AB  - Background/Aim. The deposition of hydroxyapatite (HAP) on the surface of titanium (Ti) alloys enhances bioactivity and osseointegration of the alloys which are widely used as implant materials in dentistry and orthopaedic surgery. However, the stability of HAP and subsequent biocompatibility of such alloys depends on the coating technique. The aim of this work was to test the cytotoxicity of a Ti alloy (Ti6Al4V), coated with HAP by a new plasma deposition method. Methods. The Ti6Al4V samples prepared as discs, 10 mm in diameter and 2 mm in thickness, were coated with HAP (one or both sides of the alloy) by an innovative atmospheric plasma jet method. The cytotoxicity of uncoated and HAP coated Ti6Al4V samples was evaluated by examining the morphological changes and viability of L929 fibroblasts in direct contact with the test materials. Adequate negative (polystyrene) and positive (nickel) control discs of the same size were used. The indirect cytotoxicity was determined by cultivating L929 cells with conditioning medium (CM), prepared as extract of the test samples incubated in the complete Roswell Park Memorial Institute (RPMI) 1640 medium for cell cultures. The cytotoxic effect was evaluated based on the degree of metabolic activity, necrosis, apoptosis and proliferation of L929 cells, using the appropriate assays. Results. Uncoated and one side HAP coated Ti6Al4V alloys were classified as non-cytotoxic according to the current ISO 10993-5 criteria, whereas two sides HAP coated Ti6Al4V alloy samples were slightly-moderate cytotoxic. The cytotoxicity manifested as the inhibition of metabolic activity and proliferation of L929 cells as well as the induction of their apoptosis and necrosis was significantly reduced by conditioning of HAP/Ti6Al4V alloys for 24 hours. The cytotoxic effect of HAP/Ti6Al4V CM only partly decreased in the presence of nifelate, a calcium (Ca) channel blocker, suggesting that Ca ions were not the only responsible cytotoxic agent. Conclusion. The original HAP coating procedure by atmospheric plasma spraying with high energy input enables the production of the stable adhesive coatings on Ti6Al4V alloys. Their cytotoxicity, which depends on the quantity of HAP coating layer, could be significantly reduced up to the non-cytotoxic level by prior conditioning of the alloys in culture medium. Such a procedure, which removes leachable toxic components, could be useful before implantation of HAP coated alloys in vivo.

Oblaganje površine legura titana (Ti) hidroksiapatitom (HAP) poboljšava bioaktivnost i oseointegraciju Ti legura, koje se široko koriste kao implantacioni materijali u stomatologiji i ortopediji. Međutim, stabilnost HAP prevlake i biokompatibilnost takvih legura zavise od primenjene tehnike oblaganja. Cilj ovog rada je bio da se ispita citotoksičnost Ti6Al4V legure obložene sa HAP pomoću plazme korišćenjem originalne metode. Metode. Uzorci Ti6Al4V legure u obliku diska, prečnika 10 mm, debljine 2 mm su presvučeni sa HAP (jednostrano ili obostrano) mlazom atmosferske plazme. Citotoksičnost neobložene i HAP-om obloženih Ti6Al4V legura je ispitivana na osnovu morfoloških karakteristika i vijabilnosti L929 fibroblasta u direktnom kontaktu ćelija sa test materijalima. Odgovarajuća negativna kontrola (polistirenski diskovi) i pozitivna kontrola (diskovi od nikla) istih veličina kao i diskovi Ti6Al4V legura su