Magdelainella bozidarcurcici n. Sp. (Coleoptera, Cholevidae): A new endemic beetle from southwest Serbia
Authors: Curcic Srecko , Brajkovic Miloje
Published: February 2009

A new species of hypogean beetles, Magdelainella bozidarcurcici n. sp (Cholevidae, Bathysciinae), is described from the Pecina u Potkapilijama Cave, village Trudovo, nr. Nova Varos, southwest Serbia. From its closest congeners (M winkleri Jeannel, M. hussoni Jeannel and M. serbica M?ller) this new form is clearly distinct in many important respects such as: body size, length to breadth ratios of some antennomerae, shape of pronotum and elytra, form of mesosternal carina, form of aedeagus, shape of paramerac and specific setation, and the peculiar form of the structures forming the inner sac. Additionally, this new species has been illustrated, described and thoroughly diagnostified. It is apparent that M. bozidarcurcici belongs to an old phyletic lineage of the Tertiary origin, which is relic and endemic both to southwest Serbia and the Balkan Peninsula.

Distribution of blue-green algae (Cyanophyta) in streams of Mt. Stara planina: Serbia
Authors: Simic Snezana
Published: February 2009

Distribution of blue-green algae was studied at 14 sites along five streams in the Stara Planina mountains. Algological samples were taken from the community of benthos and periphyton in the spring (March-May 1991), summer (June-August 1991, August 1996, July 1997), and autumn (September-November 1991, September 1997). Algae of the classes Chamaesiphonophyceae (species of the genus Chamaesiphon) and Hormogoniophyceae (species of the genera Symploca, Phormidium, Oscillatoria, Schizothrix, Nostoc, Rivularia Homoeothrix, Tolypothrix, and Plectonema) were recorded. The species Chamaesiphon cylindricus, Symploca radians, Phormidium coutinhoi, Nostoc coeruleum, Homoeothrix janthina, Plectonema thomasinianum, and Tolypothrix distorta were registered herein first time in Serbia. Occurrence of blue-green algae in highland brooks and rivers of the Stara Planina mountains was monitored in relation to a large number of abiotic factors e.g. altitude above level, stream dimensions (width and depth), substrate bottom type (%), current flow rate, water temperature and pH oxygen concentration, concentrations of nitrates and phosphates, and BOD5, using Principal Coordinates analysis (PCX)).
Rat liver tyrosine aminotransferase activity and induction by dexamethasone upon cadmium intoxication
Authors: Dundjerski Jadranka , Predic Jelena , Cvoro Aleksandra , Matic Gordana
Published: February 2009

This study was focused on Cd effects on basal and dexamethasone-induced tyrosine aminotransferase (TAT) activity in the rat liver cytosol. Cadmium (Cd), applied in the dose of 2 mg/kg b.w., stimulated both TAT activity and its induction by dexamethasone, inducing the most prominent alterations 24 h after administration. Doses lower than 2 mg Cd/kg b.w. were ineffective while the higher ones (3 and 4 mg Cd/kg b.w) led to the changes similar to those reached by 2 mg Cd/kg. The in vitro application of different Cd concentrations to the liver cytosol rendered the enzyme activity unchanged suggesting that the metal acted at the level of TAT gene transcription.

Authors: Curcic Srecko , Brajkovic Miloje , Curcic Bozidar , Mitic Bojan
Published: February 2009

A new genus and species of cave ground beetles (Javorella javorensis n. gen. n. sp) has been described from the Pecina pod Kapilijama Cave, village Trudovo, nr. Nova Varos, southwestern Serbia. This new genus is clearly distinct from all other genera in many important respects such as: the presence of unfunctional flattened reduced eyes, the presence of 10-14 depigmented ommatidia, the presence of a pigmented oval eye border, the presence of deep and complete frontal furrows (but shallow and less visible in their posterior thirds), the presence of completely smooth cheeks, the presence of distinct furrows on fore tibias along their length, the ratio of the length/breadth of the first article of protarsomere in male; the presence of 2 elytral discal setae, the specific position of humeral setae and the unique shape of the copulatory piece. This new genus comprises also an additional species, J. suvoborensis (Pavicevic and Popovic), described elsewhere from the Pecina u Brezacima Cave, village Brezaci, Rajac, Mt. Suvobor, near Valjevo, western Serbia. The two species clearly differ in many important respects; the new genus and its members belong to an old and separate phyletic lineage, distinct from all other existing species groups. Additionally, these forms are relic and endemic to Serbian caves.

