    Opis:
    Poland as a country that actively participates in maintaining and opening peace in the world is exposed to various threats to the security of our country. The Polish government sends soldiers of the Polish Army to different regions of the world with the mission to create, maintain and create peace on all continents. Polish soldiers serve in peace-keeping, training and stabilisation missions all over the world under the auspices of the UN and NATO, and are exposed to various threats. One of these threats is the loss of personal data of Polish Armed Forces soldiers. Loss of these data affects the safety of our soldiers performing tasks outside the country and their families remaining in Poland, and thus affects the safety of our country.

    Opis:
    Interchanges are a key and the most complex element of a road infrastructure. The safety and functionality of interchanges determine the traffic conditions and safety of the entire road network. This applies particularly to motorways and expressways, for which they are the only way to access and exchange traffic. A big problem in Poland is the lack of comprehensive tools for designers at individual stages of the design process. This applies to guidelines or other documents regarding the location, choice of interchanges type and selection of design parameters. This does not provide sufficient material for designing safe and functional interchanges. This situation results in numerous hazards that occur on existing interchanges and errors that are still being made at all stages of the design process. Consequently, there is a risk of accidents in the area of interchanges, which often have serious consequences. The purpose of the research presented in the article is to identify main groups of hazards on the interchanges and to classify them based on field tests and audits of project documentation. The prepared classification uses the results of analyzing data on road accidents. As part of the research, a database was built that includes information on road accidents and traffic, as well as data on all existing interchanges on motorways and expressways in Poland. These data includes: interchange type, length of exit and entry lanes, total interchanges length, type of cross-section on main roads and ramps. The number and type of ramps occurring at a given interchange as well as the type of intersections, if any, were also taken into account. Based on the assessment, the level of safety was determined for individual types of interchanges. Then, the impact of selected road and traffic factors on safety was presented. The critical elements of interchanges are entries, exits, weaving sections and intersections. Assumptions were also adopted for the classification of identified hazards. A comprehensive safety assessment for interchanges allowed the development of assumptions for their design guidelines. On the basis of database exploration and field research, the main problems and hazards regarding the functioning of interchanges were identified.

    Opis:
    The night time, based on many world studies, generates an increased risk of serious accidents (with fatalities and serious injuries). This is especially true for accidents with pedestrians. Pedestrian crossings are very sensitive to the influence of the time of day in terms of pedestrian safety, elements of road infrastructure. This is visible on the example of Poland, where numerous accidents at crosswalks are recorded, characterized by high severity at night. Road infrastructure managers take corrective actions to improve this condition. An example of such work is the Road Safety Audit (RSA), initiated in 2016 by the Municipal Roads Management Board in Warsaw. The analyses carried out by the authors, among others, in the years 2016 - 2019, included pedestrian crossings without traffic lights located on roads managed by ZDM (Municipal Roads Authority) in twelve districts: Bemowo, Bielany, Mokotów, Ochota, Praga Południe, Praga Północ, Śródmieście, Targówek, Ursynów, Wawer, Włochy, Żoliborz. The assessment was carried out in terms of the correct lighting of these passages, traffic organization, geometry and environmental impact. The main aim of the article is to present a methodology for evaluating the technical condition of road lighting infrastructure on a large scale (e.g. district, city). The article discusses the general and detailed state of pedestrian safety in Poland against the background of research conducted in Warsaw. The procedure of inspection and assessment of the state of lighting of pedestrian crossings is described and selected results are presented. On the basis of a detailed analysis of the results of individual pedestrian crossings, the general condition of the tested crossings was assessed and recommendations were indicated. An attempt was made to assess the influence of pedestrian crossings lighting on the general state of road safety. A critical evaluation of the obtained effects was made. The utilitarian aim of the article is to apply the described methodology in other cities and to use the results of the conducted analyses to plan and implement road investments in the field of modernization of lighting at pedestrian crossings on a large scale.

