AB  - The aim of the study was to investigate if alcohol and disulfiram (DSF) individually and in combination affect bioelements' and red-ox homeostasis in testes of the exposed rats. The animals were divided into groups according to the duration of treatments (21 and/or 42 days): C-21/C-42 groups (controls); OL21 and OL22-42 groups (0.5 mL olive oil intake); A(1-21) groups (3 mL 20% ethanol intake); DSF1-21 groups (178.5 mg DSF/kg/day intake); and A(21)+DSF22-42 groups (the DSF ingestion followed previous 21 days' treatment with alcohol). The measured parameters in testes included metals: zinc (Zn), copper (Cu), iron (Fe), magnesium (Mg) and selenium (Se); as well as oxidative stress (OS) parameters: superoxide anion radical (O-2(center dot-)), glutathione reduced (GSH) and oxidized (GSSG), malondialdehyde (MDA), hydrogen peroxide (H2O2) decomposition and activities of total superoxide dismutase (tSOD), glutathione-Stransferase (GST) and glutathione reductase (GR). Metal status was changed in all experimental groups (Fe rose, Zn fell, while Cu increased in A(21)+DSF24-32 groups). Development of OS was demonstrated in A(1-21) groups, but not in DSF1-21 groups. In A(21)+DSF22-42 groups, OS was partially reduced compared to A groups (A(1-21)>MDA>C; A(1-21) lt GSH lt C). High metal-binding affinity of DSF/DDTC changes red-ox homeostasis in rat testes.

AB  - Examination of cadmium (Cd) toxicity and disulfiram (DSF) effect on liver was focused on oxidative stress (OS), bioelements status, morphological and functional changes. Male Wistar rats were intraperitoneally treated with 1mg CdCl2/kg BW/day; orally with 178.5 mg DSF/kg BW/day for 1, 3, 10 and 21 days; and co-exposed from 22nd to 42nd day. The co-exposure nearly restored previously suppressed total superoxide dismutase (SOD), catalase (CAT) and increased glutathione peroxidase (GPx) activities; increased previously reduced glutathione reductase (GR) and total glutathione-S-transferase (GST) activities; reduced previously increased superoxide anion radical (O-2(center dot-)) and malondialdehyde (MDA) levels; increased zinc (Zn) and iron (Fe), and decreased copper (Cu) (yet above control value), while magnesium (Mg) was not affected; and decreased serum alanine aminotransferases (ALT) levels. Histopathological examination showed signs of inflammation process as previously demonstrated by exposure to Cd. Overall, we ascertained partial liver redox status improvement, compared with the formerly Cd-induced impact.

AB  - The objective of our study was to examine testicular toxicity of cadmium (Cd), focusing on oxidative stress (OS), essential metals and androgenic status and morphological changes. Male Wistar rats [controls and four Cd-subgroups (n = 6) organized according to the exposure (1, 3, 10 and 21 days)] were intraperitoneally (i.p.) treated with 1 mg CdCl2/kg/day. Testicular Cd deposition was noticed from the 1st day. After 10 and 21 days, copper (Cu) and iron (Fe) increased by 60-109% and 43-67%, respectively, while zinc (Zn) decreased by 24-33%. During 121 days of the exposure, decrease in testicular total superoxide dismutase (SOD) and total glutathione-s-transferase (GST) activities occurred gradually by 30-78% and 15-84%, respectively, while superoxide anion radical (O-2(center dot-)) increased gradually by 114-271%. After 10-21 days, decrease in testicular catalase (CAT) activity appeared by 13-31%. After 21 days, malondialdehyde (MDA) decreased by 44% and the ratio of oxidized glutathione/reduced glutathione (GSSG/GSH) increased by 130% in testes of the rats exposed to Cd. Additionally, decreased testicular testosterone level and the relative testes mass, along with induced microscopic and macroscopic changes were occured, what can be explained as the consequence of instantly developed OS, impaired essential metals status and Cd testicular deposition.

