RESUMO

Introduction: Anti-inflammatory drugs are being utilized to treat cancer because of its inflammatory microenvironment. Objective: The objective of this study is to investigate the antioxidant potential of indomethacin and its genotoxicity, since free or loaded in polymeric nanocapsules using MCF-7 (human breast cancer) cells as an in vitro model. Method: Development of indomethacin-loaded polyepsilon-caprolactone (PCL) nanocapsules by interfacial deposition method. It is characterized by pH determination by potentiometer, mean diameter and polydispersity index by dynamic light scattering; zeta potential by electrophoretic mobility; encapsulation efficacy by high performance liquid chromatography method; corona effect formation; 2',7'-dichlorofluorescin diacetate (DCFH-DA) method by spectrofluorimetric assay; nitric oxide (NO) determination by spectrophotometric and genotoxicity assay by plasmid DNA cleavage method. Results: The results showed a mild acidic pH (4.78 ± 0.10), sizes around 200 nm and PDI<0.2 with a zeta potential around -20 mV and encapsulation efficiency of 99% (1 mg mL-1), showing a dose-dependent corona formation profile in 24h incubation. Conclusion: DCFH-DA assay showed no production of reactive oxygen species (ROS) while NO determination showed that Ind-OH-NC from 26.7 to 100 µM increased reactive nitrogen species (RNS), demonstrating antioxidant potential against MCF-7 cells. No sample at the concentrations evaluated induced DNA cleavage, being considered a safe treatment

RESUMO

ABSTRACT Objective: To characterize the number and methods of closure of Persistent Ductus Arteriosus (PDA) over a span of 16 years in a third level maternity hospital. Methods: Retrospective study of neonates born between January 2003 and Deccember 2018, who underwent ductus arteriosus closure by pharmacological, surgical and/or transcatheter methods. Gestational age, birth weight, number and methods of closures per year were evaluated. The success rate of the pharmacologic method was calculated, as well as the mortality rate. The association between mortality and birthweight, treatment used and treatment failure was explored. Results: There were 47,198 births, 5,156 were preterm, 325 presented PDA and 106 were eligible for closure (median gestational age - 27 weeks, birthweight <1000 g - 61%). Frequency of PDA closure decreased during the study period, especially starting in 2010. Success rate with pharmacologic treatment was 62% after the first cycle and 74% after the second. After drug failure, 12 underwent surgical ligation and two underwent transcatheter closure. Exclusive surgical ligation was indicated in four infants. Ibuprofen replaced indomethacin in 2010, and acetaminophen was used in three infants. Among the 106 infants, hospital mortality was 12% and it was associated with birthweight <1000 g (13/65 <1000 vs. 0/41 >1000 g; p=0.002) and with failure in the first pharmacologic treatment cycle (13/27 with failure, vs. 0/75 without failure; p<0.001). Conclusions: The national consensus published in 2010 for the diagnosis and treatment of PDA in preterm infants led to a decrease in the indication for closure. Pharmacological closure was the method of choice, followed by surgical ligation. Birthweight <1000 g and first cycle of pharmacologic treatment failure were associated with higher mortality.


RESUMO Objetivo: Caraterizar o número e métodos de fechamento de canal arterial durante 16 anos numa maternidade de nível terciário. Métodos: Estudo retrospetivo de nascidos entre 01 de janeiro de 2003 a 31 de dezembro de 2018 submetidos a fechamento do canal arterial por métodos farmacológico, cirúrgico e/ou percutâneo. Avaliaram-se idade gestacional, sexo, peso ao nascimento, número de fechamentos por ano e método utilizado. Aferiram-se as taxas de sucesso de método farmacológico e de mortalidade e sua associação com peso ao nascer, fármaco utilizado e insucesso do fechamento. Resultados: Verificaram-se 47.198 recém-nascidos, 5.156 prematuros, dos quais 325 com canal arterial patente, sendo 106 com indicação para fechamento (idade gestacional mediana 27 semanas, peso <1000 g em 61%). Verificou-se diminuição do número de fechamentos ao longo dos anos, sobretudo a partir de 2010. O fechamento ocorreu em 62% após primeiro ciclo de tratamento farmacológico e em 74% após segundo. Após insucesso farmacológico, 12 realizaram ligadura cirúrgica e dois, fechamento percutâneo. Houve indicação de ligadura cirúrgica exclusiva em quatro. O ibuprofeno substituiu a indometacina em 2010. O acetaminofen foi usado em três doentes. A mortalidade nos 106 pacientes foi de 12%, associando-se ao peso ao nascer (13/65 <1000 vs. 0/41 >1000 g; p=0,002) e à falha do primeiro ciclo de tratamento farmacológico (13/27 com falha vs. 0/75 com sucesso; p<0,001). Conclusões: Consenso nacional de 2010 para diagnóstico e tratamento do canal arterial nos prematuros levou à diminuição do número de fechamentos desse canal. O fechamento farmacológico foi o método mais utilizado, seguido da ligadura cirúrgica. Peso <1000 g e falha no primeiro ciclo de fechamento farmacológico se associaram à maior mortalidade.