    Opis:
    Integrating different modes of transport (road, rail, air and water) is important for port cities. To accommodate this need, new transport hubs must be built such as airports or sea ports. If ports are to grow, they must be accessible, a feature which is best achieved by building new roads, including fast roads. Poland must develop a network of fast roads that will provide good access to ports. What is equally important is to upgrade the network of national roads to complement fast roads. A key criterion in this case is to ensure that the roads are efficient to minimise time lost for road users and safe. With safety standards and safety management practices varying vastly across the EU, Directive 2008/96/EC of the European Parliament and of the Council was a way to ensure that countries follow procedures for assessing the impact of road projects on road safety and conduct road safety audits, road safety management and road safety inspections. The main goal of the research was to build mathematical models to combine road safety measures, i.e. injury density (DI) and accident density (DA), with road and traffic factors on longer sections, all based on risk analysis. The practical objective is to use these models to develop tools for assessing how new road projects will impact road safety. Because previous research on models to help estimate injuries (I) or injury density (DI) on long sections was scarce, the authors addressed that problem in their work. The idea goes back to how Poland is introducing procedures for assessing the effects of infrastructure on safety and developing a method to estimate accident indicators to support economic analysis for new roads, a solution applied in JASPERS. Another reason for the research was Poland’s insufficient and ineffective pool of road safety management tools in Poland. The paper presents analyses of several models which achieved satisfactory results. They are consistent with the work of other researchers and the outcomes of previous research conducted by the authors. The authors built the models based on a segmentation of national roads into sections from 10 to 50 km, making sure that they feature consistent cross-sections and average daily traffic volumes. Models were built based on the method described by Jamroz (Jamroz, 2011). Using the available road traffic volume data, each section was assigned variables defining geometric and traffic features. Based on studies conducted on road sections, the variables were either averaged over the entire length of the section or calculated as a percentage of the variable occurring over the entire length: related to traffic volume, roadside environment or cross section.

    Opis:
    Promoted by many cities to meet the commute needs of their residents (for work, education, etc.), urban rail transport is a spatially expanding system. The safety of rail passengers and road users is one of the most important factors to consider when designing the infrastructure and assessing the operation of the urban tram system. One of the unsolved issues in the functioning of tram transport are sections of tramways with large longitudinal slopes. The article presents an attempt to use risk management for assessing the operational safety of tramways located on road sections with large longitudinal gradients. This particular problem occurs on a tram route in Gdansk. It runs along a street (partly on an overpass) with a gradient above 5% and a small horizontal curve. Risk was assessed using TRANS-RISK, a risk management method. In the first stage, a risk analysis was carried out using the Bow-Tie methods and error trees. The main risks of serious accidents on the analysed section of the tramway were identified. Three sub-concepts were used to assess risk: individual, societal and collective. Although not generally used for assessments of urban transport infrastructure, the latter was found most useful for assessing the safety of the analysed infrastructure. The results of the analyses and assessments helped to formulate design and maintenance principles for tram infrastructure located on sections with steep gradients.
    Miejski transport szynowy wielu miastach stanowi istotny element systemu transportowego i jest przestrzennie rozwijającym się systemem zapewniająacym mieszkańcom codzienną obsługę transportową. Bezpieczeństwo pasażerów transportu szynowego i użytkowników dróg jest jednym z najważniejszych czynników, który należy uwzględnić w trakcie projektowania infrastruktury oraz w ocenie operacyjnej systemu miejskiego transportu tramwajowego. Jedną z nierozwiązanych kwestii funkcjonowania transportu tramwajowego są odcinki dróg tramwajowych o dużych pochyleniach podłużnych. W artykule przedstawiono próbę zastosowania metody zarządzania ryzkiem do oceny bezpieczeństwa funkcjonowania dróg tramwajowych na obiektach zlokalizowanych na odcinkach dróg o dużych pochyleniach podłużnych. Taki problem występuje na trasie tramwajowej w Gdańsku przebiegającej na ulicy (częściowo na estakadzie) o pochyleniu położonej powyżej 5% i małym łuku poziomym. Do oceny ryzyka zastosowano metodę zarządzania ryzykiem w transporcie TRANS-RISK. W pierwszym etapie przeprowadzono analizę ryzyka zagrożeń, korzystając z metod Bow-Tie i drzewa błedów zidentyfikowano główne zagrożenia poważnymi wypadkami na analizowanym odcinku drogi tramwajowej. Do oceny ryzyka zastosowano trzy podejścia oceniając ryzyko: indywidualne, społeczne i kolektywne. To ostatnie, nie używane w tego typu ocenach miejskiej infrastruktury transportowej, okazało się najbardziej przydatne do oceny bezpieczeństwa analizowanej infrastruktury. Wyniki przeprowadzonych analiz i ocen pozwoliły na sformułowanie zasad projektowania i utrzymania obiektów infrastruktury tramwajowej położonej na odcinkach o dużych pochyleniach.

