Published: July 2015

AbstractIrritable bowel syndrome (IBS) belongs to functional gastrointestinal disorders and is characterized by abdominal pain and change in stool consistency and/or bowel habits. Etiological factors include gastrointestinal peristalsis disturbances, visceral hypersensitivity, chronic inflammation of the mucous membrane, dysbacteremia, intestinal infections, psychosomatic and nutritional factors. Gastrointestinal motility disturbances in case of IBS are manifested by the inhibition of the intestinal passage, which favors the development of constipation or occurrence of diarrhea.was to evaluate IBS symptoms and demonstrate the relationship between physical activity and place of residence amongst Warsaw University students.The study was conducted in march, 2014 using a specific questionnaire, amongst Warsaw University students. The study group comprised 120 female patients, aged between 19 and 27 years (M=23.43; SD=1.29). The chi-square test was used for analysis, p<0.05 was considered as statistically significant.The BMI of investigated patients ranged between 16.30-31.22 kg/mIBS symptoms are common amongst Warsaw University students. In case of respondents with low physical activity, abdominal pain or discomfort occurred more often. It has been demonstrated that diet and stress might contribute to the occurrence of abdominal symptoms, being evidence of IBS.

AbstractEctopic pancreas is a rare congenital disorder defined as pancreatic tissue lacking vascular or anatomic communication with the normal body of the pancreas. Most cases of ectopic pancreas are asymptomatic, but it may become clinically evident depending on the size, location and the pathological changes similar to those observed in case of the normal pancreas. It is often an incidental finding and can be located at different sites in the gastrointestinal tract. The most common locations are: the stomach, duodenum or the proximal part of small intestine. The risk of malignancy, bleeding and occlusion are the most serious complications. Despite the development in diagnostics, it still remains a challenge for the clinician to differentiate it from neoplasm.In this report, we described a case of 28-years old woman who presented recurrent epigastric pain. The upper gastrointestinal endoscopy revealed gastrointestinal stromal tumor on the border of the body and antrum of the back wall of great curvature of the stomach. The histopathological examination after surgery showed heterotopic pancreatic tissue. Ectopic pancreas should be considered in the differential diagnosis of gastric mass lesions.

Published: July 2015

AbstractThe genetic stability of ORF1a encoding non-structural proteins nsp1, nsp2, nsp3 and nsp4 of equine arteritis virus (EAV) has been analysed for nearly seven years in a persistently infected stallion of the Malopolska breed. Between November 2004 and June 2011, 11 semen samples were collected. Viral RNA extracted from semen of this carrier stallion was amplified, sequenced and compared with the sequences of the other known strains of EAV. Sequence analysis of ORF1a showed 84 synonymous and 16 non-synonymous mutations. The most variable part of ORF1a was the region encoding nsp2 protein with 13 non-synonymous substitutions. The degree of amino acid identity between isolates ranged from 98.91 to 100%. Only single non-synonymous mutations were detected in nsp1 (one substitution) and nsp4 (two substitutions). The most stable was nsp3 in which no amino acid substitutions were observed during the whole period of observation.

Abstract
Campylobacter jejuni inactivation by high pressure processing (HPP) in poultry meat (chicken breast) was investigated. The pressure was created by high hydrostatic pressure piston-cylinder food processor. Contaminated with C. jejuni (108 CFU g−1) samples of ground poultry meat were hermetically sealed in a polyamide-polyethylene bags and exposed to HPP for 9 different combinations of pressure (200 MPa, 300 MPa and 400 MPa) and time (5 min, 10 min and 15 min). Quantitative bacteriological analysis was carried out in order to determine the number of surviving C. jejuni cells. The obtained results showed that C. jejuni is relatively sensitive to high pressure treatment as compared to other food-borne pathogens. The loss of C. jejuni viability increased in a dose- and time-dependent manner. On the basis of the results, D-values were calculated. For reduction C. jejuni in poultry meat by 6 log units (6D-values), considered as sufficient for consumer protection, the application of 300 MPa for 8.73 min, or 400 MPa for 4.37 min is needed. The linear regression equations, which has been calculated on the basis of this study, allows to determine the degree of C. jejuni reduction in poultry meat for any selected duration of pressurization in a given pressure range.
Effect of oral administration of commercial gold nanocolloid on peripheral blood leukocytes in mice
Authors: Małaczewska J. 
Published: July 2015

