Tannic acid-stabilized pericardium tissue: IR spectroscopy, atomic force microscopy, and dielectric spectroscopy investigations.

Infrared (IR) spectroscopy, atomic force microscopy (AFM), and dielectric spectroscopy methods were employed to study structural and dynamic changes in the tannic acid (TA)-stabilized pericardium tissue. Chemically stabilized pericardium tissue is widely used in construction of the tissue derived bioprostheses. IR spectra recorded in the range 400-4000 cm-1 allowed us to recognize different types of TA-collagen interactions. Formation of hydrogen bonds between amine as well as amide NH groups from collagen and hydroxyl groups of TA was analyzed. The AFM imaging showed that the stabilization procedure with TA introduces considerable changes in both surface topography and thickness of collagen fibrils as well as in fibril arrangement on the tissue surface. It was found, that these structural changes have an impact on the dielectric behavior of the TA-stabilized tissue. The dielectric spectra for the native and TA-stabilized tissues were measured in the frequency and temperature ranges of 10(-1) -10(7) Hz and 120-270 K, respectively. The dielectric spectra revealed the relaxation process due to orientation of bound water supplemented by the fluctuation of collagen polar side groups. At the temperatures above approximately 210 K, the relaxation due to ion migration process was observed. It was found that both relaxation processes were influenced by the TA-collagen interaction.

Atomic force microscopy and FT-IR spectroscopy investigations of human heart valves.

Human aortic, mitral, tricuspid and pulmonary heart valves were investigated by the contact mode atomic force microscopy (AFM) in air, and using FT-IR spectroscopy in the frequency range 950-4000 cm(-1). Heart valves were collected post mortem from 65-78 years old patients who died from non-cardiac diseases. All of the examined valves showed considerable heterogeneity in the surface topography of collagen fibrils as well as in their organization on the tissue surface. The AFM images revealed areas with significantly different spatial organization of the collagen fibril bundles. We observed zones with multidirectional, stacked collagen fibrils as well as areas of thin fibrils packed regularly, densely and "in phase". The majority of the collagen fibrils reproduced the typical transverse D-banding pattern, with the band interval varying in rather wide range of 70-90 nm. Using AFM imaging, objects that correspond to some pathological states of heart valves at their early stages, i.e. some forms of mineral deposits, were observed. The FT-IR spectra allowed us to recognize main components, i.e. collagen and elastin, in di.erent layers (ventricularis, fibrosa) of the valve leaflets as well as they gave also support for the presence of mineral deposits on the valve surface. The presented results showed, that the AFM imaging and FT-IR spectroscopy can be applied as a complementary methods for structural characterization of heart valves at the molecular and supramolecular levels.

Atomic force microscopy investigation of chemically stabilized pericardium tissue.

Native and chemically stabilized porcine pericardium tissue was imaged by the contact mode atomic force microscopy (AFM), in air. Chemically stabilized pericardium is used as a tissue-derived biomaterial in various fields of the reconstructive and replacement surgery. Collagen type I is the main component of the fibrous layer of the pericardium tissue. In this study, the surface topography of collagen fibrils in their native state in tissue and after chemical stabilization with different cross-linking reagents: glutaraldehyde (GA), dimethyl suberimidate (DMS) and tannic acid (TA) was investigated. It has been found that chemical stabilization causes considerable changes in the surface topography of collagen fibrils as well as in the spatial organization of the fibrils within the tissue. The observed changes in the D-spacing pattern of the collagen fibril correspond to the formation of intrafibrilar cross-links, whereas formation of interfibrilar cross-links is mainly responsible for the observed tangled spatial arrangement of fibrils and crimp structure of the tissue surface. The crimp structure was distinctly seen for the GA cross-linked tissue. Surface heterogeneity of the cross-linking process was observed for the DMS-stabilized tissue. SDS-PAGE electrophoresis was performed in order to evaluate the stabilization effect of the tissues treated with the cross-linking reagents. It has been found that stabilization with DMS, GA or TA enhances significantly the tissue resistance to SDS/NaCl extraction. The relation between the tissue stability and changes in the topography of the tissue surface was interpreted in terms of different nature of cross-links formed by DMS, GA and TA with collagen.

Structural changes in pericardium tissue modified with tannic acid.

