Abstract
Animal tumors serve as reasonable models for human cancers. Both human and animal tumors often reveal triplet EPR signals of nitrosylhemoglobin (HbNO) as an effect of nitric oxide formation in tumor tissue, where NO is complexed by Hb. In search of factors determining the appearance of nitrosylhemoglobin (HbNO) in solid tumors, we compared the intensities of electron paramagnetic resonance (EPR) signals of various iron-nitrosyl complexes detectable in tumor tissues, in the presence and absence of excess exogenous iron(II) and diethyldithiocarbamate (DETC). Three types of murine tumors, namely, L5178Y lymphoma, amelanotic Cloudman S91 melanoma, and Ehrlich carcinoma (EC) growing in DBA/2 or Swiss mice, were used. The results were analyzed in the context of vascularization determined histochemically using antibodies to CD31. Strong HbNO EPR signals were found in melanoma, i.e., in the tumor with a vast amount of a hemorrhagic necrosis core. Strong Fe(DETC)2NO signals could be induced in poorly vascularized EC. In L5178Y, there was a correlation between both types of signals, and in addition, Fe(RS)2(NO)2 signals of non-heme iron-nitrosyl complexes could be detected. We postulate that HbNO EPR signals appear during active destruction of well-vascularized tumor tissue due to hemorrhagic necrosis. The presence of iron-nitrosyl complexes in tumor tissue is biologically meaningful and defines the evolution of complicated tumor-host interactions.

Abstract
Electron paramagnetic resonance (EPR) spectroscopy is the ideal methodology to identify radicals (detection and characterization of molecular structure) and to study their kinetics, in both simple and complex biological systems. The very low concentration and short life-time of NO and of many other radicals do not favor its direct detection and spin-traps are needed to produce a new and persistent radical that can be subsequently detected by EPR spectroscopy.In this chapter, we present the basic concepts of EPR spectroscopy and of some spin-trapping methodologies to study NO. The "strengths and weaknesses" of iron-dithiocarbamates utilization, the NO traps of choice for the authors, are thoroughly discussed and a detailed description of the method to quantify the NO formation by molybdoenzymes is provided.

Abstract
The reactions of nitric oxide with hemoglobin play an important role in explaining the vascular biology of this free radical. It is perhaps surprising that the level of nitrosylhemoglobin (HbNO) in which NO is bound to the ferrous hemoglobin heme in whole human blood under basal and stimulated conditions is a matter of some controversy, with measurements ranging from <1 nm to close to 10 mum. In order to examine HbNO levels in human blood by using EPR spectroscopy, we have developed a regression-based spectral analysis technique that has a detection level of about 200 nm HbNO. We have utilized this methodology to detect the level of HbNO under basal conditions and during NO inhalation. The major findings of this study are as follows. (i) HbNO can be accurately detected and quantified in whole blood with a detection limit of approximately 200 nm. (ii) By using regression analysis, levels of HbNO as low as 0.5-1 mum can be deconvoluted into component species. (iii) HbNO is present at less than 200 nm at basal conditions in both arterial and venous blood and is formed at a level of 0.5-2.5 mum upon inhalation of 80 ppm NO. (iv) The levels of HbNO detected by EPR are remarkably close (within a factor of 2) to those detected by tri-iodide-based chemiluminescence and much smaller than those detected by photolysis chemiluminescence. (v) The half-time of HbNO in vivo is approximately 40 min.

Abstract
Photolysis of denatured HbNO were carried out at temperatures below 26 K. The normalized kinetic curves were fitted using either two exponentials or a conformational substate energy distribution or a fractal model. The parameters are related to the protein structure. The two exponentials model assumes the existence of two fractions of photolysed molecules that rebind with slow and fast reaction rates. Only the slow reaction rate is sensitive to the denaturation process. The pre-exponential factor and the peak energy of the substate distribution values suggest an increase in the entropy and a decrease of the flexibility in the denatured samples, respectively. The fractal model parameters strengthened the functional relevance of the flexibility of the protein chain.