takođe uključeni u eksperimente. Indirektna citotoksičnost je procenjivana nakon kultivisanja L929 ćelija sa kondicioniranim medijumom (CM), koji je predstavljao ekstrakt testiranih uzoraka inkubiranih u kompletnom Roswel Park Memorial Institute (RPMI) 1640 medijumu za ćelijske kulture. Citotoksični efekat CM je procenjivan na osnovu stepena metaboličke aktivnosti, nekroze, apoptoze i proliferacije L929 ćelija, korišćenjem adekvatnih testova. Rezultati. Neobložena Ti6Al4V legura i Ti6Al4V legura obložena jednostrano sa HAP su okarakterisane kao necitotoksične na osnovu ISO 10993-5 kriterijuma, dok je Ti6Al4V legura obložena sa HAP obostrano pokazivala blagu do umerenu citotoksičnost. Citotoksičnost, koja se manifestovala smanjenjem metaboličke aktivnosti i proliferacije L929 ćelija kao i indukcijom njihove apoptoze i nekroze, je bila značajno smanjena ako su uzorci HAP-om presvučenih legura kondicionirani u medijumu u toku 24 časa. Citotoksičnost CM pripremljenih od Ti6Al4V legura obloženih sa HAP je bila samo delimično smanjena u prisustvu nifelata, blokatora kalcijumovih (Ca) kanala, što ukazuje da Ca joni nisu jedini citotoksični faktor. Zaključak. Originalna metoda oblaganja Ti6Al4V legure sa HAP pomoću atmosferske plazme u obliku spreja visoke energije omogućava stabilnu adheziju prevlake. Citotoksičnost ovako obrađene legure, koja zavisi od količine nanetog HAP, se može znatno smanjiti do necitotoksičnog nivoa prethodnim kondicioniranjem u medijumu. Ova procedura, kojom se uklanjaju rastvorljive toksične komponente, može biti korisna pre in vivo implantacije legura obloženih sa HAP.

AB  - The aim of this study was to investigate the biocompatibility of nanostructured materials based on highly active calcium silicates mixed with different radiocontrast agents in comparison to MTA(+) using in vitro and in vivo model. Morphology of materials' samples was analyzed using SEM while the phase compositions were identified by XRD. pH values of materials' suspensions were conducted by pH-meter. The cytotoxicity of materials' solutions was tested by MTT test (100, 50, 25 and 12.5mg/ml). LDH and H-3-thymidine assay were utilized for biocompatibility investigations of materials' eluates (24h, 7 day and 21 day). Eighteen Guinea pigs were used for intramuscular implantation, as teflon tubes with freshly prepared materials were placed into intramuscular pockets. All samples were composed of round and needle-like particles equally distributed with Ca/Si ratio 2.7 at%, with the presence of hydrated calcium silicate phases. The pH values of ALBO-MPCA(1) and ALBO-MPCA(2) were high alkaline, while in case of MTA(+) they were lower and continuously declined (p lt 0.05). Investigated materials didn't exhibit dose-dependent effect on metabolic activity of L929 cells (p>0.05). Significant differences in the percentage of cytotoxicity between diluted and undiluted extracts between all tested materials after 24h and 7 day were noticed (p lt 0.05). Increase in L929 cells proliferation was noticed in case of undiluted eluates of ALBO-MPCA(1) and ALBO-MPCA(2) after 7 day (p lt 0.05). There were no statistically significant differences in the intensity of inflammatory response between investigated materials and control group after 60 day (p>0.05). Evaluation of biocompatibility of both ALBO-MPCA(1) and ALBO-MPCA(2) indicate their potential clinical use. [GRAPHICS] .

