AB  - Introduction/Aim. In acute organophosphate poisoning the issue of special concern is the appearance of muscle fasciculations and convulsions that cannot be adequately antagonised by the use of atropine and oxime therapy. The aim of this study was to examine atidotal effect of obidoxime or HI-6 combinations with memantine in mice poisoned with soman, dichlorvos or heptenophos. Methods. Male Albino mice were pretreated intravenously (iv) with increasing doses of oximes and/or memantine (10 mg/kg) at various times before poisoning with 1.3 LD-50 of soman, dichlorvos or heptenophos, in order to determine the median effective dose and the efficacy half-time. In a separate experiment, cerebral extravasation of Evans blue dye (40 mg/kg iv) was examined after application of memantine (10 mg/kg iv), midazolam (2.5 mg/kg intraperitonealy - ip) and ketamine (20 mg/kg ip) 5 minutes before soman (1 LD-50 subcutaneously - sc). Results. Coadministration of memantine induced a significant decrease in median effective dose in null time of both HI-6 (7.96 vs 1.79 mmoL/kg in soman poisoning) and obidoxime (16.80 vs 2.75 mmoL/kg in dichlorvos poisoning; 21.56 vs 6.63 mmoL/kg in heptenophos poisoning). Memantine and midazolam succeeded to counteract the soman-induced proconvulsive activity. Conclusion. Memantine potentiated the antidotal effect of HI-6 against a lethal dose of soman, as well as the ability of obidoxime to antagonize the toxic effects of dichlorvos and heptenophos probably partly due to its anticonvulsive properties.
AB  - Uvod/Cilj. Poseban problem pri trovanju organofosfornim jedinjenjima predstavljaju mišićne fascikulacije i konvulzije, koje se ne mogu u potpunosti antagonizovati primenom atropina i oksima. Cilj ovog rada bio je ispitivanje antidotskog efekta kombinacije memantina i oksima HI-6 kod trovanja somanom, kao i kombinacije memantina sa obidoksimom kod trovanja dihlorvosom i heptenofosom. Metode. Albino miševima, mužjacima, u repnu venu date su rastuće doze oksima i/ili memantina (10 mg/kg) u različitim vremenskim intervalima pre intravenskog (iv) davanja 1,3 LD-50 somana, dihlorvosa ili heptenofosa. Praćenjem stepena preživljanja, izračunate su srednje efektivne doze i poluvreme efikasnosti. U odvojenom eksperimentu praćena je cerebralna ekstravazacija boje Evans plavo (40 mg/kg iv) nakon primene memantina (10 mg/kg iv), midazolama (2,5 mg/kg intraoperitonealno - ip) i ketamina (20 mg/kg ip) 5 min pre davanja somana (1 LD-50 supkutano - sc). Rezultati. Primenom kombinacija sa memantinom srednje efektivne doze u nultom vremenu i HI-6 (7,96 vs 1,79 mmoL/kg kod trovanja somanom) i obidoksima (16,80 vs 2,75 mmoL/kg kod trovanja dihlorvosom; 21,56 vs 6,63 mmoL/kg kod trovanja heptenofosom) bile su višestruko niže u odnosu na dozu samog oksima. Memantin i midazolam uspešno su suprimirali prokonvulzivni efekat somana. Zaključak. Rezultati ove studije pokazuju da primena memantina u kombinaciji sa oksimima obezbeđuje bolji zaštitni efekat nego sam oksim, a u osnovi ovog efekta verovatno leži i njegov antikonvulzivni potencijal.

