AB  - Aluminium may have an important role in the
   aetiology/pathogenesis/precipitation of Alzheimer's disease. Because
   green tea (Camellia sinensis L.) reportedly has health-promoting effects
   in the central nervous system, we evaluated the effects of green tea
   leaf extract (GTLE) on aluminium chloride (AlCl3) neurotoxicity in rats.
   All solutions were injected into the cornu ammonis region 1 hippocampal
   region. We measured the performance of active avoidance (AA) tasks,
   various enzyme activities and total glutathione content (TGC) in the
   forebrain cortex (FbC), striatum, basal forebrain (BFb), hippocampus,
   brain stem and cerebellum. AlCl3 markedly reduced AA performance and
   activities of cytochrome c oxidase (COX) and acetylcholinesterase (AChE)
   in all regions. It decreased TGC in the FbC, striatum, BFb, hippocampus,
   brain stem and cerebellum, and increased superoxide dismutase activity
   in the FbC, cerebellum and BFb. GTLE pretreatment completely reversed
   the damaging effects of AlCl3 on AA and superoxide dismutase activity,
   markedly corrected COX and AChE activities, and moderately improved TGC.
   GTLE alone increased COX and AChE activities in almost all regions. GTLE
   reduces AlCl3 neurotoxicity probably via antioxidative effects and
   improves mitochondrial and cholinergic synaptic functions through the
   actions of (-)-epigallocatechin gallate and (-)-epicatechin, compounds
   most abundantly found in GTLE. Our results suggest that green tea might
   be beneficial in Alzheimer's disease. Copyright (c) 2013 John Wiley \&

AB  - Background/Aim. Despite years of research in a number of experimental models the question whether nitric oxide (NO) and methylene blue (MB) have pro- or anticonvulsant effects remains to be fully resolved. Methods. In adult Wistar rats the influence of a nonselective inhibitor of nitric oxide synthase NG-nitro-L-arginine methyl ester (LNAME, 10µg) on clinical and biochemical effects of MB (10µg) given before the intraperitoneally administered chemical convulsant pentylenetetrazole (PTZ, 80 mg/kg) was examined. MB and L-NAME were applied intracerebroventricularly. PTZ application was followed by a 4- minute observation time, after which rats were sacrificed and elements of oxido-reductive balance were measured in a crude mitochondrial fraction of forebrain cortex, hippocampus and striatum. Results. Convulsive responses (forelimb dystonia - FLD, generalised clonic- and clonic-tonic convulsions - GCC and GCTC respectively) were observed in all rats received PTZ, together with significantly decreased lipid peroxidation in the forebrain cortex and striatum and increased superoxide dismutase activity in the hippocampus, in comparison to controls (saline treated). It was registered anticonvulsant effects of L-NAME pretreatment. However, these effects were insignificant. In the hippocampus of these animals there was decreased lipid peroxidation (p < 0.01, p < 0.05 vs saline-treated and PTZ-treated rats, respectively) and reverted PTZ-induced increase of superoxide dismutase activity. But MB individually pretreatment significantly decreased the incidence of CTCs and GCCs (FLD: p = 0.0513), prolonged the convulsive latent time for FLD, GCTCs and GCCs, in all the examined brain regions increased lipid peroxidation and decreased the level of superoxide anion. Administration of L-NAME 10 minutes before MB reverted all MB-evoked clinical and biochemical effects. Conclusion. Methylene blue applied individually before PTZ has strong anticonvulsant effects that were eliminated by L-NAME pretreatment. These effects and changed biochemical parameters in the brains of animals treated by L-NAME before MB in comparison to MBtreated group suggest involvement of NO in MB's effects in the animal model of PTZ-evoked convulsions.
AB  - Uvod/Cilj. I pored višegodišnjeg istraživanja na različitim eksperimentalnim modelima, nije potpuno odgovoreno na pitanje da li azot-oksid (NO) i metilen plavo (MP) deluju konvulzivno ili antikonvulzivno. Metode. Na odraslim pacovima Vistar soja ispitivan je uticaj NG-nitro-L-arginin metil estra (L-NAME, 10 µg), neselektivnog inhibitora azot oksid sintaze, na kliničke i biohemijske efekte metilen plavog (MP, 10 µg) datog intracerebroventrikularno pre hemijskog konvulziva pentilentetrazola (PTZ, 80 mg/kg), primenjenog intraperitonealno. Pacovi su posmatrani četiri minuta posle davanja PTZ-a, posle čega su žrtvovani i u neprečišćenoj mitohondrijskoj frakciji prednjeg mozga, hipokampusa i strijatuma određivani su parametri oksidoreduktivne ravnoteže. Rezultati. Posle primene PTZ-a, konvulzivni odgovor (distonija prednjih nogu - DPN, generalizovane klonične - GKK i generalizovane kloničnotonične konvulzije - GKTK) bio je ispoljen kod svih životinja, kao i statistički značajno sniženje lipidne peroksidacije u kori prednjeg mozga i strijatuma, i povećanje aktivnosti superoksid dizmutaze (SOD) u hipokampusu, u poređenju sa kontrolnom grupom (dobila fiziološki rastvor NaCl). Registrovani su antikonvulzivni efekti L-NAME koji nisu bili statistički značajni. U hipokampusu ovih životinja bila je snižena lipidna peroksidacija (p < 0,01 u poređenju sa kontrolnom grupom, p < 0,05 u poređenju sa životinjama koje su dobile PTZ), kao i aktivnost SOD u poređenju sa životinjama koje su dobile PTZ. Samo metilen plavo dovelo je do statistički značajnog smanjenja incidencije GKK I GKTK (DPN: p = 0,0513), produžilo je latentni period DPN, GKK i GKTK, a u svim ispitivanim strukturama mozga bila je povećana lipidna peroksidacija i smanjen nivo superoksidnog anjona. Svi klinički i biohemijski efekti izazvani primenom MP u potpunosti su odstranjeni primenom L-NAME 10 minuta pre davanja MP. Zaključak. Metilen plavo, dat samostalno pre PTZ, ispoljio je snažne antikonvulzivne efekte. Nestanak ovih efekata i izmenjeni biohemijski parametri u mozgovima pacova koji su pre MP dobili L-NAME, sugerišu da je NO uključen u efekte MP ispoljene na životinjskom modelu konvulzija izazvanih primenom PTZ-a.

