AB  - Женке пацова имају хормонски контролисан еструсни циклус који изазива регуларне цикличне ткивне и ћелијске промене. Стога, експерименти који се изводе на женкама треба да укључују проверу фазе циклуса и рад на јединкама које су у истој фази. Уобичајено је да се узимају женке у еструсу, али како еструсна фаза траје 15-24 h, женке третиране у еструсу после 6 h ће бити и даље у еструсу у већини случајева, али већ после 24 h су у метаеструсу. Наши претходни резултати показују да ефекти на женкама пацова зависе од фазе циклуса када је апликација фармаколошки активним агенсом урађена. Како је изоловани утерус један од фармаколошких ex vivo модела избора испитивања деловања фармаколошки активних супстанци, укључујући и редокс активне, промене у утерусу директно подложне цикличности могу утицати на ефективност учинка, те и давати варијабилне резултате активности. Стога смо у овом раду мерили активност антиоксидативних ензима (SOD, CAT, GSH-Px и GR) у утерусу у различитим фазама еструсног циклуса. Утеруси у еструсу имају нижу SOD2 и вишу GSH-Px активност у поређењу са другим фазама. Активност GR у еструсу и проеструсу су биле више у поређењу са метаеструсом и диеструсом. Ове промене су у вези и са хормоналним и са редокс статусом утеруса током циклуса. Наши резултати показују да физиолошки, а посебно редокс одговор на екстерне стимулусе може бити другачији у зависности од фазе еструсног циклуса.
AB  - Ženke pacova imaju hormonski kontrolisan estrusni ciklus koji izaziva regularne ciklične tkivne i ćelijske promene. Stoga, eksperimenti koji se izvode na ženkama treba da uključuje proveru faze ciklusa i rad na jedinkama koje su u istoj fazi. Uobičajeno je da se uzimaju ženke u estrusu, ali kako estrusna faza traje 15-24 h, ženke tretirane u estrusu posle 6 h će biti i dalje u estrusu u većini slučajeva, ali već posle 24 h su u metaestrusu. Naši prethodni rezultati pokazuju da efekti na ženkama pacova zavise od faze ciklusa kada je aplikacija farmakološki aktivnim agensom urađena. Kako je izolovani uterus jedan od farmakoloških ex vivo modela izbora ispitivanja delovanja farmakološki aktivnih supstanci, uključujući i redoks aktivne, promene u uterusu direktno podložne cikličnosti mogu uticati na efektivnost učinka, te i davati varijabilne rezultate aktivnosti. Stoga smo u ovom radu merili aktivnost antioksidativnih enzima (SOD, CAT, GSH-Px и GR) u uterusu u različitim fazama estrusnog ciklusa. Uterusi u estrusu imaju nižu SOD2 i višu GSH-Px aktivnost u poređenju sa drugim fazama. Aktivnost GR u estrusu i proestrusu su bile više u poređenju sa metaestrusom i diestrusom. Ove promene su u vezi i sa hormonalnim i sa redoks statusom uterusa tokom ciklusa. Naši rezultati pokazuju da fiziološki, a posebno redoks odgovor na eksterne stimuluse može biti drugačiji u zavisnosti od faze estrusnog ciklusa.

AB  - Background and PurposeHydrogen sulphide reduces uterine contractility
   and is of potential interest as a treatment for uterine disorders. The
   aim of this study was to explore the mechanism of sodium sulphide
   (Na2S)-induced relaxation of rat uterus, investigate the importance of
   redox effects and ion channel-mediated mechanisms, and any interactions
   between these two mechanisms.
   Experimental ApproachOrgan bath studies were employed to assess the
   pharmacological effects of Na2S in uterine strips by exposing them to
   Na2S with or without Cl- channel blockers (DIDS, NFA, IAA-94,
   T16Ainh-A01, TA), raised KCl (15 and 75mM), K+ channel inhibitors
   (glibenclamide, TEA, 4-AP), L-type Ca2+ channel activator (S-Bay K
   8644), propranolol and methylene blue. The activities of antioxidant
   enzymes were measured in homogenates of treated uteri. The expression of
   bestrophin channel 1 (BEST-1) was determined by Western blotting and
   RT-PCR.
   Key ResultsNa(2)S caused concentration-dependent reversible relaxation
   of spontaneously active and calcium-treated uteri, affecting both
   amplitude and frequency of contractions. Uteri exposed to 75mM KCl were
   less sensitive to Na2S compared with uteri in 15mM KCl. Na2S-induced
   relaxations were abolished by DIDS, but unaffected by other modulators
   or by the absence of extracellular HCO3-, suggesting the involvement of
   chloride ion channels. Na2S in combination with different modulators
   provoked specific changes in the anti-oxidant profiles of uteri. The
   expression of BEST-1, both mRNA and protein, was demonstrated in rat
   uteri.
   Conclusions and ImplicationsThe relaxant effects of Na2S in rat uteri
   are mediated mainly via a DIDS-sensitive Cl--pathway. Components of the
   relaxation are redox- and Ca2+-dependent.