AB  - Classical benzodiazepines (BZs) exert anxiolytic, sedative, hypnotic, muscle relaxant, anticonvulsive, and amnesic effects through potentiation of neurotransmission at GABA(A) receptors containing alpha(1), alpha(2), alpha(3) or alpha(5) subunits. Genetic studies suggest that modulation at the alpha(1) subunit contributes to much of the adverse effects of BZs, most notably sedation, ataxia, and amnesia. Hence, BZ site ligands functionally inactive at GABAA receptors containing the alpha(1) subunit are considered to be promising leads for novel, anxioselective anxiolytics devoid of sedative properties. In pursuing this approach, we used two-electrode voltage clamp experiments in Xenopus oocytes expressing recombinant GABAA receptor subtypes to investigate functional selectivity of three newly synthesized BZ site ligands and also compared their in vivo behavioral profiles. The compounds were functionally selective for alpha(2)-, alpha(3)-, and alpha(5)-containing subtypes of GABA(A) receptors (SH-053-S-CH3 and SH-053-S-CH3-2'F) or essentially selective for alpha(5) subtypes (SH-053-R-CH3). Possible influences on behavioral measures were tested in the elevated plus maze, spontaneous locomotor activity, and rotarod test, which are considered primarily predictive of the anxiolytic, sedative, and ataxic influence of BZs, respectively. The results confirmed the substantially diminished ataxic potential of BZ site agonists devoid of alpha(1) subunit-mediated effects, with preserved anti-anxiety effects at 30 mg/kg of SH-053-S-CH3 and SH-053-S-CH3-2'F. However, all three ligands, dosed at 30 mg/kg, decreased spontaneous locomotor activity, suggesting that sedation may be partly dependent on activity mediated by alpha(5)-containing GABAA receptors. Hence, it could be of importance to avoid substantial agonist activity at alpha(5) receptors by candidate anxioselective anxiolytics, if clinical sedation is to be avoided.

AB  - Benzodiazepine site inverse agonists may increase or decrease locomotor activity in rodents, depending on the experimental settings. We have compared the behavioral responses to environmental novelty of rats treated with the non-selective inverse agonist DMCM (2 mg/kg) and the alpha(1)-subunit affinity-selective inverse agonist 3-EBC (15 mg/kg). The behavior in spontaneous locomotor assay (during 45 min) and elevated plus maze (EPM) was automatically recorded. In the EPM, general activity-related parameters were similarly decreased, whereas only DMCM inhibited open-arm activity. In the locomotor assay, both compounds depressed locomotion in the first 15 min and activity in the central zone of the chamber. However, the influence of 3-EBC was less pronounced. The alpha(1)-subunit selective antagonist beta-CCt (15 mg/kg) attenuated locomotor depression, but not the central-zone avoidance elicited by DMCM. When habituated to the chamber, DMCM-treated animals emitted a plateau phase of activity, which disappeared by adding beta-CCt. Hence, inhibition of activity in exposed areas may be mediated by non-alpha(1)-subunits, whereas both alpha(1) and non-alpha(1)-subunits may participate in suppression of activity in more protective areas of an apparatus. Hyperlocomotion in habituated animals may depend primarily on the alpha(1)-subunit. Moreover, the bimodal influence of inverse agonists on locomotion can be biphasic, observable in the same experiment.

AB  - The development of effective antidotes against organophosphates such as dichlorvos has been a persistent challenge over the past decades. Therapy of organophosphate poisoning is based on the administration of atropine and oxime as standard antidotes. The present study was undertaken to evaluate the ability of sodium bicarbonate to improve protective effects of standard antidotes in rats poisoned with dichlorvos. The aim of this experiment was to establish the correlation between protective effects and biochemical parameters relevant for acid-base status. In order to examine the protective effect of both standard antidotes and their combinations, groups of experimental animals were poisoned subcutaneously with increasing doses of dichlorvos. Immediately thereafter, rats were treated with atropine 10 mg/kg intramuscularly, oximes 10 mg/kg intramuscularly and sodium bicarbonate 3 mmol/kg intraperitoneally. These antidotes were administered either as single doses or in combinations. In the biochemical part of the experiments, rats were poisoned with dichlorvos 1.3 LD50 (10.64 mg/kg) subcutaneously and immediately thereafter treated with atropine 10 mg/kg intramuscularly, oximes (trimedoxime or obidoxime) 10 mg/kg intramuscularly and sodium bicarbonate 3 mmol/kg intraperitoneally either as single doses or in combinations. Parameters relevant for acid-base status were measured 10 minutes after the administration of antidotes. The results of our study indicate that addition of sodium bicarbonate to standard antidotes significantly improves protective effects of atropine, obidoxime and trimedoxime. Correlation between protection and biochemical outcome is clearly evident when sodium bicarbonate is being added to atropine.

