Dietary beans and peas provide fibre, resistant starch and other nutrients that are often lacking in the human diet. The influence of native starches of beans and peas (and microwaved preparations) on N utilisation, biochemical indices in blood serum and caecal ecosystem state (SCFA, bacterial enzymes, micro-organisms) was studiedin vivo. The native pea starch contained more resistant starch compared with its bean counterpart (31v.17 %); however, processing decreased these amounts to 25v.10 %. N digestibility was found to decrease considerably in all experimental groups. A considerable reduction was observed in glucose and total cholesterol concentration in rat blood serum as a result of feeding both dietary legume starch preparations under microwave treatment. This indicates that starch of bean origin activated glycolytic bacterial enzymes; however, all the analysed starches were found to reduce the activity of β-glucuronidase. In addition, both dietary bean starches significantly induced the formation of SCFA in the caecal digesta. As compared with the control group, a significant decrease in the pH of caecal and colonic digesta was demonstrated for both bean starch preparations. In comparison with the diet with native pea starch, its microwaved preparation reduced the concentrations of acetic, butyric and propionic acids among caecal SCFA and increased the pH of caecal and colonic digesta. The atherogenic index was significantly lower in rats fed microwaved pea starch. All investigated starch preparations increased the population ofBifidobacteriumspp. in caecal digesta, but were also good substrates for opportunisticEnterococcusorEscherichia coli.

Two experiments were conducted with fatteners (♀ (Landrace × Yorkshire) × ♂ duroc), 50 animals each (10 pigs per group). The fatteners from the control group (C) were administered feed mixtures with genetically modified soybean meal (SBM-GM) used as the only protein source; whereas these from experimental groups (E1–E4) received feed mixtures in which the SBM-GM was replaced with increasing amounts of raw seeds of pea (Experiment I) or blue lupin (Experiment II): E1—5.0%, E2—10.0%, E3—15.0%, and E4—17.5%. Once the fattening period was completed, production results were determined, and selected blood serum indices were assayed to establish the effect of the nutritional factor on body homeostasis and health status of the animals. Pigs from all groups revealed a similar growth rate and meatiness (p > 0.05). In Experiment I serum analyses showed lower (p < 0.001) concentrations of: cholesterol in E1, E3 and E4; creatinine in E1 and E4 and urea in E3 and E4, compared to the C. In Experiment II, lower (p < 0.001) concentrations of aspartate aminotransferase, alanine-aminotransferase, total protein, and Mg were determined in the serum of fatteners from E1–E4 compared to the C. Even though values of all analyzed blood markers differed among the groups, in most cases they fitted within reference values for the species, which indicates the maintenance of body homeostasis. Study results show that there are no contraindications to the use of pea and blue lupin seeds as alternative feed materials to SBM-GM in pig fattening.

Aim of the work. The study of interconnection between atherogenic parameters of the blood serum and cardiac indices during pregnancy with the risk of pre-eclampsia development and prognostication of remote cardio-vascular and/or metabolic pathology among pregnant. Materials and methods. The indices of lipid metabolism in the blood serum of 267 pregnant women were studied using diagnostic sets of reagents. The blood sampling was carried out in II (16-24 gestational weeks) trimester. The general cholesterol (GC) and triglycerides (TG) were determined by colorimetric and enzymatic method; high-density lipoproteins – HDL – by homogenous method of direct determination of HDL-cholesterol concentration in the blood serum without preliminary processing and centrifugation, low-density lipoproteins – LDL – by the direct method. VLDL concentration was calculated by Friedewald formula: LDL = TG/2,2. For evaluation of GC-VLDL concentration TG/2,2 parameter is used, if TG concentration is expressed in mmol/l (or TG/5, if concentration is expressed in mg/100 ml). Cardiac indices were calculated taking into account the lipid parameters according to the correspondent mathematical formulas. Lactate and LDH concentrations were determined by optimized method using diagnostic reagents. Lactate concentration was determined at the use of diagnostic set for determination of lactate concentration, and DLH was also determined by diagnostic set for determination of LDH (DL) activity by optimized method, elaborated taking into account the recommendations of German Association of clinical chemistry (DGKC) after correspondent calibration of automatic analyzer ACCENT-200 II GEN. Depending on the development of clinical presentation of PE 43 women were divided in groups with light and middle severity of course of this pathology. Results and discussion. Among the women with PE development was observed the essential changes in II trimester in the aspect of atherogenic parameters and cardiac indices mainly at the expense of progressing increase of TG in the blood serum (mmol/l: I group - 1,73 ± 0,14, II group - 1,86 ± 0,18 comparing with III control group - 1,51 ± 0,06. The gradual growth of cardiac (atherogenic) indices - AIP, CR and CА and connection between AIP and the levels of maternal serumal TG and arterial pressure were observed in women with PE development at the absence of such connection among the women of control group (p <0,05) . LDH level grew with the progressing of PE severity: for the women of I group LDH level was - 389 ± 1,6 U/l at 778 ± 0,25 in women of II group and 265 ± 0,19 in the control group (p <0,05). Conclusions. It was demonstrated, that hypertriglyceridemia at pregnancy is a predicator relative to PE development and together with progressive growth of atherogenic indices can be considered as prognostic factor for cardiometabolic pathology, especially in women with undergone severe forms of this pathology. It was established, that the increase of LDH level since the second trimester can also testify to the development of PE and remote cardiac pathology in this category of women.

