AB  - poorly controlled by current treatments. It represents major therapeutic concern and reduces patients quality of life. Numerous chemical mediators are present in trigeminal ganglia, and GABA is most common inhbitory neurotransmitter. Due to different subunit combinations, GABA can show diversity of pharmacological effects. GABAA receptors containing α6 subunit are located in trigeminal ganglia, and their reduction by small interfering RNA increases inflammatory temporomandibular and myofascial pain in rats. One of the most common orofacial pain states like trigeminal neuralgia or trigeminal neuropathy begin in trigeminal ganglia. We thus hypothesized that enhancing GABAA receptors containing the α6 subunit activity may help in neuropathic syndromes originating from the trigeminal system. Selective modulators that activate this specific receptor population are not commercially available. In this doctoral dissertation we used recently developed deuterated pyrazoloquinolinone compound, (DK-I-56-1) that selectively activates α6 subunit of GABAA receptors. Here, we performed a detailed pharmacokinetic analysis of DK-I-56-1 on animal experimental model. Both plasma and brain tissue kinetics of DK-I-56-1 were relatively slow, with half-lives of 6 h and 13 h, respectively, enabling the persistence of estimated free brain concentrations in the range 10-300 nM throughout a 24-h period. We confirmed that chronic constriction injury of infraorbital nerve is considered a reliable experimental animal model for trigeminal neuropathic pain. Results were obtained on IoN-CCI protocol in hypersensitive rats dosed intraperitoneally with 10 mg/kg DK-I-56-1 or DK-I-87-1, structurally similar pyrazoloquinolinone compound that can not induce GABA currents on α6 containing receptors...
AB  - Trigeminalni neuropatski bol je hronično bolno stanje orofacijalne regije koje nastaje kao posledica povrede trigeminalnog živca. Ova vrsta bola loše ili uopšte ne reaguje na terapiju, te njegovo lečenje predstavlja veliki terapijski problem koji utiče kvalitet života pacijenta. U trigeminalnom ganglionu eksprimiran je veliki broj hemijskih medijatora, a GABA je najznačajniji inhibitorni neurotransmiter. Zbog velikog broja podjedinica i njihovih različitih kombinacija, postoji veliki broj efekata koji GABA ostvaruje. U trigeminalnom ganglionu postoje GABAA receptori koji sadrže α6 podjedinicu. Smanjenje ove podjedinice primenom male interferirajuće RNK pojačava bolni odgovor kod eksperimentalnh životinja na modelima miofacijalnog i inflamatornog bola temporomandibularnog zgloba. Trigeminalni ganglion je supstrat za razvoj većeg broja patoloških stanja koje se sreću u stomatologiji, kao što su trigeminalna neuralgija i trigerminalna neuropatija. Hipoteza ove doktorske disertacije je bila da pojačavanje aktivnosti GABAA receptora koji sadrže α6 podjedinicu utiče na smanjenje bolnog odgovora u modelu trigeminalnog neuropatskog bola. Lekovi koji potenciraju aktivnost ove grupe receptora nisu dostupni u kliničkoj praksi. U ovoj doktorskoj disertaciji korišćen je DK-I-56-1, novosintetisani selektivni modulator α6 podjedinice GABAA receptora, koji pripada grupi deuterisanih pirazolohinolinona. Sprovedena je detaljna farmakokinetička analiza ovog jedinjenja na animalnom eksperimentalnom modelu. Dobijeni rezultati pokazuju da je kinetika ovog jedinjenja u plazmi i mozgu relativno spora, sa poluvremenom eliminacije od 6 h odnosno 13 h, pri čemu je postignuta slobodna koncentracija u mozgu u rasponu 10-300 nM. Ovakav farmakokinetički profil je podesan za ispitivanje u protokolima ponavljane primene...