AB  - Dimethyl sulfoxide (DMSO) is a widely used solvent and cryoprotectant that can cause impaired blood flow, reduction in intracranial pressure, tissue edema, inflammatory reactions, inhibition of vascular smooth muscle cell migration and proliferation, processes which can lead to atherosclerosis of the coronary, peripheral and cerebral circulation. Although the adverse effects are rare when DMSO is administered in clinically established concentrations, there is no safe antagonist for an overdose. In this work, we treated isolated spontaneous and calcium-induced contractile active rat uteri (Wistar, virgo intacta), with DMSO and fullerenol C-60(OH)(24) nanoparticle (FNP) in DMSO. FNP is a water-soluble derivative of fullerene C-60. Its size is a 1.1 nm in diameter and is a very promising candidate for a drug carrier in nanomedicine. FNP also displays free radical scavenging activity. DMSO decreased both spontaneous and calcium-induced contractions. In contrast, FNP only decreased spontaneous contraction. FNP decreased copper-zinc superoxide dismutase activity and prevented the DMSO-induced increase in glutathione reductase activity. Atomic force microscopy detected that FNP aggregated with calcium ions. Our results indicate that FNP has properties that make it a good candidate to be a modulator of DMSO activity which could minimize side effects of the latter.

AB  - Background: Mutated copper, zinc-containing superoxide dismutase (SOD1) may self-aggregate, an event that could also be an initial cause of motor neuron malfunction leading to disease onset. The effects of human mutated SOD1 protein from the blood of familial amyotrophic lateral sclerosis (FALS) patients bearing Leu144Phe (L144F) mutation were compared to wild-type (WT) human SOD1 derived from healthy examinees, for enzymatic activity and the effects on isometric contractions of non-vascular smooth muscle. Methods: We isolated WT and L144F SOD1 enzymes from eight patients with FALS, L144F mutation in exon 5 and eight healthy controls. We then investigated SOD1 activities in the obtained samples by the adrenaline method and profiled them electrophoretically. Finally, we applied WT and L144F SOD1 on the isolated rat uterus. Results: L144F SOD1 showed lower superoxide-dismutating activity compared to WT human SOD1. We found that, in contrast to WT human SOD1, mutated L144F does not induce smooth muscle relaxation. Conclusions: Our data suggest that the lack of relaxation of muscle tonus in the presence of mutated SOD1 may have pathogenic feedback effects in FALS.

Dalje smo ispitivali aktivnost SOD1 u dobijenim uzorcima adrenalinskom metodom i elektro-foretski ih profilisali. Konačno, izolovanu WT i L144F SOD1 aplicirali smo na izolovani uterus pacova. Rezultati: Aktivnost L144F SOD1 je statistički značajno manja (p<0,05) u poređenju sa aktivnosti WT SOD1 zdravih kontrola. L144F ne izaziva relaksaciju glatkog mišića, kao sto je to slučaj sa WT SOD1. Zaključak: Naši rezultati pokazuju da izostanak relaksacije mišićnog tonusa u prisustvu mutirane SOD1 može imati štetni povratni efekat kod FALS pacijenata.

AB  - Warfarin affects mainly vitamin K dependent (VKD) processes, but the effects on some non-VKD-related activities such as tumor growth inhibition and mononuclear cell-mediated immune reactions were shown as well. In this study, the effect of subchronic (30 days) oral warfarin (0.35 mg/l and 3.5 mg/l) intake on peripheral blood granulocytes in rats was investigated. Increase in prothrombin and partial thromboplastin time at high warfarin dose reflected its basic activity. Priming effect for respiratory burst was noted at both warfarin doses, while only high warfarin dose resulted in priming for adhesion, the rise in intracellular myeloperoxidase content/release and stimulation of nitric oxide production. Differential effects of high warfarin dose were noted on granulocyte cytokines IL-6 (lack of the effect), TNF-alpha (decreased release and mRNA expression) and IL-12 (increase in mRNA for IL-12 subunits p35 and p40). Changes in granulocytes seems not to rely on mitogen activated kinases p38 and ERK. Warfarin intake was associated with an increase in circulating IL-6, fibrinogen and haptoglobin and with changes in the activity of erythrocyte antioxidant enzymes superoxide dismutase and catalase. The effects of oral warfarin intake on peripheral blood granulocytes demonstrated in this study might be relevant for oral anticoagulant therapy strategies in humans. (C) 2012 Elsevier Ltd.