Abstract
During the last few decades, owing to their unique properties, gold nanoparticles (AuNPs) have found numerous biomedical applications. Studies on rodents prove that AuNPs entering an organism easily reach the bloodstream and undergo wide tissue distribution. The presence of nanoparticles inside blood and bone marrow cells of exposed animals may implicate its influence on hematopoesis and the functions of peripheral blood leukocytes.
The aim of this study was to determine the effect of oral administration of commercial gold nanocolloid, recommended by the producer as a dietary supplement, on the percentage of lymphocyte populations and proliferative response, as well as the activity of phagocytes in the peripheral blood of mice. The colloid was given to the animals in three different doses (0.25, 2.5, 25 ppm), for three different time periods (7, 14, 28 days). Mice given nanoparticles showed increased activity of phagocytes and some changes in the lymphocyte phenotypes. The elevated activity of granulocytes and monocytes, in terms of both phagocytic and respiratory burst activity, was transient and noticed only after a short time of administration, which may indicate some adaptability of blood phagocytes to prolonged presence of gold nanoparticles in the body. However, phenotypic modifications among lymphocytes in the group of animals given the middle dose of colloid (i.e. increased percentage of B and CD4+CD8+ DP T cells) did not occur until after the 28-day administration, which in turn seems indicative of some immune dysregulation due to the prolonged contact with nanogold.

AbstractThe final weeks of pregnancy and period of increasing lactation abound with adaptive changes in the intensity of metabolic processes. Maintaining the homeostasis of an organism in prepartum and postpartum periods is the key condition in maintaining the health of the mother and the fetus/calf. The aim of the study was to analyze physiological changes in lipid metabolism in cows during the last month of first pregnancy and in the first two months of lactation, based on the expression of identified apolipoproteins and changes in selected parameters of the lipid metabolism in peripheral blood plasma. Statistically significant changes in the expression of identified apolipoproteins were observed for apolipoprotein A-1 precursor, apolipoprotein A-IV precursor, apolipoprotein E precursor and apolipoprotein J precursor. The lowest expression of the apolipoproteins was noted around parturition and higher expression was observed during the final weeks of pregnancy and during lactation. Tendencies of changes in the concentration of total cholesterol, HDL and LDL were similar in blood plasma from analyzed cows – in the last month of pregnancy a decrease was observed and subsequently an increase in the first two months of lactation was noted. In contrast to abrupt changes observed for total cholesterol, HDL and LDL, changes in concentration of triglycerides were not that extensive and during lactation this parameter was rather stable. Evaluation of changes in the analyzed parameters may contribute to a better understanding of the changes in lipid metabolism occurring in the body of pregnant and lactating young cows.
Pituitary adenylate cyclase-activating peptide-27 (PACAP-27) is co-stored with galanin, substance P and corticotropin releasing factor (CRF) in intrapancreatic ganglia of the sheep

Published: July 2015

Abstract
Pituitary adenylate cyclase activating polypeptide (PACAP) is a neuropeptide existing in two variant forms (of either 27 or 38 residues), widely present in numerous organs and evoking multiple effects both in the central and peripheral nervous systems. The present study was undertaken to evaluate the distribution pattern of PACAP-27 expression in the ovine pancreas. Using double immunohistochemical stainings co-localizations of PACAP-27 with galanin, SP or CRF were studied in intrapancreatic neurons. In intrapancreatic ganglia, immunoreactivty to PACAP-27 was found in 87.6 ± 5.4% of PGP 9.5-positive intrapancreatic neurons but not in intraganglionic nerve fibres. Numerous PACAP-27-immunoreactive nerve terminals were also observed between pancreatic acini and around small arterioles. No immunoreactivity to PACAP-27 was found in the endocrine pancreas. In 42.9 ± 6.2% of PACAP-27-immunoreactive intrapancreatic neurons the expression of galanin was also found. Statistically lower subpopulation (12.4 ± 4.0%) of intrapancreatic neurons exhibited simultaneously the immunoreactivity to PACAP-27 and SP. The expression of CRF was detected in the relatively smallest group (3.2 ± 1.4%) of PACAP-27-positive intrapancreatic neurons. The present results suggest that in the ovine pancreas PACAP-27 may play an important role as mediator of pancreatic functions. In PACAP-related pancreatic activities, a modulatory role of galanin, SP and to a lower extend of CRF is also likely.
Comparison of IgE test results with intradermal skin tests for dust mites and storage mites in atopic dogs

Published: July 2015

Abstract
Atopic dermatitis is one of the most frequent allergic diseases in dogs. There are many methods of treating its symptoms but specific immunotherapy has recently gained high popularity. Before the application of specific immunotherapy, it is necessary to identify the allergens provoking the reaction of hypersensitivity in the selected animal. This raises a question about the method of allergen identification the medical practitioner decides to use in order to obtain the most credible result. The authors of the present study decided to compare the results of intradermal allergic tests and the results of an IgE screening test carried out using the FcɛRIα receptor method. The aim of the study was to compare the results of both tests directed to dust and storage mites. The study proves that in case of the IgE screening tests (for a group of allergens), the sensitivity is quite high (85 to 90.69%) but the specificity of these tests is insufficient (25 to 50%). In case of antibodies for the selected mites the sensitivity and specificity was too low (65.1 to 89.4% for the sensitivity, with only 14.2 to 33.3% for the specificity). Only in case of D. petronyssinus the results were higher with the sensitivity calculated at 65.1% and the specificity at 80%. The IgE screening test carried out using the FcɛRIα receptor method is reliable only in case of screening test for mites and the intradermal allergic test remains the gold standard for allergy testing.