RESUMO

Este trabajo se fundamenta en la evaluación de la actividad antiinflamatoria de extractos de sofrito de tomate, así como de compuestos estándares de la dieta mediterránea, usando un modelo experimental optimizado basado en larvas de pez cebra. La migración de neutrófilos en larvas de pez cebra de 96 horas post fertilización se indujo mediante una lesión y se potenció añadiéndole lipopolisacárido, dicha migración se visualizó y cuantificó mediante análisis de imagen. El efecto antiinflamatorio del extracto de tomate y de los compuestos utilizados fue correlacionado porcentualmente por la disminución de la migración de los neutrófilos. Los resultados muestran que el extracto de tomate presentó una reducción en la migración de neutrófilos de 40 % respecto al grupo control. Por otra parte, el ácido clorogénico y la cianidina presentes en el sofrito de tomate utilizados como estándares presentaron una disminución de la migración de neutrófilos de un 66,7 % y 62,5 % respectivamente. Estos porcentajes son comparables a los resultados observados en ensayos con drogas antiinflamatorias como la indometacina y piroxicam. Los resultados muestran que el extracto de sofrito de tomate presenta posible actividad antinflamatoria demostrada por la reducción de la migración de neutrófilos, además el modelo se mostró sensible y válido para ser aplicado en matrices alimentarias complejas(AU)


The main of this study was to evaluate the anti-inflammatory activity of tomato sofrito extracts, as well as standard compounds present in the Mediterranean diet, using an optimized experimental model based on zebrafish larvae. Neutrophil migration in zebrafish larvae 96 hours post fertilization was induced by a cut in the caudal fin and enhanced by adding lipopolysaccharide and was visualized and quantified by image analysis. The anti-inflammatory effect of tomato extract and the compounds used was correlated by the percentage decrease in the migration of neutrophils. The results showed that, tomato extract showed a reduction in neutrophil migration of 40% compared to the control group. Moreover, chlorogenic acid and cyanidin present in tomato sofrito sauce showed a decrease in neutrophil migration of 66.7% and 62.5% respectively. These percentages are comparable to the results observed in trials with anti-inflammatory drugs such as indomethacin and piroxicam. The results show that tomato sofrito extract has possible anti-inflammatory activity demonstrated by the reduction of neutrophil migration, furthermore the model was sensitive and valid to be applied in complex food matrices(AU)

RESUMO

Las mujeres han sido tratadas por décadas con testosterona intentando aliviar una gran variedad de síntomas con riesgos y beneficios inciertos. En la mayoría de los países, la testosterona se prescribe "off-label", de modo que las mujeres están utilizando compuestos y dosis ideadas para tratamientos en hombres. En este sentido, varias sociedades médicas de distintos continentes adoptaron recientemente por consenso una toma de posición sobre los beneficios y potenciales riesgos de la terapia con testosterona en la mujer, explorar las áreas de incertidumbre e identificar prácticas de prescripción con potencial de causar daño. Las recomendaciones con respecto a los beneficios y riesgos de la terapia con testosterona se basan en los resultados de ensayos clínicos controlados con placebo de al menos 12 semanas de duración. A continuación se comentan las recomendaciones. (AU)


There are currently no clear established indications for testosterone replacement therapy for women. Nonetheless, clinicians have been treating women with testosterone to alleviate a variety of symptoms for decades with uncertainty regarding its benefits and risks. In most countries, testosterone therapy is prescribed off-label, which means that women are using testosterone formulations or compounds approved for men with a modified dose for women. Due to these issues, there was a need for a global Consensus Position Statement on testosterone therapy for women based on the available evidence from placebo randomized controlled trials (RCTs). This Position Statement was developed to inform health care professionals about the benefits and potential risks of testosterone therapy intended for women. The aim of the Consensus was to provide clear guidance as to which women might benefit from testosterone therapy; to identify symptoms, signs, and certain conditions for which the evidence does not support the prescription of testosterone; to explore areas of uncertainty, and to identify any prescribing practices that have the potential to cause harm.

