Effectiveness of a low-fat yoghurt supplemented with rooster comb extract on muscle strength in adults with mild knee pain and mechanisms of action on muscle regeneration.

PURPOSE: To determine the effects of the intake of low-fat yoghurt supplemented with rooster comb extract (RCE) on muscle strength. METHODS AND RESULTS: 148 subjects, with mild knee pain, participated in a randomized, placebo-controlled, double-blind, and parallel study. Muscle strength, knee effusion, and pain perception were measured. C2C12 myoblasts were used to elucidate the mechanisms of action involved. RCE improved total work and mean power in men, and also peak torque in extension by 10%. RCE reduced synovial effusion by 11.8% and pain perception by 24.6%. Both RCE and HA increased myoblast proliferation by 29%, while RCE reduced myoblast differentiation by 36.2%, suggesting a beneficial role of RCE in muscle regeneration. CONCLUSIONS: Low-fat yoghurt supplemented with RCE improved muscle strength. This effect is partially explained by muscle regeneration enhancement, reduced synovial effusion, and reduced pain perception, which could exert a beneficial clinical impact on men affected by mild knee pain.

A low-fat yoghurt supplemented with a rooster comb extract on muscle joint function in adults with mild knee pain: a randomized, double blind, parallel, placebo-controlled, clinical trial of efficacy.

Preliminary results suggested that oral-administration of rooster comb extract (RCE) rich in hyaluronic acid (HA) was associated with improved muscle strength. Following these promising results, the objective of the present study was to evaluate the effect of low-fat yoghurt supplemented with RCE rich in HA on muscle function in adults with mild knee pain; a symptom of early osteoarthritis. Participants (n = 40) received low-fat yoghurt (125 mL d(-1)) supplemented with 80 mg d(-1) of RCE and the placebo group (n = 40) consumed the same yoghurt without the RCE, in a randomized, controlled, double-blind, parallel trial over 12 weeks. Using an isokinetic dynamometer (Biodex System 4), RCE consumption, compared to control, increased the affected knee peak torque, total work and mean power at 180° s(-1), at least 11% in men (p < 0.05) with no differences in women. No dietary differences were noted. These results suggest that long-term consumption of low-fat yoghurt supplemented with RCE could be a dietary tool to improve muscle strength in men, associated with possible clinical significance. However, further studies are needed to elucidate reasons for these sex difference responses observed, and may provide further insight into muscle function.

Evaluación de las aplicaciones locales de una solución limpiadora suave con Dinafitol de Bardana y pH8: estudio realizado en consulta privada / Evaluation of the local application of a mild cleansing solution: study carried out in private consultation

Estudio realizado en consulta privada de los 17 médicos participantes, en 150 pacientes con vulvovaginitis, de los que se reportan 148 casos provenientes de tres principales ciudades del Ecuador (Guayaquil, Quito y Cuenca).Tipo de estudio: Abierto, multicéntrico, no comparativo.Objetivo: Evaluar la eficacia y tolerancia de una solución limpiadora suave con contenido de Bardana, en el período previo al tratamiento específico, como ayuda en el control del prurito y eritema presentes en las vulvovaginitis.Material y método: Se utilizó una solución limpiadora suave con contenido de Dinafitoles de Bardana y nivel de pH 8. Fueron reclutadas 150 pacientes de acuerdo a los criterios de inclusión, no inclusión y exclusión. La sintomatología fue evaluada al inicio y al final del estudio. Se recomendó el uso del producto en higiene local dos veces al día por siete días mientras se esperaba el resultado del examen cito bacteriológico vaginal.Resultados:•98.0% de mejoría y desaparición del prurito.•96.5% de mejoría y desaparición del eritema.En cuanto a la tolerancia al producto utilizado, el 95.3% reportó la calificación de “buena”.Conclusión: Se logró demostrar la utilidad de la solución limpiadora suave con pH8 y contenido de Dinafitol de Bardana, concluyendo que su utilización está justificada en los casos de vulvovaginitis y que, gracias a la tolerancia y aceptación de las pacientes se puede recomendar también su uso cotidiano en la higiene íntima y corporal. Por los resultados obtenidos, podemos considerar el uso de esta solución limpiadora como de primera elección en el manejo de las patologías relacionadas con el prurito y eritema y como un excelente coadyuvante en el tratamiento etiológico de las vulvovaginitis en las que con frecuencia advertimos la presencia de esta sintomatología.

Study carried out in the private consultation of 17 doctors selected to participate in the study that included 150 patients with vulvovaginitis, of which 148 cases are reported from in the three main cities of the Ecuador, (Guayaquil, Quito and Cuenca). Type of study: Open, multicentral, not comparative. Objective: To evaluate the effectiveness and tolerance of a mild cleansing solution, containing Bardana, during the period prior to a specific treatment, in order to help the control of pruritus and erythema present in the vulvovaginitis. Material and method: A mild cleansing solution with a pH level 8 was used. 150 patients were recruited according to the inclusion and exclusion criteria of the study. The symptoms were evaluated at the beginning and at the end of the study. The use of the product was recommended twice a day for seven days while expecting the results of the bacteriological vaginal exam.Results:•98.0% of improvement and disappearance of pruritus.•96.5% of improvement and disappearance of erythema. As for the tolerance to the use of product, 95.3% of the patients reported it as “good”. Conclusion: It was possible to demonstrate the how important is the use of the mild cleansing solution with a pH 8. We conclude that its use is justified in the case of vulvovaginitis and that thanks to its tolerance and the patients' acceptance, it may also be recommended to be used daily in the intimate and corporal hygiene. With the reported results, one can consider the use of this mild cleansing solution as the first election in the handling of pathologies related with pruritus and erythema and as an excellent help for etiological treatment of the vulvovaginitis in those that frequently notice the presence of this symptoms.