Published: July 2015

AbstractDeleterious response to road transport is an important problem in equine practice. It determines different physiological, immunological and metabolic changes which lead to increased susceptibility to several disorders such as pneumonia, diarrhea, colics, laminitis, injuries and rhabdomyolisis. The aim of our study was to look for possible relationships between transportation of female young and older horses over a long and short distance and an inflammatory state reflected by an increase of acute phase protein concentration, oxidative stress and muscle injury. The study was conducted on 24 cold-blooded female horses divided into four groups. Six fillies aged 6-18 months and six mares aged 10-12 years were transported over the distance of about 550 km, six fillies aged 6-18 months and six mares aged 10-12 years were transported over the distance of about 50 km. Plasma and serum were obtained from blood samples taken before transportation (T0), immediately after transportation (T1) and at an abattoir during slaughter (T2). In these samples fibrinogen, MDA, AST and CK were assessed. Fibrinogen increased in all studied groups especially in fillies after long distance transportation, where it reached 205±7.07 mg/dl before transportation, 625±35.35 mg/dl after transportation, and 790±14.14 mg/dl during slaughter. MDA concentrations rose after transportation and reached the maximal level during slaughter. CK activity was more elevated after short transportation in younger horses, whereas initial activity of AST was higher in older horses. We estimated that intensified responses from acute phase, oxidative stress and muscle injury parameters indicated an inflammatory state.

Abstract
The aim of the study was the preliminary development of laparoscopic transfer of embryos to the uterus in the pig, which can become the alternative for more invasive surgical methods. We proposed the original method of embryo transfer. Donors (n = 40) and recipients (n = 15) of embryos were sows of age of 6-8 months. The estrus cycle of both recipients and donors was routinely synchronized. The experimental animals were divided into two groups. In the first group (10 donors and 3 recipients) embryos were transplanted according to the method described earlier and in the second group (30 donors and 12 recipients) embryos were transplanted according to our own proposed method. As the control group, we used 16 sows after insemination (AI). In animals from both experimental groups pregnancy was diagnosed between 28-31 day after transplantation and in the control group between 28-31 day after insemination. All animals were observed during pregnancy and weaning period in pig farm. Embryos at the development stage of 2-4 cell were obtained surgically and cultured in vitro for 4 days. Obtained blastocysts were transferred to donors. The original set of catheters for blastocysts transfer to pig uterus was constructed. Three trocars were placed in abdominal cavity for inserting endoscope and 2 grasps for uterus stabilization. After uterus stabilization, the slide was inserted into abdomen which was used for putting the needle to puncture uterus. Through this needle catheter with embryos was inserted into the uterus cavity. Embryos were placed by injection into lumen of the one uterine horn. From 12 recipients pregnancy was diagnosed in 6 recipients. From 6 litters, 57 piglets were born. We weaned 41 piglets (71.9%). In our study we obtained 50% efficacy, with the mean number of 9.5 alive piglets in litter and 6.8 weaned piglets. The efficacy of developed method of laparoscopic transfer of porcine embryos allows it to be used in routine practice.

AbstractThis study was designed to assess alterations of hormone and cytokine levels associated with growth period during puberty in Honamlı goats which were identified as a new goat breed and had one of the highest meat production potential among the other goat breeds in Turkey. Honamlı goats are originated from native hair goats, so parallel studies of sampling and analyzing were conducted also in native hair goats which have moderate meat production. Blood serum samples of Honamlı (n=90) and native hair goats (n=90) were obtained from the pure herds in Korkuteli and Ka districts of Anatolia. Concentrations of growth hormone (GH), myostatin (MSTN), insulin-like growth factor (IGF), growth hormone releasing hormone (GHRH), growth hormone releasing peptide (GHRP), leptin, transforming growth factor-betal (TGF-β1) and vascular endothelial cell growth factor (VEGF) levels were measured by ELISA in each breed in the age groups of 4, 8 and 12 months. The present results indicate interesting correlations among the age groups and all the examined hormone and cytokine parameters exhibited significant (P<0.05 and P<0.001) differences. The parameters investigated were usually begun to increase after 4 months of age in the both breeds and sexes. Therefore, this paper supported the view that the beginning of hormonal alterations of goats could occur at 4th month of age. The results reported here emphasize the primary role played by GH, MSTN, IGF-1, leptin, GHRH, GHRP, TGF-βi and VEGF in the first year growth period of goats.