Twelve adult Slovak warmblood sport horses were used to study the effect of dried grape pomace (DGP) on health through blood serum biochemical indicators, and on apparent total tract digestibility of dry matter (DM), organic matter (OM), crude protein (CP), acid detergent fibre (ADF) and neutral detergent fibre (NDF). The digestibility analysis was carried out by two in vivo methods, total faeces collection (TFC) and using lignin as a marker (ADL). Animals were divided into 3 groups: control group (C, without supplementation), experimental group 1 (E1, feed rations + 200 g of DGP) and experimental group 2 (E2, feed rations + 400 g of DGP). In animals, no health problems were detected during the trial. Of the blood serum indicators, only the concentrations of potassium (increase in E2 group compared to C group) and alanine aminotransferase (decrease in E2 group in comparison with E1 and C group) were affected (P &lt; 0.05). The ADL method resulted in underestimated digestibility coefficients due to low recovery rates of lignin (less than 90%) in C group and E1 group. According to TFC, in E1 group higher digestibility coefficients were detected for DM, OM and CP (P &gt; 0.05) compared to C group. However, in E2 group lower digestibility of all the studied nutrients was found (P &gt; 0.05) in comparison with C group and E1 group. These results suggest that DGP could be used in horse diets up to 200 g without negative effect on their health and for a possible digestibility improvement of some nutrients.

In cases of peripheral nerve damage the gap between proximal and distal stumps can be closed by suturing the ends together, using a nerve graft, or by nerve tubulization. Suturing allows regeneration but does not prevent formation of painful neuromas which adhere to adjacent tissues. Autografts are not reported to be as good as tubulization and require a second surgical site with additional risks and complications. Tubulization involves implanting a nerve guide tube that will provide a stable environment for axon proliferation while simultaneously preventing formation of fibrous scar tissue. Supplementing tubes with a collagen gel or collagen plus extracellular matrix factors is reported to increase axon proliferation when compared to controls. But there is no information regarding the use of collagen fibers to guide nerve cell migration through a tube. This communication reports ultrastructural observations on rat sciatic nerve regeneration through a silicone nerve stent containing crosslinked collagen fibers.Collagen fibers were prepared as described previously. The fibers were threaded through a silicone tube to form a central plug. One cm segments of sciatic nerve were excised from Sprague Dawley rats. A control group of rats received a silicone tube implant without collagen while an experimental group received the silicone tube containing a collagen fiber plug. At 4 and 6 weeks postoperatively, the implants were removed and fixed in 2.5% glutaraldehyde buffered by 0.1 M cacodylate containing 1.5 mM CaCl2 and balanced by 0.1 M sucrose. The explants were post-fixed in 1% OSO4, block stained in 1% uranyl acetate, dehydrated and embedded in Epon. Axons were counted on montages prepared at a total magnification of 1700x. Montages were viewed through a dissecting microscope. Thin sections were sampled from the proximal, middle and distal regions of regenerating sciatic plugs.

