Consumption of medicinal plants and herbal medicines by children and adolescents with chronic conditions: a survey in a tertiary-care outpatient clinic / Utilização de plantas medicinais e derivados por crianças e adolescentes com condições crônicas: levantamento em um serviço pediátrico terciário

Objectives: Medicinal plants and herbal medicines are widely used worldwide. However, patients with chronic health conditions or their caregivers do not often disclose these practices to their healthcare providers, leading to potentially severe interactions with current treatments, especially in children. We aimed to describe the prevalence of the use of medicinal plants and herbal medicines by children and adolescents with chronic health conditions and whether their physicians were informed about it. Methods: We conducted a cross-sectional electronic survey on parents and caregivers of children and adolescents with chronic health conditions seen at a university, tertiary-care pediatric outpatient clinic. The common names of the plants cited by respondents were reviewed and Latin names of the species were provided whenever possible. Results: From 20,213 text messages sent in May and June 2021, 521 valid responses were obtained. The prevalence of the use of medicinal plants and herbal medicines was 34.6%, most without a medical prescription (self-medication), and few physicians (4.0%) were aware of it. The five most used species were: Mentha spicata L. (mint), Foeniculum vulgare Mill. (fennel), "cidreira" (a common name possibly corresponding to Cymbopogon citratus (DC.) Stapf, Melissa officinalis L. or Lippia alba (Mill.) N.E. Br. ex Britton & Wilson, P.), Matricaria chamomilla L. (German chamomile), and Plectranthus barbatus Andrews (boldo). Conclusions: The prevalence of the use of medicinal plants and herbal medicines by children and adolescents with chronic health conditions in a tertiary-care outpatient clinic was 34.6%, and only a few physicians were aware of it (AU).

Does resveratrol favor peri-implant bone repair in rats with ovariectomy-induced osteoporosis? Gene expression, counter-torque and micro-CT analysis

Abstract This study investigated the influence of resveratrol on peri-implant repair and its effects on bone-related markers in ovariectomy-induced osteoporosis in rats. Animals were divided into: OVX+PLAC (n = 10): ovariectomized animals treated with placebo; OVX+RESV (n = 10): OVX treated with resveratrol; OVX+PLAC+ZOL (n = 10): OVX treated with PLAC and zoledronate; OVX+RESV+ZOL (n = 10): OVX treated with RESV and ZOL; and SHOVX+PLAC (n = 10): sham ovariectomy treated with PLAC. RESV and PLAC were administrated after ovariectomy and ZOL after six weeks after OVX, until the end of experiment. One implant was inserted in each tibiae of animals 18 weeks after ovariectomy. After 4 weeks, one implant was removed for counter-torque, and peri-implant tissue was collected for mRNA quantification of several osteogenic markers by PCR. The other tibia was submitted to micro-computed tomography analysis. Reduced counter-torque values, bone-implant contact (BIC) and bone volume fraction (BV/TV), and higher bone porosity (BP) were detected in OVX+PLAC group when compared to SHOVX+PLAC (p < 0.05). OVX+RESV rats presented lower BIC, BV/TV, and trabecular number (Tb.N), and augmented BP and trabecular spacing (Tb.Sp) when compared to SHOVX+PLAC (p < 0.05). Higher Tb.N and connectivity density (Conn.Dn) and reduced Tb.Sp were observed in OVX rats treated with ZOL, independently of RESV, when compared to OVX+PLAC and OVX+RESV groups (p < 0.05), whereas the combination ZOL+RESV promoted lower BP when compared to OVT+PLAC and OVX+RESV (p < 0.05). Gene expression was not influenced by RESV (p > 0.05), whereas ZOL promoted up-regulation of BMP-2 (p<0.05). RESV did not improve peri-implant bone repair in rats with ovariectomy-induced osteoporosis.

Radioprotective Effect of Nigella Sativa Oil on Heart Tissues of Rats Exposed to Irradition

Abstract Background Various studies are ongoing related to the radioprotective agents. Herbal preparations are currently becoming popular because of their beneficial effects with fewer side effects compared to the synthetic/semi-synthetic medicines, and Nigella sativa oil (NSO) is only one of them. Objective To investigate NSO for its antioxidant effects on the heart tissue of rats exposed to ionizing radiation (IR). Methods Thirty six male albino Wistar rats, divided into four groups, were designated to group I (IR plus NSO group) that received both 5 Gray of gamma IR to total cranium and NSO; group II (IR alone group) that received IR plus saline, group III (control group of NSO) that received saline and did not receive NSO or IR; group IV (control group) that received only sham IR. Alterations in Total antioxidant status (TAS) and Total oxidant status (TOS), Oxidative stres index (OSI), Sulhydryl group (SH), Lipid hydroperoxide (LOOH), Paraoxonase (PON) levels, Arylesterase (ARE) and Ceruloplasmin (CER) activities in homogenized heart tissue of rats were measured by biochemical methods. Results In heart tissue of the rats in the IR alone group (group II) LOOH, TOS and OSI levels were found to be higher, ARE activity and TAS level were found to be lower than all of the other groups (p < 0.01). These results also support that IR increases oxidative stress and NSO's protective effect. Conclusion NSO would reduce the oxidative damage in the irradiated heart tissue in the experimental rat model.

