RESUMEN
Abstract Objectives: this study aimed to investigate the effect of education and auriculotherapy on stress, anxiety, and depression, and coping responses in mothers with premature infants. Methods: this is a randomized clinical trial study at Bahar Hospital carried out with 90 mothers with premature infants admitted to the neonatal intensive care unit. Those eligible for hospitalization were included in the study and distributed into three groups before intervention: (30 ones in the control, training, and auriculotherapy groups, respectively). The mean stress, anxiety, depression, and coping responses in mothers were measured both at the beginning of the study and before neonatal discharge. Results: there was no statistically significant difference in terms of anxiety, stress, and depression scores between the three groups before the intervention. However, after the intervention, there was a significant statistical difference between these three groups, which was among the mean scores of anxiety, stress, and depression. In terms of coping responses, the mean emotional and problem-oriented score in all three groups before and after the intervention is statistically significant. Conclusions: educating mothers and auriculotherapy pressure therapy are simple and practical methods in reducing anxiety, stress, depression, and increase coping responses; consequently, they can be used in neonatal intensive care.
Resumo Objetivos: este estudo teve como objetivo investigar o efeito da educação e da auriculoterapia no estresse, ansiedade e depressão e nas respostas de enfrentamento em mães com bebês prematuros. Métodos: este é um estudo de ensaio clínico randomizado no Bahar Hospital realizado com 90 mães de bebês prematuros internados em unidade de terapia intensiva neonatal. Os elegíveis para internação foram incluídos no estudo e distribuídos em três grupos antes da intervenção: (30 nos grupos controle, treinamento e auriculoterapia, respectivamente). O estresse médio, ansiedade, depressão e respostas de enfrentamento em mães foram medidas no início do estudo e antes da alta neonatal. Resultados: não houve diferença estatisticamente significativa nos escores de ansiedade, estresse e depressão entre os três grupos antes da intervenção. No entanto, após a intervenção, houve uma diferença estatística significativa entre esses três grupos, que foi entre a pontuação média de ansiedade, estresse e depressão. Em termos de respostas de enfrentamento, a pontuação média emocional e orientada para o problema em todos os três grupos antes e depois da intervenção é estatisticamente significativa. Conclusões: a educação das mães e a terapia de pressão com auriculoterapia são métodos simples e práticos na redução da ansiedade, estresse, depressão e aumento das respostas de enfrentamento; conseqüentemente, podem ser utilizados em terapia intensiva neonatal.
RESUMEN
Objective: To determine the effects of syringic acid on hepatic damage in diabetic rats.Methods: Diabetes was induced by streptozotocin. Diabetic rats were given syringic acid at doses of 25, 50 and 100 mg/kg by oral gavage for 6 weeks. Syringic acid effects on the liver were evaluated by examination of plasma biochemical parameters, and pathological study. In addition, biomarkers of lipid peroxidation and antioxidant status of liver tissues were assessed. Real time-PCR was performed to investigate the mRNA expression levels of mitochondrial biogenesis indices in different groups. Results: Syringic acid significantly attenuated the increase in most of plasma biochemical parameters in diabetic rats. Moreover, syringic acid treatment increased the catalase activity while it reduced the superoxide dismutase activity and hepatic malondialdehyde level in diabetic rats. There was no difference between the glutathione content of the treated and untreated groups. These findings were supported by alleviation of histopathological damages in the syringic acid-treated groups compared to the untreated diabetic group. Syringic acid also significantly up-regulated the hepatic mRNA expression of PGC-1α, NRF-1, and NRF-2 and increased the mtDNA/nDNA ratio in diabetic rats. Conclusions: Syringic acid can be considered as a suitable candidate against hepatic complications since it can reduce oxidative damages in diabetic cases. Furthermore, it has the potential of targeting hepatic mitochondria in diabetes.