INTRODUCTION: Structural modification of proteins, mainly collagen in connective tissues, is important in the manufacture of tissue-derived biomaterials. Natural compounds like genipin or tannic acid (TA) have been proposed instead of glutaraldehyde which shows cytotoxic effects on the processed tissue. Furthermore, calcification of glutaraldehyde-treated tissue limits the functional lifetime of bioprostheses. TA is known to form numerous hydrogen bonds with proteins. The purpose of our study was to investigate structural changes in porcine pericardium upon chemical modification with tannic acid. METHODS: Porcine pericardium tissue (PP) was soaked in 2% TA for 4, 24 or 48 hours. Changes in tissue structure were studied using electrophoresis (SDS-PAGE) and histological examination. Structural stability of PP tissue was evaluated by SDS/NaCl extraction method and enzymatic digestion with pancreatin. RESULTS: TA-modification of PP caused a time-dependent decrease in the number of peptides extracted from tissue. Microscopic studies revealed no significant morphological differences between native and TA-modified tissues, except for the native pancreatin-digested tissue where lack of both cells and low molecular peptides was observed. CONCLUSION: Modification of PP with TA causes the structural changes leading to an increase in the tissue resistance to SDS/NaCl extraction and enzymatic digestion, providing experimental evidence for the higher structural stability of TA-treated tissue.

Ionic diffusion and space charge polarization in structural characterization of biological tissues.

In this study, a new approach to the analysis of the low-frequency (1-10(7) Hz) dielectric spectra of biological tissue, has been described. The experimental results are interpreted in terms of ionic diffusion and space charge polarization according to Sawada's theory. The new presentation of dielectric spectra, i.e. ([Formula: see text]) [Formula: see text] has been used. This method results in peaks which are narrower and better resolved than both the measured loss peaks and an alternative loss quantity [Formula: see text]. The presented method and Sawada's expression have been applied to the analysis of changes in the spatial molecular structure of a collagen fibril network in pericardium tissue exposed to glutaraldehyde (GA), with respect to the native tissue. The diffusion coefficient of ions was estimated on the basis of a dielectric dispersion measurement for an aqueous NaCl solution with a well-calibrated distance between the electrodes. The fitting procedure of a theoretical function to the experimental data allowed us to determine three diffusive relaxation regions with three structural distance parameters d(s), describing the spatial arrangement of collagen fibrils in pericardium tissue. It has been found that a significant decrease in the structural distance d(s) from 87 nm to 45 nm may correspond to a reduction in the interfibrillar distance within GA cross-linked tissue.

Photoconductivity of synthetic dopa-melanin polymer.

The photoconductivity effect in synthetic dopa-melanin polymer with relation to the charge hopping conduction has been investigated. Measurements of the rise and decay of photocurrents upon visible radiation (400-800 nm) and at temperatures of 293-326 K allowed the determination of the major trapping levels as follows: 56, 35 and 26 kJ/mol. Spectral response of the steady-state photocurrent in the range 367-1100 nm showed significant departures from the absorption spectrum of melanin. The high concentration of traps or recombination centers can explain the long time-constants calculated from the photocurrent rise and decay curves. The results obtained can support the postulated earlier polarons and hopping model of conductivity in synthetic dopa-melanin.

Von Willebrand factor, fibrinogen and other risk factors of thrombosis in patients with a history of cerebrovascular ischemic stroke and their children.