AB  - Benzodiazepines are well established as inhibitory modulators of memory processing. This effect is especially prominent when applied before the acquisition phase of a memory task. This minireview concentrates on the putative subtype selectivity of the acquisition-impairing action of benzodiazepines. Namely, recent genetic studies. and standard behavioral tests employing subtype-selective ligands pointed to the predominant involvement of two subtypes of benzodiazepine binding sites in memory modulation. Explicit memory learning seems to be affected through the GABA A receptors containing the α 1 and α 5 subunits, whereas the effects on procedural memory can be mainly mediated by the α 1 subunit. The pervading involvement of the α 1 subunit in memory modulation is not at all unexpected because this subunit is the major subtype, present in 60% of all GABA A receptors. On the other hand, the role of α 5 subunits, mainly expressed in the hippocampus, in modulating distinct forms of memory gives promise of selective pharmacological coping with certain memory deficit states.

AB  - The aim of the study was to examine antidotal potency of trimedoxime in mice poisoned with three direct dimethoxy-substituted organophosphorus inhibitors. In order to assess the protective efficacy of trimedoxime against dichlorvos, heptenophos or monocrotophos, median effective doses and efficacy half-times were calculated. Trimedoxime (24 mg/kg intravenously) was injected 5 min. before 1.3 LD50 intravenously of poisons. Activities of brain, diaphragmal and erythrocyte acetylcholinesterase, as well as of plasma carboxylesterases were determined at different time intervals (10, 40 and 60 min.) after administration of the antidotes. Protective effect of trimedoxime decreased according to the following order: monocrotophos > heptenophos > dichlorvos. Administration of the oxime produced a significant reactivation of central and peripheral acetylcholinesterase inhibited with dichlorvos and heptenophos, with the exception of erythrocyte acetylcholinesterase inhibited by heptenophos. Surprisingly, trimedoxime did not induce reactivation of monocrotophos-inhibited acetylcholinesterase in any of the tissues tested. These organophosphorus compounds produced a significant inhibition of plasma carboxylesterase activity, while administration of trimedoxime led to regeneration of the enzyme activity. The same dose of trimedoxime assured survival of experimental animals poisoned by all three organophosphorus compounds, although the biochemical findings were quite different.

Special attention was paid to the influence of co-administration of sodium bicarbonate on acid-base status in experimental animals poisoned with dichlorvos (1.3 LD50 sc). Coadministration of sodium bicarbonate significantly increased protective effect of standard antidotes in rats poisoned with dichlorvos. Sodium bicarbonate given along with atropine/oxime produced an increase in blood pH value and correction of acidosis. In conclusion, correlation between protective effect and biochemical outcome was evident when sodium bicarbonate was added to antidotes.

AB  - Oral administration of the chloroform extract from Tanacetum larvatum (Griseb. ex Pant.) Kanitz caused a dose-dependent anti-inflammatory effect in the carrageenan-induced rat paw oedema test. The obtained anti-inflammatory effect was 8.6, 32.8, 37.0 and 49.5% for the extract doses of 25, 50, 100 and 200 mg/kg, respectively, being statistically significant at a dose of 50 mg/kg. Indomethacin had a strong anti-inflammatory effect of 73.4% at a dose of 8 mg/kg, but large gastric lesions were detected. When the plant extract in the highest tested dose (200 mg/kg) was concomitantly given with indomethacin, the anti-inflammatory effect was slightly enhanced, but the gastric lesions were significantly reduced. The anti-inflammatory and anti-ulcer activity may be mainly due to the inhibition of DNA binding of the transcription factor NF-kappaB by components of the plant extract. This was proven in an electrophoretic mobility shift assay at a concentration of 50 mug/ml. Due to its anti-inflammatory as well as anti-ulcer effects, Tanacetum larvatum should especially be used combined with those drugs that are known both for their strong anti-inflammatory activities and the ulcerogenic side effects such as NSAIDs.

