  • Glossopharyngeal Nerve Block versus Lidocaine Spray to Improve Tolerance in Upper Gastrointestinal Endoscopy

    Co-Authors: Moisés Ortega Ramírez, Benigno Linares Segovia, Marco Antonio García Cuevas, Jorge Luis Sánchez Romero, Illich Botello Buenrostro, Norma Amador Licona, Juan Manuel Guízar Mendoza, Jesús Francisco Guerrero Romero, Víctor Manuel Vázquez Zárate
    Abstract:

    Aim of the Study. To compare the effect of Glossopharyngeal Nerve block with topical anesthesia on the tolerance of patients to upper gastrointestinal endoscopy. Methods. We performed a clinical trial in one hundred patients undergoing upper gastrointestinal endoscopy. Subjects were randomly assigned to one of the following two groups: (1) treatment with bilateral Glossopharyngeal Nerve block (GFNB) and intravenous midazolam or (2) treatment with topical anesthetic (TASS) and intravenous midazolam. We evaluated sedation, tolerance to the procedure, hemodynamic stability, and adverse symptoms. Results. We studied 46 men and 54 women, from 17 to 78 years of age. The procedure was reported without discomfort in 48 patients (88%) in the GFNB group and 32 (64%) in the TAAS group; 6 patients (12%) in GFNB group and 18 (36%) in TAAS group reported the procedure as little discomfort (χ2 = 3.95, P = 0.04). There was no difference in frequency of nausea (4% in both groups) and retching, 4% versus 8% for GFNB and TASS group, respectively (P = 0.55). Conclusions. The use of Glossopharyngeal Nerve block provides greater comfort and tolerance to the patient undergoing upper gastrointestinal endoscopy. It also reduces the need for sedation.

  • Competitive inhibition of the nickel-induced response to choline by calcium ions in single water fibers of the frog Glossopharyngeal Nerve.
    Chemical senses, 1994
    Co-Authors: Yasuyuki Kitada
    Abstract:

    NiCl2 induces a response to choline Cl and enhances the response to CaCl2 in water-sensitive fibers (water fibers) of the frog Glossopharyngeal Nerve. The Ni(2+)-induced choline+ response was inhibited by Ca2+ ions and, conversely, the enhanced Ca2+ response by Ni2+ ions was inhibited by choline+ ions. Hence, there exists a mutual antagonism between Ca2+ and choline+ ions. In the present study, the inhibition of the Ni(2+)-induced choline+ response by Ca2+ ions was investigated quantitatively. The assumption was made that receptors for choline (XCh) exist and that binding of a choline+ ion to XCh brings about a neural response. It was further assumed that the magnitude of the neural response is proportional to the amount of choline-XCh complex minus some constant (the threshold concentration of the choline-XCh complex). The results from analysis of double-reciprocal plot were consistent with the hypothesis that Ca2+ ions compete with choline+ ions for XCh. The dissociation constants for the choline-XCh complex and the CaXCh complex were obtained to be 0.6 M and 7.4 x 10(-5) M, respectively. This result indicates that the affinities of XCh for choline+ and Ca2+ ions are very different. Furthermore, Mg2+ ions did not affect the Ni(2+)-induced choline+ response, an indication that the affinity of XCh is not charge-specific, but is chemically specific. The identification of a competitive inhibitor of the choline+ response provides evidence for existence of a choline-specific receptor at the surface of taste cells that are innervated by the water fibers of the frog Glossopharyngeal Nerve. Differences between the features of the response to choline Cl in the chorda tympani Nerve of the rat and those in the frog Glossopharyngeal Nerve are discussed.

  • Effects of Anions on the Responses to Ca, Mg, and Na in Single Water Fibers of the Frog Glossopharyngeal Nerve
    Olfaction and Taste XI, 1994
    Co-Authors: Yasuyuki Kitada
    Abstract:

    Single water fibers of the frog Glossopharyngeal Nerve respond not only to water but also to salts such as those of Ca, Mg, and Na. The salt taste responses in the water fibers are strongly influenced by anions. In this study, we investigated the role of anions in salt taste reception in single water fibers of the frog Glossopharyngeal Nerve.

  • Parasympathetic postganglionic cells in the Glossopharyngeal Nerve trunk and their relationship to unmyelinated Nerve fibers in the fungiform papillae of the frog.
    The Anatomical record, 1991
    Co-Authors: Katsuhiro Inoue, Yasuyuki Kitada
    Abstract:

    The Glossopharyngeal Nerve of the frog is made up of afferent Nerve fibers and efferent, parasympathetic and sympathetic Nerve fibers. The precise origin and course of the parasympathetic efferent Nerve fibers in the fungiform papillae of the frog's tongue were investigated. We found the ganglionic cells in the lingual branch of the frog Glossopharyngeal Nerve. The surface of the ganglionic cell bodies was partly covered by synaptic endings that impinged upon it. Synaptic endings contained clear synaptic vesicles and large dense-cored vesicles. After cutting of the Glossopharyngeal Nerve proximal to the jugular ganglion, synaptic endings were found to show definite signs of degeneration. These findings led us to the conclusion that the ganglionic cells in the lingual branch of the Glossopharyngeal Nerve are the parasympathetic postganglionic cells. After cutting of the Glossopharyngeal Nerve distal to the jugular ganglion, some unmyelinated Nerve fibers in the fungiform papillae and postganglionic cells in the lingual branch remained intact. These results strongly suggest that the origin of some of the unmyelinated Nerve fibers is the parasympathetic postganglionic cell in the lingual branch.
