AB  - Asymptomatic outdoor dogs can be carriers of Babesia canis, but data describing the development of an acute phase response (APR) are not available. We hypothesised that these dogs have a moderate APR that could be detected by hematological and biochemical changes. Two groups of Babesia-exposed dogs were represented by nine B. canis PCR-positive and twenty B. canis PCR-negative, seroreactive dogs. The control group consisted of ten Babesia-naïve dogs. Serum amyloid A (SAA), paraoxonase-1 (PON-1), complete blood count, and biochemistry parameters were analysed by standard methodologies. Protein and lipoprotein fractions were separated using agarose gel electrophoresis (GE), and the dominant diameters of lipoproteins were assessed on gradient GE. Results were evaluated using non-parametric tests and the Receiver Operating Characteristic curve. SAA (median 39.0 μg/mL, range 2.2–48.8 μg/mL), total protein (median 74.7 g/L, range 57.1–98.3 g/L) and the dominant diameter of α-lipoproteins (median 13.31 nm, range 12.09–14.17 nm) in B. canis PCR-positive dogs were higher relative to dogs in the control group or dogs that were PCR-negative but seroreactive (p < 0.001 for both groups). Mild to moderate anemia (4/29), thrombocytopenia (7/29), and leukocyte counts that were close to the upper limit of the reference range were encountered in both Babesia-exposed groups. When compared to controls, Babesia-exposed dogs displayed decreased a PON-1 activity and protein GE pattern consistent with low-grade chronic inflammation (p < 0.001 for both groups). Dogs with detectable amounts of B. canis DNA in blood contain increased levels of SAA and total protein along with α-lipoproteins that display an increased diameter relative to those dogs with positive Babesia serology but undetectable levels of B. canis DNA in blood.

AB  - This study is aimed at analysing biochemical and genetic endpoints of toxic effects after administration of adrenaline. For this purpose, the study was carried out on Wistar rats and three doses of adrenaline were used: 0.75 mg/kg, 1.5 mg/kg, and 3 mg/kg body weight. To achieve these aims, we investigated the effects of adrenaline on catalase (CAT), Cu, Zn-superoxide dismutase (SOD), malondialdehyde (MDA), nitrite (NO2-), carbonyl groups (PCC), and nitrotyrosine (3-NT). Total activity of lactate dehydrogenase (LDH), its relative distribution (LDH1-LDH5) activity, level of acute phase proteins (APPs), and genotoxic effect were also evaluated. The obtained results revealed that all doses of adrenaline induced a significant rise in CAT activity, MDA level, PCC, NO2-, and 3-NT and a significant decrease in SOD activity compared to control. Adrenaline exerted an increase in total activity of LDH, LDH1, and LDH2 isoenzymes. Further study showed that adrenaline significantly decreased serum albumin level and albumin-globulin ratio, while the level of APPs (alpha(1) -acid glycoprotein and haptoglobulin) is increased. The micronucleus test revealed a genotoxic effect of adrenaline at higher concentrations (1.5 mg/kg and 3 mg/kg body weight) compared to untreated rats. It can be concluded that adrenaline exerts oxidative and nitrative stress in rats, increased damage to lipids and proteins, and damage of cardiomyocytes and cytogenetic damage. Obtained results may contribute to better understanding of the toxicity of adrenaline with aims to preventing its harmful effects.

AB  - The success of antioxidant therapy in hyperthyroidism implies that disease is mediated by oxidative stress, which is known as one of the causing agents of agemg, degenerative diseases, and cancer. The main objective of our study was to determine possible protective effects of methanolic extract of N. rtanjensis in triiodothyronine (T-3)-induced DNA breaks of human lymphocytes under in vitro conditions, based upon plant antioxidant capacity related to its phytochemical profile, mainly its polyphenolic complex. The total phenolic and flavonoid content and the antioxidant activity using in vitro 1,1-dyphenyl-2-picrylhydrazyl reagent (DPPH) was determined in methanolic extracts of plant leaves and flowers. The phenolic compound content of 62.73 +/- 1.80 mg of GaA/g, exhibited solid antioxidant activity (IC50= 112.59 +/- 0.95 g/ml). The antigenotoxic activity of 0.2, 0.5 and 1.0 mg/ml N. rtanjensis methanol extracts mixture with 100 mu M of T-3 was studied in human lymphocytes in vitro using the Comet assay. It is supposed that the antigenotoxicity of N. rtanjensis methanol extracts was caused by high presence of chlorogenic acid, rosmarinic acid and rutin, all known as efficient antioxidant bioactive compounds, which were determined by ultrahigh-pressure liquid chromatograph with MS/MS Mass Spectroscopy (UHPLC/-HESI-MS/MS).

