ABSTRACT
We studied the effects of streptozotocin (STZ)-induced diabetes on the body weights of animals and the relative weights of kidney, liver and pancreas in albino rats. The aim of the study was to find an association between the reduction in the body weights of diabetic animals and the relative weights of kidney, liver and pancreas in proportion to the body weight of animals in albino rats. This study was performed in the Department of Anatomy and Institute of Pharmaceutical Sciences, Baqai Medical University, Karachi and Pathology department of College of Physicians & Surgeons (CPSP) Pakistan in 2007-08. Diabetes was induced by a single dose of STZ (45 mg/kg, b.w.) given intraperitoneally in sodium citrate buffer at pH 4.5. Eighty albino rats were divided into five groups control (A) and STZ treated (B, C, D, and E) which were sacrificed 2, 4, 6 and 8 weeks post treatment respectively. All the animals were weighed prior to the administration of streptozotocin and at sacrificial time. Kidney, liver and pancreas were removed, dried and weighed on Sartorius balance. The body weights of animals in different groups changed at variable time intervals. The Kidney weight was significantly increased, liver weight was slightly increased while the weight of pancreas was unaffected when compared with the weight of diabetic animals. It seems that the STZ-induced diabetes causes a significant reduction in the body weight of diabetic animals while the relative weights of kidney and liver were increased and the weight of pancreas was unaffected.
RESUMEN
Se estudiaron en ratas albinas los efectos de la diabetes inducida por estreptozotocina (STZ) sobre el peso corporal de los animales y los pesos relativos de riñón, hígado y páncreas . El objetivo del estudio fue encontrar una asociación entre la reducción del peso corporal de los animales diabéticos y los pesos relativos de riñón, hígado y páncreas en proporción al peso corporal de los animales. Este estudio fue realizado en el Departamento de Anatomía, Instituto de Ciencias Farmacéuticas, Universidad Médica Baqa y Departamento de Anatomía Patológica del Colegio de Médicos y Cirujanos Pakistán (CPSP) en 2007-08. La diabetes fue inducida por una dosis única de STZ (45 mg / kg de peso corporal) administrados por vía intraperitoneal en tampón de citrato de sodio a pH 4,5. Ochenta ratas Wistar se dividieron en cinco grupos control (A) y STZ tratadas (B, C, D y E), que se sacrificaron 2, 4, 6 y 8 semanas después del tratamiento respectivamente. Todos los animales fueron pesados antes de la administración de estreptozotocina, y en el momento del sacrificio. El riñón, hígado y páncreas fueron removidos, secados y pesados sobre una balanza Sartorius. El peso corporal de los animales en los diferentes grupos cambió en intervalos de tiempo variables. El peso del riñón aumentó significativamente, el peso del hígado se incrementó ligeramente, mientras que el peso del páncreas no se modificó en comparación con el peso de los animales diabéticos. Parece que la diabetes inducida por STZ causa una reducción significativa del peso corporal de los animales diabéticos, mientras que el peso relativo de los riñones y elhígado se incrementaron y el peso de páncreas no se vio afectado.