    Opis:
    The objective of the research was to assess how selected factors influence road safety in Poland's poviats. To that end, an analysis was conducted of road accident determinants and effects in the poviats in the years 2010-2019. The time horizon fits in with Goal 3.6. of Agenda 2030, which is to halve the number of global deaths and injuries from road traffic accidents by 2020. The article presents the analysis results for the following determinants: the rate of car ownership by poviat, poviat spending on transport and length of the road network, and quality of road infrastructure. The research problem was to establish which of the poviats are closest to achieving Goal 3.6. of Agenda 2030 and how likely it is, and, as a consequence, which of the poviats should step up their road safety policies to align them to the targets set out in the Agenda. To identify groups of poviats sharing similar characteristics, they were grouped using the k-means method. Five groups of poviats were identified and analeffecysed for how their road safety indicators changed between 2010 and 2019. The results of the analysis show that the highest fatality reduction (-40%) was achieved by urban poviats with the highest per capita spending on transport. The same poviats, however, have the highest increases in serious injuries (+30%). The analyses show that Polish poviats are still far from achieving Goal 3.6 of Agenda 2030. The research results presented in the article are original for the poviat level.
    Celem prac badawczych była ocena wpływu wybranych czynników na poziom bezpieczeństwa ruchu drogowego w powiatach w Polsce. Dla osiągniecia tego celu wykonano analizę determinant i skutków wypadków drogowych w powiatach w latach 2010-2019. Przyjęty horyzont czasowy wpisuje się w cel 3.6. Agenda 2030, dotyczący zmniejszenia do 2020 roku o połowę liczby wszystkich ofiar rannych i śmiertelnych w wypadkach drogowych. W artykule przedstawiono wyniki analizy dla następujących determinant: stopień zmotoryzowania mieszkańców poszczególnych powiatów, wydatki budżetów powiatów na transport oraz długość sieci drogowej, uwzględniającej jakość infrastruktury drogowej. Problemem badawczym była odpowiedź na pytanie, które z powiatów były najbliżej realizacji celu 3.6. Agenda 2030 i jakie są w tym zakresie perspektywy, a w konsekwencji, dla jakich powiatów należy zintensyfikować działania naprawcze, zbliżające do celu Agenda. W celu identyfikacji grup powiatów o podobnej charakterystyce, przeprowadzono grupowanie metodą k-średnich. W rezultacie badania wyłoniono pięć grup powiatów, dla których wykonano analizy zmiany wskaźników bezpieczeństwa ruchu drogowego w latach 2010-2019. Wyniki analizy wskazują, że naj-większą redukcję liczby ofiar śmiertelnych (-40%) osiągnęła grupa miast na prawach powiatu, które ponoszą największe wydatki na transport w przeliczeniu na mieszkańca. Jednocześnie jednak w tych powiatach odnotowano najwyższy wzrost liczby ofiar ciężko rannych (+30%). Wyniki analiz wskazują, że polskie powiaty są nadal daleko od osiągnięcia celu 3.6 Agenda 2030. Oryginalność wyników badań przedstawionych w artykule odnosi się do badania na poziomie powiatów.

