ABSTRACT

We studied the effects of streptozotocin (STZ)-induced diabetes on kidney morphology, anatomy, architecture and on the activities of aminotransferases (AST and ALT), alkaline phosphatase (ALP) and pseudocholinesterase (PChE) in albino rats. The aim of the study was to investigate the association between diabetic kidney complications and kidney enzyme alterations. 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 (80) 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. Histopathology of kidney showed lesions similar to human glomerulosclerosis, glomerular membrane thickening, arteriolar hyalinization and tubular necrosis. Increased levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and pseudocholinesterase (PChE) were observed in the kidney. It seems that the diabetic complications in the kidney are likely to be associated with alterations in enzyme levels.


Se estudiaron los efectos de la diabetes inducida por estreptozotocin (STZ) sobre la morfología, anatomía, arquitectura y sobre las actividades de aminotransferasas (ALT y AST), fosfatasa alcalina (ALP) y pseudocolinesterasa (PChE) en los riñones de ratas albinas. El objetivo del estudio fue investigar la asociación entre las complicaciones renales diabéticas y la alteración de las enzimas renales. Este estudio se realizó en el Departamento de Anatomía y el Instituto de Ciencias Farmacéuticas, Universidad de Medicina Baqai, Karachi y el departamento de Patología de Colegio de Médicos y Cirujanos (CPSP) Pakistán entre el 2007-2008. La diabetes fue inducida por una dosis única de STZ (45 mg / kg de peso corporal) administrada por vía intraperitoneal en tampón de citrato de sodio a pH 4.5. Ochenta (80) ratas albinas fueron divididas en cinco grupos: control (A) y STZ tratados (B, C, D y E), que se sacrificaron a las 2, 4, 6 y 8 semanas después del tratamiento, respectivamente. La histopatología del riñón mostró lesiones similares a la glomeruloesclerosis en humanos, engrosamiento de la membrana glomerular, hialinización arteriolar y necrosis tubular. Aumento de los niveles de aspartato aminotransferasa (AST), alanina aminotransferasa (ALT), fosfatasa alcalina (ALP) y pseudocolinesterasa (PChE) fueron observados en el riñón. Parece que las complicaciones de la diabetes en el riñón están directamente asociadas con alteraciones en los niveles de las enzimas.