RESUMO

Abstract Nonsteroidal anti-inflammatory drugs (NSAID) are among the aggressive factors causing gastric ulcer. They cause oxidative damage in the gastric tissue and lead to intracellular calcium deposition. Lercanidipine is a calcium channel blocker derived from the third generation dihydropyridine. The aim of this study is to analyse the effect of lercanidipine on indomethacin-induced gastric ulcers. A total of 24 albino Wistar male rats were divided into four groups; those who received indomethacin 25 mg/kg (IND), 5 mg mg/kg lercanidipine +25 mg/kg indomethacin (LC-5), 10 mg/kg lercanidipine+25mg/kg indomethacin (LC-10) and healthy rats who received 0.5 mL distilled water. Six hours after the application of indomethacin, the animals were sacrificed by high dose thiopental sodium. The stomachs of the animals were excised to perform a macroscopic analysis and the ulcerous region was measured on millimeter paper. All the stomachs were subjected to a biochemical analysis. Macroscopic analysis revealed hyperaemia on the gastric surface of the indomethacin group. Ulcerous tissues formed by oval, circular or irregular mucosal defects in varying diameters and depths were observed on the whole surface of the stomach. Hyperaemia was lower and ulcerous region was smaller in groups LC-5 and LC-10 compared to IND group. Malondialdehyde and myeloperoxidase levels were significantly lower and total glutathione and cyclooxygenase-1 activity were higher in groups LC-5 and LC-10. Lercanidipine did not change the cyclooxygenase-2 activity. Lercanidipine in doses 10 mg/kg is more effective compared to 5 mg/kg. Lercanidipinine can be useful in the treatment of NSAID-induced gastric damage.

RESUMO

This study aimed to analyze the antiarthritic activity of ginkgolic acid against the Complete Freund's Adjuvant (CFA)-induced arthritis in rats. Arthritis was induced through an intradermal injection of CFA (0.1 mL) at the right hind footpad of adult Wistar Albino rats. Ginkgolic acid was administered orally at doses of 25 mg/kg and 50 mg/kg, respectively, once daily via gavage for 25 days upon inducing arthritis. Indomethacin was administered orally at a dose of 3 mg/kg twice in a week which served as positive control group. The animals were sacrificed and subjected to biochemical and histopathological analysis upon completion of treatment. Ginkgolic acid was able to reverse the arthritic effect (p < 0.01) induced by CFA in a dose dependent manner. Swelling of paw, thymus and spleen index, serum biomarker levels, and pro-inflammatory cytokines were significantly reduced (p < 0.01) by the acid whereas the antioxidant enzyme activities were remarkably restored. The histopathological findings were in agreement with the biochemical results. The results indicate that the antioxidant and anti-inflammatory properties of ginkgolic acid can be credited to the antiarthritic effects, and it can be promoted as a potential agent for therapeutic use against osteoarthritis

RESUMO

The neurochemical mechanisms underlying neuropathic pain (NP) are related to peripheral and central sensitization caused by the release of inflammatory mediators in the peripheral damaged tissue and ectopic discharges from the injured nerve, leading to a hyperexcitable state of spinal dorsal horn neurons. The aim of this work was to clarify the role played by cyclooxygenase (COX) in the lesioned peripheral nerve in the development and maintenance of NP by evaluating at which moment the non-steroidal anti-inflammatory drug indomethacin, a non-selective COX inhibitor, attenuated mechanical allodynia after placing one loose ligature around the nervus ischiadicus, an adaptation of Bennett and Xie's model in rodents. NP was induced in male Wistar rats by subjecting them to chronic constriction injury (CCI) of the nervus ischiadicus, placing one loose ligature around the peripheral nerve, and a sham surgery (without CCI) was used as control. Indomethacin (2 mg/kg) or vehicle was intraperitoneally and acutely administered in each group of rats and at different time windows (1, 2, 4, 7, 14, 21, and 28 days) after the CCI or sham surgical procedures, followed by von Frey's test for 30 min. The data showed that indomethacin decreased the mechanical allodynia threshold of rats on the first, second, and fourth days after CCI (P<0.05). These findings suggested that inflammatory mechanisms are involved in the induction of NP and that COX-1 and COX-2 are involved in the induction but not in the maintenance of NP.

