OBJECTIVE To investigate the feasibility and clinical results of applying poly-DL-lactic acid (PDLLA) biomembranes in cleft palate repair. METHODS 68 cleft palate patients were divided into study group and control group. The traditional surgical method was used to control group to close the soft

Compacts weighing 40 mg and containing triamcinolone acetonide 70-90% and polyhydroxybutyric acid (PHB) 30-10% or poly (DL-lactic acid) 20% with a diameter of 5 mm were bonded onto the side-wall of molar teeth. In vitro dissolution studies showed the compacts to release 12% of drug in 30 days with

The design of a plasticized, biodegradable polymeric material, suitable for application as a controlled-release system, was attempted. A poly(DL-lactic acid) oligomer was plasticized with 1,2-propylene glycol and glycerol. The latter plasticizer showed poor compatibility whereas 1,2-propylene glycol

Poly(alpha-hydroxy acid)s derived from lactic and glycolic acid are bioresorbable polymers which can cover a large range of thermal, physical, mechanical, and biological properties. Human keratinocytes have been shown as able to grow on a poly(DL-lactic acid) film. However the keratinocyte growth

OBJECTIVE To study the effect of internal fixation with absorbable intramedullary nail on the treatment of phalange fractures in replantation of severed finger. METHODS From September 2001 to October 2003, 28 cases with industrial severed finger (21 males and 7 females, with the age of 18-35 years)

Regenerative medicine strategies to promote recovery following traumatic brain injuries are currently focused on the use of biomaterials as delivery systems for cells or bioactive molecules. This study shows that cell-free biomimetic scaffolds consisting of radially aligned electrospun poly-l/dl
