materials and methods. The experiments were performed on an experimental model of OS in white male rats. HAES-LX-5 %, LPS solution and control 0.9 % NaCl solution at a dose of 10 ml/kg/day for 7 days were used for infusion therapy. The blood leukocyte intoxication index (LII), medium weight molecules (MWM), C-reactive protein (CRP) were studied. Results and discussion. In the conditions of experimental BS with the introduction of 0.9 % NaCl, the LII on the 7th day significantly increased by 5.37 times (p<0.01) compared with intact animals (0.887±0.108 and 0.165±0.098, respectively). This indicates the development of destructive processes and intoxication of rats in BS. When HAES-LX-5 % and LPS were administered, LII increased only 2.33 times (p<0.01) and 2.41 times (p <0.05) and was significantly lower compared to 0.9 % NaCl. In animals from the group of control pathology there was an increase in blood levels of MWM, on the 1st day by 75.6 %, on the 3rd day – by 159.5 %, and on the 7th day – by 128.0 %, respectively, compared with intact animals. A systemic inflammatory reaction was also formed, which was manifested by an increase in the level of CRP. Pharmacological correction of BS with HAES-LX-5 % and LPS solutions equally inhibited the development of endotoxicosis from the 3rd to the 7th day, which was accompanied by significant (p<0.05) decrease in the level of MWM by 36.2 % and 42.5 %, respectively, after administration of HAES-LX-5 % and by 32.9 % and 38.8 % after administration of LPS relative to control pathology. The use of solutions of HAES-LX-5 % and LPS inhibited the development of inflammation from the 3rd to the 7th day, which was accompanied by a significant (p<0.05) decrease in the level of CRP by 30.7 % and 35.0 % for HAES-LX-5 %, by 29.4 % and 32.9 % for LPS compared to control. Conclusions. It has been experimentally shown in the model of BS that solutions HAES-LX-5 % and LPS show anti-inflammatory activity and reduce the level of endogenous intoxication, inhibiting the development of systemic stress.

Background: The aim of this study was to estimate the blood levels of interleukins (ILs) and tissue factor (TF) in rat blood when modeling acute mesenteric ischemia (AMI) in various stages and during reperfusion. Methods and Results: The study was performed on white non-linear male rats, weighing 200±25g. AMI was simulated by ligating the cranial mesenteric artery at the mesentery root. Then, at certain time intervals, a relaparotomy was performed, blood was collected, and the animals were subjected to reperfusion at different time intervals. During the experiment, the animals were divided into 3 groups depending on the time of ischemia (3 hours [n=10], 6 hours [n=10], and 8 hours [n=10]) followed by reperfusion after the indicated time of ischemia. The level of ILs (IL-6, IL-8, and IL-10) and TF in rat blood serum was determined by EIA. We found that AMI in rats is accompanied by pronounced changes in the immune system and the development of a systemic inflammatory reaction syndrome, which is aggravated by reperfusion. At the same time, the restoration of blood flow after 3-hour ischemia was characterized by an increase in the concentration of IL-6, IL-8, and IL-10; after 6-hour ischemia – by an increase in the IL-6, IL-8 content and TF, and stabilization of the IL-10 concentration. Reperfusion after 8-hour ischemia was accompanied by an increase in the IL-6 concentration, a decrease in the levels of IL-8, IL-10, and TF, which can lead to the progression of necrotic changes in the intestine. Conclusion: The detected changes can serve as laboratory markers that characterize the course and stage of acute mesenteric ischemia.

Anti-inflammatory activity test of ethanolic extract of banana leaf (Musa Paradisiaca L.) on carrageenan-induced paw edema in white male rats (Rattus novergicus L.) has been conducted. It was aimed to investigate and to determine the anti-inflammatory activity and its effective dose. The extract was prepared by maceration method using ethanol 96%. Anti-inflammatory activity test was performed in five different groups. Each group consisted of 5 rats. The 1st group (negative control) was given 0.5% CMC-Na suspension; the 2nd group (positive control) was given diclofenac sodium 9 mg/KgBW; the 3rd, 4th, and 5th groups were successively given the banana leaf extract as much as 500, 750 and 1000 mg/KgBW. Each rat was then induced by 1% carrageenan and tested using subplantar method.  The inflamed paw diameter was measured using a calliper while the inflamed paw volume using pletysmometer. The measurements were done for 6 hours long with intervals of 60 minutes. The data was statistically analyzed using ANOVA (analysis of variance). The results showed that the negative control had a significant difference with the other treatment groups which did not show any anti-inflammatory effect. In conclusion, ethanolic extract of banana leaf has effective anti-inflammatory activity at a dose of 750 mg/KgBW