AB  - Introduction: The aim of this article was to analyze biocompatibility and bioactivity of new endodontic materials on the basis of nanosynthesized calcium silicates (ALBO-MPCA(1) and ALBO-MPCA(2)) combined with different radiopacifiers in comparison with MTA(+). Methods: Morphology of the samples was studied by scanning electron microscopy, and the pH and ion release analysis were also assessed. Biocompatibility of materials' eluates (24-hour, 7-day, and 21-day) was conducted by using MIT test. Twelve New Zealand white rabbits were used for intraosseous implantation. Four calvarial defects per animal were created and filled with freshly prepared investigated materials. Results: Samples mostly consisted of agglomerates built up from nanoparticles, preferably spherical and rod-like. There was no significant difference among pH values of materials' eluates after 24 hours (P>.05). The amount of calcium and aluminum ion release decreased, whereas the amount of magnesium and bismuth (ALBO-MPCAl, MTA(+)) and barium (ALBO-MPCA(2)) increased during 21-day period. The metabolic activity of cells increased after the extraction time, except in case of undiluted elutes of ALBO-MPCA(2) and ALBO-MPCAI (21-day). Histologic analysis of the samples revealed newly formed bone tissue with moderate inflammation for all investigated materials, which subsided during 90-day period to mild. Both MIA(+) and ALBO-MPCAI were in direct contact with the newly formed bone tissue. After 90 days, statistically significant difference in hard tissue formation was observed in comparison of MIA(+) and ALBO-MPCki with control group (P  lt .05). Conclusions: Experimental materials ALBOMPCA, and ALBO-MPCA(2) possess both biocompatibility and bioactivity. Because ALBO-MPCAA provokes favorable biological response, it is especially good candidate for further clinical investigations.

AB  - Background/Aim: Lately, fully innovative sol-gel method with high-temperature self-propagating reaction was used for the synthesis of new nanostructured endodontic materials, in combination with different radiopacifiers: bismuth (ALBO-MPCA1) and barium (ALBO-MPCA2). The aim of this study was to investigate the biocompatibility of nanostructured endodontic materials based on highly active calcium silicates and mixed with different radiopacifiers in comparison to MTA+ using human stem cells from the apical papilla- SCAP cells. Material and Methods: Morphology of the samples was studied by SEM. The tested materials were mixed with distilled water in a ratio 2:1 (m/m). Fifteen minutes after the preparation, samples were used in the experiment. The biocompatibility of fresh materials, after 3h and 7 days, was tested using 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide- MTT test. Results: Samples mostly consisted of spherical and rode-like. The relative viability of cells increased following the exposure time. Conclusion: The biocompatibility of synthesized materials is comparable to the control material MTA+, and therefore these materials can be recommended for further clinical studies.

AB  - Background/Aim. Morbidity and mortality of continous ambulatory peritoneal dialysis (CAPD) patients is still very high. The aim of the study was to evaluate the effects of peritoneal dialysis (PD) solutions (standard vs biocompatible) on long-term patients' and the techique survival. Methods. A total of 42 stable patients on CAPD participated in this crosssectional study. They were prospectively followed-up during the twelve years. Patients with severe anemia (Hb  lt  10 g/L) and malignant disease ware excluded. Twenty one (50%) patients were treated with the standard PD solutions (CAPDP- 1) while the other 21 (50%) were treated with biocompatible PD solutions [(lower level of glucose degradation products, lower concentration of Ca2+ and neutral pH (CAPDP-2)]. All patients were analyzed for a presence of vascular calcification, nutrition status, and parameters of inflammation after 2.5 ± 0.6 years of starting CAPD, and these variables considered in the analysis as risk factors. Results. The patients from the group CAPDP-2 compared to those from the group CAPDP-1 had lower level of high-sensitivity C-reactive protein (hs-CRP) (p = 0.003), and better nutritional status as confirmed by the mid-arm circumference (p = 0.015), and midarm muscle circumference (p = 0.002) and subjective global assessment (p = 0.000). Also, they had lower vascular calcifications as confirmed by intima media thickness (IMT) (p = 0.003), degree of carotid narrowing (p = 0.001) and calcified plaques of common carotid arteries (CCA) (p = 0.008). Kaplan- Meier analysis confirmed better survival of patients from the group CAPDP-2 than those from the group CAPDP-1 (1-, 5-, and 10-year patients survival rate was: 100%, 61.9% and 14.3% for the group CAPDP-1, and 100%, 85.7%, and 52.4% for the group CAPDP-2, respectively; p = 0.0345). The 1-, 5-, and 10-year technique survival rate was: 100%, 71.4%, and 38.1% for the group CAPDP-1, and 100%, 85.7%, and 76.2% for the group CAPDP-2, respectively; (p = 0.0719). Duration of dialysis, serum triglyceride and cardiovascular score (quantitative scoring system consisting of: ejection fraction (EF) of left ventricle  lt  50%; IMT > 1 mm; carotid narrowing degree > 50%, presence of carotid plaques in both common carotide, ischaemic heart disease, cerebrovascular event and peripheral vascular disease with or without amputation) were independent predictors of overall patient survival. Duration of dialysis was only independent predictor of overall technique survival. Conclusion. Although patients treated with biocompatible solutions showed significantly better survival, the role of biocompatibility of CAPD solutions in patients and technique survival have to be confirmed. Namely, multivariate analysis confirmed that duration of dialysis, serum triglyceride and cardiovascular score significantly predicted overall CAPD patients survival, while only duration of dialysis was found to be independent predictor of overall technique survival.