Published: February 2009

Melliferous plant species in the forests near Blace (South Serbia) were investigated in order to estimate the significance, contribution, quality and ecological characteristics of representatives of the apiflora as potential nectar and pollen sources, the elements of bee pasturage. The significance of melliferous plants was determined on the basis of nectar and pollen production intensity, as well as by following blooming periods. According to adaptations to moisture, light, and temperature, melliferous species can be relegated to eight groups and six subgroups. Out of the total number of melliferous species in the investigated area (223), the forest apiflora accounted for 82 species (36,77%). The species with highest nectar and/or pollen production are: Alnus glutinosa, Corylus avellana, Paulownia tomentosa, Picea abies, Prunus tenella, Robinia pseudoacacia, species of the genera Salix, Tilia, and Campanula, Atropa bella-donna, Calamintha officinalis, Glechoma hederacea, Pulmonaria officinalis, Salvia glutinosa and Valeriana officinalis.

Authors: Nikolic Z. , Brajkovic Miloje
Published: February 2009

In a phytocenosis of sessile oak and hornbeam with butcher?s broom (Querco-Carpinetum serbicum aculeatetosum Jovanovic 1951) on the territory of Mt. Avala, 42 species of sawflies belonging to the families Argidae Pamphiliidae and Tenthredinidae have been registered. The 42 species that were found, as many as 19 (or 45.23%) are new for the entomofauna of Serbia and Montenegro. Of these 19 species, one belongs to a genus newly recorded on our territory (the genus Cephaleia). The dominant family is the family Tenthredinidae, to which 38 of the registered species belong. The family Tenthredinidae is also dominant in this community with respect to the number of specimens caught, as only a few specimens of species of the other two families were present. The subfamily Tenthredininae is the most numerous subfamily of the family Tenthredinidae inasmuch as 19 of its species were registered in the course of two-year sampling. The most abundant species in the observed phytocenosis are species of the genus Macrophya, while the majority of species of sawflies during the research were present in the field in only small numbers.

The effect of plant growth regulators on centaury (Centaurium erythraea Rafn) seeds germination
Authors: Mijajlovic Nada , Grubisic Dragoljub , Giba Zlatko , Konjevic Radomir
Published: February 2009

Centaury seeds are light-requiring. Long-term red light irradiation caused more than 80% of seeds to germinate. Seeds did not germinate in darkness. Gibberellic acid and GA7 can replace light, but N-substituted phtalimide AC 94,377 was ineffective. Light-induced germination was inhibited by abscisic acid and growth retardants such as ancymidol, tetcyclacis, and paclobutrazole. Growth retardant-caused inhibition can be overcome by the addition of gibberellic acid.

Authors: Vukicevic-Radic Olivera , Jovanovic Tatjana , Matic Rada , Kataranovski Dragan
Published: February 2009

The age structure of yellow-necked mouse (Apodemus flavicollis Melchior 1834) has been analyzed in individuals obtained by two methods: Trapping with Sherman live traps and obtainment of skulls from long-eared owl (Asio otus Linnaeus, 1758) pellets (predator diet analysis). One hundred and forty-four mice were analyzed for the degree of wear of the surface of molar crowns, and an additional 74 measurements were performed on captive-born Apodemus flavicollis individuals. We used a refined model of comparison that included seven classes of mouse age, rather than four classes, as suggested by other authors.

Authors: Paunovic Momir , Simic Vladica , Jakovcev-Todorovic Dunja , Stojanovic Bojana
Published: February 2009

The present work cites results of investigating aquatic macroinvertebrates of the Danube River on the sector upstream from the Iron Gate (KM 1083-1071). The investigated part is interesting from the hydrobiological standpoint above all due to differences of faunal composition in relation to higher sections that could be expected in view of differences in overall characteristics of the river. A rich macroinvertebrate community (84 taxa) was observed. The diversity of taxa is primarily a result of habitat diversity within the given stretch. Oligochaeta and Mollusca were the principal components.

Authors: Mrdakovic Marija , Ilijin Larisa , Jankovic-Tomanic Milena , Vlahovic Milena , Prolic Zlatko , Peric-Mataruga Vesna , Lazarevic Jelica , Nenadovic Vera
Published: February 2009

The effects of different temperatures (23?C and 8?C) on activity of corpora allata (CA) and dorsolateral (L1, L2) protocerebral neurosecretory neurons were investigated in Morimus funereus Mulsant (1863) larvae collected from a natural population during March. Activity of CA was revealed by monitoring of CA volume and cell number. Increase of CA volume after two day exposure to both temperatures was shown to be the result of increase in cell number. Activity of CA was higher at 23?C than 8?C. Activity of L1 and L2 neurosecretory neurons was inhibited at both temperatures. Neurosecretory neurons were more sensitive to temperature of 23?C than 8?C. It can be supposed that dorsolateral neurosecretory neurons synthesize neurohormones that affect CA activity, depending on environmental temperature.