RESUMO

Abstract Objectives: Infection, inflammation and bone resorption are closely related events in apical periodontitis development. Therefore, we sought to investigate the role of cyclooxygenase (COX) in osteoclastogenesis and bone metabolism signaling in periapical bone tissue after bacterial lipopolysaccharide (LPS) inoculation into root canals. Methodology: Seventy two C57BL/6 mice had the root canals of the first molars inoculated with a solution containing LPS from E. coli (1.0 mg/mL) and received selective (celecoxib) or non-selective (indomethacin) COX-2 inhibitor. After 7, 14, 21 and 28 days the animals were euthanized and the tissues removed for total RNA extraction. Evaluation of gene expression was performed by qRT-PCR. Statistical analysis was performed using analysis of variance (ANOVA) followed by post-tests (α=0.05). Results: LPS induced expression of mRNA for COX-2 (Ptgs2) and PGE2 receptors (Ptger1, Ptger3 and Ptger4), indicating that cyclooxygenase is involved in periapical response to LPS. A signaling that favours bone resorption was observed because Tnfsf11 (RANKL), Vegfa, Ctsk, Mmp9, Cd36, Icam, Vcam1, Nfkb1 and Sox9 were upregulated in response to LPS. Indomethacin and celecoxib differentially modulated expression of osteoclastogenic and other bone metabolism genes: celecoxib downregulated Igf1r, Ctsk, Mmp9, Cd36, Icam1, Nfkb1, Smad3, Sox9, Csf3, Vcam1 and Itga3 whereas indomethacin inhibited Tgfbr1, Igf1r, Ctsk, Mmp9, Sox9, Cd36 and Icam1. Conclusions: We demonstrated that gene expression for COX-2 and PGE2 receptors was upregulated after LPS inoculation into the root canals. Additionally, early administration of indomethacin and celecoxib (NSAIDs) inhibited osteoclastogenic signaling. The relevance of the cyclooxygenase pathway in apical periodontitis was shown by a wide modulation in the expression of genes involved in both bone catabolism and anabolism.

RESUMO

ABSTRACT Objective: To assess the efficacy and safety of atosiban in pregnant women with risk of preterm delivery as compared to nifedipine, indomethacin, terbutaline, fenoterol and placebo. Materials and methods: A systematic literature review was carried out in eight electronic databases, including Medline, Central, and Embase, using free and standardized search terms. Outcomes assessment included time delay until delivery, neonatal mortality, ratio of adverse maternal events, and ratio of neonatal complications. The quality of the evidence was evaluated per study and for the body of evidence and, whenever feasible, the information was synthesized into a meta-analysis. Alternatively, a narrative summary was presented. Results: Eleven studies were included. Atosiban did not show any statistically significant differences in terms of delaying delivery versus other uterine contraction inhibitors. The neonatal mortality was lower compared to indomethacin (RR = 0.21; 95% CI: 0.05 to 0.92), and the percentage of total maternal adverse events was lower compared to fenoterol (RR = 0.16; 95% CI: 0.08 to 0.31), nifedipine (RR = 0.48; 95% CI: 0.3 to 0.78), and terbutaline (RR = 0.44; 95% CI: 0.28 to 0.71). Conclusions: Atosiban has similar efficacy for delivery delay in patients with risk of preterm delivery as compared to other agents (moderate certainty), showing some advantages regarding neonatal mortality (low certainty) versus indomethacin, and compared to fenoterol, nifedipine and terbutaline in terms of maternal adverse events (moderate certainty).

