Levels of lipid peroxidation in liver, kidney, brain and blood, liver glutathione (GSH) and several enzymes in liver tissue associated with antioxidant defence mechanism, namely Catalase (EC: 1.11.1.6), GSH reductase (EC:1.6.4.2) and GSH-S-transferase (EC: 2.5.1.18), were investigated in streptozotocin-induced diabetic rats. The single intraperitoneal injection of streptozotocin (65 mg/kg) caused a four-, eight- and seven-fold increase in lipid peroxidation in brain, liver and kidney, respectively. A decline in GSH levels both in blood (two-fold) and liver (16%) compared with normal counterparts was also observed. A marginal increase in catalase activity, a 20% decrease in GSH reductase and an increase of GSH-S-transferase activity was also found in this experimental diabetic condition. These results suggest experimental diabetes, induced by streptozotocin, can produce biochemical changes not only in pancreas but also in liver, kidney and brain tissue.

UI	MeSH Term	Description	Entries
D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D008297	Male		Males
D010088	Oxidoreductases	The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9)	Dehydrogenases,Oxidases,Oxidoreductase,Reductases,Dehydrogenase,Oxidase,Reductase

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