Authors: Zivic Ivana , Markovic Z. , Ilic Jelena
Published: February 2009

We investigated macroozobenthos communities in the Temska and Visocica Rivers at 10 localities during the summer and autumn of 2001. In 46 samplings of quantitative and 10 of qualitative analysis, 101 taxa from 17 groups of macrozoobenthos are identified. The most diverse group is the order Trichophtera (28 species from nine families). Less diverse with (only one species) are Nematomorpha, Hirudinea, Odonata, and Megaloptera. At all of the chosen localities, the most common species are Elmis aenea (70.00%), Ancylus fluviatilis, and Baetis sp. (60.00%). All those localities on the Visocica and Temska Rivers are very similar. The index of similarity varies from 12.5% (between Vi0 and Te0) to 70.7% (between Te1 and Te2). In the Temska River the Shannon-Weaver diversity index varies from 1.80 (at Te3) to 2.45 (at Te0). In the Visocica River, the highest diversity of macrozoobenthos is at the Vi3 locality (2.59), the lowest at Vi0 (1.40). Less diverse macrozoobenthos communities are found at the Vi0 and Te3 localities. At the same time, these localities have the highest values of Simpson's index (0.35 and 0.34, respectively).

Up to 1995, the total number of earthworm taxa in Sumadija was 37. After our present study this number has risen to 43 taxa. As for the zoogeographical position of the earthworms of Sumadija, the established taxa have the following types of distribution: European (11 taxa), cosmopolitan (10), Holarctic (eight) Palearctic (two), South European (five), Balkan (three) and endemic (four).
Distribution of two species of the earthworms fauna of Sumadija (Serbia) in the Balkans and neighboring territories
Authors: Stojanovic Mirjana , Karaman Spasenija
Published: February 2009

The authors discuss the zoogeographic distribution in the Balkans of two species of the earthworm fauna of Sumadija, namely Aporrectodea sineporis (Omodeo, 1952) and Helodrilus cernosvitovianus (Zicsi, 1967). Aporrectodea sineporis has been recognized in the central and eastern parts of Serbia Helodrilus cernosvitovianus only on the territory of Mt. Bukulja (in the central part of the country). These are new findings for the earthworm fauna of Sumadija. The available evidence indicates that H. cernosvitovianus is mainly a Balkan element, while A. sineporis has a distribution of the South European type.

Assessment of age and intersexual size differences in Bufo bufo
Authors: Cvetkovic Dragana , Tomasevic Natasa , Aleksic Ivan , Crnobrnja-Isailovic Jelka
Published: February 2009

Numerous studies have underlined the complex nature of relationship between age, size, and reproductive traits in anurans. One of the most intriguing problems for evolutionary biologists is intersexual difference in body size (SSD). For testing various hypotheses about SSD, we need reliable estimates of its extent (the important issue being the choice of trait for analysis) as well as the accurate determination of individual age. The measures of SSD may be subject to error if estimated from populations with unknown age distribution; amphibians continue to grow throughout their life and SSD is linked to sex differences in traits such as age at maturity and lifespan. In the present paper, we analyze problems involved in accurate determination of age structure and factors that may lead to under- or overestimation of individual age, as well as the problem of appropriate choice of traits, in the light of our experience and results of investigating populations of common toad (Bufo bufo) in the vicinity of Belgrade.
Modification of the acetylcholine-induced current of the snail Helix pomatia L. by fast temperature changes
Authors: Nedeljkovic M. , Kartelija Gordana , Radenovic Lidija
Published: February 2009

Using the single electrode voltage clamp method, we found that acetylcholine (aCh) induces transient inward dose-dependent current on the membrane of the identified Helix pomatia Br neuron. We analyzed the effects of fast cooling and heating as well as thermal acclimation on the aCh inward current. the experiments were conducted on active and dormant snails acclimated to either 20 or 7?C for at least four weeks. the Hill coefficient remained approximately 1 in all cases, which means that there is a single aCh binding site on the membrane. Fast temperature alternations induce binding affinity changes. in the work presented, we analyzed the effects of cooling on the aCh-induced inward current. the amplitude of aCh-induced inward current was markedly reduced after cooling, and the speed of decay of the aCh response was lower.