AB  - The present experiment was carried out to determine the effectiveness of nitric oxide synthase (NOS) inhibitor (L-NAME) in elevating the toxicity of AlCl3 on nitrite concentration and acetylcholine esterase activity of Wistar rats. Animals were killed 10 min and 3 days after the treatment and the forebrain cortex and striatum were removed. The results show that AlCl3 exposure promotes oxidative stress in different neural areas. The biochemical changes observed in neuronal tissues show that aluminium acts as a pro-oxidant, while NOS inhibitor exerts as antioxidant action in AlCl3-treated animals. In the present study, active avoidance learning was significantly impaired after AlCl3 injection, while pretreatment with L-NAME prevented the behavioural deficits caused between the 8th and 12th day after intrahippocampal application of neurotoxin. Our data suggest that aluminium may cause learning and memory deficits, while the treatment with L-NAME may decrease the oxidative stress and prevent learning and memory deficits caused by AlCl3.

Životinje su dekapitovane 10 minuta ili 3 dana nakon tretmana i izolovani su kora prednjeg mozga i strijatum. Rezultati ukazuju da AlCl3 pokreće oksidativni stres u različitim regionima mozga. Biohemijske promene opisane u neuronskom tkivu ukazuju da aluminijum deluje kao prooksidans, dok inhibitor NOS ima antioksidativno dejstvo kod životinja tretiranih AlCl3. Reakcija aktivnog izbegavanja je bila znatno poremećena nakon aplikacije AlCl3, dok se davanjem L-NAME sprečavaju poremećaji ponašanja uzrokovani između 8. i 12. dana posle intrahipokampusne primene neurotoksina. Naši rezultati ukazuju da aluminijum može dovesti do smetnji u procesima učenja i pamćenja, dok tretman sa L-NAME smanjuje oksidativni stres i sprečava promene u učenju i pamćenju uzrokovane AlCl3.

