Opis:
Oligochitosans obtained through degradation of macromolecules of chitosan with a high degree of deacetylation turned out to be biologically active, contributing to an increase of nitric oxide levels in Ehrlich ascites tumor (EAT) cells through inducing expression of the isoform of inducible nitric oxide synthase (iNOS) gene. An increase of NO levels in EAT cells in the presence of the investigated oligochitosans might contribute to nitrosylation of L-cysteine – an allosteric effector of the M2 isoenzyme of pyruvate kinase (PK), which switches the PK kinase activity, responsible for ATP synthesis, to the histone kinase activity that may participate in histone H1 phosphorylation. Lack of the histone activity of the PK M2 isoenzyme may contribute to decreased histone H1 phosphorylation and thus inhibit EAT cells proliferation.

We investigated the cytotoxic effect of nitric oxide (NO) on primary culture of human hematological malignant cells. Sodium nitroprusside (SNP), an NO donor, had cytotoxic effects on the cells of some patients with malignant lymphoma (ML), acute myelocytic leukemia (AML) or chronic myelomonocytic leukemia (CMMoL), but not with multiple myeloma. Cultured cells from the ML patient remained sensitive to SNP after the cells became resistant to anti-cancer drugs. In contrast, the cells from the patients with AML and CMMoL became resistant to SNP while anti-cancer drugs remained effective. In samples of the cells of the patients with ML and AML, the number of CD3 positive lymphoma cell was decreased by SNP and the number of CD33 negative cells and normal B lymphocytes (CD19 positive cells) were increased. In the cells of the patient with ML, apoptosis was induced by SNP. SNP had no effect on lymphocytes of healthy volunteers. These results suggest that SNP had an anti-tumor effect on human hematological malignant cells.

Opis:
COVID-19-associated ARDS (cARDS) results from multiple pathogenetic mechanisms involving both parenchyma and circulation of the lungs. Despite authors described two pneumonia phenotypes according to lung elastance values, reported as Low and High phenotype, the evidence suggests that patients with cARDS have similar respiratory mechanics to patients with ARDS from other causes. Consequently, the proper management of patients with cARDS is the same as ARDS,consisting of protective mechanical ventilation strategy and prone position ventilation.However, the hypothesis that impaired alveolar perfusion could have a role in cARDS is interesting. Nitric oxide (NO) is a biatomic gaseous moleculeables to induce smooth muscle relaxation and vasodilation. So, inhaled nitric oxide (iNO) acts as a selective vasodilator because it only dilates vessels in areas participating in gas exchange, preserving hypoxic pulmonary vasoconstriction reflex and reducing ventilation/perfusion mismatch. With this narrative review we summarised the role of iNO for cARDS treatment to improve gas exchange. Furthermore, we briefly described its activity as an antiviral agent. In conclusion, although iNO administration can represent a valid theoretical therapeutic choice for the treatment of severe unresponsive hypoxemia in COVID-19 patients, data presented in the literature are scares and inconclusive, and several clinical trials are still ongoing. Further studies are needed to elucidate the pathogenetic mechanism of respiratory failure related to SARS-CoV-2 infection and inhaled NO role in patients with severe disease.

Opis:
Introduction. The fraction of exhaled nitric oxide (FeNO) is used as a non-invasive biomarker that reflects inflammation in the airways. It is so versatile that it used to control asthma severity as well as to monitor response to treatment. However, the exact cut-off point of the nitric oxide level which allows one to make a precise diagnosis of asthma is unclear. Aim. To examine the possibility of using advanced statistical methods such as receiver operating characteristic for the analysis of FeNO concentrations for improving the diagnosis of asthma. Materials and methods. Receiver operating characteristic (ROC) was used for analyzing results to determine levels of nitric oxide which may be a prognostic indicator of asthma. The studied group consisted of 111 children including 69 asthmatic patients, and 42 age- and sex-matched healthy subjects. Measurement of exhaled nitric oxide was conducted in all subjects included in this study. Results. FeNO level was higher in asthmatic patients. The analysis of results showed that the cut-off point for the FeNO concentration is 11.5 ppb. Sensitivity and specificity with the FeNO level allowed us to determine a value of the diagnostic variable of FeNO concentration of 14.0 ppb. A comparison of FeNO level and sex of the subjects showed there is no correlation between these parameters of patients. Conclusions. Currently, the FeNO measurement provides complementary d

