Often asked: In The Insulin And Diabetes Experiment What Was The Effect Of Administering Alloxan?

What was the effect of administering insulin to the diabetic rat?

When the liposomes were administered orally to rats in the 3rd phase of acute alloxan diabetes, reduction of the blood glucose level was observed in 7 of 11 animals, the reduction persisted for several hours and was ranging from 30 to 75%.

What is alloxan induced diabetes?

Alloxan-induced diabetes is a form of insulin-dependent diabetes mellitus that occurs as a result of alloxan administration or injection to animals [78], [79]. It has been successfully induced in a variety of animal species; rabbits, mice, rats, monkeys, cats and dogs [80], [81].

How does alloxan induce diabetes in rodents?

Diabetes in rodents is induced by injecting alloxan or streptozotocin which induce diabetes while producing ROS leading to demolition of pancreas β-cells [8, 9]. The prime cause of a number of long term complications of diabetes is chronic hyperglycemia.

What is alloxan treatment?

Alloxan is a toxic chemical. It has been used to induce diabetes in experimental animals by destroying the insulin-secreting cells of Langerhans islet in pancreas. Antioxidant. It provides protection against some of the damage induced by free radicals.

What are the side effects of alloxan?

After injection of alloxan at the dose of 40 mg/kg, only a slight transient hyperglycemia was seen during the first 15 d. At 2 mo after alloxan injection, however, glucose- and carbachol-stimulated insulin secretion were markedly impaired in all animals treated with alloxan, including those with normoglycemia.

What is the difference between alloxan and streptozotocin?

Alloxan not only has toxic effects on islets of Langerhans, but also affect other body organs. It usually produces severe diabetes. Streptozotocin is more specific to beta cells rather than alloxan. strptozotocin has high inductive capacity than alloxan and its less toxic to the pancreas compared to alloxan.

Can alloxan induced type 2 diabetes in rats?

Alloxan and STZ induce T1DM in adults rats. But you can use STZ in newborn rats to induce T2DM. Alloxan cannot be used to induce T2DM. Some available models include fructose-fed, high fat diet fed followed by a low dose of STZ and STZ/nicotinamide.

How do rats induce diabetes?

For induction of experimental diabetes in male adult rats weighted 250-300 grams (75-90 days), 60mg/kg of Streptozotocin was injected intravenously. Three days after degeneration of beta cells, diabetes was induced in all animals.

How does hyperglycemia occur?

Hyperglycemia, or high blood glucose, occurs when there is too much sugar in the blood. This happens when your body has too little insulin (the hormone that transports glucose into the blood), or if your body can’t use insulin properly. The condition is most often linked with diabetes.

What is alloxan found in?

The name is derived from allantoin, a product of uric acid excreted by the fetus into the allantois, and oxaluric acid derived from oxalic acid and urea, found in urine. Alloxan was used in the production of the purple dye murexide, discovered by Carl Wilhelm Scheele in 1776.