The effect of triiodothyronine (T3) on the differentiation of cultured neuroblastoma (NB) cells was studied after 9 days of treatment with a dose of 10-4 M/106 cells per day. Using phase contrast microscopy, 30-50% of NB cells showed formation of neurites as a morphological sign of cellular differentiation. The initial rise of the mitosis rate was followed by a plateau. Changes in cyclic nucleotide content, in the triphosphates and in the activity of the enzyme ornithine decarboxylase (ODC) were assessed in 2 human and 2 murine cell lines to serve as biochemical parameters of the cell differentiation induced by T3. Whereas the cAMP level increased significantly (3 to 7 fold compared with its initial value), the cGMP value dropped to 30 to 50% of that of the control group. ATP and GTP increased about 200%, the ODC showed a decrease of about 50%. The present studies show a biphasic effect of T3 on neuroblastoma cells: the initial rise of mitotic activity is followed by increased cell differentiation starting from day 4 of the treatment.

Aggregation And Disaggregation

SummaryADP-induced platelet aggregation and calcium-induced platelet aggregation tests were studied in 14 diabetic patients in the fasting state and half an hour after an intravenous injection of 0.1 unit insulin/kg body weight. Platelet disaggregation was significantly diminished as compared to a normal control group, and their results were negatively correlated with the corresponding serum cholesterol levels. Insulin caused significant diminution in the ADP-induced platelet aggregation as a result of rapid onset of aggregation and disaggregation. There was also a significant increase in platelet disaggregation. In the calcium-induced platelet aggregation test, there was a significant shortening of the aggregation time, its duration, and the clotting time. The optical density fall due to platelet aggregation showed a significant increase. Insulin may have a role in correcting platelet disaggregation possibly through improvement in the intracellular enzymatic activity.

Shwartzman Reaction

SummaryThe role of Hageman factor in triggering intravascular coagulation has been studied in rabbits injected intravenously with Liquoid. Besides changes of coagulation parameters characteristic of consumption coagulopathy (e.g. decrease in platelet counts, fibrinogen levels, factor V activity), a pronounced drop in Hageman factor activity was observed after injection of Liquoid. Likewise, the partial thromboplastin time became prolonged.The activation of Hageman factor in vivo could be prevented by intravenous infusion of lysozyme. Twenty min after starting the lysozyme infusion, the partial thromboplastin time became prolonged from a mean of 29 sec to 108 sec. Animals infused with lysozyme and injected with a lethal dose of Liquoid did not develop a consumption coagulopathy. In the same manner, none of 10 animals treated with lysozyme developed the generalized Shwartzman reaction, whereas in the control group 19 out of 20 animals showed fibrin thrombi in the glomerular capillaries.From the present study it may be concluded that the intravascular coagulation process after intravenous injection of Liquoid is triggered by Hageman factor activation.

Overtraining syndrome is a decrease in physical capacity, emotions and immunity due to training that is too often without adequate periods of rest. Overtraining is often experienced by athletes who daily undergo heavy training with short break periods. This research aims to look at the effect of overtraining aerobic physical exercise on memory in mice. The research method was experimental in vivo with the subject of adult male rat (Rattus Norvegicus) Winstar strain aged 8-10 weeks, body weight 200-250 gr. Divided into three groups, namely the control group, aerobic group and overtraining group. The results of memory tests with water E Maze showed an increase in the duration of travel time and the number of animal errors made by the overtraining group (p = 0.003). This study concludes that overtraining aerobic physical exercise can reduce memory in rat hippocampus.