One of the important treatment landscape widely used for the various disease’s management is phytotherapy, or treatment with herbal medicines. Phytotherapy is used as an independent type of treatment in most cases, and in combination with other drugs as additional treatment. The pain and inflammation control continue as long as there is humanity itself. With old experience of traditional medicine know that Salicaceae have a pronounced anti-inflammatory and analgesic effects. The pharmacological study of the dry extract from Sakhalin willow shoots – the study of analgesic and anti-inflammatory activities in different pharmacological models – was the aim of this work. The analgesic and anti-inflammatory activity of the standardized dry extract from Sakhalin willow shoots (DESWS) was experimentally researched. The study of pharmacological activities of DESWS was carried out at the Educational and Scientific Institute of Applied Pharmacy of the National University of Pharmacy (Kharkov). The effect of DESWS on the course of the inflammatory process was studied in a model of carrageenan edema. Analgesic activity was studied in a model of thermal irritation in white male rats. The study of anti-inflammatory activity in rats on a model of carrageenan edema showed that an effective dose of the studied extract was 30 mg/kg. The greatest reduction in paw edema in rats on the model of carrageenan edema in the first hour of the experiment was observed in the group of animals treated with DESWS at a dose of 30 mg/kg. The anti-inflammatory activity of DESWS was 53.74%, but it was slightly inferior than in the reference drug Diclofenac. It was found that DESWS also shows pronounced analgesic properties at a dose of 30 mg/kg during the first and second hours of the experiment in the model of the limb’s thermal irritation «Hot Plate» in rats. After 120 minutes of experiment the studied activity didn’t change significantly and remained at the level 62.6%. The analgesic effect of DESWS was inferior to antinociceptive activity of the reference drug Metamizole sodium and superior to the studied activity of the reference drug Aspirin. Thus, the dry extract from the Sakhalin willow shoots can affect both pain and inflammation, and it is a potential remedy for further pharmacological research.

The aim of the paper is to study thymus variability in white rats, which were exposed to formaldehyde, and to compare these data with the indicators in control animals. Materials and Methods. The trial enrolled 72 white male rats, initial body weight 40–50 g. The animals were divided into 2 groups (36 rats in each). The first group consisted of control rats. Animals of the second group were exposed to formaldehyde inhalation, 2.766 mg/m3. To characterize the variability of the organ size, centroids were determined. The superposition of landmark configurations was performed using the generalized Procrustes analysis method, MorphoJ 1.06d program. The principal component analysis and canonical analysis of the obtained data were carried out. Results. One-Way ANOVA revealed a high level of intergroup differences in Procrust distance (F=1.34; p<0.0001). The significant effect of the duration of formaldehyde exposure on centroid size was established. The Kruskal-Wallis criterion was 19.778 (p=0.0014). The analysis of the principal components indicated that each of the first 10 components stands for more than 1 % of Procrustes coordinate variance. In this case, the first 7 components compatibly explain 91.398 % of thymus variability. The proportion of the first main component to the total variance of the Procrustes coordinates is 40.236 %. PC1 (-) shows changes in the thymus shape, mostly affecting the tops of its lobes, the middle part of the right boundary and the entire left thymus boundary. The scattering ellipses of the thymus ordinates in rats exposed to formaldehyde, in the first two canonical variables are located higher than those in the control animals. Conclusion. Formaldehyde inhalation leads to thymus changes in white rat. The most significant differences with control data are determined along the second canonical variable. Keywords: thymus, form, rat, formaldehyde, geometric morphometry. Цель. Изучение изменчивости формы тимуса белых крыс, находившихся в условиях влияния формальдегида, и сравнение этих данных с показателями, полученными у контрольных животных. Материалы и методы. Работа выполнена на 72 белых крысах-самцах с начальной массой тела 40–50 г. Животные были разделены на 2 серии (по 36 крыс). Первую серию составляли контрольные крысы. Животные второй серии подвергались ингаляционному воздействию формальдегида (ФА) в концентрации 2,766 мг/м3. Для характеристики изменчивости размеров органов определяли размер их центроидов. Процедуру суперимпозиции конфигураций ландмарок выполняли методом генерализованного прокрустова анализа с использованием программы MorphoJ 1.06d. Проводили анализ главных компонент и канонический анализ полученных данных. Результаты. Однофакторный дисперсионный анализ выявил высокий уровень межгрупповых различий по показателю прокрустовых расстояний (F=1,34; р<0,0001). Установлено значительное влияние продолжительности нахождения животных в условиях воздействия ФА на размер центроида. Критерий Краскела–Уоллиса составил 19,778 (р=0,0014). Анализ главных компонент указывал на то, что каждая из первых 10 компонент объясняет более 1 % дисперсии прокрустовых координат. При этом первые 7 компонент совместно объясняют 91,398 % изменчивости формы тимуса. Вклад первой главной компоненты в общую дисперсию прокрустовых координат составляет 40,236 %. РС1 (–) показывает изменения формы тимуса, в большей степени затрагивающие верхушки его долей, среднюю часть правого контура и весь левый контур тимуса. Эллипсы рассеивания ординат тимусов, принадлежащих крысам, подвергавшимся влиянию ФА, в пространстве первых двух канонических переменных расположены выше по отношению к таковым контрольных животных. Заключение. Ингаляционное воздействие формальдегида приводит к изменению формы тимуса белых крыс. Наибольшие различия с контрольными данными определяются вдоль второй канонической переменной. Ключевые слова: тимус, форма, крыса, формальдегид, геометрическая морфометрия.