Authors: Rajkovic Dragana , Jurisic A.D.
Published: February 2009

As specific arthropods, ticks in urban environments transmit the agents of dangerous contagious diseases endangering human and animal health. They are vectors of numerous infective agents that cause serious diseases of animals such as babesiosis and ehrlichiosis. Tick populations maintain and transmit an increas?ing number of different infective agents. In regard to the human population, they transmit the agents of tick encephalitis, Omsk hemorrhagic disease, Crim-Congo hemorrhagic disease, Kyasa-nur forest fever, ixodid fever, Q fever, Rocky Mountain spotted fever, tularemia, Siberian tick typhus and Lyme disease the last of which according to acarological references has become the dominant zoonosis in over 140 of the world's countries. In urban environments ticks represent problem both for their epidemiological significance and as organisms whose presence disturbs people during their work and rest. In Europe, the two most fre?quent species and Ixodes ricinus and Ixodes persulcatus. Both species have a wide spectrum of hosts.
Contribution to the myrmecofauna (Formicidae, Hymenoptera) of Mt. Kopaonik (Serbia)
Authors: Petrov Ivan
Published: February 2009

The myrmecofauna of Serbia is still insufficiently investigated. In the past ants were not a challenge for the entomologists of Serbia, only a few of which paid attention to ants and registered some ant species among other insect species. Zivojinovic (1950) registered 18 species of ants in the forest region of Majdanpek (Serbia), although he considered some valid species (Lasius alienus, L. brunneus, Camponotus herculeanus, and Formica pratensis) as subspecies. Vogrin (1955) elaborated Hymenoptera Aculeata of Yugoslavia, and registered 16 species of ants in Serbia (Srem). Gradojevic (1963) listed 11 species of ants of Deliblatska Pescara (Deliblato Sands) (Vojvodina, Serbia).

Published: February 2009

In vitro culture of the moss Amblystegium serpens (Amblystegiaceae) was established on hormone-free Murashige and Skoog (MS) medium that contained a half amount of MS micro- and macro- mineral salts and vitamins, 100 mg/l myoinositol, 30 g/l sucrose, and 0.70% (w/v) agar. Spores were germinated and primary protonema developed on the above medium at 16 h day/8 h night 25?2?C, 60-70% air humidity, and irradiance of 47 ?mol/m2s. Three months after development of primary protonema, seven sporophytes appeared directly from primary protonema without generation alternation. The phenomenon of apogamous sporophyte formation is very rare, both in nature and under in vitro conditions. This is the first report of apogamy induced by Amblystegium serpens.
Chlorophyll and carotenoid content in wheat cultivars as a function of mineral nutrition
Authors: Bojovic Biljana , Stojanovic J.
Published: February 2009

Determination of chlorophyll content as an indirect method of estimating the productivity of vegetation represents a good way to gain an understanding of the photosynthetic regime of plants. Physiological investigations of chlorophyll and carotenoid content in the uppermost internode of several wheat cultivars were carried out at the outset of the flowering phase. The dependence of chlorophyll and carotenoid content on the fertilization variant was established at that time. The tested wheat cultivars were grown under conditions of five fertilization variants. The content of chlorophyll a, chlorophyll b, and total chlorophyll (Chl a+b) was measured and carotenoid content was determined on each variant. The results indicate that chlorophyll and carotenoid content depended on the presence and ratio of mineral elements in the substrate. This is demonstrated by the variant with unfertilized soil, where chlorophyll and carotenoid content in all cultivars was lowest. The variant of fertilization with N and P turned out to be most favorable. The next most favorable variant was the one with nitrogen alone, and it was followed by the variant with N and K.

Species composition, spatial distribution and temporal occurrence of mayflies (Ephemeroptera) in the Vlasina river (southeast Serbia)
Authors: Paunovic M. , Jakovcev-Todorovic Dunja , Simic V. , Stojanovic Bojana , Veljkovic Ana
Published: February 2009

The mayfly (Ephemeroptera) fauna was studied during investigations of the Vlasina River (Serbia) conducted in 1996. Twenty-six species from 14 genera belonging to eight families were recorded. Compared to similar aquatic ecosystems in Serbia and Europe, the ephemeropteran fauna of the Vlasina River is characterized by high species diversity. Good water quality and habitat heterogeneity led to the observed richness of taxa. Based on fauna distribution, the middle reach of the river can be divided into three different segments - upper, middle, and lower. Distribution of the two dominant families, Heptageniidae and Baetidae, is emphasized. Representatives of Baetidae reach their highest density in July, while Heptageniidae were the most abundant in November. The recorded mayflies represent widely distributed European or Holarctic species.