Zaprezentowano wyniki badań poligonowych i symulacyjnych funkcjonowania tego urządzenia, jako zakończenia barier (terminali) oraz jako osłon energochłonnych. Przeprowadzone analizy posłużyły do opracowania charakterystyki funkcjonowania analizowanych urządzeń w różnych warunkach terenowych (parametry projektowe w planie dla łącznicy) i ruchowych (prędkość i kąt uderzenia pojazdu). Na tej podstawie opracowano zasady projektowania i rekomendacje do stosowania tych urządzeń na drogach w Polsce.
    The paper presents an analysis of the functioning of selected energy absorbing devices on the road network in Poland and an assessment of the functioning of the SafeEnd energy absorbing device (U-15a). Then the results of field and simulation crash tests of the functioning of this device as the end of barriers (terminals) and as crash cushions are presented. The conducted analyses were used to develop the characteristics of the functioning of the analysed devices in various conditions (radius, design parameters in the plan for the ramps) and traffic conditions (speed and angle of vehicle impact). On this basis, design rules and recommendations for the use of these devices on roads in Poland were developed.

    Laparoscopic single access technique is a next step in development of minimally invasive surgery. The aim of the study was to present results of different laparoscopic single incision procedures and evaluate application of this technique. Material and methods. 102 patients (15 males and 87 females) who underwent laparoscopic single incision procedure from 15th October 2009 to 31st December 2012 were included in the study. Results. In the analyzed period we performed 72 cholecystectomies (70.6%), 8 left adrenalectomies (7.8%), 3 right adrenalectomies (2.9%), 7 splenectomies (6.9%), 5 spleen cysts unroofings (4.9%), 2 appendectomies (2%), 1 Nissen fundoplication procedure (1%), 1 removal of the adrenal cyst (1%) and 3 concomitant splenectomies and cholecystectomies (2.9%). There were 3 technical conversions to multiport laparoscopy, but no conversion to open technique. Complications were observed in 5 patients (4.9%). Average operation time was 79 min (SD=40), average hospitalization time 2.4 day (SD=1.4). Conclusions. Laparoscopic single incision technique is a safe method and can be used as a reasonable alternative to multiport laparoscopy in different minimally invasive procedures especially in young patients to whom an excellent cosmetic effect is particularly important.

    Opis:
    The aim of the study was to assess safety of elective laparoscopic cholecystectomy (LC) performed by residents that are undergoing training in general surgery. Material and methods. A retrospective analysis was conducted on 330 patients operated electively due to cholelithiasis. Patients with acute cholecystitis, choledocholithiasis, undergoing cholecystectomy as a part of more extensive operation and patients with gall-bladder cancer were excluded. Group 1 included patients operated by resident, group 2 – by specialist. Duration of operation, mean blood loss, number of major complications, number of conversions to the open technique and conversions of the operator, reoperations and length of hospital stay were analyzed. Results. Mean operative time overall was 81 min (25 – 170, SD±28.6) and 71 min (30-210, SD±29.1) in groups 1 and 2 respectively (p=0.00009). Mean blood loss in group 1 was 45±68.2 ml and in group 2 – 41±73.4 ml (p=0.23). Six major complications has occurred (1.81%) – 2 (2%) in group 1 and 4 (1.7%) in group 2. 18 cases (15.5%) of conversion of the operator occurred in group 1, and 6 cases (2.6%) of conversion of the operator happened in group 2. Average LOS was 1.9 days in group 1 and 2.3 days in group 2 (p=0.03979). Conlcusions. Elective LC performed by a supervised resident is a safe procedure. Tactics of “conversion of operator” allowed to prevent major complications. Longer LC by residents is natural during the learning curve. Modifications of residency program in the field of laparoscopy may increase its accessibility.