AB  - Diquat (DQ) neurotoxicity mechanisms are unknown, although, it's systemic toxicity is mediated by free radical reactions. The role of glutathione cycle was assessed by glutathione reductase (GR) applied in the pre-treatment of DQ poisoning. Wistar rats were used and tested compounds were administered intrastriatally (i.s.) in one single dose. Total glutathione (tGSH), glutathione disulfide (GSSG) and glutathione peroxidase (GPx) were measured in the vulnerable brain regions (VBRs) (striatum, hippocampus and cortex), at 30 minutes, 24 hours and 7 days post treatment. Results from the intact and the sham operated groups were not statistically different. Rapid spatial spreading of oxidative stress was confirmed in the examined VBRs.. Mortality (30-40%, within 24hrs) and signs of lethargy were observed in the DQ group. Activity of GPx activity was elevated and GSSG/GSH was higher in the examined VBRs during the experiment, compared to the controls. The i.s. pre-treatment with GR achieved neuroprotective role against DQ induced neurotoxicity, based on animal survival, absence of lethargy and decreased GPx activity and GSSG/GSH in the examined VBRs during the experiment, compared to the DQ group. Our results confirmed that oxidation of GSH was the reason for the reduced antioxidative defense against DQ neurotoxicity.

AB  - Introduction: Contact herbicide diquat (DQ), redox cycling compound, mediates its systemic toxicity throughout the enlarged production of free radicals.

Objective: The objectives of the study were to examine the ability of DQ to induce oxidative stress (OS) and/or nitrosative stress (NS) upon intrastriatal (i.s.) administration and to investigate the role of nitric oxide (NOx) using NG-nitro-L-arginine methyl ester (L-NAME), a non-selective inhibitor of nitric oxide synthase (NOS) in the pretreatment of DQ i.s. administration. Material and Methods: The experiment was conducted on Wistar rats, randomly divided in experimental groups, receiving different treatments i.s. applied. Parameters of OS/NS such as: superoxide anion radical (O-2(center dot-)), superoxide dismutase (SOD), malondialdehyde (MDA) and nitrates (NO3-) were measured in the cortex (bilaterally), at 30th min, 24 hours and 7 days after the treatments. Results: Lethargy and high mortality rate were observed only in the DQ group (within 24 hours and 2-3 hours, respectively) after awakening from anesthesia. Markedly increased production of NOx and O-2(center dot-) along with elevated lipid peroxidation altogether contributed to DQ neurotoxicity. The most importantly, the L-NAME i.s. pretreatment protected treated animals from dying and diminished OS/NS response against DQ-induced neurotoxicity.

AB  - In this study we examined if the response of the cortex against diquat (DQ), intrastriatally (i.s.) applied to Wistar rats, was mediated by oxidative/nitrosative stress (OS/NS). In particular, we were focused on the glutathione (GSH) antioxidative role, thus we applied i.s. glutathione reductase (GR) in the pre-treatment of DQ administration. Superoxide anion radical (O2 •-), nitrate (NO3 -), malondialdehyde (MDA) and superoxide dismutase (SOD), were measured in ipsi- and contra- lateral sides of the cortex, at 30 minutes, 24 hours and 7 days post treatment. The redox balance was not significantly changed in the cortex of sham operated and intact groups. Also, no differences were observed between the ipsi- and contra- lateral side of the cortex. Lethargy and mortality (30-40%) of the animals in the DQ group within 24 hrs, coincided with rapidly developed lipid peroxidation supported by OS/NS upon i.s. DQ administration. Strong redox potential of DQ probably resulted in a huge deprivation of molecular oxygen. The pretreatment with GR acted neuro-protectively, based on animal survival and absence of lethargy, although, lipid peroxidation was not developed in the GR+DQ group, OS was documented by a high concentration of O2 •- (within 24 hrs), descending and eventually inhibiting SOD activity (at 7 days).
AB  - U ovoj studiji smo ispitali da li je oksidativni/nitrosativni stres (OS/NS), uključen u odgovor korteksa Wistar pacova nakon intrastrijatalne (i.s.) izloženosti dikvatu (DK). Posebno smo ispitivali značaj antioksidativne uloge glutationa (GSH), zbog čega smo primenili glutation reduktazu (GR) u predtretmanu davanja DK. Superoksid anjon radikal (O2•¯), nitrati (NO3¯), malondialdehid (MDA) i superoksid dismutaza (SOD), su mereni u obostranom korteksu (ipsi- i kontrastrana), nakon 30 minuta, 24 sati i 7 dana od tretmana. Redoks balans se nije značajno promenio u korteksu lažno operisanih i netretiranih pacova. Takođe, ne postoji statistički značajna razlika između ipsi- i kontra- strane korteksa.

