Safety and efficacy of hydroalcoholic extract from Lawsonia inermis leaves on lipid profile in alloxan-induced diabetic rats.

BACKGROUND

Dyslipidemia is one of the most common risk factor for cardiac-related disorders in diabetes mellitus. Diabetic dyslipidemia is characterized by hypertriglyceridemia, low high density lipoprotein and elevated low density lipoprotein concentration.

OBJECTIVE

To explore the effect of Lawsonia inermis hydroalcoholic extract (LIHE) for diabetic dyslipidemic activity along with its safety profile.

METHODS

LIHE administered at doses of 100, 200 and 400 mg/kg in rats after induction of hyperglycemia by alloxan. Insulin (1 IU/kg), glibenclamide (2.5 mg/kg), and metformin (100 mg/kg) were used as positive control and 1% gum acacia as normal control. Statistical analysis was performed using one-way analysis of variance, followed by Dunnett's t-test.

RESULTS

The percentage reduction in blood glucose level of LIHE at dose of 400 mg/kg was 39.08% on day 21 when compared to baseline (day 0), which is comparable to glibenclamide (44.77%) and metformin (46.30%). Decrease in blood glucose level exhibited significant improvement in lipid profile, plasma albumin, total plasma protein and serum creatinine.

CONCLUSIONS

Results of this study demonstrated that LIHE significantly improved lipid and lipoprotein pattern observed in diabetic rats and this could be due to improvement in insulin secretion or action, thus has potential to be used in treatment of diabetes mellitus associated dyslipidemia.