Opis:
Investigation of the mechanisms of phenotypic realization of allelic polymorphism of the eNOS gene has shown that the level of eNOS mRNA and activity of this enzyme in platelets depends from genotype. We identified a T-786→C polymorphism in the promoter region, a variable number of tandem repeats (4a/4b) in intron 4 and the G894→T polymorphism in exon 7 of the eNOS gene in isolated human platelets. We measured eNOS mRNA in isolated platelets by reverse transcription-PCR and eNOS enzyme activity by fluorimetric detection system FCANOS-1 using diaminofluorescein diacetate (DAF-2A). It was shown that the level of eNOS mRNA is the lowest for the -786C/C promoter genotype. In exon 7 homozygotes (894T/T) the level of RNA is lower than in normal homozygotes (894G/G), but higher than in heterozygotes (894G/T). The eNOS activity in platelets is lower in carriers of the 786C/C promoter genotype than in normal homozygotes (2.1 × P=0.03), and lower comparing to heterozygotes (2.9 × P>0.05). The eNOS activity accompanying the 894T/T variant of exon 7 is also lower than in normal homozygotes (P>0.05). Regarding the polymorphism in intron 4 - the enzyme's activity is lower in carriers of the 4a/4a genotype comparing to normal homozygotes (1.7 × P>0.05) and lower than in heterozygotes (1.9 × P>0.05). These results allow one to conclude that the T-786→C polymorphism of the eNOS gene promoter most significantly affects the gene expression and eNOS activity.

Introduction. Kidney damage during pregnancy constitutes a diagnostic and therapeutic challenge. However, it is not entirely known whether a kidney condition recognised before the pregnancy releases an organism’s response to pregnancy, or whether pregnancy itself worsens kidney function. Objective. The aim of the study was immunohistochemical evaluation of cells of kidneys of pregnant rats under the influence of nitric oxide (NO), with measurement of the immunoexpression of cellular stress markers (p-53, HSP 70). The dose of administered L-arginine (NO substrate) was approximated to that applied in obstetrics in gestosis prevention and treatment in pregnant women. Materials and method. 60 female rats used in experiment were divided into 6 groups: 3 experimental and 3 control. The females from experimental groups were administered L-arginine (40g/kg, per os) every other day starting from the seventh day or pregnancy. The animals were decapitated on the 10th, 20th day of pregnancy, and 10 days after the delivery. Kidneys taken from decapitated rats were evaluated using the immunohistochemical three step method. HSP 70 and p-53 proteins were detected. Conclusions. L-arginine increased the expression of p-53 protein – on the 10th day of pregnancy, which increased at the end of pregnancy; however, 10 days after delivery the level dropped below that observable during physiological pregnancy. Hormonal changes in physiological pregnancy cause an increase in expression of the p-53 (cell stress marker) in the epithelial cells of renal tubules, mainly at the end of pregnancy (20th day). 10 days after the delivery, this expression decreases. The expression of HSP-70 protein increases already on the 10th day of pregnancy and maintains a similar level throughout the pregnancy, but is reduced after the puerperium.

Opis:
The proper functioning of the perinatal sucking reflex in calves is essential for the prevention of milk leakage into the rumen. The complex process behind its regulation is mediated at the gut level via multiple excitatory and inhibitory neurotransmitters, of which acetylcholine and nitric oxide are of fundamental importance. The aim of our study was to depict age-related alterations in the cholinergic and nitrergic innervation of the esophageal groove (EG) using immunohistochemistry and Real-Time PCR methods. We found out that the highest number of cholinergic nerve cells was present in the second trimester fetuses. From this developmental stage onward, their amount was gradually decreasing and reached the lowest value in 4-year-old cows. The same developmental pattern was observed for nitrergic nerve structures with the highest percentage of nitrergic neurons in the third trimester fetuses. Our observations prove that both neuronal populations are crucial for a proper closure of EG in calves. Therefore, their contribution to a general neuronal activity in the ENS diminishes with age as the high motility of a gastric groove is not necessarily required in older cattle.

Introduction and aim. The aim of this work is to study the parameters of the nitric oxide (NO) system in the blood of guinea pigs under the conditions of the experimental periodontitis (EP) and immobilization stress (IS) formation and to evaluate the effectiveness of thiocetam use. Material and methods. Experimental studies were performed on 50 guinea pigs (males, body weight 0.18–0.21 kg) which were divided into five groups (10 in each): the first group were intact animals as control; the second experimental group were animals with experimental periodontitis under conditions of immobilization stress (3rd day), the third group included guinea pigs with EP and IS on the 5th day of the combined model process, group IV – animals with EP and IS 15th day (without administration of thiocetam) and group V – animals on the 15th day of experiment with EP and IS after use of thiocetam. Results. As a result of this research, changes in the activity of the NO system in the blood were observed, namely an increase in the level of stable metabolites and an increase in the activity of total NO-synthase, which is accompanied by a compensatory inhibition of the L-arginine activity, and these indicators were most pronounced in the late stages of EP and IS formation. Conclusion. The use of thiocetam showed a corrective effect on the changed variables of NO metabolism in the peripheral blood of guinea pigs under the conditions of the EP and IS development.