BACKGROUND AND AIM: Von Willebrand factor (vWF) and fibrinogen (Fb) have recently emerged as plausible familial determinants of atherothrombosis. We investigated whether the vWF and Fb levels in patients with ischemic cerebrovascular stroke (ICS) correlate with those in their children. METHODS AND RESULTS: The study group consisted of 28 families (56 parents and 34 children) with one parent who had suffered an ICS at least three months before the study. All of the ICS patients had hyperlipoproteinemia and most arterial hypertension. The control group consisted of 15 families (30 parents and 20 children). The age of the parents and children did not exceed 55 and 16 years. The ICS parents had significantly higher vWF, Fb and protein C (PC) levels than the controls (vWF--fathers: 121.0 +/- 42.5% vs 79.2 +/- 23.4%; vWF--mothers: 110.7 +/- 40.1% vs 82.4 +/- 20.9%; Fb--fathers: 4.12 +/- 0.74 g/L vs 3.01 +/- 0.54 g/L; Fb--mothers: 3.64 +/- 0.84 gL vs 2.98 +/- 0.35 g/L; PC--fathers: 116.0 +/- 12.3% vs 105.6 +/- 13.7%; PC--mothers: 114.4 +/- 15.8% vs 105.0 +/- 12.2%). The children of the ICS parents had significantly higher PC and body mass index (BMI) values than the controls (PC: 102.6 +/- 13.7% vs 92.7 +/- 10.7%; BMI: 20.6 +/- 3.8 vs 17.8 +/- 3.5 Kg/m2), as well as an atherogenic lipid profile, higher blood pressure (BP) and a tendency toward higher vWF levels. Correlations between the ICS parents and their children were found for vWF, factor VIIc, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and BP, which were closer in the case of fathers. CONCLUSION: Regardless of gender, the parents with a history of ICS had a procoagulant state, with high levels of vWF, Fb and PC. In terms of inheritance, the most adverse risk factor profile was found in the children of ICS fathers.

[Fibrinogen (Fb) concentrations in patients with ischaemic heart disease undergoing coronary angiography].

Increasing evidence suggests the role of hemostatic risk factors in the development of ischemic heart disease (IHD). A raised plasma fibrinogen has been related to increased risk of IHD. The aim of the study was to determine the relationship between plasma fibrinogen and the coronary vessels state based on the coronary angiogram. 119 patients undergoing coronary angiography were classified into 5 groups according the severity of IHD: Group 0 without significant atherosclerotic lesions (control group), Group 1 with single vessel disease, Groups 2, 3 with multivessel disease (two and three affected arteries, respectively) and Group 4 with positive history of myocardial infarction. A statistically nonsignificant rise in fibrinogen levels in Groups 1, 2, 3 (3.9 +/- 0.8 g/l, 4.0 +/- 0.9 g/l, 4.1 +/- 0.9 g/l, respectively) as compared to control Group 0 (3.7 +/- 0.7 g/l) was found. In Group 4 plasma fibrinogen was significantly lower (2.8 +/- 0.6 g/l) comparing to Group 0 (p < 0.05). In addition plasma fibrinogen was positively correlated with blood pressure. These results supports the role of raised plasma fibrinogen in the pathogenesis and development of IHD.

Lp(a), homocysteine and a family history of early ischemic cerebral stroke.

BACKGROUND AND AIM: High plasma lipoprotein(a) [Lp(a)] and homocysteine (HCY) levels are now considered to be independent risk factors for cerebro- and cardiovascular atherosclerotic occlusive disease, but little is known about the influence of Lp(a) and HCY on the early events of ischemic disease or their significance in subjects with a positive family history of ischemia. The aim of this study was to evaluate the relationship between HCY levels and the severity of ischemic cerebral stroke, and investigate whether there was a correlation between Lp(a) and HCY levels in the stroke patients and their children. METHODS: The study involved 35 patients with early ischemic cerebral stroke aged 46.1 +/- 6.6 years and their 50 children aged 17.2 +/- 5.5 years. The patients were grouped on the basis of the form of the stroke (transient, progressive or complete stroke), and their levels of Lp(a), HCY, uric acid (UA), fibrinogen (Fb) and factor VII (FVII) activity were measured. RESULTS: HCY and Lp(a) concentrations increased with the severity of the ischemia, being highest in the patients with complete stroke (15.1 +/- 2.9 mumol/L and 32.9 +/- 37.6 mg/dL respectively). A similar trend was found in the offspring, with the highest HCY and Lp(a) values in the children of complete stroke patients (12.6 +/- 4.4 mumol/L and 23.0 +/- 24.6 mg/dL). The control values were respectively 8.7 +/- 1.6 mumol/L and 5.35 +/- 7.05 mg/dL. The following correlations between the parents and children were noted: Lp(a) (r = 0.87 p < 0.0001), UA (r = 0.71 p < 0.001), HCY (r = 0.45 p < 0.05), FVII (r = 0.45 p < 0.05), and Fb (r = 0.42 p = 0.06). Correlations between Lp(a) and HCY (r = 0.47 p < 0.05) and Fb and FVII (r = 0.60 p < 0.01) were found in the children. Multiple regression analysis revealed that only Lp(a) and Fb significantly influenced HCY levels in the offspring with a positive family history. CONCLUSIONS: HCY levels correlate with the severity of ischemic cerebral stroke and, in families with a history of ischemic cerebral stroke, the levels of the risk factors in children are determined by the levels in their parents.

p53 Protein accumulation as a prognostic marker of preoperative radiotherapy and/or chemotherapy in advanced squamous cell esophageal carcinoma--preliminary report.