    The aim of the study was to verify the Mannheim Peritonitis Index (MPI) suitability to determine the probability of death among patients in Polish population operated due to peritonitis and to assess the possibility of using the Index to determine the risk of postoperative complications, relaparotomy and need for postoperative hospitalization in intensive care unit. Material and methods. Retrospective analysis covered 168 patients (M: F = 83: 85, mean age = 48.45 years, SD ± 22.2) treated for peritonitis. The MPI score was calculated for each patient. According to MPI results, patients were divided to the appropriate groups (<21, 21‑29, > 29) and within analyzed. The statistical analysis used Chi-square, Mann Withney U and Kolmogorov-Smirnov test. The best cut-off point for MPI was calculated on the basis of ROC analisys. Results. Mortality in the study group was 13.1%. In groups <21, 21‑29 and > 29 points according to MPI mortality was 1.75%, 28.13% and 50% respectively, the difference was statistically significant (p = 0.0124). Significant differences were observed in mortality depending on the diagnosis. Based on the ROC curve the cut-off point was identified as 32 with an accuracy of 85.9% and AUC = 81%. There has been a significant correlation between the MPI count and and the occurrence of: cardio-respiratory failure, acidosis, electrolyte imbalance, surgical wound complications, the need for treatment in the intensive care unit after surgery. Conclusions. The MPI is a simple and effective predictor of death among patients operated due to peritonitis. It can also provide assistance in assessing the risk of postoperative complications and the need for treatment in the intensive care unit.

    Opis:
    Laparoscopic surgery is becoming an approved technique in pancreatic surgery. It offers some advantages over an open approach due to shorter hospital stay and decreased complication rate. Regardless the technique the most significant problem of pancreatic surgery is postoperative pancreatic fistula. There are numerous methods attempted at reduction of its incidence. One of the possibilities is preoperative pancreatic duct stenting. It aims at decreasing the pressure in the pancreatic duct, which is supposed to facilitate pancreatic juice flow to the duodenum. The aim of the study was to determine the role of preoperative pancreatic duct stenting in pancreatic surgery. Material and methods. Nineteen patients undergoing laparoscopic pancreatic resection were enrolled into the study. Prior to the surgery, all of the patients were submitted for the Endoscopic Retrograde Choleangiopancreatography (ERCP) with pancreatic duct stenting. Following the subsequent laparoscopic pancreatic resection, all patients were monitored to detect the pancreatic fistula appearance. The pancreatic stent was removed 6‑8 weeks after the surgery. Results. With an exception of two patients, all other patients underwent successful ERCP with pancreatic duct stenting before the surgery. In one case the placement of the prosthesis failed due to a tortuous pancreatic duct. Five patients had an episode of acute pancreatitis including two severe courses as a complication of preoperative ERCP. One of the patient died due to severe GI bleeding 2 weeks after stenting. Among the procedures there were 15 distal pancreatectomies, two enucleations of the tumor localized in the uncinate process and in the body of the pancreas and one central pancreatectomy. The median time of surgery duration was 186 minutes (90‑300; ±56). No conversions to an open approach were necessary. Likewise, there was neither any major complications reported in a postoperative course nor incidence of pancreatic fistula in any of the patients undergoing surgery. Conclusions. Preoperative pancreatic duct stenting can decrease the incidence of pancreatic fistula. However, a number of serious complications exceed the potential benefit of this method.

    Opis:
    Due to the constant increase of public health awareness and widespread “cancerophobia”, the progressively larger number of incidentally diagnosed gall-bladder polyps became the source of anxiety, which leads patients and physicians to undertake therapeutic decisions, despite the absence of symptoms. The majority of gall-bladder polyps are benign. It is estimated that only 3 to 5% of polyps are malignant. Currently, there is lack of randomized control trials based on which the clear-cut criteria of qualification of patients with gall-bladder polyps for surgical procedure can be created. The aim of the study was to analyze gall-bladder polyps in patients who underwent laparoscopic cholecystectomy in the 2nd Department of General Surgery, Jagiellonian University Collegium Medicum. Material and methods. The retrospective study was conducted on 5369 patients who underwent laparoscopic cholecystectomy in the 2nd Department of General Surgery, Jagiellonian University Collegium Medicum with special attention to 152 (2.8%) patients in whom gall-bladder polyps were diagnosed preoperatively. Qualification criteria for surgery, surgical treatment results, and histopathological examination results were also analyzed. Results. Amongst the 5369 patients qualified for laparoscopic cholecystectomy, 152 (2.8%) were diagnosed with gall-bladder polyps during the preoperative ultrasound examinations. Postoperative histopathological examinations of 41 (27%) patients confirmed the presence of gall-bladder polyps. In 102 (67%) patients, only gall-stones were diagnosed without previously described polyps during the ultrasound examination. Analysis of the histopathological examination results revealed the presence of benign lesions in 35 (23.35%) patients. In 5 (3%) patients the presence of an adenoma, and in one (0.65%) the presence of adenocarcinoma were confirmed. Conclusions. Based on the conducted study and previous personal experience in the treatment of patients with gall-bladder polyps, we believe that due to the potential risk of neoplastic transformation, patients with polyps larger than 10 mm in diameter and polyps of proven rapid growth should be qualified for laparoscopic cholecystectomy. Indications for surgical treatment also seem reasonable in case of patients with present polyps and coexisting right upper quadrant pain, even though the above-mentioned is connected with gall-bladder deposits.