Opis:
This study was undertaken to determine whether nitric oxide (NO) can affect platelet responses through the inhibition of energy production. It was found that NO donors: S-nitroso-N-acetylpenicyllamine, SNAP, (5-50 μM) and sodium nitroprusside, SNP, (5-100 μM) inhibited collagen- and ADP-induced aggregation of porcine platelets. The corresponding IC50 values for SNAP and SNP varied from 5 to 30 μM and from 9 to 75 μM, respectively. Collagen- and thrombin-induced platelet secretion was inhibited by SNAP (IC50 = 50 μM) and by SNP (IC50 = 100 μM). SNAP (20-100 μM), SNP (10-200 μM) and collagen (20 μg/ml) stimulated glycolysis in intact platelets. The degree of glycolysis stimulation exerted by NO donors was similar to that produced by respiratory chain inhibitors (cyanide and antimycin A) or uncouplers (2,4-dinitrophenol). Neither the NO donors nor the respiratory chain blockers affected glycolysis in platelet homogenate. SNAP (20-100 μM) and SNP (50-200 μM) inhibited oxygen consumption by platelets. The effect of SNP and SNAP on glycolysis and respiration was not reduced by 1H-[1,2,4]oxadiazolo-[4,3-a]quinoxalin-1-one, a selective inhibitor of NO-stimulated guanylate cyclase. SNAP (5-100 μM) and SNP (10-300 μM) inhibited the activity of platelet cytochrome oxidase and had no effect on NADH:ubiquinone oxidoreductase and succinate dehydrogenase. Blocking of the mitochondrial energy production by antimycin A slightly affected collagen-evoked aggregation and strongly inhibited platelet secretion. The results indicate that: 1) in porcine platelets NO is able to diminish mitochondrial energy production through the inhibition of cytochrome oxidase, 2) the inhibitory effect of NO on platelet secretion (but not aggregation) can be attributed to the reduction of mitochondrial energy production.

It has been reported that concentrations of neopterin in the urine are changed according to the host immunological conditions. In the present study, we measured urinary concentration of neopterin in patients with malignant hematological disorders and investigated the relationship between urinary neopterin levels and laboratory indices for cellular immunity. Urine neopterin levels were correlated with serum sIL-2R levels in the patients with malignant lymphoma, and inversely correlated with lymphocyte reactivity with ConA in the patients with acute myelocytic leukemia. However, no significant correlation was observed between urine neopterin levels and lymphocyte reactivity with phytohemagglutinin and pokeweed mitogen, CD4/8 ratio, CD56+16+ subset or serum IFN-β levels. In the patients with malignant lymphoma, parallel changes in serum sIL-2R and urine neopterin were observed. The presented results suggest that urine neopterin levels are related to the activation of T cells in malignant lymphoma.

The results of experimental investigations on the removal of NOx from gases applying ozone as the oxidizing agent and the absorption of higher nitrogen oxides in the sodium hydroxide solutions are presented. The experiment was conducted using a pilot plant installation with the air flow rate 200 m3/h, being a prototype of a boiler flue gas duct and a FGD scrubber. It was shown that in the range of [NOref] = 50 ÷ 250 ppm the mechanism of NO ozonation depends on the molar ratio X = O3/NOref: for X ≤ 1.0 oxidation of NO to NO2 predominates and NO2 is poorly absorbed, for X >> 1.0 NO2 undergoes further oxidation to N2O5, which is efficiently absorbed in the scrubber. The stoichiometric molar ratio of complete conversion of NO into N2O5 is X = 1.5, in these studies to reach the effectiveness η ≥ 90% the molar ratio X was much higher (2.75).
Przedstawiono wyniki badań doświadczalnych dotyczące usuwania NOx z gazów z zastosowaniem ozonu jako utleniacza i absorpcji wyższych tlenków azotu w roztworach wodorotlenku sodu. Badania prowadzono na strumieniu powietrza 200 m3/h w instalacji pilotowej będącej prototypem instalacji kotłowej odprowadzenia spalin i skrubera IOS. Wykazano, że w zakresie [NOref] =50÷250 ppm mechanizm ozonizacji NO zależy od stosunku molowego X = O3/NOref: dla X ≤ 1.0 przeważa utlenianie NO do NO2 a NO2 jest słabo absorbowany, dla X >> 1,0 NO2 ulega dalszemu utlenianiu do N2O5, który jest efektywnie absorbowany w skruberze. Stosunek molowy przy całkowitej konwersji NO do N2O5 wynosi X = 1.5, w przeprowadzonych badaniach, aby osiągnąć efektywność η ≥ 90% stosunek X był dużo większy (2,75).
