Oral Dose of Citrus Peel Extracts Promotes Wound Repair in Diabetic Rats

M. Ahmad, M.N. Ansari, A. Alam and T.H. Khan

Diabetic patients wound healing is slower than the healthy individuals. Three citrus peel extracts; Lemon (Citrus limon), Grapes fruits (Citrus paradise) and Orange (Citrus sinensis) promote wound healing in experimental animals. This study investigated the effect of oral treatment with citrus peel extracts on wound repair of the skin of diabetic rats. The extracts were estimated for vitamin C and total carotenoid contents prior to animal study. Diabetes mellitus was induced in rats by intraperitoneal injection of a single dose of streptozotocin (STZ, 75 mg kg-1 b.wt.). One week after diabetes induction, full thickness excision wounds were made in hyperglycemic rats and were divided groups, each containing 6 rats. The different test group animals were treated with different citrus peel extract orally at the dose of 400 mg kg-1 body weight daily for 12 days. The blood glucose, body weight and rate of wound closure of each rat were measured every 3rd day during the experimental period. At the end of experiment, granular tissues of wounds were removed and estimated for hydroxylproline and total protein content. The results showed significant reduction in blood glucose and time to wound closure. Tissue growth and collagen synthesis were significantly higher as determined by total protein and hydroxyl proline content. From our experimental data, we propose that oral administration of citrus peel extracts has a therapeutic potential in the treatment of chronic wounds in diabetes.

Good evening
I am an Msc student from Israa university in Jordan
im doing a research about wound healing using different plant extract and im facing a problem with knowing how to process skin rat and estimate total protein, i have total protein kit from sigma aldrich, the problem im facing is that is that i don't know the amount of skin i should use and how to prepare it in order to estimate the total protein content in the skin, i tried to contact the authors but i didn't find any way to contact them, i really need any help i can get, thank you
best regards