AB  - Certain types of convulsions may lead to multiorgan dysfunction. We investigated whether the chemoconvulsant pentylenetetrazole (PTZ) could influence energy synthesis in the liver besides evoking convulsions in adult male Wistar rats. In 80% of the rats PTZ (100 mg/kg body weight, administered intraperitoneally - i.p.) evoked generalised clonic convulsions (GCCs) and in 60% of the rats generalised clonic-tonic convulsions (GCTCs) within 4 min after its administration. Cytochrome c oxidase activity was simultaneously reduced approximately three-fold compared to 0.9% NaCl-treated (control) rats (p < 0.01). Midazolam administered before PTZ was an excellent anti-convulsant especially against GCCs (p < 0.05). However, it did not protect against the decrease in cytochrome c oxidase activity induced by PTZ. In contrast to midazolam, pretreatment with L-arginine did not prevent PTZ-evoked convulsions. However, it offered some protection against the PTZ-mediated reduction in cytochrome c oxidase activity. Our results open new avenues of research that will focus on the mechanisms of action of PTZ, midazolam and L-arginine with particular reference to their direct and/or indirect effects on liver function.

AB  - Oxidative stress development in different brain structures and the influence of nitric oxide (NO) overproduction during sepsis was investigated using male Wistar rats. Rats were subjected to cecal ligation and puncture (CLP) or were sham-operated. To evaluate the source of NO production, 30 min before the operation septic and control animals were treated with single intraperitoneal doses of NO synthase (NOS) inhibitors: L-NAME and aminoguanidine (AG) (10, 30 or 90 mg/kg) and 7-nitroindazole (7-NI) (30 mg/kg). The concentration of GSH in the cortex, brain stem, cerebellum, striatum and hippocampus significantly decreased post CLP at both early and late stage sepsis. Lipid peroxidation also occurred in the cortex and cerebellum in late stage sepsis. Pre-treatment with a non-selective NOS inhibitor (L-NAME) and with selective inducible and neuronal NOS inhibitors (AG and 7-NI) revealed benefit effects on the GSH concentrations. Unexpectedly, NOS inhibition resulted in diverse effects on TBARS concentrations, suggesting the importance of specific quantities of NO in specific brain structures during sepsis.

AB  - The present study was aimed at determining the effectiveness of nitric oxide synthase (NOS) inhibitors: N-nitro-L-arginine methyl ester, 7-nitroindazole and aminoguanidine in modulating the toxicity of AlCl3 on superoxide production and the malondialdehyde concentration of Wistar rats. The animals were sacrificed 10 min and 3 days after the treatment and the forebrain cortex was removed. The results show that AlCl3 exposure promotes oxidative stress in different neural areas. The biochemical changes observed in the neuronal tissues show that aluminum acts as pro-oxidant, while NOS inhibitors exert an anti-oxidant action in AlCl3-treated animals.

Životinje su žrtvovane 10 min i 3 dana nakon tretmana i izolovana je kora velikog mozga. Rezultati pokazuju da izlaganje AlCl3 pokreće oksidativni stres u različitim moždanim regionima.

AB  - Although considered to be generally safe, a number of P-lactam antibiotics have been associated with epileptic seizures in humans. Furthermore, some P-lactam antibiotics, including ceftriaxone, are used to evoke convulsions under experimental conditions. Recently it was demonstrated that ceftriaxone increased expression of the glutamate transporter (GLT1) and its biochemical and functional activity in the brain of rodents. GLT1 regulates extracellular concentrations of glutamate, an excitatory amino acid involved in the pathogenesis of seizures and epilepsy. Because of its rapid transfer of glutamate into neurons and adjacent glial cells, GLT1 diminishes glutamate toxicity. We investigated whether ceftriaxone (200 mg/kg body wt) administered intraperitoneally (ip) for 6 days could modify the convulsant effects of pentylenetetrazole (PTZ, 100 mg/kg ip) in inbred male BALBcAnNCR and C57 black (BL)/6 mice aged 4 and 12 weeks. Ceftriaxone pretreatment provided significant protective effects against PTZ-evoked generalized clonic convulsions (GCCs), generalized clonic-tonic convulsions (GCTCs), and convulsion-induced mortality during a period of 30 mins after PTZ administration. The incidence of GCCs, GCTCs, and death was statistically significantly lower for BALBcAnNCR mice of both ages, particularly younger mice. The latency time for each of the three parameters was significantly greater, with the exception of GCCs in adult mice. Protective effects of ceftriaxone were also noticed in adult C57BL/6 mice but not in prepubertal C57BL/6 mice. This is the first demonstration of anticonvulsant effects of ceftriaxone or any other P-lactam antibiotic, which are not uniform across the mouse population. Our results provide new insight into the effects of ceftriaxone, which need further investigation. Exp Biol Med 233:1389-1394, 2008