AB  - gamma-Aminobutyric acid type A (GABA(A)) receptors containing the alpha 6 subunit are located in trigeminal ganglia, and their reduction by small interfering RNA increases inflammatory temporomandibular and myofascial pain in rats. We thus hypothesized that enhancing their activity may help in neuropathic syndromes originating from the trigeminal system. Here, we performed a detailed electrophysiological and pharmacokinetic analysis of two recently developed deuterated structurally similar pyrazoloquinolinone compounds. DK-I-56-1 at concentrations below 1 mu M enhanced gamma-aminobutyric acid (GABA) currents at recombinant rat alpha 6 beta 3 gamma 2, alpha 6 beta 3 delta and alpha 6 beta 3 receptors, whereas it was inactive at most GABA(A) receptor subtypes containing other alpha subunits. DK-I-87-1 at concentrations below 1 mu M was inactive at alpha 6-containing receptors and only weakly modulated other GABA(A) receptors investigated. Both plasma and brain tissue kinetics of DK-I-56-1 were relatively slow, with half-lives of 6 and 13 hr, respectively, enabling the persistence of estimated free brain concentrations in the range 10-300 nM throughout a 24-hr period. Results obtained in two protocols of chronic constriction injury of the infraorbital nerve in rats dosed intraperitoneally with DK-I-56-1 during 14 days after surgery or with DK-I-56-1 or DK-I-87-1 during 14 days after trigeminal neuropathy were already established, demonstrated that DK-I-56-1 but not DK-I-87-1 significantly reduced the hypersensitivity response to von Frey filaments. Significance Neuropathic pain induced by trigeminal nerve damage is poorly controlled by current treatments. DK-I-56-1 that positively modulates alpha 6 GABA(A) receptors is appropriate for repeated administration and thus may represent a novel treatment option against the development and maintenance of trigeminal neuropathic pain.

AB  - Introduction. The material used for root-end filling has to be biocompatible with adjacent periapical tissue and to stimulate its regenerative processes. Tricalcium silicate cement (TSC), as a new dental material, shows good sealing properties with dentin, high compression strengths and better marginal adaptation than commonly used root-end filling materials. Although optimal postoperative healing of periapical tissues is mainly influenced by characteristics of end-root material used, it could sometimes be affected by the influence of systemic diseases, such as diabetes mellitus (DM). Case report. We presented apical healing of the upper central incisor, retrofilled with TSC, in a diabetic patient (type 2 DM) with peripheral neuropathy. Standard root-end resection of upper central incisor was accompanied by retropreparation using ultrasonic retrotips to the depth of 3 mm and retrofilling with TSC. Postoperatively, the surgical wound healed uneventfully. However, the patient reported undefined dull pain in the operated area that could possibly be attributed to undiagnosed intraoral diabetic peripheral neuropathy, what was evaluated clinically. Conclusion. Although TSC presents a suitable material for apical root-end filling in the treatment of chronic periradicular lesions a possible presence of systemic diseases, like type 2 DM, has to be considered in the treatment outcome estimation.

Trikalcijum silikatni cement (TSC), kao novi dentalni materijal, pokazuje dobro zaptivanje, visoku kompresivnu snagu i bolju ivičnu adaptaciju u odnosu na standardno korišćene materijale za retroopturaciju. Iako postoperativno zarastanje periapikalnog tkiva najviše zavisi od karakteristika materijala za retroopturaciju, ponekad na uspeh zarastanja može uticati i prisustvo neke sistemske bolesti kao što je dijabetes melitus (DM). Prikaz bolesnika. Prikazali smo apikalno zarastanje u predelu gornjeg centralnog sekutića, nakon retroopturacije sa TSC, kod bolesnika sa DM tipa 2 i prisutnom perifernom neuropatijom. Standardna resekcija korena gornjeg centralnog sekutića bila je urađena retropreparacijom ultrazvučnim nastavcima do dubine od 3 mm i retrogradnom opturacijom sa TSC. Zarastanje postoperativne regije bilo je u fiziološkim granicama. Bolesnik se, međutim, žalio na nedefinisan, tup bol u predelu operisane regije koji je verovatno bio povezan sa nedijagnostikovanom intraoralnom dijabetičnom perifernom neuropatijom, što je potvrđeno kliničkim nalazom.