Abstract
The Q-band (35 GHz) electron paramagnetic resonance (EPR) spectra of nitrosyl hemoglobin (HbNO) and nitrosyl myoglobin (MbNO) were studied as a function of temperature between 19 K and 200 K. The spectra of both heme proteins show two classes of variations as a function of temperature. The first one has previously been associated with the existence of two paramagnetic species, one with rhombic and the other with axial symmetry. The second one manifests itself in changes in the g-factors and linewidths of each species. These changes are correlated with the conformational substates model and associate the variations of g-values with changes in the angle of the N(his)-Fe-N(NO) bond in the rhombic species and with changes in the distance between Fe and N of the proximal (F8) histidine in the axial species.

Abstract
The EPR spectra of nitrosyl hemoglobin and myoglobin in different conditions (native, denatured and lyophilized), as well as of hematin-NO were obtained in the temperature range of 80-280 K. There is a substantial and reversible decrease of the areas of the EPR spectra of all the hemoglobin samples above 150 K. The interpretation of the results implies the existence of two conformational states in thermal equilibrium, only one of which is EPR detectable. Thermodynamical parameters are determined for the hexa- and penta-coordinated cases.

Abstract
The scavenging effect of Chinonin on NO and oxygen free radicals and its protective effect on myocardium from the ischemia-reperfusion injury was studied with electron spin resonance (ESR) and chemiluminescence techniques. Chinonin can effectively inhibit the oxidative activity of ONOO-, (the IC50 = 7 x 10 (-5) mmol/L) and scavenge oxygen free radicals generated from the reaction of xanthine and xanthine oxidase (the IC50 = 2/5 x 10(-4) mmol/l). It is difficult to find another antioxidant which can scavenge so effectively both ONOO- and oxygen free radicals simultaneously. In the system of ischemia-reperfusion injury of myocardium, Chinonin can, in parallel, scavenge the NO and oxygen free radicals generated from the ischemia-reperfused myocardium, and decrease the activities of lactate dehydrogenase (LDH) and creatine kinase (CK) in the coronary artery effluent of ischemia-reperfused heart and therefore protect the heart from ischemia-reperfusion injury. The protective effect of 0.1 mmol/l Chinonin is similar to that of 1500 U/ml SOD and catalase.

Abstract
Photolysis of nitrosyl haemoglobin (HbNO) has been studied from 6.5 K to 20 K for different NO saturation conditions. The kinetic curves are fitted equally well by a biphasic exponential and a distribution of activation energies. The parameters are straightforwardly related to the quaternary structure of the protein. The biphasic model indicates that two germinate processes in the NO reassociation to Hb dominate at low temperatures independent of the protein conformation.

Abstract
In this ESR work we have studied the pentacoordinate symmetry in horse, whale and sperm-whale myoglobin (Mb) in different physical states such as solution and powder. Experiments were performed in which the following parameters were varied: the sample temperature, pH, reaction time with NO, and NO concentration. The results enabled us to explain the NO reaction mechanism in the oxy and met forms of myoglobin. The study of powder samples at different degrees of hydration allowed us to identify the diamagnetic intermediate species existent in the reaction of NO with met-Mb proposed in the literature. The results presented explain adequately the pH effect and temperature dependence observed in the ESR spectra obtained using the met-Mb sample solutions from Sigma Chemical Co., which consist of a mixture (13%) of Mb-O2.

Abstract
Our aim is to study the binding of nitric oxide to human hemoglobin with different water contents. The binding is investigated using electron paramagnetic resonance (EPR), considering the paramagnetic character of the nitric oxide hemoglobin derivative. The EPR spectra obtained are made up of two types of spectrum whose proportions vary with the decrease in hydration down to about 0.25 g H2O per g protein, and are constant below this value. The two types of spectrum are interpreted as two possible configurations of the heme pocket in different populations of nitric oxide hemoglobin.