AB  - In the CNS polyamines can exert opposite effects, depending on the concentration and conditions in the cell. Protective or neurotoxic polyamine effects were documented during seizures and repeated CNS excitation. Intensive research of exogenous polyamines effects during seizures induced by numerous agents did not clear up confusions about the duality of effects and the role of polyamines in seizures. In order to understand polyamine modulatory effects in seizures, the importance of NO and polyamine metabolism interdependence and the possible implication of changes of postulated NO and polyamine equillibrium in seizures, the effects of spermine alone and in combination with L-NAME (NOS inhibitor) on seizures induced by pentazol (PTZ) were investigated. To compare the obtained results, the effects of anticonvulsant midazolam on NO production during seizures were also investigated. Seizures were induced by i.p. application of pentazol (100 mg/kg b.w). Spermine and L-NAME were administered i.p. before PTZ. In the striatum and hippocampus, spermine induced increased NO production (p<0.001) related to values in the group treated by PTZ. Application of L-NAME before spermine and PTZ caused decrease of NO production in comparison with animals treated only by PTZ or spermine and PTZ. L-NAME given before spermine exerts protective effects related to seizures induced by PTZ and to the group treated by spermine, extending the time of seizure symptoms appearance, thus confirming the NO signaling system involvement in spermine effects during seizures. Highly significant PAO activity increase caused by spermine points out the intensified interconversion of spermine into putrescine, in order to maintain the intracellular putrescine concentration. The obtained results prove a strong relationship between the NO signaling system and polyamine metabolism in the brain during seizures and the importance of their changes in this kind of CNS injury.
AB  - U CNS-u poliamini mogu imati dijametralno suprotne efekte, zavisno od njihove koncentracije i uslova u ćeliji. U toku konvulzija i pri ponavljanoj ekscitaciji CNS-a dokazani su i protektivni i neurotoksični efekti poliamina. Intenzivna istraživanja efekata egzogenih poliamina u toku konvulzija izazvanih brojnim agensima in vivo nisu još uvek razjasnila nedoumice o dualitetu efekata i ulozi poliamina u konvulzijama. U cilju razjašnjenja modulatornih efekata poliamina u konvulzijama, značaja povezanosti metabolizma NO i poliamina i mogućnosti implikacije promena postulirane ravnoteže između NO i poliamina u konvulzijama, ispitivani su efekti spermina na konvulzije izazvane pentazolom (PTZ) i produkciju NO, kao i efekti spermina u kombinaciji sa L-NAME (inhibitorom NOS). Radi poređenja dobijenih rezultata, ispitivani su i efekti antikonvulziva midazolama na produkciju NO u toku konvulzija. Konvulzije su izazivane i.p. aplikacijom pentazola (100 mg/kg TM). Spermin i L-NAME su aplikovani i.p. pre PTZ-a. U strijatumu i hipokampusu spermin izaziva povećanu produkciju NO (p<0,001) u odnosu na vrednosti u grupi tretiranoj PTZom. Aplikacija L-NAME pre spermina i PTZ-a izazvala je smanjenje produkcije NO u odnosu na životinje tretirane samo PTZ-om ili sperminom i PTZ-om.

L-NAME, dat pre spermina, ispoljava protektivne efekte u odnosu na konvulzije izazvane pentazolom i grupu tretiranu sperminom, produžavajući vreme pojave simptoma konvulzija, što potvrđuje uključenost NO signalnog sistema u efekte spermina u toku konvulzivne aktivnosti. Visokosignifikantni porast aktivnosti PAO izazvan sperminom ukazuje na intenzivnu interkonverziju poliamina u putrescin u cilju održanja intracelularne koncentracije putrescina.

