RESUMO
Background:Diabetes mellitus is the one of the most common endocrine diseases that is characterized by hyperglycemia, altered metabolism with an increased risk of much complications. Besides drugs classicallyused for the treatment of diabetes several species of plants have been described as having a hypoglycemic activity with decreased side effects. Aim of the Work:This work aimed to investigate the possible anti-diabetic effect of oral administration of pumpkin (Cucurbita maxima) fruit flesh and seeds powders on Streptozotocin induced diabetic rats via studying blood glucose levels, oxidative biomarkers as well as islets of Langerhans structure changes.Materials and Methods:60 adult albino rats of Sprague-Dawely strains (200±5 gm) were classified into five groups of ten animals each except diabetic control group was composed of twenty rats as follow Group I:healthy control;Group II:diabetic control ,Group III,IVandV: diabetic rats received 2g pumpkin fruit, seeds, fruit and seeds mixture powders respectively /kg body weight daily by oral intubation Results:The results of present study showed that pumpkin powders caused significant improvements (P≤0.05) in blood glucose, insulin levels and glycated hemoglobin percent compared to diabetic control group. Also pumpkin powders improved antioxidants activities andhealed Langerhans islets by increasing their number and size in comparison with diabetic control group. Conclusion:The present study showed that pumpkin powders may normalize the various biochemical and pancreatic tissues abnormalities resulted due to diabetes metabolic disorders and it is a source of potent anti-diabetic agent. The diabetic rats that were administered with the pumpkin fruit powder, exhibited the highest improvements.
RESUMO
La necrobiosis lipoidica es una dermatosis poco frecuente, de origen desconocido. Puede observarse en pacientes sin alteración de la glucosa, pero frecuentemente está asociada a la diabetes mellitus bien establecida. Menos común es que estas lesiones en la piel aparezcan en estadios prediabéticos. Se describe el caso de una paciente femenina, de 65 años de edad, que hace 10 años comenzó a presentar una lesión papuloeritematosa de 1 cm, con bordes bien definidos, en la cara lateral interna de la pierna derecha. Recientemente le realizan biopsia de la lesión dermatológica y prueba de tolerancia a la glucosa oral, y se diagnostica necrobiosis lipoidica y tolerancia a la glucosa alterada respectivamente. Se piensa que los pacientes con esta enfermedad deben tener seguimiento a largo plazo, para diagnosticar oportunamente diabetes mellitus u otros estados prediabéticos(AU)
Necrobiosis lipoidica is a rare dermatosis of unknown origin. It can be observed in patients with unaltered glucose indexes but frequently associated to well-established diabetes mellitus. It is even less common that this type of skin lesions occur in pre-diabetic staging. This is the case of 65 years-old woman, who had presented 1 cm-long papulloerythematous lesion with well-defined contours for 10 years in the inner lateral side of her right leg. She had been recently biopsied in her cutaneous lesion and made a glucose-tolerance test, which yielded necrobiosis lipoidica and altered glucose tolerance. It is considered that the patients with this disease should be followed-up for a long period to timely diagnose diabetes mellitus or other pre-diabetic conditions(AU)
