Objective: The healing effects of two different dilutions (۵ & ۱۰۰%) of N-Chromosome Royal Jelly and ANGIPARS ointment were investigated and measured on experimental injuries in streptozotocin (STZ)-induced diabetic rats. This study investigated the healing effects of ۲ different N Chromosome Royal Jelly dilutions on injuries of STZ-induced diabetic rats. Materials and Methods: For diabetes induction, male Wistar rats received STZ (۵۵ mg/kg) intraperitoneally and plasma glucose level measurement after ۷۲ hours demonstrated diabetes induction. Rats were randomly divided into ۵ groups of ۶ members and one square centimeter (cm۲) wound was surgically induced in the dorsal region of each rat. The test groups were treated with ANGIPARS, undiluted royal jelly N chromosome, and royal jelly N chromosome ۵% separately. The control groups were including non-diabetic and untreated diabetic rats. Results: The findings indicate a significant acceleration in wound healing of the diabetic rats treated by ANGIPARS ointment or royal jelly N chromosomes ۵%. RJ also shortened the healing period of desquamated skin lesions. Thus, RJ possesses an anti-inflammatory action and is able to augment wound healing, but does not have an insulin-like action in streptozotocin-diabetic rats. Conclusion: Regarding the mentioned findings, royal jelly as a natural product may play an effective role in treating chronic wounds in mice, which makes it a proper candidate for use in human wound repair. Nonetheless, it seems that determination of the suitable dilution of this compound will result in better effects, thus more studies are recommended.