Visok redoks potencijal DK verovatno rezultira opsežnim utroškom molekularnog kiseonika.

AB  - Most commonly observed central nervous system (CNS) effects induced by systemic toxicity of herbicide diquat (DQ) are general depression and lethargy. Generally, it is accepted that DQ exerts its toxicity through the production of superoxide anion radical (O2 ●-) during its redox metabolism in the presence of molecular oxygen, which further initiates radical chain reaction, contributing developing of oxidative stress (OS) as well. Mechanisms of DQ neurotoxic effect is not rationalized till now. The objective of the study was to examine whether OS contributes to DQ neurotxicity. For this purpose, male Wistar rats were intrastriataly (i.s.) treated with DQ and oxidative status parameters such as: superoxide anion radical (O2 ●-); nitrates (NO3 -), as a final metabolite of reactive nitogen species; malondialdehyde (MDA), an indicator of lipid peroxidation; activity of superoxide dismutase (SOD); glutathione peroxidase (GPx), and glutathione (GSH), were measured in the hippocampus at 30 minutes, 24 hours and 7 days post treatment. Noteworthy, mortality rate (30 - 40 %) was observed in the group of rats treated with DQ, within 2-3 hours after awakening from anesthesia. Additionally, lethargy was the only neurological symptom observed in that group. Analyzed parameters indicate that OS mediates DQ neurotxicity, which is documented with significant increase of lipid peroxidation.

Target organs of systemic effect of PQ poisoning are lung and kidney. The mechanism of PQ-induced neurotoxicity is not elucidated till now. The objective of our study was to examine the role of nitric oxide (NOx) in PQ-induced neurotoxicity, primarily focusing on glutathione cycles [total glutathione content (GSH) and glutathione peroxidase (GPx) activity]. In order to investigate the role of NOx in oxidative stress (OS) and/or nitrosative stress (NS) response to PQ neurotoxicity, we used NG-nitro-L-arginine methyl ester (L-NAME), a non-selective inhibitor of nitric oxide synthase (NOS) in the pretreatment of PQ administration. Study was conducted on Wistar rats randomly divided in groups (n=8 for controls and n=24 for experimental groups) depending on the applied treatments. The tested compounds were intrastriatally (i.s.) administered. Measuring of GSH content and GPx activity was performed at 30 min, 24 hours and 7 days after treatments. Parkinsonism’s like symptoms were observed only in the group of rats treated with PQ. The L-NAME protected animals from PQ-induced neurotoxicity, which could be concluded from the absence of Parkinsonism’s like symptoms and reduced OS/NS response in the striatum of rats pretreated with L-NAME.

Parkinsonizam je kao simptom primećen samo u grupi pacova tretiranih PK - om. L-NAME je ispoljio zaštitni efekat kod životinja kod kojih je i.s. davan PK, što bi se moglo zaključiti na osnovu odsustva simptoma parkinsonizma i smanjenog OS/NS odgovora u strijatumu u grupi pretretiranoj sa L-NAME.",
