5 Serum glucose levels were determined using glucose-oxidase method. The intra- and interassay variances were 2% and 4%, respectively. Fifty µl of serum was used for the measurement of insulin by immunoradiometric assay (Biosource INS-IRMA Kit). The

intra- and interassay variances were 4% and 8%, respectively. Lipid profile, FIRI, alanin transaminase (ALT), and alkaline phosphatase (ALP) were determined by commercial kits and enzymic ways.11 Statistical Analysis The data were expressed as mean±SEM. Data http://www.selleckchem.com/products/Erlotinib-Hydrochloride.html distribution was assessed by Shapiro-Wilk’s test. The data were analyzed by one-way ANOVA and post hoc least significant different (LSD) tests. A P value Inhibitors,research,lifescience,medical of ≤ 0.05 was considered as significant. Results Effect of Fructose Administration Compared to control group, daily administration of fructose for eight weeks was associated with significant increase in blood glucose (P<0.05), insulin (P<0.001), and FIRI (P<0.001) (figures 1-3). Effect of Urtica Dioica Extract Compared to vehicle, Urtica dioica

extract Inhibitors,research,lifescience,medical at 100 mg/kg (P<0.01) and 200 mg/kg (P<0.001) significantly decreased serum glucose (figure 1). Moreover, compared to the vehicle, Urtica dioica at 50, 100 and 200 mg/kg significantly (P<0.001) decreased serum Inhibitors,research,lifescience,medical insulin and FIRI (figures 2 and ​and33).

Effect of Urtica Dioica Extract on Lipid

Profile Daily administration of fructose for eight weeks did not change serum TG, total cholesterol, VLDL, LDL-cholesterol, HDL-cholesterol, isothipendyl LDL/HDL ratio compared to those of the control group (table 1). Table 1: The values (mean ±SEM, n=8 each) of serum lipid profile, hepatic enzymes, and leptin of control, fructose-treated and Urtica dioica extract-treated (50, 100, 200 mg/kg/day) rats Compared to the fructose group, Urtica dioica extract at 50 mg/kg significantly (P<0.05) increased serum TG and VLDL-cholesterol, and significantly (P<0.05) decreased serum LDL and LDL/HDL ratio (table 1). Moreover, compared to fructose group, the extract at 100 and 200 mg/kg/day significantly (P<0.05) increased TG, and significantly (P<0.05) decreased LDL and LDL/HDL ratio.
