Protective Effects of Modeled Superoxide Dismutase Coordination Compound (MSODa) Against Ischemia/Reperfusion Injury in Rat Skeletal Muscle.

Background/aim: Ischemia/reperfusion (I/R) injury of skeletal muscles is common pathophysiology during surgeries and the superoxide dismutase (SOD) plays a critical role in this process. SOD-modeled coordination compound (MSODa) may simulate the protective effects as SOD.

Methods: Therefore, this study was designed to explore the protective effects and underlying mechanism of MSODa on malondialdehyde (MDA) and integrin-β2 (CD11b/CD18) in plasma, myeloperoxidase (MPO) and intercellular cell adhesion molecule-1 (ICAM-1) in tissue, and morphological changes before and after I/R injury.

Rare massive osteolipoma in the upper part of the knee in a young adult.

Lipoma is a common benign soft tissue tumor. This article describes a massive osteolipoma, an unusual lipoma that is fixed to the femoral periosteum. A 21-year-old man presented with a subcutaneous mass at the knee region, which had been present for more than 36 months, and a slight limitation of joint flexibility.

[The fate of donor bone cells in different diameter bone grafts: an experiment study].

Objective: To investigate the fate of donor bone cells in bone grafts of different diameters during repairing bone defects.

Methods: One hundred sixteen female syngeneic inbred DA rats were established as radial defect model of 3 kinds: structural bone grafting group (n = 56), morselized bone grafting group (n = 56), and blank group (without bone grafting, n = 4), to be used as receptors The ilia of 58 male inbred DA rats, as donors, were harvested and made into structural bone grafts 2 mm in diameter and morselized bone grafts 0.3 - 0.