Materiales y métodos: se realizó una revisión sistemática de la literatura en ocho bases de datos electrónicas (Medline, Central, Embase, entre otras), mediante términos de búsqueda libres y estandarizados. Los desenlaces evaluados incluyeron tiempo de retardo del parto, mortalidad neonatal, proporción de eventos adversos maternos y proporción de complicaciones neonatales. Se evaluó la calidad de la evidencia por estudio y para el cuerpo de evidencia, y se sintetizó la información mediante metaanálisis, cuando fue posible; de lo contrario, se resumió de forma narrativa. Resultados: se incluyeron once estudios. Atosiban no mostró diferencias estadísticamente significativas en retardo del parto contra otros uteroinhibidores. Mostró menor mortalidad neonatal que la indometacina (RR = 0,21; IC 95 %: 0,05 a 0,92), y menor proporción de eventos adversos maternos totales que el fenoterol (RR = 0,16; IC 95 %: 0,08 a 0,31), el nifedipino (RR = 0,48; IC 95 %: 0,3 a 0,78) y la terbutalina (RR = 0,44; IC 95 %: 0,28 a 0,71). Conclusiones: atosiban tiene una eficacia similar para retardar el parto ante la amenaza de un parto pretérmino con otros comparadores (certeza moderada), con ventajas frente a indometacina en mortalidad neonatal (certeza baja) y frente a fenoterol, nifedipino y terbutalina en eventos adversos maternos (certeza moderada).

RESUMO

Abstract Purpose: To investigate the gastroprotective effect of methanol extract of E. spectabilis and its major component isoorientin. Methods: Effects of isoorientin and methanol extract of E. spectabilis were investigated in indomethacin-induced gastric damage model on rats. Famotidine was used as the standard antiulcer drug. Numerical density of ulcer areas and oxidative status were determined on stomach tissues of rats. Results: All doses of isoorientin and methanol extract decreased MDA level and increased SOD activity and GSH levels in the stomach tissue of rats. When numerical density of ulcer areas were analized, the 500 mg/kg dose of methanol extract (84%) exhibited a similar effect to 20 mg/kg dose of standart drug famotidine (87%). Conclusions: The gastroprotective effects of E. spectabilis and its major constituent isoorientin in rats for the first time. Detailed analyses suggested that potential antioxidant activity of both plant extract and isoorientin mediates the gastroprotective effect.

RESUMO

ABSTRACT BACKGROUND: Extracts obtained from plants and fruits provide a relatively safe and practical alternative for the conventional medicine of gastrointestinal diseases. The specie Eugenia mattosii, popularly known in Brazil as "cerejinha", belongs to Myrtaceae family. Species of this family present pharmacological properties, and can be used in the treatment of gastrointestinal disorders. OBJECTIVE: The aim of this study was to determine the phytochemical profile and evaluate the gastroprotective activity of Eugenia mattosii fruits. METHODS: Phytochemical analysis was carried out by thin layer chromatography and gastroprotective assays were performed using two experimental models: acute ulcer model induced by ethanol/HCl and acute ulcer model induced by non-steroidal anti-inflammatory drug (indomethacin). Total lesion area (mm2) and relative lesion area (%) were determined. RESULTS: The results of the phytochemical analysis indicated that the bark and pulp and seeds of E. mattosii present phenolic compounds, terpenes and/or steroids. In gastric ulcer model induced by ethanol was evidenced significant reduction of damaged areas for doses of 50 and 250 mg/ kg of seeds methanol extract, while in the indomethacin-induced ulcer model, all parts of the fruit presented defense capability of the gastric mucosa by reducing lesions at doses of 50, 125 and 250 mg/kg. CONCLUSION: The results demonstrate that the specie E. mattosii has bioactive compounds that provide gastroprotective activity, presenting possible therapeutic potential.


RESUMO CONTEXTO: Extratos obtidos de plantas e frutos fornecem uma alternativa relativamente segura e prática para os remédios convencionais de doenças gastrointestinais. A espécie Eugenia mattosii, popularmente conhecida no Brasil como "cerejinha", pertence à família Myrtaceae. Espécies desta família apresentam propriedades farmacológicas e podem ser utilizadas no tratamento de distúrbios gastrointestinais. OBJETIVO: O objetivo deste estudo foi determinar o perfil fitoquímico e avaliar a atividade gastroprotetora dos frutos de Eugenia mattosii. MÉTODOS: A análise fitoquímica foi realizada por cromatografia em camada delgada e dois modelos experimentais foram utilizados para avaliação da atividade gastroprotetora em camundongos: modelo de úlcera gástrica induzida por anti-inflamatório não-esteroidal (indometacina) e modelo de úlcera gástrica induzida por etanol/HCl. RESULTADOS: Os resultados da análise fitoquímica indicaram que a casca e polpa e as sementes de E. mattosii apresentam compostos fenólicos, terpenos e/ou esteroides. No modelo de úlcera gástrica induzido pelo etanol, foi evidenciada redução significativa de áreas danificadas para doses de 50 e 250 mg/kg do extrato das sementes, enquanto no modelo de úlcera induzida por indometacina, todas as partes do fruto apresentaram capacidade de defesa da mucosa gástrica ao reduzir as lesões nas doses de 50, 125 e 250 mg/kg. CONCLUSÃO: Os resultados demonstram que a espécie E. mattosii possui compostos bioativos com atividade gastroprotetora, apresentando possível potencial terapêutico.

