13. Sistema porta hepático do bagre africano Clarias gariepinus Burchell, 1822 (Clariidae, Siluriformes, Ostariophysii) / Hepatic portal system of the African catfish Clarias gariepinus Burchell, 1822 (Clariidae, Siluriformes, Ostariophysii)
The hepatic portal system of the African catfish Clarias gariepinus Burchell, 1822, was studied considering the macroscopic and microscopic anatomy, by means of several anatomic techniques, including anesthesia, injection of substances recommended to the study of the vascular system (latex, Indian ink, polyvinyl chloride and radiopaque substance), dissection

14. Estudo de metodos multivariados para analise e calibração de espectros
Considering the importance of resolving the chemical analysis mixture problem, a comparative study involving R-mode principal component methods, principal component regression (PCR) and partial least squares (PLS) regression, and the Q-mode principal component method of Imbrie was carried out. Furthermore the K matrix method was also studied. Several pre-pro

15. Estudo do efeito do naproxeno na regeneração da nadadeira caudal do peixe teleosteo Cyprinus carpio (carpa)
The fins of teleosts show a very fast capacity for regeneration, what make them one important and appropriate biologic model for study of the drugs that can affect their development. The rays of fins are formed, for the most part, of collagen and glycosaminoglycans and, as showed on literature reports, some antiinflammatory drugs, steroidal and nonsteroidal,

16. Interação dos anestesicos locais benzocaina, lidocaina e tetracaina com membranas modelo
Among the theories for the mecanism of action of local anesthetics (LA) we can highlight those explaining LA effects upon the sodium channel protein and those which focus on the effects of LA interaction with the lipid membrane phase. Once a direct correlation among LA hydrophobicity (measured by the partition coefficient) and its clinical potency exists, it

17. Benzocaine-Induced Methemoglobinemia: A Potentially Fatal Complication of Transesophageal Echocardiography
We describe the cases of 2 patients who developed benzocaine-induced methemoglobinemia after the administration of benzocaine as premedication for transesophageal echocardiography. The use of intravenous methylene blue resolved the cyanosis in both patients. Physicians who perform procedures involving the application of topical anes thesia need to be aware o

18. Use-dependent inhibition of Na+ currents by benzocaine homologs.
Most local anesthetics (LAs) elicit use-dependent inhibition of Na+ currents when excitable membranes are stimulated repetitively. One exception to this rule is benzocaine, a neutral LA that fails to produce appreciable use-dependent inhibition. In this study, we have examined the use-dependent phenomenon of three benzocaine homologs: ethyl 4-diethylaminoben

19. Contrasting actions of cocaine, local anaesthetic and tetrodotoxin on discharge properties of rat aortic baroreceptors.
1. Effects of cocaine, lignocaine, benzocaine and tetrodotoxin (TTX) on the simultaneously measured pressure- and diameter-discharge frequency relations of single fibre baroreceptors were compared in rat in vitro aortic arch-aortic nerve preparations. 2. Between 1 and 10 microM, cocaine produced selective increases in the pressure threshold shifting the pres

21. Evaluation of an acetic acid ester of monoglyceride as a suppository base with unique properties
The objective of this investigation was to evaluate an acetic acid ester of monoglycerides made from edible, fully hydrogenated palm oil (AC-70) as a suppository based and compare it with a commercially available semisynthetic base (Suppocire AI®). Benzocaine and miconazole were used as model drugs. Suppositories were prepared by the fusion method. The drug

22. Inhibition of Aspergillus growth and aflatoxin release by derivatives of benzoic acid.
A study was conducted to determine the effects of o-nitrobenzoate, p-aminobenzoate, benzocaine (ethyl aminobenzoate), ethyl benzoate, methyl benzoate, salicylic acid (o-hydroxybenzoate), trans-cinnamic acid (beta-phenylacrylic acid), trans-cinnamaldehyde (3-phenylpropenal), ferulic acid (p-hydroxy-3-methoxycinnamic acid), aspirin (o-acetoxy benzoic acid), an

23. The effect of local anaesthetics on the components of the asymmetry current in the squid giant axon.
The effects of local anaesthetics and holding potential on sodium and asymmetry currents were studied in intracellularly dialysed squid giant axons. The asymmetry currents were fractionated into their inactivating and non-inactivating components, and the charge displacements Qi and Qn of the two components were determined for pulse potentials between -20 and

24. Pain evoked by polymodal stimulation of hand veins in humans.
1. To explore the function of the sensory innervation of veins in humans we used a psychophysical approach to study painful and non-painful sensations by applying polymodal stimuli (electrical, stretch, cold/heat and osmotic) inside vascularly isolated hand vein segments before and after blockade of either venous or cutaneous afferents. 2. All modes of stimu
