RESUMO
Background: The study was done to evaluate the role of Vitamin D (Vit D) in an experimental model of type II DM and compare its effects with oral hypoglycemic drugs (Metformine). Methods: 30 male rats were divided; control group, Diabetic group via administration of high fat diet then injection of streptozotocin . Diabetic rats were then divided into Diabetic group, Diabetic + Metformine group(n=6), Diabetic +Vit D (n=6), Diabetic + Metformine +Vit D (n=6). Fasting glucose, insulin, HOMA IR, Cholesterol, Triglycerides, C-Reactive protein (CRP), Glucagon like peptide (GLP1), Cyclooxygenase 2 (COX2) and Superoxide dismutase (SOD) were measured, Real time PCR for pancreatic expression levels of Caspase 3, IKKβ and Western plot of Pancreatic protein kinase beta (Akt) and INGAP (islet neogensis associated protein), and histopathological, immunohistochemical for pancreatic tissue. Results: Increased glucose, fasting insulin, HOMA IR , cholesterol, triglycerides, CRP, COX2 and expression of levels of Caspase 3 and IK Kinase B and Akt in diabetic group in comparison to control. On the other hand, significant decreased levels of GLP1, SOD and INGAP in diabetic in comparison to control. On treatment with metformine or Vitamin D improved all parameters. In combined metformine and vitamin D therapy there was much improvement with no significant change from control. Conclusions: Vitamin D and metformine improved inflammatory, oxidative stress, apoptotic conditions in an experimental model of type II DM and combined therapy causes more improvement, so it is better to give combined therapy.
RESUMO
The aim of this study was to determine whether there is a relationship between prolonged use of metformine on bone mineral density, comparing a group of patients receiving prolonged treatment with metformine and a control group with similar characteristics biodemographic. Material and Methods: A case-control study was conducted in a population of 225 postmenopausal women between 51 and 62 years of age, were divided into 2 groups, one of type 2 diabetic patients treated with 1,000-2,000 mg. of metformine for at least 5 years (n = 75) and they had an acceptable metabolic control (HbA1c < 7.5 percent), and a control group of non diabetic women (n = 150). BMD at the lumbar spine (L1-L4) and both hips were measured with DEXA. Results: The group of type 2 diabetes treated with metfornine was associated with a significantly increased bone mineral density at the lumbar spine compared with the control group (L1-L4 g/cm2 1.07 +/- 0.15 vs 0.16 +/- 0.975) (L1-L4 T score-0.68 +/- 1.06 vs -1.73 +/- 1,07) (p = 0.05).Conclusion: Prolonged therapy metformine could have an effect on the preservation of bone mineral density at the lumbar spine in women with diabetes type 2, suggesting an effect of metfornine osteoprotective in trabecular bone.

Se realizó una intervención terapéutica en 12 pacientes con obesidad exógena, atendidos en la consulta de Endocrinología del Hospital Provincial Docente Clinicoquirúrgico "Saturnino Lora Torres" de Santiago de Cuba, desde julio de 2013 hasta igual mes de 2014, quienes fueron seleccionados aleatoriamente y luego asignados a 2 grupos de idéntica cantidad de integrantes: el de control, que realizó dieta como única terapéutica, y el de estudio, que recibió dieta y metformina como tratamiento; a fin de determinar la eficacia de este medicamento en la pérdida de peso. La información fue analizada y procesada mediante las pruebas de hipótesis de Mann Whitney y de comparación de medias, con un error de 5 %, y se obtuvo que este medicamento resultó más eficaz combinado con la dieta, que la monoterapia dietética como único tratamiento.
A therapeutic intervention was carried out in 12 patients with exogenous obesity, assisted in the Endocrinology Department from "Saturnino Lora Torres" Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba, from July, 2013 to the same month of 2014, who were randomly selected and then assigned into 2 groups of identical quantity of members: a control group which had the diet as the only therapy, and that of study which received diet and metformine as treatment; in order to determine the effectiveness of this drug in the weight loss. The information was analyzed and processed through the hypothesis tests of Mann Whitney and of means comparison, with an error of 5%, and it was obtained that this drug was more effective combined with the diet that the dietary monotherapy as the only treatment.