    Opis:
    Nowadays, high-precision machines require lightweight materials with very high strength. Ion implantation is used to improve the mechanical strength of the material. A further paper presents the influence of manganese and nitrogen ion implantation on changes of microhardness of the surface layer of cobalt alloy. Samples were analyzed with the SEM-EDS Phenom ProX microscope. Microhardness was assessed with the Vickers method, and the loads of 1 gf (0.00981 N) and 5 gf (0.049 N) was applied using a FM-800 from Future-Tech microhardness meter. At a load of 1 gf, the penetration depth of the implanted specimens was reached not exceeding 0.5 um. At this depth, all samples showed an increase in microhardness compared to the unimplanted sample. The highest increase in microhardness was achieved after implantation of Mn ions with dose D=1∙1017 Mn+/cm2 and energy E=175 keV. The increased load on the indenter to 5 gf reduced the microhardness differences between implanted and unimplanted samples.

    Opis:
    The reported prevalence of periampullary duodenal diverticula varies between 9 and 32.8%. The aim of the study was to evaluate the prevalence of periampullary diverticula in the studied population and establish whether their presence influence the risk of choledocholithiasis and the risk of Endoscopic Retrograde Cholangio Pancreatography (ERCP) related complications. Material and methods. The study group of 3788 patients who underwent ERCP between 1996 and 2016at the 2nd Department of General Surgery Jagiellonian University Medical College in Kraków were analyzed. The group comprised of 2464 women (mean age 61.7 years) and 1324 men (mean age 61.8 years). The patients were divided into two groups. Group A included patients in whom there were no periampullary diverticula detected. Group B included patients in whom the opening of the bile duct was in the vicinity of a duodenal diverticulum. Results. There were 3332 patients included in group A (2154 women and 1178 men) and 456 patients in group B (310 women and 146 men). The prevalence of periampullary duodenal diverticula in the analyzed group was 12.8%. The presence of stones or biliary sludge was diagnosed in 1542 patients (47.6%) in group A and 290 patients (68.1%) in group B. Recurrence of choledocholithiasis occurred in 4.5% of patients (70/1542) in group A and 10.3% of patients (30/290) in group B. Complications occurred in a total of 76 patients in group A (2.3%) and 22 patients in group B (4.8%). Conclusions. The presence of choledocholithiasis and the risk of ERCP related complications are significantly higher in the group with duodenal diverticula.