RESUMO

Abstract This study aimed to evaluate the in situ degree of conversion, contact angle, and immediate and long-term bond strengths of a commercial primer and an experimental adhesive containing indomethacin- and triclosan-loaded nanocapsules (NCs). The indomethacin- and triclosan-loaded NCs, which promote anti-inflammatory and antibacterial effects through controlled release, were incorporated into the primer at a concentration of 2% and in the adhesive at concentrations of 1, 2, 5, and 10%. The in situ degree of conversion (DC, n=3) was evaluated by micro-Raman spectroscopy. The contact angle of the primer and adhesive on the dentin surface (n = 3) was determined by an optical tensiometer. For the microtensile bond strength µTBS test (12 teeth per group), stick-shaped specimens were tested under tensile stress immediately after preparation and after storage in water for 1 year. The data were analyzed using two-way ANOVA, three-way ANOVA and Tukey's post hoc tests with α=0.05. The use of the NC-loaded adhesive resulted in a higher in situ degree of conversion. The DC values varied from 75.07 ± 8.83% to 96.18 ± 0.87%. The use of NCs in only the adhesive up to a concentration of 5% had no influence on the bond strength. The contact angle of the primer remained the same with and without NCs. The use of both the primer and adhesive with NCs (for all concentrations) resulted in a higher contact angle of the adhesive. The longitudinal μTBS was inversely proportional to the concentration of NCs in the adhesive system, exhibiting decreasing values for the groups with primer containing NCs and adhesives with increasing concentrations of NCs. Adhesives containing up to 5% of nanocapsules and primer with no NCs maintained the in situ degree of conversion, contact angle, and immediate and long-term bond strengths. Therefore, the NC-loaded adhesive can be an alternative method for combining the bond performance and therapeutic effects. The use of an adhesive with up to 5% nanocapsules containing indomethacin and triclosan and a primer with no nanocapsules maintained the long-term bond performance.

RESUMO

Se presentan dos casos clínicos y la revisión de la literatura actual sobre luxación convergente de codo. En el primer caso, se muestra cómo un retraso en el diagnóstico conducirá a una reducción abierta y fijación con agujas de Kirschner, mientras que un diagnóstico temprano permite la reducción cerrada y el tratamiento conservador como se describe en el segundo caso. La clave de diagnóstico para la luxación convergente de codo radica en la correcta interpretación de las radiografías y el bloque de prono-supinación en el examen físico. Se recomienda el uso de indometacina para evitar calcificaciones heterotópicas. El resultado final es mejor cuando el diagnóstico es precoz, independientemente del método de reducción. Nivel de Evidencia: IV


We describe two clinical cases and review the available literature on convergent elbow dislocation. Our first case shows how a delay in the diagnosis will lead to an open reduction and internal fixation with K-wires. On the other hand, an early diagnosis prompts a closed reduction without fixation as it is described in the second case. The diagnostic key for the convergent dislocation of the elbow lies in the correct interpretation of radiographs and the prono-supination block on physical examination. The use of indomethacin is recommended to avoid heterotopic calcifications. The final outcome is better when an early diagnosis is achieved regardless of the reduction method. Level of Evidence: IV

RESUMO

Abstract Previous studies performed in marine fish (I. conceptionis and G. laevifrons) showed that indomethacin blocked arterial contraction mediated by acetylcholine (ACh). The objective of this study was to determine if contraction induced by acetylcholine is mediated by the cyclooxygenase pathway in several arterial vessels in the Chilean frog Calyptocephalella gayi. Arteries from the pulmonary (PA), dorsal (DA), mesenteric (MA) and iliac (IA) regions were dissected from 6 adult specimens, and isometric tension studies were done using dose response curves (DRC) for ACh (10-13 to 10-3 M) in presence of a muscarinic antagonist (Atropine 10-5 M) and an unspecific inhibitor of cyclooxygenases (Indomethacin, 10-5M). All the studied arteries exhibited vasoconstriction mediated by ACh. This vasoconstriction was abolished in the presence of atropine in DA, MA and IA and attenuated in PA. Indomethacin abolished the vasoconstriction in MA and attenuated the response in PA, DA and IA. Similar to marine fish, C. gayi have an ACh-mediated vasoconstrictor pattern regulated by muscarinic receptors that activate a cyclooxygenase contraction pathway. These results suggest that the maintenance in vasoconstrictor mechanisms mediated by ACh→COX →vasoconstriction is conserved from fish to frogs.