abstract = "In the CNS polyamines can exert opposite effects, depending on the concentration and conditions in the cell. Protective or neurotoxic polyamine effects were documented during seizures and repeated CNS excitation. Intensive research of exogenous polyamines effects during seizures induced by numerous agents did not clear up confusions about the duality of effects and the role of polyamines in seizures. In order to understand polyamine modulatory effects in seizures, the importance of NO and polyamine metabolism interdependence and the possible implication of changes of postulated NO and polyamine equillibrium in seizures, the effects of spermine alone and in combination with L-NAME (NOS inhibitor) on seizures induced by pentazol (PTZ) were investigated. To compare the obtained results, the effects of anticonvulsant midazolam on NO production during seizures were also investigated. Seizures were induced by i.p. application of pentazol (100 mg/kg b.w). Spermine and L-NAME were administered i.p. before PTZ. In the striatum and hippocampus, spermine induced increased NO production (p<0.001) related to values in the group treated by PTZ. Application of L-NAME before spermine and PTZ caused decrease of NO production in comparison with animals treated only by PTZ or spermine and PTZ. L-NAME given before spermine exerts protective effects related to seizures induced by PTZ and to the group treated by spermine, extending the time of seizure symptoms appearance, thus confirming the NO signaling system involvement in spermine effects during seizures. Highly significant PAO activity increase caused by spermine points out the intensified interconversion of spermine into putrescine, in order to maintain the intracellular putrescine concentration. The obtained results prove a strong relationship between the NO signaling system and polyamine metabolism in the brain during seizures and the importance of their changes in this kind of CNS injury., U CNS-u poliamini mogu imati dijametralno suprotne efekte, zavisno od njihove koncentracije i uslova u ćeliji. U toku konvulzija i pri ponavljanoj ekscitaciji CNS-a dokazani su i protektivni i neurotoksični efekti poliamina. Intenzivna istraživanja efekata egzogenih poliamina u toku konvulzija izazvanih brojnim agensima in vivo nisu još uvek razjasnila nedoumice o dualitetu efekata i ulozi poliamina u konvulzijama. U cilju razjašnjenja modulatornih efekata poliamina u konvulzijama, značaja povezanosti metabolizma NO i poliamina i mogućnosti implikacije promena postulirane ravnoteže između NO i poliamina u konvulzijama, ispitivani su efekti spermina na konvulzije izazvane pentazolom (PTZ) i produkciju NO, kao i efekti spermina u kombinaciji sa L-NAME (inhibitorom NOS).

AB  - An extremely low-frequency magnetic field (50 Hz, 0.5 mT) was used to investigate its possible effect on the brain of adult male Wistar rats following a 7-day exposure. The control rats were sham-exposed. Superoxide dismutase activities and production Of Superoxide radicals, lipid peroxidation, and nitric oxide were examined in the frontal cortex, striatum, basal forebrain, hippocampus, brainstem, and cerebellum. Significantly increased superoxide radical contents were registered in all the structures examined. Production of nitric oxide, which can oppose superoxide radical activities, was significantly increased in some structures: the frontal cortex, basal forebrain, hippocampus, and brainstem. Augmentation of lipid peroxydation was also observed, with significance only in the basal forebrain and frontal cortex, in spite of the significantly increased superoxide dismutase activities and nitric oxide production in the basal forebrain, and increased production of nitric oxide in the frontal cortex. The results obtained indicate that a 7-day exposure to extremely low-frequency magnetic field can be harmful to the brain, especially to the basal forebrain and frontal cortex due to development of lipid peroxidation. Also, high production of superoxide anion in all regions may compromise nitric oxide signaling processes, due to nitric oxide consumption in the reaction with the superoxide radical.

AB  - Exposure to extremely low-frequency magnetic field (ELF-MF, 50 Hz, 0.5 mT) for seven days did not change spontaneous motor activity of rats in the open field compared to sham-exposed animals. Pre-exposure to ELF-MF decreased locomotor and stereotypic activity induced by amphetamine (1.5 mg/kg body weight) and accordingly increased the resting time compared to sham-exposed and amphetamine-treated rats. Vertical activity (rearing) of these two groups was similar. Our results indicate that ELF-MF has different effects on some parameters of amphetamine-induced motor activity, probably due to brain region-specific effects on catecholaminergic systems responsible for movement control.

AB  - Continuous exposure to extremely low-frequency magnetic field (ELF-MF, 50 Hz, 0.5 mT) alone and combined with D-amphetamine (1.5 mg/kg) affected the reduced glutathione content in brain regions of rats. Compared to sham-exposed rats, the glutathione content in the forebrain cortex of the ELFMF-exposed rats decreased (P < 0.001), but this reverted after giving amphetamine upon ELF-MF exposure. In this group, the glutathione content was increased in the brain stem and cerebellum (P < 0.05 compared to the shame-exposed, ELM-MF-exposed, and amphetamine-treated groups). It is suggested that biogenic monoamines are involved in the reduced glutathione changes observed. The changes are not uniform in the brain regions examined.

