Background: Pomegranate (punicagranatum L, Punicaceae), is an edible fruit consumed around the world. The edible part of pomegranate is rich in compounds that possess antioxidant and anti-inflammatory activities. The aim of this study is to investigate the antioxidant; anti-inflammatory and gingival wound healing effects of Punicagrantum L. seed extract oral supplementation in rabbit. Methods and Methods: Forty five male rabbits were divided into 3 groups, base line (5 rabbits) left without buccal gingival wound as( group 1),study group, 20 rabbits (group2) with buccal gingival wound treated with ethanolic extract of Punicagranatum L. seed extract and control, 20 rabbits (group 3) with buccal gingival wound only. Buccal gingival wounds were created on lower right central incisor and sutured removed after (7) days. Blood biopsies by cardiocentesis were collected at times (0, 3h, 1, 3 and 7days) for estimation of serum alkaline phosphatase activity, serum total proteins, and serum uric acid. Results: The results showed a significant increase in serum Alkaline phosphatase, total proteins and uric acid in all time intervals after buccal gingival wound, in rabbits receiving water, while their levels increased significantly only at time intervals of 3 hours and 1 day after gingival wound, in rabbits receiving pomegranate seed extraction. Conclusions: It has been concluded that oral Supplementation of pomegranate seed extract in rabbits can expedite the rate of healing of gingival wound

Background and aim: Pomegranate is a medicinal herb that can promote healing of periodontal tissue through differentiation of mesenchymal cells both in vivo and in vitro. Therefore, this study is to investigate the effect of oral supplementation of Punicagranatum L. peel extract on bone defect in rabbit. Methods: Forty five male rabbits were divided into 3 groups; group 1; baseline group(5 rabbits) left without bone defect. Group 2; study group (20 rabbits) with bone defect model that received daily 1ml of oral supplementation of pomegranate peel extract (PoPx). Group 3; control group (20 rabbits) with bone defect model that received distilled water. Bone defect was done into facial plate of lower right central incisor. Blood biopsies by cardiocentesis at times (base line, 3h, 1, 3 and 7days) for estimation of serum calcium, phosphorous, and vitamin D levels. Results: The results showed a significant increase in serum calcium and phosphorous levels only after 3 hours and 1 day of bone defect, in rabbits receiving water and rabbits receiving pomegranate peel extraction. Serum vitamin D level shows significant increase in all time intervals reaching maximum value after three days in rabbits receiving pomegranate peel extract, while no significant change was observed in rabbits receiving water. Conclusions: Supplementation of pomegranate peel extract can increase vitamin D absorption, thus it may promote the bone healing process.

Background: Pomegranate (PG) fruit (punicagranatum L, Punicaceae contains many bioactive substances that play important role in the treatment of a variety of medical problems. Among PG parts, it was observed that the peel had the most potent antioxidant activity. Objective: To evaluate some serum antioxidants levels in mandibular bone injury healing in rabbits orally supplemented with pomegranate peel extract (PPE). Patients and Methods: Forty-five male rabbits (1-1.2 kg) were used and they were divided into 3 groups; the baseline group consisted of 5 rabbits without creating mandibular bone defects. 20 rabbits were used as a study group with creating mandibular bone defects and they received orally 1ml/day of PPE. Another 20 rabbits were used as a control group with creating mandibular bone defects without receiving PPE. For each rabbit of both study and control groups, a circular defect of 3 mm in diameter was made in the mid labial area of the alveolar bone of the lower right central incisor. Blood samples were taken from the baseline group and both the study and control groups at time intervals; 3hrs, 1, 3, and 7days after bone defect creation, for estimation of serum albumin (Alb), bilirubin (Bili), zinc (Zn), and magnesium (Mg) levels. Results: Serum Bili levels significantly increased 1and 3 days after bone defect creation in both study and control groups, while the levels returned back to baseline in a study group, 7 days after the operation. Serum Alb, Zn, and Mg levels showed a significant decrease in study and control groups, 1 day and 3 days after the operation, while the levels of these parameters returned back to baseline, in a study group, 7 days after bone defect. Conclusion: Supplementation of PPE can affect serum antioxidants and this was accompanied by the increase in the bone healing rate process.

Background: Pomegranate (Punica granatum) is an edible fruit that has been described as a medical and therapeutic functional food in the Middle East and the Mediterranean. Objective: To investigate the use of serum creatinine (Cr) level and creatine kinase (CK) activity as indicators for gingival wound healing process rate in rabbits, supplemented on pomegranate seed extract (PSE). Patients and Methods: A total of 45 rabbit males were used. They were divided into 3 groups; 5 rabbits as a baseline group that left without a buccal gingival wound. 20 rabbits (5 rabbits per each time interval) as a study group with buccal gingival wound with PSE supplementation, and another 20 rabbits (5 rabbits per each time interval) as a control group with gingival wound without PSE supplementation. A buccal gingival wound was created on the lower right central incisor, and the suture was removed after (7) days. Blood samples were collected for the baseline group and at time intervals; 3 hour, 1, 3, 7 days after creating the wound for both control and study groups to determine serum Cr and serum CK. Results: Serum Cr and CK significantly increased in all time intervals after gingival wounds, in the control group compared with baseline values. Whereas the levels significantly increased in rabbits receiving PSE at intervals of 3 hours, 1 and 3 days after gingival wound, they returned to the baseline values, seven days after gingival wound incision. Conclusion: Serum Cr and CK increase in the buccal gingival wound, while oral supplementation of PSE can decline them to the baseline value after a period of time, therefore these parameters can be used as indicators for gingival wound healing rate.