 Aim. The study of the prevalence and clinical peculiarities of Mycoplasmosis and Chlamydiosis in patients with different pathogenic forms of bronchial asthma (BA) taking into account ethnicity of a patient. Subjects and Methods. The research covered 239 subjects – both the Europeoids and the Mongoloids in the city of Krasnoyarsk and the town of Kyzyl, all of them being BA patients of different stages, including acute stage and practically healthy. We had determined antigens Mycoplasma pneumoniae, Mycoplasma hominis, Chlamydophila pneumoniae, Chlamydophila psittaci and Chlamydia trachomatis in smears of mucosa of pharynx and antibodies to these antigens in peripheral blood serum. Results.  We found high frequency of Mycoplasmosis and Chlamydiosis in the inhabitants of Eastern Siberia, BA patients with different pathogenic forms as compared to control group. We had determined ethnic peculiarities of specific immune response: IgM to М. pneumoniae was revealed in the Europoids more frequently than in the Mongoloids, but IgM to С. pneumoniae and to C. trachomatis, C. trachomatis antigens had been revealed more often in the Mongoloids than in the Europoids. We accepted as clinical equivalents of Mycoplasmosis and Chlamydiosis diagnostics the following signs: temperature around 37C (subfebrile temperature), non-intensive but stable coughing with scanty mucous and muco-purulent sputum, dyspnea of mixed character. Conclusions. Mycoplasma and Chlamydia are meaningful etiologic factors of bronchial asthma. We have found the peculiarities of immune response depending on ethnicity of a patient (ethnic belonging). Clinical markers of Mycoplasmosis and Chlamydiosis should be taken into account in bronchial asthma in order to provide diagnostics timely as well as eradication of infection agents. Because of insufficient knowledge of problem of bronchial asthma related to contamination with Мycoplasma and Chlamydia we put the goal to study the frequency of Mycoplasmosis and Chlamydiosis occurrence in bronchial asthma patients and determine the characteristics clinical course of diseases. We defined antigens Мycoplasma pneumoniae, Мycoplasma hominis, Chlamydophila pneumoniaе, Chlamydophila psittaci, Chlamydia trachomatis in smears of oropharynx mucosa and antibodies to them in blood serum.

Latar Belakang: Hiperkolesterolemia dapat menyebabkan penyakit cerebrovaskuler bahkan kematian. Salah satu pencegahan hiperkolesterolemia adalah dengan pemberian suplemen contohnya menggunakan kulit jeruk purut (Citrus hystrix) yang mengandung saponin, tanin dan flavonoid. Tujuan penelitian ini adalah membuktikan adanya pengaruh pemberian ekstrak ethanol kulit jeruk purut terhadap kadar kolesterol total pada tikus wistar jantan yang diberi diet tinggi lemak. Metode: Penelitian eksperimental  ini menggunakan metode post test only control group design. Jumlah sampel 30 ekor tikus wistar jantan dikelompokkan secara simple random sampling menjadi kelompok kontrol negative (K-), kontrol positif (K+), perlakuan 1 (P1), perlakuan 2 (P2) dan perlakuan 3 (P3). Pada kelompok K+, P1,P2 dan P3 tikus diberi minyak babi sebanyak 3 mg/200grBB/hari selama 3 minggu. Kelompok P1, P2 dan P3 diberikan ekstrak ethanol kulit jeruk purut sebesar 35 mg/200grBB/hari, 70 mg/200grBB/hari, dan 140 mg/200grBB/hari selama 3 minggu. Kadar kolesterol total dihitung dengan metode CHOD-PAP lalu dianalisis secara statistic dengan uji One Way Annova dan uji beda dengan Pos Hoc. Hasil: Dari 25 sampel, rerata kadar kolesterol total (K-):73,90 mg/dl±19,11 mg/dl; (K+):80,00 mg/dl±4,72 mg/dl; (P1):69,94 mg/dl±6,52 mg/dl; (P2):59,10 mg/dl±11,70 mg/dl; (P3):59,74 mg/dl±7,52 mg/dl. (p=0,032). Hasil uji Pos Hoc kelompok yang berbeda signifikan adalah K- dengan P2 (p=0,049), K+ dengan P2 (p=0,008) dan K+ dengan P3 (p=0,010). Kesimpulan: Terdapat pengaruh pemberian ekstrak ethanol kulit jeruk purut terhadap kadar kolesterol total pada tikus wistar jantan yang diberi diet tinggi lemak. Dosis terendah ekstrak kulit jeruk purut yang dapat menurunkan kadar kolesterol total adalah 70 mg/200 grBB/hari.