Authors: Demajo M. , Jozanov-Stankov Olga , Djujic Ivana
Published: February 2009

The mammalian pineal gland regulates a number of important physiological processes. In this paper we report changes in the content of iron (Fe), zinc (Zn), copper (Cu), and selenium (Se) in the male rat pineal glands at 4, 5, 8, and 12 months of age. The effect of Se supplementation in drinking water on the content of pineal gland microelements was also studied. Selenium (Se)-dependent changes in pineal gland reported in this study suggest novel physicochemical and biochemical properties of Se, an important element essential in the antioxidative processes, yet known to influence a number of endocrine processes.

Authors: Paunovic M. , Jakovcev-Todorovic Dunja , Simic V. , Stojanovic Bojana , Petrovic Ana
Published: February 2009

The aim of the study presented was to define trophic relationships within the benthic community according to functional feeding groups (FFG) in the Vlasina River (Southeast Serbia), with an attempt to use those results to describe the watercourse. In an investigation performed during 1996, a total of 125 macrozoobenthic taxa were identified, 95 of which were included in FFG analyses. Although the investigated part of the river, in its physical and chemical characteristics, as well as characteristics of the benthofauna, generally corresponds to what could be expected, certain variations of faunal composition were observed along the river. Two groups of sites were separated by FFG analysis - sites on the upper section of the river and on a tributary (the Gradska River) comprised one group, while the remaining sites made up the other.

Published: February 2009

Results of investigating the community of aquatic invertebrates in the Ribnica and Lepenica Rivers (Kolubara River drainage area) are given in the present work. Forty-three taxa are recorded. In relation to other studied streams in Serbia, the investigated rivers are characterized by high diversity of macroinvertebrates. Cluster analysis indicates that the locality on the Lepenica stands apart from those on the Ribnica, which is a consequence of the difference of habitats found at them. Results of saprobiological analysis of the macrozoobenthos in the given rivers indicate that their waters belong to quality classes I and II.

Published: February 2009

Changes in ascorbic acid (AA) concentration were examined in the adrenals, serum and liver of Wistar rats exposed to cold (6 ?C) and heat stress (38 ?C) for 60 min. The exposure of animals to cold stress for 60 min did not change concentration of AA in the serum, adrenals and liver as compared to controls maintained at room temperature. After a 60 min heat exposure the concentration of AA in the adrenals decreased (***p<0.001), in the liver remained unchanged whereas it significantly increased in the serum (***p<0.001) in respect to control values. .

Published: February 2009

The ACE and MMP-3 loci are involved in the vascular remodeling, increased intima media thickness and arterial stiffness associated with hypertension. We determined ACE I/D and MMP-3 5A/6A gene polymorphisms in 231 Caucasian males (126/105, hypertensive/normotensive). Owing to age-related differences hypertension, the sample was truncated with respect to age (the cut-off point was the age of 40). Our results indicate that ACE I/D and MMP-3 5A/6A polymorphisms are likely to be risk factors for hypertension in men from Serbia = 40 years of age. In the same group, the combined effect of DD/6A+ genotypes on hypertension was more pronounced than their separate effect. .

Authors: Bogdanovic Jelena , Prodanovic R. , Milosavic N. , Prodanovic Olivera , Radotic Ksenija
Published: February 2009

Activity and isoenzyme composition of superoxide dismutase in the apoplast and whole-needle extract of Picea omorika (Panc.) Purkyn?, was studied. Total SOD activity of the soluble fraction of the needle extract exceeded markedly that of the apoplastic SOD. Several acidic and two slow-migrating basic isoforms were found in the whole extract. Extracellular SOD had an extremely acidic isoform. Using specific inhibitors, we identified Cu/Zn- and MnSOD forms in the total extract, but only MnSOD in the apoplast. The Feisoform was not present in a detectable amount.
Do B chromosomes affect fecundity in yellow-necked mice Apodemus flavicollis (Rodentia, Mammalia)?
Authors: Blagojevic Jelena , Jojic Vida , Bugarski-Stanojevic Vanja , Adnadjevic Tanja , Vujosevic M.
Published: February 2009