The correlation between immunohistochemical detection (IH) of p53 protein and tumor response to preoperative chemotherapy and/or radiotherapy in advanced esophageal squamous cell carcinoma was evaluated. Fifty-six patients with advanced esophageal squamous cell carcinoma were included in the study. All patients were staged and diagnosed microscopically before treatment. Patients were divided into three groups: 17 patients treated with chemotherapy and radiotherapy preoperatively (group I) (cisplatin and 5-fluorouracil, cobalt-60 therapy; total dose 3000 Gy); 19 patients treated with chemotherapy only (group II); and 20 patients who did not receive preoperative therapy (group III). The response of the tumor tissue to preoperative treatment was evaluated macroscopically and microscopically in operated specimens according to the classification: CR, complete response; PR1, major partial response with regression of at least 50% of initial tumor mass; PR2, minor partial response with regression of less than 50% of initial tumor mass. In all 56 patients immunohistochemistry was used to detect anti-p53 antibody (Dako, DO-7) in normal mucosa and cancer tissue. The response of the tumor was similar in both group I and group II. p53 protein was not expressed in the normal esophageal mucosa. A high level of p53 in operated specimens was associated with unfavorable tumor response to preoperative treatment. Therefore, immunohistochemical detection of p53 protein can be considered to predict the outcome of preoperative therapy.

Etofibrate decreases factor VII and fibrinogen levels in patients with polymetabolic syndrome.

Etofibrate is a hypolipemic drug belonging to the fibrate class. By improving the lipid profile, these drugs often exert a favorable influence on hemostatic risk factors of ischemic heart disease. We present a pilot study on the influence of etofibrate on lipids and lipoproteins in serum, as well as on factor VII and fibrinogen. The study group was comprised of 18 males, aged 52.5 +/- 7.3 years, with hypertriglyceridemia or mixed hyperlipoproteinemia and other risk factors of atherosclerosis, particularly insulin-dependent diabetes and arterial hypertension. The group was further divided into two subgroups depending on the coexistence of arterial hypertension. All patients received etofibrate 500 mg daily for 3 months. In comparison with initial values, a decrease in the following was noted for the whole study group: triglyceride level (226.0 +/- 27.1 vs. 288.0 +/- 51.9 mg/dl; p < 0.05), percent LDL-cholesterol (72.4 +/- 1.8 vs. 75.8 +/- 1.7; p < 0.05), apolipoprotein B (111.2 +/- 4.6 vs. 115.3 +/- 5.4 mg/dl; p < 0.05), atherogenic indices: LDL/HDL (5.06 +/- 0.58 vs. 5.95 +/- 0.50; p < 0.02) and apolipoprotein B and A (apoB/apoA) (0.92 +/- 0.04 vs. 1.02 +/- 0.06; p < 0.05). There was an increase in percent HDL-cholesterol (14.7 +/- 1.1 vs. 12.8 +/- 0.7; p < 0.05) and apoA (121.0 +/- 4.8 vs. 111.2 +/- 2.4 mg/dl; p < 0.05). A marked decrease in the level of factor VII (FVIIc) (114 +/- 5.9 vs. 136 +/- 5.3%; p < 0.001) and fibrinogen (2.95 +/- 0.17 vs. 3.58 +/- 0.17 g/l; p < 0.01) was found. Fibrinogen levels fell notably (3.09 +/- 0.30 vs. 3.87 +/- 0.34 g/l; p < 0.05) in the subgroup with arterial hypertension, and F1 + 2 markers tended to decline (2.32 +/- 0.53 vs. 2.74 +/- 0.37 nmol/l; NS). Patients with normals arterial pressure maintained their fibrinogen levels (3.23 +/- 0.24 vs. 3.36 +/- 0.26 g/l; NS). A positive correlation between FVIIc and F1 + 2 was observed during treatment. All results were expressed as arithmetic means +/- SE. The present study has demonstrated that etofibrate has hypolipemic, antithrombotic and antiatherosclerotic properties in patients with polymetabolic syndrome.