AB  - Uvod/Cilj. Morbiditet i mortalitet bolesnika na kontinuiranoj ambulantnoj peritoneumskoj dijalizi (KAPD) i dalje je neprihvatljivo visok. Cilj rada bio je da se proceni uticaj vrste dijaliznih rasvora (bioinkompatibilni vs biokompatibilni) na višegodišnje preživljavanje bolesnika i same tehnike KAPD. Metode. Ovom studijom preseka sa delimično prospektivnim praćenjem ishoda lečenja obuhvaćeno je ukupno 42 nasumice izabrana, stabilna bolesnika (26 muškaraca i 16 žena) lečena primenom metode KAPD tokom poslednjih 12 godina. Isključeni su bolesnici sa teškom anemijom (Hb  lt 10 g/L) i malignom bolešću. Pri tome, 21 (50%) bolesnika kontinuirano je lečeno bioinkompatibilnim rastvorom za KAPD (kiseli standardni rastvor - ANDY-disc; grupa KAPDB-1), dok je preostalih 21 bolesnik sve vreme bilo na biokompatibilnijem rastvoru za KAPD (neutralni rastvor sa znatno manjom koncentracijom degradacionih produkata glukoze, 1.25 mmol/L Ca i 40 mmol/L laktata - Gambrosol Trio; grupa KAPDB-2). Svim bolesnicima određeni su odabrani parametri hronične inflamacije, malnutricije i ateroskleroze zajedno sa transportnim karakteristikama peritoneumske membrane i rezidualnom bubrežnom funkcijom nakon 2,5 ± 0,6 god od započinjanja KAPD. Svi dobijeni rezultati analizirani su kao potencijalni faktori rizika. Rezultati. Grupa KAPDB-2 u odnosu na KAPDB-1 imala je statistički značajno niže vrednosti serumskog hs-CRP (p = 0,003) i bolje parametre nutritivnog statusa izražene kroz obim nadlaktice (p = 0,015), obim mišića nadlaktice (p = 0,002) i subjektivnu globalnu procenu (p = 0,000) kao i u manjoj meri prisutnu aterosklerozu potvrđeno debljinom intimomedijalnog kompleksa (IMT) (p = 0,003), stepenom suženja karotida (p = 0,001) i prisustvom kalcifikovanih ateromatoznih plakova na karotidnim arterijama (p = 0,008). Kaplan-Meier-ova kriva preživljavanja potvrdila je značajno duže preživljavanje bolesnika u grupi KAPD-2 u odnosu na KAPDB-1 (1-, 5-, i 10-godišnje preživljavanje bolesnika iznosilo je redom: 100%, 61.9% i 14.3% u KAPDB-1, a 100%, 85,7% i 52,4% u KAPDB-2 grupi; p = 0,0345). Stopa 1-, 5-, i 10-godišnjeg preživljavanja metode iznosila je: 100%, 71,4% i 38,1% u KAPDB-1, a 100%, 85,7% i 76,2% u KAPDB-2 grupi (p = 0,0719). Kao nezavisni prediktori opšteg preživljavanja bolesnika na KAPD izdvojili su se: dijalizni staž, nivo serumskih triglicerida i skor kardiovaskularnog morbiditeta (kvantitativni sistem zbrajanja prisutnih sledećih parametara: ejekciona frakcija (EF) leve komore  lt  50%; IMT >1 mm; suženje lumena karotida > 50%; kalcifikovani ateromatozni plakovi na obe karotide; ishemijska bolest srca; cerebrovaskularni događaj i periferna vaskularna bolest sa ili bez gangrene). Kao nezavisan prediktor preživljavanja metode izdvojio se jedino dijalizni staž. Zaključak. Iako su bolesnici na KAPD sa biokompatibilnijim rastvorima pokazali statistički značajno bolje preživljavanje, ne možemo tvrditi da bioinkompatibilnost dijaliznih rastvora predstavlja značajan faktor rizika od preživljavanja bolesnika i same metode lečenja. Naime, multivarijantnom analizom kao prediktori opšteg preživljavanja bolesnika izdvojili su se samo dijalizni staž, nivo serumskih triglicerida i skor kardiovaskularnog morbiditeta, dok se za očuvanje peritoneumske membrane kao nezavisan faktor rizika prikazao samo dijalizni staž.