AB  - It is expected that clinical recovery after surgically induced brain trauma is followed by molecular and biochemical restitution. Seven days after surgery, we investigated whether the plastic cannula implanted in the left brain ventricle of adult Wistar rats (n = 6-7), performed in pentobarbital anesthesia, could influence oxidative stress elements (superoxide anion and lipid peroxidation), as well as the antioxidative system (superoxide dismuthase-SOD). Also, we investigated whether nitric oxide (NO) is involved in these processes. Biochemical analyses was performed in the forebrain cortex, striatum and hippocampus. Clinical recovery was complete seven days after surgery. Thereafter, thirty minutes before decapitation, through the cannula, one group of rats received saline intracerebroventricularly (control group), and the treated group received Nω-nitro-L-arginine methyl ester (L-NAME). The third group was left unoperated and untreated. Before and after the treatments, rectal body temperature was measured. Compared to the untreated group the index of lipid peroxidation was increased in all three brain structures in the group that received saline (p<0.05 to 0.01). Application of L-NAME deteriorated it in the striatum and hippocampus (p<0.01 compared to the both other groups), but the value in the forebrain cortex was similar to the untreated group. Supeoxide anion level was decreased in the L-NAME treated group only in the striatum (p<0.01 compared to control and untreated groups), but SOD was increased in the hippocampus compared to the saline treated group (p<0.05). Seven days after brain surgery in pentobarbital anesthesia, recovery of biochemical disturbances was not parallel to clinical recovery. Long lasting biochemical changes are rather the consequence of brain injury than to pentobarbital anesthesia. In this experimental model, NO had protective effects, acting against lipid per oxidation in the striatum and hippocampus, but not in the forebrain cortex i. e. NO involvement in the free radical processes strongly depends on the observed brain region.
AB  - Posle hirurške intervencije na mozgu, očekuje se paralelizam između kliničkog, sa jedne strane, i molekulskog i biohemijskog oporavka, sa druge strane. Da bi to utvrdili, u tri moždane strukture (kora prednjeg mozga strijatum, hipokampus) odraslih Vistar pacova muškog pola, ispitivali smo promene pojedinih prooksidativnih i antioksdativnih parametara, nastalih posle usađivanja plastične kanile u bočnu komoru mozga, kroz koju su ubrizgavane ispitivane supstance (10pi). Kao opšti anestetik korišćen je pentobarbiton natrijum (0,045 g/kg). Eksperiment je nastavljen sedam dana posle operacije, kada su pacovi bili klinički potpuno oporavljeni. Pre ubrizgavanja 0,9% NaCI jednoj grupi (kontrola) i Nω-nitro-L-arginin metil estra (L-NAME, 10 mikrograma, rastvoren u 0,9% NaCI) drugoj grupi, kao i 30 minuta posle toga, merena je rektalna temperatura kod sve tri grupe pacova (treću su činili intaktni pacovi, 6-7 pacova u svakoj grupi). Porast indeksa lipidne peroksidacije u sve tri moždane strukture operisanih pacova koji su dobili NaCI bio je statistički značajan u odnosu na intaktnu grupu. Ubrizgavanjem L-NAME, ove promene su u strijatumu i hipokampusu postale statistički još izraženije u odnosu na grupu koja je dobila NaCI, dok je u kori prednjeg mozga registrovan sasvim slab porast u odnosu na intaktnu grupu. Istovremeno, ometanje sinteze NO bilo je praćeno statistički značajnim padom superoksidnog radikala u strijatumu u odnosu na obe grupe, i porastom superoksid dizmutaze u hipokampusu u odnosu na grupu koja je dobila NaCI. Telesna temperature je bila normalna kod svih pacova u oba vremena merenja. Dokazano je da ne postoji paralelizam između kliničkog i biohemijskog oporavka posle operacije na mozgu pacova, izvedene u opštoj anesteziji uz primenu pentobarbitona. To je ispoljeno pojačanom lipidnom peroksidacijom sedam dana posle operacije u sve tri ispitivane strukture mozga koji su dobili NaCI. Porast lipidne peroksidacije je najverovatnije posledica mehaničkog oštećenja izazvanog operacijom, pre nego same anestezije. U ovim procesima, NO ima značajnu regulatornu ulogu, pri čemu njegovi efekti nisu podjednako ispoljeni u svim delovima mozga. Njegova snažna antioksidativna svojstva registruju se u hipokampusu i strijatumu ali ne i u kori prednjeg mozga, što govori u prilog selektivne osetljivosti mozga.