The aim of this study was to estimate the incidence of occurrence of anticardiolipin autoantibodies in patients with thromboangitis obliterans (TAO). Patients with Buerger's disease had statisticaverified significant higher frequency of anticardiolipin IgM antibodies than control group. This antibody may play a role in pathogenesis of TAO, although this results should be verified because of the small number of patients and diagnostic criteria.

Increased levels of factor VII, fibrinogen and activity of plasminogen activator inhibitor during postprandial triglyceridemia in patients with ischemic heart disease confirmed by angiography.

BACKGROUND AND AIM: Impaired elimination of triglycerides (TG) after postprandial lipemia is often observed in patients with ischemic heart disease (IHD). Longer retention of TG-rich lipoproteins in the circulation may in turn be the cause of hemostatic disturbances in the form of hypercoagulation. The aim of this study was to evaluate the influence of postprandial lipemia on the hemostatic system in normolipemic patients with angiographically documented atherosclerotic changes of coronary arteries. METHODS AND RESULTS: 20 males under 60 years of age with IHD and 10 healthy males matched for age were studied. Hemostatic and lipid parameters were determined in blood collected before (fasting) and after (2, 4, 6 and 8 hours) an oral fat load (200 ml of 30% cream). A statistically significant increase in factor VII (FVIIc-%) was found during postprandial lipemia in comparison with fasting. Although in patients with IHD the area under the curve for FVIIc was not significantly different than in the control group, it was observed that FVIIc in the IHD group exceeded the fasting level earlier (4, 6 and 8 h) than in controls (8 h). Levels of FVIIc reached for the IHD group: fasting value = 96.3 +/- 16.3; postprandial 4 h = 103.2 +/- 21.3, 6 h = 105.2 +/- 21.8, 8 h = 106.0 +/- 21.4; for the controls: fasting value = 96.8 +/- 17.2; postprandial 8 h = 107.7 +/- 22.0. In the IHD group, unlike in controls, postprandial lipemia was accompanied by a statistically significant rise in fibrinogen levels (Fb-g/l) as compared with fasting (fasting value = 3.69 +/- 0.59; postprandial 2 h = 3.89 +/- 0.65, 4 h = 3.93 +/- 0.63). Mean values for PAI-1 were lower in the IHD than in the control group, but PAI-1 activity during postprandial lipemia rose earlier in the IHD group (4 and 6 h) than in the controls (6 h). PAI-1 levels were in the IHD: fasting values = 1.4 +/- 1.2; postprandial 4 h = 2.3 +/- 1.6, 6 h = 2.5 +/- 1.7; in the control: fasting value 2.9 +/- 1.7; postprandial 6 h = 3.9 +/- 2.0. The level of fragment 1 + 2 (F1 + 2) during postprandial lipemia decreased in both groups. CONCLUSIONS: The lipemic stimulus in fasting normolipemics induces a hypercoagulant effect with greater changes in patients with ischemic heart disease than in healthy subjects. Longer periods of postprandial lipemia might constitute an additional factor promoting thrombus formation in patients with dysfunction of the vascular endothelium.

[Risk factors for atherosclerosis in offspring of parents with primary hypertriglyceridemia].

High triglycerides and low fibrinolysis activity are considered as a significant predictors for atherosclerosis. The aim of our study was: 1-to compare these risk factors levels in children with positive family history of hypertriglyceridemia (HTG) with children from healthy families and 2-to assess the association between triglyceride and fibrinolysis activity in offspring (y) and parental risk factors (xl ... xn) for atherosclerosis. The study population consisted of: I Group 15 children 7-12 years old and their parents from HTG families and II Group 26 control children 5-12 years old from healthy families. Triglyceride (TG), total cholesterol, cholesterol esters, LDL-Ch, HDL-Ch, HDL2Ch, apolipoprotein AI and BII, fibrinogen plasma level were determined. Plasminogen activator inhibitor (PAI-1) and fibrinolysis activity and (ELT) were determined. We found significant differences in clinical examinations (higher blood pressure and ECG disturbances more frequently), HDL-Ch and HDL2-Ch plasma level was lower in children with positive family history than in control children. Multiple regression analysis of parental variables demonstrated, that children's TG and ELT are strongly determined by parental lipids and haemostasis parameters in children with positive family history of HTG.

