Summary: | Syzygium cumini is a plant that has been used in popular medicine for the treatment of insulin dependent diabetes mellitus (DMID). This study verified the effect of Syzygium cumini upon the regeneration of insulin producing cells in the pancreatic duct wall. The animals were divided into four groups, control (C), treated control (TC), diabetic control (DC) and treated diabetic (TD). An aqueous extract from Syzygium cumini bark was given by gavage in a daily dose of 1g/kg of body weight. After a thirty day period the animals were euthanized and the pancreas taken to immunohistochemical analysis. In this study, it was observed the positive staining for insulin on cells of the pancreatic duct and connective tissue in the pancreas of TD and TC animals. These results indicate that Syzygium cumini bark extract stimulates development of insulin positive cells from the pancreatic duct epithelial cells.
O Syzygium cumini é uma planta medicinal que tem sido utilizada popularmente para o tratamento da diabetes melito insulino dependente (DMID). Este estudo verificou o efeito do extrato da casca de Syzygium cumini sobre a regeneração de células insulino-positivas, a partir do ducto pancreático, no pâncreas de ratos normais e diabéticos. Os animais foram divididos em grupo controle (C), controle tratado (CT), diabético controle (DC) e diabético tratado (DT). Nos grupos tratados foi realizada a administração oral do extrato aquoso da casca de Syzygium cumini, na dose de 1g/kg de peso vivo. Após um período de 30 dias, os animais foram submetidos à eutanásia e o pâncreas retirado para análise imunohistoquímica. Neste estudo, foram visualizadas células insulino-positivas no ducto pancreático e no tecido conjuntivo próximo a ele, no pâncreas dos animais dos grupos DT e CT. Estes resultados indicam que o tratamento com o extrato da casca de Syzygium cumini na dose de 1g/kg estimula a formação de células insulino-positivas a partir das células epiteliais do ducto pancreático. |