AB  - Background: Chronic inflammation, malnutrition and atherosclerosis (MIA syndrome) are important predictors of high mortality in continuous ambulatory peritoneal dialysis (CAPD) patients. We aimed to evaluate the effects of PD solutions (standard vs. biocompatible) on some parameters of MIA syndrome in patients undergoing CAPD. Methods: 42 stable patients who were on CAPD at least 2.5 years participated in this cross-sectional study. Patients who had severe anemia (Hb  lt  10 g/l), immunomodulatory therapy, peritonitis or any inflammatory conditions for at least 3 months before the analysis, malignant disease and acute exacerbation of heart failure, were excluded. 21 (50%) patients were treated with standard PD solutions (CAPDP-1), while the remaining 21(50% of patients) were treated with biocompatible PD solutions (neutral solutions with lower level of glucose degradation products and lower concentration of calcium, CAPDP-2). All patients underwent echocardiography and B-mode ultrasonography of common carotid arteries together with assessments of nutrition status and parameters of systemic and local inflammation. Results: There were no significant differences between the groups concerning age, gender, underlying disease, residual renal function, peritoneal transport characteristics, comorbidity or therapy applied. Patients from group CAPDP-2 had a significantly lower serum level of hs-CRP (3.7 +/- 2.6 mg/l vs. 6.3 +/- 4.5 mg/l; p = 0.023) and significantly better nutritional status confirmed by mid-arm circumference (p = 0.015), mid-arm muscle circumference (p = 0.002) and subjective global assessment (14.28% of patients in CAPDP-2 vs. 71% of patients in CAPDP-1 were malnourished; p = 0.000). Group CAPD-2 had less frequent left ventricular hypertrophy (p = 0.039), thinner intima-media thickness (p = 0.005), smaller carotid narrowing (p = 0.000) and fewer calcified plaques of common carotide arteries (p = 0.003). No significant difference between the CAPDP groups was observed in serum and effluent levels of inflammatory cytokines (IL-1, IL-6 and TNF-alpha) and CA-125 effluent level. Logistic regression analysis did not confirm that biocompatibility of PD solutions was an independent predictor of any parameter of MIA syndrome. Conclusions: According to the present study and logistic regression analysis, the effect of biocompatible CAPD solutions on parameters of malnutrition, inflammation and atherosclerosis have to be confirmed by well-designed and controlled studies in a higher number of patients.