The effects of the presence of B chromosomes on fecundity of the yellow-necked mouse Apodemus flavicollis were studied in 46 females without and 28 with Bs from four localities in Serbia. Uterine inspection showed that there was no significant difference in the mean number of scars and embryos between females with and those without Bs. Thus, B chromosomes do not appear to affect the fecundity of females carrying them, indicating that the presence of Bs does not affect fitness characteristics.
Cases of spontaneous interbreeding of wolf and domestic dog in the region of Southeast Banat
Authors: Milenkovic M. , Habijan-Mikes Vesna , Matic Rada
Published: February 2009

The study presents the first documented data indicating the occurrence of spontaneous interbreeding of wolf and domestic dog in nature on the territory of Serbia, based on three specimens originating from the region of Southeast Banat. Some unique morpho-anatomical malformations of the cranium in two specimens are described. Based on complex morphological and craniometrical analysis of hybrid specimens and comparison with the corresponding material of authentic wolves from this region, it is possible to follow a local process of multiple wolf/dog hybridization and disturbance of the authentic genetic structure of wolf. The identification of wolf/dog hybrids is a subject of primary concern for the development of conservation and management strategies. Because of great vulnerability of the population of South-Carpathian wolves on the boundaries of their range in Serbia, there is a need for permanent and increased protection in order to maintain their adequately strong population in this region. .

Published: February 2009

Research was conducted to determine whether Phyllocnistis citrella Stainton (Lepidoptera, Gracillariidae) has any preference in attacking either the upper or the lower surface of the leaves of citrus trees. This investigation took place during the year 1999 at Marathon (Attica, Central Greece) while studying the dispersal of P. citrella on the leaves of three different types of citrus trees. Data on the overwintering and parasitism of P. citrella from different areas in Greece are also presented during the years 1999-2002. In addition, the effect of P. citrella infestation on imidacloprid-treated and untreated tangerine trees was comparatively studied. The parasitoids collected were Pnigalio sp. (Hymenoptera, Eulophidae), Cirrospilus sp. (Hymenoptera, Eulophidae), Neochrysocharis formosa (Westwood) (Hymenoptera, Eulophidae) and Citrostichus phyllocnistoides (Narayanan) (Hym., Eulophidae).
Monitoring water quality using zooplankton organisms as bioindicators at the Dubica fish farm, Serbia
Authors: Dulic Zorka , Mitrovic-Tutundzic Vera , Markovic Z. , Zivic Ivana
Published: February 2009

The quality of water at the Dubica Fish Farm was evaluated by the saprobiological method using the Pantle-Buck saprobity index, during one carp production cycle in the year 2000. By qualitative and quantitative analysis of the zooplankton community, bioindicator species were selected for evaluation of water quality. During the whole period of research, the saprobity index indicated class II water quality, which is suitable for rearing carp in a semi-intensive system as far as natural food is concerned. There was a general trend of decrease in the saprobity index from the beginning to end of the season, its values ranging from 2.05 do 1.77, and a gradual improvement of water quality towards the end of the season. This is partly a result of natural processes (terminated degradation of introduced organic matter as well as settlement of suspended matter introduced with the supply water) and partly a consequence of the application of ichthyological, agrotechnical, and hydrotechnical measures. .
Effect of glutamate antagonists on nitric oxide production in rat brain following intrahippocampal injection
Authors: Radenovic Lidija , Selakovic Vesna , Janac Branka , Todorovic Dajana
Published: February 2009

Stimulation of glutamate receptors induces neuronal nitric oxide (NO) release, which in turn modulates glutamate transmission. The involvement of ionotropic glutamate NMDA and AMPA/kainate receptors in induction of NO production in the rat brain was examined after injection of kainate, a non-NMDA receptor agonist; kainate plus 6-cyano- 7-nitroquinoxaline-2,3-dione (CNQX), a selective AMPA/kainate receptor antagonist; or kainate plus 2-amino-5-phosphonopentanoic acid (APV), a selective NMDA receptor antagonist. Competitive glutamate receptor antagonists were injected with kainate unilaterally into the CA3 region of the rat hippocampus. The accumulation of nitrite, the stable metabolite of NO, was measured by the Griess reaction at different times (5 min, 15 min, 2 h, 48 h, and 7 days) in hippocampus, forebrain cortex, striatum, and cerebellum homogenates. The used glutamate antagonists APV and CNQX both provided sufficient neuroprotection in the sense of reducing nitrite concentrations, but with different mechanisms and time dynamics. Our findings suggest that NMDA and AMPA/kainate receptors are differentially involved in nitric oxide production.
