Comparative Clinical Pathology > 2012 > 21 > 6 > 1421-1425

It has been suggested that obstruction of coronary veins can induce myocardial infarction similar to coronary artery obstruction. In this study, the coronary veins of the sheep heart were blocked experimentally and haematological and inflammatory indices (haptoglobin, serum amyloid A, tumour necrosis factor-α and interferon-γ) alterations were studied. Twenty sheep were used for this study. Anaesthesia...

Ureteral segment replacement using an ovine fetal urachus duct (new xenogenic graft) in dogs

A. S. Bigham, M. Shadkhast, S. Sharifi, A. R. Mohammadnia, more

Comparative Clinical Pathology > 2009 > 18 > 2 > 125-129

The ureter is an important part of the urinary system that can be affected by several disorders such as congenital malformations, extensive iatrogenic ureteral obstruction, ureteritis, retroperitoneal fibrosis, trauma, necrosis, calculi, tumors, etc. We wished to determine whether ovine fetal urachus duct will be accepted when used as a ureteral replacement material in other species. The ureters of...

Comparison of novel xenograft (bovine fetal growth plate) and allograft effects on experimental bone defect healing in rabbit

A. S. Bigham, S. N. Dehghani, Z. Shafiei, S. Torabinezhad

Comparative Clinical Pathology > 2009 > 18 > 4 > 345-351

Large bone defects resulting from trauma, tumors, osteitis, implant loosening, or corrective osteotomies require surgical therapy because spontaneous regeneration is limited to relatively small defects. Currently, transplantation of autografts or allografts, mineral bone substitutes, and callus distraction are the most commonly used techniques for skeletal reconstruction. Each method has significant...

Autogenous bone marrow concurrent with static magnetic field effects on bone-defect healing: radiological and histological study

A. S. Bigham, M. Shadkhast, S. N. Dehghani

Comparative Clinical Pathology > 2009 > 18 > 2 > 163-168

To stimulate the process of bone healing, several methods have been used previously. These methods include use of ultrasound, electrical stimulation, exposure to electromagnetic field, bone graft, interporous hydroxyapatite (as a bone graft substitute). The aim of this study was evaluation of bone-defect healing with autogenous bone marrow concurrent with static magnetic field. Twenty adolescents,...

Experimental bone defect healing with xenogenic demineralized bone matrix and bovine fetal growth plate as a new xenograft: radiological, histopathological and biomechanical evaluation

A. S. Bigham, S. N. Dehghani, Z. Shafiei, S. Torabi Nezhad

Cell and Tissue Banking > 2009 > 10 > 1 > 33-41

The following study was designed to evaluate xenogenic bovine demineralized bone matrix (DBM) and new xenograft (Bovine fetal growth plate) effects on bone healing process. Twenty male White New Zealand rabbits were used in this study. In group I (n = 10) the defect was filled by xenogenic DBM and in group II (n = 10) the defect was filled by a segment of bovine fetal growth plate and was fixed by...

Fresh cortical autograft versus fresh cortical allograft effects on experimental bone healing in rabbits: radiological, Histopathological and Biomechanical evaluation

Z. Shafiei, A. S. Bigham, S. N. Dehghani, S. Torabi Nezhad

Cell and Tissue Banking > 2009 > 10 > 1 > 19-26

Bone grafting is used to enhance healing in osteotomies, arthrodesis, and multifragmentary fractures and to replace bony loss resulting from neoplasia or cysts. They are source of osteoprogenitor cells and induce bone formation and provide mechanical support for vascular and bone ingrowth. Autografts are used commonly but quantity of harvested bone is limit. This study was designed to evaluate fresh...

Journal of Orthopaedics and Traumatology > 2008 > 9 > 2 > 73-80

Background Bone grafting is used to enhance healing in osteotomies, arthrodesis, and multifragmentary fractures and to replace bony loss resulting from neoplasia or cysts. They are source of osteoprogenitor cells and induce bone formation and provide mechanical support for vascular and bone ingrowth. Autografts are used commonly but quantity of harvested bone is limited. The aim of this study is to...

Cell and Tissue Banking > 2008 > 9 > 2 > 91-99

Bone grafting is used to enhance healing in osteotomies, arthrodesis, and multifragmentary fractures and to replace bony loss resulting from neoplasia or cysts. They are source of osteoprogenitor cells and induce bone formation and provide mechanical support for vascular and bone ingrowth. Autografts are used commonly but quantity of retrieved bone is limit. This study was designed to evaluate autograft...