AB  - Catechol groups can be involved in redox cycling accompanied by generation of reactive oxygen species (ROS) which may lead to oxidative damage of cellular macromolecules including DNA. The objective of this investigation was to evaluate possible genotoxic effects of a natural catecholamine adrenaline in cultured human lymphocytes using cytogenetic (sister chromatid exchange and micronuclei) and the single cell gel electrophoresis (Comet) assay. In cytogenetic tests, six experimental concentrations of adrenaline were used in a range from 0.01-500 mu M. There were no indications of genotoxic effects of adrenaline in sister chromatid exchange and micronucleus tests. However, at four highest concentrations of adrenaline (5 mu M, 50 mu M, 150 mu M and 300 mu M) we observed a decreased mitotic index and cell-cycle delay. In addition, in the Comet assay we used adrenaline in a range from 0.0005-500 mu M, at two treatment times: 15 min or 60 min. In contrast to cytogenetic analysis, there was a dose-dependent increase of DNA damage detected in the Comet assay. These effects were significantly reduced by concomitant treatment with quercetin or catalase. Therefore, the obtained results indicate that adrenaline may exhibit genotoxic effects in cultured human lymphocytes, most likely due to production of reactive oxygen species.

AB  - Ephedrine, a natural alkaloid from plants of the genus Ephedra, has a chemical structure similar to catecholamines. It is well established that catecholamines (adraneline, noradrenaline and dopamine) cause genotoxic and mutagenic effects. Therefore, the objectives of this investigation were to examine weather ephedrine can exhibit genotoxic effects on isolated human lymphocytes in the Comet assay. Dose-response of human lymphocytes was determined at the concentration range of ephedrine from 0.0005 μM to 500 μM. Three concentrations of ephedrine (1, 50 and 300 μM) which had acceptable cell viability (over 90%) were used for further experiments with inhibitors of DNA reparation (cytosine arabinoside and hydroxyurea). The obtained results showed that ephedrine did not induce DNA damage in isolated human lymphocytes. However, co-treatment of the negative control with DNA repair inhibitors caused a slight but significant increase of DNA damage, due to an endogenous DNA damage. Interestingly, cells treated with ephedrine and DNA repair inhibitors did not express increased DNA damage. On the basis of the obtained results it can be concluded that ephedrine did not exhibit genotoxic effects on isolated human lymphocytes. This result is in accordance with previous investigations showing negative genotoxicological results for ephedrine using bacterial gene mutation test-systems and in vitro cytogenetic analysis.
AB  - Efedrin, prirodni alkaloid iz biljaka roda Ephedra, ima sličnu hemijsku strukturu sa kateholaminima. Dobro je poznato da kateholamini (adrenalin, noradrenalin i dopamin) mogu da prouzrokuju genotoksične i mutagene efekte. Stoga su ciljevi ovog istraživanja bili da se ispita da li efedrin može da ispolji genotoksične efekte na izolovanim limfocitima čoveka u Komet testu. Odnos doza-efekat određ en je u rasponu koncentracija efedrina od 0.0005 μM do 500 μM. Tri koncentracije efedrina (1, 50 and 300 μM) koje su imale prihvatljiv nivo ćelijske vijabilnosti (preko 90%) upotrebljene su za dalje eksperimente sa inhibitorima reparacije DNK (citozin arabinozid i hidroksiurea). Dobijeni rezultati pokazuju da efedrin nije indukovao oštećenja DNK na izolovanim limfocitima čoveka. Međutim, istovremeni tretman sa inhibitorima reparacije DNK doveo je do malog ali statistički značajnog porasta oštećenja DNK kod negativne kontrole, usled endogenog oštećenja DNK. Interestantno je da ćelije tretirane sa efedrinom i inhibitorima reparacije DNK nisu ispoljile povećan nivo oštećenja DNK. Na osnovu dobijenih rezultata može se zaključiti da efedrin nije ispoljio genotoksične efekte na izolovanim limfocitima čoveka. Ovaj rezultat je u saglasnosti sa prethodnim istraživanjima u kojima je dokazano da efedrin ne dovodi do genotoksičnih efekata u bakterijskim testovima na genske mutacije i u in vitro citogenetičkim analizama.

Tri koncentracije efedrina (1, 50 and 300 μM) koje su imale prihvatljiv nivo ćelijske vijabilnosti (preko 90%) upotrebljene su za dalje eksperimente sa inhibitorima reparacije DNK (citozin arabinozid i hidroksiurea). Dobijeni rezultati pokazuju da efedrin nije indukovao oštećenja DNK na izolovanim limfocitima čoveka. Međutim, istovremeni tretman sa inhibitorima reparacije DNK doveo je do malog ali statistički značajnog porasta oštećenja DNK kod negativne kontrole, usled endogenog oštećenja DNK. Interestantno je da ćelije tretirane sa efedrinom i inhibitorima reparacije DNK nisu ispoljile povećan nivo oštećenja DNK. Na osnovu dobijenih rezultata može se zaključiti da efedrin nije ispoljio genotoksične efekte na izolovanim limfocitima čoveka. Ovaj rezultat je u saglasnosti sa prethodnim istraživanjima u kojima je dokazano da efedrin ne dovodi do genotoksičnih efekata u bakterijskim testovima na genske mutacije i u in vitro citogenetičkim analizama.",
