ABSTRACT
ABSTRACT Objective: To evaluate the effectiveness of the menthol package (lip hydration and ice popsicles) compared to a package of non-menthol measures (lip hydration and ice popsicles) as a way to relieve thirst in patients in the Anesthetic Recovery Room. Method: Randomized and parallel trial study, with 120 patients randomized patients in an experimental group - menthol measurements (n=59) and control group - measures without menthol (n = 61). Results: There was a significant (p<0.05) decrease in intensity, hydration, dryness and taste in the oral cavity between the three moments of assessment/intervention in the two groups. The difference was significant in the experimental group for thirst intensity at the second assessment/intervention point (p<0.05) after a single administration of the menthol package. Conclusion: There was a reduction in thirst intensity in both groups. Patients who received menthol packages showed a significant decrease in intensity after a single evaluation/intervention time. NCT: 02869139.
RESUMEN Objetivo: Evaluar la efectividad del paquete de medidas mentoladas (hidratación labial y picolé de hielo) comparado a un paquete de medidas no mentoladas (hidratación labial y picolé de hielo) como un método de alivio de la sed en pacientes en la Sala de Recuperación Post-Anestésica. Método: En un ensayo clínico aleatorizado, paralelo, 120 pacientes aleatorizados en un grupo experimental - medidas mentoladas (n=59) y un grupo control - medidas sin el mentol (n=61). Resultados: Hubo una disminución significativa (p<0,05) sobre la intensidad, hidratación, sequedad y gusto en la cavidad oral entre los tres momentos de evaluación/intervención en los dos grupos, indistintamente. La diferencia fue significativa en el grupo experimental para la intensidad de la sed en el segundo momento de la evaluación/intervención (p<0,05) después de una única administración del paquete de medidas mentoladas. Conclusión: Se encontró una reducción de la intensidad de la sed en los dos grupos. Los pacientes que recibieron las medidas mentoladas presentaron una disminución significativa de la intensidad después de un único momento de evaluación/intervención. NCT: 02869139.

The mainstay therapy against leishmaniasis is still pentavalent antimonial drugs; however, the rate of antimony resistance is increasing in endemic regions such as Iran. Understanding the molecular basis of resistance to antimonials could be helpful to improve treatment strategies. This study aimed to recognize genes involved in antimony resistance of Leishmania tropica field isolates. Sensitive and resistant L. tropica parasites were isolated from anthroponotic cutaneous leishmaniasis patients and drug susceptibility of parasites to meglumine antimoniate (Glucantime(R)) was confirmed using in vitro assay. Then, complementary DNA-amplified fragment length polymorphism (cDNA-AFLP) and real-time reverse transcriptase-PCR (RT-PCR) approaches were utilized on mRNAs from resistant and sensitive L. tropica isolates. We identified 2 known genes, ubiquitin implicated in protein degradation and amino acid permease (AAP3) involved in arginine uptake. Also, we identified 1 gene encoding hypothetical protein. Real-time RT-PCR revealed a significant upregulation of ubiquitin (2.54-fold), and AAP3 (2.86-fold) (P<0.05) in a resistant isolate compared to a sensitive one. Our results suggest that overexpression of ubiquitin and AAP3 could potentially implicated in natural antimony resistance.

The mast cell-mediated allergic reactions are involved in many allergic diseases, such as asthma, allergic rhinitis and sinusitis. Stimulation of mast cells initiates the process of degranulation, resulting in the release of mediators such as histamine and an array of inflammatory cytokines. In this report, we investigated the effect of gossypin (a biflavonoid) and suramin (a synthetic polysulphonated naphtylurea) on the mast cell-mediated allergy model, and studied the possible mechanism of their action. Both gossypin and suramin inhibited (P<0.001) compound 48/80-induced systemic anaphylaxis reactions, antiprurities (P<0.001) and reduced the histamine release in rats. Further, both showed significant (P<0.001) protection against rat peritoneal mast cells activated by compound 48/80. Thus, our findings provide evidence that gossypin and suramin inhibit mast cell-derived allergic reactions.
