ABSTRACT

The therapeutic approaches for Type 2 Diabetes Mellitus rely most on the usage of oral hypoglycaemic drugs. These drugs have adverse side effects and hence alternative medicines are continuously explored. The present study intends to investigate the antidiabetic potential of the flavonoids present in Gracilaria corticata. The flavonoids were isolated (FEGC) and their inhibitory activity on the carbohydrate hydrolysing enzymes such as α-amylase and α-glucosidase was analysed. The flavonoids were found to inhibit α-amylase and α-glucosidase with an IC50 value of 302 µg and 75 µg respectively. The synergistic effect of FEGC and luteolin was also investigated and the results show that both FEGC and luteolin inhibited synergistically at half their IC50 values. The observations of this study reveal that the flavonoids of G. corticata have potential antidiabetic activity and can act independently or synergistically in the management of Type 2 Diabetes Mellitus

ABSTRACT

Introdução: Uma diástase do músculo reto abdominal (DMRA) de 3 cm ou mais em puérperas é considerada acima dos padrões de normalidade e poderão trazer maiores complicações como dores lombares, limitações funcionais e herniações das vísceras abdominais. Objetivo: Mensurar a DMRA em puérperas, na Maternidade do Hospital Satélite, e correlacionar com paridade, idade da puérpera, peso do recém nascido (RN) e sedentarismo. Material e métodos: Estudo transversal, observacional, com uma amostra de 30 puérperas, examinadas no mês de novembro de 2008 em relação à paridade, ao sedentarismo e ao peso do RN. Resultados: A multiparidade foi o que apresentou uma maior relação ao aumento de DMRA, quando comparada ao grupo primigestas/secundigestas (p = 0,003). A média da DMRA em sedentárias foi de 3,7 cm e para as não sedentárias foi de 2,8 cm (p < 0,05). O peso do RN tem influência de 11,47 por cento sobre a diástase (p < 0,067). A variável que mais evidenciou uma correlação positiva com o aumento da DMRA foi a faixa etária da gestante com influência de 42,99 por cento sobre DMRA (p < 0,008).Conclusão: A paridade, a prática de atividade física, o peso do RN e, principalmente, a idade da gestante influenciam diretamente na variação do tamanho da DMRA durante o período de gestação.


Introduction: A diastasis recti of the rectus abdominis muscle (RAMD) of 3 cm width or more is considered out of the acceptable patterns and can cause other commitments such as back pain, functional limitations and abdominal visceral herniation. Objective: To measure the RAM in post childbirth woman at the Maternity of Satélite Hospital in Teresina, Piauí, Brazil, and to correlate it to parity, mother’s age at delivery, newborn weight and sedentarism. Method: This was a transversal and observational study with 30 women examined at immediate post-partum on November 2008 in terms of parity, sedentarism and newborn weight. Results: High parity factor showed a higher relation to the diastase increase when was compared first pregnancy and second pregnancy group (p = 0.003). The average of RAMD in sedentary women was 3.7 cm comparing to 2.8 cm in non-sedentaries (p < 0.05). The newborn weight has 11.47 percent of influence over diastase (p < 0,067). The variable that most influenced with a positive correlation with RAMD was the mother age at delivery (42.99 percent over RAMD, p < 0.008). Conclusion: Parity, physical activity, newborn weight and, mainly, age of pregnant woman are factors that influence RAMD size range during pregnancy.