AB  - Aim To analyse phenotypic characteristics of antigen-presenting cells (APC), isolated from human periapical lesions by flow cytometry and immunocytochemistry. Methodology Sixteen periapical lesions were digested for 15 min with 0.05% collagenase. Mononuclear cells, separated from other inflammatory cells by density centrifugation, were processed for flow cytometry and/or immunocytochemistry. Single and double immunostainings were performed using monoclonal antibodies specific for human CD45, CD3, CD19, CD14, HLA-DR, CD1a, CD83 and CD123. Results Antigen-presenting cells (HLA-DR+ cells) represented 32.9 +/- 17.8% of total mononuclear cells. Amongst them, B cells (HLA-DR+ CD19(+)) were the predominant APC population, followed by activated macrophages (HLA-DR+ CD14(+)), dendritic cells (DC) (HLA-DR+ CD14(-) CD19(-) CD3(-)) and activated T cells (HLA-DR+ CD3(+)). Based on the predominance of T cells (CD3(+)) or B cells and plasma cells (CD19(+) and CD19(lo), respectively) amongst mononuclear cell infiltrates, lesions were divided into T- and B-types. The percentage of DC in T-type lesions (27.1 +/- 6.8% of total HLA-DR+ cells) was higher, compared with B-type lesions (10.3 +/- 5.2%) (P  lt  0.01). Within the DC population, the percentages of CD1a (Langerhans cell type) and CD123 (probably plasmacytoid DC type) did not differ significantly between the groups (P > 0.05). However, the percentage of mature DC (CD83(+)) was significantly higher in T-type periapical lesions (P  lt  0.05). Conclusion Flow cytometry and immunocytochemistry are suitable methods for phenotypic analysis of APC after their isolation from human periapical lesions. APC, that were phenotypically heterogeneous, constituted a significant component of infiltrating cells. Lesions with the predominance of T cells were characterized by a higher proportion of mature DC (HLA-DR(+)CD83(+) cells) than lesions with predominance of B cells/plasma cells.

abstract = "Aim To analyse phenotypic characteristics of antigen-presenting cells (APC), isolated from human periapical lesions by flow cytometry and immunocytochemistry. Methodology Sixteen periapical lesions were digested for 15 min with 0.05% collagenase. Mononuclear cells, separated from other inflammatory cells by density centrifugation, were processed for flow cytometry and/or immunocytochemistry. Single and double immunostainings were performed using monoclonal antibodies specific for human CD45, CD3, CD19, CD14, HLA-DR, CD1a, CD83 and CD123. Results Antigen-presenting cells (HLA-DR+ cells) represented 32.9 +/- 17.8% of total mononuclear cells. Amongst them, B cells (HLA-DR+ CD19(+)) were the predominant APC population, followed by activated macrophages (HLA-DR+ CD14(+)), dendritic cells (DC) (HLA-DR+ CD14(-) CD19(-) CD3(-)) and activated T cells (HLA-DR+ CD3(+)). Based on the predominance of T cells (CD3(+)) or B cells and plasma cells (CD19(+) and CD19(lo), respectively) amongst mononuclear cell infiltrates, lesions were divided into T- and B-types. The percentage of DC in T-type lesions (27.1 +/- 6.8% of total HLA-DR+ cells) was higher, compared with B-type lesions (10.3 +/- 5.2%) (P  lt  0.01). Within the DC population, the percentages of CD1a (Langerhans cell type) and CD123 (probably plasmacytoid DC type) did not differ significantly between the groups (P > 0.05). However, the percentage of mature DC (CD83(+)) was significantly higher in T-type periapical lesions (P  lt  0.05). Conclusion Flow cytometry and immunocytochemistry are suitable methods for phenotypic analysis of APC after their isolation from human periapical lesions. APC, that were phenotypically heterogeneous, constituted a significant component of infiltrating cells. Lesions with the predominance of T cells were characterized by a higher proportion of mature DC (HLA-DR(+)CD83(+) cells) than lesions with predominance of B cells/plasma cells.",