A comparative study of regulations on botanicals registration in Australia and the European Union / 国际中医中药杂志

Australia and EU Member States have been the important components of global herbal medicine market. The legal use of Chinese Materia Medica in Australia and EU Member States is closely related to the internationalization of Chinese medicine, therefore it is of great significance to conduct a comparative study on their herbal medicine registration regulations. By summarizing the regulations issued by Therapeutic Goods Administration (TGA) and European Medicines Agency (EMA), and comparing related definitions and the regulations on quality management and medicinal product registration, we found that the method No.3 of L (A) 3 and the traditional-use registration are more conductive to bringing Chinese patent medicines to market in Australia and the EU Member States.

Longevity of bonded composite restorations after dentin biomodification with neolignans obtained from Nectandra leucantha / Longevidade de restaurações de resina composta após biomodificação de dentina com neolignanas obtidas de Nectandra leucantha

Objective: This in vitro study evaluated the effect of neolignan-containing solutions on dentin biomodification previously applied to the bonding procedure in adhesive restorations. Material and Methods: Neolignans, dehydrodieugenol B­CP1 and dehydrodieugenol B methyl ether­CP2, were isolated from Nectandra leucanthaand two aqueous solutions containing 0.13% neolignans, 0.2% propylene glycol and 3.0% ethanol were prepared. Bovine teeth were ground flat to obtain 2-mm thick specimens which received resin composite restorations (N=10). The neolignan solutions were applied before the bonding procedure (60 s). Experimental groups were: control, untreated group, 0.12% chlorhexidine gel, 0.13% CP1 solution, and 0.13% CP2 solution. A push-out bond strength test was conducted (0.5 mm/min). Bovine tooth sections (0.5×1.7×7.0 mm) were also obtained to assess the modulus of elasticity and mass change after treatment (N=15). A three-point bending test evaluated the elastic modulus of fully demineralized dentine beams after immersion in the solutions. The data were statistically analyzed (α = 0.05). Results: The bond strength of the restorations to dentin was significantly improved by the treatment with neolignan-containing solutions, irrespective of the evaluation time (p<0.05). After 6 months, a significant reduction in the bond strength was observed in the groups treated with the solutions (p>0.05), but the means were significantly higher than the control groups (p<0.05). The elastic modulus of demineralized dentin was significantly improved after the treatment with the solutions (p<0.05). All groups lost mass weight. Conclusion: The solutions improved the in vitro longevity of bonded restorations, possibly due to the dentin biomodification effect of the neolignans.(AU)

Objetivo: Este estudo in vitro avaliou o efeito de soluções contendo neolignanas na biomodificação da dentina aplicadas previamente à restaurações adesivas. Material e Métodos: Neolignanas, desidrodieugenol B­CP1 e éter metílico de desidrodieugenol B-CP2, foram isolados da espécie Nectandra leucantha e duas soluções aquosas contendo 0,13% de neolignanos, 0,2% de propilenoglicol e 3,0% de etanol foram preparadas. Dentes bovinos foram lixados para obter espécimes de 2 mm de espessura e preparos cavitários restaurados com resina composta (N=10). As soluções foram aplicadas em dentina antes do procedimento adesivo (60 s). Os grupos experimentais foram: controle, grupo não tratado, gel de clorexidina 0,12%, solução de CP1 a 0,13% e solução de CP2 a 0,13%. Foi realizado o teste de resistência de união push-out (0,5 mm/min). O módulo de elasticidade e a alteração de massa após tratamento da dentina (0,5×1,7×7,0 mm) foram também avaliados em teste de flexão de três pontos (N=15). Os dados foram analisados estatisticamente (α=0,05). Resultados: A resistência de união das restaurações à dentina melhorou significativamente com o tratamento com as soluções, independentemente do tempo de avaliação (p<0,05). Após 6 meses, foi observada redução significativa da resistência de união nos grupos tratados com as soluções (p>0,05), com médias significativamente maiores do que nos grupos controle (p<0,05). O módulo de elasticidade da dentina desmineralizada aumentou significativamente após tratamento com as soluções (p<0,05). Todos os grupos perderam massa, independentemente do tratamento. Conclusão: As soluções melhoraram in vitroa longevidade das restaurações adesivas, possivelmente devido ao efeito biomodificador da dentina das neolignanas(AU)

La manera más frecuente de consumo de las plantas medicinales fue la vía oral, en forma de infusiones. Las plantas medicinales más utilizadas fueron manzanilla, perejil, eucalipto, boldo, aloe, menta y ruda; y algunas de ellas mostraron efecto teratogénico, estimulante uterino, abortivo, entre otros. Es necesario conocer la cantidad real y la manera más frecuente en que las gestantes consumen las plantas medicinales, con la finalidad de clasificar estos productos de acuerdo al nivel de seguridad que ofrecen y promover el uso racional de la medicina tradicional para contribuir en la salud pública.