AB  - There are a number of acquired blood disorders. They are frequently drug-induced. Besides other blood cell lines, drugs can affect red blood cells, too, and evoke different types of anemias. Many tens of drugs are associated with megaloblastic and different types of hemolytic anemias, and also aplastic one. Establishing causality of such adverse drug reaction is not easy. Pathogenesis of drug-induced anemias are represented by immune-mediated, idiosyncratic, and some other types of reactions. In general, some of them are dose dependent, but the other are not. Epidemiological data about red blood cell dyscrasias associated with drugs are very often unharmonized. Since they are originated by various processes, their prognosis and treatment are not uniform. In the aim to avoid the possibility of over-looking drugs as risk factor in inducing anemias, it is necessary to obtain sufficient information about them by introducing pharmacological anamnesis in patient's medical history as its integral part.
AB  - Sve se veća pažnja obraća na lekove kao potencijalne uzročnike velikog broja poremećaja. Tome doprinosi bolje poznavanje neželjenih efekta lekova. Više desetina lekova može da izazove hematološke poremećaje. Njihova učestalost zavisi od farmakoloških karakteristika leka, metodologije istraživanja neželjenih efekata lekova i načina njihovog registrovanja. Pored ostalog, lekovi izazivaju različite tipove anemija. Neke od njih mogu da se izbegnu ili ublaže detaljnim uzimanjem od bolesnika farmakološke anamneze, koja podrazumeva ne samo dobijanje podataka o nazivu leka, već i o njegovoj dozi, načinu i dužini primene, kao i o drugim karakteristikama koje su od značaja za ispoljavanje efekata lekova.

AB  - Controversy about proconvulsant and anticonvulsant nitric oxide (NO) effects and the place of oxidative stress in convulsions, are still a matter of research. We investigated the interaction between 2-amino-5-phosphonovaleric acid (APV), a competitive N-methyl-D-aspartate (NMDA) receptor antagonist and Nw-nitro-L-arginine methyl ester (L-NAME), a nonselective nitric oxide synthase (NOS) antagonist, in pentylenetetrazole (PTZ)-induced convulsions. Pentylenetetrazole was applied to adult Wistar rats intraperitoneally (ip) in a single dose of 80 mg/kg, and L-NAME (10 µg/10 µl) or APV (20 µg/10 µl) intracerebroventricularly (icv), 30 and 10 minutes before PTZ, respectively. In the same manner, another group received both antagonists. Control animals were given 0.9% saline. Nw-nitro-L-arginine methyl ester exerted a weak anticonvulsant effect, preventing generalized clonic (GCC) and clonic-tonic convulsions (CTC) in 17% of cases. With APV protection against GCC and CTC was 100%, forelimb dystonia (FLD) was decreased in 33% of cases, and time to onset of all convulsive patterns was prolonged (p<0.05 to 0.01). All effects of APV, except in CTC, were reversed by L-NAME applied prior to APV. In APV-PTZ treated animals, superoxide anion content was increased in the forebrain cortex, striatum and hippocampus, without an overwhelmed antioxidative superoxide dismutase (SOD) defense system in the other treatments. When the APV-PTZ group was treated with L-NAME, both SOD activity and superoxide anion content were additionally decreased indicating that the NOS-NO system was involved in the metabolism of superoxide anions. It is suggested that clinical and biochemical effects of NO strongly depend upon the pretreatment and might lead to a wrong impression of NO contradictory activity.
AB  - Kontroverzni nalazi o prokonvulzivnim kao i antikonvulzivnim efektima azot oksida (NO) i značaju oksidativnog stresa u konvulzijama, i dalje su predmet istraživanja. U konvulzijama izazvanim primenom pentilentetrazola (PTZ) ispitivali smo interakciju između 2-amino-5-fosfovalerinske kiseline (APV) kompetitivnog antagoniste N-metil-D-aspartat (NMDA) receptora i Nw-nitro-L-arginin metil estra (L-NAME), neselektivnog antagoniste azot oksid sintaze (NOS). Odraslim pacovima Wistar soja, PTZ je ubrizgavan intraperitonealno (ip) u jednoj dozi od 80 mg/kg. Ostale supstance, L-NAME (10 µg/10 µl) i APV (20 µg/10 µl), primenjivale su se intracerebroventrikularno (icv), i to L-NAME 30, a APV 10 minuta pre PTZ. Po istom vremenskom principu, jedna grupa dobila je oba antagonista, a kontrolna fiziološki rastvor NaCl. Nw-nitro-L-arginin metil estar ispoljio je slabo antikonvulzivno dejstvo, smanjujući incidenciju generalizovanih kloničnih (GCC) i klonično-toničnih konvulzija (CTC) za 17%. Za razliku od L-NAME, APV je sprečila nastanak GCC i CTC kod svih životinja (100%), a incidencija klonusa prednjih nogu (FLD) smanjena je za 33%. Istovremeno primenom APV produženo je vreme od aplikacije PTZ do pojave svih konvulzivnih tipova (p<.05 do 0.01). Primenom L-NAME pre APV, umanjeni su efekti APV, pri čemu je došlo do povećanja incidencije FLD i GCC za 16% odnosno 50%. U kori prednjeg mozga, strijatumu i hipokampusu, životinja koje su dobile APV+PTZ, došlo do povećanja koncentracije superoksidnog anjona. Aktivnost superoksid dizmutaze ne prati ovaj skok. Njen dodatni pad u grupi tretiranoj sa L-NAME pre APV+PTZ, ukazuje da je sistem NOS-NO uključen u metabolizam superoksidnog anjona. Dobijeni rezultati ukazuju da klinički i biohemijski efekti NO u velikoj meri zavise od prethodno primenjenih supstanci i promena izazvanih njima, što može da doprinose sticanju pogrešnog utiska o kontradiktornim dejstvima NO.