Resumo Estudos feitos em peixes marinhos (I. conceptionis e G. laevifrons) têm demostrado que a indometacina bloqueia a contração arterial mediada por acetilcolina (ACh). O objetivo do presente estudo foi avaliar o efeito da via da ciclooxigenase na contração induzida por ACh em vasos arteriais da rã chilena Calyptocephalella gayi. Foram dissecadas regiões das artérias pulmonares (PA), dorsal (DA), mesentérica (MA) e ilíaca (IA) de seis espécimes adultos e realizados estudos de tensão isométrica utilizando curvas dose-resposta (CDR) de ACh (10-13 a 10-3 M) na presença de um antagonista muscarínico (atropina, 10-5 M) e um inibidor das ciclooxigenases (indometacina, 10-5 M). Todas as artérias evidenciaram uma resposta vasoconstritora mediada por ACh. Esta resposta vasoconstrictora foi suprimida na presença de atropina nas artérias DA, MA, IA e atenuada na PA. A indometacina suprimiu a vasoconstrição na artéria MA e atenuou a resposta nas artérias PA, DA e IA. Tal como os peixes marinhos, a C. gayi tem um padrão de vasoconstrição mediado por Ach que é regulado pelos receptores muscarínicos e pela ciclooxigenase. Estes resultados sugerem a conservação dos mecanismos vasoconstrictores mediados por ACh→COX em peixes e rãs.

RESUMO

ABSTRACT BACKGROUND Given the increase of people with gastrointestinal disorders, the search for alternative treatments with fewer side effects is vital, as well as the demand for food or plants that can help protect the stomach. OBJECTIVE The aim of this study was to evaluate the gastroprotective action of the extracts of wild fruit trees of Myrcianthes pungens (guabiju); Inga vera Willd. (ingá-banana) and Marlierea tomentosa Cambess. (guarapuruna) in in vivo pharmacological models. METHODS The different parts of the fruits were separately subjected to a process of extraction by methanol. Two experimental pharmacological models were conducted in mice; the gastric ulcer model induced by non-steroidal anti-inflammatory (indomethacin), and the gastric ulcer model induced by ethanol/HCl, which allowed us to evaluate the gastroprotective activity of the extracts at a dose of 250 mg/kg. Subsequently, the total lesion area (mm2) and relative lesion area (%) were determined. RESULTS The results showed significant gastroprotective activity against the aggressive agents used - ethanol and indomethacin - for all the extracts tested. CONCLUSION It is assumed that the fruits have bioactive compounds such as antioxidant substances that act on the prostaglandin levels, protecting them from the damage caused by ethanol and indomethacin. These results prompt further studies to isolate and identify the active properties.


RESUMO CONTEXTO Devido ao aumento de pessoas com distúrbios gastrointestinais, a busca de tratamentos alternativos com menos efeitos cola­terais é fundamental, assim como a demanda por alimentos ou plantas que possam ajudar a proteger o estômago. OBJETIVO O presente estudo teve como objetivo avaliar a ação gastroprotetora dos extratos plantas frutíferas silvestres Myrcianthes pungens (guabiju); Inga vera Willd. (ingá-banana) e Marlierea tomentosa Cambess. (guarapuruna) em modelos farmacológicos in vivo. MÉTODOS As diferentes partes do fruto foram submetidas se­paradamente a um processo de maceração em solução metanólica a frio. Foram realizados dois modelos experimentais em camundongos, modelo de úlcera gástrica induzida por anti-inflamatório não-esteroidal (indometacina) e modelo de úlcera gástrica induzida por etanol/HCl, que permitiram avaliar a atividade gastroprotetora dos extratos na dose de 250 mg/kg. Posteriormente, foram determinadas a área total de lesão (mm2) e a área relativa lesada (%). RESULTADOS Os resultados apresentaram atividade gastroprotetora significativa para todos os extratos estudados frente aos agentes agressores utilizados, etanol e indometacina. CONCLUSÃO Supõe-se que os frutos apresentam compostos bioativos, como as substancias antioxidantes, que atuam sobre os níveis de prostaglandinas, protegendo dos danos causados pelo etanol e indometacina. Os resultados encorajam futuros estudos para isolamento e identificação dos princípios ativos dos frutos.