This research aimed to find out the frequency and ways of using medicinal plants by pregnant women treated at the Centro de Salud Viña Alta, located in La Molina district. Twenty-one (21) pregnant women voluntarily participated in the study, where they were administered an expert-validated survey regarding the use of medicinal plants. The results showed that 86 % of the pregnant women used medicinal plants and 67 % did not ask their doctor before using them. The most frequent way of using the medicinal plants was by oral intake as herbal teas. The most widely used medicinal plants were chamomile, parsley, eucalyptus, boldo, aloe, mint and rue, some of which produced a teratogenic effect, uterine stimulant action, abortifacient effect, among others. It is necessary to know the actual quantity and most frequent way of using medicinal plants by pregnant women to classify these products as for its safety level and promote the rational use of traditional medicine to contribute to public health.

Efecto de la harina de camu camu sobre el daño hepático inducido por acetaminofén en ratones / Effect of camu camu flour on acetaminophen-induced liver damage in mice

RESUMEN Objetivos. Evaluar el efecto de la harina de Myrciaria dubia (camu camu) sobre el tejido hepático inducido a toxicidad por acetaminofén en ratones. Métodos. Diseño experimental. Se preparó una suspensión de harina de camu camu (HCC) con almidón al 1,6%. Se emplearon 40 ratones machos de la cepa BALB/c, con un peso promedio de 30,8 g y de dos meses de edad, los cuales fueron divididos en cinco grupos, recibiendo el siguiente tratamiento, vía orogástrica, por un período de 10 días, grupos I y II: almidón 1,6% 10 mL/kg; grupo III: HCC 200 mg/kg, grupo IV: HCC 500 mg/kg y grupo V: HCC 800 mg/kg. Al 6to día de tratamiento se le administró acetaminofén (300 mg/kg) a los grupos II-V hasta el 10mo día. Terminada la intervención los animales fueron puestos en ayunas de 12 horas, para luego ser sacrificados previa anestesia con pentobarbital sódico. Se extrajo el hígado, se identificó y seccionó el lóbulo mayor para el estudio bioquímico e histológico. Resultados. La harina de camu camu redujo los niveles del índice hepático, y presentó un mejor perfil del sistema glutatión, comparado con el grupo II; sin embargo, las cifras de lipoperoxidación no mostraron diferencia significativa. A nivel histológico, en los grupos que recibieron HCC se observaron hepatocitos binucleados, así como un mayor mantenimiento de la polaridad; sin embargo, algunas muestras evidenciaron microvacuolas y leve fragmentación de la cromatina. Conclusión. La harina de camu camu evidenció efecto hepatoprotector frente a la toxicidad por acetaminofén en ratones.

RESUMEN Se realizó un estudio transversal con el objetivo de evaluar el uso de terapias de medicina alternativa y complementaria (MAC) y sus factores asociados, en la provincia de Coronel Portillo (Ucayali), durante el 2013. Se realizaron 917 encuestas a los jefes de hogar, residentes en tres distritos de la provincia (Callería, Manantay y Yarinacocha), en las que se calculó la proporción de uso de MAC y se analizó la relación con variables sociodemográficas (edad, sexo, grado de instrucción, estado civil, ocupación e ingreso económico). 179 encuestados (19,5%) mencionaron que utilizaron MAC en los últimos doce meses. Se encontró una relación estadísticamente significativa entre el uso de terapias de MAC y el grado de instrucción (p < 0,001), la ocupación de la persona encuestada (p < 0,001) y su ingreso económico mensual (p < 0,001). Futuras investigaciones definirán las asociaciones encontradas y las variables intervinientes.

ABSTRACT A cross-sectional study was carried out to evaluate the use of complementary and alternative medicine (CAM) therapies and the factors associated with it, in the province of Coronel Portillo (Ucayali) during 2013. A total of 917 surveys were carried out among household heads in three districts of the province (Callería, Manantay and Yarinacocha), in which the proportion of CAM use was calculated and the relationship with sociodemographic variables (age, sex, educational level, marital status, occupation and income) was analyzed. From the total, 179 respondents (19.5%) mentioned that they used CAM in the last 12 months. A statistically significant relationship was found between the use of CAM therapies and educational level (p < 0.001), respondent's occupation (p < 0.001) and monthly income (p < 0.001). Future research will define the found associations and the variables involved.