    Opis:
    Uchyłki okołobrodawkowe dwunastnicy występują w 9 do 32,8% populacji dorosłych. Celem pracy była ocena częstości występowania uchyłków okołobrodawkowych dwunastnicy w badanej grupie oraz określenie czy ich obecność wpływa na ryzyko wystąpienia kamicy przewodowej oraz liczba komplikacji okołozabiegowych w przebiegu endoskopowej wstecznej cholangiopankreatografii (EWCP). Materiał i metodyka. Do badania włączono 3788 pacjentów, u których wykonano EWCP w latach 1996 – 2016 w II Katedrze Chirurgii Ogólnej UJ CM w Krakowie. Badaną grupę stanowiły 2464 kobiety (średni wiek 61,7 lat) oraz 1324 mężczyzn (średni wiek 61,8 lat). Pacjenci zostali przydzieleni odpowiednio do jednej z dwóch grup. Grupę A stanowili chorzy, u których nie zdiagnozowano uchyłków okołobrodawkowych dwunastnicy. W grupie B znaleźli się chorzy, u których stwierdzono uchyłki dwunastnicy umiejscowione w pobliżu brodawki Vatera. Wyniki. Grupę A stanowiło 3332 pacjentów (w tym 2154 kobiety oraz 1178 mężczyzn), a grupę B 456 chorych (w tym 310 kobiet i 146 mężczyzn). Częstość występowania okołobrodawkowych uchyłków dwunastnicy w analizowanej grupie wynosiła 12,8%. Obecność złogów żółciowych wykazano u 1542 pacjentów (47,6%) w grupie A oraz u 290 chorych (68,1%) w grupie B. Nawrót kamicy przewodowej obserwowano w 4,5% (70/1542) przypadków z grupy A oraz w 10,3% (30/290) z grupy B. Komplikacje okołozabiegowe wystąpiły u 76 chorych z grupy A (2,3%) i 22 pacjentów z grupy B (4,8%). Wnioski. Częstość występowania kamicy przewodowej i ryzyko wystąpienia komplikacji po EWCP są znamiennie wyższe w grupie chorych, u których stwierdzono obecność uchyłku w pobliżu brodawki Vatera w porównaniu z pacjentami bez takiej diagnozy.

    Opis:
    Żywność zawiera potencjalnie mutagenne substancje, takie jak PhIP, heterocykliczna amina aromatyczna powstająca podczas obróbki cieplnej mięsa, jak również substancje mogące działać w sposób ochronny poprzez m.in. modulowanie odpowiedzi antyoksydacyjnej i przeciwzapalnej, jak np. kurkumina, która jest obecna w kurkumie i mieszance curry. Materiał i metody: W przedstawionych badaniach analizowano rolę PhIP i kurkuminy na uszkodzenia DNA w limfocytach izolowanych z krwi pacjentów z rakiem jelita grubego. Limfocyty osób z rakiem jelita grubego (10 pacjentów) oraz zdrowych (kontrola, 6 osób) traktowano PhIP i/lub kurkuminą, następnie poziom uszkodzeń DNA porównano metodą kometową. Wyniki: Wstępne wyniki sugerują, że limfocyty chorych na nowotwór jelita grubego mają większe podstawowe uszkodzenia DNA niż te od osób zdrowych. Uszkodzenia wywoływane PhIP są liniowo zależne od zastosowanej dawki i mogą być zredukowane w obecności kurkuminy (zwłaszcza w stężeniu do 5 μM). Wnioski: Dane wskazują, że kurkumina może wywierać działanie ochronne przed uszkodzeniami DNA indukowanymi mutagenem obecnym w żywności.
    Food contains substances that are potentially mutagens such as PhIP, heterocyclic aromatic amine, produced during heat treatment of meat, as well as substances that may act in protective manner, inter alia by modulating the antioxidant and anti-infl ammatory response, such as curcumin, which is present in turmeric and curry. Material and methods: This study investigated the effect of PhIP and curcumin on DNA damage in lymphocytes isolated from the blood of colorectal cancer patients. Lymphocytes from individuals diagnosed with colorectal cancer (N=10) and healthy individuals (control, N=6) were treated with PhIP or/and curcumin, followed by analysis of DNA damage using single cell gel electrophoresis (comet assay). Results: Preliminary results suggest that lymphocytes of patients with colorectal cancer have a greater baseline DNA damage than those from healthy individuals. PhIP-induced DNA damage is dose-dependent and can be reduced in the presence of curcumin, especially at low concentration (up to 5 μM). Conclusions: The data show that curcumin may exert a protective effect against DNA damage induced by mutagens present in food.