AB  - The aim of this study was to investigate the efficacy of four pyridinium oximes - pralidoxime (PAM-2), trimedoxime (TMB-4), obidoxime (LuH-6) and HI-6 - alone or in combination with memantine and its principal metabolite 1-amino-3-hydroxymethyl-5-methyl adamantane (Mrz 2/373) against soman in mice. Male Albino mice were pretreated iv with oximes and adamantanes at various times before 1.3 LD-50 of soman iv in order to obtain their ED-50t. In a separate experiment, the brain, dia­phragmai and erythrocytic acetylcholinesterase and plasma carboxylesterase activities were determined after sacrificing mice 5 min after soman 0.75 LD-50. Oxime HI-6 (ED-50 value at 5 min before soman) and adamantanes were administered 5 min before soman. In the combination regimens and in the biochemical experiments the dose of memantine and Mrz 2/373 was fixed at 10 mg/kg iv. Along the tested time intervals, HI-6 afforded the best protection of experimental animals, and calculated EDSOo value of HI-6 was 7.96 µmol/kg. Memantine significantly (up to 9 times) de­creased ED-500 values of all the oximes used, with the exception of TMB-4. Among tested tis­sues, the highest recovery of inhibited acetylcholinesterase was obtained in the diaphragm. Co-administration of adamantanes (memantine, Mrz 2/373) produced a statistically significant in­crease in the erythrocyte acetylcholinesterase activity. It could be concluded that memantine antidotal efficacy could be ascribed to the protection of acetylcholinesterase activity. .
AB  - Pored činjenice daje oksim HI-6 najefikasniji u antagonizovanju toksičnih efekata somana, terapija trovanja ovim nervnim bojnim otrovom još nije u potpunosti zadovoljavajuća. Dosadašnji eksperimenti sa memantinom su pokazali da ovaj derivat adamantana potencira terapijski efekat standardnih antidota pri trovanju organofosfornim jedinjenjima. U ovom radu ispitivana je antidotska efikasnost piridinijumskih oksima - pralidoksima, trimedoksima, obidoksima i HI-6, kao i njihovih kombinacija sa memantinom ili njegovim aktivnim metabolitom Mrz 2/373 u miševa trovanih somanom. Radi dobijanja parametara zaštitne efikasnosti antidota, albino miševima mužjacima su iv aplikovane rastuće doze antidota u određenim vremenskim intervalima ( 1 -60 min) pre 1,3 LD-50 iv somana. Aktivnosti acetilholinesteraze mozga, dijafragme i eritrocita, kao i karboksilesteraza plazme, određivane su nakon iv primene adamantana (10 mg/kg) i/ili oksima HI-6 (3,1 mg/kg; 7,96 µmol/kg) datih 5 min pre 0,75 LD-50 iv somana. Primena oksima HI-6 je obezbedila najbolju zaštitu eksperimentalnih životinja, a srednja efektivna doza u nultom vremenu ED-500 iznosila je 7,96 µmol/kg. Kada je primenjen u kombinaciji sa oksimima, memantin je doveo do značajnog (oko 9 puta) smanjenja HD-500 vrednosti svih oksima, osim trimedoksima. ali je zato poluvreme efikasnosti trimedoksima povećano 4,82 puta. Značajan porast acetilholinesteraze dijafragme dobijen je primenom HI-6, memantina kao i njihove kombinacije. U odnosu na grupu koja je primila samo soman, aktivnost acetilholi­nesteraze eritrocita bila je značajno veća u grupama kojima su davani adamantani i/ili HI-6. Nijedan od primenjenih tretmana nije doveo do statistički značajnog povećanja aktivnosti acetilholinesteraze mozga i karboksilesteraza plazme. Bolji zaštitni efekt kombinacija oksima i memantina u odnosu na same oksime mogao bi se pripisati antikonvulzivnom potencijalu memantina, koji je nekompetitivni antagonista NMDA receptora, ali i izvesnoj zaštiti aktivnog centra acetilholinesteraze dijafragme.
