The current study was conducted in order to investigate the cellular-physiological responses of some enzymatic endogenous antioxidants of parasitic infection that were performed as a cellular metabolically defenses through estimation of oxidative stress biomarkers as indicators in patients with cutaneous leishmania and evaluation of these responses of endogenous antioxidants. The study included an individual of both genders: 60 patients with cutaneous leishmaniasis (CL) and 30 healthy individuals. Study volunteers were distributed into three age groups (1-20), (21- 40), and (41-60) years. The demographic data were collected for both the patient and healthy groups, including age and ABO-Rh blood groups. Also, the laboratory measurements were performed for all venous blood samples taken from patients and healthy subjects including measure the concentrations of oxidative stress biomarkers total oxidants status (TOS) and malondialdehyde (MDA), and the concentrations of enzymatic antioxidants superoxide dismutase 1 (SOD1) and glutathione peroxidase 1 (GPX1). The demographical study revealed that the incidence of CL disease more occurs in males than females within early and mid-ages. On the other hand, a higher percentage of CL incidences were an early age (1–20 years) and mid-age (21–40 years). In addition, the predominant blood type among CL patients was A+ followed by O+ > B+ >AB+ and B- > A- > O- >AB- . The serum biochemical assays of cutaneous leishmaniasis patients indicated for a significant increase in serum concentrations of (TOS) and (MDA), and a significant decrease in concentrations of SOD1 and GPX1 in comparison to the healthy group for all sample age ranges. It is concluded that the pathogenesis of cutaneous leishmaniasis caused cellular oxidative stress represented by the high production of free radicals which functionally depleted the cellular metabolically levels of serum endogenous enzymatic antioxidants.

Urinary concentrations of 16 different exposure biomarkers to metals were determined at the beginning and at the end of a working shift on a group of workers in the metal carpentry industry. Five different oxidative stress biomarkers were also measured, such as the oxidation products of RNA and DNA metabolized and excreted in the urine. The results of workers exposed to metals were compared to those of a control group. The metal concentrations found in these workers were well below the occupational exposure limit values and exceeded the mean concentrations of the same metals in the urine of the control group by a factor of four at maximum. Barium (Ba), mercury (Hg), lead (Pb) and strontium (Sr) were correlated with the RNA oxidative stress biomarker, 8-oxo-7, 8-dihydroguanosine (8-oxoGuo), which was found able to discriminate exposed workers from controls with a high level of specificity and sensitivity. The power of this early diagnostic technique was assessed by means of the ROC curve. Ba, rubidium (Rb), Sr, tellurium (Te), and vanadium (V) were correlated with the level of the protein oxidation biomarker 3-Nitrotyrosine (3-NO2Tyr), and Ba, beryllium (Be), copper (Cu), and Rb with 5-methylcytidine (5-MeCyt), an epigenetic marker of RNA damage. These effect biomarkers can help in identifying those workers that can be defined as “occupationally exposed” even at low exposure levels, and they can provide information about the impact that such doses have on their health.

AbstractThe aim of our study was to elucidate the effects of both development stages (parr, smolt, adult, spawner), and kelt as a survival form and sex (male, female) on the functional stability of the lysosomal complex, biomarkers of oxidative stress, and element contents in the muscle tissue of the sea trout (Salmo trutta m. trutta L.) sampled in the Pomerania region (northern Poland). We have evaluated the maximal activities of lysosomal enzymes (alanyl aminopeptidase, leucyl aminopeptidase, β-N-acetylglucosaminidase, and acid phosphatase), lipid peroxidation level, and protein carbonyl derivatives as indices of muscle tissue degradation. The relationship between lysosomal activity and oxidative stress biomarkers estimated by the lipid peroxidation level and protein carbonyl derivatives was also assessed, as well as the relationships between element levels and oxidative stress biomarkers. Trends of the main effects (i.e., the development stages and sex alone, the interaction of the sex and development stage simultaneously) on oxidative stress biomarkers, lysosomal functioning, and element contents in the muscle tissue were evaluated. The study has shown sex-related relationships between the pro- and antioxidant balance and the tissue type in the adult stage as well as modifications in the lysosomal functioning induced by long-term environmental stress associated with changing the habitats from freshwater to seawater and intense migrations. The highest level of toxic products generated in oxidative reactions and oxidative modification of proteins was noted in both the spawner stage and the kelt form. The holistic model of analysis of all parameters of antioxidant defense in all development stages and sex demonstrated the following dependencies for the level of lipid peroxidation, oxidative modification of proteins, lysosomal activities, and element contents: TBARS > OMP KD > OMP AD > TAC, AcP > NAG > LAP > AAP and Cu > Fe > Ca > Mn > Zn > Mg, respectively.
