Histological findings of regeneration in retrieved pasteurized bone grafts.

Background: Despite a number of radiologic evaluations of the incorporation of pasteurized bone (PB) in human and histologic evaluations in animal models, there has been a scarce documentation regarding the histologic evaluation of PB from human. Herein, we present histologic findings of regeneration in retrieved PB graft from pediatric and adult patients.

Methods: PB was retrieved for various reasons in 7 patients (10-52 years old).

Lactobacillus acidophilus ameliorates pain and cartilage degradation in experimental osteoarthritis.

Osteoarthritis (OA) is a chronic and degenerative disease that causes pain, cartilage deformation, and joint inflammation. Lactobacillus species have been used as dietary supplements to induce the production of antimicrobial and anti-inflammatory factors. The goal of this study was to determine whether Lactobacillus acidophilus ameliorates monosodium iodoacetate-induced OA.
