Urtica Pilulifera in Treating Pre-diabetic Rat Model to Control the Blood Glucose, Lipids and Oxidative Stress

Pre-diabetic precedes the development of full diabetes. Studying and identification changes in pre-diabetic conditions can give the possibility to decline the development of diabetes and treat conditions associated with diabetes such as cardiovascular diseases.

The main objectives of the present study were to investigate the potential of using Urtica pilulifera in treating the pre-diabetic rat model and to investigate its anti-oxidant impact.

The pre-diabetic model was induced in rats through daily giving high sucrose diet (35%) for 30 days. The extraction of U. pilulifera leaves was made as described by previous studies. Thirty male Wistar rats were randomly divided into three groups, control group (n=10), pre-diabetic group (n=10), and treated group with the extract of U. pilulifera (n=10). Control group rats received standard diet; pre-diabetic group rats received standard diet and high sucrose (35%) in drinking water, treated group rats received the same conditions as a pre-diabetic group, with intra-peritoneal injection of U. pilulifera injection on daily basis. After one month experiment, blood samples were taken from all rats and tested for glucose, triglycerides, cholesterol, GSH, TAC, and MDA.

Both glucose and triglycerides levels were significantly increased in pre-diabetic groups, and significantly reduced in the treated group by the extract of U.pilulifera. The cholesterol level was not significantly changed in all groups. The levels of GSH were significantly reduced in the pre-diabetic group compared with the control group. Treatment with the extract of U. pilulifera increased the levels of GSH significantly compared with the pre-diabetic group. The levels of TAC were not significantly changed between the control group and the pre-diabetic group, but significantly increased in the treated group compared with the pre-diabetic group. The levels of MDA significantly increased in the pre-diabetic group compared with the control group, and significantly reduced in the treated group compared with the control group.

High sucrose pre-diabetic model is a good model to study diabetes at early stages, and the treatment using U. pilulifera has several benefits in reducing glucose and lipid profile lipids as well as combating oxidative stress.