Abstract
Background: Hucul horses are the unique, genetically distinct breed of Carpathian Mountains. Even though they are recognized as primitive breed, many morphological differences between them and other primitive horses have been reported. Neither hematological nor blood biochemical studies in this breed have been conducted so far.
Objectives: The aim of this study was to establish the reference intervals for basic hematological and selected biochemical variables and to compare them with other breeds.
Material and Methods: Blood samples were collected from 168 Hucul horses and the analyses were performed using routine methods. Mainly nonparametric method was used to establish reference intervals.
Results: The following reference intervals have been established (rounded to two significant digits): RBC: 7.0-13×1012/l; HGB: 106.1-195.8 g/l; HCT: 0.3-0.6 l/l; MCV: 35-50 fl; MCH 11.9-17.1 pg; MCHC: 31.9-34.8 g/dl; WBC: 7.5-22×109/l, bands: 0-0.5×109/l; segmented neutrophils: 3.3-10×109/l; eosinophils: 0-1.1×109/l; basophils: 0-0.3×109/l; lymphocytes: 1.9-12×109/l; monocytes: 0-0.2×109/l; PLT 95-350×109/l; MPV 5.2-7.0; ALP: 98-425 U/l; AST: 220-470 U/l; GGT: 9.1-31 U/l; total bilirubin: 6.5-29 μmol/l; CPK: 120-640 U/l; triglycerides: 0.1-0.9 mmol/l; urea: 3.8-11 mmol/l; creatinine: 44 -140 μmol/l; serum amyloid A: 130-5200 μg/l.
Conclusions: Hematological and biochemical variables in Hucul horses were closer to hot-blooded then to cold-blooded and primitive horses or wild equidae. The reference intervals presented in this study pose clinically useful tool for evaluation of blood check-up in Hucul horses.

Authors: Ruść A. , Kamiński S. 
Published: July 2015

Abstract
The aim of this paper was to verify the hypothesis whether carriers of genetic defect Brachyspina occur in the Polish Holstein-Friesian Cattle. PCR method was used to screen 78 Polish Holstein-Friesian bulls. Eight bulls were identified as heterozygotes for 3,3 kb deletion in the FANCI gene – the mutation causing Brachyspina defect. All carriers were sons of 3 sires: Cleitus Jabot, Sandy-Valley Bolton ET and Coyne-Farms Dorcy ET which were descendants of the US sire Sweet Haven Tradition (HOUSAM 1682485). Systematic screening of young bulls having in the pedigree Barchyspina carrier is necessary to prevent spreading of the recessive mutation in the dairy cattle population in Poland.

Published: July 2015

Abstract
Nowadays all efforts in planing hull research are focused on resistance reduction for achieving the highest speed in fast planing crafts. Furthermore, many fruitful research projects have been carried out on marine coatings, planing equipment, and optimization of propeller and hull form, which revolutionized industry of high - speed crafts and made them an efficient survival vehicle in coastal areas and rivers. In this paper the hydrodynamic performance of planing hulls are investigated by means of a modified Savitsky model for both non-stepped and stepped bodies. Meanwhile, in order to meet this goal reasonably, effective geometrical parameters of planing hull are investigated and then operational hydrodynamic characteristics of the craft are predicted by using a computational program. Finally, the calculation results are verified by means of a CFD-analysis model.
Identification Of Damages Of Tribological Associations In Crankshaft And Piston Systems Of Two-Stroke Internal Combustion Engines Used As Main Propulsion In Sea-Going Vessels And Proposal Of Probabilistic Description Of Loads As Causes Of These Damages
Authors: Girtler Jerzy 
Published: July 2015

Abstract
The article discusses damages of essential tribological associations in crankshaft and piston systems of large power two-stroke engines used as main engines, which take place during transport tasks performed by those ships. Difficulties are named which make preventing those damages impossible, despite the fact that the technical state of engines of this type is identified with the aid of complex diagnostic systems making use of advanced computer technology. It is demonstrated that one of causes of the damages is the lack of research activities oriented on recognising random properties of the loads leading to those damages. A proposal is made for the loads acting at a given time t on tribological associations in crankshaft and piston systems of internal combustion engines used as main engines to be considered as random variables Qt. At the same time the loads examined within a given time interval tr ≤ t ≤ tz would be considered stochastic processes {Q(t): t ≥ 0}. Essential properties of the loads of the abovementioned tribological associations are named and explained by formulating hypotheses which need empirical verification. Interval estimation is proposed for estimating the expected value E(Qt) of the load Qt acting at time t. A relation is indicated between the mechanical load and the thermal load acting on tribological associations in the ship main engine crankshaft and piston system. A suggestion is formulated that a stochastic form of the relation between these types of load is to be searched for, rather than statistic relation, and a proposal is made to measure the intensity (strength) of the stochastic relation using the Czuprow’s convergence coefficient.
