Effects of leptin on fracture healing in rat tibia

Öz:
Amaç: Bu çalışmada leptinin kırık iyileşmesi üzerine olabilecek muhtemel etkileri değerlendirildi. Gereç ve yöntemler: Kasım 2009 - Mayıs 2010 tarihleri arasında ortalama yaşları 16 hafta ve ortalama vücut ağırlıkları 323 g (dağılım; 295-352 g) olan 54 Sprague Dawley erkeksıçan çalışmaya alındı ve rastgele eşit üç gruba ayrıldı. Bütünsıçanlarda standart tibia kırığı oluşturuldu. Grup 1’e 0.5 mlserum fizyolojik, grup 2’ye 0.1 μg/kg leptin 0.5 ml serum fizyolojik, ve grup 3’e ise 0.3 μg/kg leptin 0.5 ml serum fizyolojik içinde olacak şekilde 14 gün boyunca intraperitoneal olarak uygulandı. Her bir grup da kendi içerisinde ikinci,üçüncü ve beşinci haftalarda değerlendirilmek için altışarsıçandan oluşan üçer alt gruba ayrıldı. Bulgular: Radyolojik değerlendirme sonucunda yalnızca beşinci haftada grup 3’ün kırık iyileşmesi, grup 1’e kıyasla,daha iyiydi (p= 0.014). Histolojik değerlendirmede üçüncü haf-tada grup 3’ün kırık iyileşmesi, grup 1’e kıyasla, daha iyiydi(p= 0.011). Beşinci haftada ise hem grup 2, hem de grup 3,grup 1’e kıyasla, daha iyi kırık iyileşmesine sahipti (sırasıyla, p= 0.006, p= 0.002). Grup 2 ve 3 arasında beşinci haftada kırık iyileşmesi açısından anlamlı bir fark yoktu (p=0.176). Sonuç: Leptin sıçan tibia kırık iyileşmesi üzerine dozabağımlı olarak olumlu etkiye sahiptir.

Objectives: In this study, we aimed to evaluate possible effects of leptin on fracture healing.Materials and methods: Between November 2009 and May2010, 54 male Sprague Dawley rats with a mean age of 16weeks and a mean body weight of 323 g (range; 295-352 g)were included and randomly divided into three equal groups.Standardized tibial fractures were created to all rats. Group 1was treated with 0.5 mL physiological saline, group 2 wastreated with 0.1 μg/kg leptin within 0.5 mL physiologicalsaline, and group 3 was treated 0.3 μg/kg leptin within 0.5 mL physiological saline for 14 days intraperitoneally. Each group was divided into three subgroups including six rats for the evaluation at second, third and fifth weeks. Results: Radiological evaluation showed that fracture healing of group 3 was better than group 1 (p= 0.014) only at fifth week. Histological evaluation revealed fracture healing of group 3 was better than group 1 at third week (p= 0.011). At fifth week, both group 2 and group 3 had better fracture healing than group 1 (p= 0.006, p= 0.002, respectively). There was no statistically significant difference in fracture healing between group 2 and 3 at fifth week (p= 0.176). Conclusion: Leptin has a positive dose-dependent effect on rat tibial fracture healing.
