37. Preparation, physicochemical characterization and stability evaluation of polymeric nanoparticles containing local anesthetics / Preparo, caracterização fisico-quimica e avaliação da estabilidade de nanoparticulas polimericas contendo anestesicos locais
As principais características desejáveis para um anestésico local incluem longa duração de ação e baixa toxicidade sistêmica. Uma alternativa que tem se mostrado capaz de promover estes efeitos desejáveis é a liberação sustentada de fármacos através da veiculação destes em sistemas carreadores, como as nanopartículas. Nanopartículas polimé

38. Hialuronidase associada à lidocaína com epinefrina em bloqueio pterigomandibular: avaliação da latência, duração e índice de sucesso anestésico, edema facial e abertura bucal / Hyaluronidase with lidocaine and ephinefrine in inferior alveolar nerve block: avaliation of onset time, duration of anaesthetic action, sucess rate, trismus and edema postoperative
The association of local anaesthetic (LA) with hyaluronidase (H) is widely used in ophthalmic anesthesia in order to improve its effectiveness of anesthesia. In dentistry, H 150 UTR/ mL injected concomitantly to LA solution did not enhance the success rate of anesthesia in inferior alveolar nerve (IAN) block and increased postoperative trismus.

39. Levobupivacaine, ropivacaine and lidocaine on the anesthesia eyelid in the horse: evaluation of intraocular pressure, tear production and the effectiveness of anesthesia / Levobupivacaína, ropivacaína ou lidocaína na anestesia palpebral em equinos: avaliação da pressão intra-ocular, da produção lacrimal e da eficácia do bloqueio anestésico
Corneal anesthesia is required in order to evaluate the intraocular pressure (IOP) and eyelid blockades may also be necessary, using local anesthetic agents in horses. The aim of this study was to evaluate the IOP and the corneal touch threshold (CTT) at the central area of the cornea, after eyelid blockades with anesthetic 0.75% ropivacaine, 0.75% levobupiv

41. STEADY STATE AND TIME RESOLVED FLUORESCENCE STUDIES OF LOCAL ANESTHETICS AND FLUOROQUINOLONE ANTIBIOTICS / ESTUDOS DE FLUORESCÊNCIA ESTACIONÁRIA E RESOLVIDA NO TEMPO DE ANESTÉSICOS LOCAIS E DE ANTIBIÓTICOS DA CLASSE DAS FLUOROQUINOLONAS
Durante as últimas décadas tem-se acentuado o desenvolvimento de técnicas de fluorescência e suas aplicações em biociências e biotecnologia. Dada sua alta sensibilidade de detecção, tais técnicas têm-se tornado ferramentas importantes em muitas áreas de pesquisa tais como diagnósticos médicos, análise genética, mapeamento estrutural de célul

42. Prenatal dental care: evaluation of professional knowledge of obstetricians and dentists in the cities of Londrina/PR and Bauru/SP, Brazil, 2004
The purpose of this study was to assess the current knowledge and recommendations of obstetricians and dentists as to the dental care to pregnant patients in the cities of Londrina/PR and Bauru/SP, Brazil. Questionnaires were distributed to professionals of both cities, arguing on the following issues: oral health during pregnancy; contact between prenatal c

43. Benzocaína, um estudo computacional
Nowadays the local anesthetics drugs are widely used, including benzocaine a local anesthetic of topic use. Its active ingredient is on the market in various ointments and creams. The action of local anesthetics was tested extensively, and one of the assumptions of the Hille s receptor modulator, indicates that the local anesthetics acts primarily by the inh

44. Cardiovascular changes during oral implant surgeries under local anesthesia and sedative premedication / Alterações cardiovasculares em cirugias para a colocação de implantes dentários sob anestesia local pré-medicação ansiolítica
The purpose of this controlled and double-blind trial was to evaluate cardiovascular effects induced by pterigomandibular block of local anesthetic (LA) 2 % lidocaína hydrochloride with epinephrine, followed administration of benzodiazepine (midazolam 15mg on hour prior) or placebo during the surgical phase of placement of the lower bilateral dental implant

45. Anestésicos locais: interação com membranas biológicas e com o canal de sódio voltagem-dependente
Many theories about the mechanism of action of local anesthetics (LA) are described in the literature. Two types of theories can be distinguished: those that focus on the direct effects of LA on their target protein in the axon membranes, i.e. the voltage-gated sodium channel and the ones that take into account the interaction of anesthetic molecules with th

46. Análise funcional e histológica da utilização da hialuronidase durante a anestesia local em nervo ciático de ratos / Functional and histological analysis of hyaluronidase use during local anesthesia of the rat sciatic nerve
The concomitant use of the enzyme hyaluronidase (H) and local anesthetics (LA) is widely employed in ophthalmology in order to improve the effectiveness of anesthesia; in dentistry, however, this association did not seem advantageous. A new protocol was tested with the aim of drawing out local anesthesia without supplementary anesthesia. This possibility is

47. Inhibition mechanism of the nicotinic acetylcholine receptor α3β4 tacrine / Mecanismos de inibição do receptor nicotínico de acetilcolina α3β4 pela tacrina
Neuronal nicotinic acetylcholine (cholinergic) receptors (nAChRs) are integral membrane proteins and belong to the family of ligand-gated cation channels composed by α and β subunits. These receptors play a key role in the signal transmission between neurons in the central and peripheral nervous system. The α3β4 subtype, for example, is t

48. Liposomal lidocaine prepared in a scale-up procedure : formulation, characterization and biological tests / Lidocaina lipossomal produzida em processo escalonavel : formulação, caracterização e testes biologicos
Anestésicos locais se caracterizam pela capacidade de abolir a dor sem a perda da consciência; contudo, são moléculas pequenas facilmente redistribuídas do sítio de injeção, limitando a duração da anestesia. Uma maneira de prolongar a anestesia é encapsular os anestésicos locais com sistemas carreadores como lipossomas, que permaneçam no sítio