AB  - Tianeptine is a novel anti-depressant with an efficacy equivalent to that of classical anti-depressants. Additional beneficial effects include neuroprotection, anti-stress and anti-ulcer properties whose molecular mechanisms are still not completely understood but may involve changes in the anti-oxidant defence system. Herein, we have studied the effects of tianeptine on both contractile activity of isolated rat uteri and components of the endogenous anti-oxidative defence system. Tianeptine-induced dose-dependent inhibition of both spontaneous and Ca2+-induced contraction of uterine smooth muscle. The effect was more pronounced in the latter. Tianeptine treatment increased glutathione-peroxidase (GSH-Px) and catalase (CAT) activities in spontaneous and Ca2+-stimulated uteri. A significant decrease in glutathione-reductase (GR) activity in both spontaneous and Ca2+-induced uterine contractions after tianeptine treatment indicated a reduction in reduced glutathione and consequently a shift toward a more oxidised state in the treated uteri. In spontaneously contracting uteri, tianeptine caused a decrease in copper-zinc SOD (CuZnSOD) activity. Tianeptine's anti-depressant effects may be accomplished by triggering a cascade of cellular adaptations including inhibition of smooth muscle contractility and an adequate anti-oxidative protection response.

AB  - Fullerene (C60) is the carbon allotrope and as its derivatives already has a significant
impact on biomedical nanotechnology. The potential of nanoparticles is large but one of the
most relevant biological features of fullerene is its application as a biomarker in molecular
diagnostics. Polyhidroxylated fullerene derivatives have been shown to display a wide range
of biological effects. Fullerenol C60(OH)24, as a soluble derivative of fullerene C60, attracts the
attention of a number of researchers. The most studied features of fullerenol are
photosensitization and the ability to quench various free radicals, behaving as a free radical
“sponge” or free radical scavenger. Anitproliferative and anti-cancer properties of this
substance are also in the spotlight. Due to its specific structure that resembles a soccer ball,
fullerenol is a candidate for a drug carrier. This could enable specific action on target cells or
tissue. Ability of fullerenol to interact with dsDNK has also been demonstrated, which is very
important in understanding the penetration of nanoparticles through the cell membrane and
their intracellular activities.
 Potentially wide application of fullerenol in biomedicine requires extensive
pharmacological and toxicological investigations. Pharmacological tests and direct
pharmacological effects obtained from application of fullerenol on isolated organs that
possess smooth musculature were investigated only sporadically.
 On the other hand, dimethyl sulfoxide (DMSO) has long been investigated but is,
according to some, still insufficiently represented in the pharmacology. Besides being an
excellent solvent, topical analgetic and drug carrier, DMSO has the ability to remove free
radicals and is considered to have positive effects on the damage of cardiovascular system,
central nervous system, renal disease, defects in the structure of connective tissue etc.
 Both fullerenol and DMSO can cause changes in the contractility of smooth muscles,
which is extremely important for their potentially wider application in pharmacology.
 Ileum, as a part of the digestive tract is an important model system for the investigation of
a substance that could potentially be used in pharmacology. Uterus contractility, microflora and the activity of antioxidative enzymes change during menstrual cycle. Investigated
substances can change parameters of contraction, such as: frequency, amplitude, duration and
direction.