[Evaluation of platelet function and tissue plasminogen activator activity in ischemic heart disease depending on concurrence with hyperlipoproteinemia and aspirin therapy].

Platelet activation, impairment of fibrinolysis and dyslipidemia are important factors in the pathogenesis and progression of ischemic heart disease. Aspirin therapy will reduce platelet activation both by its negative effect on platelet aggregation (SPA) and by inhibition of granule release which liberates such mediators as platelet factor 4 (PF4) and plasminogen activator inhibitor 1 (PAI-1). The present study was performed in 57 patients with ischemic heart disease (IHD), divided into groups depending on coexistent hyperlipoproteinemia (HLP) and aspirin treatment. The control group included 21 healthy individuals, matched for age and sex. Parameters of hemostasis (SPA, PF4, PAI-1) and concentration of lipid fractions (TC, TG, LDL, HDL) were measured in plasma. Increased PF4 levels were found in all groups with IHD, irrespective of hyperlipoproteinemia or aspirin treatment. Enhanced SPA and higher PAI-1 were limited to group IHD-HLP without aspirin. Highest PAI-1 activities were observed after stimulation of platelets in vitro. In conclusion, patients with IHD and hyperlipoproteinemia presented most pronounced platelet activation and impairment of fibrinolysis. Aspirin had a beneficial effect on these changes. Lower activities of PAI-1, in patients treated with aspirin, can be ascribed to its reduced release from platelets. Aspirin did not satisfactorily reduce the level of PF4, although it strongly inhibited SPA.

[Evaluation of lipoprotein (a) and fibrinogen levels in men after premature myocardial infarction and in their sons].

Lipoprotein (a) and fibrinogen admittedly are independent risk factors of coronary heart disease. Since Lp (a) has been shown to inhibit plasminogen binding to endothelial cells and to fibrin monomers, this led to the speculation that high Lp (a) levels in plasma could interfere with fibrinolysis. Therefore the aim of our work was to estimate the lipoprotein (a) and fibrinogen levels and to find correlation between lipoprotein (a) and fibrinogen levels at the men after a myocardial infarction and also at their sons. We examined 33 men of age 31-57 after a myocardial infarction and their 18 sons 4-14 years old. The control group consisted of 40 men of age 18-57 and their 19 sons 5-14 years old. The Lp (a) was determined with electroimmunodiffusion method and fibrinogen by Clauss method. The fibrinogen level in the examined group was found to be statistically significantly higher (338 mg/dl) than in the control group (313 mg/dl). There was no correlation between Lp(a) and fibrinogen concentration. In the group of sons of patients mean fibrinogen and Lp (a) levels were similar to those of the control group. However there was a negative correlation between the fibrinogen and the triglycerides concentration in sons of patients but not in the control group. The results seem to confirm the significance of fibrinogen as a risk factor for the development of the coronary heart disease.

[Effect of dietetic recommendations on the level of some lipid and hemostatic parameters in offspring of parents with risk factors for coronary heart disease].

Atherosclerosis, the precursor of coronary heart disease may originate in childhood. The atherogenic potential of food is related to its cholesterol and saturated-fat content. The study population consisted of children from CHD-parents under the age 12 years with plasma total cholesterol > 170 mg/dl, LDL-Ch > 90 mg/dl and ApoB > 70 mg/dl. All the patients were advised a 6 month diet following National Program of Cholesterol Prevention recommendation. Plasma, TCh, LDL-Ch, ApoB, TG, Ch-esters saturated/unsaturated ratio and platelet factor 4 concentration decreased, LCAT activity and Ch-esters unsaturated increased during study period. We observed interesting correlation between: PF4 and ApoB, PF4 and LDL-Ch and PF4 and HDL-ECh 18:3. Our data show, that proper diet can modify risk factors of CHD in children with family history of CHD.