RESUMO

El ductus arterioso permeable sintomático (DAPs) es frecuente en prematuros extremos (PE), siendo importante su cierre para disminuir la repercusión hemodinámica. Para ello se usa indometacina o ibuprofeno con los riesgos subyacentes. OBJETIVO: Caracterizar las complicaciones digestivas y renales en PE tratados por DAPs. PACIENTES Y MÉTODO: Estudio retrospectivo en PE nacidos entre enero de 2004 y diciembre de 2013. Según diagnóstico se distribuyeron en 3 grupos: sin DAPs, con DAPs tratados con indometacina y con ibuprofeno. Se excluyeron PE con otras complicaciones graves. Se evaluaron complicaciones digestivas y renales graves. Se usó significación estadistica con p ≤ 0,05. RESULTADOS: Se enrolaron 599 PE; 33,1% recibió tratamiento por DAPs, 66,9% no lo requirió. Hubo asociación estadística entre DAPs y menor edad gestacional, depresión neonatal y distrés respiratorio. Del grupo no tratado, el 5% presentó enterocolitis y el 0,25% falla renal; entre los tratados el 2,5% presentó enterocolitis y el 1,0% falla renal. No hubo diferencias estadísticas significativas considerando ambas complicaciones (p = 0,17), sólo enterocolitis (p = 0,11) o sólo falla renal (p = 0,33) entre tratados y no tratados; tampoco las hubo al comparar complicaciones entre tratados con indometacina o ibuprofeno. CONCLUSIONES: Los resultados en nuestra población demuestran que el tratamiento médico del DAPs, en ausencia de otras complicaciones clínicas, no representa un mayor riesgo de complicaciones graves digestivas o renales. No se demostraron ventajas entre la indometacina e ibuprofeno.


The symptomatic patent ductus arteriosus (sPDA) is common in extremely premature infants (EPI). In order to decrease the hemodynamic repercussion and avoid complications it is necessary to close it. Indomethacin or ibuprofen are used for this purpose with its associated risks. OBJECTIVE: Characterize digestive and renal complications in EPI who received indomethacin or ibuprofen as sPDA treatment. PATIENTS AND METHOD: Retrospective study on EPI between January-2004 and December-2013. Three groups were compared: treated with indomethacin or ibuprofen and a non-treated group. EPI with other serious complications were excluded. The primary outcomes on each group were digestive and/or renal complications. Statistical significance was p < 0.05. RESULTS: 599 EPI were included, 33.1% with PDA received treatment and 66.9% did not need it. A statistical association was found between sPDA and lower gestational ages, neonatal depression and respiratory distress. In the non-treated group, 5% presented enterocolitis and 0.25% renal failure; on the treated group, 2.5% presented enterocolitis and 1.0% renal failure. No significant differences were found between the treated and non-treated groups in relation to complications considering enterocolitis (p = 0.11) or renal failure (p = 0.33) alone, or combined (p = 0.17). No difference were detected either between those treated with indomethacin or ibuprofen. CONCLUSIONS: The results show that in absence of other clinical complication, medical treatment of sPDA with indomethacin or ibuprofen, do not increase the risk of serious digestive or renal disorders. There were no advantages of using indomethacin or ibuprofen over the other.

RESUMO

Abstract: Eosinophilic pustular folliculitis (EPF) or Ofuji disease is a rare dermatosis, prone to recurrence and chronicity. The peak incidence occurs in the third decade of life and its exact etiology remains unknown. Evidence suggests that the expression of adhesion molecules and the production of cytokines activate the follicular unit, but the stimulus that triggers these changes remains unclear. The three clinical variants reported in the literature include classic EPF, immunosuppression-associated EPF, and infancy-associated EPF. We report a case of eosinophilic pustular folliculitis with peculiar epidemiological characteristics, which represents a challenging therapeutic scenario.