 Ispitivane supstance mogu uticati na promene parametara kao što su: frekvenca,
amplituda, trajanje i smer propagacije kontrakcija., Fullerene (C60) is the carbon allotrope and as its derivatives already has a significant
impact on biomedical nanotechnology. The potential of nanoparticles is large but one of the
most relevant biological features of fullerene is its application as a biomarker in molecular
diagnostics. Polyhidroxylated fullerene derivatives have been shown to display a wide range
of biological effects. Fullerenol C60(OH)24, as a soluble derivative of fullerene C60, attracts the
attention of a number of researchers. The most studied features of fullerenol are
photosensitization and the ability to quench various free radicals, behaving as a free radical
“sponge” or free radical scavenger. Anitproliferative and anti-cancer properties of this
substance are also in the spotlight. Due to its specific structure that resembles a soccer ball,
fullerenol is a candidate for a drug carrier. This could enable specific action on target cells or
tissue. Ability of fullerenol to interact with dsDNK has also been demonstrated, which is very
important in understanding the penetration of nanoparticles through the cell membrane and
their intracellular activities.
 Potentially wide application of fullerenol in biomedicine requires extensive
pharmacological and toxicological investigations. Pharmacological tests and direct
pharmacological effects obtained from application of fullerenol on isolated organs that
possess smooth musculature were investigated only sporadically.
 On the other hand, dimethyl sulfoxide (DMSO) has long been investigated but is,
according to some, still insufficiently represented in the pharmacology. Besides being an
excellent solvent, topical analgetic and drug carrier, DMSO has the ability to remove free
radicals and is considered to have positive effects on the damage of cardiovascular system,
central nervous system, renal disease, defects in the structure of connective tissue etc.
 Both fullerenol and DMSO can cause changes in the contractility of smooth muscles,
which is extremely important for their potentially wider application in pharmacology.
 Ileum, as a part of the digestive tract is an important model system for the investigation of
a substance that could potentially be used in pharmacology. Uterus contractility, microflora and the activity of antioxidative enzymes change during menstrual cycle. Investigated
substances can change parameters of contraction, such as: frequency, amplitude, duration and
direction.",

AB  - Ibogaine has been extensively studied in the last decades in relation to its anti-addictive properties that have been repeatedly reported as being addiction interruptive and craving eliminative. In our previous study we have already demonstrated induction of energy related enzymes in rat brains treated with ibogaine at a dose of 20 mg/kg i.p. 24 and 72 h prior to proteomic analysis. In this study a model organism yeast Saccharomyces cerevisiae was cultivated with ibogaine in a concentration of 1 mg/l. Energy metabolism cluster enzymes glyceraldehyde-3-phosphate dehydrogenase, phosphoglycerate kinase, enolase and alcohol dehydrogenase were induced after 5 h of exposure. This is a compensation of demonstrated ATP pool decrease after ibogaine. Yeast in a stationary growth phase is an accepted model for studies of housekeeping metabolism of eukaryotes, including humans. Study showed that ibogaine's influence on metabolism is neither species nor tissue specific. Effect is not mediated by binding of ibogaine to receptors, as previously described in literature since they are lacking in this model. (C) 2009 Elsevier B.V. All rights reserved.

AB  - Background and purpose: The effects of hydrogen peroxide (H(2)O(2)) on uterine smooth muscle are not well studied. We have investigated the effect and the mechanism of action of exogenous hydrogen peroxide on rat uteri contractile activity [spontaneous and calcium ion (Ca2+)-induced] and the effect of such treatment on anti-oxidative enzyme activities. Experimental approach: Uteri were isolated from virgin Wistar rats and suspended in an organ bath. Uteri were allowed to contract spontaneously or in the presence of Ca2+ (6 mM) and treated with H(2)O(2) (2 mu M-3 mM) over 2 h. Anti-oxidative enzyme activities (manganese superoxide dismutase-MnSOD, copper-zinc superoxide dismutase-CuZnSOD, catalase-CAT, glutathione peroxidase-GSHPx and glutathione reductase-GR) in H(2)O(2)-treated uteri were compared with those in uteri immediately frozen after isolation or undergoing spontaneous or Ca2+-induced contractions, without treatment with H(2)O(2). The effect of inhibitors (propranolol, methylene blue, L-NAME, tetraethylamonium, glibenclamide and 4-aminopyridine) on H(2)O(2)-mediated relaxation was explored. Key results: H(2)O(2) caused concentration-dependent relaxation of both spontaneous and Ca2+-induced uterine contractions. After H(2)O(2) treatment, GSHPx and MnSOD activities were increased, while CuZnSOD and GR (In Ca2+-induced rat uteri) were decreased. N omega-nitro-L-arginine methyl ester antagonized the effect of H(2)O(2) on Ca2+-induced contractions. H(2)O(2)-induced relaxation was not affected by propranolol, potentiated by methylene blue and antagonized by tetraethylamonium, 4-aminopyridine and glibenclamide, with the last compound being the least effective. Conclusions and implications: H(2)O(2) induced dose-dependent relaxation of isolated rat uteri mainly via changes in voltage-dependent potassium channels. Decreasing generation of reactive oxygen species by stimulation of anti-oxidative pathways may lead to new approaches to the management of dysfunctional uteri.