AB  - Quinolinic acid (QA) produces a pattern of selective cell loss in the striatum, that closely mimics that of Huntington's disease (HD). The aim of this study was to investigate the antioxidative status in the thalamus after intrastriatal application of QA and the influence of nerve growth factor (NGF) on such neurotoxicity. Wistar rats were treated intrastriatally (coordinates: 8.4A, 2.6L, 4.8V), using a stereotaxic instrument. The first group was treated with QA (150 nmol/l). The second group was treated with QA, followed by NGF (4.5 mg/kg b.w). The control group was treated with 0.9 % saline solution. Seven days after the treatment, we found decreased superoxide dismutase (SOD) activity in mitochondrial fractions of the striatum of both groups. In the thalamus, SOD activity showed no differences. The content of superoxide anion increased in the striatum of QA- treated animals. It was decreased in both structures in the group that was treated with QA and NGF. In the QA+ NGF-treated group, we found increased glutathione peroxidase (GSHPx) and GSH, compared to the group that was treated with QA only, but these values were lower than in the controls. Thus, NGF showed beneficial effects on the oxido-reduction status in the striatum, and also in the thalamus, a structure that is separated from but tightly connected with the striatum.
AB  - Hinolinska kiselina (HK) prouzrokuje takav selektivni gubitak ćelija u strijatumu, koji veoma dobro imitira onaj kod Huntingtonove bolesti. Cilj ovog istraživanja bio je da se ispita antioksidativni status u talamusu nakon aplikacije HK u strijatum i uticaj NGF na takvu neurotoksičnost. Wistar pacovi su tretirani intrastrijatno, pomoću stereotaksičnog instrumenta (koordinate: 8,4A, 2,6L, 4,8V). Prva grupa je bila tretirana HK (150 nmol/l). Druga grupa je bila tretirana HK, a nakon toga je dobila NGF (4.5 mg/ kg b.w). Kontrolna grupa je bila tretirana fiziološkim rastvorom. Sedam dana nakon tretmana, u mitohondrijskim frakcijama strijatuma, našli smo smanjenu aktivnost SOD u obema grupama. U talamusu, aktivnost SOD se nije promenila. Sadržaj superoksidnog anjona se povećao u strijatumu životinja koje su bile tretirane HK, a smanjio se u obema strukturama, u grupi koja je bila tretirana sa HK i NGF. U HK+ NGF-tretiranoj grupi, našli smo povećanu aktivnost GSHPx i GSH u odnosu na grupu koja je bila tretirana samo sa HK, ali su te vrednosti bile manje u odnosu na kontrolne. NGF je pokazao povoljne efekte na oksido-reduktivni status u strijatumu, ali takođe i u talamusu, strukturi koja je odvojena, ali veoma blisko povezana sa strijatumom.