AB  - Eukaryotic cell survives in predominantly reduced conditions. Homeostasis of cellular redox system is an imperative of cell surviving and its normal metabolism. ROS are well recognized for playing a dual role as both deleterious and beneficial species, since they can be either harmful or beneficial to living systems. These species are mutagenic compounds known to lead to DNA damage, favor cell transformation, and contribute to the development of a variety of malignant diseases. All the effects of oxidants are influenced by the cellular antioxidant defenses. This multilayer system consists of low molecular weight components and several antioxidant enzymes. Superoxide dismutases (SODs) are the only enzymes dismuting superoxide radicals. Mitomycin C, a cross-linking agent, demonstrated genotoxicity in all in vitro and in vivo test systems in mammalian cells and animals. Water-soluble fullerenes are well known as cytotoxic agents for many cell lines in vitro. At the other side, fullerenols are good free radical scavengers and antioxidants both in vitro and in vivo. This paper investigates the effects of fullerenol on survival and fullerenol/ /mytomicine (MMC) treatment on superoxide-dismutase (SOD) activity in CHO-K1 cells. Samples were treated 3 and 24 h with fullerenol (C60(OH)24) at concentration range 0.01-0.5 mg/mL and survival was monitored with dye exclusion test (DET). The activity of total SOD was estimated in samples treated with chosen concentrations of fullerenol and MMC (0.5 and 0.1 mg/mL) after 3 and 24 h of cell incubation. Increasing of C60(OH)24 concentration leads to decreasing of percent of surviving cells 3 and 24 h after incubation. The activity of total SOD enhanced with higher concentration of fullerenol, while decreased in the highest concentration at both experimental points. In samples treated with MMC, as well as in samples treated with fullerenol (0.0625 mg/mL) + MMC was noticed boost in total SOD activity in comparison with controls. Treatment with fullerenol decreased SOD activity in rest of samples treated with MMC. Decreased activity of superoxide-dismutase in almost all samples treated with fullerenol and MMC might be contributed to antioxidative properties of fullerenol. Increased enzyme level at concentration of 0.0625 mg/mL may be due to its prooxidative activity.

AB  - Protamine sulphate (PS) effect on spontaneous and calcium-induced rhythmic contractions of isolated virgin rat uteri was studied. PS caused dose-dependent relaxation of both types of contractions (two-way ANOVA, significant dose effects). Pretreatment with NG-nitro-L-arginine methyl ester (L-NAME; 10(-5) mol/l), methylene blue (MB; 0.9 x 10(-6) mol/l) or propranolol (1.7 x 10(-5) mol/l) enhanced PS-mediated uterine muscle relaxation of spontaneous contractions. Dose-dependent relaxation of spontaneous active isolated rat uterus with PS was lower in uteri pretreated with single dose of tetraethylammonium (TEA; 6 x 10(-3) mol/l), glibenclamide (2 x 10(-6) mol/l) and 4-aminopyridine (4-AP; 10(-3) mol/l). Calcium-induced activity of the isolated rat uterus pretreated with the same concentration of L-NAME, MB, or propranolol modified the kinetic of PS-induced relaxation without changes in EC(50) values. Pre-treatment with glibenclamide, TEA and 4-AP significantly reduce PS relaxing effect of calcium-induced activity and according to EC(50) values the order of magnitude was glibenclamide > TEA > 4-AP. PS is mixture of polyamines and may activate different signal-transduction pathways. Our results cleary demonstrate that in uterine smooth muscle PS act dominantly through potassium chanels and marginaly through beta-adrenergic receptos or nitric oxide-dependent pathways.

Calcium-induced activity of the isolated rat uterus pretreated with the same concentration of L-NAME, MB, or propranolol modified the kinetic of PS-induced relaxation without changes in EC(50) values. Pre-treatment with glibenclamide, TEA and 4-AP significantly reduce PS relaxing effect of calcium-induced activity and according to EC(50) values the order of magnitude was glibenclamide > TEA > 4-AP. PS is mixture of polyamines and may activate different signal-transduction pathways. Our results cleary demonstrate that in uterine smooth muscle PS act dominantly through potassium chanels and marginaly through beta-adrenergic receptos or nitric oxide-dependent pathways.",
